Traveling through the sword to engage in military industry.

Chapter 75 New Upgrade

I made a deal with the brigade commander and sold him 5 walkie-talkies. The hand-cranked engines and batteries were given away for free. I also sold him 6 kilograms of penicillin. After rounding off the decimals, I easily earned 30 oceans from the brigade commander, or paintings and calligraphy by famous people.

After selling some of the things that Ren Zhong had been moving with great effort during this period, the system prompts were upgraded again!

“Draw the sword and travel through the system.

Current time and space: April 1940, Yang Village, Daxiawan.

Countdown to return: 5:19:28.

Points: 109200.

Do you choose to return?

Return address 1: Yangcun Cave, Daxiawan, Jinzhong.

Return address 2: None.

No option to return to the last crossing point (currently you can choose to cross within 100 kilometers of the crossing point). "

It turned out that after this period of material transactions with the independent regiment, even though Li Yunlong had not paid a dollar yet, the system still calculated the points according to the quantity of materials. Nearly 3 tons of copper and some handheld batteries and other materials had accumulated to more than 1 points unknowingly. Combined with the more than 2 points from the previous transaction with Zhang Wanhe, after the big deal with the brigade commander was completed, the transaction volume suddenly exceeded 10 dollars.

This stupid system was obviously calculated based on a tenfold points upgrade, except that after the upgrade it only added an alternative crossing point, which could move the return crossing point from the starting point to a radius of one hundred kilometers.

For Ren Zhong, who is hiding in Yangcun, it is basically useless now.

After taking a look at the newly upgraded system and making sure there were no other changes, Ren Zhong ignored it and continued with his work.

Using the open-hearth steelmaking process, the first steel plant was added to Yangcun!

Some of the drawings that Professor Hu had modified had been sent over. Ren Zhong directly printed out a copy to take with him. Most of the Martin open-hearth furnace devices were crude and clumsy. The only ones that were a little difficult for Yang Cun were the valves, air regulating valves, air reversing valves and gas reversing valves, as well as the gas pipelines. Ren Zhong directly placed an order with the Chengxin Machinery Processing Factory to process them!

These devices are not heavy, and Ren Zhong can take them back to the world of Bright Sword.

At the same time, the No. 4 and No. blast furnaces, which were replicated according to the No. and No. blast furnaces in Yangcun, as well as the other four blast furnaces that the brigade commander planned to build at the military district headquarters were all being built against the clock.

After the adjustment and optimization of the ingredients, the No. 10 and No. blast furnaces can now stably produce nearly tons of molten iron every day!
Considering the volume of the blast furnace of 15 cubic meters, the utilization coefficient of this blast furnace is quite touching, which is more than twice the utilization coefficient of a normal blast furnace of more than 2. If it were placed in the main plane, even if a private operator of this blast furnace in a small mountain village would suffer such a loss that even his parents would not recognize him.

But in Yangcun 40 years ago, these two blast furnaces were visited and inspected by the leaders of the base’s divisions, brigades and headquarters at all levels!

The boss also gladly wrote inscriptions for Yangcun No. 1 Blast Furnace and Yangcun No. 2 Blast Furnace, but these two calligraphy works were privately collected by Ren Zhong and were not intended to be posted on the blast furnaces.

From being a 996 office worker to being a 007 hardworking emperor, Ren Zhong actually felt happy.

I feel a little mentally unhealthy.

However, this is in the world of Bright Sword. When he arrived at the main plane, Ren Zhong resumed his normal working state.

At least, in the eyes of the three brothers, Ren Zhong is just an idler.

Lisai Battery produced the first batch of lead-acid batteries for the Sword World according to Ren Zhong's new specifications - mainly the shape is suitable for Ren Zhong to carry, and the output is suitable for the Sword World. Before the hydroelectric generators and wind power came into play, Ren Zhong's power supply to the Sword World mainly relied on hand-cranked power!
Of course, in this day and age, mobile power supplies are only so reliable, and batteries are too expensive for this world.

