In Mixed Martial Arts, I Can't Be Satisfied with Being the Best in the World.

Reborn in the world of mixed martial arts, I got a sign-in system, with twelve monthly sign-ins and one annual sign-in every year, but there was a requirement that I had to comply with and not be exposed to outsiders, otherwise I would disappear. I quickly accumulated boundless power and extremely strong force. I originally wanted to stay for a while, but I didn't expect that the gold list would come from the sky. This time I can't hide it, the sign-in system will disappear, and the protagonist Xin Hao has now become the number one in the world. This novel and its characters are purely fictitious.
