The sudden noise naturally startled Zhou Tian at that moment, but although the sound was loud, the roar of that Treant itself was not enough to harm Zhou Tian.
And because under normal circumstances, the roar of that Treant posed no threat to him, even though Zhou Tian was momentarily startled by it, he did not react.
However...
While under typical circumstances, the Treant's roar couldn't harm Zhou Tian, this did not mean the roar had no effect at all. In fact, just when Zhou Tian breathed a sigh of relief, thinking the Treant's roar had concluded without consequence, he hadn't anticipated that the seemingly ordinary loud roar possessed some other Ability.
Right when Zhou Tian wasn't paying attention, soon after the sound waves landed on him, they immediately began to take effect.
"Roar! Roar! Roar!"
