It would have previously been impossible for Mo Wen to be so powerfully without using spiritual weapons and other magical treasures. However, after practicing all his martial arts teachings to the highest levels, his combat power had already grown by an alarming amount. He was now easily able to kill monstrous beasts of the same realm as him just through physical fighting.
The powerful later stage seventh rank monstrous beasts that Mo Wen was now facing were mere pushovers.
As time passed, more and more monstrous beasts died at his hands. His cultivation became higher and deeper, gradually returning to the level he was at when he killed Hou Jingfeng. If he continued to slaughter all the monstrous beasts he came across, it would most likely not take long for him to break through to the intermediate stage of the Golden Elixir Realm.
