A long time ago, humans, monsters, and demons all lived on the same land. The human race cultivates spiritual power, the demon race cultivates demon power, and the demon race cultivates soul power.
Although there are occasional disputes, it is thriving.
Until the leader of the demon clan accused the human race of stealing the demon clan's most precious treasure - the demon heart, the demon clan fished in troubled waters and wanted to annex the southern territory of the human clan, and the three major races started a war.
The war raged, and the people and ordinary little monsters fled in all directions. Corpses were scattered all over the field, and rivers of blood flowed.
The human leader Zhao Tianqin and the demon clan leader Hu Erbai raised their swords, swept across the demon clan, and drove them into the westernmost Sunset City, ending the war.
The leaders of the two tribes signed a friendship contract at the same time to divide the area. People from each tribe moved within the area and were not allowed to cross the border without approval. From then on, all ethnic groups recuperated, the economy of each city was in dire straits, and everyone lived in peace again.
Linyu, a little cat, is a two-hundred-year-old little demon whose unreliable adoptive father has not been heard from for three years, so he goes to the human world to find his father.
When he first arrived in Haicheng, the penniless Lin Yu's stomach growled with hunger. The yamen announced that anyone who provided clues would be rewarded. Forced to make a living, he had no choice but to try his best. He met a Taoist priest who caught monsters on a narrow road. To protect his identity from being discovered, Lin Yu ran away without him.
Unfortunately, God failed to fulfill his wish. The identity of the little demon could not be hidden, and there was no hope of freedom for the demon. He had no choice but to wait by his enemy's side, waiting for an opportunity to escape.
However, the world is not as beautiful as the storytellers say. It is full of dangers and strange things. The little demon and the little Taoist priest who turn danger into good fortune discover a bigger conspiracy behind ordinary cases.
The one person and one demon who were forced to get involved, either actively or passively, shouldered the important task of tearing apart the dark clouds and restoring peace to the world.
Purpose: live a good life
