Three Seven Tribulations: Paradox Weaver

Yun Erge, a 37-year-old librarian, received half a bronze mirror on her birthday night. The blood shadow in the mirror, Qi Jue, and the "37 cycles" warning drew her into a fast-travel paradox. She reunited with Qi Jie in 77 worlds, including the Republic of China, the End of the World, and the Interstellar, but fell into the fate of "loving him is destruction": he was the comrade in the End of the World who sent her the vaccine, and the interstellar judge who personally sentenced her to death... When the truth of the 37 paradoxes is revealed, she discovers that the only key to breaking the cycle is to kill the man who has died for her in every life.
