Qin's Moon: Ancestor, You Asked for Immortality

Su Miaoling, a modern-day fan of the Qin's Moon franchise, receives a strange jade pendant and finds herself transported into the world of The Legend of Nine Songs. There, she encounters Han Fei, Zhang Liang, Hong Lian, Wei Zhuang, and other key figures of the era. By chance, she meets Ying Zheng—and is so overwhelmed by his commanding presence that she finds herself drawn to follow him, only to discover that she is in fact his descendant, bound by blood. She soon realizes that a group of pioneers has already gathered around Ying Zheng. Together with them, Su Miaoling helps reform the Qin state, propelling it to become the foremost power among the Seven Kingdoms. She orchestrates the defection of key figures from Han, dissolves her own Su family, and sends them to "subvert" the other six states. Before long, the six kings voluntarily pledge allegiance to Qin, each vying to be the first to embrace the new reforms. Ying Zheng unifies the realm without ever drawing his sword, leaving him to wonder if some divine cheat code has been activated—how else could the six states have delivered themselves to his doorstep? When the pioneers notice the first strands of white at Ying Zheng's temples, panic sets in. They desperately scour the land for the legendary elixir of immortality—a potion that supposedly does not exist. Meanwhile, Su Miaoling and the guardian spirit Xi, who resides within her, originally came to this world searching for clues to her missing parents. But their quest unexpectedly transforms Ying Zheng into the Xuan Huang—a title never heard in the mortal realm, signifying not only an emperor but also the guardian of all humanity.
