The Great Fission has come, and the earth has become a doomsday wasteland. Invaders from other worlds have distorted the laws of physics. Human civilization is on the verge of extinction. Traditional technology and magic are useless. Physics tycoon Chen Zhou activated the [Quantum Observer System] out of desperation and gained ultimate physical analysis and simulation capabilities. Starting from transforming a useless knife, he upgraded an abandoned nuclear reactor into a high-efficiency fusion core, reconstructing energy and matter with subversive "truth physics". When the alien army came again, Chen Zhou no longer relied on guns and magic. Instead, he used the "Quantum Cutting Blade" to tear apart the enemy's defense and the "Space Shock Annihilation Field" to decompose the alien lord. He restored "magic" to controllable physical laws, shocking survivors around the world and becoming the only hope for human civilization. But the more powerful alien lords have been alerted, and the deep secrets of the universe are slowly being revealed. Can Chen Zhou lead mankind out of despair, reshape the world with truth, and become a doomsday restarter?
