"What's behind these cracks?"
Meng Chao thought for a moment. The reason why these sewage pipes were abandoned was that after hundreds or thousands of years of use, the sewage and groundwater had been leaking for a long time, resulting in a weak structure. Some of them had collapsed and blocked all the pipes.
However, other than the collapsed section of the pipes, the pipes farther down should still be intact.
The second collapse that he had created was very likely to unblock the blocked pipe.
At the very least, it would open up a few palm-sized cracks.
If that was the case, the secret hidden deep underground at the end of the pipe might be exposed.
Hence, the Rat God's emissary had asked someone to patch up the cracks.
Thinking of this, Meng Chao raised the iron rod and inserted it into the cracks that had just been patched between the broken walls.
