Do you remember shulang beating up baotian? They left him there after beating him up. It was supposed to be dark alley in the novel. Zhang chi was looking for prostitutes. That place was supposed to be where prostitutes are picked up. So zhang chi saw baotian. Baotian told him to take him out of there. So zhang chi thought he's selling himself. Zhang chi even bargain saying he would only pay 100 yuanππ. But baotian was half unconscious didn't understand what zhang chi was saying. So he agreed. the rest is history. I do feel bad for baotian
