Outside Dalinghe City, the Later Jin army dug four trenches around Dalinghe City and built a wall more than one meter high, surrounding Dalinghe City like an iron barrel.

However, because of Li Guodong's trick, the time of the Later Jin army in the pass was delayed later. In history, the Later Jin army began to siege the city on August 6th, and delayed for more than a month. In this time and space, it became September 10th, and Zu Dashou was besieged for more than a month. The reason why Zu Dashou was besieged for more than a month was delayed for more than a month than in history was that the time of the Later Jin army's exit from the pass was delayed for more than a month. The result was that Zu Dashou's construction of Dalinghe City was delayed for more than a month, which caused a chain reaction. The plan for siege of the Later Jin army was delayed for more than a month.

Another historical change brought by Li Guodong was that Sun Chengzong improved the chariot camp and built a snow car camp, equipped with three-pound field cannons and the Folang machine cannon with improved sub-guns.

The three-pound field cannon can easily penetrate the shield car of the Later Jin army, and the Folang machine cannon equipped with an iron-core copper-shelled gun can penetrate the shield car of the Later Jin army.

In fact, because copper is far more ductile than iron, a large part of the iron core and copper cannon has solved the problem of air leakage in the powder gas of the Folang machine cannon, greatly improving the range, power and accuracy.

The Daling River lunar month has become very cold since September, especially in the late autumn of the Little Ice Age.

When Sun Chengzong learned of the news of the besiege of Dalinghe City, he did not immediately send troops to rescue him, but waited for the snowfall to come.

"Why don't the supervisor send troops to rescue Dalinghe?" asked General Wu Xiang.

Wu Xiang's second son was only nineteen years old and was already the best in the three armies. This second son was Wu Sangui.

Sun Chengzong smiled without saying a word and did not answer directly. He knew that the old side vans and main vans were far less powerful than the new snowmobile. The snowmobile ran at a speed that was not inferior to the war horses, and its firepower was fierce. Moreover, even if the snowmobile was defeated, he was not afraid of being chased from behind, because the snowmobile could shoot arrows backwards while running, which did not affect the speed of escape. This weapon was simply the most suitable weapon for the Ming army, who often ran away.

In fact, Li Guodong didn't ask that when the Ming army was chased, he could turn around and kill many Later Jin troops with bird guns and bows. It would be good to kill a few Mongols with low quality bird guns and bows. Jurchen soldiers could not even shoot through armor. Once the Jurchen soldiers approached the hand-to-hand combat, the garbage soldiers of the Ming army who had almost lost their hand-to-hand combat capabilities would have no power to fight at all.

The biggest function of the snow bike camp is to deal with Mongolian cavalry. It is a very good weapon to restrain the Korqin Mongolian cavalry. When the Ming army retreated, the Later Jin heavy cavalry chased slowly and could not catch up with the Snow Bicycle camp at all. In the pursuit of the Later Jin Dynasty, the Ming army liked to chase Mongolian light cavalry, and the Snow Bicycle camp could play a role at this time.

The Later Jin army suffered losses because of attacking the solid city, so they did not attack Dalinghe City. Instead, they adopted the method of siege, surrounded the points and attacked the aid, while besieging Dalinghe City, forcing Zu Dashou to surrender, and at the same time deceived the Ming army into going out for field battles.

Starting from the end of September, heavy snow fell outside the pass, and the earth quickly covered with thick snow.

Seeing the ground covered with snow, Sun Chengzong ordered the chariot camp to dispatch to reinforce the besieged Dalinghe City.

The reinforcements of the Ming army were led by Wu Xiang and Song Wei, with a team of 6,000 troops, equipped with 250 chariots, and also equipped with 3,000 cavalrymen.

After a thousand miles of freezing, Wu Xiang and Song Wei took the car camp to the Daling River to rescue Zu Dashou.

Like in history, when Wu Xiang saw the Later Jin army erected the Red Barbarian cannons, he immediately ordered to turn around and retreat.

