Whether it is fighting skills or cultivation talent, he is the number one person in the world.

The physical liberation of tens of thousands of muscles compressed, the bones more than a thousand times harder than the hardest steel, the ghostly back of evil deeds, the recovery rate of flesh and blood rebirth, etc.

One person surrounded the entire Qibuhai, one person surrounded the top, one person invaded the city of advancement, and one person invaded the Holy Land and sat on the Void Throne.
