Three Kingdoms, at the beginning of the game, recognize the thief as the father, hit the spectacle,

……

"put!"

……

The voice of the host continued to echo in the school field. Since the thunderbolt car was different from other weapons tested before, it needed to be calibrated several times, so this test was more time-consuming and laborious than the previous tests combined.

But fortunately, all the people present are veterans who have been fighting for a long time, so the use of the thunderbolt car is not difficult for them.

After repeated proofreading, soon the first boulder drew a graceful arc in the air, and bombarded the cement concrete fortification in the distance at an angle of 45 degrees obliquely upward.

Chapter 49 Finale

"boom--"

The huge boulder crossed a distance of more than [-] meters and hit the concrete fortification directly.The smoke and dust brought by the collision between the stone body and the wall quickly covered the area, and everyone present stretched their necks and looked forward to it, hoping to take a look at this once the strongest firepower projection device. Whether it can hurt the cement fortifications.

Unlike the previous small fights, this time, the loud sound of the boulder falling made the legs and feet of everyone present a little weak, and even many people on the front line subconsciously took two steps back.

After all, human beings are also creatures, and creatures seek advantages and avoid disadvantages after all. Faced with an attack that can undoubtedly kill them quickly, the first reaction of most people must be to retreat silently.

This time, though, curiosity finally got the upper hand.

Those soldiers were silently watching the scene in the smoke and dust. When the smoke and dust were finally blown away by the wind, the status quo of the bombardment reappeared in front of everyone.

Not moving.

When the smoke and dust dissipated, what appeared in front of everyone was an intact cement fortification. From the outside, except for a little floating dust, everyone couldn't even see the difference between this fortification and the previous bombardment.

It's as if the boulder just now didn't exist.

Not far in front of the fortification, a huge boulder was lying there, looking innocently at the people present.

"So... so unscathed?"

"Could it be that it missed just now?"

……

"No... no, just now the stone clearly hit the wall, and even the hammer with both hands can knock a hole in the concrete wall. How could the thunderbolt car fall down so far away, how could it be unscathed? ?”

……

Slight commotion echoed in the crowd, and many soldiers looked at the motionless wall not far away with some surprise, not only a little surprise in their eyes, but even a trace of fear.

Even Zhang Yan was sitting high on the stands, he couldn't help pulling his neck to watch the distant scene.

Fortunately, in the end, before the panic formed, a sharp-eyed soldier seemed to have discovered something, and immediately shouted loudly.

"and many more!"

"This wall is not unscathed, the place where it was hit just now has already cracked!"

"Look, the crack is still spreading dust down, but because the crack is so small, it's hard to find it directly when we look at it."

"Quickly, go and report to the prefects. If this concrete wall is attacked head-on, it will still shatter. It is not always unscathed."

……

The messenger quickly passed the front-end news to everyone on the high platform, and after learning about the current situation, the experiment continued.

Since the strength of cement largely comes from the unity of the overall crystallization and the integrity of the structure, when the stone wall is smashed into a crack, even if the crack is small, the strength of the wall itself will suddenly drop down.

As Zhang Yan expected, after the next few stone throws hit the cement concrete fortifications, especially after a stone bullet hit the previous crack directly, the originally invulnerable fortifications finally shattered, and the two-meter-thick stone wall just like this It turned into a large amount of debris and collapsed directly.

Fortunately, this level of collapse will only affect the soldiers fighting directly above the fortifications, but it will not collapse backwards, let alone directly harm those working in the area behind the fortifications.

Subconsciously wiped the fine sweat off his face, after the fortifications used for the test were broken, all the soldiers present let out a long breath, as if they had finally relaxed.

Until then, the few people who were in charge of actually operating the equipment found that their hands and feet had become cold and shivering, and they didn't know whether they were nervous or scared.

It has to be said that if weapons of the level of Thunderbolt cannot break through the defense, then one can imagine with the back of your head that this kind of small and medium-sized wartime fortifications that can be quickly built anytime and anywhere will be of great value to those troops without large firepower. What a tough bone to crack.

But now that the experimental results of the thunderbolt car have come out, it is time for them to express their emotions.

The sun is now a bit westward, and before the end of the day, they still have to test the experimental results of the King of War—that is, the current killer artillery of the Lujiang Bingma Division.

After witnessing the pinnacle of firepower in the old era, such as the thunderbolt car, many people present became curious about the Type [-] artillery type [-] that Lujiang had just put into production.

……

"All! Ready for the last test!"

"The gunner began to calibrate the shooting parameters, and the rest of the soldiers immediately prepared their ammunition!"

……

Following the orders from the upper echelon, the original school grounds began to turn around, and became busy again.

The red cloths on the cannon carriages were torn off, revealing the true face inside the red cloths to the outside world.

The last "big axis" to appear is naturally the Type [-] artillery.

Compared with the trial-produced Type 1.1 artillery made before, the barrel length of the Type [-] artillery is slightly inferior to that of the opponent. The effective length of the barrel part is only about [-] meters [-], which is about [-] times the diameter.

The reduction of the multiple diameter is naturally a decrease in the overall power of the artillery.

According to the previous trial version, the effective range of the Type 200 artillery with 500 times the diameter can reach more than [-] meters, and the maximum range can even throw a [-]mm projectile over a distance of more than [-] meters.

