Traveling through the sword to engage in military industry

Xu Jiucheng's hand loosened, watching the steel piece in his hand almost return to its original shape after being released. He repeatedly bent and tested it more than ten times, and it only bent into a tiny curvature!

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

"I got a new production formula from the organization. Next, we will produce steel according to this formula." Ren Zhong said lightly, as if it were a trivial matter.

He took out the few pages of paper with the production formula and handed them to Xu Jiucheng.

"This is the new ratio plan, Engineer Xu. Next, I'll rely on you to organize everyone to produce according to the new process."

Ren Zhong didn't care at all about handing over the core commercial secret of the steel industry, worth a fortune in this world, to Xu Jiucheng.

Such high-quality steel would cost at least hundreds of silver dollars per ton. It's no exaggeration to say that if Xu Jiucheng took this and replicated Ren Zhong's simple open-hearth furnace technology outside, he could become a steel tycoon!

His wealth could reach the level of tens of millions of silver dollars, making him one of the richest people in the country, if he could find a way to protect his achievements.

Of course, the possibility of protecting the achievements is almost zero in the outside world.

Such an important strategic industrial secret would be coveted by every warlord.

With the problem solved, the specific trivial matters were left to Xu Jiucheng to handle.

Ren Zhong remembered Zhang Wanhe's instructions. Now that the open-hearth steelmaking method had also produced results, he called Zhang Wanhe, preparing to go to headquarters to fulfill the appointment, check the construction of Zhang Wanhe's two earthen blast furnaces, and hand over the open-hearth steelmaking process and production technology he had developed to Zhang Wanhe to organize expanded production.

The newly mass-produced carbon steel, judging from the initial quality, should be close to the performance of rail steel at this time. After all, although rail steel in this era is alloy steel, the impurity content is completely different from later rail steel. This new batch of carbon steel I produced has no problems with yield strength and tensile strength, and should barely qualify for making gun barrels, of course, it cannot be compared with stronger alloy steel in the future.

After all, in the world of "Bright Sword", a gun barrel that can fire 5,000 bullets is enough. It cannot be compared with the modern service life of 10,000 or even 20,000 rounds.

Because in a battle, the Eighth Route Army soldiers usually don't have more than 30 bullets, so such a gun barrel can support at least hundreds of battles. According to Ren Zhong's historical understanding, this is basically enough to last until the Japanese devils are driven out, and then it can be scrapped!

What else do you want?

Let's leave aside Ren Zhong's trip to headquarters. (Those who know, know.)

The combined area of Heyuan and Ping'an.

358th Regiment's garrison.

"Staff Officer Fang, do you have any news about which unit of the Eighth Route Army is active in attacking the blockhouses in Heyuan?" Chu Yunfei asked without turning his head, looking at the Japanese strongholds disappearing one after another on the map.

"Regimental Commander, our people still don't know the origin of this group of the Eighth Route Army, but it is certain that they are not local guerrillas from Heyuan. Their weapons are sophisticated. According to the local people, the sound of attacking the blockhouses is very loud, and the sound of heavy artillery explosions can often be heard several miles away from the strongholds. Afterwards, it can be seen that most of the blockhouse is often blown down. The explosive power is very huge." Fang Ligong, who was standing on the side, replied.

"When did the Eighth Route Army have heavy artillery? And they can bring it into the mountainous counties like Heyuan, which has rugged mountain roads, without being discovered by the Japanese devils. I always feel that there is something strange about it. In addition, this group of people appears and disappears mysteriously. I infer that the possibility of them having heavy artillery is very small." Chu Yunfei disagreed with Fang Ligong's judgment.

As one of the top students of Huangpu Military Academy, Chu Yunfei knows every type of heavy artillery above 100mm that appears in almost every war zone like the back of his hand. There is absolutely no model that can move quickly in such mountainous areas where there are no roads for cars to drive on.

Even the Schneider M1 mountain gun, which is super light in weight, also weighs more than 700 kilograms when traveling. It is absolutely impossible for manpower to easily move and transfer it. Judging from the situation of the lost Japanese strongholds, most of them are in the direction of the mountainous areas where only simple roads are passable, and horse-drawn carriages and motorcycles can barely move.

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

"Although the Japanese devils' blockhouses are not constructed with reinforced concrete, they cannot be blown down by a mere 75mm mountain gun."

"This is the key point we need to figure out. Haven't the scouts sent out gotten any news about this?" Chu Yunfei shook his head, always doubting Fang Ligong's judgment.

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

The 358th Regiment has the logistics and intelligence support of the Jin-Sui Army. Although Li Yunlong and Zhang Dabiao's activities in Heyuan are now blocked, after developing new fortress villages, it is inevitable to publicize and absorb militia to guard them, so it is inevitable that some clues will be found out by the intelligence personnel of the Jin-Sui Army.

"According to intelligence, Li Yunlong was removed from his position in the New First Regiment by the Eighth Route Army, and then, not long after, he took office as the commander of the Independent Regiment. Then the Independent Regiment has been quiet until recently. I heard that they destroyed two Japanese strongholds near their garrison, and then there was no new movement. We have few internal personnel who can penetrate the Eighth Route Army, and a lot of intelligence relies on the Eighth Route Army's reported battle results to obtain information, which is very passive." Fang Ligong is indeed the know-it-all of the 358th Regiment, and he knows all kinds of intelligence like the back of his hand.

"Oh, wait, you said that the Independent Regiment also destroyed two Japanese strongholds recently. Have you sent anyone to investigate how the Independent Regiment did it? You must know that without the support of direct-fire artillery and heavy weapons, even our 358th Regiment would not find it easy to destroy a Japanese devil's blockhouse."

Chu Yun's heart moved, as if he had discovered a trace of Li Yunlong's whereabouts.

In Chu Yunfei's heart, a bold idea suddenly emerged.
