I Am Not the Master of the Supernatural World

When Chu Xiaoyao woke up, he traveled through time and space and came to an ancient world. There was no golden finger, no system, only a dream. The people in the dream... Were all his mentors? Chu Xiaoyao's eyes widened with disbelief on his face. Based on the years when he and his parents were fighting wits and courage, skipping school, not doing homework, eating everyday, teachers, in my eyes, they didn't exist, just... "I just graduated from nine years of compulsory education, three years of high school, four years of college... How can I continue to go to school again? It's more or less unacceptable!" Why do I still have superpowers? How? Am I still the master of supernatural powers?
