Li Yu created a vast space and had Abant swallow the Scepter of the Emperor, rescuing Himeko’s group and bringing them to his location. After Pandora removed something from the Scepter, Li Yu revealed a hidden consciousness, and a changed, pink-haired girl appeared, leaving the Astral Express crew unsure whether she was March 7th.

• Li Yu expanded a sturdy space to roughly the size of the Solar System and explained to Herta how mastering laws could lead to Aeon-level power.
• Herta decided to devote herself to researching magic and invited Li Yu to her space station, but he refused to become her research subject.
• Li Yu ordered Abant to swallow the Scepter of the Emperor, then transferred himself, Herta, and Himeko’s group to the created space.

• A pink-haired girl holding an umbrella appeared, startling Himeko, while Mr. Yang doubted that she was really March 7th.

Evernight revealed to the Astral Express crew that she was a hidden second soul within March 7th and asked them to keep her existence secret. After the crew returned, Li Yu shared his plan to search for his missing companions across universes, and Herta agreed to help investigate a signal from his old phone.

• Evernight admitted that she and March 7th shared one body, asked the crew to keep her existence secret, and returned to March 7th.
• Li Yu told Himeko and the others that Evernight was an Emanator, and Star lamented that she seemed to be the only one without hidden power.
• Screwllum invited Lygus to Planet Screwllum to study Zandar's research, and the two departed together.
• Herta chose to stay on Li Yu's Abant and study magic rather than return to the space station.
• Li Yu told Herta that he suspected his missing companions had traveled to another universe and planned to search for them using a signal from his old phone.
• Herta examined Li Yu's phone, recognized its unfamiliar signal frequency, and agreed to use her connections to search the universe for a matching signal.

Li Yu explained the Imaginary Tree and Sea of Quanta to Herta, who became eager to explore the Sea and began studying magic. As Herta rapidly advanced in magic, she wondered what would happen if a Stellaron powered a mage.

• Herta began scanning the Universe for the signal from Li Yu's phone, and Li Yu explained that his companions might be lost in other dimensions and world bubbles.
• Li Yu told Herta about the Sea of Quanta, and Herta asked him to take her there; he warned that her Path and much of her technology would be useless inside it.
• Li Yu contacted Pandora, who said Asuna and the others were helping Liyue fight the gods, then gave Herta potions to increase her magic power.
• Herta meditated with Li Yu's help and quickly reached the level of a third-rank mage, then tested a Piercing Magic Bullet against Abant's wall.
• Herta wondered what would happen if a Stellaron powered a mage, and Li Yu joked that it could create a nuclear-powered mage.

Herta tested whether Stelle’s Stellaron could store mana, and Li Yu confirmed that it could. Stelle and March 7th began learning to cultivate while Herta went to gather Stellarons, and Li Yu received an unexpected message from Hakio.

• Herta summoned Stelle after proposing that Stellarons could solve the mana shortage.
• Stelle and March 7th met Li Yu, and Li Yu tested whether Stelle’s Stellaron could absorb and store mana.

• Li Yu gave Stelle and March 7th a meditation technique, and they began cultivating.
• Li Yu received a message from Hakio containing a file and a note that he might need the technology.

Elio sent Li Yu a technique for implanting Stellarons, and Herta used it to implant one in herself and March 7th so they could use Stellarons as magical energy. Li Yu accepted Himeko’s invitation to join the Astral Express and planned to board the train to step onto the Path of Trailblaze.

• Elio sent Li Yu the Stellaron implantation technique, then vanished from his friend list after explaining that the future had become impossible to predict.
• Herta returned with two Stellarons, and Li Yu showed her Elio’s technique after offering to implant one in her.
• Herta examined the technique, implanted a Stellaron into herself, then implanted the other into March 7th.
• Himeko explained that Stellarons could help March 7th and Star learn magic, and urged them to train with Li Yu.
• Star planted a Trailblazing beacon at the library entrance, and Li Yu asked to join the Astral Express as a Nameless.
• Himeko gave Li Yu a golden ticket and explained that Pom-Pom would confirm his identity before he could step onto the Path of Trailblaze.

Li Yu helped March 7th learn to use the Stellaron and gave Stelle a painful shortcut to learning beginner spells. He joined the Nameless as an Emanator of Trailblaze, causing a surge across the universe, then decided against becoming an Aeon and considered taking the Astral Express to Teyvat.

