After becoming a god, due to the intersection of time and space, the protagonist accidentally travels through the prehistoric world and learns that he is the demon ancestor Rahu. 3000 Demon gods and many powerful prehistoric figures are also resurrected by chance. This is a "conquering the prehistoric system" that comes to mind. The protagonist cuts thorns with a shawl along the way, fights fiercely in Beihai, defeats Hongjun, subdues the demon gods, and prepares to unify the prehistoric world.
(There are many female protagonists in this book➕The system does not come out often➕Not the Virgin)
Sometimes there is nothing you can do about it if it is not consistent with history. Please don't complain.
