The ancient Zhuolong died, and the plague seeds were scattered, turning into an incurable "blood plague curse".
Bai Wanzhi, Bai Yueguang who died young in the past, was resurrected by the system. He has the only antibody in his body, but his mission is to conquer Pei Qianzhu, the born demon fetus - his bones and blood can suppress plagues and destroy the world.
Pei Yinzhu has been imprisoned at the bottom of the whale bone since he was a child, with chains pierced through his bones, and he takes blood to make elixirs every day. The world fears him like a disaster star, but they don't know that he is also the last prison of the plague species.
In front of the Dragon Sacrifice Monument, Bai Wanzhi mistakenly stained the monument with the blood of the antibody, and the seal was shaken. He asked himself to apologize and knelt beside the monument. Pei broke out of the cage with a candle in his hand. The black and blue chains broke inch by inch, blood spattered the dragon pattern, the plague seeds resonated, and the color of the world changed.
After that, the two formed a twin contract: she carved a seal in her bones, and he imprisoned the doomsday in blood. They share the same vein of life and death, and love and hate share the same blade. The Immortal Sect wants to slay the dragon again to save its life, the plague seed wants to use the body to revive, and the world is about to fall into chaos.
Bai Wanzhi drew his sword to guard the world, while Pei held the candle and used the reverse scale as a sheath to lock the plague seed and himself into the abyss.
In the end, she stands on the top of the whale bone, watching the clear sea and river; he lies at the bottom of the dark abyss, listening to the sound of the tide like her heartbeat. She guarded the world, and he guarded her - until the plague was gone and the dragon's roar ceased.
