Li Yu met Ichiryu and learned that Gourmet Cells depended on ingredients for replenishing energy, then returned to his world with contact phones for cooperation. After discussing the risks and opportunities with Nangong Natsuki and the others, they agreed to let people choose whether to obtain Gourmet Cells and report the policy upward.

Li Yu learned from Asuna that the Konosuba world offered easy skill learning, levels, and potentially useful cheat abilities, making it valuable for training newcomers. He planned to investigate it and began assembling a team, leaving with Tendō Kisara and Miori Shiba as he arranged for the others to join them.

• Li Yu contacted Asuna, who described the Konosuba world and said the group had chosen classes to learn its skills while searching for cheat abilities and divine artifacts.
• Li Yu decided to visit the world, then told Nangong Natsuki that it could be used to train newcomers and asked to take a team there.
• Nangong Natsuki approved the plan, and Li Yu selected Sakayori Iroha, Tendō Kisara, Miori Shiba, and two additional students for the five-person team.
• Li Yu messaged Zhang Li to arrange the remaining team members, then went to Tendō Kisara and Miori Shiba's classroom to collect them.
• Li Yu showed the teacher his identification, requested leave for the two girls, and transported them away with a purple Magic Array.

Li Yu brought Miori Shiba, Tendō Kisara, Eriri, and Yuki Suou to Boundary University so Hestia could give them Falna before he took them to another world. While waiting, he discovered that Da Vinci had transformed the library into the core of a spreading magic array, but Hestia did not know what Da Vinci and Morgan were planning.

• Li Yu met Sakayori Iroha, Eriri, and Yuki Suou outside the classroom and learned that Eriri had been away and Yuki had recently joined the class.

After reuniting with Asuna’s group, Li Yu removed the soul binding from a divine artifact Asuna had bought from Kazuma and decided to use it as material for new Noble Phantasms.

• Li Yu decided to melt down the divine artifact and use its materials to forge Noble Phantasms for Kato Megumi and Yukino Yukinoshita.

Li Yu took Asuna and the others to meet Wiz, a powerful lich who was starving because she spent her money on useless magical items. After feeding her, they asked her to teach them magic and planned to test whether learning spells could change their attributes or magical aptitude.

• Asuna and the others registered at the Guild, and Li Yu suggested learning advanced spells from Wiz instead of copying Asuna's low-level magic.
• Li Yu revealed that Wiz was a powerful lich who was nearly starving, so Mahiru Shiina packed food and the group headed to her shop.
• At Wiz's shop, Mahiru gave Wiz the food, and Wiz devoured it before asking how she could repay them.
• Li Yu offered to pay Wiz ten thousand Eris per spell, but Wiz refused the money and offered to teach them as repayment for the meal.

Li Yu and the others learned spells from Wiz, and Li Yu let her use Mana Drain so he could study the lich ability. After paying Wiz and leaving her shop, the group headed outside the city to test whether learning new spells had given them additional magic attributes.

• Asuna offered Wiz money, and Li Yu and the others left after Wiz thanked them and offered future help.
• Li Yu led the group toward the outskirts of the city to test for new attributes and teach them simple attribute spells.

• Li Yu taught Beginner Magic to the group, and Sakayori Iroha learned the spells immediately, while Miori Shiba, Tendō Kisara, and Eriri explained their existing attributes and abilities.
• Yuki Suou said she had learned magic through an unusual energy, and Yukino Yukinoshita and Asuna demonstrated that learning magic had given them new elemental attributes.

• Li Yu explained to Eris that their worlds were inevitably connecting and promised that they could coexist as equals.
• Li Yu introduced himself to Eris and asked her to take him to the divine realm, offering to meet another goddess instead if she did not want a God Slayer there.

Li Yu and Eris reached a verbal agreement allowing travel between their worlds, with the goddesses asking him to eliminate the Demon King and recover Aqua’s lost items. After returning to Asuna and the others, Li Yu realized Eriri’s magic-copying talent resembled Principal Hu’s and warned her about the dangers of copying non-human magic.

• Eris told Li Yu that the goddesses would accept his plans for cooperation as long as he avoided large-scale slaughter, and asked him to defeat the Demon King and recover Aqua’s belongings.
• Li Yu agreed to the goddesses’ conditions, and Eris asked what rules would apply if she visited his world before returning to report their discussion.
• Li Yu told Asuna and the others that the goddesses did not care much about their world and had placed no conditions on travel between the worlds.
• Li Yu noticed that Eriri’s Magic Profiling talent resembled Principal Hu’s Magic Echo and called her group over to discuss it.
• Sakayori Iroha recalled the warning in Magic Fundamentals against learning other races’ magic, and Li Yu began explaining why it mattered to Eriri.

