In the Fantasy Beast Continent, people contract fantasy beasts to fight for themselves.
There is a giant dragon hovering in the sky, causing violent storms.
There are fire and phoenixes that start a prairie fire, and spread their wings to stir up meteors and volcanoes.
Yun Feiyang, who vowed to avenge his parents, summoned the weakest pastoral dog as his first phantom beast during the contract ceremony.
However, as time passed, Yun Feiyang discovered that the big yellow dog was a mutant and could evolve itself infinitely.
It has awakened the most powerful phantom beast system and can see through all beasts.
