Beijiang had never relaxed their surveillance of loucheng, for fear that this mysterious city would suddenly cause trouble.
However, until now, the information about loucheng was still in a state of confusion.
Most of the cultivators in the northern border knew nothing about Lou Cheng's origin and background.
The higher-ups of the northern border camp might know some secrets, but they would definitely not disclose them.
If there were no accidents, they all knew about the existence of the upper realm and might even associate Lou Cheng with it.
The more he thought about it, the more he didn't dare to act rashly.
At this moment, in the city Tower, an armed airship slowly rose into the air and flew quickly in the direction of the northern border.
The moment they left loucheng, the armed airship was monitored, and a hidden northern border cultivator reported the news.
