What I distinctly removed is that there an ancient China arc where the ML just transmigrated over from an apocalyptic world but the MC failed the mission in that arc. To fix things, MC then had to transmigrate to the apocalypse world ml just came and the stuck himself to the Ml. Ml eventually remembered their life in the ancient times and the mission was finally passed. Please help
