First, because Zhou Tian detonated a large number of crystal bombs at that time, the explosion directly led to the near obliteration of all nearby plant enemies. In such a scenario, if Zhou Tian truly wanted to escape, those plants naturally wouldn't have any effective countermeasures to stop him.
Moreover, just as Zhou Tian executed his plan to this extent, after he shattered the head of the Treant, an unexpected change occurred that Zhou Tian had never anticipated.
Right after the Treant's head was destroyed, to Zhou Tian's astonishment, the initially regenerating plants instantly turned into ordinary lumber. Even the plants that were not affected before gradually turned into ordinary plants. Thus, with all plants undergoing such transformation, Zhou Tian no longer needed to worry about those plants posing any threat to him.
