The problem of Yan borrowing troops from Zhao was mainly related to the conditions. However, under the actual regulation of the Qin state, the Zhao state promised to send troops to the Yan state. But Yan had to provide Zhao with more than two million stone of iron ingots and more than ten million stone of coal. Zhao provided him with about 20,000 troops to help stabilize the front.

The Qin State also benefited from this, that is, the Yan State had to purchase large-scale weapons and equipment in the Qin State in accordance with the procurement plan formulated by the Qin Army and the Zhao Army to provide it to the Zhao Army. The Zhao army, on the other hand, used the weapons and equipment it provided to equip the special mixed division composed of four special mixed brigades to fight.

The above transfer was done nervously in the telegram. Zhao State, on the other hand, nervously dispatched military forces to complete the dispatch of troops. According to Li Mu's plan, first of all, Zhao Jun should draw some experienced combat troops for expansion. These expansions will be a key link in integrating the combat effectiveness of the Zhao army.

Zhao Jun's plan for integrated combat effectiveness was formulated in accordance with Li Mu's requirements. Because the weapon element accounts for more than half of the combat effectiveness. When the Zhao army and the Qin army were fighting in the Western Regions. Li Mu felt that the Qin army had given full play to their huge role in terms of firepower superiority.

Smooth supply lines, as well as the importance of firepower superiority, infantry has infantry artillery, infantry machine guns constitute a fire covering network, infantry machine guns, rifles constitute a fire range of 300 paces away. Outside the five hundred were assisted by mortar action, machine guns, rifles, mortars. In Li Mu's heart, a perfect light infantry firepower covering network has been formed.

And in terms of artillery killing. Heavy five-inch howitzers worked relatively well. This flowering artillery is very effective against infantry, especially artillery coverage in a certain area. Li Mu suggested that a howitzer artillery regiment be specially equipped at the brigade level.

For light artillery used by infantry. Li Mu believed that it was necessary to equip it, because the fortifications were also improving. This flat-firing gun with a straight trajectory was much more effective against reinforced concrete defensive pillboxes.

Secondly, Zhao Jun should integrate the remaining combat soldiers in the country. The operational thinking of these combat soldiers is still stuck in the era of using cold weapons. Especially when it comes to weapons. The Zhao army also has a certain number of combat units with cold weapons. And even the units that use thermal weapons have not improved the tactical aspects of the new weapons very much. In terms of drills. The local garrison of the Zhao army actually drilled according to the tactics of the Qin army using smoothbore guns.

A neat line of people marched forward with guns on their shoulders. In the face of heavy machine-gun fire, it was undoubtedly suicide. In fact, there was no way to do this, because the native troops of the Zhao army were equipped with a large number of backward smoothbore rifles. This rifle does not shoot as long as a bow and arrow. However, in order to exert combat effectiveness, this can only be done in this way. Li Mu's plan is to take advantage of this opportunity. Zhao Jun carried out a weapon update. At the same time, the troops with rich combat experience in the Western Regions and the northern steppes were mixed with these local garrison units. In this way, the combat effectiveness is increased.

Li Mu's last thought was to improve the Zhao army's operational and tactical thinking by fighting with the Qi army. The Zhao army could only try to maintain a weapon level with the Qin army in terms of weapons. But the internal level of weapons needs to be compensated for by tactics. It is impossible for Qin to export advanced weapons to Zhao on a large scale. It's a fact.

After Li Mu's speculation, it was possible for the Qi army to surpass the Qin army in terms of tactics. Because the Qi army was more flexible in terms of infantry tactics. Big changes. And it can adapt to the changing battlefield environment. On the contrary, it was the Qin and Zhao armies that did not change much in terms of tactics. Because the Qin army and the Zhao army fought against a small number of nomadic tribes in the Western Regions and the north. These tribal weapons were extremely backward compared to the Qin and Zhao armies. The Qin army and the Zhao army relied on advanced weapons, even if they dispatched tens of thousands of people, they could drive straight in.

It is precisely this huge difference in the algebra of weapons that makes it impossible for the Qin army and the Zhao army to have a lot of room for tactical improvement in tactical application arrangements. The Qin army can take advantage of its developed scientific and technological advantages and industrial production capacity to form a huge war advantage. But what about Zhao Jun? It is impossible for Zhao Jun to have such a foundation. So, consider it from this point. Li Mu strategically believed that the Zhao army should not advance too much in the direction of the development of the Qin army. On the contrary, Zhao Jun should be independent and self-innovative. Another distinctive way of thinking about military operations has been formed.

As for the national industrial base. This can only depend on the development situation of Zhao's own economy. Li Mu made a long-term plan.

Just when Li Mu took advantage of this opportunity to integrate the country's military forces. Yan Guo was very anxious. Because the Qi army has advanced to a depth of more than 200 miles in the Yan Kingdom. Although there is still a certain distance from Yandu. The exact distance cannot be calculated. Because the results reported from the front need to be reported in a day or two for exact information. The transportation situation in the south of Yan is very poor, so bad that the logistics and supplies need to be transported by detour to Zhao and South Korea, rather than directly from the south.

