The World Is Stunned! You Call Your Brother Ordinary?

Ye Nan gets a System and, in just a few short years, becomes a global financial titan, the world's top assassin, a Nobel Prize-winning physicist, a pioneer in artificial intelligence, a national treasure of an actor, and an art master... Yet just as he reaches the pinnacle, weary of scheming and backstabbing, he conceals his identity and returns to an ordinary life with his older sister!

Sister: My little brother is so ordinary, and so lazy. What will become of him? I’m afraid he won’t even be able to find a wife!

The whole world is stunned: What? You call your little brother ordinary?
