The reason those forces initially used such simple tactics against Zhou Tian was primarily because they did not want to waste much time on him. After suffering a quiet loss at the beginning, their only thought was how to capture Zhou Tian, this enemy, in the shortest possible time. And under those circumstances at the time, those forces did not seriously consider how to deal with Zhou Tian.
Secondly, those forces indeed held an absolute upper hand in strength. Even under those circumstances at the time, they were confident that they could easily crush Zhou Tian, this enemy, just by pushing forward without using other tactics.
As a result, without the intention to seriously fight Zhou Tian while also holding the advantage in strength, those forces naturally reacted in that manner.
