Legend of Qinglong Mountain

It tells the story of Amu, who went from a happy family to being dependent on his mother. He accidentally obtained a spiritual pearl, but it caused trouble. In order to protect his homeland, he went into the mountains alone to look for the dragon. He narrowly escaped death, swallowed the spiritual pearl, survived a thunderstorm, and transformed into a dragon. He originally wanted to keep the peace of the village. But because of his terrifying true form, he was regarded as a ferocious beast by his fellow villagers and was chained to the top of Qinglong Mountain.