• Herta taught March 7th how to use the Stellaron as a power core, while Li Yu implanted beginner spell knowledge in Stelle and left her rolling in pain.
• After Stelle recovered and refused further lessons, Li Yu asked Himeko to take him to Pom-Pom so he could become one of the Nameless.
• Pom-Pom accepted Li Yu's ticket, and his past journeys sent a huge surge of energy through the Path of Trailblaze and the Star Rail.
• Aha celebrated the Path's revival, while Li Yu became an Emanator of Trailblaze and sensed he could become its Aeon if he chose.
• Li Yu rejected becoming an Aeon and considered using the Astral Express to explore Teyvat.

After becoming an Emanator, Li Yu halted his progress and planned to use Trailblaze beacons to reach other worlds and break Nous's knowledge blockade. He proposed opening a route to the Sea of Quanta, and Welt Yang revealed he had crossed it before and joined the research project.

• Li Yu returned to Abant, studied how Trailblaze beacons worked, and discussed with Pandora a project to find the worlds where Asuna and Asagi Aiba were.
• Li Yu drafted a plan to open a passage to the Sea of Quanta through spatial collapse and brought it to Herta, who questioned the experiment's danger.
• Li Yu mentioned the Sea of Quanta loudly enough to draw Welt Yang over, then asked him for advice.
• Welt Yang said he had traveled through the Sea of Quanta to reach this world and offered to join the experiment so he might find his way home.
• Li Yu suggested involving Lygus, and Herta agreed to gather him, Screwllum, Ruan Mei, and other geniuses for the research.

Herta gathered support and arranged for her space station to come to Amphoreus while Li Yu continued studying True Magic. In Liyue, Asuna and her companions helped defeat Osial, then agreed to help Ningguang capture the remaining Fatui Harbinger.

• Herta invited Lygus, Screwllum, and Ruan Mei to join the True Magic project, and Asta arranged supplies and the space station's arrival in Amphoreus.
• Arcueid hurled giant meteorites at Osial, and Zhongli resealed the Demon God after Ningguang proved she was willing to sacrifice the Jade Chamber for Liyue.
• Asuna asked Ningguang whether she wanted Childe killed, but Ningguang chose to demand an explanation from Snezhnaya because Childe was a diplomat.
• Ningguang asked Asuna and her companions to clear the Fatui from Liyue, and Kato Megumi went ahead to locate the other Harbinger.
• Kato Megumi found the Harbinger inside Northland Bank without being detected and messaged Asuna and the others.

Asuna, Yukino, Arcueid, and Kato Megumi defeated and captured La Signora at the Northland Bank, then handed her over to Yelan. Meanwhile, Zhongli let Ningguang’s plans proceed, while Li Yu welcomed Ruan Mei and the other Genius Society members to Abant for their upcoming experiment.

• Asuna, Yukino, Arcueid, and Kato Megumi overwhelmed La Signora at the Northland Bank, and Arcueid bound her with Dendro power that suppressed her abilities.
• Asuna and the others escorted La Signora outside and handed her to Yelan and the Millelith, fulfilling Ningguang’s instructions.
• Zhongli watched the capture without intervening and reflected that Ningguang could use the two captured Harbingers to demand concessions from Snezhnaya.
• Li Yu showed Ruan Mei around Abant, claimed its living organism had been converted into a machine, and heard her propose discussing it after the experiment.
• Ruan Mei joined Herta, Lygus, and Screwllum in preparing the experiment while regarding Li Yu as an unusually fascinating life-form.

Li Yu and several geniuses began experiments to open a passage to the Sea of Quanta, sealing off the area to keep the IPC and other forces from interfering. After their device successfully opened a stable passage, a probe revealed that time and distance within it were unpredictable, so Li Yu called for Welt Yang to inspect the results.

• Herta ignored the IPC’s attempts to contact her, and Li Yu used the Scepter of the Emperor to screen Abant and cut off outside observation.
• Asta arranged the equipment, and Herta began the spatial-collapse experiment with Li Yu monitoring changes in space.
• After several days of adjustments, the device opened a dark passage that Li Yu judged to be stable, though its destination was unknown.
• Screwllum sent a mechanical beetle through the passage; it returned five minutes late, and its footage showed the Sea of Quanta beyond.
• Li Yu asked for Welt Yang to examine the beetle, and an Ex-Machina summoned him from the library.

