The Legend of Alien Martial Arts Heroes

The story begins with an inexplicable martial arts novel written by Li Kai. He is a father who picks up his children all day long, and is suddenly sent to a mental hospital as a madman. Later, he escaped and encountered a mysterious alien rebellion. He met the leader of the aliens. At the leader's suggestion, they decided to take refuge in a broken novel written by Li Kai, waiting for the alien leader to contact his men to eradicate the rebellion. The alien has no body, and the leader transforms into a peerless beauty, and adventures with Li Kai in the book he wrote. As the adventure progresses, it turns out that there are other aliens who have already entered it, and they play the world in the book as an adventure game... Li Kai gained friendships along the way, and also gained the love of many women. While he was worried that he could not be sorry for his wife in the real world, he also persuaded himself that all this was just fiction, so he could just enjoy it... What did he choose, and can he successfully come out of the world in his book? Why do these aliens treat the world he wrote about as a paradise and play various roles in it?
