Given the situation at the time, as long as Zhou Tian managed to weaken the opponent's Defense Power, dealing with them subsequently wouldn't be difficult at all.
Zhou Tian's strength was evident. Although initially, he had no way of handling the lion creature, this did not mean Zhou Tian's strength was weak. The main reason he couldn't Attack and Break the opponent's defense was not that his attack was weak but rather that the opponent's Defense was incredibly strong.
At that moment, even if Zhou Tian initially couldn't break through the opponent's Defense, once the lion's Defense Power began to weaken, Zhou Tian's subsequent attacks became enough to pose a threat to the creature.
