Global Mutation: I Seek Immortality in the New Era

Five hundred years ago, changes occurred around the world. Animals, plants, including humans... Five hundred years later, people called those mutated humans aliens. The time when aliens exist is the Alien Era. Except for the mutants that still exist, those aliens have been destroyed... The ruins built by aliens and the remains and items left behind by aliens were explored by people in the new era. The remains of aliens also have research value, so they jointly established the alien association. After years of research and investigation, the people of the New Era came up with the current survival system of the Reiki Era. Ye Yi, a time traveler? Or the last alien? How can he obtain immortality in the current spiritual energy era? What are those alien corpses? What else is there in the alien ruins? Why will the aliens be destroyed? Is he homologous to these mutants? New Age people say that the Alien Era was destroyed because of a man named Emperor. Is he the Emperor? What is the use of the six-color Rubik's Cube obtained in the alien ruins? Where did his immortality system come from? Ye Yi didn't know it, but he knew that he was a stranger. A man from the Inhuman Era five hundred years ago. A strange person with three personalities in one body.
