Can write: God Killing, Ming Ke, Divine Seal, Douluo, Curse Return, Fox Demon...
I will add what comes to my mind later. You can also contribute. The pace will be a little faster.
Key points: The male protagonist is the system, the female protagonist is strong, and she also has a cheat. Both the female protagonist and the male protagonist can be read.
Maybe write a side story
If the writing is not good, please be careful. The author has a glass heart.
Intention: life and death, never leave and never give up
