In the snowy region of the far north, snow falls all year round.
Zui is a demon who cultivated by absorbing resentful spirits. Eighty years ago, he came to the throne on his own to protect the peace of the country. However, due to years of grudges, he was often on the verge of losing control.
Once when she was hunting for grudges, she originally wanted to find some grudge spirits to sustain her practice, but she found a troublemaker in the ruins - a little cat tribe monster with mixed blood.
Xueyu was once slaughtered by a cat demon, and the clan members were filled with criticism. Zi could only send Si away repeatedly, and watch her crawl back to him again and again with her obsession.
In the end, Zai Si's demon age was comparable to that of a human being when he was five years old. After all, Zui couldn't overcome the softness in his heart and kept this little troublemaker by his side.
Teach her defensive spells, guide her in close combat, and watch her grow from a timid little hairball into a powerful young assassin.
But no one knew that this cold and powerful snow lord had already been entangled in the trouble he had picked up and became a disaster that he could not get rid of.
When the resentful spirits in the snowy area dried up, Zuo had to take Si on a cross-plate adventure. The dusty past and unknown crises followed one after another.
