She Holds the Lamp to Illuminate Reincarnation

In ancient times, the twin gods fell, the Human Sovereign manifested, and the nine great paths established the world. Yu Qinghuan, a princess bearing the atavistic Chaos bloodline, was abducted into the Chaos Temple as a vessel for the shards of Chaos. After killing her closest friend and crawling out of a mountain of corpses, she embarked on a path to godhood fraught with cost—every use of Chaos power erodes her soul and body. In her flight, she finds refuge under her master Mu Chunge, and at Tianyun Sect meets the lively, elf-like Bai Ling'er, whose clear bell-like laughter shines like a light into her shadowed world. Thereafter, she breaks the temple, ventures into secret realms, enters the northern frontier, and battles the imperial court, her blade of the mundane world cutting down all demons and monsters, with more companions and loved ones gathering behind her. Yet behind all the glory lies a truth she has yet to see: this is the 1,750th reincarnation. The God of Deception weaves his chess game in every cycle, toying with mortals. Until the arrival of 'Qi' reveals the full truth—at the end of the cycle, she must become 'Qi', bearing all of past and future, shattering the false world to open true freedom for all beings. And at the end of the cycle, she will once again take Bai Ling'er's hand and walk toward her new world. — Description from novelcodex.org
