Students from the Martial Arts Academy would improve very quickly after being tortured by a first-stage Martial Saint Grotto-Heaven realm vicious beast every day! Moreover, this vicious beast had recently advanced to the second-grade Grotto-Heaven Realm.
Later on, the other Martial Arts Academies heard some news. Soon, some smart people sent their outstanding students to the Martial Arts Academy of the Wilderness to learn.
There were also some who simply formed teams and came to the Wilderness border to train. They were dragged out to fight with vicious beasts. Whether they lived or died depended on their fate.
Cow's actions greatly increased the combat ability of the Northern Kingdom's Martial Arts Academies. Wang Xian also quickly advanced to the Martial Saint realm.
