Wang Wuyun took a few serious glances at the shelter buried in the big pit, and shook hands with Dai Qiang, "Mr. Dai has worked hard, and he got ......it done so quickly."

"Hahaha, it's not hard, it's not hard, the sooner this thing is, the better, my people are doing this, and now everyone is very happy when they hear that there is work to do and wages to be paid, and now the people in the factory are back and are preparing to do a big ......job," Dai Yande said in high spirits.

"Yuexin, how do you feel after watching it?"

"If I can't install it at home, I want to install one, this thing is too secure!" Zhu Yuexin, who had just visited the safe house, replied with some excitement, "By the way, Wuyun, I can't believe that this thing was designed by you, you will have a lot!"

"It's nothing, it's not much advanced, as long as you pay attention, you can naturally make it!"

"You didn't learn it online again, did you?"

"This thing is also available on the Internet......

Hearing Wang Wuyun say this again, Zhu Yuexin was speechless, he couldn't find how to refute it, every time Wang Wuyun said this, he felt wrong, but he couldn't find any logical loopholes, in Wang Wuyin's mouth, the word "online" seemed to have become his personal universal tutor, and he could learn anything from the Internet.

Dai Yande smiled and looked at Wang Wuyun and Zhu Yuexin talking, he really couldn't see through Wang Wuyin, but for Zhu Yuexin, he found out Zhu Yuexin's character after an hour of contact, Zhu Yuexin said seriously, in Dai Yande's eyes, he was a simple teenager who didn't know anything about the world, no protruding specialties, no protruding abilities, and no prominent family background and relationships that could be used.

Dai Yande didn't know why Wang Wuyun was so good to his high school classmate, and it was already a little too good, the dividend right of seven percent of the shares of the iron house company, Wang Wuyun actually gave it away with a word, and gave it to his classmates and friends, tens of millions of investments, here in Wang Wuyun, just like a child playing at home, Wang Wuyun doesn't seem to pay much attention to this money at all.

Two days ago, when Wang Wuyun came to the factory to guide the workers' technology, Dai Yande asked curiously and vaguely why Wang Wuyun was so good to Zhu Yuexin.

Wang Wuyun's answer to Dai Yande made Dai Yande still fresh in his memory.

Wang Wuyun said to Dai Yande, "If you really regard a person as a friend, then what does he do, what ability he has, and it doesn't matter to you how high or low his status is, but it is very important to you to see him doing well!"

It was Wang Wuyun's words that touched Dai Yande, who had been rolling in the rivers and lakes for many years, in his heart.

At the beginning, Dai Yande looked down on Zhu Yuexin, but after Wang Wuyun's words, Dai Yande began to envy Zhu Yuexin.

Dai Yande also wants to have such a friend.

Seeing Wang Wuyun and Zhu Yuexin talking, Dai Yande said beside him, "Mr. Wang, let's go down and take a look, this is the No. 1 refuge of our factory, and we have to wait for your acceptance!"

Wang Wuyun smiled, "Let's go, Mr. Dai, let's go down and have a look......"

"Okay, okay, let's go down and have ......a look together," Dai Yande said, and took Wang Wuyun to the edge of the big pit, and then went down directly to the bottom of the big pit from the repaired steps, because the entrance to the safe house was below.

The pit has been hardened with cement, and there is a railing around the pit to prevent people from falling, and the top of the pit has a fiberglass shelter to protect it from rain.

Around the huge metal can, according to Wang Wuyun's request, the layer of reinforced concrete poured around the metal tank after construction and the natural soil layer on top of the reinforced concrete were retained, and turned into a facet that could be displayed to everyone.

Looking down in the pit, it will give people the effect of watching biological slices, and you can see the underground structure design of this family shelter at a glance - a natural soil layer more than one meter thick, and below it is a one-meter-thick reinforced concrete pouring protective layer, and under this pouring protective layer, there is an all-steel steel shelter, such a warrior will bring a full sense of security to those who watch.

The ground above the Vault is also covered with flowers and plants, and there is a Vault's ventilation duct grille and an emergency entrance above the ground, both of which appear to be inconspicuous.

The three of them got into the shelter from the entrance of the shelter, and as soon as they entered the shelter, Wang Wuyun saw the ring support like the keel of the ship in the big iron can, and the vent of the shelter was in the middle of the shelter, and in addition to the entrance to the shelter, the shelter also had an emergency escape sign to the ground.

There are several LED lights in the shelter that are protected by iron shells, and the light of the LED lights illuminates everything in the shelter clearly.

The entire shelter, from the inside, looks like a cylindrical room, inside the vault, there are two high and low beds that can sleep four people, as well as a chemical toilet and a storage room.

On one of the walls, there are several rows of movable grooves, which can be used as storage space for the shelter, and at this moment, in the two of the grooves, there is a transparent device like a goldfish bowl, and the transparent device is full of pale green liquid, at first glance, it will make people think that there is a fish tank here, and the water in the fish tank has not changed for many years.

Dai Yande proudly patted the thick metal shell of the shelter, "Brother Wang, what do you think, this is all made according to your requirements, not to mention the structure of this shelter, it is the paint inside, my side is also in strict accordance with your requirements, Brother Wang, the use of methanol-free ecological and environmentally friendly paint, waterproof and rust-proof, after the completion of the harmless treatment, there is no smell!"

Wang Wuyun patted the steel support keel in the circle of the shelter with his hand, and nodded secretly, this is the structure on the submarine, this strength is definitely enough, by this standard, unless this shelter is directly hit by a ground-penetrating bomb, otherwise, even if it is directly hit by a 155 caliber heavy artillery or rocket, or the houses outside collapse, the people inside the shelter will be fine, as for the zombies or something, it is impossible to break through such a solid defense.

When such shelters are built, each shelter can allow one more family or several people to survive at a critical time.

Wang Wuyun checked all the things he asked for in the shelter one by one.

The shelter is equipped with a manual piston air pump, which can manually ventilate the shelter to avoid the entry of toxic and harmful gases and radioactive fumes from the outside.

There are two electric power supply systems in the shelter, one can be connected to the outside solar and small wind power units, or directly to the power supply of the villa, and the other is purely manual, like a spinning bike, which allows people to exercise and generate electricity by stepping on it.

There are also two sets of observation and monitoring systems in the shelter, one is to observe the outside environment through the camera placed in the outer ventilation grille and the display inside the shelter, and the other is a very primitive optical observation system, similar to the periscope in the old submarine.

Other features include four professional walkie-talkies, a battery pack, a manual pump, a radiation monitor, a shockwave monitor, several fire axes, a small air water generator and an algae incubator.

In the groove of the metal wall of the shelter, the goldfish bowl filled with half of the green liquid was the algae incubator that Wang Wuyin specially asked Dai Yande to configure in the shelter, and the liquid in it was indeed water, and the green in the water was the edible microalgae plants that grew in the water......
