Invincibility Starts with Selling the System!

Jiang Fan accidentally obtained a system, and the function of his system was to sell various systems. "Want a system? Yes, you can get something in exchange." Empress: "I want to resurrect my brother." Jiang Fan: "Okay, then you can replace it." Emperor Ye: "Sir, can you resurrect my parents?" Jiang Fan: "Of course, I'll give you your chance in exchange." Everyone: "I also want to buy the system." Jiang Fan looked up to the sky and sighed: "I'm really just a porter of the system." This novel and its characters are purely fictitious.
