Dayun Mountain, Mufu Mountain. The smoke and dust were billowing all the way, the engine sound of heavy trucks resounded through the sky, and a mighty convoy rushed towards the mountains not far away. With a creak, a medium-sized jeep at the front of the convoy stopped.

After coming down, the convoy also stopped. Groups of special forces wearing Geely camouflage uniforms jumped out of the truck, looking around with guns in their hands. Karen Rockefeller also jumped out of the truck.

I jumped up and down, holding the camera in my hand and taking pictures non-stop.

"Mr. Mao, Mr. Lai, this is Dayun Mountain and Mufu Mountain. The way up is no longer possible. We have to go there on foot." Song Yuanming helped Mao and a group of experts open the car door and pointed.

Two endless mountains in the distance.

"Okay, General Song, since the car can't get through, let's go there on foot. Fortunately, the road is not very far, so I can still hold on with my old bones." Mao Lao smiled mockingly, and Song Yuanming didn't agree either.

He scratched his head in amusement. The mountain forest they passed by on the road was the position where Song Yuanming and the others intercepted the Japanese gas bomb transport convoy during the Battle of Changsha. Looking at those long-abandoned reinforced concrete fortifications, Song Yuanming felt a burst of emotion in his heart.

"The specific concept of the fortress is this. The gap is large on the outside and small on the inside. It is commonly known as the trumpet mouth. After passing the trumpet mouth and entering Dayunshan Mufu Mountain, you can reach Xinqiang Town. It can be said that this is the gateway to Changsha's defense line. We are there

High-density concrete anti-tank cones should be built on the outermost edge of the gap, anti-infantry mines should be laid between the anti-tank cones, and three anti-tank blockade trenches should be dug behind the anti-tank cones, with a width of at least three meters and a depth of four meters, using reinforced concrete.

Reinforce, build three infantry defense lines behind the anti-tank blockade ditch. The defense lines can be built with a mixture of boulders, logs, sandbags and reinforced concrete from the mountains to increase the strength. Behind the first line is the mountain range of Dayun Mountain. On the mountain we need to build buildings of various sizes.

1. A varying number of mother forts are used to block the entire bell mouth! A large number of tunnels need to be built between the mother forts and the infantry defense line to connect the various fortifications. The hills in this area should be hollowed out as much as possible to build soldiers.

Dormitories, arsenals, grain warehouses, and wells need to be dug in the heart of the mountain. I don’t want my brothers to starve to death or die of thirst when one day this fortress is besieged by little devils.”

"General Song." Mao Yisheng listened carefully to Song Yuanming's fortress design plan, and kept recording in his notebook with the pen in his hand. "I just took a look, and there are a total of twenty-six hills that meet the requirements. I

Just use the English letters a to z instead. Build a large number of mother-in-law castles on the 26 hills between the a mountain and the z mountain. At the same time, they need to be connected by tunnels. Can I understand this? "

"Mr. Mao, your understanding is absolutely correct." Song Yuanming nodded appreciatively. It really doesn't take much words to deal with smart people.

"Are there any other requirements besides this?" A middle-aged man in a suit stood up and asked. Song Yuanming nodded: "There are still other requirements. The first point is electricity. The fortress needs electricity.

For lighting, we can bring transmission lines from Changsha City. These transmission lines cannot be erected in mid-air and must be buried deep in underground pipes, or we can directly build an independent power supply station for the fortress. The second point is

Oxygen, as we all know, the large troops are hidden deep in the mountains, and the oxygen consumption is very huge. I need a steady stream of fresh air in the passages of the fortress, so that the combat effectiveness of the soldiers can be effectively maintained. The third point is long-term

We have a plan. In this vast mountain, we cannot just sit back and rest. We need to build a series of ancillary facilities, such as arsenals, logistics bases, steel plants, cement plants, gunpowder plants, explosive plants, etc., to be prepared for a protracted war!

"

"General Song, if you think highly of the old man, I will be in charge of the electric power department. Before I returned to China, I was a doctorate in electrical science at the California Institute of Technology. There should be no problem in building the power supply part of a fortress." The middle-aged man just now said.

said.

"That's perfect." Song Yuanming shook the middle-aged man's hand gratefully, and seemed to remember something again: "I almost forgot, the fortress must be able to prevent excavation and explosion! Especially for the Japanese army's geotechnical excavation and processing

Soldiers and blasters!" This is not the alarmism or nervousness of the Song, Yuan and Ming dynasties, but geotechnical excavation, processing, and soldier blasting have always been the nemesis of the fortress. Historically, the Songshan Fortress was indeed strong, and heavy artillery bombardments and plane bombings could not break open the turtle shell.

Finally, the national army quietly dug a tunnel underground into the Songshan Fortress, and detonated thousands of tons of TNT explosives at the same time, allowing the Japanese in the fortress to take a good flight, and the Songshan Fortress was declared breached.

"We have taken note of your request. After we return, we will carefully discuss the construction plan of the fortress and strive to make it perfect. However, during the construction of the fortress, although the underground part and the hillside part will not be too eye-catching, the above-ground construction project will inevitably

There are so many people coming and going, how can we hide it from the Japanese?" Another expert raised his doubts.

"Experts, how long will it take you to build the fortifications on the surface?" Song Yuanming didn't think about the problem of exposure at first. It was only after being led by this that he discovered the stakes. Yes, the Japanese discovered how in advance.

What? They called you before you finished repairing the fortifications, and they even had to trim the hair! The experts whispered to each other for a while, and the previous expert stood up again: "If it's quick, it only takes a month, but the quality is guaranteed

It will be discounted. If you want to build a complete permanent defense fortification, it will take at least three months for surface construction alone!"

"Okay, then in the past three months, I have taken turns leading my troops to find trouble with the Japs. Firstly, I will divert their attention, and secondly, I will contain their forces so that they cannot divide their forces to attack. But experts, you must hurry up.

It takes time to design the design drawings. This "Chinese Defense Line" is related to the life and death of the Chinese nation." Song Yuanming bowed heavily to the experts. He was not fighting for this political party or that party, he was fighting for this suffering.

The motherland is in trouble, for the suffering people.

At the same time, Yan'an, Wayaobao.

In view of the current strategic situation, Mao Zedong held a special meeting to study the strategic plans of the Eighth Route Army in North China and the New Fourth Army in Central China in the next stage. Interested people noticed that at this meeting, there were no portraits of him and Zhu De, and at the meeting

The erroneous opinions put forward by some Comintern representatives were also completely rejected by the local Communists. It seemed that the Chinese Communist Party broke away from the control of the Comintern overnight and had independent decision-making and opinions. It seemed that,

It can be regarded as the contribution of Song, Yuan and Ming Dynasties.

This chapter was quite hotly written. When I wrote the last paragraph, there were a lot of sensitive words, which made me rewrite the manuscript for the fourth time. I really don’t understand how these great men have become sensitive words. It’s strange.
Chapter completed!
