In order to get rid of this strange curse, he traveled across thousands of mountains and rivers, visited famous doctors and explored secret places, just to find a way to solve the cause of the disease. Unexpectedly, an accident threw him into a different world. In a different world, strong immortal cultivators and monsters run rampant. I never thought that his weird symptoms would turn into some kind of physique that can lead to crazy immortal cultivation. Let's see how he climbs to the top step by step and aspires to the top.
