Tang Zhen asked a few more questions before letting the attendant leave.
The other party was just an ordinary person. Even if he knew more information, there was still a limit.
The only ones who truly knew the secret were the martial experts in the city. If Tang Zhen wanted to know more information, he would still have to find them and ask them.
However, his mind power was still locked on the waiter. He wanted to see what this guy would do after he left.
The waiter was very smart. He was arranged to receive martial artists here, so his duty was certainly not limited to his own job.
Collecting information was also one of his jobs. Customers asked him for information, but he was also observing the passing customers.
During the conversation earlier, Tang Zhen had deliberately revealed a lot of information. As long as this attendant wasn't stupid, he should be able to guess his background.
