Each block is close together, and the treasure army will have to be careful when it comes to evacuating.

Several commanders studied it and felt that the arrangement of Commander Tan was fine.

"Mark the way with rocks, don't blow us up then." Madman Tan said uneasily: "Also, in the past few days, we must always be vigilant that Jiannu will attack in a big way, don't think that they will rein in after continuous setbacks, Jiannu is still very brave, and you can't look at Jiannu like the Korean soldiers and the Ming army." ”

"Rest assured, this is not the first time we have fought with mines." Wan Daxi said with a smile: "Jiannu left a lot of fires and jars and jars, which can just come in handy, and the jars and jars we used by Jiannu are all dirty." ”

Madman Tan smiled and nodded with the chief of staff, as well as several other generals.

The chief of staff said that he would personally take charge of the defense of the battalion and build at least two lines of defense.

Madman Tan was satisfied with everyone's statement.

"I'll give you five regiments, all of which are in squads, half for guerrilla squads and half for mine-laying squads, and the guerrilla squads cover mine-laying squads. The rest of the regiments, staying in the battalion, protect and catch up with mines! Madman Tan said: "This time, thanks to the foresight of the General Staff, it was expected that mines might be used, so we brought some accessories and materials, which will not be a problem to build tens of thousands of mines." ”

Everyone was excited when they heard it.

The materials for making mines are usually carried by the treasure army, because they do not occupy space, and the materials pulled by a carriage can make tens of thousands of mines.

Plus the guerrilla warfare of the treasure army, the main weapon is also mines.

Landmines have a history of about 500 years in our country.

Weapons manufacturers in the Ming Dynasty first invented and created landmines, which were widely used in warfare.

The Ming Dynasty military book "Wubei Zhi" records the shape and characteristics of more than 10 kinds of mines, and draws a map of the structure of mines.

Most of the mines are made of stone, pottery, and iron, and they are buried in the ground, and they use firing devices such as stepping hair, tripping hair, pulling hair, and igniting hair to kill and injure the enemy.

In the early days, most of the mines were made of stone into a round or square, with a deep hole in the middle, filled with gunpowder, and then a pestle, leaving a small gap to insert a thin bamboo tube or reed tube, pulling out the fuse, and then sealing the mouth with pulp mud, burying it in the place where the enemy must pass, and when the enemy approached, the fuse was lit and the mine was detonated. This kind of stone mine is also called "stone bomb cannon".

Its structure is simple, easy to use, and it is widely used in combat.

However, it was also gradually updated due to the small amount of storage and low explosive power. Subsequently, the shape of the mines, especially the ignition devices, was continuously improved, and the effective killing range of the mines was expanded.

The Ming Dynasty also created the official pavilion cannon and the official office cannon, which were specially buried under the official case or in the official pavilion in the official hall of the official mansion, and after the enemy occupied it, as long as it touched the ignition mechanism, the mine exploded immediately.

The mines of the Bao army were much more advanced than those of the Ming army.

Because there are dozens of ready-made patterns on the warship brought by President Wei.

In addition to the fact that there are no big ones like anti-tank mines, there are other major types of mines of the late nineteenth and early twentieth centuries.

In the early Qing Dynasty, the rulers paid little attention to the manufacture and use of landmines and various explosive devices.

It was not until after the Opium War that Ding Shoucun, Huang Mian and others began to actively develop various types of mines, mainly pulling mines and tripping mines.

Ding Shoucun once invented a kind of "thunder jumping", which was brought to Tianjin for a audition, which was very effective.

This type of mine is made of a round mine cast in iron, which is filled with gunpowder at the bottom of the cabinet and connected to the mine fuse, which is equipped with a firing device.

When using, bury the wooden cabinet in the ground first, and place a rollover next to the wooden cabinet to connect with the ignition device in the cabinet.

Once the enemy mistakenly overturns the car and pulls the ignition device, the gunpowder will explode, and the mines in the cabinet can be thrown seven or eight feet high on the ground and explode in the air, and its killing range can reach a radius of dozens of zhang, which is extremely powerful.

In 1580, when Qi Jiguang, a famous general of the Ming Dynasty, was stationed in Jizhou, he made a kind of "steel wheel fire" mine, when the enemy stepped on the motive, the steel wheel rotated and the flint was sharply rubbed to ignite, detonating the mine.

The drum firing device improves the accuracy and reliability of the timing of mine firing.

