Traveling through the sword to engage in military industry

"What are these things?" Kong Jie looked at the few handsets, picked one up with curiosity, and examined it, having never seen one before.

It looked quite exquisite.

"Old Kong, these are for communication. Look, twist this knob here, see the green light? Then press here and speak into it, and the other person holding one of these can hear you."

Ren Zhong looked at the six handsets, randomly picked two, turned them on, and spoke into one: "Hello, hello!"

The other handset immediately transmitted the sound.

"These can be used to talk, how far can they transmit?" Kong Jie was both surprised and delighted. He hadn't expected Ren Zhong to bring back such great things this time.

"If it's flat ground without any obstructions, you can hear it from up to ten li away. In mountainous areas like ours, as long as you don't cross a major mountain peak, six or seven li shouldn't be a problem," Ren Zhong said.

These things were labeled as being able to communicate over ten kilometers, but the actual distance for guaranteed call quality was probably only five or six kilometers.

"That far? Then when we have cannons in the future, these things will be extremely useful for the artillery," Kong Jie, although not as cunning as Old Li, was still a veteran with plenty of combat experience, and immediately saw their value on the battlefield.

"Can these things be purchased in large quantities? If we had one for every platoon, it would be so convenient to command. There would be no need for signalmen running around everywhere to deliver orders, we could just use these things to issue instructions quickly."

Ren Zhong naturally knew these things.

In fact, modern troops used much better communication equipment than this.

"There might be some issues with buying these things in large quantities, but equipping the Independent Regiment down to the platoon level shouldn't be a big problem," Ren Zhong said.

"These need to be charged, and later we'll provide hand-cranked generators to charge them."

The current Bright Sword world was a typical agrarian world, and electricity was a very scarce commodity, only available in large cities.

Ren Zhong would later have to purchase a batch of hand-cranked generators to temporarily solve the charging problem for the handsets.

"I'll try it out first, I'll go find Old Li!" Kong Jie excitedly took one of them and quickly ran towards the place where Li Yunlong was building the blast furnace.

After working hard for two weeks, Li Yunlong had finally built the earthen blast furnace.

The two blast furnaces were about ten meters apart, perfectly spaced to stagger the loading of materials and the collection of molten iron.

When Kong Jie arrived at the construction site, he found that Li Yunlong and his men had basically completed it.

"Old Kong, you said that when our furnace is fired up, the smoke and dust will probably be considerable. If smoke rises, the Japanese devils might discover what we're building from the air," Li Yunlong stood in front of the blast furnace, his eyes bloodshot, clearly having spent the last two weeks almost sleeplessly building it. Old Li's fatigue index must have been maxed out.

"If we want to completely hide from the Japanese devils' reconnaissance, we'll have to stop burning coal when the Japanese planes come," Kong Jie glanced at Li Yunlong, "Old Li, take it easy, don't exhaust yourself so much that you can't even fight."

"It's easier said than done, how can we guarantee that the intelligence observed by the remote sentry posts will be quickly transmitted back?" If it's several kilometers away, it would take at least an hour or two to go back and forth, and it would be too late.

In the past, there were simple ways to transmit simple information remotely, such as message trees. But in these mountains, that method is obviously not very practical.

"Now we have this!" Kong Jie said to Li Yunlong with a smile.

Then he turned on the machine, "Hello, hello, Ren Laodi, are you listening?"

Kong Jie pressed the talk button and sent out his first sentence in the handset.

"Yes! Old Kong, did you see Old Li?" Ren Zhong's voice came from inside.

Li Yunlong looked as if he had seen a ghost.

"What is this thing?" Li Yunlong asked, pointing at the handset.

"It's basically a toy, Old Li, what do you think of this thing?" Hearing Li Yunlong's voice, Ren Zhong asked from the other side.

"It's amazing, this thing is so small and can still communicate. Ren Laodi, your organization is really too powerful. As far as I know, how can people make such a small thing? I don't think ordinary people can make it at all."

Although Old Li was not an expert, he still had basic life experience. The handset was so small and could achieve the function of a radio station that was so huge. This was a bit outrageous.

"Of course, this is our exclusive patent and will not be authorized to others to produce, so in terms of confidential remote communication, our system is independent and controllable," Ren Zhong did not beat around the bush and explained directly.

This was the benefit of being in Li Yunlong's Independent Regiment. When encountering these things, at most they would give an explanation, as for how much money, that was hard to say.

Kong Jie hadn't been here for a few days, and looking at the huge blast furnace in front of him, at least fourteen or fifteen meters high, coal had to be calculated by the basket. If so much coal was burned, wouldn't it soar into the sky?

"In the past, we were very troubled, but now it's not a big problem. Now that we have remote communication handheld radios, we can put the air defense sentry post on a mountain farther away, and report in time if there is any situation, so that we can extinguish the furnace here," After Kong Jie completed the conversation with Ren Zhong, he already felt very amazed by this handset.

It was equal to being able to report and discuss countermeasures at any time within a few kilometers.

"Old Kong, did Ren Laodi bring many of these things over?" Old Li immediately tasted the flavor.

This thing was too convenient for communication on the battlefield. If each platoon had one, then they could command down to the platoon level at any time!

If there was long-range artillery fire, the communication between the artillery observer and the artillery position could rely on this. At this stage, this was something that even the Japanese devils would find difficult to do.

The Japanese devils' artillery observers contacted the artillery by relying on a heavy radio carried on the signalman's back.

"Ren Laodi said that more can be purchased. Old Li, this thing is really too convenient to use," After Kong Jie connected to the handset with Ren Zhong, he was separated by a small mountain, and the sound could still be heard clearly, indicating that Ren Zhong's introduction was a bit conservative. It was already six or seven li away!

"That's great." Li Yunlong took the handset and carefully examined it for a while, and found that it was exquisite other than being exquisite. They couldn't see anything at all.

At the same time, having received more things, no one now disbelieved the new things that Ren Zhong had created.

So far, Ren Zhong had really never fooled them with anything.

"Old Kong, call Ren Laodi, our blast furnace is built, please ask him to guide us on how to refine iron next," Li Yunlong said to Kong Jie, he hadn't forgotten that his main job now was to produce iron and steel.
