Granite is a type of igneous rock, formed by the gradual cooling and condensation of magma in the depths of the earth's crust, as well as granitic metamorphic rocks, etc., the main components are quartz, feldspar and mica, with beautiful markings.

The wear resistance is 510 times higher than that of cast iron, the coefficient of thermal expansion is small, similar to that of iron-nickel alloy, the internal damping coefficient is 15 times larger than that of steel, the chemical properties are stable, not easy to weather, can resist the erosion of acid, alkali and corrosive gases, has non-conductive, non-magnetic, stable field, is a natural building material with excellent properties, and the surface weathering service life can be maintained for more than two hundred years.

The interior of the mountain, which is made up of this rock mass, has been hollowed out to create a huge space, and the internal structure has been reconstructed with super-strong concrete and steel bar, extending to a depth of 200 meters.

The thinnest part of the rock layer is at least 100 meters or more, and even if you use the most advanced GBU57A/B giant ground-penetrating bomb in service in the United States, you can only sigh with joy.

At most, a nuclear warhead can scrape off a layer of skin from the surface of the mountain, and even in the center of the nuclear explosion, the nuclear radiation released by the atomic bomb with the million-ton yield in service around the world may not be able to penetrate this thick granite layer.

Because of this natural characteristic, even the North American Air Defense Command of the United States is located under the tight protection of a 300-meter-thick granite formation.

Lin Mo and Mahia followed the "guide" Ye Yun through the heavy explosion-proof steel doors that resisted the shock wave of the nuclear explosion, and went deep into the ground to the inside of this heavily guarded underground facility.

The vastness and mystery inside this extinct volcano are far beyond the imagination of Lin Mo and Blonde Technology Lori, and even the base of the country's final strategic defense system where the "Dark Night" special service team is located is far inferior.

I never even thought that in this dark core world, there is a self-contained ** ecological circulation system, even if it goes deeper, the air is still fresh.

As a result of this trip, what they can see is only the tip of the iceberg.

After passing through the outermost entrance, facing the labyrinthine passage fork, the three need to sit in an unmanned open scooter and follow the automatic illuminated arrow indicators at the top of the passage and on the two walls in front of them.

The digital map management system that monitors the underground world automatically locks in the coordinates of the three people. Navigate the neighborhood according to the predetermined program, if it is an intruder, it is easy to get lost in this maze without a guide, and the invasion will become a nightmare.

"Arrived"

Ye Yun saw that the indicator light in front of him no longer appeared as an arrow, but turned into a standing human figure.

The scooter also stopped, and the wall of the passage on the left quietly moved away, revealing a large gate, revealing a space of about 10,000 square meters.

"It's so big."

Blonde tech Lori curiously looked into the door.

It's like a space the size of a football field. Surrounded by snow-white walls, with no pillars in sight, the space is about six stories high, and the micro-arched dome is illuminated and soft. It's like the sun at eight o'clock in the morning.

Dozens of soldiers with thick and long guns, wearing "Dragon Guard" tactical armor and three "Jairus 3" light mobile armor are standing on the inside of the gate with live ammunition standing in a small line of firepower point formation, which can splash a dense focus of fire at any time, but the object of defense is not outside the gate, but the space inside the gate.

These warriors only have the number and rank identification on the heart of their chests, and their whole people are shrouded in "dragon guards", and they can't even see their appearances.

An indescribable terrifying beast roar came from the space inside the door, making people palpitate.

"'Dragon Knight', the test site is here."

Ye Yun was the first to get out of the car. Make a gesture to come in.

This is a voluntary test project.

To her surprise, Lin Mo actually refused the invitation of the "relevant departments" to him.

It is really unexpected that higher ranks, more generous treatment, and more exciting advanced combat weapons will not make the other side tempted.

Although he rejected the olive branch solicited by the "relevant departments", Lin Mo did not refuse to earn some extra money to subsidize the "family", and the labor fee given by the other party was quite considerable, although the final result was not the same as originally imagined, but everyone was happy.

Since leaving the aviation school and joining the 7759 Brigade, Lin Mo has started to make soy sauce all over the world as a "part-time" business. This has long been commonplace. Commonplace.

At the speed of the X8 "Demon" Shape-Wing Fighter, the combat radius of the Dragon Knight can cover almost the entire region of Asia and the Middle East.

If there is another stargate or something. It's still the same beating.

This secret test is an actual combat evaluation of Lin Mo, which will be related to the "relevant departments" deciding which level of combat power like Lin Mo can be put into battle.

After all, the Dragon Knight is not a nuclear warhead, and there is a limit to being alone.

"'Dragon Knight', these are weapon racks, there are individual weapons of various sizes, you can choose at will."

