Chapter Summaries

Mei Chengyu recalled a childhood visit to Taiyi, where his father defended the Mechanism Clan and placed a glowing object in the Abyssal Sea. Back in the present, Mei Chengyu used his Mystic Technique to protect Xing Chun and Zhongli Shan as the sea eye dragged them toward the seabed, while Yu Sui learned that the missing Milky Way Water was hidden there and Cao Yan departed Taiyi.

• In a dreamlike memory, Mei Chengyu saw his father tell the Four Great Mechanical Clans that the Xuangu Continent could not survive without the Mechanism Clan and that he would handle the Yan Kingdom's troubles himself.
• Mei Chengyu remembered diving with his father and brother, finding Six Mysterious Wood beneath the Red Coral, and watching his father drop a glowing object into the sea eye.
• Mei Chengyu woke inside the sea eye, used the Mystic Technique to resist its chaotic Five Elements Qi, and pulled Xing Chun and Zhongli Shan close as it swept all three toward the seabed.
• Yu Sui questioned Cao Yan about Xuan Kui, Nian Qiuyan, and the Lan Poison, and Cao Yan told her that Nian Qiuyan had revealed the Milky Way Water was hidden in the Abyssal Sea with Six Mysterious Wood.
• Cao Yan told Yu Sui he was leaving Taiyi the next morning and said Zhang Xiangyun would find a way to retrieve the Milky Way Water.
• Yu Sui went to see Cao Yan off, and he left wondering how she had become more composed since arriving in Taiyi.

Yu Sui reflected on the dangers and uses of Lan Poison, then returned to her studies and sword training while keeping her worries about Nian Qiuyan to herself. The chapter ended with her discovering that Mei Liangyu was far out at sea.

• Nian Qiuyan told Zhang Xiangyun he had no reason to visit Mechanism Island, and Zhang Xiangyun arranged a time to retrieve the Milky Way Water.
• Yu Sui received the academy's notice that a Sage had destroyed the Lan Du Organization, while the academy withheld information about the Milky Way Water.

• Yu Sui checked Mei Liangyu's location on the Listening Wind Ruler and found that he was far out at sea.

Yu Sui lost contact with Mei Chengyu after the Communication Institute suspended the Listening Wind Ruler for seven days to inspect its Number Mountains. Zhang Xiangyun confronted her about the Milky Way Water and forced her and Li Jinshuang to agree to go to Mechanism Island, where Yu Sui’s dangerous involvement with Zhang Xiangyun remained unresolved.

• Yu Sui saw Mei Chengyu’s location disappear from Taiyi’s map, and the Communication Institute announced that all Listening Wind Ruler functions would be suspended for seven days.

• Yu Sui took Li Jinshuang to her dormitory, explained her relationship with Zhang Xiangyun, and shared her fears about the dangerous mission.
• Li Jinshuang reassured Yu Sui that she did not see her as someone who would become like Zhang Xiangyun, and the two shared the late-night snacks.

Yu Sui and Li Jinshuang watched the Abyssal Sea’s sea eyes move, merge, and appear as the group searching for the Milky Way Water went underwater. When one swallowed Luo Fu’s Lightning Summoning Formation, representatives of the Four Great Mechanical Clans and several schools arrived at the shore.

• Aboard Zhang Xiangyun’s private boat, Yu Sui told Nian Qiuyan she would try to recover the Milky Way Water if Mei Chengyu had taken it, while Zhang Xiangyun questioned her plan.

• Yu Sui and Li Jinshuang climbed to a cliff and saw numerous sea eyes moving and merging, while new sea eyes formed across the sea.
• A sea eye appeared near shore, swallowed Luo Fu’s Lightning Summoning Formation, and vanished as the storm intensified.
• Yu Sui and Li Jinshuang saw practitioners from the Wen Yang, Situ, Murong, and Baili families arrive, followed by the Academy Saint, Leng Rouyin, Ou Rushuang, and Wu Huaiwei.

Yu Sui overheard the Academy Sages and Mechanism Clan discussing the Sea Eyes spreading through the Abyssal Sea, while their rivalries and hidden agendas surfaced. As the clans began preparing a barrier and the Sages worked to stabilize the Five Elements Qi, Yu Sui and Li Jinshuang worried about people still missing beneath the sea.

