I'm already Invincible, Why do I need to Practice?

[Invincible + A cool story that makes you doubt your life + A silver-haired male protagonist + An invincible background]

The earth in his previous life was too chaotic. Su Chen had no interest in fighting and killing in this life. He just wanted to drink some wine and see the scenery of the world, that's all. But there was no way. If he didn't cause trouble to others, others would cause trouble to him. Helplessly, he had to kill an immortal emperor in an instant without noticing. Since then, no one dared to cause trouble to him.

Everyone asked, "Why are you so strong even though you never practice?"

Su Chen said calmly: "I am invincible, why do I need to practice?"
