After agreeing to participate in the operation, Tang Zhen did not gain more trust. Instead, he was under even stricter supervision.
The cultivators of Lou Cheng did this to prevent Tang Zhen from coming into contact with cultivators from the outside world and leaking important information.
Tang Zhen had already discovered that there was a high-level cultivator monitoring the inside and outside of the city. Nothing could escape the other party's perception.
Even if Tang Zhen's main body were to personally come and attempt to enter the tower, there was still an extremely high chance that his whereabouts would be exposed.
Under such circumstances, Tang Zhen, who did not want to attract attention, had to be even more careful when he was tempted.
At the same time, Tang Zhen finally confirmed that the huge ships that were being built were in preparation for this sea operation.
The day the ship was built was the day the operation began.
