In the interstellar era with strict ABO hierarchy, Enigma, as a walking pheromone bomb, was born bound by a restraining collar and a marriage contract. Xie Chengyuan, the only Enigma heir of the Xie family, has a black crystal necklace around his neck that contains the traces of uncontrolled melting when he separated at the age of sixteen, but he sees an opportunity for revenge in the marriage contract - his marriage partner is actually Jiang Lin, the youngest Alpha Major General in the military.
Jiang Lin, the carrier of the red flame cedar pheromone, appears to be an iron-blooded warrior, but in fact suffers from congenital pheromone sensory overload syndrome. He is only unusually sensitive to Xie Chengyuan's entropic pheromone. When the two people's pheromones collided for the first time, the resonance of red flames and entropy not only triggered the highest security alarm, but also tore apart the secrets that the interstellar power class had covered up for twenty years.
The clues to the "Altar of Entropy" discovered by Xie Chengyuan in his mother's belongings and the Enigma disappearance investigation file left behind by Jiang Lin's father pushed this expedient marriage into an undercurrent. While they have to deal with the surveillance of the family and the conspiracy of the Entropy Hengsi, they gradually get closer to each other's souls in the chaotic resonance of pheromones. When Xie Mingxuan's deadly trap and the assassination of the Bone Corrosion mercenary group strike, can Red Flame and Entropy break through the shackles and find the free fire belonging to Enigma in the storm of pheromones?
Purpose: Breaking labels and prejudice: The story shows the prejudice and oppression of minority groups through the encounter of Enigma, a special group. Xie Chengyuan and Jiang Lin join hands to fight against the shackles of tradition, revealing that individual value should not be defined by innate attributes, and calling for respect for differences and the elimination of discrimination.