• Wu Huaiwei revealed that the Sea Stabilizing Pearl could no longer suppress the Abyssal Sea's chaotic Five Elements Qi, and she challenged Leng Rouyin over the Sea Eyes and the Water Vessel Plan.
• Situ Jin told the Sages that the Murong and Baili Families were preparing the Muti Water Wall, while the other clans would help stabilize the sea and clear a path for the formation.
• The Sages used Sea Stabilizing Pearls to suppress the Five Elements Qi as the clans sent boats into the storm to mark out the Muti Water Wall.
• Yu Sui overheard Wen Yangzhou and Wen Yangxiu worrying that Meimei might be in the sea, and the brothers argued over who should investigate the Undersea Mechanism City.
• Yu Sui and Li Jinshuang discussed the Sea Eyes and the possible origin of Milky Way Water, while Li Jinshuang worried that Zhang Xiangyun and the others might return from beneath the sea in front of everyone.

Yu Sui and Li Jinshuang disguised themselves as Wen Yang Family Technicians and sneaked onto a giant ship bound for the Undersea Mechanism City. While hiding aboard, Yu Sui discovered that Lin Chenghai had possessed Wen Yangzhou and planned to use the Sea Eye to take a missing Young Master away from Taiyi, leaving her worried that the impostor would recognize her.

• Yu Sui decided to search underwater for Mei Chengyu, and Li Jinshuang joined her; they knocked out two Wen Yang Family Technicians and stole their clothes.
• Yu Sui and Li Jinshuang boarded the giant ship in disguise and were ordered to hang coins in the Golden Sea Conches used to detect the Sea Eye.
• Yu Sui followed Wen Yangzhou with a Five Elements Light Core and watched a middle-aged man and Lin Chenghai trap and possess him.
• Lin Chenghai and Hu Gui said their Young Master had disappeared in the Abyssal Sea, suspected he had been swept into the Sea Eye, and planned to replace the Undersea Mechanism City's Central Hub to take him away from Taiyi.
• Yu Sui realized the possessed Wen Yangzhou could access his memories and worried he would recognize her as he and Hu Gui approached her level of the ship.

Yu Sui and Li Jinshuang secretly boarded the Spirit Bird as the Mechanism Clan set sail for the Undersea Mechanism City. After the ship dived beneath the sea, Yu Sui spotted Zhang Xiangyun and his companions approaching and used water arrows to drive Zhang Xiangyun and Luo Fu away.

• Yu Sui and Li Jinshuang avoided discovery when a man posing as Wen Yangzhou entered the room where they were working on the Water Control Mechanism.
• The Spirit Bird set sail with stewards from four Mechanism families and Ou Rushuang aboard, then crossed the Muti Water Wall into the stormy Abyssal Sea.
• The Mechanism Clan used Golden Sea Conches, formations, and the Golden Crow to stabilize the sea and complete Sea and Sky in One Color, allowing the Spirit Bird to dive beneath the surface.
• Situ Jin left the Helm Station to inspect the Observation Deck while the Spirit Bird headed toward the Undersea Mechanism City.
• Yu Sui spotted Zhang Xiangyun, Luo Fu, and Nian Qiuyan approaching the Spirit Bird and sent water arrows that wounded Zhang Xiangyun and Luo Fu, forcing them to retreat.

• Zhang Xiangyun and Luo Fu treated their injuries while Nian Qiuyan warned them that the Spirit Bird likely carried Mechanism Clan members and Academy Saints.
• Yu Sui and Li Jinshuang hid behind discarded Mechanism Boxes as Lin Chenghai, disguised as Wen Yangzhou, went with Situ Jin to observe the expanding Sea Eyes.
• Ou Rushuang questioned Situ Jin about the Undersea Mechanism City and recognized Lin Chenghai's disguise when the Golden Butterfly appeared.
• Lin Chenghai tore off his bandage and fought the Golden Butterfly with Five Elements Qi, while Hu Tao grabbed Situ Jin by the throat and took him hostage.

Yu Sui and Li Jinshuang were caught between Ou Rushuang, Lin Chenghai, and Hu Gui as their techniques and poison creatures turned the passage into a battlefield. Hu Gui escaped with Situ Jin, while Ou Rushuang revealed that Lin Chenghai had inherited the Blood Jade Golden Butterfly’s poison and was beginning to succumb to it.

• Ou Rushuang recognized Lin Chenghai’s Buddhist School Stealing Soul, Changing Corpse technique and attacked him with the Blood Jade Golden Butterfly.
• Ou Rushuang pursued Hu Gui, who used the Ghost Dao School Life Talisman to threaten Situ Jin and force Ou Rushuang back.
• Yu Sui warned Hu Gui about a Praying Sky Spider, but Hu Gui drained its vitality; Ou Rushuang then revived the dead Poison Beasts with Five Elements Qi.
• Li Jinshuang and Yu Sui dodged the butterflies and spiders as Hu Gui sealed Situ Jin’s mouth, then blew open a wall and escaped with him.
• Lin Chenghai drove Ou Rushuang toward the passage entrance, but Ou Rushuang revealed that the butterfly’s poison had transferred to Lin Chenghai through his possession technique.

