If the number of laboratories is limited and they are all built under natural fortresses like the Dong Family's, it would be extremely difficult for Xu Huo to enter, but if there are such places within the city buildings, then it would be much easier.
Of course, such places are not necessarily where Doctor Zhang's cultivated children go, but trying one's luck might work too.
"All the water usage records of companies and residences in the city should be found at the Water Supply Bureau, and constructing a separate water system in the city is not easy, so whether it's a company or other places, the water consumption should match the actual usage," Xu Huo said. "Even if records from years ago are gone, the water usage of a company should roughly match that of another company of the same size. Any significant discrepancies could indicate that the building has some hidden water consumption."
