"Rats? As in rodents?"
Li Zhou had been about to pour himself a fifth cup of Cloudmist Tea when he suddenly spoke up.
Kong Yue shook her head.
"'Rats' is just what we call them."
"They're actually people who specialize in damaging feng shui formations or exploiting their weak points to bring in yin cultivators who can't otherwise enter the Ghost Market."
Chen Miao asked in confusion, "If those rats can find the loopholes, can't the Demon-Suppressing Bureau?"
Kong Yue said helplessly, "Of course it can."
"But do you know how long it takes those rats to find a loophole and open it up into a passage?"
Kong Yue held up three fingers.
"At least three years!"
"The Demon-Suppressing Bureau has caught a few rats before. Three years was the shortest time any of them took."
"Of course the Demon-Suppressing Bureau could send people to do this. But the problem is, after spending three years finding a passage through a loophole, can you be sure it's the same hole those rats found?"
"What if we spend three years finding and patching a hole, only to discover that the rats and the Demon-Suppressing Bureau weren't using the same route at all?"
"And plugging every hole is simply impossible."
"The Demon-Suppressing Bureau doesn't have that many people, nor does it want to waste manpower on this."
"So all we can do is lie in wait!"
As she spoke, Kong Yue took out her token.
"Our tokens have been specially modified. When you suspect someone, you can activate your token to make it communicate with the Ghost Market Pass on them. If it can't establish contact, that means there's something wrong with that person."
Li Zhou's eyes lit up.
"Then couldn't we find them just by checking everyone with our tokens?"
Kong Yue