In the documents of the Ming Dynasty, there are detailed records of a variety of mines, which indicates that mines had developed to a certain level at that time, and mines only began to appear in Europe in the 15th century during fortress defense battles.

After the middle of the 19th century, the emergence of various high explosives and detonation techniques made landmines standardized and diversified, thus giving birth to modern landmines.

The crafting materials carried by the treasure army are mainly.

Disc Spring: A curved steel sheet that looks like a doughnut and is used to pad heavy loads.

Time-delay element: A compound that burns for a certain amount of time before igniting a lead or explosive.

Detonator: A small portion of explosives used to ignite a large amount of explosives.

Firing pin: A metal needle that is pressed into the inside of a detonator when a mine is detonated.

Lead: A flammable substance used to ignite explosives.

Flame: A metal rod that protrudes on the ground and detonates a mine when triggered by a person or object, also known as an ignition hydrant.

Magnetic mines: Mines equipped with magnets that detonate when a large metal object enters a nearby area.

Percussion thundercap: A compound that is detonated by impact or pressure.

Pressure plate: A metal disc on top of a mine, which can be detonated when pressed.

Projectile: A metal ball or glass shard placed inside a mine, which can aggravate casualties. The metal casing of a mine can also be turned into a projectile after it explodes.

Launch charge: A small amount of explosives at the bottom of a jumping mine, which can be pushed into the air.

Safety pin: A needle embedded inside a mine that prevents the mine from exploding when not in use.

Now that there are a large number of black fire buds, they can be assembled directly.

Black powder is made of potassium or sodium nitrate, charcoal, and sulfur. The Ming army had it, and Jiannu actually had it, and Jiannu also had firearms. It's just that the level of the Ming army is not high, and the volume of the Ming army is not large, so it is not taken seriously.

This caused the black fire buds stored in Yangguli's camp to go directly to the hands of the treasure army, which was purely crooked.

The main mines of the Treasure Army are explosive mines, which are the most common type of mines.

Explosive mines are buried a few centimeters deep in the ground, usually triggered by a person stepping on a pressure plate, and require a pressure of about 5-16 kilograms.

Such mines are designed to destroy nearby objects, such as human feet or legs.

Explosive mines can blow targets to pieces, causing secondary injuries such as infection and amputation.

Nurhachi has been waiting for news from the south gate of Shenyang City.

I didn't wait for news for a long time, and sent someone to inquire before I knew Huang Taiji's plan.

Nurhachi nodded, and didn't say anything, although he asked Huang Taiji to attack the treasure army, but this time, he didn't give an order to Yang Guli like he started, saying that he would immediately repel the treasure army.

"Yang Guli, you have suffered a big loss this time, learn a lesson, and make meritorious contributions in the future!" Nurhachi's anger dissipated a lot at this time, and he said to Yang Guli beside him.

Yang Guli's eyes were red, and he thought that the Great Khan was going to kill him.

"Great Khan, I am ashamed of the Great Khan, ashamed of the Great Golden Kingdom, ask the Great Khan to execute me!" Yanguli knelt down.

"Get up! What about your past exploits? You can't be discouraged because of a failure, that's not the hero of our Dajin country! Nurhachi regained his former heroic bearing and personally helped Yanguli up.

Everyone saw it in their eyes, and they knew that the Great Khan had praised Huang Taiji's approach and was relieved.

Everyone sighed, and only Huang Taiji dared to do this, the Great Khan asked to fight Wei Bao's army, but Huang Taiji changed it to interception and harassment, which was discounted.

After Yang Guli got up, Nurhachi noticed Cong Gulun Gege and Huang Taiji's side Fu Jin Da Yu'er.

"Huang Taiji is really bold, and when he was fighting, he brought you with him." Nurhachi said and beckoned to the favored Conggulun, signaling him to come over.

Conggulun hurriedly came to Nurhachi's side and whispered affectionately: "Father Khan, father Khan don't be anxious, Brother will definitely be able to defeat the enemy army." ”

Nurhachi sighed, "Okay, you guys go to sleep first, this is not the place you came from, I guess I won't be able to fight today." ”

"No, I'm here with my father Khan, not leaving." Cong Gulun said: "Father Khan drove me back to the house, and I must not be able to sleep." ”

Nurhachi said indifferently: "Then let it be." ”

Jiannu are all heroic, and there are not so many differences between men and women.

In this way, Cong Gulun and Da Yu'er and other female dependents also stayed, and lay down in a small room next to them.

They had to wait for news with Nurhachi, and the other high-ranking strategists and generals of the Dajin Kingdom, waiting for the news of the victory of Huang Taiji's army.

