The thing that cuts ties is something that will happen sooner or later. It's just a matter of the situation of the Qi army. Although wireless technology has reached the level of broadcasting, the application of wireless technology in the military field is obviously not as extensive as in civilian use, especially the front-line troops of the Qin army, and there are very few places equipped with radio equipment.

In fact, Qin Jun has noticed that radio equipment has the potential to bring about huge changes in the military field. Especially when fighting in military operations, when fighting in the vast Western Regions, the troops are often distressed by the interconnection between the troops.

In particular, the communications troops. They sometimes need to send several groups of people in a row to get in touch, and the communications unit is the most missing branch. Because the communications personnel usually act alone. Acting alone means that it is difficult to get help in time after an accident. For example, natural disasters are either intercepted and killed by opposing patrols. And it's very likely.

Later, Qin Jun chose to use a liaison machine. However, even the use of liaison planes cannot achieve accurate contact, because some troops have to be in a state of concealment, and if they want to contact, they have to actively reveal their position.

Not only that, but the contact plane is affected by the weather and sends out a lot. Especially the weather in the Western Regions. When the weather changes in the Western Regions specially. Eighth-level strong winds are easy to ** the aircraft, not only that, the aircraft in bad weather, the engine parts wear very much. And some special terrain areas. Liaison planes could not go any further. Therefore, the liaison plane is not the best choice, and it is precisely because of this that Qin Jun is interested in equipping the radio. However, radio has many limitations, especially the few tower receivers. It is only available in a big city like Xianyang in the Qin State. Because there you can pay the high cost of steel brackets. But not elsewhere, you know. There is only one country that produces steel. At present, there are only three places in the area where steel is produced, Guanzhong, the northern part of Qin, and Taiyuan. It was barely able to produce in the Shangdang area, but because of the traffic situation there, a lot of equipment was not invested. So, the area was temporarily forgotten.

Now, the Qin army is about to face the dilemma of not having any connection.

It is not a good choice to send manpower to complete the communication.

"Look, we can lay out barbed wire, and so will the enemy, and they have more barbed wire than we do. It's not easy to get through these deadly barbed wires. The major took the binoculars and saw that the Qi army was throwing out the densely arranged wire and wooden frames. These wooden shelves were enough to keep the Qin army's communications soldiers busy.

The advent of barbed wire has made the battlefield more and more complicated. And the requirements for the infantry are getting higher and higher. At the same time, the threat to the cavalry was great. According to an incomplete statistic. As long as the Qin army defends on the spot, especially for a long time, it will arrange a large number of such barbed wire. Especially since the beginning of industrial civilization, machines can only make this kind of barbed wire in large quantities. The wire drawing machine can pump out thousands of wires per hour. It can be said that the cost is very low. But the threat of such weapons is enormous.

In the northern steppe, this arrangement of barbed wire can greatly compress the charge of the Hun cavalry. Their horses could not cross the increasingly overlapping barbed wire. If it is forced, the damage to the loss of the horse is very large.

Therefore, the living space of the Huns was repeatedly compressed by the Qin army due to this cheap defensive weapon, and it was difficult to break the barbed wire fence without special infantry equipment to dismantle.

However, once this weapon is used on the infantry battlefield, then the weapon becomes a different situation. Barbed wire will push the war to an extreme. Because this is a defensive weapon, it is very advantageous for the defending side and very disadvantageous for the attacking side. Plus the rifle is getting faster and faster. Barbed wire became synonymous with death.

On the battlefield, a large number of soldiers died in front of them because of the appearance of barbed wire. At present, except for Qin's clause on infantry crossing barbed wire, no other country has a special defensive weapon against barbed wire. However, this defensive weapon has not yet aroused sufficient awareness. And no one sees it as a threat, they just think it's an obstacle. Yes, obstacles, just obstacles.

"Bang." A crisp gunshot rang out. The positions of the Qin army were in turmoil.

"Ahh A Qin soldier shouted in mourning.

"Come on, people. Medic. Fast. One soldier shouted.

"Come on, people. Someone is injured here. Hurry up. The soldier shouted.

"It's coming. Who was hurt. "The paramedics came as fast as they could.

"Oh. Damn it. The medic looked at the wound. The bullet hit the soldier in the shoulder. The injury wasn't a big deal.

