A world of high martial arts that combines cultivation, magic and doomsday crisis (refer to "Edge of Doom" and "Star Wars Civilization"). The continent where the protagonist is located is on the verge of collapse due to the invasion of "extraterrestrial demons". The ten empresses are reincarnated and shoulder the mission of saving the world. Every time the protagonist gets to know a reincarnation of the empress, he can share his luck and unlock the corresponding abilities (such as the Heaven-Swallowing Demon Technique, the Immortal Heaven Technique), but he needs to complete system tasks to change the empress's "destiny". The system is presented in the form of a "book". Each choice of the protagonist will rewrite the original plot, triggering the butterfly effect. If you forcefully follow the original plot, the system will lower the "social death" penalty (such as dancing in public), pushing the protagonist to take the initiative to break the situation.
