genius? In Tang Yi’s eyes, it was just a joke, not as good as a pet dog in the system.

- Description from Uukanshu

Have you ever considered, what is a Limit? Well, I have. I’ve seen people who were as strong, as wild animals. Those that were faster than the wind. Some that shined with intellect. Yet, what are the Limits of mankind’s strength, or intelligence?

No one seems to know. We develop more and more, seemingly without an end. What if, someone was the smartest in the world? Would that suggest the Limit? What if, someone was the strongest in the world? Would that be the Limit? Would that make that someone, more than a Human? These are just questions, but what if I saw people reach their Limits? What if I know what happens, when you break the Limits? What if I were to tell you about it, would you believe me?