That night, the Bao army sent a small group of hundreds of men and horses in small groups to bury mines.

Others planted mines secretly, but the treasure army was not, with a posture of attacking the Jiannu Mang Gurtai Department, and occasionally two shots were fired.

Mang Gurtai had already fallen asleep in the tent he had set up, but when he heard the sound of gunshots, he woke up in shock.

"Where's the noise!?" Mang Gurtai asked nervously.

Mang Gurtai's soldiers outside the tent hurriedly said: "The general will wait for me to check." ”

"It was Wei Bao's army that secretly killed two of our rangers!" After a while, the pro-soldiers returned.

Mang Gurtai originally thought that Wei Bao's army was taking advantage of the night to launch a sneak attack, but the most disgusting thing about Wei Bao's army was not the powerful artillery fire in the front.

Rather, it is a sneaky behavior, especially preferring to shoot cold at night.

"Tell the soldiers of the whole battalion to strengthen their vigilance and prevent Wei Bao's men and horses from sneaking up on the camp." Mang Gurtai Road.

The soldiers agreed and went out to give orders.

Mang Gurtai was just about to fall asleep, when someone came to report: "General, Wei Bao's men and horses have been dispatched a lot, and it seems that they are burying mines everywhere!" ”

"Buried mines?" Mang Gurtai was a general who could fight well, and fought many times with the Ming army, and the Ming army also used mines, and knew what it meant to bury mines.

It's just that what puzzles Mang Gurtai is that the Ming army uses mines very rarely, and most of them are when defending the city.

Now it is a large-scale operation on the plains, what is the use of laying mines? How many people can be blown up?

"Send iron cavalry, in units of 100 people, send ten teams of 100 people, to drive away, to shoot, don't chase too close to the camp of Wei Bao's army." Mang Gurtai immediately ordered.

Mang Gurtai is not a reckless man, although he is not convinced, Huang Taiji is younger than himself, and he is pressed everywhere.

But Mang Gurtai will not rashly attack Wei Bao's camp.

The soldiers went to give the order.

The ten hundred-man cavalry of the Mang Gurtai Division immediately set out.

Baojun saw that someone was coming, and he was not in a hurry.

The squad in charge of the guerrilla warfare observed and urged the squad in charge of laying mines to retreat.

There are many more such classes next to it.

"It's just right that someone is coming, just to see the effect." The squad leader of the mine-burying squad laughed.

"Hurry up, it's less than 100 meters, and Jiannu's arrows are shooting very accurately!" The squad leader of the guerrilla squad urged again.

"It's okay right away, prepare to evacuate, pay attention to the secret mark when you leave, don't step on the thunder." The squad leader who planted the mine greeted everyone.

The two squads then began to retreat.

Jiannu chased after the treasure army from afar, and saw that the treasure army was gone, and the chase was even more fierce, this place was still far away from the treasure army's camp, and they were ordered to shoot the treasure army, but they couldn't get too close to the treasure army's camp.

Rumble!

With a loud bang, a Jiannu war horse soared into the air.

Stepped on a mine.

"Stop, stop chasing!" The hundred-man Kora immediately shouted.

Everyone stopped chasing, not knowing where to step on the mine again.

At this time, not far away, another team of 100 also stepped on the mine, and there was another loud bang.

The loud noises were so loud that the people in Mang Gurtai's camp could not sleep.

It also alarmed Huang Taiji's camp and Dai Shan's camp.

The main direction of the Bao army's attack was Mang Gurtai's side, which was to make a posture of advancing to Shengjing City, but it also took care of the enemies in the two directions of Huang Taiji and Dai Shan.

Dai Shan hurriedly asked people to use the flag to ask Huang Taiji what to do now.

Huang Taiji asked people to reply to the letter, and they did not move!

Huang Taiji and Dai Shan naturally also discovered the action of the treasure army to bury mines.

The root of the emperor's anger hurts, he can't beat it head-on, and he can't play these indiscriminate tricks behind his back, and he can't play Baojun, in short, they all suffer.

It seems that the Bao Army only used one move to crush Huang Taiji's plan to intercept the supply line of the Bao Army on the side.

Although he was far away, Nurhachi heard the noise.

This night, Nurhachi also did not sleep well.

Everyone ran to the castle tower to watch, only to see in the distance, from time to time there was a sound and fire.

It's just that the interval is very long, sparse, and it doesn't look like a large-scale operation.

