In the supermarket, a tiny figure was pushing a shopping cart that was much bigger than him and moving around quickly.

"Red dates, red dates nourish the blood~~"

Several large bags of red dates were quickly swept into the shopping cart.

“The rest are all snacks!!”

With a shout, the shopping cart rushed to the snack area.

Tao Xingzhi looked at Doudou with some surprise as he passed by.

'Whose kid is this, going crazy in the supermarket...'

I looked around but didn't see any adults. I guess they are from nearby residents. It's really generous of them to let such a young child go shopping alone.

However, Tao Xingzhi had neither the mood nor the energy to think about cases such as kidnapping. These "little things" were insignificant compared to the pressure he was facing now.

He put a few boxes of gum and cigarettes into the shopping basket and turned to the cashier to pay.

This was his third time in Yuecheng in a short period of time, but this time he just passed by and came to understand the situation.

The golden period for solving the river incident had long passed, and although the telephone booth destroyed in the explosion was found, no valuable clues were extracted.

The only thing that is of some use now is the recording of the call to the police.

But this is the same as extracting fingerprints from a crime scene. The large population makes it impossible to establish fingerprint and voiceprint files. You can't find a needle in a haystack by asking everyone to check it.

Normally, fingerprints will be extracted for testing only when a "criminal suspect" is identified. Now in China, only people who have committed crimes are included in the fingerprint database. As for the voiceprint database, wake up.

The detection of voiceprints is even more complicated. There are only a few testing agencies in China. They only rely on the naked ears and the crappy receivers of old phones to record. Even if the person who made the call is standing in front of the person who has heard the recording, the voice will be ignored.

Unless the person calling the police has very obvious language characteristics, which obviously does not exist.

Of course, there is another way to look at the sky.

If another obvious abnormal incident occurs in Yuecheng or nearby, and the mysterious existence takes action again, this may be more effective than the last investigation, but it is just a thought. Tao Xingzhi hopes that no abnormal incidents will occur in the whole country.

After leaving the supermarket and getting in the car, the colleague in the driver's seat took the chewing gum handed to him by Tao Xingzhi.

Relieve stress and fatigue by chewing.

"Boss, why are you still going to the Yuecheng Municipal Committee?"

Tao Xingzhi hesitated for a moment. It would take half a day to go there, so this time he just came to take a walk around the "crime scene".

"No, I'll go directly to Jiacheng to see the construction site."

"good!"

The car started, revealing Doudou carrying two large shopping bags. There were some red dates at the bottom of one bag, and the remaining one and a half bags were basically all snacks, which were rewards from her eldest cousin.

"The smell of that person just now... who cares!"

Doudou sniffed.

Tao Xingzhi's long-term exposure to strange crime scenes, or contact with people or objects involved in many similar incidents, has left some special smells on his body that are difficult to wash off.

It may not be a big deal in Magson or other worlds, but it is particularly prominent in the Earth world, which is not a good phenomenon.

However, Doudou did not choose to go up and remind him of anything based on the principle of "it's none of my business".

After driving for two hours, this ordinary Passat arrived at a construction site surrounded by a large retaining wall in the far suburbs of Jiacheng.

There is actually an armed police checkpoint outside the construction site, which is unique among construction sites.

The car stopped at the entrance for visiting guests.

A paramilitary soldier came out of the sentry box and saluted the car.

"Comrade, please show me your ID!"

Tao Xingzhi and the driver Xiao Liu returned the gift as usual and each took out their ID and handed it over.

Although the armed police on duty did not know what department the certificate referred to, they could tell at a glance that this was one of the highest-level certificates in this inspection mission.

The armed police handed the certificate back and gestured with his mouth and hands to the person behind him.

“Let him go!”

…

Once you enter the construction site, without the blocking of the dedicated soundproof wall, the noise of construction is many times louder than outside.

The rumbling sound of large machinery was everywhere.

Earth-moving trucks passed by one after another, as did the material trucks.

A huge section of alloy pipe wall is slowly being lowered by three large tower cranes. Its volume is large enough to hold at least several heavy trucks.

Below is a huge tunnel, and no one knows how deep it is.

Completely different from looking at drawings and videos, only by coming to the scene can you experience the violent aesthetics of this mechanical steel.

This made the two of them stare at each other for a long time.

The two parked their car in a special parking lot.

Go straight to the cabin where the construction workers and on-site designers are.

Huang Jiutian is checking the drawings with the general manager.

As one of the main design and construction units, it is impossible for Huang Jiutian's company to be without a designer on site.

Jiutian's initiative to volunteer made everyone in the design department very grateful to him.

After signing a thin confidentiality agreement, Huang Jiutian became one of the on-site designers at the Jiacheng construction site.

Although the agreement was very thin, its force was extraordinarily strong. Huang Jiutian felt that if he did not have a mysterious supernatural force behind him, he would not only be imprisoned for life if he dared to leak it.

During his stay, all his personal communication devices and online social accounts were briefly confiscated, but were quickly issued again.

But insiders basically know that these things are now being monitored.

Industry insiders with a keen sense of smell, such as Huang Jiutian, understand that this so-called civil air defense project is by no means ordinary, and it goes far beyond the ordinary in terms of scale and use.

Facilities of this level were only possible during the Cold War.

But ordinary construction workers just receive a high salary, and civil defense is just civil defense.

“At this angle, I suggest installing a sliding frame underneath, which can avoid further excavation of the upper soil layer, improve accuracy, and free up the working space of the tower crane.”

"If we set up sliding, installing the structure frame under the soil is a difficult task in itself, which is more labor-intensive and time-consuming. Have you considered this?"

Jiutian pointed to the notes below the drawing.

"That's true, but this project is based on the premise of ensuring the integrity of the surrounding geology as much as possible, and it is clearly stated that no matter the cost, I think the time and effort are not a problem in terms of project quality."

Several other designers also joined the discussion.

This group of people definitely saw Tao Xingzhi and Xiao Liu, but no one paid any attention to them and just left the two of them aside in awkward silence.

Tao Xingzhi and Xiao Liu looked at each other, then stayed tactfully and didn't say much.

Although the two were laymen, they had read the engineering information countless times, so they could actually understand some of it.

The discussion ended only when a senior leader of the construction site heard that a special commissioner had arrived and came into the office.

Only then did everyone realize that the two people sitting there smoking alone were important central envoys.
