Shen Hanzhou, the protégé of Beidi, hides the wild fire of revenge with his eyes like ice fields, and the heart-eating Gu on his wrist is his sharpest blade; Xie Linyan, a hidden noble in Shengjing, uses his white brocade robe to cover his cloud-shaking hands, and the heart-eating Gu locks his unspoken hatred.
Both of them are beauties who astound the world, and they are both hunters who lurk in the dark. The first time they met in the Hall of Taihe, when their eyes met, they knew they were the same kind - the same paranoia, the same cruelty, the same longing for the only light in the mire.
The Gu insects in Southern Xinjiang have formed an alliance, with the same heart Gu entangled in each other's lifeblood, and the Heart-Eating Gu is ready to devour each other's enemies. They are the most dangerous variables in the court's chess game. They work together to overthrow the powerful, wash away old grudges, and use ruthless means to clear the thorny road ahead.
No one knows that these two "venomous snakes" who stir up trouble will lick each other's wounds late at night and give each other all the remaining tenderness. They are each other's armor and weakness; they are accomplices who go to hell together, and they are the light of mutual redemption in the darkness.
When the Gu insects resonate and their hearts beat at the same frequency, these avengers who are not from the royal family will eventually use blood and bones as a chess piece to carve out a path of symbiosis that belongs only to them in the decaying palaces and temples.
