After Lin Shen was reborn, there was a system in his mind - "Doomsday Simulator". This system can "simulate" various catastrophic scenarios that may occur after the end of the world in his consciousness. It is not a simple infusion of information, but allows him to experience disasters that have not yet happened from the perspective of a "bystander". Each simulation consumes his mental energy, and he will briefly lose consciousness after the simulation is over.
