Came to Steal, Now I Lead!

Su He sells fake medicine on the street and lets his sister, who can fight, clean up the trouble he starts. He is loud about money because he wants to buy her a house. He goes up Shushan to steal something and finds Qingxu, an elder of the sect, cornered and dying. Qingxu passes him a lifetime of cultivation and hands him the sect leader's token, then dies. Su He does not realise what he has been given. Shen Qishuang and the other disciples see the token, bring him back up the mountain and treat him as the next sect leader. He is fitted with robes, shown the treasuries and the halls, and starts working out how much of it he can sell. He brings his sister up to the mountain as well. The power he is carrying has a danger in it that he does not know about.
