Legend has it that there lived a poisonous young master in Huayun Mountain. He had a peerless appearance, but his heart was as poisonous as a scorpion. In fact, he was just a child who was abandoned in a poisonous cave. He unexpectedly fell in love with the poisonous goblin in the cave, and was taught to grow up by the boss of the poisonous cave, an old snake spirit with thousands of years of experience. Occasionally wandering out of the cave, and often being knocked down when meeting people. At this time, the elders in the poisonous cave will go out together, causing the person to die miserably. Hence the legend that "there is a demon boy in Huayun Mountain who captivates the country. When he meets people, he steals their hearts and eats their flesh."
After going back and forth, the poisonous child not only did not fear and dislike people because of being knocked down, but also became very greedy for people's body heat. Thinking that I am also a human being, I decided to go down the mountain and travel around the world. Although they were reluctant to part with it, the poisons in the poison cave agreed with Du Zi's decision, so the snake spirit boss took his son Xiaobao and followed Du Zi down the mountain.
Although the poisonous child has been taught a lot of common sense in the human world since childhood and has read many books on the human world, there is always something missing. In the process of traveling to various places, they meet many people and things, and the poisonous children will grow up as a result. However, as the journey begins and ends, the group of people, who were originally spectators, also have their own love and hatred, and some things may be beyond the memory of this life...
