Ten years after Qin's death, the world was in turmoil again. When the stars changed and the Seven Constellations reappeared, an organization older than the Yin Yang Family surfaced. They call themselves the "Heirs of the Star Soul", hold the lost "Ganshi Star Scripture", and actually want to change their fate against the will of heaven - resurrect the eternal emperor who has been sleeping underground.
Tianming and Shaoyu follow the star map left by Yue'er and embark on a journey to find Kunlun Ruins. On the way, they discovered that every time they passed a place marked by the stars, a village disappeared mysteriously. At the same time, while exploring the Xianyang underground palace, Gai Nie and Wei Zhuang encountered the "Luo Sheng" killer who was supposed to die, but Ying Zheng's coffin was empty.
Zhang Liang pieced together the shocking truth from the Confucian secret pavilion: Canglong Qisu is not a seal, but a key. Two thousand years ago, the Zhou royal family dispersed the power of the Nine Cauldrons to seven places. Now the descendants of Star Soul must gather this power, not only to resurrect Ying Zheng, but also to restart the ancient forbidden technique of "Jedi Tiantong".
When the stars returned to their positions, the Yin-Yang curse seal in Tianming's body suddenly went berserk. It turns out that he is not only the guardian of the key, but also the last seal. Facing his former partners turned enemies, he must make a choice: should he escape fate again, or end this thousand-year reincarnation in the name of a Mohist giant?
