I'll describe parts of the story I remember. MC was part of a troupe and became a disciple of the poison and medicine masters of a cult. Because he's got a special body constitution he was able to withstand their experiment on him. Then in the jianghu he went to a place took control of it and got revenge on the people who did bad things to their troupe. He became stronger, killed more enemies, expanded his territory and then killed young masters with white hair and ice powers of the cult. And his masters took his side.
