Zhou Tian's strength need not be mentioned, terrifyingly strong from all aspects. Before journeying to the Divine Realm, in the Lower Realm, he supposedly should have no opponents.

Zhou Tian had relentlessly attacked the opponent without success; although it appeared that his situation hadn't changed, under that circumstance, Zhou Tian knew that if the battle were to continue for much longer, it would not be good for him.
