The train driver in the courtyard

Digging a cellar is a huge project.

Li Aiguo originally planned to spend two or three months to complete it.

Unexpectedly, things took a turn for the better on the fifth day after the official excavation began.

Li Aiguo picked up the steel drill and dug it into the soil as usual, and heard a clanging sound.

Did you hit the brick?
Li Aiguo changed direction again and hammered the steel drill in, and there was another clang sound.

This is really weird.

How come there are so many bricks buried half a meter underground?

Li Aiguo changed direction several times and all he could hear was clanging sounds. Then he realized that there were no broken bricks below, but something like a wall.

"Have we dug up an ancient tomb?" Chen Xueru also became excited at this time, and the flashlight beam waved around on the ground.

"Bring me the shovel."

Li Aiguo reached out his hand from the hole, took the shovel, dug up all the loose soil on the ground, wiped away the broken soil underneath with his hand, and what came into view was a brick wall.

"It's a brick wall up and down. I don't think it's an ancient tomb."

Li Aiguo breathed a sigh of relief.

According to regulations, construction work must be stopped once cultural relics and ancient tombs are discovered at the construction site. He was just hesitating whether to report this, but now it seems that it is no longer necessary.

The blue bricks had been underground for some years. Li Aiguo picked up a steel drill and chiseled a hole in it in just a few strokes.

He waited for a while, then lit the lighter and reached in. Seeing that the flame was not extinguished, he crawled into the hole.

With the help of the flashlight beam, it can be seen that this is a secret room. The secret room is more than two meters high and covers an area of ​​about ten square meters.

The original entrance to the secret room was located on the east side. Li Aiguo estimated the distance and deduced that the entrance should be in the cellar of the courtyard.

It seems that this is a secret room set up by the dignitaries who lived in the compound in the past.

As to whether it was a high-ranking Tartar official or someone even more senior, Li Aiguo couldn't figure it out. After all, the houses in the capital had changed hands too many times.

Each force takes turns to take the stage, and anyone can leave a little trace.

Li Aiguo was a little excited at this time.

The secret room is always associated with treasure.

If you can find some small yellow croakers, you will be rich.

Unfortunately, after walking around the secret room three or four times with the flashlight, Li Aiguo realized that he was overthinking.

The secret room was empty, with the only objects being a few large jars containing traces of wheat and rice.

The reason why they are called traces is that after a few years, the wheat and rice have turned into black dots under the ravages of time.

However, Li Aiguo was not particularly disappointed.

The value of this secret room is more than a few small yellow croakers.

A secret room the size of a house, if filled with food, would be enough for a dozen people to use for three years.

Of course, before the secret room is officially opened, the official entrance must be sealed.

"Find some more bricks and pile up that side and it will be almost done."

After making up his mind, Li Aiguo crawled out of the secret room.

Chen Xueru was also very happy when she learned that there was a secret room downstairs.

"This way we can save a lot of effort. If we don't have antiques, then we don't have them. They are not worth eating or drinking."

Miss Chen is also a contented person.

In the following days, Li Aiguo used old bricks to seal the entrance on the east side of the cellar. He deliberately added a layer of soil on the outside of the bricks. Even if someone found the entrance in the cellar, they would only see yellow soil.

The entrance to the cellar was located under a cabinet and covered by a thick wooden board. After covering it with the board, Li Aiguo moved the cabinet back to its original position and blocked the board tightly.

"The next step is to store food."

"When spring comes, take He Yushui to the suburbs to dig wild vegetables. They can be dried and stored for a year without going bad."

"I plan to replace all the fine grains this month with coarse grains, and then have Wang Da Kui buy some grains at the pigeon market."

"People can't live without meat. Drying meat here is too conspicuous. After a while, I will get a big fat pig and send it to Weizhuang Commune, so that they can help make it into bacon."

Li Aiguo is not short of money now. Not counting the money he earns from his business partnership with Wang Dagui, his monthly salary is more than 100 yuan, and his savings now add up to several thousand yuan.

However, if you use money to buy food stamps on a large scale, it will definitely attract other people's attention.

Li Aiguo has been in and out of the weather station many times, and he knows better than anyone that if you buy dozens of kilograms of food at the pigeon market, no one will pay attention to you.

If you buy or sell thousands of kilograms of grain at one time, someone will come to talk to you before you even leave the pigeon market.

That group of people, led by Long Aotian from QQ Farm, would sell tens of thousands of tons of grain to the pigeon market at any time. Did they really intend to feed the entire capital city on their own?
Chen Xueru squatted on the ground with her butt sticking up, watching the rough man counting on his fingers and talking nonsense. Instead of feeling annoyed, her heart was filled with a sense of security.

Li Aiguo was planning how to store food, and before he knew it, it was the end of the month.

When he was driving back that day, he received a call from the weather station, saying that the military factory had delivered the special explosives to the weather station.

Li Aiguo hadn't seen Zhao Laoshuan for exactly seven or eight days. He rode his bicycle to the tavern at Zhengyangmen, bought a pot of old wine from Xu Huizhen, hung the pot on the handlebars of his bicycle, and staggered to the weather station.

The comrade in charge of delivering the explosives came from Factory 5411. Li Aiguo knew the chief engineer of Factory 5411, Wang Xianke, and had gone to Factory 5411 several times to deal with the rocket launcher issue.

In order to avoid leaks, Li Aiguo did not show up in person, but Captain Dong was responsible for conveying the message.

This type of explosive is a mixed explosive with all-nitrogen anion salt added to it. It is extremely powerful and its energy density is several times that of traditional TNT explosives.

Li Aiguo looked at the black thing and rubbed his hands excitedly. This thing was much more powerful than the pentaerythritol tetranitrate that Mossad used to tamper with pagers.

Such a big piece is enough to turn the bunker upside down.

The problem now is the delayed detonator.

"Considering that the target is a bunker, there is no way to use radio detonation, so we use the method of electric current heating detonation. Specifically, once the detonator is powered on, after seven days, the internal resistor will melt, thereby detonating the explosives."

The explosives expert sitting in the next room became nervous and explained the principle of the detonator in detail.

"Have you ever experimented?"

"We have conducted more than fifty experiments and the success rate is 100%."

"Thank you very much."

Hearing this, Captain Dong signaled that the explosives expert could leave.

The explosives expert wiped the nonexistent cold sweat from his forehead.

As an expert at Factory 5411, he had performed many confidential missions on a daily basis, but he had never encountered one with such a high level of confidentiality as this time.

In particular, he felt that the person in the next room seemed to be an expert, and every question he asked hit the nail on the head.

After the explosives expert left, Li Aiguo asked Captain Dong to bring the "special explosives" to the Institute of Computing Technology.

"Comrade driver, this thing won't explode, will it?" Captain Dong just heard the explosives expert say that just a tiny bit of this explosive is enough to blow off a person's legs and feet.

If such a large piece were to explode, the entire weather station would be destroyed.

"Don't worry. Without the detonator, it won't explode even if you throw it into the fire."

Li Aiguo was still admiring the explosives experts' brilliant ideas.

You should know that the special explosives are installed in the reading device of the vacuum tube computer, and the reading device must be powered when it is running.

In this way, the explosion time can be cleverly controlled.
