Become a Master after Becoming Invincible

Visually invincible text. Because it was relatively white, I couldn't read it... But I could tell what kind of story it was about. The protagonist was an invincible old monster who felt empty, lonely and cold because of his invincibility and immortality. Only by teaching his apprentices and watching their progress could he feel a sense of accomplishment. There was only one monkey at the beginning, and the apprentices had to rely on him to accept them. I haven't read the latter part yet. Maybe I'll look through it in the future if I'm really short of books, and I'll write a more insightful introduction later~

Start being invincible and raise disciples

A new book, it feels like the main character is playing a fitness game. It's pretty good. I'm going to read it.
