Chen Xin naturally knew nothing about Azu and others' intention to seize his refuge or even control himself. Chen Xin didn't even know that his refuge was being monitored.

But even if you know, in Chen Xin's opinion, this is not something worthy of his attention.

With the strength of the nickel-chrome armored steel door with a thickness of 300mm today, even modern troops must rely on heavy firepower to blow up the door.

This heavy firepower does not refer to heavy machine guns or rocket launchers, and even mortars are not enough. Instead, it is a real heavy firepower, at least the armor-piercing projectiles fired from the main battle tank.

Don’t think this is exaggerated. During World War II, the front armor thickness of the main turret of the Bismarck-class battleship was 360mm, the front armor thickness of the main turret of the USS Hood battleship cruiser was 381mm, and the front armor thickness of the main turret of the USS Missouri battleship was 495mm...

It can be said that Chen Xin's gate is the defense of the battleship class during World War II. During World War II, the main turret armor of the battleship was the thickest part of the entire warship. If you want to penetrate it, only the main guns of other battleships can be achieved.

Even with the advanced modern military technology, the armor-piercing ability of artillery has been greatly improved. If you want to penetrate 300mm of homogeneous nickel-chromium alloy armored steel, it is not something that ordinary caliber artillery can do.

Moreover, this kind of large-caliber heavy artillery is used to equip the equipment of the main combat troops of the front-line even in a military power such as the Blue Star Five. Not to mention the special police or armed police, even ordinary second-line troops may not have such heavy firepower.

So, several terrorists are really not taken seriously by Chen Xin.

Even if they could launch a human bomb attack and let the cannon fodder, who was not afraid of death, tied explosives to blow up the door, the two double-packed Maxim at Chen Xin's door were not for sight.

Although there are not many bullet preparations, there is no problem killing three or five hundred people with the assistance of automatic aiming.

To put it bluntly, with Chen Xin Sanctuary’s current defensive ability, even if the special police and armed police in the city attack together, there is no possibility of attacking.

The greatest victory they can achieve may be to use heavy machine guns to leave a few bullet marks on Chen Xin's shelter gate.

With such a defense, Chen Xin naturally would not worry about his own safety issues, and he also had time to transform his car.

After Li Yulong sent all the auto parts and other related materials, Chen Xin's car renovation plan was also carried out smoothly.

The car now is no longer the same as the SUV before, and it can even be said to be completely two cars.

If it weren't for the information state concept fuzzy technology provided by the system, no one would think that the car in front of him, which is comparable to a large bus was transformed from an SUV, and the two had no similarity at all.

Under the 12-meter-long body is a segmented track chassis, under the double-row three-proof cockpit on the front, there are four-meter-long tracks, and under the rear living cabin is a six-meter-long track.

Chen Xin originally planned to make a whole track, but after completing the upgrade, it became such a segmented style. He could only make a default decision. After all, he was not a professional, so he could not distinguish which one is better, a whole track or a two-section track.

The entire car uses 9mm thick steel plate as skin, and the main parts are equipped with armored protective plates? The chassis can withstand the attacks of mines or grenades? Even the glass in the front cockpit can only penetrate the large-caliber anti-equipment sniper rifle.

The surface is sprayed with snow camouflage? In this dark snow environment? This is the best camouflage. In addition, the triple 200KW isotope temperature difference battery with output power as a power source for electric drive promotion. This makes this car extremely difficult to detect.

The infrared night vision device included in the cockpit makes the car not even need to turn on the headlights when driving? It more effectively eliminates the possibility of the car being discovered.

In addition to these, the car also comes with a radar that Chen Xin doesn't know the model, which can easily detect all moving objects within a radius of 5 kilometers; and four military drones, two of which also come with machine guns as weapons.

There is also a hidden 12.7mm caliber three-pipe rotary machine gun on the roof. The high-explosion combustion armor-piercing bombs are equipped with cannot be driven by the main battle tank? There is no land vehicle that can withstand this level of firepower.

As for the interior of the car? The living cabin adopts a luxury RV configuration, equipped with a fully functional flow control desk, an induction cooker, microwave oven, sink, washing machine, dishwasher, and a cabinet that can store a large amount of kitchen utensils.

The dry and wet bathroom on the car is no different from an ordinary household bathroom.

