I Lead the Villains to Support Justice in the World of Immortality

Xingli, a jobber, went through the book and time-traveled into the Demon Lord's scumbag master. At the beginning, she was dragged away to be fed to the monsters. It's okay, the system waved its hand and took Xingli back to the Demon Lord's youth. Xingli thought that the Demon Lord was just a pitiful person at this time, but... System: [Detected that the villain destroyed a sect ten minutes ago! [Progress in preventing villains from killing people and destroying the world: -100%] Xingli: .... She doesn't want to do it anymore! System: [Your current mission is to prevent the second male from killing someone. Xingli: ... The second male lead has picked up a big knife, what should I do? System: [Don't be afraid, hurry up! Grab his sword and appease him! Xingli: Got it! Grab his knife and kill for him! System: [The second male lead is about to fight! ! Xingli: Got it! Is the second male lead in danger? Toolman Xingli blocks the knife~ Mo Sheng looked at the former master who did not know how to live or die, and slightly curled his lips. He thought she was an undercover agent of the Immortal Cultivator Sect, in order to kill himself, the devil with a notorious crime. But who knows, when he fights, she blocks the knife; when he kills, she grabs the knife.
