When humanity first arrived.
The initial threat faced was not the mysterious races of the heavens, but rather the native demon beasts.
These demon beasts were powerful, bloodthirsty, and had extraordinarily strong reproduction abilities...
Almost impossible to kill off completely or eradicate.
It took humans several decades, especially with the rapid advancement in Martial Tao, for their strength to soar to new heights, finally driving these demon beasts into the largest inland areas of the Original Blue Star.
Then they set up fortresses to halt their counter-charge.
These places became known as the Miwu Ghost Forest, Ice Snow Realm, Desert Sand Realm, Lava Mountain Pass, and so on...
Not long after that period of peace.
The mysterious races of the heavens invaded.
Humanity faced an even greater crisis, and it was at this time they realized that the warriors they had trained were actually like flowers in a greenhouse, untested by frost and snow.
