The Greatest Demon King in History

How many of them came in thinking they were the strongest Bull Demon King in history? 😁

I feel like the protagonist is still not kind enough. Killing Japanese and calling himself a devil Killing the Japanese is inherently just, but the protagonist admits that he is a devil. Hey, what kind of character is this?

Selling dog meat on a sheep's head, what's wrong with it? It's enough to be the best.

It's said that Crimson's books all begin with the "most" in history, a blatant "book title" of water!

This one is more enjoyable, so why don't you write it again?

Does the devil show his conscience? No, it made me laugh so hard...

I just want to say one thing, don't write rebirth stories if you don't have enough experience. How do you think you're mature when you write a centuries-old weirdo into a stupid young man? Alas, it was embarrassing and painful to watch.

In the realm of martial arts such as the Republic of China, where firearms are powerful, and the martial arts training flow, what is important is not strength, but defense, speed, flexibility, being able to defend, being able to run, and being able to hide are the most important. If it is a ranged weapon, there is no hope of being able to defend it. If you are carrying a heavy load (high-strength armor is reliable for defense), if you can run, you can survive by avoiding the killing center.

Is this also called a devil? Do you feel a little bit evil in your daily routine outside of Japan? No personality at all

I feel like this protagonist is trying to sell someone else's meat.
