Zhou Tian, though also a King Level BOSS, was not bragging when he said that, compared with the average monster of the same rank, his strength was indeed significantly stronger at the moment. Relying on Zhou Tian's strength alone, just by approaching, he could have scared off the opponents who were fighting with Bella and her companions merely through intimidation.
Indeed, that was exactly what had happened. It wasn't just Zhou Tian; with the combat power of Bella and the other King Level BOSSes, the presence of any other entity of the same echelon would have already been sufficient to change many things at that time. Thus, with Zhou Tian's fame, once he appeared within the perception of those fighting with Bella, one could imagine how unlikely it was those monsters would dare to stay put and wait to be surrounded and attacked by Zhou Tian and Bella's group.
