Male protagonist: This world is really terrible. I'd better choose to experiment.
The destined son who saves the world, the weird villain... All kinds of characters appear in the game.
Male Protagonist: Hey, this guy looks interesting. You want me to help you? OK, sounds interesting.
In short, this is the story of a scientist who works in laboratories in various worlds, raises children (?), And becomes a good brother/master/spiritual idol...
PS: 1. No CP, the protagonist focuses on experiments for 10000000000000 years.
2. The system is a good boy. However, it was very angry, angry, annoying, and disgusting with the protagonist at first (I won't tell you the reason). Later, after unknowingly gaining "father's love", it became a cute one again.
3. The author is a bad student, please forgive me if the scientist fails to write. The author is generally full of serious nonsense.
4. The author's writing is terrible. I hope readers can appreciate it and give me a chance to improve o(*////▽////*)q
