Jiukong

This book is not a fast-paced reading, but a high-intelligence reading. It is boring and can easily lead to self-doubt. Most people insist on not reading it. If it is really boring, it can be used to kill time or be used in a daze. It will be updated every month or a year when I think of it. I may change it if I think of better content. In this way, we slowly travel together in the universe, with no direction and no end, and after nine turns, we return to zero.
