"Why did he come out to cultivate alone with such a hidden danger?"
Chu Nan felt a little regretful.
However, this was not the time to think about these problems. The young man's situation was clearly very bad. If he did not quickly help, he would be dead.
Chu Nan sat down beside the young man and carefully looked at the abnormal situation on his face, neck, and other exposed skin. He discovered that the black color indeed seeped out and did not stop on the surface, proving that his problem was inside his body.
As for whether it was related to the cultivation method, he was not 100% sure now.
Chu Nan thought for a moment and felt that it was impossible to make an accurate judgment just by looking at a portion of his body. He raised his hand and took off the young man's shirt, planning to take a good look.
As soon as his shoulder was revealed, Chu Nan immediately frowned.
