The inhabitants of this world can't cultivate and have to rely on their racial advantages. But there are some special creatures that were born with innate super strength.
The special creatures were born by world guardians. These creatures inherited a part of the power of their parents and can easily reach rank 4 in power. This makes them more than capable of killing the rank 4 cultivators.
There are also a lot of these special creatures because of the long history of the world and the proliferation of the bloodline of the world guardians. There are millions of these special descendants and thousands of them at rank 4, which makes them an army that outnumber the rank 4 cultivators 10 to 1.
The descendants of the world guardians were sent after the rank 4 cultivators, while their ancestors, the world guardians, were sent after the rank 5 cultivators. As a result, every invader was being hunted by the world.
