Kim Hajun used his dragon fang slashes vertically and horizontally to slash those mutated earth centipedes until almost none of them remained.
Kim Hajun landed on the ground and the few remaining mutated earth centipedes went back into the ground.
Kim Hajun naturally didn't accept it when those mutated earth centipedes returned to the ground.
He didn't accept it at all when those mutated earth centipedes chose to run away from him and didn't face him until the end.
Kim Hajun walked towards where the mutated earth centipede reentered the ground and there he could see that there were some deep holes.
Kim Hajun entered the hole in the ground made by those mutated earth centipedes.
Kim Hajun is in free fall and the air around him becomes more humid and warm.
He kept falling until he finally saw a light from below him and he also felt that there was very hot air coming from beneath him.