Li Yu warned Eriri not to copy unfamiliar magic, then returned from the other world and sent Zhang Li and the remaining Special Class students there to train. Back in his dorm, he failed to reach the tenth rank with Ninefold but realized parallel worlds might offer a way forward.

• Li Yu explained that copying Dragon Race magic had ruined Principal Hu’s ninth-rank strength, and warned Eriri not to copy unfamiliar magic even from apparent humans.
• Sakayori Iroha confirmed that killing monsters had increased their experience, and Li Yu told the group to keep leveling in that world while he returned home.
• Li Yu suggested that Asuna lead the group against the Demon King, and Asuna agreed to pursue the fight and earn achievements.
• Li Yu returned to the Gourmet World base, explained the other world to Nangong Natsuki, and agreed to send the new Special Class there to train.
• Li Yu sent Zhang Li and the remaining students to join Asuna’s group, then returned to his dormitory and tried using Ninefold to break through to the tenth rank.
• Li Yu’s attempt only raised his attributes, but his talent led him to wonder whether another parallel version of himself existed.

Li Yu reconstructed his former self’s Sacrifice talent and altered it to summon and fuse all his parallel-world selves, converging them into one timeline. This gave him a path toward a time-and-space law for reaching the tenth rank, and he then joined Pandora as she drained the Root while Gaia and Alaya were restrained.

• Li Yu found the Sacrifice talent hidden in his soul and analyzed how it summoned the version of himself with the greatest potential.
• Li Yu removed the talent’s sacrificial cost and used it to pull in and fuse his parallel-world selves, causing their worldlines and traces to disappear.
• Pandora noticed Li Yu’s convergence, judged it a strong foundation but insufficient for a tenth-rank breakthrough, and left to target Gaia and Alaya over secrets in the Root.
• After fusing his selves, Li Yu realized he would need to master time and space, then saw Pandora’s message asking him to come to her.
• Li Yu washed up and entered the Type-Moon world, where he found Pandora absorbing the Root and Gaia and Alaya imprisoned and injured.

Li Yu learned the Fifth Magic from the Root while Pandora prepared to absorb the Nasuverse and warned him about a powerful world hidden beyond it. At Pandora’s request, he took the defeated Gaia and Alaya to his world and confined them in the Throne of Heroes.

• Pandora found a passage in the Root to an exceptionally powerful world, and Li Yu used the Root to master the Fifth Magic.
• Pandora told Li Yu that beings in the hidden world could destroy a universe and that he should not enter it yet.
• Pandora explained that she was absorbing the Root and taking over from Gaia and Alaya, so she asked Li Yu to bring them back to her world.
• Li Yu carried the immobilized Gaia and Alaya away from the Nasuverse while Pandora threatened to beat them again later.
• Li Yu brought Gaia and Alaya to the Throne of Heroes, where their restraints disappeared but a stronger confinement held them there.

Li Yu returned to Abant to study the Dragonia scales and combine his mastery of space with the Fifth Magic of time. His experiments began distorting space and time around Abant, leaving Nangong Natsuki and Jibril wondering whether the Dragonia were attacking.

• Li Yu told Gaia and Alaya that other worlds would not resist Pandora, then left them imprisoned in the Throne of Heroes.
• Gaia and Alaya argued and grappled while the Heroic Spirits celebrated their freedom under Pandora's contracts and left the Throne.
• Li Yu returned to Abant, told Think he planned to break through, and took Dragonia-related items from the vault to begin secluded cultivation.
• Li Yu studied the Dragonia scales on Artosh's throne and began combining his spatial abilities with the Fifth Magic's power over time.
• Li Yu's growing power distorted space and time across Abant, slowing and freezing Think as he experimented with stopping time.
• Nangong Natsuki noticed Abant's strange space, and Jibril returned and suspected that the Dragonia were attacking.

Li Yu’s breakthrough at Abant unleashed a chaotic temporal-spatial barrier that the Flugel guarded while Boundary Island kept people away. After time passed differently inside and outside, Li Yu emerged having reached Rank Ten and discovered a path forward through time and space, karma, fate, and chaos.

