As soon as the Time Domain was activated, the actions of those NPCs at that moment slowed down considerably. In that context, Zhou Tian and the Bearman at the city gates launched a simultaneous attack against those NPCs. The NPC group at that time had no chance of withstanding such an assault.

And so, countless Bearman rushed directly into the sacred city through the path Zhou Tian had opened.
