Intro. In the continent where humans and beastmen coexist, life is governed by blood and spiritual energy. After forming a mate contract, the female will become pregnant according to the characteristics of the other species. As for the snake spirit, it can only form a spirit egg when the spiritual energy of both sides truly fuses, going beyond the constraints of the contract to become a complete resonance. Linh Uyen smelled the scent of her spiritual energy as soon as she entered the Beastman Center. He believes she will choose him. But when she stops in front of another, her territorial instincts explode. Linh Uyen wrapped himself around her, using his blood and venom to force a contract. That night, she had a severe fever, and he curled tightly around her, not letting anyone get close. From then on, Linh Uyen's world only had one person left. He was not in the cage, just wrapped around her, eating the fruit she planted, jealous of every eye that touched her. When mature, estrus comes like a storm, the snake's instincts point towards her. But she is still not pregnant.