"Hurry up and ask, and see what's going on." Nurhachi said urgently.

The soldiers immediately took the order and left.

"It seems that Wei Bao's soldiers and horses are burying mines!" It didn't take long for the people who had gone to the Mang Gurtai military camp to investigate.

Nurhachi was completely speechless this time, although Nurhachi did not personally fight the Bao army, but he did not dare to hide what was happening below, Nurhachi knew that the guerrillas of the Bao army were accustomed to using mines.

But I didn't expect that now that there are large-scale battles of 10,000 people, the treasure army is still playing with mines.

This annoyed Nurhachi.

The low level of culture has caused Jiannu not to mention making landmines, let alone clearing mines, and even literacy is not a few people.

Compared with the overall cultural level of Jiannu, almost all the millions of people in the area under the jurisdiction of the Tiandihui who have almost completed the eradication of illiteracy can be regarded as high intellectuals.

It's the crushing of technology.

In fact, on average, on average, the wealth value of Jiannu is still much higher than that of the Tiandihui jurisdiction, and they are even stronger.

But in terms of science and technology, it has been left far behind by the jurisdiction of the Heaven and Earth Society.

"It seems that Wei Bao wants to fight with us for a long time, originally he only sent a small group of about 1,000 people, but now tens of thousands of people are sending people to our territory, I am afraid that there will be no peaceful days in the future." Bao Chengxian said in a low voice.

Nurhachi knew what Bao Chengxian wanted to say, and couldn't help but think of the treaty sent by Wei Bao during the day, the indemnity of 4 million taels, the opening of Qinghe as a trade, and the permission of the Bao army to garrison troops in Qinghe, which were all terms that Nurhachi could not accept.

Not only lose power, but also humiliate the country!

Thinking of this, Nurhachi's face was constantly twitching!

"I really didn't expect that there were such brazen people in the world, such a brazen army! I really want to hack Wei Bao alive! Nurhachi said angrily.

Dressed up, Cong Guren Gege, who came out to check, just heard Father Khan's words, frowned slightly, and sighed faintly.

Cong Gulen Gege really didn't want to associate that handsome young man who was white and pure and had an elegant temperament with Wei Bao, who was now hated by his father Khan, and was trembling with anger.

Cong Gulen Gege wanted to confess to his father Khan that she had seen Wei Bao, and had been writing letters with Wei Bao.

At this time, Da Yu'er saw through Cong Gulun's thoughts, grabbed Cong Guren Gege, and shook his head slightly at Cong Gulun Gege.

Cong Gulengege's face flushed, knowing that Da Yu'er knew what she was thinking, and said in a low voice: "I think it's better to say it to Father Khan, Father Khan won't blame me, and he won't blame Elder Brother." ”

"It's not time, don't say it yet! Let's see how your brother fights, and talk about it when you can't beat it. If you win, you don't have to say it. Da Yu'er whispered to Cong Gulenge.

Cong Gulun thought about it, felt that it made sense, and held back.

The little girl's family is still relatively naïve.

Cong Gulen Gege even felt that as long as she and Wei Bao could meet above, maybe they could say that they would not fight with Wei Bao and Dajin Guo again.

Jiannu heard the movement.

Wei Bao naturally heard the movement, but Wei Bao slept soundly and was not affected at all.

President Wei sleeps like this, unless he is woken up by an artificial loud noise, or he is awakened, he will not wake up.

Although the supply line was intercepted by Jiannu, President Wei knew about it that afternoon and did not make corresponding arrangements, because Wei Bao had already guessed that Madman Tan would definitely fight back with mine warfare.

Wei Bao was very confident in the defensive power of mine warfare, so he dared to let Madman Tan lead people deep and escape from the protection of the gunboats on the river bank.

Wu Xuexia looked at President Wei, who is really fragrant, breathing evenly, handsome side face, and high nose bridge.

Wu Xuexia smiled slightly, and gently leaned on President Wei to sleep again.

The president is at ease, and she is at ease.

Although she didn't have much experience with the army, Wu Xuexia also knew through the intermittent blasting sound that this was mine warfare.

President Wei actually heard the movement, and he was in a daze, knowing what was going on.

It's just that President Wei really didn't take it to heart, and now against Jiannu, it is completely different from a year ago.

Jiannu was no longer able to threaten President Wei's safety.

Without artillery, without a sailor's Jiannu, it is equivalent to having no wings.

The more he came into contact with Jiannu, the more President Wei looked down on Jiannu.