"It hurts. It hurts me to death. Damn the Qi people, I'm going to slaughter him with my own hands. The soldier shouted pain and scolded Qi Jun loudly. The paramedic could not say anything. You can only look at the wound to see if the bullet has left in the body, but fortunately it is not.

"Bear with me." The medics looked at the paratroopers.

"It's good that the bullet didn't stay in the body." The paramedic said after examining the wound.

The medical staff of the Qin State first came from the spontaneous behavior of the soldiers of the Qin army. At the beginning, there were a large number of wounded and sick in the Qin army in the north. Especially non-combat attrition. While Shang Wen continued to improve the logistics facilities, he also ordered the soldiers to select some careful soldiers from the ratio of ten to twenty soldiers to learn some medical knowledge, and then let them provide medical help to other soldiers in peacetime. Medical staff should not only be responsible for healing and providing assistance in wartime, but also care for the physical and mental health of soldiers in peacetime. Every soldier is guaranteed not to get sick.

It can be said that the Qin army was the first army to popularize medical assistance.

"Bear with me, I need to heal you. It will hurt. But it's good for you, listen, trust me. The medic looked at the wounded soldier as if it were a wounded soldier.

"Really?" The wounded soldier looked at the medic at a loss.

"Hurry up. Do it. The veteran on the side couldn't stand it anymore.

The Medic nodded. He took out a bottle of gunpowder from his medical kit. Then the gunpowder was sprinkled on the wound. Then take out the lighter. Light a wooden stick.

"Oh. Stop, here's what it's about. The wounded soldier watched in horror as the medic approached the gunpowder of the wound with a wooden stick that had been ignited.

"Get out of the way, or I'll kill you. I'm ・・・・・・・," the wounded soldier shouted.

"Ah・・・・・・・h

Subsequently, the wounded soldier was unconscious.

"Poof." The gunpowder underwent a violent chemical reaction at the wound. Then the smell of barbecue filled the air.

"Whew." The medic breathed a sigh of relief, and then began to bandage. This method was generally used by the medical soldiers of the Qin army to treat wounds. In fact, Qin Jun can use saline and alcohol disinfection to treat wounds. However, it was difficult for the Qin army to provide such convenient conditions on the front line. First of all, saline is available only to the wounded who are provided with infusions at the front. In order to provide a certain amount of energy. Normal saline has always been used as energy water. As for alcohol, it fell into the hands of the soldiers as a pastime. So, doctors don't have a good antiseptic solution to treat wounds. However, if the wound is not treated promptly, it can quickly become infected. Then the soldiers had to dig up the carrion, and in the worst case, they had to amputate the limbs.

However, an accident made Qin Jun find another quick way. That is, a Yan soldier was hit by a bullet belt. The gunpowder in the bullet was ignited. The location of the ignition was exactly the wound, because there were many wounded soldiers at that time. Qin's doctors did not treat him in time, but a few days later, the doctors unexpectedly found that the wounded soldier who had not been treated was actually healed. So he examined the wound and asked about the situation. There were serious burns at the wound, which was caused by the ignition of gunpowder, but the high temperature of gunpowder and the sulfur component in gunpowder played a good role in sterilization and disinfection. But the doctor didn't know this, he knew that if the wound was lit with gunpowder, it would be a good disinfectant. Moreover, it is very easy to avoid secondary infection of the wound. The discovery was quickly replicated.

Qin Jun didn't know. Sprinkled with sulfur powder on the wound can also be disinfected. They mistakenly believed that igniting gunpowder could be sterilized.

As a result, this method began to spread on a large scale. The paramedics, in particular, have received short-term training. Learn to spread this method and then apply it to wounded soldiers. For this reason, the medics called the method gunpowder therapy.

But this approach has a big drawback. That is, the soldiers who are treated often have to endure great pain. In particular, the burning sensation that occurs when gunpowder ignites. This kind of great pain is not something that the average person can endure. As a result, many soldiers would scream when they lit the gunpowder and then fainted. But the medics have seen more. If a soldier does not faint after being wounded and is able to hold out. Then this person can be called a real man. Because very few people can stand it.

Shang Wen was unaware of this cruel medical treatment, and if he had, he would have offered to use sulfur powder. But now, this method can significantly reduce the casualties of soldiers, especially the chance of secondary infection. In contrast, the Qi army was much more miserable. They didn't know that this cruel method could save their lives. And many of them died from this secondary infection.
