The Weakest Demon in History

This is the first novel I tried to write, I hope you all like it. The main plot is mainly the story of the protagonist being selected by the demon god who traveled through space, becoming the guardian of god, and finally helping the demon god return to the demon world and take control of the demon world. I plan to write this novel in the third person and try to use recent popular memes to make everyone laugh. I know that there are many novels of this type and the competition is huge, so it is just a small attempt. If you support me, I will continue writing. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
