Doomsday: Unlimited upgrades to the shelter

Chapter 232 Blackbird High Altitude Reconnaissance Plane

Moreover, it is hidden during the day, and it is not afraid of other people's vandalism.

For foreign threats, Ma Wu intends to adopt infrared identification, which is not only effective during the day, but also plays a defensive role at night.

Once the infrared ray recognizes the threat, it will automatically load the shells and attack.

Because everything is set to fully automatic, even if no one takes care of it in the middle of the night, it will have no effect at all. For the protective shelter, attacking ordinary enemies is completely enough.

Six tanks are located around the shelter, and their range can basically cover the entire shelter without any blind spots.

As Ma Wu expected, the cannons on these tanks can only attack from a distance, and they will be fully attacked before the enemy approaches the shelter.

Xie Yannan knew that Ma Wu was very powerful in terms of attack power, but he didn't expect that the things he designed and transformed completely subverted his imagination.

"Then the six cannons are still movable, right?"

Xie Yannan remembered that Ma Wu had just said that the reason for upgrading the tall tanks in this way was to facilitate their movement.

In practice, however, they can indeed move rapidly.

The terrain around the shelter is very flat, no problem for their activities.

In this way, the coverage area of ​​the defense has become much larger.

After Ma Wu introduced this item, he picked up another blueprint on the ground.

The small characters on this drawing were densely packed, making it appear more complicated. Xie Yannan first took it and looked at it for a long time. Apart from the fact that the weapon on the drawing was an airplane, he couldn't understand any of the professional terms.

"You...are you remodeled with the planes here?"

Xie Yannan asked in a daze.

"Yeah, what he has here are all drones, that is, unmanned reconnaissance aircraft. There are the most common reconnaissance aircraft suitable for us in battle. As long as there is a battle, there must be this thing on the top of the head. "

Ma Wu paused and said, "Of course, it is mostly used for defense. The unmanned reconnaissance aircraft has a big flaw, that is, it does not hide. As long as the enemy is a little more careful, it is easy to find the enemy above the head." Abnormal. Instead, they do some fake moves to confuse the opponent."

"Yeah, I am very familiar with unmanned reconnaissance drones, which are similar to drone shooting."

In Xie Yannan's era, many parks had unmanned cameras above their heads, which were used to take pictures of scenery and the like.

"Then what improvements did Uncle Ma make?"

The tank just now has already made Xie Yannan feel amazing, this man is indeed a treasured man.

Ma Wu smiled, adjusted the glasses on the bridge of his nose, pointed at the drawing and said, "Don't look at it. You don't understand anything. I'll tell you directly."

The biggest flaw about reconnaissance aircraft is that it is easy to be exposed and easily counter-reconnaissance, so the best way is to make it highly camouflaged and invisible.

"It just so happened last time that our shelter wasn't detected by an invisible one? I analyzed the ingredients and produced exactly the same paint."

Taking advantage of the opportunity, he fumbled for a handful of paint in his pocket again.

Ma Wu continued to explain.

"I will make the appearance of the reconnaissance plane dark black. When it flies to a certain height and receives natural radiation and becomes stronger, it will automatically camouflage. Ordinary humans can't see anything flying on it when they look up. "

"Because high altitude makes it look much smaller to people on the ground, and after this appearance is processed, it receives radiation and appears the color of the sky."

"This makes it even more difficult to see. In addition, because flying at high altitudes quickly, friction with the air will generate heat, which can easily cause damage to the internal parts. I plan to add a layer of heat-emitting coating on the outside to make them withstand up to 540 In this way, even if you fly at ten times the normal speed, there will be no problem."

"Not only that, this heat-resistant paint was developed by me before. When the temperature reaches about 300 degrees, it will automatically cool down to avoid damage to the parts of the main machine."

Ma Wu smiled. The two biggest difficulties of unmanned reconnaissance drones were stealth and surveillance. He had already completely solved them.

"Of course, I checked, and their other parts are fine, and the intelligent monitoring can be used normally...but..."

Ma Wu said here, as if thinking of something, looked at Xie Yannan, "I need meteorites, the energy of these things can't be provided by ordinary people, only meteorites can provide them."

Xie Yannan happened to want to ask Ma Wu about the source of his power, but he happened to tell it himself.

"Then... how many meteorites do you need?"

After all, meteorites are limited, and there are too many weapons here.

"One piece of each weapon is enough. The energy of the meteorite is very powerful. When the weapon is scrapped, just take it off."

Ma Wu explained.

"That's okay. I'll bring them to you tomorrow. If you want to build these weapons... assign Shiliu and Xiaoxiao to you for use."

After all, these two people are not human beings, whether it is steel forging or installation, they are much better than ordinary people, and each of them is worth at least ten workers.

"Okay, it's just that there is no labor right now, so the transformation is a bit slow. If all the transformation is completed... it may take a week."

Ma Wu spoke in a daze, feeling that the delay was too long.

One week?
In Xie Yannan's opinion, it would take several months to complete these things.

"Your speed...shocks the heavens."

Xie Yannan swallowed silently, and began to admire Ma Wu from the bottom of his heart, at least he was a friend, not an enemy.

At least they are friends now.

If it were an enemy, this would at least be a boss-level enemy.

"The speed is fast because all the power sources are meteorites, which saves more than half of the process."

"Oh, by the way, there are two more things I have modified, let me show you."

Ma Wu's mental state is not very good, probably because he stayed up all night for research last night.

Even so, she was still explaining to Xie Yannan patiently.

"Is it the missiles and bullets?"

Xie Yannan remembered that the entire weapons base was just for raising things, and the two heaviest weapons had been perfectly designed and modified.But those two things have neither independent power sources nor large body sizes. How can they be transformed? !

Xie Yannan lowered his head on the ground to look for related blueprints, but he didn't see anything related to these two things.

"This……"

"They are relatively simple to transform. I have drawn the drawings in my brain, and there is no need to draw them."

Ma Wu yawned and pointed at the missile.

“Because its size is small, it just gives me room to modify it.”
