Cultivation to Immortality, but Campus Cultivation System

Xu Chen traveled through the world of cultivating immortals and suddenly awakened to the system. He thought he could turn around, but he found out that it was a campus training system. Only by training people into singers, actors, and female CEOs can they get rewards. Where can I find these for you in the world of cultivating immortals? Xu Chen can only rely on the knowledge from his previous life to teach students, turning tone-deaf people into normal people, turning the second grade disease into a middle grade two, and turning facial paralysis into rich emotions... A few years later, Xu Chen looked at the swordsman, number one assassin, and martial arts leader in front of him and fell into deep thought. Do you call this a singer, actress, or female CEO?
