Zhou Zheng traveled to a world of cultivating immortals, and he awakened to an exchange system. As long as he sold the various skills, swordsmanship, Taoism, etc. Given to him by the system, he could get various rewards from the system.
He doesn't like all kinds of fighting and killing, he just wants to get a wife and then live forever.
But what he didn't expect was that the skills he sold were actually practiced by others, but he himself couldn't practice them at all.
"System, why can others practice the exercises you gave me, but I can't?"
System: "The host qualifications are too poor."
Zhou Zheng: "I***."