• Nangong Natsuki and Jibril recognized Li Yu’s aura above Abant and realized he was breaking through, so they arranged to keep the airspace clear.
• Jibril summoned the Flugel, who sealed off the sky and guarded the spreading temporal-spatial barrier while Principal Hu and the others watched from afar.
• The barrier expanded until midnight, then contracted by dawn, and the Flugel found Think waiting inside Artosh’s palace.
• Think told Jibril that she had experienced seven days inside Abant while only one night had passed outside.
• Li Yu opened his eyes after breaking through and realized his future path lay through mastering time and space, cycling karma, establishing fate, and transforming everything into chaos.

After breaking through to the tenth rank, Li Yu explained laws and the paths to further advancement to the Flugel. He left Artosh’s Law of War in the palace for them to study, while Think began to grasp how laws related to magic.

• Li Yu emerged from the palace, reassured the Flugel that the disturbance had been caused by his breakthrough, and answered Think’s questions about the level beyond the Ninth Tier.
• Li Yu explained that reaching the tenth rank required grasping a law, and distinguished world-bestowed laws from laws a person condensed themselves.
• Li Yu showed the Flugel Artosh’s Law of War and explained that it suited their race but would lead them only as far as Artosh.
• Little Jibril rejected following Artosh’s path, while Li Yu placed the Law of War in the palace for the Flugel to study.
• Think reasoned that magic relied on the world’s laws and that mastering a law would let someone use it instinctively; Jibril began considering the idea too.

Li Yu returned from Abant after helping the Flugel and Think consider how to grow stronger, then learned that Nangong Natsuki had arranged trade and development between connected worlds. He traveled to Totsuki Academy to take Erina to a training program, startling her and her secretary by appearing and passing through walls.

• Li Yu left the Flugel and Think to ponder his advice, then appeared before Nangong Natsuki and revealed that he had reached the tenth rank.
• Nangong Natsuki told Li Yu that IGO had arranged to trade ingredients and cultivate them in their world, and that Hiratsuka Shizuka had gone to Asuna's world to help prepare it as a beginner village.
• Nangong Natsuki asked Li Yu to bring Erina to the neighboring world for one of the training slots she had promised.
• Li Yu arrived at Totsuki Academy, saw that its back mountain had been turned into a plaza around the spatial passage, and found Erina in her room.
• Erina screamed when Li Yu appeared, and her secretary collapsed in fright after seeing him pass through the door like a ghost.

Li Yu took Erina, Hisako Arato, and Alice to the fantasy world, where they chose classes and received Falna so they could grow stronger. He then teleported them to Asuna and the others near the front lines, where a warning spell alerted the group to their arrival.

• Li Yu told Hisako Arato to pack her things and bring Alice, then took all three women from Erina's home to the fantasy world.
• Li Yu led Erina, Hisako Arato, and Alice to the Guild, where Erina chose mage, Hisako Arato chose knight, and Alice chose warrior.
• Li Yu bestowed Falna on the three women so they could gain strength through battle.
• Li Yu teleported the three women to Asuna's location, where Sakayori Iroha's warning spell reacted and the group raised their weapons.

Li Yu appeared at the camp after breaking through to rank ten and later used his new control over space-time to expand Betty’s library. He moved it into Abant and opened a passage to Boundary University’s library, where he found Da Vinci and several C-rank Heroic Spirits.

• Li Yu brought Erina and the other chefs to the camp, where Yuki Suou took them to help prepare food.
• Asuna, Kato Megumi, and Yukino Yukinoshita noticed Li Yu’s faint presence, and he revealed that he had broken through to rank ten.
• Li Yu learned that Xia Yu and the other students were scattered around the world collecting Aqua’s cheats, then left with Asuna after sharing a meal.
• Li Yu used his Law of Space-Time to enlarge and strengthen Betty’s library, adding changing scenery outside it.
• Li Yu and Betty moved the library into Abant and opened a passage to Boundary University’s library, where Li Yu found Da Vinci among several C-rank Heroic Spirits.

Li Yu helped Da Vinci and Principal Hu raise Boundary Island into a floating fortress, then learned that a sealed dimensional passage beneath the island connected to a powerful world. He grew curious about that world and suspected it might be connected to A Certain Magical Index.

• Da Vinci told Li Yu she planned to transform Boundary Island into a mobile fortress, and Principal Hu explained that he had approved the plan.
• Principal Hu revealed that another world lay beyond a sealed passage beneath the island and had supplied technology and influenced the talents people awakened.
• Li Yu poured magical power into Da Vinci's array, activating patterns that spread across Boundary Island and lifted it into the air.
• Li Yu sensed the passage beneath the sea, and Principal Hu warned that visiting the world beyond it required permission because it was dangerous.
• Li Yu wondered whether the other world was A Certain Magical Index and whether its Magic Gods, espers, and powerful figures were involved in its agreement with Pandora.

