Fantasy: You Can Become Stronger by Fooling People

After Zhou Xiao traveled through time, he was bound to the sales system. I was asked by the system to sell some strange things. "My box contains the best elixir! You can't open it now because you are not good enough, otherwise it will dissipate immediately! Now it's only 999!" "I've killed dragons and monsters with this stick, and I only need 998 today!" "This painting of mine was made by an expert. Only those who are destined to see the content in the painting can only pay 888 today!" From then on, Zhou Xiao never returned on the road of deceiving people. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
