Zhang Fan thought that he was just a little guy who could only sell milk tea, rehmannia pills, and divine oil to make money and move. However, he did not expect that the immortal cultivators he met thought he was a peerless master and gave Zhang Fan money, treasures, and women, just to get Zhang Fan to look at him. But... I'm really just a little bitch, why don't you believe it?
