This Guy Is so Naughty

My name is Ke Jiu, Bad news, I traveled through time. Good news, I have a system. But, why did someone block my crossing point? He said that in five hundred years he would snatch his wife and destroy his whole family. He also said that he was a devil. 666, There are still demons in this world. Can you travel through time again? Whoever walks forward in light and darkness will find himself in the abyss if he takes one wrong step. The only thing you can do is to be careful and cautious. Even if you say I am sinister and ruthless, I don't care. Demons and patterns are intertwined, where are the angels? I am the god, leading mankind towards destruction.
