Fortune-telling animation ending _ Fortune-telling animation

I figured it out. In the cartoon "Song of Teenagers", Fei Xuan tells the bleak fate and calculates two results: good luck: the world is ruled together, and the dragons are leaderless. At that time, they can turn dragons into dragons and fly to the sky; Great evil: the dragon fights in the wild, and the blood is yellow. The Boy's Song is an antique online cartoon produced by China Film every year and co-produced with Bi Li. Adapted from Zhou Munan's original light novel of the same name. The work tells the story of four young chivalrous men with bizarre life experiences and heroism.