Yu Sui helped the injured Lin Chenghai evade Ou Rushuang aboard the Spirit Bird and persuaded him to cooperate in finding their companions. Lin Chenghai learned she was the Ghost Dao Sage’s other disciple, while Yu Sui remained unaware that her naïveté was exasperating him.

• Lin Chenghai summoned a Wrathful Vajra to fight Ou Rushuang, then used Dubu to escape while the Vajra delayed Ou Rushuang and shattered the nearby passageways.
• Yu Sui followed the wounded Lin Chenghai to the Herb Garden and gave him an Instant Concealment Talisman as Ou Rushuang arrived.

• Yu Sui told Lin Chenghai that Wen Yangzhou was a friend of her Senior Martial Brother and asked him to help find their companions; Lin Chenghai agreed that he had no reason to kill Wen Yangzhou.
• Lin Chenghai asked Yu Sui to reveal her identity, and she explained that she was the Ghost Dao Sage’s only other disciple before absentmindedly realizing she had given away too much.

Yu Sui rescued the wounded Lin Chenghai and persuaded him to help her find Mei Chengyu in Undersea Mechanism City. They reached the Spirit Bird’s third underground level, where Lin Chenghai warned her that Ou Rushuang’s search would make it difficult to stay hidden.

• Lin Chenghai demanded that Yu Sui reveal her face, then recognized her as a likable disciple and asked her to gather Hemostasis Pills.
• Yu Sui told Lin Chenghai she and her Senior Martial Brother were in love and insisted she would search for him even inside a Sea Eye.
• Yu Sui hid her name and asked Lin Chenghai to help her find Mei Chengyu, and he agreed while warning that she was not strong enough to search alone.
• Yu Sui used Five Elements Light Cores to scout as Lin Chenghai guided her through the Spirit Bird to a Ship House on the third underground level.
• Lin Chenghai warned Yu Sui that Ou Rushuang had ordered the Mechanism Technicians searched and guarded the exits against Instant Concealment Talismans.

Yu Sui and Lin Chenghai traveled aboard the Spirit Bird toward the Undersea Mechanism City while dodging detection and discussing the Sea Eyes. They reached North Kun City, a vast city built across the tail of a giant whale, as Yu Sui reflected on the Mechanism Clan’s decline.

• Lin Chenghai used Vajra Body to restrain the Blood Jade Golden Butterfly’s poison, then warned Yu Sui not to risk entering a Sea Eye.
• Hu Gui hid with Situ Jin while Li Jinshuang pursued them, and they jointly destroyed a Mechanism Dragonfly before escaping in different directions.

• The Spirit Bird reached the seabed and revealed North Kun City, a monumental Mechanism Clan city built across a giant whale’s tail.

Lin Chenghai took Yu Sui into North Kun City and explained its history, the sea eyes, and Shuizhou’s experiments to create them. A deep bell rang through the city, and Lin Chenghai realized the people who had arrived by ship were already searching for them.

• Lin Chenghai brought Yu Sui beneath the Spirit Bird in Floating Light bubbles and guided her to the Jade Tree at North Kun City’s edge.
• Lin Chenghai explained that the Gongshu Clan built the First Generation Golden Crow and that North Kun City became Taiyi’s underwater mechanism site after the Mechanism Clans were hunted.
• Yu Sui asked about the sea eyes, and Lin Chenghai described how Shuizhou’s Sages studied creating them to seek Guixu and destroy the strange fires.
• Yu Sui asked whether Sage Chang Gen knew about Guixu, but Lin Chenghai mocked her for not knowing how long her own Master had lived.
• A deep bell rang through North Kun City, and Lin Chenghai said the newcomers were already searching for people.

Situ Spirit Puppet and Baili Mo arrived in North Kun City, where a strange Sea Eye had destroyed part of the city and left behind fire that devoured Five Elements Qi. As the newcomers investigated and Ou Rushuang pursued the missing Milky Way Water, Xing Chun remained trapped underground with his two unconscious companions.

• Situ Spirit Puppet used the golden bells to locate Situ Jin and Wen Yangzhou, then sent her people after them while Baili Mo went to investigate the damage.

• Xing Chun kept watch in the underground Panlong Stone Grotto as his poisoned and exhausted companions remained unconscious, and he resolved to stay alive long enough to collect their bodies.

