Doomsday Infinite Restart

An unknown celestial body is crashing into the earth. Evil and strange doors are exuding terrifying gas. All kinds of mutated monsters are running rampant. Is it a world-destroying attack from a high-dimensional civilization or a means of self-preservation for the earth's resistance? In the face of survival and destruction, twisted human nature and dark hearts, only killing and strength are the only guarantees for my survival. This is a playground for the strong and a hell for the weak. There is no order and no morality. The law of the jungle is the only principle. Do you dare to come?