The Later Jin army pursued the Mongolian cavalry, and thought that as usual, the pursuit of the Ming army would cause heavy losses to the Ming army, but the pursuers did not suffer any losses at all. However, this time the Mongolians suffered a great loss. The retreating camp shot arrows and projectiles from time to time, constantly knocking down the Mongolian cavalry who were chasing themselves. As a result, the pursuiters did not hurt a single hair of the Ming army, but were shot and killed more than a thousand people.

When Huang Taiji saw that the Mongols of Korqin suffered a great loss, he immediately ordered the Mongols to give up their pursuit.

"Snowmobile Camp!" Huang Taiji said with a slight smile, "When the Snowmobile Camp is defeated again, you must not pursue it! To deal with this object, you can only set up an ambush halfway to break it with heavy infantry!"

Huang Taiji had already come up with a way to deal with the Che Battalion. When he saw the Che Battalion coming, he used the red barbarian cannons to repel the Ming military Vestation Camp, and then let the Mongolian cavalry follow him from afar, but don't chase him. At the same time, he ambushed heavy infantry on the retreat road of the Ming military Vestation Camp and dig traps. As long as the Che Battalion stops, the elite heavy infantry of the Later Jin Juzhen can enter the Che Battalion and kill the Ming army.

On October 2, Wu Xiang and Song Wei brought more than 10,000 Ming troops, two snowmobile battalions and five thousand cavalrymen to reinforce again. As a result, they were bombarded by the Red Barbarian cannons of the Later Jin army, and more than ten snowmobile cars were destroyed.

Of course, what Wu Xiang had to do was to turn around and run away, and the car camp retreated back again.

This time, the Mongolian light cavalry did not chase and chase, but followed him from a distance and did not enter the range of the chariot camp at all.

On the way to retreat, the car camp was ambushed by the Eight Banners Army of the Later Jin Jurchens. More than a dozen snowmobile in front fell into the trap, causing the snowmobile behind to hit and collided with each other. The cars and cars were blocked and squeezed each other.

The Eight Banners of the Later Jin Dynasty immediately launched an attack, and countless Later Jin infantry wearing armor of various colors and wearing a white cloak jumped out of the snow and rushed towards the chariot camp.

The Ming army could no longer run away, so they had to bite the bullet and fight.

The Fran machine cannon, three-pound field cannon, tiger squat cannon and other cannons spewed out flames, overturning the attacking Later Jin army a lot. When the Later Jin army approached, the Ming army's bird guns, nine-headed birds and bows and arrows shot volleys, and swept countless Later Jin army.

However, Huang Taiji was not worried. Almost all the Later Jin Jurchen soldiers who were beaten to death in front were coated cannon fodder teams.

After the cannon fodder in front consumed the Ming army's ammunition, the elite heavy infantry of the Later Jin rushed up. After being approached by the Later Jin army, the Ming army immediately collapsed. Except for a few servants who could fight in close combat, the rest of the Ming army did not dare to fight in close combat, and they gave up the car formation and fled.

Wu Xiang and Song Wei could not resist it, so they led their servants to break through the siege and fled back to Jinzhou. More than 10,000 Ming troops were killed more than 3,000 people, and the rest surrendered.

"These artillery is indeed extremely sharp! Kill us more than 2,000 Ah Ha! The armored men also lost more than 200, and the elite Jurchen warriors also lost more than 50 people. It's a pity that the Ming people are not good at melee combat, otherwise our army would really not be able to break the formation of the chariot." Huang Taiji sighed at the seized four three-pound field cannons and one hundred improved versions of the Flang machine cannons.

Fan Wencheng brought a group of Han craftsmen to check the captured cannons. After the craftsmen saw the cannons, they praised them endlessly.

"Can you imitate such a weapon?" Huang Taiji asked.

Fan Wencheng said, "When you sweat, your servant will definitely live up to the high expectations of the sweat!"
