Zhang Yuchen was still weak, so Mao Jing and I dragged him forward through the water.
At the same time, we watched the outlets of the underground pipes along the shoreline.
There were several of them, and they were all fairly large.
Mainly because there was a sewage treatment plant here.
Most of the wastewater from the Edo area was diverted here, purified, and then discharged into the sea...
It had not rained recently, so the drainage volume in these underground pipes was not very large.
Following Brother Wang's instructions, we deliberately stayed out of sight of the people on shore.
From the sea, we entered one of those massive sewage pipes.
Once inside these pipes, we could enter the sewer network beneath the entire city, evade the Japanese pursuers, and hide ourselves.
As soon as we reached the shore, we saw police cars patrolling nearby.
We did not know whether they were looking for us, but we remained alert, exposing only our eyes above the water.
We continued forward only after the patrol had left.
After entering the sewer network, we began making our way deeper inside...
The pipes were huge, at least two meters high, and extended far into the distance.
As we continued forward, more and more branching pipes appeared around us.
I had once read a report saying that the underground sewer network beneath Edo Castle in Japan was extremely complex.
It was normally used for sewage disposal, but in wartime, it could serve as an underground fortress.
Seeing it today, that really did seem to be the case.
"Is this really a sewer? Why does it look more like an underground transit network?"
Pan Ling asked in surprise.
Before I could answer, Aoi Yui spoke first.
"Yes. Edo's underground sewers are enormous and densely interconnected.
