With the threat of those magic crystal weapons eliminated, breaking into the enemy's city would not pose a difficult task for Zhou Tian, given his strength.
As a result, once Zhou Tian discovered the situation with the enemy's main city, he certainly could not miss such an excellent opportunity. Thus, once such a thought occurred in Zhou Tian's mind, he decisively chose to take action against those NPCs.
Everything progressed very smoothly. The main reason those NPCs had previously managed to keep Zhou Tian out of the city was because as soon as Zhou Tian approached, the NPCs would immediately launch attacks, using the destructive power of their magic crystal weapons to prevent Zhou Tian from nearing their city.
