National Reiki Era

An extraterrestrial divine corpse fell to the earth, and its aura began to revive. Because of a divine corpse relic, he watched helplessly as his teammates died one by one in front of him. Because of a ring he picked up on the roadside, he was reborn against the odds. He returned to three years ago and decided to use his three years of memory to become a strong man and take his destiny into his own hands! However, he discovered that there was a huge world inside the ring, and there was an empty city in the world. How should he develop in the face of such a huge empty city? What to do? Waiting online, it's very urgent!
