The tribe is in danger. In order to survive, Lingxi, the last priestess, uses forbidden techniques to summon the patron saint. However, she accidentally summons a "little black dragon" with amnesia, severe injuries, and a bad temper. Lingxi had no choice but to feed and comfort him, "raising" him as a cute pet, and at the same time using his power to open up territory for the tribe and intimidate all directions. Unexpectedly, this "little black dragon" turned out to be the ancient dragon god Yuan Shen. After he regained his memory, he not only never left her, but turned into a madman who protects his wife. He held the world's most precious treasure in front of her, helping her to counterattack step by step from the last priest to the only god queen that all races looked up to. The whole story focuses on the growth of the heroine and the revitalization of the tribe as the overt thread, and the recovery of the dragon god's memory and the uncovering of the ancient conspiracy as the dark thread. The plot is dense with exciting points, and the emotional line is single-minded and sweet.
