Traveling through the sword to engage in military industry.

Chapter 85 Chu Yunfei's bold idea
Xu Jiucheng loosened his grip and watched as the steel sheet in his hand almost returned to its original shape after he let go. He tested it by bending it repeatedly for more than ten times, and it only bent into a tiny curvature!

"Boss Ren, how did you do it? This is high-quality spring steel, qualified enough for producing gun barrels!" Xu Jiuchen's eyes lit up, sweeping away the lifeless look from a few hours ago, and he was so excited that he almost cried.

"We have asked the organization for a new production formula, and we will produce steel according to this formula next." Ren Zhong said calmly, as if this was a trivial matter.

He took out the pages of production formula in his hand and handed them to Xu Jiucheng.

"This is the new mix ratio, Xugong. Now it's up to you to organize everyone to produce according to the new process."

Ren Zhong didn't care about handing over the world's priceless core business secrets of the steel industry to Xu Jiucheng.

Such high-quality steel costs at least hundreds of dollars per ton. It is no exaggeration to say that if Xu Jiucheng can use this to replicate Ren Zhong's simple open-hearth furnace technology outside, he can at least become a steel tycoon!
His net worth would at least be worth tens of millions of dollars, making him one of the richest men in the country, if he could find a way to preserve his achievements.

Of course, the possibility of keeping the results is almost zero in the outside world.

No warlord would not covet such an important strategic industrial secret.

The problem was solved, and the next detailed matters were left to Xu Jiucheng to handle.

Ren Zhong remembered Zhang Wanhe's instructions, and now that the open-hearth steelmaking process had also produced results, he called Zhang Wanhe and prepared to go to the headquarters to check on the construction of Zhang Wanhe's two earthen blast furnaces, and by the way, hand over the open-hearth steelmaking process and production process he had developed to Zhang Wanhe to organize the expansion of production.

The carbon steel that has just been mass-produced should have a quality close to that of the rail steel of this period. After all, although the rail steel of this era is an alloy steel, the impurity content is completely different from that of later rail steel. This new batch of carbon steel produced by ourselves has no problems with yield and strength, and should be barely qualified for making gun barrels. Of course, it cannot be compared with the stronger alloy steels of the future.

After all, in today's world of Sword and Fairy, a barrel that can fire 5000 rounds of bullets is enough, and it cannot be compared with the modern service life of 10000 or even 20000 rounds.

Because in one battle, the Eighth Route Army soldiers usually would not have more than 30 rounds of bullets, so such a barrel could support at least hundreds of battles. According to Ren Zhong’s historical understanding, this barrel would basically last until the Japanese were driven out before being scrapped, which was enough!
What more bikes do you want?

Let alone Ren Zhong’s headquarters. (Those who understand will understand.)
The junction area of ​​Heyuan and Ping'an.

358th regiment station.

"Staff Officer Fang, is there any news about which unit of the Eighth Route Army is active in attacking the artillery towers in Heyuan?" Chu Yunfei asked without turning his head as he looked at the locations of the Japanese troops disappearing one after another on the map.

"Commander, our people still don't know where this group of Eighth Route Army came from, but we can be sure that they are not local guerrillas in Heyuan. They are well-armed. According to local people, when they attacked the artillery tower, there was a lot of noise, and the sound of heavy artillery explosions could often be heard several miles away from the stronghold. Afterwards, we could see that most of the upper part of the entire artillery tower was blown down. The explosion was very powerful." Fang Ligong, who was standing aside, replied. "When did the Eighth Route Army have heavy artillery? And they were able to bring it to a mountainous county like Heyuan through rugged mountain roads without being discovered by the devils. I always feel that it is a bit strange. In addition, this group of people is so mysterious that I infer that the possibility of having heavy artillery is very small." Chu Yunfei disagreed with Fang Ligong's judgment.

As one of the top students of Whampoa Military Academy, Chu Yunfei is familiar with all the heavy artillery of 100 mm and above that appear in almost every war zone at present. There is absolutely no one that can move quickly in a mountainous area where there is not even a road for cars.

Even the ultra-light Schneider M1928 105mm mountain gun has a traveling weight of more than 700 kilograms, and it is absolutely impossible to move it easily by manpower. Judging from the loss of Japanese strongholds, most of them were in mountainous areas that were only accessible by simple roads and could barely be moved by horse-drawn carriages and motorcycles.

"But if it's not heavy artillery, how do you explain the fact that they can often destroy a blockhouse with just one shot?" Fang Ligong asked in return.

"Although the Japanese's artillery towers are not constructed with reinforced concrete, it is not possible to destroy most of them with just a 75mm mountain cannon." "This is the key point we need to understand. Didn't the spies we sent out get any information about this?" Chu Yunfei shook his head. He still had doubts about the other party's meritorious service.

"There is no useful information about the heavy artillery for the time being. However, in the areas where the artillery towers were destroyed by the Eighth Route Army, it is said that the Eighth Route Army guerrillas have become quite active. Now traces of guerrilla militia can be found in every village near these strongholds." Fang Ligong said.

The 358th Regiment has the logistical and intelligence support of the Shanxi-Suiyuan Army. Although the news of Li Yunlong and Zhang Dabiao's activities in Heyuan is now blocked, after the development of a new fortress village, it is inevitable to publicize and recruit militia guards, so it is inevitable that some clues will be found out by the intelligence personnel of the Shanxi-Suiyuan Army.

"The Eighth Route Army has always done its work more thoroughly than us. Alas, we are powerless to do anything about these things." Chu Yunfei sighed.

"How is Li Yunlong, the man who defeated Colonel Sakata, doing now? Why haven't we heard any new news from them on the military front? This man is both brave and resourceful, and he is a fierce general in the Eighth Route Army, which is full of talented people." Chu Yunfei turned around and asked about something else.

In the battle of Cangyun Ridge, Li Yunlong did the opposite and fought head-on against such a strong enemy as the Sakata Regiment and broke through the encirclement. This gave Chu Yunfei a great shock. This was simply not a magical battle that a top student who graduated from a military academy could fight.

"According to intelligence, Li Yunlong was removed from his post in the New 358st Regiment by the Eighth Route Army, and then he became the commander of the Independent Regiment not long after that. Since then, there has been no news from the Independent Regiment until recently. We heard that they eliminated two Japanese strongholds close to the base, and there has been no new news. We have few insiders who can infiltrate the Eighth Route Army, and a lot of intelligence depends on the battle results reported by the Eighth Route Army. It's very passive." Fang Ligong is worthy of being the know-it-all of the th Regiment and is familiar with all kinds of intelligence.

"Oh, wait, you said the independent regiment also destroyed two Japanese strongholds recently. Have you sent people to scout how the independent regiment did it? You know, without direct-fire artillery and heavy weapons support, it is not an easy task for our 358th Regiment to destroy a Japanese artillery tower.

Chu Yun's heart moved, as if he had discovered some clues about Li Yunlong.

A bold idea suddenly emerged in Chu Yunfei's mind.
