Anti-Japanese War, weapons designer at Fengtian Arsenal

The commander of this battle was Li Jun, who was the first among the clones to receive advanced military education and had the best knowledge of this.

At this time, Li Jun was walking quickly on the high ground. He was holding a kettle in his hand. He poured white lime from the spout and drew a line on the ground. Then, a bulldozer drove over and began to dig trenches along the line he drew.

The high ground where they were was bare and had no shelter at all. When facing the Japanese army, they would definitely be subjected to fierce artillery attacks. They had to build complete fortifications to protect the lives of the soldiers.

Fortunately, with the help of excavation vehicles, it was not difficult to do this. After 6 trucks shoveled and dug, soon the high ground was filled with gullies and the outlines of trenches were dug out.

However, the trench dug by the bulldozer was very rough and needed fine finishing. The clones followed the bulldozer, jumped into the trench, and carried out more detailed excavation with pickaxes and shovels.

In order to deal with the Japanese artillery bombardment, the trenches they dug were not straight lines, but W-shaped sections. The advantage of this type of trench is that when a shell falls inside the trench, the explosion shock wave will not spread to both sides of the trench, but will be offset by the W-shaped trench.

In addition, soldiers had to dig a large number of anti-artillery holes in the trenches to resist artillery fire.

After planning the trenches, Li Jun began to set up firing points. The Liao-made Maxim rifle that fired 12.7mm bullets was a very powerful weapon. One rifle could directly control the battlefield about 2km in front of the position, so it was also the enemy's main target of artillery fire.

Li Jun told Li Qinwu that when the fighting started, the heavy machine gun would fire for one or two minutes, and the Japanese artillery shells would definitely fall. The Japanese would not allow such a terrifying heavy weapon to exist on the offensive position, so they must find a way to protect the heavy machine gun.

Li Qinwu said it was simple, just go straight to the concrete bunker!

Li Qinwu started preparing a few days ago. He asked Li Hanchao and his gang, who were hiding inside the Japanese army and working for the Japanese, to steal a large amount of construction materials and build many small machine gun bunkers on the island.

This machine gun bunker is very small and can only accommodate two people and a heavy machine gun. The bunker is made of concrete and steel bars. The thickness of the front and top surfaces is half a meter, and it should be able to withstand frontal artillery fire.

This thing is not very big and not very high, only about 1 meter, which allows this concrete building to be placed on a metal flatbed truck and then pulled out of the island space by a freight truck.

Li Jun selected several firing points with excellent views. Li Qinwu immediately opened the portal and let the truck pull the machine gun bunker out of the island space, then unloaded it from the cart and placed it at the location selected by Li Jun.

This thing cannot be used directly after it is taken out. After all, the height of the entire fortress is only a little over one meter. Excluding the one-meter thick concrete layer, the internal usable space is only half a meter.

To use this thing, you need to dig a hole in the ground and create a space for soldiers to hide in. It is equivalent to digging a hole in the ground and then covering it with a cement lid.

After 20 prepared concrete bunkers were placed on the high ground, the defense of the high ground was suddenly improved by several points. Li Qinwu felt that the ability to quickly build bunkers was very interesting, a bit like pre-fabricated meals in later generations. There should be room for development, so he had to think about it carefully.

After the machine gun bunker was completed, Li Jun asked Li Qinwu to dig a large command post underground in the center of the position.

Since the clones have the ability to share minds, they don't actually need a commander. They don't even need communication tools. With just a thought, orders can be quickly transmitted in the clones' minds. Moreover, if the commander dies unexpectedly, a new commander can be selected immediately.

Therefore, the function of this command center is not to command, but to open a portal for Li Qinwu.

He hoped that Li Qinwu could find a safe location to open a portal so that he could quickly transfer the wounded to a safe location. If the situation was very bad and the position could not be held, the clones could transfer to the command center through the dug trenches and retreat through the portal.

An army of 3000 is a large number, and it will take a lot of time to have them retreat into the island space. The Japanese front-line commanders are also very perceptive. If they find that the positions are empty, they will definitely order the soldiers to attack forward, so the retreat point must be placed in the center of the safest position, and it must be underground.

The workload was quite large, but Li Qinwu was not in a hurry and just used explosives directly!

Under Li Qinwu's command, several clones took pickaxes to the center of the position and dug a pit more than two meters deep. They threw 100 kg of explosives into the pit and lit the fuse. A shocking explosion sounded, and a large amount of earth and rocks were launched into the sky, and a huge deep pit appeared underground.

Then they repeated the same thing three more times, creating a huge hole in the center of the trench.

The clones used the wooden beams prepared in the island space and inserted them into the ground. After laying the basic structural frame, they used large bags to fill the upper level of the headquarters with soil, and then extended the trenches to the headquarters. In this way, a safe return point to the city was built.

The noise from the explosion was so loud that it alarmed the Northeast Army across the Nenjiang Bridge.

At this time, the Northeast Army was stationed opposite the Nenjiang Bridge, and the troops on a trench were Ma Zhanshan's Xu Baozhen regiment headquarters.

