"Grenades?haha......" Li Yunlong laughed so hard that his stomach hurt, "You can use this thing as you like, it's best to use it up!"

After Li Yunlong finished speaking, a piece of information was given on the TV, which was about this grenade.

At the beginning, in the face of the two opponents of the North Soviet Union and North America, there was a possibility of large-scale invasion by the other side of the army and the purge of the atomic bomb at any time, so various domestic industries were modularized and miniaturized at that time.

For example, in the Fourth Five-Year Plan of 1970, the central government demanded that "five small industries" be built in almost every locality: small coal mines, small iron and steel plants, small fertilizer factories, small cement factories, and small machinery factories.

In such a situation, the military industry also produced rifle ammunition in large quantities, and it is said that at that time, grenades were made according to the head, and one person could divide dozens of them.

There are countless such armaments, from the top "underground Great Wall" to bullets and grenades, which is really a national policy to carry out national resistance, and perhaps it is this determination to break the kettle, plus other reasons, that made those two superpowers press the invasion of their own land.

These produced bullets and grenades were later used up in various wars, but the number was so large that there was still a shelf life, so the army finally no longer lacked anything like the Korean War, as long as a soldier dared to practice guns, there were countless bullets to feed him, and the same is true for grenades, and it is said that these grenades are still in use in the army now.

"That group of old beauties laughed at us all day long and still used grenades, saying that we were backward, but we are a mountainous country, and we really want to fight, attacking in the mountains, and the round grenades won't blow us up ourselves?

Li Yunlong waved his hand, and the transformation of the two of them in one shot had already come to the troops.

……

Su Liu, who was in front of the TV, sat up all of a sudden, his eyes wide open, and he didn't blink.

I learned from my daughter that in the virtual world of the Korean War, although a few small pieces of temporary modern villages were designed due to the filming of "Bright Sword", such as the background environment of Zhao Gang and Li Yunlong's two homecoming plots, but it was only these small pieces, and other existences in reality were not simulated at all!

What's more, this is a force that can be called a state secret?!

This seems to be a shooting during a military exercise, which is markedly different from the previous season when the wheat was ripened at the farmhouse, and also confirms its authenticity.

Like Chu Yunfei, he was stunned by this real performance scene.

Boxes and boxes of bullets could no longer attract their attention, and what shocked him even more was the torrent of rolling armor, right on a plain, rushing like a pack of steel wolves!

Chu Yunfei and Li Yunlong were standing there, next to them, a tank battalion was passing by on both sides, and the fake target on the dirt slope in the distance was destroyed by a cannonball's accurate shelling, and Chu Yunfei's eyes lit up!

It's a tank!

Chu Yunfei, who was shocked by this tank battalion, had not yet calmed down. The rocket artillery unit has also started a new round of "floor washing"!

It seems that it was because it was bombarded by the Yingdao devils and the coalition devils at the beginning, and some "excellent viewing effects of covering the bombing", so that the rocket artillery became the permanent firepower of the troops, and the others were even made into "fire trucks" and sold to international friends for "peaceful purposes".

Dozens of rocket launchers on a rocket car, in just a moment, like a comet hitting the moon, suddenly attacked, on the target field, only to be bombed miserably, uninterrupted firepower covered, at least in terms of visual effects, than artillery bombardment looks more powerful!

Before Chu Yunfei could take a closer look at these rocket artillery, a sound of rapid flight had already sounded overhead, and a group of fighters were driving in the air with various tactical maneuvers of various schools, and they made a surprise attack on those targets that were still alive.

Under the joint fire of the three armies, in the midst of the rolling iron stream, Chu Yunfei stood in the middle, forcibly holding back the agitation in his heart: "This ...... It's all ...... Yours?"

Li Yunlong laughed: "This is all 'ours', the brothers are on the wall, the outside is insulted, the world is too peaceful, you, a real soldier, do you still think about the little at the beginning?"

was silent, Chu Yunfei didn't know what to say, but the next successive performances made him completely forget the awkwardness in his heart, and also made Su Liu in front of the TV look full of enthusiasm.

The Underground Great Wall!

The whole journey is 5000 kilometers!

The original construction of the underground Great Wall was to withstand the other side's nuclear attack, nuclear retaliation against the other side, and now because of their own strength, these underground passages have been opened to the public, and some have even formed tourist spots, attracting many Chinese and foreign tourists.

Highway, bridge, high-speed rail infrastructure projects!!

These most basic infrastructure, is the most intuitive embodiment of a country's strength, the huge high-speed rail network is covering the whole country step by step, the technology learned from foreign masters, has been out of the blue and better than the blue, their own development into the world's top existence, to take the foreigner to build high-speed rail project, to foreigners to train relevant talents, has become a commonplace thing!

In this plot, the example of the renewal of the Sanyuan Bridge in the imperial capital was taken out, which completely made the blood of everyone in front of the TV boil.

The Sanyuan Bridge in the imperial capital can no longer be used, that is, there are several highways under it, and the Sanyuan Bridge on the bridge deck is also burdened with highway tasks, and the huge bridge body is related to the use of several transportation lines, which is extremely important in places like the imperial capital that are often congested with traffic.

To replace the old method with a new bridge, it is necessary to dismantle the bridge, clean it up, and rebuild it, which costs a huge amount of time, not to mention, just the time consumed in the middle will bring great transportation pressure to the local area, and where to put it is also a world-class headache.

But in the case of so many problems, the construction team of Rabbit replaced the bridge deck as a whole within 43 hours!

Many friends pass by the bridge and don't even know that the bridge has been replaced with a new one under their feet!

In the TV, in a fast-forward way, watching the huge bridge body being cut and transported away, the new bridge was smoothly transported to the target location by several large machinery, only 24 hours, the follow-up project and asphalt pavement restoration has been completed, the whole scene is orderly and neat to the extreme, giving people a sense of beauty that shocks the soul!

43 hours!

When it generally takes months or even years to build a bridge abroad, the infrastructure capacity of his own country has reached such a thrilling level, which makes Chu Yunfei forget all his positions and entanglements, and completely applaud such a team.

Li Yunlong looked at such a scene, and his heart was also full of pride: "In the world, no one dares to bully us! Brother Yunfei, what do you say is the blood shed when you are a soldier?!"