Li Yu learned that Pandora was preparing to match the Demon Gods’ power after absorbing the world, and she sent him to visit the world of A Certain Magical Index. He reached the sealed underwater facility beneath Boundary Island and found a laboratory hall containing a dimensional entrance and strange artifacts.

• Li Yu suspected Pandora had allied with Aleister and helped establish the supernatural abilities in this world, while Principal Hu said Pandora handled contact with the other world.
• Principal Hu assured Li Yu that supplies and freshwater would not be a problem when Boundary Island rose into the sky, and Li Yu agreed to help power its ascent.
• Li Yu told Da Vinci and the other Heroic Spirits that he had brought Betty’s library from Abant, and they rushed through the passage to explore it.
• Pandora told Li Yu she would soon become as strong as the Demon Gods after absorbing this world and instructed him to tell the upside-down man that she was nearly ready.
• Li Yu entered the underwater facility beneath Boundary Island, found a modern laboratory hall with a sealed dimensional entrance, and saw strange artifacts including an arm.

Li Yu entered the world of A Certain Magical Index and met Aleister, who asked him to teach Touma Kamijou a way to protect himself. Li Yu agreed, hoping the arrangement would also let him meet Index.

• Li Yu examined a mysterious arm in a glass case, then entered the world of A Certain Magical Index through the Dimensional Rift.
• Awaki Musujime met Li Yu in the Windowless Building and told him that Aleister wanted to see him, but Li Yu went directly to Aleister himself.
• Aleister and Aiwass discussed Li Yu's power, and Li Yu delivered Pandora's message that she would soon be able to deal with the Demon Gods.
• Li Yu explained that he had come to explore the world, and Aleister asked him to teach his friend Touma Kamijou how to protect himself.
• Li Yu agreed to teach Touma, partly because he hoped the arrangement would help him meet Index.

Li Yu settled into Academy City and was assigned to instruct Kamijou Touma in a sanctioned experiment. After discovering Touma’s Imagine Breaker and meeting him, Li Yu explained the arrangement, and Touma asked when the experiment would begin.

• Aleister gave Li Yu identity documents, money, and an apartment, then discussed his potential with Aiwass and suggested he meet Kamijou Touma.
• Li Yu explored Academy City, discovered that it had built Gundam-like mecha for space exploration, and copied their data.
• Li Yu moved into the apartment beside Touma’s and considered teaching him physical training techniques that Imagine Breaker could not erase.
• When Touma returned home, Li Yu passed through the wall, introduced himself as his neighbor and instructor, and showed him the experiment paperwork.
• Touma verified the experiment on Academy City’s website, received a delayed text confirming it, and asked Li Yu what he needed to do and when they would start.

Li Yu taught Kamijou Touma a breathing technique to improve his physical abilities and prepared a weakened Gourmet Cell serum for him. After three days of training, Li Yu returned to Touma to begin testing the serum.

• Li Yu taught Kamijou Touma a breathing technique and told him to practice at home for three days.
• Kamijou Touma felt strength fill his body after completing a breathing cycle and eagerly took leave from school to train.
• Aleister told Aiwass that Imagine Breaker had been traded to Pandora and that Touma becoming stronger would benefit them.
• Li Yu obtained Gourmet Cells from Nangong Natsuki and used a laboratory arranged by Aleister to make a serum that could raise physical abilities to Level 4, with Level 5 possible through training.
• Li Yu returned to Kamijou Touma after three days of practice and prepared to test the serum on him.

Li Yu gave Kamijou Touma a serum that strengthened his body, then brought him to Tokiwadai Middle School for testing. As the tests began, Li Yu noticed Shokuhou Misaki did not recognize Touma and planned to test Imagine Breaker himself later.

• Li Yu gave Kamijou Touma an enhancement serum, which caused intense heat and hunger as it strengthened him.
• Touma ate five servings of food, discovered his new strength when he slammed a door shut, and survived Li Yu throwing him from the fifth floor.
• Li Yu contacted Aleister, who directed him to take Touma to Tokiwadai Middle School for testing.
• Tokiwadai's principal welcomed Li Yu and arranged tests on the athletic field while Misaka Mikoto, Shokuhou Misaki, Shirai Kuroko, and Hokaze Junko watched.
• Li Yu saw that Shokuhou Misaki looked at Touma with unfamiliarity and planned to test Imagine Breaker himself.
