I Have a Memory Palace

Lu Yuan traveled through time and entered a precarious world. 18 Years ago, the three most powerful countries in the world jointly opened the door to subspace. The old days cast a silent gaze on human civilization, and weirdness and evil crossed planes and rushed towards the earth. But luckily, God was kind to him. "The Memory Palace has eight floors in total, and your memories and powers are stored inside." "But I don't remember ever having amnesia." "Because you're dead." As long as the eight-level seal is unlocked, you can become the second god of the subspace. But when the sun was replaced by the eyes of the outer gods, the ubiquitous black clouds covered the sky. On one side are the strange things coming like a tidal wave, and on the other side are the extraordinary beings who are fighting endlessly. How should human civilization deal with itself? [I am Lu Yuan. When you read this letter, I will be dead.