But just when Yan was very worried. A strong stream of cold air from the north and south merged with the warm and humid air flow from the south to the north, causing widespread snowfall, which just helped Yan Guo.

This powerful cold air came from Siberia, and the cold air was unusually cold. In the previous few days, the northern front line had been covered with a thick layer of snow. The temperature dropped to more than minus 20 degrees Celsius. It was the first time that many soldiers of the Zhao army felt such cold weather in the north.

"It's cold." The soldiers of the Zhao army, who had just returned from outside, quickly approached the fire with their guns in their hands to keep warm.

"It's just too cold." Another Zhao soldier complained.

"yes. It's too cold. A man chimed in. While others reach out for warmth.

"Hey, get up. Go outside and take a snow bath. A Qin sergeant came in and said loudly.

"It's such a cold day. What a bath? The soldier Zhao Jun said in disgust.

"What cold. Wash it and it won't be cold. As he spoke, Sergeant Qin pulled up a Zhao soldier who was shrunk into a ball and dragged him out. Then one by one they were thrown. Subsequently, the soldiers of the Zhao army and the soldiers of the Qin army stripped naked and took a snow bath in the snow, and only in this way could they quickly adapt to the cold weather in the north, and if they continued to bake the fire, it would only get colder and colder. It's basic common sense. The Qin army, who had learned to take a snow bath, had adapted to the cold winter in the north.

The Qin army and the Zhao army took a snow bath in the north. But for the Qi army, which was advancing rapidly, it was a serious disaster.

"Drive. Drive. Syllable. A crisp whip resounded through the sky. A Qi artilleryman struggled to whip his horses and pull their cannons. The sky was overcast, and it was raining and snowing.

"Damn the weather. There is also this Yan country breaking the road. An officer scolded grumblingly.

The other soldiers struggled to push the large wooden wheels of the cannons. They are also reluctant to move forward in such weather. The rain and snow had soaked their clothes. But they couldn't feel the cold above and below, because they were already pushing the cannon forward on the dirt-covered road. But when the cannon sank into the dirt, it could no longer move. And the soldiers were all dirt, and each one was a clay figure.

This precipitation is very strange. It was still raining heavily the first day. The rain soaked everyone's clothes at once. But in the early hours of the next morning, the snow began to fall. The clothes of the Qi soldiers were all wet, and in terms of logistics and supplies, everyone only had a blanket. These blankets were captured by the Yan army. Some of the soldiers did not even have blankets. The Qi soldiers who felt the cold could only cover themselves with the only military coats, trophies and blankets from the Yan army, and then curled up inside to warm up and sleep as much as possible. And the soldiers who did not have these could only suffer from the cold, and for this reason, the number of people suffering from typhoid fever in the Qi army rose sharply. But the next day, I moved on. But it was still snowing, and by noon it was sleet again. This hellish weather is about to torture the Qi army to the core.

Most of the soldiers of the Qi army did not have a change of clothes, and the continuous rainy weather made their clothes not dry, so they could only continue to move forward in wet clothes.

The horses of the cavalry unit were okay, and many cavalrymen dismounted and led their horses forward. The bicycle troops got off and pushed their bikes forward. The roads in the southern part of the country are simply terrible. Many of the roads are not big roads, but dirt roads formed by stepping on dirt, and they are usually fine, but they are afraid of raining. The road simply cannot move forward. Even horse-drawn carts, ox-carts were difficult to walk. And even more so cavalry, bicycle troops. The worst thing was the artillery and baggage units of the Qi army, which were not only heavy but also slow, and the roads were becoming more and more difficult to walk. This slow pace of progress has been exacerbated.

From the beginning of the precipitation, the pace of the advance of the Qi army began to slow down. The offensive forces advancing of the Qi army were greatly impacted. Another hidden danger is that the non-combat attrition of the Qi army is expanding.

Qi soldiers were given short leather boots imported from South Korea. The breathability of leather boots is very poor, coupled with the cold winter, the feet are constantly sweating, and the moisture formed by sweat evaporation cannot be discharged, resulting in very damp boots. The Qi army continued to urge the soldiers to advance, and many soldiers were too tired to change their socks, resulting in a large number of concentrated outbreaks of trench disease.

For a while, the Qi army slept at night and the stench was terrible. But a lot of soldiers have adapted to the smell. They also had to adapt. This is still the beginning, and beriberi caused by trench disease is not a big problem.

The problem is the fermentation of time. As the trench disease expanded, some of the soldiers' feet began to show some ulcers. This made the overwhelmed Qi soldiers slow down slowly. The speed of the Qi army slowed down.

Coupled with the fact that more and more sick people appear in the Qi army, the number of military doctors in the Qi army is not very large. There are very few soldiers who even know some medical knowledge. On average, there were only 2.5 doctors for every 2,000 soldiers in the Qi army.
