Master Doctor in the City

After Ye Chen put on the work clothes of the staff member, he swaggered around inside. He found that this household garbage incineration plant was very developed. As for the domestic garbage incineration plants, he had not seen it, but this garbage incineration He thinks it is not simple.

According to these fully automated and mechanized garbage disposal machines here, a lot of garbage will be processed every day.

After reading it again, I found that there was nothing special. When Ye Chen came out from the inside, he saw No.3, the two members of the Fuqing Gang, who had also worn the uniforms of the staff here.

"Separately act to see what is suspicious. If you don't find it, assemble at three o'clock in the morning. If you encounter an emergency, protect yourself."

After Ye Chen made it clear to them, they started to split up.

Since the tap water is polluted here, there must be a problem with it.

However, I haven't found the problem yet?

When Ye Chen went to the domestic sewage treatment plant alone, he walked for about ten minutes before he came here. The domestic sewage treatment plants here are also all automated and mechanized. They use a lot of domestic water every day. All industrial sewage is directly transported here through pipelines, and after treatment, it is directly discharged through a river.

Ye Chen discovered that the treated sewage was processed inside and then discharged directly to the river outside. Now that river is very clear, and you can see many fish swimming around there. This is very smelly with the domestic ones. The river is completely different.

When Ye Chen walked around in the sewage treatment plant again, he found that there were not many employees inside, about a dozen people, all of whom were managing their own machines. At other times, they might be bored reading or Do other things to kill time.

Now Ye Chen looked inside and found nothing special at all. Could it be that the water discharged from here contaminated the tap water.

However, the treated water here is directly discharged into that river, and that river may flow to the sea. In this case, the tap water that other citizens drink is definitely not this water.

Then the polluted tap water should be connected to the tap water pipe or leaking.

But where is the water pipe passing through here? Ye Chen couldn't see it temporarily.

After reading it a few times, Ye Chen didn't find any problems. He went outside and encountered No. 3, and No. 3 found no other problems.

"Master Ye, I didn't find anything suspicious."

After the two Fuqing gang members came back, they did not find anything suspicious. They were just a large-scale domestic waste incineration plant and a large-scale domestic sewage treatment plant. They were built together because they were In addition, a large amount of industrial water is needed in the process of the waste incineration plant of the same company, and the domestic sewage that has been treated can be used to cooperate with the waste incineration plant.

"Do you know where the tap water pipe is?"

Ye Chen looked at the two Fuqing gang members and asked.

"These tap water pipes are usually in the sewer."

sewer?

This kind of underground passage is different from the small-scale underground passages in China. The large cities in China are not well planned. The underground passages use circular pipes with a diameter of half a meter or even a meter for drainage, or some domestic water is discharged. Used by the river.

However, Japan’s sewers are very large and can be passed by a large truck. Therefore, no matter how heavy the rain is in the big cities on this side of Japan, there is no possibility of flooding, because the water will soon be discharged through the sewers. The river may be discharged into the sea.

Ye Chen didn't expect that the tap water pipe here was actually under the sewer.

"Can you find it here?"

"it should be OK."

Obviously, part of the domestic sewage treated here is directly discharged through the river above, and the other part is discharged through the sewer to the big river.

However, now we have to find that intersection and go down.

Ye Chen and No.3, following these two Fuqing gang members, traveled a long way in this company, but they didn't find the entrance and exit of the sewer.

The two members of the Fuqing gang felt that they must be inside the company. As for the outside, they could certainly be found, but they could only be found after a long distance.

Now they can't find it, they can only ask the person inside.

Now there are other staff members in it, so you can just ask them.

The four of them returned to the domestic waste incineration plant and went inside. No.3 and the two Fuqing gang members went directly to a staff member.

The staff member was looking at the data on the machine. He didn't know that these three people were no longer his colleagues. Suddenly he covered a Fuqing gang member with his mouth, then looked at him and said in Japanese: "Don't talk if you don't want to die."

The Japanese nodded hurriedly.

"Do you know where the entrance to the sewer is?"

The other party has been working here for so long, so he naturally knows where the entrances and exits are here, and usually he might have to go down and take a look.

"Now take us over."

The Fuqing Gang continued to speak in Japanese.

The other party could only take Ye Chen and the four people to the entrance and exit of the sewer. When they got there, Ye Chen had already heard the sound of running water below. He might not have heard it just now. It might be because of the working machines inside. The sound was so loud that Ye Chen and the others didn't even notice that the entrance and exit of the sewer was here.

"Follow us down."

The Japanese staff member does not yet know who these four people are, and when they see them wearing masks, they can't recognize the identity of the four.

As for the work permits held by these four, the other party must know that they are fake.

While walking down the stairs from the top, Ye Chen discovered that the sewer was coming down from above. It was almost eight or nine meters high, which was already three stories high.

When he reached the bottom, Ye Chen discovered that this long sewer channel gave him a sense of shock.

Below this, the height may be eight or nine meters, and it is almost a semi-elliptical sewer. This kind of place is probably only visible to the subway in China.

No matter how heavy the rain is on such a large sewer, when it is directly drained, there will be no flooding in the city.

"Is there a sewer like this in every city?"

Ye Chen asked.

"More than that, there may only be one in a small city, but a few in a big city, a dozen are possible, like Tokyo, except for the densely packed subway lines, then there is this kind of sewer."
