The monster is a true dragon, not a regular dragon. The ancestral dragon egg has already hatched, so the monster is not a dragon at all. It is a tiny thing that is making the noises, and the monster will catch it and kill it. They will split up and meet at Linglong lake. The power of the punch is equivalent to 4,000 dragon scales and barely killed the monster. They decide to cut off their exploration of the Heavenly dawn secret realm.
