The Legend of Kunpeng Reborn

"There is a fish in the North Ming Dynasty, and its name is Kun. Kun is so big that I don't know how many miles it is. It turns into a bird, and its name is Peng. I don't know how many thousands of miles it has on its back. It flies in anger, and its wings are like clouds hanging down from the sky." No way, I am Kunpeng, the demon master who is said to be shameless, but he is a saint after all. Who am I? Ten thousand years of cannon fodder?
