The weapon tycoon who traveled to Daqin

It was already midnight. There was a mighty team of chariots and horses beside Naofumi. Only a few of these chariots and horses were horses, and most of them were still traditional oxcarts. They were all loaded with large quantities of supplies and medicinal materials.

, weapons, uniforms, and a large number of mechanical equipment.

Shangwen spent a lot of effort to convince the King of Qin to let him go to the northern front. Shangwen successively elaborated on many potential factors and explained that if these factors are not dealt with in a short time, they are likely to cause catastrophe. These factors

Perhaps only you can solve the problem yourself.

The King of Qin strongly disagreed with Shangwen going because it was extremely cold in the north and Shangwen's body was very weak. Shangwen made a strong request on the grounds that he was resistant to pathogens. In addition, Wang Jian was worried about the frontline soldiers. In desperation,

Reluctantly agree, but must send letters every day. Otherwise, withdraw immediately.

So Shangwen organized a large amount of supplies to go together. Another purpose of Shangwen's trip this time was to start transporting heavy industrial equipment to Guyang and set up Qin's first heavy industry base there. Therefore, some of the necessary equipment, such as hydraulic presses,

The stamping machine tools were forced to be sent to the front line.

Old Man Wei must be taken away. There are nine students walking with him. The old man's medical skills are really notorious. He mainly peels off people's skin, stretches people's stomachs, or cracks open people's heads to treat them. It sounds like

It’s so creepy. So, many people don’t want to learn it, even though it’s free. But if you stay with dead people all day long, you will get sick if you don’t want to. Being able to gather nine people is already considered a great thing.

To Shangwen's surprise, Ying Yu actually came to see him off in person. Shangwen was a little touched, but at a loss. This guy actually wanted to keep communicating with Shangwen. The reason was that without him, she would not be able to handle all the things in Xianyang.

No.

In this way, Naofumi went to the front line in confusion. What happened in front of him, Naofumi did not know.

While Shangwen was heading there overnight, the Mengtian tribe in the north was experiencing unbearable suffering.

First of all, those soldiers who failed to receive treatment in the cold environment have begun to show some symptoms of pneumonia. But the military is unable to do anything. The worst thing is that due to the dense personnel, seriously ill people and normal soldiers still live together. There is a hidden danger of infection.

, completely buried.

Then, there was a lot of frostbite. The wounds began to fester. The place where the soldiers lived, coupled with rain and snow, was extremely humid, and related diseases were also spreading.

The worst situation finally happened. Due to gastrointestinal discomfort and the cold weather, the newly arrived musketeers began to show symptoms of dysentery, including vomiting and diarrhea, and the excretion area was dirty, so they began to infect each other.

The number of non-combatants in the Qin army began to surge.

"Alas," Meng Tian looked at the military reports sent by the guards from each battalion. He was very helpless.

"Go down." Meng Tian waved his hand helplessly.

"Here." The guards retreated. Meng Tian held his head with his hand as he felt a headache. What he was most worried about now was not the Yuezhi Army, because due to the heavy snow, neither side was able to launch a large-scale attack. As for his own side,

The biggest enemy is the severe cold that brings a series of

These symptoms, military doctors simply cannot treat them in time. One day they were able to control one, and the other would be sick tomorrow. The one that was under control recurred the next day. This repeated pattern made military doctors exhausted both mentally and physically. In this regard, they could only

Just take a prescription and take some medicine.

And these battle reports on his desk, without exception, are all about those in various camps who are unable to fight due to illness. Now the total number of people has increased to more than 10,000. This number is really too big. Meng Tian feels that his opponent is not Yue.

It's these diseases. If this continues, I will be completely defeated. But I am a soldier, not a doctor, so there is nothing I can do.

Just when the Qin army in the north was suffering from illness, the Zhao army fought extremely fiercely.

After the last artillery battle, Zhao Jun began to independently ponder the shortcomings of some artillery. First of all, the accuracy of the artillery was very poor. This was the first shortcoming that all the gunners gathered together. They clearly passed the above

The rear sight was aimed at the opponent, but the cannonball was misaligned and could not be fired accurately.

Then the artillery can only hit the city wall, but not the soldiers on the wall. If you bombard the city wall, how many shells must be fired to collapse the city wall. Even if it is rammed earth, it is thick enough. Direct bombardment is not feasible.

So someone suggested that the artillery be removed from the gun mount, placed in a trench, covered with shields, and bombarded directly close to the city gate. In this way, the power of the artillery can be increased, and the accuracy can also be greatly improved. This

The idea was approved immediately.

But some people came up with a more bold idea. They thought that the artillery shells could be fired straight away like bows and arrows, so that they could fly far and bombard the Yan army from above. This idea was also very good. The gunners were convinced

Zhao Jun agreed, so he adopted a two-pronged approach. Zhao Jun launched another firecracker the next day.

This time, the Zhao army mounted two artillery pieces directly on the trench. Setting up the artillery was very time-consuming and laborious. However, the artillery at a farther position was mounted directly on the mound. The Qin army's artillery mount had a maximum elevation angle of only twenty.

Five degrees. This angle was far from meeting Zhao Jun's requirements for direct fire. So they unloaded the artillery themselves and set it up on the mound.

Then the cannon started to fire. The propellant fired normally pushed the cannonball far away. Although the cannonball entered the city, the target was too big. The effect was not very obvious.

So Zhao Jun's gunners came up with another way, which was to reduce the use of propellant. And this method is one of the effective ways to reduce the initial velocity of artillery.

So Zhao Jun's gunner reduced the amount of propellant by nearly half. The artillery fired again. The shells hit the open space in front of the city wall. The power was still insufficient. A little more was needed. The gunner added 70% of the powder, but the shells unexpectedly fired.

Passed the city wall.

It almost hit the tower. So the charge was quickly controlled to 60%. At this time, an artillery shot like a mortar, and finally hit the Yan army on the tower. The morale of the Zhao army

There was a big increase, and more artillery was added.

Zhao Jun's artillery is a cannon, with a high initial velocity and a straight trajectory. By modifying the charge, the initial velocity of the artillery is greatly reduced and the elevation angle of the artillery is increased. In this way, a cannon is forced to be modified by Zhao Jun.

A mortar suitable for siege.

With the addition of mortars, more shells began to hit the tower. The Yan army suffered heavy casualties and was unable to organize a counterattack.
