Hu Fei put forward the design plan, and a group of skilled craftsmen worked for three days, and the first movable fortress with practical significance finally debuted.

The new generation of movable fortresses has been revolutionized on the basis of the original iron table. The original flat table top was transformed into a semicircular vault, and two of the four table legs were added to make six legs, with an additional bulletproof steel plate between the two adjacent legs. The supporting legs were shortened, and larger and more durable steel wheels were added under each leg. The outside is painted with a layer of grass green paint, not to mention how spirited it looks.

Drag the active fortress to the range. Like last time, first with a rifle, then with a machine gun, and finally with a mortar. Bullets and shells were hailed one after another on the movable fortress, and the circular vault above made the sparks rattle. In the end, when the mortar was test-fired, Hu Fei took a telescope and stared at the active fortress.

The trajectory of the cannonballs was invisible, but Hu Fei saw that a ball of fireball seemed to be crooked before exploding after hitting the dome of the active fortress. The same goes for the next shell. When the explosion was over, Hu Fei and a group of experts and craftsmen rushed over to take a look.

The poor goat tied under the table saw that someone was coming, and quickly raised his neck and called for help: "Baa-" It didn't know that it was the vicious human beings in front of him who caused it to suffer so much!

The goat didn't die? The experts, craftsmen, and leading cadres like Hu Fei who heard the sheep's cry were stunned for a moment, and then immediately let out a thunderous cheer. It worked! We've finally made it!

A new type of armor activity fortress has been successfully developed! Hu Fei immediately ordered someone to report to the commander of the theater of operations, and asked the commander of the guard to personally test the actual combat performance of the active fortress!

As soon as Wei Lihuang heard that Hu Fei's armor research had made a breakthrough, he put down everything at hand and came with a group of adjutants and staff officers. The advent of new armor is a big event, how can Wei Lihuang, who has always been famous for loving soldiers like sons, not be anxious.

"All over the world, something has been developed? Where? As soon as they met, there was no regular greeting, Wei Lihuang directly inquired about the new armor developed by Hu Fei.

"Sir, look!" Hu Fei's body flashed to the side, and the four technicians lifted the cover to reveal the strangely shaped activity fortress below.

Wei Lihuang circled around the activity fortress three times in a row, and couldn't stop exclaiming, "Great! With this thing, how many fewer warriors can we die? This looks like a small chariot! This thing is called an activity fortress? Well, the name is good, this is a fortress, a fortress of activity! Still wheels underneath? So that the soldiers at the front can push away, okay! Well done all day! ”

In the face of Chief Wei's unstoppable praise, Hu Fei was humble and ordered the personnel of the R&D department to prepare for the test launch.

Speaking of which, we have to explain a little: Hu Fei's infantry armor research and development department has a director, but this director is concurrently held by a deputy director of the theater logistics department.

The deputy minister is still too busy with a lot of things, and he simply doesn't have the time to take care of this armor research and development department that has no oil and water at all. Except for the first day when Hu Fei took office, the vice minister showed up, and the rest of the time was simply the beginning and the end of the dragon. In other words, Hu Fei is the actual person in charge of this infantry armor research and development department!

Test firing began. Rifle-machine gun firing was followed by a grenadier shot, followed by a mortar. Bullets and shells were fired continuously, and explosions followed one another. Half an hour later, the situation finally calmed down, and Hu Fei accompanied the chief over to check the defense of the active fortress.

The sheep was still crying loudly; The camouflage paint painted on the movable fortress is speckled and completely out of shape; The six legs and six wheels below were still intact, and the experiment was a complete success!

Chief Wei praised a lot of words, and finally put it forward: When will it be able to conduct a real combat demonstration?

Live demo? Hu Fei hesitated slightly, and the welding expert standing next to him interjected coldly: "The live demonstration can be done at any time, that goat is fine, and it will definitely be fine if you change to an adult." "This welding expert is a professional welder who came back from the United States, and he will say whatever comes to mind, and he has never had any scruples.

"Oh? Is it true that you can do a live demo at any time? That's great, it's worth it today! ”

Chief Wei clapped his hands and smiled, but Hu Fei was worried. He can't blame other welding experts for talking too much. These experts have a big temper, and if he says a few more words, it will be boring for the two of them to argue in front of the Wei Chief and make everyone unhappy.

Isn't it just a real person, it's on it, and I won't be able to run this time sooner or later anyway. Picked four volunteers and stuffed cotton in everyone's ears, and the real person started!

Rifles, machine guns, grenadiers, mortars, take turns firing. From the beginning, Hu Fei's heart hung in his throat. It's not just him, but Wei Lihuang is all stern with a face. After all, no one wants this kind of real thing to happen to the living, and no one wants it to fail.

After the test firing, the smoke gradually dissipated, and there was still no movement at all in the active fortress. Hu Fei suppressed the tension in his heart, stood up and invited Chief Wei to watch together. A large group of staff officers, adjutants, and experts from the Armor Research and Development Department accompanied Chief Wei towards the shooting range, and Hu Fei walked in the front.

Seeing from a distance that the active fortress seemed to be no different from before, the tension in Hu Fei's heart did not decrease at all. When they got closer, the four people under the activity fortress could also see clearly, and the welding experts and blacksmiths from the R&D department were the first to resist it, and rushed out of the crowd and ran over first.

"Hey, how are you doing?" The welding expert shouted as he hurried to the front and bent down to pull the man out from under the movable fortress.

One, two, three, four, and the other four were all standing there alive, and the test site suddenly erupted in an earth-shattering cheer, "It's a success!" We did it! ”

Hu Fei asked the four warriors with a smile on his face, "Are you all right?" How does it feel? ”

"Report sir, we're not hurt!" The four of them reported their physical condition in unison, causing the chief of the guard present to laugh loudly.

"Okay, tell me how you feel?" Hu Feile asked hehehe, seeing that the four people didn't react, his smile froze, could it be that people were deafened by the explosion?

The assistant quickly ran over and gestured to the four people. The four warriors like the Black Iron Tower smiled and took out a lump of cotton from each ear, it turned out that their ears had just been blocked!
