After the planet's area suddenly expanded tenfold two thousand years ago, all native species except humans mutated. Animals and plants mutated and developed various abilities. Trees could uproot and attack, tigers could grow wings, and there were countless others such as breathing fire and controlling the wind. Since then, the status of the food chain has been greatly reversed, and humans who were originally at the top of the food chain fell to the bottom.
In desperation, people discovered the spiritual beasts that appeared together with the strange beasts. From then on, the contracted spiritual beasts became spiritual beings, opening up secrets to communicate with the world and evolve together with the spiritual beasts.
People here can only contract one spiritual beast in their lifetime, but Cheng Chu, who traveled through time, found that he could contract two.
"Since the Snow Wolf can evolve into the Immortal Moon Wolf King, and the Butterfly can evolve into the Flower Fairy, then it is very reasonable for my Spirit Turtle and Spirit Snake to combine and evolve into Xuanwu," Cheng Chu said to his system.
Mission: Life is endless and evolution continues