Li Yu and the others confirmed that the mysterious passage led to the Sea of Quanta and set course for Welt Yang’s arrival point in the Elwens-3 star system. Meanwhile, the Xianzhou Marshal and Jing Yuan verified that Li Yu’s Meditation Method could alleviate mara and decided to make it public.

• Screwllum showed footage of the passage to Welt Yang, who recognized the blue radiance as the Sea of Quanta and identified the Elwens-3 star system as the place where he had appeared.
• Li Yu ordered Abant to travel toward Elwens-3 while keeping the passage device active, but the space inside became chaotic during the jump and damaged the device.
• Herta, Screwllum, Lygus, and Ruan Mei went off to pursue their research, while Welt Yang contacted Himeko to tell her the group had left.
• Jing Yuan confirmed that meditation eased his mara symptoms and contacted the Marshal, who called a meeting of the other generals.
• The Marshal explained the Meditation Method’s results to the generals and decided to make the method public.

The Marshal released Li Yu’s Meditation Method across the Xianzhou to help suppress the Mara-Struck condition, while keeping the principles of True Magic private. Two days later, Herta opened a quantum gate on Abant, and Welt Yang confirmed that it led to the Sea of Quanta.

• The Marshal and the generals agreed to promote the Meditation Method as a way to suppress the Mara-Struck condition and credit Li Yu with developing it.
• Yaoguang successfully produced magical power with the method, while the Marshal said Li Yu had cut off contact with everyone.
• The generals publicized the method across the Xianzhou, and residents began meditating after confirming it was genuine.
• Li Yu and the others arrived at Abant, where Herta started the machine to open a quantum gate.
• The gate opened onto the Sea of Quanta, and Welt Yang confirmed its destination before Herta asked him what dangers to expect.

Welt Yang explained the Sea of Quanta’s dangers, and Li Yu, Herta, Ruan Mei, and Lygus entered to explore it. After Quantum Phantoms attacked Herta’s base, they discovered magic could defeat them and returned to plan a larger expedition.

• Welt Yang described Quantum Phantoms, the Lost, and high-dimensional observers, while Ruan Mei asked about the Phantoms.
• Li Yu, Herta, Ruan Mei, and Lygus entered the Sea of Quanta as Screwllum stayed behind to guard the passage; they found their Paths cut off and could use only power from within themselves.
• Herta built a laboratory base from nanobots and summoned her little Hertas to equip it.
• Quantum Phantoms attacked and gnawed at the base, so Herta dismantled it after some of her nanobots malfunctioned.
• Li Yu killed a Quantum Phantom with Piercing Magic Bullet, and Herta discovered her magic defeated them far more effectively than her Path power.
• Herta led the group back through the passage to plan a larger route for the Astral Express or Abant and continue their research.

After the Astral Express reached Abant to help build a passage into the Sea of Quanta, Li Yu prepared defenses because the Corporation had likely discovered the star system. The Xianzhou forces mobilized, and Li Yu sent the Flugel and Ex-Machina to seal the system while the others prepared to retrieve the remaining people of Cangcheng.

• Herta and the other geniuses confirmed that time flowed normally between the Sea of Quanta and the outside, then began constructing a passageway.
• Li Yu asked Himeko to bring the Astral Express to Abant, and Pom-Pom piloted it there at full speed.
• Li Yu sent the Xianzhou generals coordinates and asked Feixiao to help seal the star system while he retrieved the other people of Cangcheng; the Marshal ordered Feixiao, Jing Yuan, and Yaoguang to mobilize.
• Li Yu proposed calling Lan, but the Xianzhou generals objected, so he instead told them the Flugel could unleash an Aeon-level strike.
• Li Yu ordered the Flugel and Ex-Machina to seal the star system and attack any ships that ignored their warnings.

Li Yu enlisted the Xianzhou generals and Qingque to help search the Sea of Quanta for Cangcheng’s missing people, while Herta and the researchers completed a massive star ring. The chapter ended as Li Yu and the others prepared to test the ring under the Xianzhou ships’ guard.

• The Xianzhou Yaoqing, Luofu, and Yuque sealed the star system while Li Yu explained his plan to find Cangcheng’s scattered survivors.
• Yaoguang and Feixiao offered diviners to aid the search, and Li Yu asked Jing Yuan to send Qingque because of her hidden ability to hit exact target scores.
• Jing Yuan agreed to lend Qingque but decided to train her as his successor, while the marshal ordered the generals to give Li Yu their full support.
• Qingque and the diviners arrived on the Abant as Herta and the researchers finished building a massive star ring with supplies from the Xianzhou ships.
• Herta brought Li Yu to test the star ring, and Lygus activated it while the Xianzhou crews stood ready for trouble.

