This is a casual book, with a very casual plot. The first thousand chapters have been grinding monsters and upgrading, cultivating the world view of immortality, and the world a thousand years later, expanding to other worlds, modern times, superpowers, and interstellar fleets. Don't worry about whether it makes sense or not. Pursue the lost treasures in the universe, cultivate immortality, and have nothing to do. Launch a Gundam, fight space pirates, and open a harem. Is there anything wrong with this part? I'll finish it before I start writing this part. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
