This Blind Man Is so Tough That Even Gods Can't Break His Defense.

My name is Zhang Wei. I traveled through time and became a blind man. My profession is a knife-catcher who licks blood from his knife's edge. I was panicked until my system expert patted me down and gave me a copy of "The Indestructible Power of the King". As a result, my martial arts career became simple and unpretentious. The leader of the Demon Cult struck with all his strength, but I didn't move at all. I asked with concern: "Does your hand hurt?" The leader of the martial arts alliance struck with his sword and the sword broke. I suggested: "Next time, change to a better weapon. I know a blacksmith who will give me a 20% discount on my name." Now, everyone in the world wants to kill me, but they can't do anything about it. Looking at the ultimate task of [becoming number one in the world] in the system, I sighed. "It's not that I don't want to, it's mainly because I'm a blind person, and being the boss... Is degrading!"