In the past few days, Xu Baozhen has been setting up defenses north of the Nenjiang Bridge. Their scouts in the south of the Yangtze River have learned that today, the troops of the traitor Zhang Haipeng will arrive at Nenjiang. The war is about to break out, and everyone's spirits are tense to the extreme.

There was a sudden loud explosion on the south bank of the Nenjiang River, which frightened the Northeast Army on the position. They all ran to their battle positions, thinking that the enemy had come. However, after waiting for a long time, nothing happened on the south bank.

Xu Baozhen waited anxiously in the command post, but after waiting for a long time, there was no enemy attack. He was a little puzzled and didn't know what was going on, so he sent out a cavalry team to conduct reconnaissance.

This cavalry squad ran directly to the south bank across the Nenjiang Bridge without worrying about enemy ambushes.

After safely arriving at the south bank, they quickly dispersed to scout everywhere, but they found no enemy troops at all. So where did the explosion just now come from?

Just when the cavalry team was puzzled, two more explosions were heard. Several cavalrymen looked towards the high ground in the distance, confirmed the location of the explosion, and quickly approached for reconnaissance.

The cavalry team arrived quickly at a distance of 5 kilometers. They hid in the forest below the high ground. When they saw the situation on the high ground, their faces were full of surprise.

I saw a large hill and two small hills ahead, full of people. It was estimated that the number was more than 2000. These people were doing earthwork, and criss-crossing trenches were spread all over the hills.

Moreover, this group of people found logs from somewhere and were covering the trenches with them. Then they covered the logs with sandbags and transformed the trenches into underground shelters.

The intensity of this project is unimaginable, but in just a few moments, one-fifth of the trenches on the high ground have become underground bunkers. Several cavalrymen shouted in their hearts, how the hell did they do this? When we came to scout yesterday, there was nothing here!

As they observed more closely, they found out why the other party's operation speed was so fast. They saw a forklift!

Several bulldozers were running around on the high ground, and soon the outline of the trench was completed. Explosions were heard again and again on the position. These damn people actually used precious explosives for blasting!

The cavalry captain's eyes were as big as copper bells. He put down his binoculars, rubbed his eyes hard, and slapped himself twice.

"Oh my god! Are my eyes blurry? Where did these weirdos come from?"

The mechanized construction brought a huge psychological shock to this guy who could only read no more than 10 words. He thought he was confused.

The team leader raised the telescope again and looked at the position in the distance. Then, his eyes widened again. He saw a truck with a metal cart behind it. On the cart were some strange lumps of concrete.

The truck pulled the cart to a designated location. With the help of a forklift, the concrete pile on the cart was unloaded. Then several people carried a heavy machine gun and walked into the concrete pile. This turned out to be a machine gun bunker!

The team leader put down the telescope. His face was extremely ugly. He didn't know the identity of this unit. The mystery displayed by this group of people made him very uneasy.

If this group of people were Japanese or traitor troops, then their situation would be dire. The other side converted the three heights into permanent fortifications in a short time. With their current equipment, they could not take down positions of this level at all.

If they are the Japanese troops, it means that the Japanese have a solid foothold on the south bank, which is not good news.

"Brothers, retreat quickly!"

The team leader immediately ordered a counterattack, and he wanted to bring back the news here as soon as possible.

However, just as he mounted his horse and had no time to turn it around, suddenly, 30 big men armed with submachine guns jumped out of the woods and pointed their guns at them.

"Don't move! Put down your guns and get off your horses!"

The team leader was shocked. People who are capable of reconnaissance are usually elite soldiers and have the ability to keep an eye on all directions and hear all ears. However, he didn't notice this group of people approaching him at all. The terrifying strength of these people made the team leader extremely horrified.

These 30 mysterious men have surrounded them. There are only 10 of them, and they are equipped with rifles. The other side only needs one person to pull the trigger to kill all 10 of them. They are now in a dead end.

But the team leader was unwilling to accept the surrender. He had to bring back the information he saw here.

He became ruthless and pulled out a grenade from his waist. He pulled the ring and threw it at the mysterious man, then squeezed his legs against the horse's belly and made the horse charge forward.

He thought that the grenade he threw would cause some panic among the group of people, and he should be able to take the opportunity to spur his horse and break through the encirclement of the group of people.

But something he didn't expect happened. The grenade he threw was caught by one of the mysterious men, and then the mysterious man threw the grenade more than 100 meters away.

At this time, the team leader was fully focused on escaping. He had not yet realized what a terrifying existence it was that could throw a grenade more than 100 meters. His eyes were fixed on the person in front of him, and he wanted to urge his horse to knock him away.

However, a look of disdain flashed in the man's eyes, and he threw the flower machine on his back, and stood alone in the path he had to pass.

"you wanna die!"

A fierce look flashed across the captain's face, and he wanted to urge his horse to run over this bold guy and kill him.

But when his horse reached the other person, this guy not only did not dodge, but instead took two steps forward.

Then, in the captain's frightened eyes, the other party quickly threw a punch, which hit the horse's chest. The horse screamed in pain, raised its front legs high, and threw the captain off.
