I Have a One-Key Cheat: Becoming a True Keyboard Warrior

I, Xu Zigang, need only one key to subdue demons, vanquish fiends, suppress immortals, and stand proud above the world!

While asleep, Xu Zigang vaguely dreamed of a strange old man babbling nonsense at him.

When he woke up, he found himself in another world!

Did I transmigrate? I don't believe it!

He trains hard, all for the chance to meet that strange old man again.

Why?

So he can pick up his bonded spirit weapon and smash the old man in the face with it!