Li Yu led Abant into the Sea of Quanta and began transforming it into a quantum life-form while the Astral Express laid a Star Rail into the new territory. The train joined Abant in the Sea of Quanta, where its Path power surged and Pom-Pom began strengthening it as Welt Yang returned to the place where he had once been imprisoned.

• The gate opened, and Li Yu led Herta and the others aboard Abant while Himeko prepared the Astral Express to follow.
• Li Yu sent Abant through the gate into the Sea of Quanta, where Pandora told him to absorb its energy and become a quantum life-form.
• Abant devoured quantum energy and began changing, while Ruan Mei monitored its transformation and Herta recognized the potential of the plan.
• The Astral Express laid a Star Rail through the gate, prompting the Corporation to seek talks with the Xianzhou, which rejected its request and sent the Marshal to protect the expedition.
• The Astral Express entered the Sea of Quanta, where its Path power surged and Pom-Pom converted the excess into fuel and reinforcements for the train.
• The Astral Express stopped beside Abant as the Star Rail continued extending, and Welt Yang was thrilled to return to the Sea of Quanta.

Li Yu and the others searched the Sea of Quanta for signals while the Astral Express explored its worlds. After locating two signals and sensing Asuna and the others in Teyvat, Li Yu went to join the Astral Express so he could bring them there and help his companions grow stronger.

• Li Yu completed Abant’s conversion into a quantum lifeform and ordered the Flugel and Ex-Machina to patrol for quantum phantoms.
• Li Yu, Herta, Screwllum, and the others used the Scepters of the Emperor to search the Sea of Quanta for Li Yu’s companions and Welt Yang’s home signal.
• Welt Yang discussed exploring the Sea of Quanta with Himeko, and the Astral Express began traveling along Pom-Pom’s Star Rail tracks.
• Li Yu sensed Asuna and the others, and Pandora helped the Scepter of the Emperor lock onto two signal directions.
• Li Yu left the library to find the Astral Express, intending to take it to Teyvat and help Asuna and the others advance along a Path.

Li Yu brought the Astral Express through the Sea of Quanta and into Teyvat to reunite with Asuna and his companions. The train arrived at the Jade Chamber, where Liyue’s leaders and adepti gathered as Li Yu stepped out.

• Li Yu asked the Astral Express crew to take him to Abant, and March 7th, Welt Yang, and Himeko agreed to go.
• Pom-Pom agreed to give Li Yu’s companions train tickets so they could follow the Path of Trailblaze.
• After traveling through the Sea of Quanta, the Astral Express entered the World Bubble containing Teyvat and headed toward Li Yu’s companions.
• The train passed through Teyvat’s false sky as its rulers watched without intervening, and Zhongli followed it toward Liyue Harbor.
• Asuna and the others flew to the Jade Chamber, where Ningguang asked whether the arriving train belonged to one of Asuna’s companions.
• The Astral Express stopped at the Jade Chamber, and Li Yu stepped out to reunite with his companions.

Li Yu and the Astral Express arrived in Liyue, where Ningguang and Zhongli questioned them about their origins and the newly opened passage between worlds. Li Yu reassured Zhongli that the wider worlds were unlikely to threaten Teyvat, but Zhongli still wondered whether he should flee with Liyue’s people.

• Pandora gave Asuna Yuuki and the Special Class cover identities as Xianzhou survivors, and they reunited with Li Yu and the Astral Express.
• Asuna Yuuki introduced Li Yu and his companions to Ningguang, Keqing, Ganyu, Lumine, and Paimon, and Ningguang invited them into the Jade Chamber.
• Zhongli revealed his true identity to Liyue’s leaders, while March 7th and Welt Yang discussed how Liyue resembled the Xianzhou and Shenzhou.
• Li Yu explained that the passage into the Sea of Quanta was sealed against outsiders, easing Zhongli’s fear that other worlds would invade Teyvat.
• Li Yu said a powerful Will encompassing many worlds was awakening, and Zhongli wondered whether to flee with Liyue’s people.

