Conquering the World with Ancient Martial Arts [Ancient to Future]

[Off-the-charts combat ability. Hated by everyone. Ancient-world bottom VS cold and domineering. A strong moral compass. Future-world top] Dong Nuan, a great demon from ancient Earth, transmigrates. The new world is just as unkind to him. Sigh. Nothing for it. He has to grit his teeth and press on. Qiao Liang, the strongest person in the interstellar realm, is perfect in every way except for his poor eyesight. Not only does he fall for the great demon Dong Nuan, he even keeps him by his side. See? He's practically asking for trouble. This is a ridiculous story where everyone wants me dead, but I don't want to die, so I have to make you all die instead. Then I have so many enemies that I accidentally end up ruling the entire galaxy. [Shocking! After traveling through time and crossing galaxies, he ends up ruling the entire universe this way!!!] [An ancient martial artist transmigrates to the future and rules the galaxy. His golden finger is insanely satisfying!] [The blurb may be revised later, but the major setting will stay the same.]