"Qian xun" ②0㈥㈧3

As for this mass-produced model, or the shrunken version, the shooting range has been cut to a little over 200 meters by Ma Jun's superb "knife technique".

But then again, since it is said that it is a compromise made for mass production, it is not without benefit to reduce the diameter of this batch of artillery.

Judging from the overall weight of the cannon, the current cannon of the opposite sex weighs just a little over 600 kilograms, which is lighter than the previous behemoth of more than [-] kilograms by the weight of two adults.

Don't underestimate the difference in weight between these two hundred catties. You must know that in many cases, this weight is a little bit lighter, which can save a lot of cost for Lujiang Bingma Division during long-distance treks or military transportation.

Furthermore, the entire body of the cannon is made of brass, which increases the weight by two hundred catties, and saves two hundred catties of copper.

The current type 16 artillery only consumes a little over 20 brass for forging, which is a lot less than the [-] budget estimated by Ma Jun before.

Now that the output of brass is gradually increasing, I believe that in the near future, the wealth that Zhang Yan needs to pay for the production of artillery will only be the wages of the workers.

Chapter 50 Consecutive Products

Not much to say, when the red cloth was uncovered, what caught everyone's eyes was a row of five very delicate cannon carriages.

These sports cars are all driven by two wheels. The main body of the artillery mounted on it is at least 1.3 meters long, and the barrel accounts for about [-]% of it.

Behind the barrel is a specially thickened chamber and a gun port specially used to ignite the primer.Although it looks simple in structure, under the meticulous workmanship, it reveals a touch of delicacy and high-level sense.

Especially on the side of the gun body, the golden brass was fixed with a gun hoop to prevent the chamber from blowing up, and the gun hoop was printed with a series of delicate small characters:

……

"Model: Type [-] Artillery Type [-]"

"Production batch: Zhongping No. [-]"

"Time to become a cannonball: the winter month of the fifth year of Zhongping"

"Supervisor: Ma Jun"

"Delivery object: Xu Huang Gongming, the marching governor of Lujiang No. [-] Army and Horse Command Division"

……

I saw that the cannon is clearly engraved with information such as the model, production batch and completion time of this cannon, such as the production batch, "Zhongping" refers to the year name Zhongping; the first "zero five" It refers to the fifth year of Zhongping; the second "zero one" refers to the first mass production in the fifth year of Zhongping; and the last "[-]" represents the number of this gun, meaning It was this cannon that was the third qualified finished product produced in the entire batch.

If the production quality is not up to standard, they will be returned to the furnace and remade, no matter how bad it is, the production batch number will not be printed, and it will be leaked outside to harm others.

As for the supervisor and delivery target, it is a detailed record of who hand cast this batch of artillery, and where it flowed into, so that the whereabouts of each artillery can be traced, thoroughly Cut off the possibility of reselling and selling arms privately.

It has to be said that after polishing the cannon body as a whole, these cannons were lined up in front of everyone, and the golden appearance was really quite powerful.

In particular, five numbers from one to five are clearly engraved on the side of the cannon, which is like the serial number equipment of later generations, which can increase the actual combat capability of these cannons from a metaphysical point of view.

In fact, it's not that these cannons happen to be serial cannons, which can satisfy Zhang Yan's obsessive-compulsive disorder...

It's just that these artillery are already all the stocks that Lujiang currently has.

From last fall to the present, in the six months' time, there were only five artillery pieces that had been confirmed to be completed and passed the quality test.

If you want to wait until all fifty artillery pieces are ready at this rate, it will take at least three years before the Huainan Industrial Zone is completed.

three years?How many three years can there be in life?

Thinking of this, Zhang Yan couldn't help sighing—he definitely couldn't wait for three years, and even this year, at some point, Liu Hong would return to the west completely, forcing him into a relationship with that northern border overlord. Inside the quagmire of war.

As for how much the production capacity of Lahip can be increased with the help of Huainan Industrial Zone, it depends on his luck.

……

"First calibration shot—"

"preparation!"

……

The high-pitched voice woke Zhang Yan up and brought him back from his thoughts.

Now that the cannon has been cast, it must be used after all, not viewed.If you want to know the actual effect of this thing, you still have to use it.

Zhang Yan refocused his attention on the school field, where the order for the first calibration shooting had been issued, and the soldiers operating the artillery were methodically pressing the primer into the barrel, putting in the shells, and manipulating the artillery carriage to shoot the cannon. The mouth was probably facing the direction he needed to aim at.

When the entire school ground became quiet, the host gave an order, and a familiar rumbling sound rang in Zhang Yan's ears again.

……

"fire--!"

……

This time, the sound of the artillery was no longer just a single click like in the previous test, but it rang out continuously.

……

"Boom-"

Accompanied by the ear-piercing sound of explosions, the row of cannons in front of Zhang Yan burst into intense flames, and then the five projectiles were suddenly sent out of the muzzle by the expanding air, turning into a black afterimage, heading towards The intact part of the distant fortifications shot past.

Although he had seen cannons firing once in the Eastern Han Dynasty, the sight of five cannons firing at the same time made Zhang Yan's heart tense subconsciously, and he clenched his fists much stronger than usual.
