Please recommend a cute old cartoon about dragons. The main characters are the sons of the Dragon King. It was produced 90 years later, and the villain is a mouse demon.

[Note: It seems that the protagonist was framed by the rat spirit and broke something. Later, he traveled around the world and often met his brother and the rat spirit.]
Added:
He remembered watching it on CCTV. It was a 2D cartoon from seventeen or eighteen years ago. He had almost forgotten the plot. He only remembered the following two clips:
The protagonist met a super big turtle (actually, it was a big turtle). He didn't know it, so he called it a big turtle. After talking to it for a while, he rode away on a cloud. Before he left, he still shouted,"Big Turtle".
Chapter 02: An immortal being worshipped in a Taoist temple (probably also a dragon, but I don't know if he's the protagonist's uncle or brother) was expelled because he couldn't satisfy the greedy wishes of a few bullies. Coincidentally, the rat spirit came over and turned into some kind of great immortal. He turned other people's money into money and gave it to the two bullies to be worshipped, so he robbed the Taoist temple. The protagonist came over to reveal the true face of the rat demon with the immortal. The final plot of this episode should be that after the rat demon was driven away, the immortal returned to the Taoist temple.
[Additional comment: If anyone knows the name of this cartoon, please tell me. If you think the points are too little, you can add more. I'm just afraid that if you don't have an answer in the end, it will be a waste, so I didn't put too many points in.]
[Note: The first son of the legend of the "dragon gives birth to nine sons". It is shaped like a tortoise. The tortoise that we often see in ancient buildings carrying steles is the one.] I remember that in the cartoon, the protagonist rode a cloud somewhere and saw a very large turtle (about four or five stories high) walking on a human's feet. He went up to talk to it and learned that it was Huanhuan, his cousin or brother, who was ranked in the highest position. In the end, he rode the cloud and left.

Answer 1

I recommend the novel Douluo Continent III Legend of the Dragon King. The main character of the novel, Tang Wulin, is also the son of the Dragon King. He possesses powerful soul beast abilities and dragon race genes. At the same time, he is also a legendary figure on the Soul Master Continent. There were also villains in the novel, but they were not rat spirits. I hope you like this fairy's recommendation. Muah ~😗
