The ground that Kim Hajun punched with his fist cracked and destroyed until it become a giant hole on the surface of the earth whose depth almost reaches the bowels of the earth.
Kim Hajun himself did not expect that his dimensional punch could give such a terribly destructive effect because this was the first time he had used his dimensional punch to punch the ground.
However, in reality, Kim Hajun's dimensional punch didn't have that much destructive effect because the real cause of the ground that Kim Hajun punched with his fist cracked and destroyed until it become a giant hole on the surface of the earth whose depth almost reached the bowels of the earth was the path that has been made by the mutated earth centipedes from the bowels of the earth to the surface.
Kim Hajun could see the corpses of the mutated earth centipedes left in the ground along with the traces of the paths made by them.