According to historical records, in 1941, the 113332th Division used various connections to purchase communications equipment, spending a total of 82328.75 yuan (dollars) on various batteries and yuan (dollars) on radio equipment. The batteries were much more expensive than the equipment.

Because the Japanese strictly blocked the sale of electronic products during this special period, it was extremely difficult for the Eighth Route Army to buy large batteries for radios. There was no other way, so they often used small dry batteries from flashlights instead.

However, even if the radio used was a 2.5-watt radio with the lowest transmission power, the transmitter voltage was 180 volts, so 120 batteries had to be connected in series; the receiver voltage was 45 volts, which required another 30 batteries. The most commonly used long-range radio usually had a transmission power of 15 watts, which consumed even more batteries. Once used, even if the power supply was connected, the neighbor's lights would dim. This consumption of batteries was very large.

Ren Zhongrangli customized a large-capacity lead-acid battery with no labels or logos, with a specification of 12V12AH and a single weight of 4 kg. So for a field radio, 15 batteries can be used, and the weight is exactly 60 kg.

One person carries the radio and the other carries the battery, and the movement can be carried out.

With Ren Zhong’s current carrying capacity, he can just carry one group at a time!
Ren Zhong searched on the Internet and ordered 8 unbranded, three-no, and over-powered maritime walkie-talkies for the brigade commander. The transmission power of a normal civilian walkie-talkie is 25W, and this one uses very high frequency (VHF) communication with a transmission power of W!

The maximum unobstructed communication range in VHF mode has been expanded to 25 nautical miles, which is about 46 kilometers away. Of course, it also supports UHF mode, which can communicate up to 15 kilometers in mountainous areas. For the brigade commander, this should be the best choice at present.

A 12V lead-acid battery can just power this over-standard walkie-talkie.
Of course, the price of this kind of walkie-talkie is also very touching. One costs 2000 yuan. Ren Zhong negotiated a wholesale price of 1800 pieces, and finally gave a % discount, and it arrived for !

Giving the brigade commander 100 silver dollars each, if it was simply exchanged into ordinary silver dollars, Ren Zhong could only make silver dollars at most, which was just times the profit. Compared with the more than times profit from Zhang Wanhe's calligraphy and painting transactions, it was extremely cheap.

Even if SF Express is used for expedited delivery, it will still take 48 hours for the delivery to be made by land, which means it can be delivered 3 days after the agreement with the brigade commander.

Yangcun.

Ren Zhong returned with the finalized Martin open-hearth furnace process drawing and several valves processed by Chengxin Machinery Factory.

He came to the No. 1 blast furnace carrying a large package.

"Brother Ren, can we install the valve today?" Kong Jie had arrived a long time ago. After Li Yunlong took action, Kong Jie automatically assumed the role of Li Yunlong's hard-working emperor.

I led people to work in three shifts on the construction of the Martin open-hearth furnace.

After some hard work, the simplified version of Martin open hearth furnace has taken shape.

The remaining jobs are more technically difficult.

"The valve has been delivered." Ren Zhong put down his heavy bag and said, "Let's try to install it today."

The pipeline is a fired earthenware pipe. Although it looks plain, it is resistant to acid, alkali and high temperature. The only problem is that the connection and sealing at the joints are difficult to handle. After the two sections with one end larger than the other are connected in series, they need to be carefully sealed with clay and then buried with soil. Fortunately, there is no need to consider future operation and maintenance, and the goal is to keep it connected and usable. After this treatment, there will be no major problems using it for a few years.

Near the valve, Ren Zhong brought several seamless steel pipes. He first connected the seamless steel pipes with the clay pipes and buried them in the soil to fix them. Then he installed the valves on the steel pipes. Ventilation control was used here. After wrapping the pipes with some silk and linen fabrics, they were tightly connected with the valves by rotating them. A pipeline combining clay and foreign elements was completed.

Although the connections of earthenware pipes are difficult to make, the layers of clay seals mean that for this kind of low-pressure gas flow, the leakage will basically not be too large.

Just pay attention to controlling the valves at both ends and adjust them normally.

After all this busy work, a simple Martin open hearth furnace was completed.