As Mei Chengyu lay unconscious, he relived Gao Tianhao’s memories of helping a young son of the Eldest Princess secretly heal Yan’s Sixth Prince. The memories ended with Gao Tianhao leaving Yan Capital before the boy’s father returned, a decision he later regretted.

• Xing Chun kept watch over Mei Chengyu and Zhongli Shan while Mei Chengyu heard his voice and drifted through chaotic memories.
• Mei Chengyu witnessed the boy recruit Gao Tianhao to heal the Sixth Prince’s injured soul and restore his lost memories.
• Gao Tianhao secretly treated the Sixth Prince for months while the boy concealed their efforts amid Yan Capital’s political turmoil.
• When Nangong Ming arrived in Yan Capital, the boy sent Gao Tianhao away through a secret passage before the capital was searched.
• Years later, Gao Tianhao saw the boy again in Taiyi and wondered whether staying in Yan Capital would have changed what happened.

Mei Chengyu’s sealed memories stirred as the sea eyes around Mechanism Island vanished, while Wen Yangxiu learned that a sea eye had struck North Kun City. In North Kun City, Yu Sui separated from Lin Chenghai and, after seeing signs of the attack through the Five Elements Light Cores, set out to find a way underground.

• Mei Chengyu’s memories of his family, Gao Tianhao, and Yu Sui surfaced, and hatred stirred a vortex in the depths of the sea.
• Leng Rouyin and Wu Huaiwei saw the sea eyes shrink and disappear, leaving one enormous sea eye and chaotic Five Elements Qi behind.
• Wen Yangxiu decoded a message from Baili Mo reporting that a sea eye had fallen on North Kun City, and Leng Rouyin decided to investigate the Undersea Mechanism City at daybreak.
• Wu Huaiwei provoked Leng Rouyin with talk of strange fire, prompting Leng Rouyin to attack her with Sword Qi before returning to confer with the other Sages.
• In North Kun City, Lin Chenghai parted from Yu Sui and told her to look underground for Wen Yangzhou while he went after the First Generation Golden Crow.
• Yu Sui saw Baili Mo enter the smoke and Nian Qiuyan locate Mei Chengyu through the Five Elements Light Cores, then believed Lin Chenghai and began searching for an underground route.

Yu Sui searched for a way into North Kun City's underground while Zhang Xiangyun and Luo Fu hunted for Mei Chengyu amid the Sea Eye's deadly flames. They opened a secret warehouse and found hundreds of lifelike Situ Clan Spirit Puppets suspended by silver threads.

• Yu Sui tested the Sea Fire with a Five Elements Light Core, then used her cores and a map to find an underground entrance while tracking Lin Chenghai.
• Baili Mo rang the Sound Seeking Golden Bell, but it could no longer locate Situ Jin or Wen Yangzhou.

• Zhang Xiangyun and Luo Fu entered a secret warehouse behind a screen and opened its Stone Door cautiously.
• Zhang Xiangyun, Luo Fu, and Yu Sui saw hundreds of faceless, lifelike Situ Clan Spirit Puppets hanging from silver threads, and Zhang Xiangyun realized the warehouse's wards had been removed.

Hu Gui attacked Zhang Xiangyun and Luo Fu in the Spirit Puppet Deep Pit, but Li Jinshuang, Situ Jin, and Yu Sui disrupted his plans. Luo Fu used Lotus Mist to recover his strength and stood ready to rejoin the fight.

• Hu Gui immobilized Luo Fu with the Seven Consciousness Tower and attacked Zhang Xiangyun, who survived with the Divine Wood Sign’s blessing.
• Hu Gui’s sword awakened Li Jinshuang’s enormous White Bone Sword Spirit, which freed Li Jinshuang and helped her release Situ Jin.

In a passage, Yu Sui discovered that she could immobilize Situ Spirit Puppet by disrupting the power inside her, while Hu Gui escaped through a hidden door with a spirit puppet and Situ Jin pursued him.

• Luo Fu unleashed Heavenly Dipper Earthly Fiend Thunder, forcing Hu Gui to retreat as Zhang Xiangyun prepared another formation and Li Jinshuang’s sword spirit attacked indiscriminately.
• Yu Sui sensed someone ahead in a dark passage and was attacked by Situ Spirit Puppet, who used Shadow Devouring and asked whether Yu Sui belonged to the Wen Yang Family.
• Yu Sui used Spirit Siphon and shattered the Five Elements Light Core attached to Situ Spirit Puppet, causing conflicting Qi to freeze the puppet in place.
