At the same time.

Evidence Division of Luoyi Police Station.

After the War Ignorance Bureau informed the police of the military's information, the police's investigation of the robotic arm was reopened, and the Evidence Section launched a careful investigation of the robotic arm.

"How's it going?"

Yesterday, Qin Feng, who was in charge of Zhaojiacun, walked into the evidence department and asked about the situation.

At this time, two inspectors, a man and a woman, were busy in the evidence department.

Seeing Qin Feng enter the room, the male inspector looked up at Qin Feng and said frustratedly: "We have checked several sets of fingerprints, but I doubt they were left by the person who found the robotic arm."

"The robotic arm has been buried underground for too long, and the original traces on it should have disappeared."

Qin Feng frowned slightly, this is not good news.

Yesterday, he sent people to conduct investigations in Zhaojiacun and nearby villages. However, the results were not satisfactory.

People in the nearby area were completely unaware of the robotic arm, which basically eliminated the possibility of witnessing it.

If useful information cannot be found from the robotic arm, the investigation will come to a standstill.

Seeing Qin Feng's troubles, the female inspector on the side suggested: "How about making an announcement about the reward information?"

This is their regular police operation.

Work together.

Maybe we can gain something and solve the case.

Qin Feng did not agree with this proposal. The premise of offering a reward is that someone knows about it.

The problem now is that no one knows about the robotic arm.

"A program team has already admitted that they were responsible for the robotic arm. If we issue another reward, it will be very troublesome."

It's like slapping yourself in the face.

When netizens find out that they have been deceived, they will inevitably trigger a lot of criticism online.

There is absolutely no need to pay such a high price for a method that is basically useless.

Of course, even without the intervention of the War and Ignorance Bureau, the feasibility of this matter is very small.

The female inspector didn't say anything. It was really not suitable for this kind of thing in this situation.

After a moment of silence, the male inspector mentioned another matter: "It's not that we haven't discovered anything at all. The material of the robotic arm is an unknown alloy. If we can find out the source of this alloy, we might be able to find out something.

”

Special alloys have less circulation and are easier to investigate.

However, the premise is that you can find out which company the manufacturer is.

If they did it themselves, there would still be no chance.

"Please investigate."

A dead horse is a living horse doctor. It is better to try now than to give up.

Qin Feng immediately asked the male inspector to investigate the matter.

He himself has no suitable way to conduct investigation work in terms of alloy materials, and he does not understand special alloys.

It can only be left to professionals.

If the male investigator finds something, he will naturally follow up.

The other side.

Construction site awning.

"Show me."

After Lin Chen mixed the gypsum, he asked for yellow mud from Wang Jianbin and started working on it.

The process is not complicated.

Knead the yellow clay according to the shape of the pottery and stick it to the location that needs to be filled. Then, apply plaster on it to fill in the missing parts.

Finally, remove the yellow mud, scrape off the yellow mud stuck to the plaster with a knife, and then polish it with sandpaper.

The main thing is that when applying plaster, you need to pay attention. The resulting shape needs to restore the appearance of the missing part and cannot be like plastering.

Under his operation, in a short time, the missing parts of the pottery were completely filled with plaster.

What looks like a cement pipe stands in everyone's field of vision.

"Your guess is right!" Yang Mingyi said: "With this thing, it should be a residence over there."

He recognized the pottery that looked like a cement pipe.

Wang Jianbin was confused, what is this thing?

Why can it prove Lin Chen’s previous statement?

Others were even more confused and didn't understand what Yang Mingyi was talking about.

In the live broadcast room, Yang Mingyi's words made many viewers confused about the situation.

"What is this thing used for? It doesn't seem to be of any use."

"What do you mean? Can this really be proven?"

"Can anyone explain it to me? My brain is going crazy."

"Is it something extraordinary?"

……

Because it is so long ago, for most people, the Xia Dynasty is something that exists in myths and legends, and the actual situation is unknown.

Moreover, this pottery feels very strange, like a jar without a bottom.

What can this thing be used for?

Wang Jianbin asked Lin Chen: "What is this thing?"

He thought for a long time but still couldn't figure out what the thing in Lin Chen's hand was.

"A piece of water pipe." Lin Chen said.

This is the prompt the system gave him after he completed the repair.

This thing is an underground water pipe.

If the system prompted him, he really wouldn't be able to guess it.

"Water pipe?"

Wang Jianbin exclaimed softly, the result was far beyond his expectation.

The Xia Dynasty actually had water pipes?

Are you sure you're not kidding me?

Not only him, but most people in the live broadcast room were also in disbelief.

That was the Xia Dynasty four thousand years ago, not now.

It’s hard to believe that at that time there was already a drainage system and even underground pipes.

"Fool, keep fooling, if you believe a word, I lose."

"You are so good at pulling underground pipes. None of the three countries may have such things."

"It's not that I don't believe you, brother, but you are a bit insulting to your IQ."

"I don't think it's impossible. The wisdom of ancient people is no worse than ours. There are many things that cannot be reproduced with current technology."

"Anyway, I don't believe it. This thing could have existed four thousand years ago, and I was still the richest man in the world!"

……

"You mean the kind of water pipe we use, the kind that transports tap water?"

Wang Jianbin said while pointing his hand at the water pipe. It is undeniable that the appearance of the pottery is somewhat similar to the water pipe.

But he always felt that this matter was a bit outrageous.

"That's right, but it's for sewage discharge."

In ancient times, there were not so many machines as today. This pottery is indeed a water pipe, but its purpose is relatively simple.

Judging from the information given by the system, this thing is buried underground and used.

It is matched with the water channel, one light and one dark, to jointly deal with the problem of sewage.
