Highlights
Chen Changsheng awakens after 30 years of sleep, gaining lifespan and attribute points from his immortality system. He returns a defective coffin to Li the Cripple, who recognizes him despite his unchanging appearance. Learning that his beloved Nianci is ill, he searches for her, recalling his forced sleep due to war and his unique system that grants him immortality through slumber.
Nianci, ill and aged, reunites with Chen Changsheng, entrusting her son Niansheng to his care before she passes away. Five years later, Li the Cripple also dies, leaving his coffin shop to Chen Changsheng. Eight years after that, Niansheng grows up and is about to marry, leading Chen Changsheng to reflect on his loneliness and the fleeting nature of mortal lives.
Niansheng expresses her love for Chen Changsheng and decides to pursue cultivation to achieve immortality, hoping to stay with him forever. Chen Changsheng encourages her, emphasizing that he will always be there for her. He then begins cultivating in a coffin, utilizing the insights from the Blood Demon Ancestor's mixed five-elemental spiritual root to improve his own.
Fifty years later, Chen Changsheng arrives at Linglong Sect, where Niansheng has become the Immortal Fairy. He takes over a coffin shop nearby. Niansheng, now a Golden Core cultivator, still holds onto a wooden carving he gave her, suggesting her continued affection. Chen Changsheng uses an ancient bronze palace to advance his own spiritual roots.
Niansheng becomes an elder of Linglong Sect, while Chen Changsheng's suspicion grows regarding a traitor within their ranks. He discovers that the Blood Demon Ancestor's method of improving spiritual roots is indeed viable. The Night Moon Demon Kingdom attacks, prompting Niansheng to go to the front lines. Chen Changsheng decides to infiltrate the Night Moon Kingdom to recover his master's body, which has been turned into a puppet.
Chen Changsheng encounters the Demon King's daughter, Yue'er, and forms a disguise to participate in a marriage recruitment event. He uncovers the Demon King's plan to break through to Nascent Soul using ominous power from an ancient bronze palace and identifies his grandmaster, Yu Hua Zhenren, as the traitor who betrayed their sect.
Chen Changsheng confronts his grandmaster, Yu Hua Zhenren, the true mastermind behind the exploitation of the ominous power. He reveals his purpose is to reclaim the bodies of his master and senior brothers. Despite his grandmaster's power, Chen Changsheng's defense, amplified by his system, allows him to withstand attacks. Niansheng also arrives to help, but is severely injured.
Chen Changsheng, Niansheng (injured), and Yixiu escape the Night Moon Kingdom. Niansheng, knowing she can't accompany Chen Changsheng anymore, gives him a map. Chen Changsheng then enters the Xuanwu Kingdom, where he meets the Left Emperor who seeks immortality. He agrees to help the Emperor, but reveals his true motive: to bury his grandmaster, who has also reached the end of his lifespan.
Chen Changsheng brings his grandmaster's body back to his former sect. He then visits another old friend, Yixiu, who is on his deathbed. He expresses his sadness but has grown accustomed to the passing of loved ones. He later encounters Wanyan Yue, the Wolf King, who is tasked with guarding a bronze temple. He checks on her and leaves after a brief, tense interaction.
Chen Changsheng meets Aman, a young girl from the White Witches clan, and they bond. She admires his stability and unchanging nature. After helping to reconcile the Black and White Witches, Chen Changsheng prepares to leave the Ten Thousand Mountains. Aman insists on accompanying him, even if only for a small part of his long journey. She eventually ages and prepares for death, asking Chen Changsheng to give her a beautiful burial.
Aman passes away, inspiring Chen Changsheng to see his remaining old friends. He visits Yixiu, who is also nearing death, and offers him a proper burial. The world then enters a 'Golden Age' with new cultivation systems. Chen Changsheng meets Ye Hensheng, a disciple of Wanyan Yue, and learns about the Kunlun Holy Land's Heavenly Pride Gathering, where he hopes to find Nianci or learn of her whereabouts.
At the Heavenly Pride Gathering, Chen Changsheng meets Gongsun Huaiyu, a disciple from Wuli, who is now a commander of the Seventy-Two Wolf Smoke Sects. Wuli, whom Chen Changsheng mentored in the Ten Thousand Mountains, reveals his conflict with Jiang Bufan, the Holy Lord of Kunlun Holy Land. Chen Changsheng agrees to help Wuli, seeing him as a potential 'chosen one' to bear the Mandate of Heaven.
Chen Changsheng participates in a debate on the Mandate of Heaven, impressing everyone with his wisdom. He encounters Jiang Bufan, who attempts to recruit him and later attacks him. Chen Changsheng escapes and learns that his grandmaster Zuo Huang is still alive and has joined forces with Wuli. He and his allies prepare to fight for the Mandate of Heaven, supporting Wuli to become the 'Chosen One.'
Chen Changsheng obtains a wooden carving from Zuo Huang, recognizing it as one he gave Niansheng. He realizes that Niansheng is also pursuing immortality to stay with him. He then confronts Jiang Bufan, who is nearing his end, and learns about the greater secrets of the world and the upper realms. He buries Jiang Bufan and then prepares for another long slumber.
Chen Changsheng wakes up to find that Wuli and his allies, including Niansheng, have ascended to the upper realm, forcing him to follow suit. On the Heavenly Path, he encounters many fallen figures, including old friends, and finally meets a heavily injured Niansheng. They share a profound moment, affirming their complicated love and journey.
Niansheng sacrifices herself to protect Chen Changsheng in the battle for destiny on the Heavenly Path. He is joined by the Hundred-Defeat Immortal Venerable and others, fighting against formidable foes. As chaos erupts, Niansheng's final insights and a map she provided guide Chen Changsheng as he continues his endless journey, seeking answers and enduring the solitude of immortality.
