In a parallel world where superpowers and beasts coexist, Xiao Ye is an "alternative" who appears to be self-denial but is actually extremely possessive. The "Abyss Contract" power he awakened was able to sign a soul contract with an ancient beast in the abyss. However, behind this seemingly powerful ability, there is a fatal curse: the stronger the contracted beast is, the greater the backlash will be.
It wasn't until his pursuer Su Wan appeared. This girl, who was gentle on the surface but twisted inside, used her powers to control strange beasts to assassinate him, did Xiao Ye realize that he had been involved in a conspiracy that spanned ten years. Everyone is coveting a certain secret in his body, and that secret may subvert the rules of the entire world.
In order to survive and control everything, Xiao Ye began to frantically contract with strange beasts, from the abyss python to the immortal phoenix, from the frost dragon to the void master... Every time he contracted with one, he had to endure the pain of soul tearing. But he didn't know that with every additional contracted beast, he would be one step closer to the Throne of the Abyss.
When he finally stood at the peak of his powers, he discovered that a greater crisis had come - the Su Wan who had been chasing him was actually the Princess of the Abyss who was sealed by him in his previous life. And what she pursued was never him as a person, but the "seed of destruction" in his body...
