looked at Zhang Sixing in front of him in surprise, although he was engaged in engineering, Engineer Wei still cared about current affairs. Glancing at Zhang Sixing carefully, he stretched out his two hands and only clasped Zhang Sixing's hands, and shook a few times enthusiastically and excitedly,

"You're the officer who is called the Four Elements Demon King by the Japanese?"

To this, Zhang Sixing also replied politely,

"That's all the devil's nonsense, and Zhang Sixing is currently the principal of the paratrooper school."

Regarding Zhang Sixing's identity and status, this Wei engineer obviously didn't care much, but couldn't help discussing with him the material problem of the road construction in front of him.

"Principal Zhang, how did you come up with the idea of using this material to produce pavement, do you know how expensive phenolic resin is, used to pave ......?"

As soon as he heard Zhang Sixing, he knew that the Wei engineer in front of him had mixed phenolic resin with epoxy resin.

"Wei Gong, this is not phenolic resin, it uses a binder called epoxy resin. The main materials are wood fibers, hemp fibers, and some other materials. Moreover, the Tang consortium has its own resin factory, so its cost is not very expensive. ”

In the face of domestic engineers at this time, Zhang Sixing certainly would not drag out the structure of his product entirely.

Looking down at the material under my feet, I couldn't believe that the thick board under my feet was actually made of wood and hemp fibers. However, Wei Gong obviously did not care how this kind of slab was made, he just wanted to know what the difference between this material and other building materials was.

"Principal Zhang, according to what you say, these are plywood?"

Wei Gong really couldn't think of how plywood could have so much strength and wear resistance. What he had just observed with a magnifying glass was the degree of wear and tear on the horizontal stripes on the roads that had apparently been used.

Regarding his questioning, Zhang Sixing replied heartily,

"yes, it's plywood, or a type of plywood. Moreover, we have achieved mechanization of this plywood, and initially realized the production of automatic methods. ”

In a word, Wei Gong stopped talking, he knew that once something was automated, its cheapness could not be explained by a simple sentence.

After all, this era is still in the late stage of mechanization, and electrification has not yet officially begun. However, at this time, people are already anticipating the future of automatic production, and once the production of industrial products is automated, it is almost worthless except for raw materials.

"Principal Zhang is lonely and unheard, so what about the load of this material?"

"Ah, Wei Gong, you are asking the wrong person, how do I know what its load-bearing capacity is. However, we have used this material to make both roads and bridges, and the load bearing should be good overall. It's better to do this, there should be a construction road near us, I'll contact you, let's go to the construction site to see. ”

After saying that, Zhang Sixing beckoned to Hansen,

"Hansen, ask the old cigarette bag, where is there a road construction site near here, it is best to have a bridge to be built, let's go to the site to see."

When he saw Han Sen take out a walkie-talkie that was only the size of a book, Long Hong and Liu Jianzhang, who were not paying attention to his conversation with Wei Gong, looked at each other in surprise.

You must know that at this time, Huaxia's radio communication was almost only stuck in the wireless telegraph, and as for the walkie-talkie, it was still a piece of equipment at the Arabian Nights. As Hansen sent out a communication request with a call sign and a secret language, he soon received an answer from the walkie-talkie.

Although Long Hong couldn't understand the meaning of those secret words, it was clear that Hansen already knew the information he wanted. And another thing shocked Long Hong and Liu Jianzhang even more.

Although this place is not far from Kunming, it is more than 100 kilometers away, and it is unbelievable that such a gadget can connect more than 100 kilometers away.

This kind of walkie-talkie was originally a radio station for cars, but before coming, Zhang Sixing estimated that the wheels of this trip would probably be directly bought by the Dian army, so people had already dismantled the car radio.

The communication distance of the car radio is 30 kilometers because it is powered by the car's battery.

Liu Jianzhang, who received the instructions from Long Hong's eyes, moistened his lips and was slightly dry because of excitement before he spoke to Hansen,

Hansen...... Uh, No, Second Lieutenant Hansen, do you have that kind of walkie-talkie? ”

"This, this is called walkie-talkie, also called walkie-talkie."

Regardless of Hansen correcting his title, Liu Jianzhang then asked,

"Second Lieutenant Hansen, we're still far from Kunming, this ...... Can something so small be connected? ”

Hansen, who took the antenna back, pointed to the sky with his chin,

"See, air defense generator, with that thing in it, it can be relayed, so it's not very difficult to contact Kunming."

It's not too difficult, such a long distance, and only the radio can contact you in normal times. Now such a gadget can be connected so far. And the air defense generator, as the name suggests, is an air defense belt power generation, it is hard to imagine that because of its existence, it can make this walkie-talkie communicate so far.

Liu Jianzhang, who heard Hansen's explanation, looked up at the sky, and a balloon like a big-headed doll was floating in the sky in the distance.

At this moment, air-proof balloons are not an uncommon thing in Yunnan, no, it will be a bit unusual to be able to generate electricity. Because of this feature, many troops privately purchase this inexpensive equipment, and the most important reason is that they need electricity when they are stationed.

But now, Liu Jianzhang didn't expect that such a cheap thing could make the communication of walkie-talkies reach more than 100 kilometers, which is simply shocking.

The communication capability of the Chinese troops, even if it is a fruit army, and the troops below the brigade level can only be maintained by field telephones, as well as cavalry and infantry communication troops. On the battlefield, such communication capabilities are clearly not enough.

Although the officers were very distressed, the commanders of the Guojun and the local troops were also distressed by this matter. As soldiers, they are well aware of the importance of communication in warfare.

So much so that in future wars, at the very beginning, they will try to attack the communication hubs of the other side, such as the Gulf War.

But now in China, the electronics industry is almost blank, and there is no ability to manufacture these equipment. And it is not only the lack of the industrial chain, but even the lack of the entire knowledge chain.

Therefore, as soon as they saw Han Sen take out the light communication equipment, Liu Jianzhang and Long Hong's eyes lit up. They quickly exchanged glances, and Liu Jianzhang spoke,

"Second Lieutenant Hansen, this thing...... You paratroopers ...... this thing Uh, is it the Tang Consortium Kunming Industrial Park, do they also produce it, is it expensive, can you buy some for us? ”

"This ......"

Hansen hesitated, and the light in Liu Jianzhang's eyes dimmed because of this, but Hansen, a guy who likes to joke, took a deep breath before saying,

"Selling, the product is produced to sell, the only problem is that it is a bit expensive."
