During Zhou Tian's inaction, there were simply too many monsters to deal with. Apart from formidable BOSSes like the Puppet Maker, an existence such as Zhou Tian was not yet noteworthy enough to attract the attention of the NPCs. But once Zhou Tian took action, those NPCs could no longer ignore him.
A BOSS is a BOSS, after all. Even though Zhou Tian's power wasn't top-tier among the BOSSes in the beginner area, his destructive capability still surpassed that of ordinary monsters. Therefore, when Zhou Tian launched an attack against the city wall, the NPCs naturally had to step in due to the powerful destructive force he displayed.
Despite the NPCs' attacks, Zhou Tian paid them no heed. He single-mindedly hacked away until his HP dropped to less than half. Only then did he finally see the city wall's HP reach a critically low point.
Finally, as Zhou Tian made a full-strength swing with his axe, he shouted to the monsters behind him, "The wall has fallen, everyone charge!"
