In the twelve realms of the fairy world, the twelve divine kingdoms of Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Sheep, Monkey, Rooster, Dog, and Pig are established in separate kingdoms. For thousands of years, a "zodiac competition" has been used to determine the ranking of superiors and inferiors. The winner controls the destiny of the fairy world, and the loser is suppressed by heaven.
Lingxi, the young master of the Rat Kingdom, has the bloodline of an ancient chaotic rat. However, he was killed by an adulterer when he was young, and his spiritual veins were damaged and he became a "waste". He was despised by the whole clan and ridiculed by other countries; Tuoshan, the young master of the Ox Kingdom, was born with supernatural powers but was simple and pure. Lingxi is willing to claim half of his cultivation level; Liefeng, the young master of the Tiger Kingdom, is unruly and domineering but has a special regard for Lingxi; Ao Chen, the young master of the Dragon Kingdom, is cold and aloof, shouldering the heavy responsibility of reviving the dragon clan, but has a destined bond with Lingxi...
When the good-for-nothing Mouse Master unexpectedly awakens the bloodline of Chaos and holds the ancient inheritance, the balance of the Twelve Divine Kingdoms is completely broken. With treacherous palace battles, life-and-death competitions, and cross-border alliances with hidden murderous intentions, a ranking battle concerning the fate of the twelve nations is about to begin.
Lingxi joins hands with Ao Chen to break the situation with the agility of a mouse, and escorts with the majesty of a dragon. He protects his family and country in the face of counterattacks, and sticks to his true love in life and death. From being the last loser to being the lord of all realms, from testing each other to rushing in both directions, they will lead the twelve kingdoms of the gods to break through the shackles of heaven, write a zodiac legend that spans ten thousand years, and reveal the ultimate secret of the ranking of the twelve zodiac signs!