A warrior wearing a "dragon guard" with a tactical helmet covering his face greeted Lin Mo in a deep manly voice, prompting him to the six sets of tall shelves at the entrance of the gate.

At intervals of two meters, there are six groups of shelves lined up on the left and right sides of the gate, and a variety of individual weapons are placed in different categories.

Long guns and short cannons, all kinds of cold weapons, all kinds of weapons, even Lin Mo's "Dragon General" tactical armor is also placed.

Due to the security system, Lin Mo and Mahia came here to enter unarmed, and the "Dragon General" dual-purpose tactical armor was also brought in in advance and placed here for Lin Momo to temporarily wear on the test ground.

Next to the "Dragon General" is a new set of pure land combat type defense enhancement "Dragon Guard", which adds an extra free choice.

Because the army receives much less information in battle than the pilots, the "Dragon Guard" is much inferior to the advanced version of the "Dragon General" in terms of overall control and various support functions.

At the end of the shelf, there was also an empty "Jairus 3", which opened its cockpit and parked there.

Compared to flying a fighter jet, the maneuverable armor, which has been carefully designed over a long period of time and simplified to operate, is much easier to control.

The shelf was a small arsenal, and the bullets were placed on several large long tables between the shelves, which could be accessed at will.

"87756, bring Longinus here"

Ye Yun glanced at a "Dragon Guard" soldier beside him.

"Yes"

The "Dragon Guard" warrior, with the number "87756" clearly marked on his chest, greeted the others, and four long, heavy metal boxes were lifted over and leaned against the large long table where ammunition was kept.

"Longinus?"

Lin Mo was stunned, he even provided this?

The fighters entered the code on the box in turn, and then each used two keys of different colors to unlock the lock synchronously to the sound of the "three-two-one" slogan, revealing the contents of the custom groove inside the box.

One by one, the familiar spears entered Lin Mo's sight, three strange spear bodies twisted into one strand, exactly the same, five in a long box, and an empty groove in the last box.

Counting them down, nineteen Longinus spears were placed in front of everyone like they were printed in a mold.

The Spear of Longinus Kicks Down?

Lin Mo casually picked up one and checked it in his hand, and the weight was exactly the same.

The light battle qi quietly poured in, and a sense of superconducting fluency without any loss was spontaneously generated, and the light battle qi almost effortlessly penetrated all the way to the tip of the spear, making the entire spear like Lin Mo's arm.

There is no need for those destructive identifications, and light warfare gas is also a very reliable identification method.

It is genuine

Picking up another one, the dragon knight was finally moved, it was still really two genuine Longinus, this was not a dream.

It's still true to go on

Everyone just watched as Lin Mo took the Longinus guns in his hands, checked them, and put them back in the box.

"It's all true?"

Lin Mo looked at Ye Yun with surprise.

If these things were sold, the money would probably be enough to build a small country.

"Can you tell?"

Ye Yunyong nodded, a little curious.

These are the spears of Longinus, which have been accumulated by Chinese civilization over thousands of years, and all the spears of Longinus in the hands of the Chinese government are here.

The handwriting of the "relevant departments" is really surprising, suspicious people are not used, and there is no doubt about employing people, but this time the combat effectiveness evaluation test actually took out all his Longinus guns at the bottom of the box and let Lin Mo use them.

Put the test site in the base inside this granite mountain, and only in this place where even the virus can't escape, the "relevant departments" will put out all the Longinus guns at the same time to ensure that there will be no accidents, even if Longinus is sharp, it is impossible to turn into pangolins and excavators to escape.

It's no wonder that someone dared to intercept Lin Mo in the middle of the road, but they didn't dare to go to the 099 Research Institute to spread the wilderness, just by entering the gate and letting a heavily armed army attack, I am afraid it would be impossible to break through the first line of defense outside.

"Yes" Lin Mo took a deep breath and nodded, "Feel"

"So that's the case" Ye Yun smiled and said to Lin Mo: "You can use these, one, two, even if it is used as a throwing gun, but you have to complete some default items first."

The hand feel identification method is a special ability that only the most experienced professionals will have, just like the eighth-level fitter, which can reach the fineness of high-precision machine tools by feel, and even the first generation of modern machine tools are all handmade.

"I don't need it"

Lin Mo finally shook his head and put down the Longinus Spear in his hand.

The one that belongs to you is among them, and each Longinus spear is glued with a very strong sticker with brief information such as the time of acquisition, the name of the battle, and the exclusive number.

But now the Lance of Longinus doesn't make sense to him.

For the dragon knight, this is just a small experiment, there is no need to slaughter chickens with knives.
