Please recommend a novel of the infinite genre!

I'm looking for an infinite system novel! It was a novel that had become popular a few years ago.
The main character had transmigrated to a parallel world, and he had transmigrated to this world's body. There was also a system that could exchange abilities, learn abilities, and even go to different worlds to cultivate.
The worlds that the protagonist had been to included Diablo, Legend of the Sword and Fairy IV, Three Kingdoms (Chaotic Version), The Legend of Qin Shi Ming Yue, The Legend of the Condor Heroes, the world of the Goddess of Wagtail, etc.
The abilities in the real world were divided into (from low to high):(the lowest level was ordinary people), yellow, mystic, earth, heaven, and god (the god level was divided into many levels).
The main character had a huge harem. In the real world, there was a dancing god. The Legend of the Sword and Fairy had recruited Han Lingsha and Su Yu (the main character in this world was Ziying).
The protagonist entered the Night of Destiny to replace the protagonist, and the protagonist entered Qin Shimingyue to replace Gao Jianli…

Answer 1

I recommend you a novel called "I'm the Only Player in the Apocalypse of All Worlds". It's a novel about the infinite universe. It mainly tells the story of the world changing and the world of another dimension descending to the human world. The protagonist is the only player to fight monsters to level up. He uses genetic fragments to fuse with supernatural monsters, and there's also the story of the archive system defeating all kinds of monsters. This is a novel about the dark side. If you like such works, you can read this book. I hope you like this recommendation. Muah ~😗
