When the train stopped in front of everyone, the Iron Axe finally got a glimpse of it in its entirety.

It had only five sections, which was much shorter than the one on public display, but because of the steel plates that were wrapped around it, it looked much thicker and larger, and with its non-reflective pitch-black appearance, it resembled a prostrate wild beast.

The front and rear sections of the car are exactly the same shape, but they are arranged in a symmetrical arrangement - in addition to the two rotating machine gun towers, there are also many small holes in the armor belt below, which are undoubtedly used by the soldiers for observation and shooting.

The Iron Axe could already imagine what it would be like when the enemy rushed to the new weapon.

The spears that rained down hit the steel plates with a clanging sound, but the train did not move at all and kept moving at a steady pace. At the same time, more than a dozen flames erupted from the side of its body towards the enemy, turning targets into honeycombs that entered the range.

Whether it is a devil or an evil beast, they can only be beaten passively, and they can't do it at all. It was like a moving wall, providing the most reliable protection for the First Army wherever it went.

It's exciting just thinking about it!

There was already a faint discussion among the soldiers who were on guard around them.

But that's not the most eye-catching part of the train.

In addition to securing the front line for the First Army, its ultimate goal was to destroy the ruins of Tachira and the tower-tall skeletal monsters, so large-caliber artillery was a must.

At this moment, these two lethal weapons were placed on the second and fourth carriages.

Although it was still loaded with 152 mm fortress guns, according to His Majesty, these guns had longer barrels and more charges. The difference is evident with the eye alone - a single gun takes up almost all the space in the entire carriage, and not even a single machine gun can be stuffed.

The tail of the barrel was also surrounded by a large iron shell, which was even wider than the hull, so that even if the devil attacked from the air, it could not stop the artillery fire.

The only thing that worries Iron Axe is that this new surround design is extremely safe, but it also adds a lot of weight and volume, which is quite top-heavy. In particular, when the artillery is firing, it needs to be adjusted, and if the whole thing is rotated, will the train be able to withstand the violent impact when firing?

"Report to Your Majesty," a soldier trotted to the king and saluted, "all personnel are ready, please order!"

"This is a weapon that has not yet been officially installed, and whether it is repaired or improved, it is the responsibility of the engineering department. Roland smiled and shook his head, "So it's not me who is in charge of testing today, it's the head of the engineering department - you should report to her." ”

It was only then that Iron Axe noticed that the queen was also present at the test, but compared to the other witches, her outfit was completely in the form of overalls, so that he did not recognize it at first.

"Your Highness, Your Highness, Queen......" The soldier stammered a little, and he saluted Anna again, "All personnel are ready to ......"

"I see," Anna replied calmly, "let them start testing." ”

"Yes!" the reporter hurriedly shouted at the train, "activate the artillery!"

The vignette gave everyone a smile of understanding, but it didn't affect the test in any way, and the siren echoed over the forest as the command was given.

"Woo—————— woo ——————"

The iron axe immediately returned his gaze to the train, and when there was a crunch of a winch, he was surprised to find that the body of the car had changed.

Under the second and fourth carriages were two stout "iron legs", which he had thought were just inconsequential baffles. It wasn't until it was fully open that the Iron Axe realized that it was a machine that could operate on its own, with a flat iron plate fixed to the end of the "Iron Foot", which even held the carriage slightly up after falling into the snow, like the long legs of a giant spider.

This...... Isn't that what the devil's deformed species look like!

Could it be that His Majesty took this inspiration from his enemies and used it in new weapons?

But no matter what, the pure metal combination not only does not have a hint of evil, but is full of majestic momentum. When the iron feet were completely settled, the cannon finally pointed to the sky and let out the first roar!

In the violent tremors and air currents, the black behemoth did not move, as if it was consolidated with the earth.

......

It looked like it was working well, and Roland took off the earbuds and nodded approvingly at Anna.

These subsystems have been tested many times before they are loaded, and this time it is only to verify the performance of the integrated system, so it is not surprising that the first firing was successful.

In fact, he valued the four support legs under the gun mount more than the fire unit and power unit of the armored train.

This is the first practical test of a hydraulic unit.

According to Pascal's principle, the pressure on a closed liquid is equal everywhere in all directions, so in a U-shaped tube with unequal cross-sectional area, only a small section needs to be squeezed with less force to transfer a much larger force to the larger cross-section. It is precisely because of this amplification effect that hydraulic devices are used in a wide range of applications, from manual pressure jacks to pumping control machine tools.

Its only difficulty lies in processing and sealing, but for the current Neverwinter, there are no technical difficulties.

The train is equipped with a set of hydraulic support equipment controlled by electric motors.

Two steam-powered locomotives push and pull to drive the body, with plenty of power to allow the armoured train to travel at speeds of more than forty kilometers per hour, followed by two shelling units with fifteen rounds of ammunition in the turrets. In the middle is the ammunition loading vehicle, which is also the power source of the whole vehicle - one Shuguang No. 1 can meet the needs of two hydraulic pumps and interior lighting and ventilation.

These five carriages constitute the most basic unit of armored trains.

If speed of reinforcement is not a pursuit, new envelopes can be added to the front and rear of the vehicle, such as a personnel carrier or a sentry vehicle with more suppressive firepower. And this is also the charm of armored trains, by replacing the trailer knots, it is possible to combine tactical weapons with various uses.

Amid the endless exclamations of the crowd, Edith walked over to him with a smile.

"In this way, the most important part of the plan to attack Taqira has been filled," she said, stroking her chest, "I don't know the name of this new weapon?"

Roland pondered for a moment, "Let's call it the Black River." ”

"Black River?" Edith rolled her eyes, "Corresponding to the devil's bloodline?"

Worthy of the Northland Pearl, he couldn't help but raise the corners of his mouth, "...... That's right. ”

In areas that the red mist could not cover, the Devil had carried out thousands of criss-crossing red mist blood lines to maintain the needs of the frontline outposts, which were not only their lifelines, but also the bloody lines that the Federation feared. And now, there will be another color of lifeline on the fertile plains.

Darkened armored trains will carry men and ammunition and cruise through the desert plains, forming a new black river.