Li Yu explained that a vast will spanning many worlds would soon awaken in Teyvat, then led his companions on a tour of Liyue Harbor. Pandora confirmed their mission in Teyvat was complete, and the group prepared to leave for the Honkai: Star Rail world as Li Yu revealed he had reached rank eleven.

• Li Yu told Himeko, Welt Yang, and Zhongli that a will encompassing many worlds would soon awaken, and Zhongli wondered whether Phanes and the Four Shades already knew about it.
• After leaving the Jade Chamber, Li Yu's group toured Liyue Harbor, split up to avoid attention, and exchanged information through their magical marks.
• Li Yu assured Asuna and the others that Pandora would protect their identities, and Pandora confirmed Teyvat was ready and they could leave with him.
• Li Yu said the group would be able to board the Astral Express and follow a Path after returning, then revealed that he had reached rank eleven.
• Yukino considered having seven or eight children as a way to take revenge on Li Yu, while Xia Yu lamented that she could not keep up with his rapid growth.

Li Yu brought Asuna and his classmates aboard the Astral Express, where Pom-Pom let them step onto the Path of Trailblaze and they all advanced to the seventh tier. He planned to return to his world while Asuna and the others stayed in Teyvat, now able to keep in touch and travel via the star rail.

• Li Yu spent the night with Asuna and the others at their inn in Liyue, and Yukino fled to her room after he invited her to join them.
• Li Yu brought his classmates to the Jade Chamber and asked Pom-Pom to let them step onto the Path of Trailblaze.
• Pom-Pom checked their tickets, and Asuna and every other classmate advanced to the seventh tier.
• Xia Yu and the others planted Trailblaze Anchors inside the Astral Express, so Pom-Pom erased them and scolded the group.
• Li Yu told Asuna and the others that he would return to his world while they stayed in Teyvat, then gave them phones so they could keep in touch.

Li Yu and his companions gave out Star Rail phones before Pom-Pom helped Lumine recover her memories and sealed power by welcoming her onto the Path of Trailblaze. After sharing technology with Liyue’s leaders, the group returned to the Astral Express with a route back to Teyvat and Li Yu considered taking Trailblaze across more worlds.

• Li Yu reassured Xia Yu that the phones’ network was safe and gave Asuna a hundred phones to distribute.
• Asuna summoned Lumine to the train so Li Yu could help restore her missing memories.
• Pom-Pom stamped Lumine’s ticket, breaking her seal and returning her memories and strength as she resonated with the Path of Trailblaze.
• Asuna gave phones to Lumine and Paimon, while she also shared them with Ningguang and other Liyue leaders.
• Li Yu and the others departed after leaving a Trailblaze Anchor connected to the Star Rail in Teyvat.
• Li Yu wondered whether the Astral Express could travel across countless worlds and help the Path of Trailblaze encompass the multiverse.

Li Yu returned to Abant with the Astral Express and found that Herta had built a large laboratory using his materials. He gave Ruan Mei research materials from Teyvat and agreed to let Herta continue using his supplies, while Herta asked him for Dragonia scales after Jibril had refused her.

• Pandora told Li Yu she planned to give Abant the Path of Trailblaze so it could lay star rails and serve as an alternative Astral Express.
• Li Yu and the others returned to Abant, where they found Herta's rapidly built laboratory beside the vehicle.
• Herta asked whether Li Yu had found what she needed, and Li Yu explained that his companions had stayed behind after embarking upon a Path.
• Li Yu gave Ruan Mei crates of monster materials from Teyvat, and she took them away to research.
• Herta told Li Yu she had used his materials, including Dragonia scales, to build the laboratory, and he allowed her to keep using them.
• Herta asked Li Yu for more Dragonia scales and complained that Jibril had refused her request and nearly fought her.

Li Yu returned from the Sea of Quanta to confront the Company fleet pressing against the passage, while Himeko and the others set out to search for his companions. He ordered the Flugel to strike the Company warships, and their Divine Strike alarmed the fleet and the Company headquarters.

• Li Yu gave Herta a small piece of Dragonia scale, then resumed scanning the Sea of Quanta while Himeko and the others studied materials and planned their next exploration.
• Li Yu asked Himeko to search in the direction of newly detected signals for his companions, while he prepared to handle the Company and gather technology before returning elsewhere.
• After Herta completed her research institute, Li Yu left Abant and found the Company fleet advancing toward the passage guarded by Xianzhou ships.