The carefully designed two 2.1m×1.8m double beds and two 0.8m×1.8 single beds can sleep at least six adults without any pressure. Even if you squeeze, you will have no problem with me.

Is there a complete water circulation system in the car? It is equipped with a water tank that can accommodate five tons of water and a water treatment filtration system, which is enough to provide sufficient domestic water for six to eight passengers on the car.

Even in order to ensure that this car can meet the needs of long-term survival in the wild? Chen Xin also installed a five-layer planting box with 0.2m×0.6m on the car, which can provide sufficient vegetables? Paired with an oversized trunk at the rear of the car? It is equipped with enough food for six people to eat for a month without any pressure.

And with this car? Chen Xin has enough confidence to be able to return to his hometown and pick up his parents.

He believed that with this car, he could handle the journey of more than 600 kilometers across four provinces and successfully pick up his parents.

Of course, the cost of renovating such a luxuriously equipped and excellent armored RV is also extremely amazing.

If Chen Xin had not collected a large amount of raw materials through Li Yulong and transformed and processed a large number of parts by himself, the survival points required to upgrade such a car would be enough to upgrade a half-sanctuary as a whole.

Even with sufficient materials, the total survival point of 2,500 points still made Chen Xin feel extremely painful.

But he still gritted his teeth and devoted the survival point to it.

After all, this is to be used to pick up his parents' car. He is now afraid that there are any shortcomings or loopholes in the car that will not allow him to return to his hometown smoothly.

In addition, Chen Xin will be willing to do so no matter how much resources and survival points are consumed.

Now that such a car has finally been upgraded and renovated, Chen Xin also feels that it is worth the money.

"The transformation is finally completed! Ah Xin, your hands-on ability is really strong!" Ding Ning looked at the armored RV in front of him and was amazed.

In her and Qin Lan's eyes, this car was transformed bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit by bit.

However, in Chen Xin's opinion, this was a bit inconsistent, but in order to avoid revealing his biggest secret, Chen Xin still said to Ding Ning and Qin Lan: "Thank you for your help. If you don't have your help, I will only want to complete the transformation of this car, and I still don't know which year or month I will be busy with."

"Axin, you are polite. Aning and I didn't do anything. We just attacked you. It's nothing." Qin Lan shook her head. Although she and Ding Ning did help a lot from her perspective, her personality made her not feel that she had done much.

Chen Xin didn't care about this either. He opened the door on one side of the car body, lowered the gangway to board the car, and said to the two: "Two beauties, do you want to go up and take a look together?"

Faced with Chen Xin's invitation and the mighty, domineering, but restrained heavy armored RV in front of him, Qin Lan and Ding Ning looked at each other and couldn't help but smile. The two boarded the car together.

Because it was a car from the middle of the car body, after getting on the car, what appeared before the two of them was a table and a circle of shaped sofas surrounding the table.

Chen Xin also got into the car at this time and introduced to the two thoughtfully: "This is a living area, you can usually sit here for dinner or chatting. In front is the cab, behind is the bedroom, kitchen and bathroom."

While talking, Chen Xin lowered the table in the middle of the sofa and explained to the two of them with a smile: "This table can be lifted and lowered, and after it is lowered, it will be a double bed."

"Double bed?" Ding Ning looked at the table that had already fallen to the sofa next to him, and couldn't help but say to Chen Xin: "It looks quite spacious. Is it comfortable to sleep at night?"

"I don't know this, I have to sleep and try it." Chen Xin could only smile and say that he didn't know about this question.

Compared to Ding Ning, Qin Lan took the initiative to walk forward, walked through a passage less than half a meter long and entered the cab.

Chen Xin naturally followed, and saw Qin Lan looking at the various equipment around the driver's seat curiously, so he took the initiative to introduce it to her one by one.

Listening to Chen Xin introducing the radar, drone, night vision equipment equipped with this car, Qin Lan couldn't help but sigh: "A Xin, you are amazing. This is better than the armored vehicles used in our team."

"There's no way! After all, I have to travel through six provinces and run more than 600 kilometers to pick up my parents. If the car is not fully functional, I can't run such a long way before coming back." Chen Xin could only say that this is a practical need.

However, after hearing Chen Xin's words, Qin Lan just looked at him and asked him a question: "When are you going to leave and go back to your hometown to pick up your parents?"
