After visiting the R&D and design center, Song Yuanming taught Ye Zheng how to make gasoline incendiary bombs. After giving some advice, he left without staying too long. When passing by the arsenal, the convoy stopped again for a while. The arsenal was what Song Yuanming paid attention to.

The key point is that there is no room for sloppiness. The location of the arsenal was selected and built by a group of civil engineering experts after personal on-the-spot investigation. Smaller factories, such as the barrel cold-rolling workshop and the rifling manufacturing workshop, were built directly in the caves on the cliffs.

Among them, larger ones such as weapons assembly workshops, gunpowder loading workshops and gunpowder factories cannot be hidden in cliff caves, so they are built at the foot of the mountain, with towering peaks above their heads and dense jungles surrounding them. This way

Not to mention ordinary Japanese bomber pilots, even ace pilots cannot guarantee a hit, not to mention that there are many anti-aircraft machine gun positions and anti-aircraft gun positions built around these arsenals. Flying low will attract machine guns.

Who would take the risk of the violent artillery strikes?

Other factories that emit smoke, such as power plants and smelters, are also hidden in dense forests at the foot of mountains. Chimneys are built into the mountain walls. The rerouted chimneys are thousands of miles away from the original factories. If the Japanese army

If heavy bombers follow the smoke trail to bomb, the factory may be here, but the smoke is on the other side of the mountain. This will only be a waste of bombs.

The production of the arsenal is now completely on track. After all, the production equipment of the Taiyuan arsenal was purchased from Germany by the Nationalist Government. The quality is reliable. After a short period of familiarity, the workers have been able to form a complete production capacity. Now it can produce every month

500 Maxim heavy machine guns, 100 Type 92 heavy machine guns, 500 improved Czech light machine guns, 6,000 medium-sized rifles, 300 60 mortars, and 100 combat anti-aircraft guns

, five hundred thunder cannons, one million rifle bullets, five hundred thousand machine gun bullets, one hundred thousand artillery shells of various calibers, five hundred thousand kilograms of explosives, three thousand landmines, and twenty thousand boxes of hand grenades. This kind of production

Song Yuanming was quite satisfied. According to this production volume, he could arm three regiments every month. You must know that the troops he currently has are only three divisions and nine regiments.

After bidding farewell to the arsenal, Song Yuanming and Qinan finally arrived at their last stop - the Trumpet Fortress. The main fortifications have been completed, but some ancillary facilities in the nearby mountains are still under construction, so this place is still

It was a scene of a busy construction site. Even though it was the coldest month of winter, the workers were still shirtless and sweating profusely building fortifications. Although the work was hard, everyone's eyes were full of excitement and they hoped to do this kind of work more often.

Holding cash and eating canned meat, although the work is hard, the income is not cheap. Work here for ten days and a half, and get dozens of dollars to go home, build a house, buy land, and marry a wife. This is wonderful.

life.

The main peak of the trumpet mouth is still the same as it was more than a month ago, with dense rocks and thick bushes, but Song Yuanming, who has a keen eye, saw at a glance the gray cement traces faintly seeping out between the rocks, and a dozen shooting holes of ten centimeters square in the bushes.

Looming behind the bushes, there are large and small forts everywhere on the twenty-six nearby hills marked by Mao Lao from A to Z. Countless workers are filling in the soil and planting trees on these forts to build camouflage horns.

Three defense fortifications with a distance of five meters each have been dug out on the plain at the entrance. They are all reinforced with reinforced concrete, boulders, logs and sandbags. The special operations group led by Rabbit is lying in the fortifications on guard.

In the distance are three anti-tank ditches with a width and depth of three meters. Let alone the Japanese small tanks, even the German Tiger tanks may not be able to handle such anti-tank ditches. In front of the anti-tank ditch is an

A large anti-tank triangular cone. This kind of defense made Song Yuanming very satisfied. This way, the Japs' heavy equipment would not be able to enter the bell mouth.

"General Song, you are here." Mao Yisheng, Lai Xiaosheng and other experts, dressed in short coats and covered with sweat, working together with the workers, saw Song Yuanming coming, and quickly put down their work and ran over to greet him. Song Yuanming did not expect that

Mao Lao actually went into battle in person, and he felt a little guilty: "Mao Lao, what are you..."

"General Song, this is the most perfect design plan recognized by dozens of our experts. Of course we have to build it ourselves, so that we will have a sense of accomplishment." Mao Yisheng smiled disapprovingly, and everyone

The experts also nodded one after another, their eyes shining with excitement.

"Mr. Mao, I feel really sorry for you to be like this. Why don't you take me to visit the fortress and tell me about the various design points of the fortress?" Song Yuanming rubbed his hands and said.

"This is Mao's honor. We also invite General Song to come with us." Mr. Mao said, taking Song Yuanming into the bunker on the main peak of the trumpet mouth: "General Song, this is the main bunker of the entire fortress.

The walls and the top wall above the head are one meter thick, all made of reinforced concrete mixed with boulders. Outside the fortress wall, we also used sandbags, steel plates, boulders, and logs mixed with cement to build a two-meter peripheral defensive wall. This fortress

It can completely withstand direct hits from heavy artillery shells of more than 300 mm and heavy aircraft bombs weighing 8,000 kilograms." In the bunker, Mao Yisheng proudly introduced to Song Yuanming. Song Yuanming looked at the two-meter long

Regarding the shooting port, I couldn't help but nodded. With such a thick wall, it would probably be fine even if the shells hit it directly.

"Mr. Mao, I believe that building this fortress based on the experts' design drawings is absolutely foolproof. Has the tunnel been built? How is it designed to prevent engineer blasting and earth excavation?" Song Yuanming looked at the experts and said.

Mao Yisheng continued: "General Song, several main roads in the tunnel have been built, and they are all connected by large-diameter solid cement pipes with a diameter of two meters and a wall thickness of thirty centimeters. A few branch roads are still open.

It is under construction and is expected to be completed within two days. The underground soldier dormitories, grain storage caves and arsenal have been completed, and the electrical equipment has been laid. The entire fortress can be completed within a week. Regarding defense

For digging and explosion prevention, we have built a large-capacity reservoir in the Bell-Kou Fortress and dug five water pipes underground. Once we find signs that the Japanese army's engineers are digging in, we will open the gates and release water. This will cause water leakage accidents in the Japanese army's tunnels.

"

"This is the best thing." Song Yuanming breathed a long sigh of relief. This time he robbed a large amount of arms that the Japanese army had hoarded in Xuzhou. Tokyo would definitely be furious. According to the Japanese army's style, they would definitely send troops to retaliate. This

This is also the reason why Song Yuanming repeatedly requested to speed up the construction. This is indeed the case. After receiving the telegram from the Japanese army in Xuzhou, Tokyo was immediately furious and ordered Okamura Neiji to investigate the matter immediately and completely eliminate the national army in the ninth theater, otherwise it would

He committed seppuku in front of the emperor's portrait!

Okamura Neiji was also panicked now, and ordered Anami Weiji to march to Changsha immediately. At the same time, he transferred several elite troops of the North China Expeditionary Army to the front line of northern Hunan. The second battle of Changsha was about to break out...
