After Gao Yiming, who was in Nanjing, received the news of the fierce battle between the main force of the Qing army and the grassland coalition army, he immediately ordered Li Dingguo to lead the Ming army to the north, and concentrated the only fifteen 107-mm rocket launchers and twenty Gatlings to him, so that he could take the opportunity to capture Daning, Guangningwei and Guangning Zhong, Zuotunwei, and restore the Guanning defense line. At the same time, he ordered Huang Degong to make a feint and threaten the rear of the main force of the Qing army.

After receiving the order, Li Dingguo immediately led an army of 200,000 to set out, and the navy, which already had 60,000 horses, was also dispatched at the same time to support them by sea.

The Ming army in Shanhaiguan was based on the Guanning army, and many people were eager to return to their hometowns, so as soon as they arrived on the battlefield, their combat power soared, coupled with the boat's sharp artillery, and they quickly took these three cities.

The Qing army had to expedition to the grassland before, so it withdrew 100,000 horses from Daning, and the defenders were only 10,000 or 20,000.

Dolgon, who was in Shengjing, was shocked when he heard that the Ming army had recaptured the three important towns of Guanning, and immediately mobilized the people in the country to prepare for a decisive battle with the Ming army in Shengjing.

Unexpectedly, after the Ming army took these three cities, they actually defended on the spot and did not continue to advance north. Unable to figure out the routine of the Ming army, Dolgon approached Hong Chengchou to discuss.

After analyzing the offensive lines of the two Ming armies, Hong Chengchou came to the conclusion: "Lord Wang, it seems that the Ming army is not ready for a decisive battle with me."

"How so?"

"You see, after Li Dingguo occupied Daning and other three cities along the way, he immediately strengthened the city wall and stagnated, and the Ming army Huang Degong, who had set out from Wanquan Dusi, also returned the same way soon after entering the grassland, so it can be seen that the Ming army only wanted to take advantage of the main force of our army to fight with the grassland departments, and take the opportunity to restore the Guanning defense line."

"The Ming Army's Guanning Defense Line was taken down by two generations of us, and now it is easy to lose, what should I do."

"Lord Wang, please rest assured, Shengjing, the core of the Guanning defense line, is still in our hands, and there is nothing else to worry about, I suggest that the cities between us and Daning be destroyed immediately."

"Are you sure?" Dolgon looked at Hong Chengchou in surprise.

"Sure! The Ming army defending the city is the strength of the Ming army, and our strength is the cavalry rush, as long as those unseen cities are destroyed, then Shengjing and Daning will basically be a horse and a flat river, so as long as the Ming army dares to invade the north, our cavalry can immediately surround the Ming army on the grassland and eliminate it. ”

"What you said is good, after the destruction of the city, what will happen to the people in the city?"

"It's easy to do, we all moved to Shengjing, Shengjing is our capital, and the population of hundreds of thousands is less."

"What if they don't want to?"

"That's better, just kill a few people who take the lead in making trouble."

"Haha! Mr. Hong really deserves to be a cadre who shares worries for the country, good! That's it, you take care of it yourself. Dolgon smiled and couldn't help but curse in his heart: "Ruthless!"

Gao Yiming, who was in Nanjing, learned from the mouths of the exiles what Dolgon had done, and was shocked, if this thing was done, then the Qing army could give full play to the advantages of their cavalry, and the Qing army, which had no worries, could attack the Ming Dynasty from any point on the border line at any time, and could not defend it by relying on infantry alone, and could not hold it, and it was necessary to train a strong Ming cavalry, for this reason, the Qing army must not be allowed to occupy the grassland.

So Gao Yiming ordered Huang Degong and Gao Jie to reduce the only 50,000 or 60,000 cavalry in their hands to 30,000 people, reaching two horsemen per person, led by Zhang Huangyan, and constantly attacking and disturbing the rear of the Qing army.

Although it is not a long-term method, there is only this he can do at present, and the survival of the various tribes of the grassland still depends on whether their warriors are brave or not.

Gao Yiming also knew that once the Qing army got out of the war with the grassland coalition army, then the Ming army in Daning and other places was likely to be eaten by the Qing army, but in order to re-establish the Guanning defense line and grasp the initiative in the decisive battle with the Qing army in the future, he had to race against time again, he was ready to create another battlefield artifact infantry chariot, of course, it was not like that of later generations, the current iron smelting technology of the Ming Dynasty did not allow it, and he was ready to transform the tractor. For this reason, he ordered the construction of three more arsenals, because he also figured it out, the war horse could not be cultivated for a while, and it was impossible to buy it to meet the combat needs of the Ming army, so he was ready to continue to build new weapons to offset the cavalry advantage of the Qing army.

As early as the end of spring ploughing, he ordered the arsenal to collect the two tractors that had been put into use, plus the three new ones that were built later, a total of five, he ordered the arsenal to add a pyramid-shaped iron shell to the outside of the tractor, and set up a shooting tower at the top, leaving a lookout, which was also sealed with an inch thick glass, in order to prevent enemy archers. At the same time, the coal hopper was enlarged, the fuel self-load was increased, and each car was equipped with eight fighters, a driver, a coal miner, three Gatling gunners, and three ammunition men.

Because it is a new process, the speed of modification is very slow, from April to October, it can be completed, after the completion of the modification of the five chariots, transported to the hands of Li Dingguo in Daning, it is already the season of snow outside the Guan.

Looking at the five steel beasts in front of him, it really scared the defenders a lot, who could have imagined that the iron bumps like a hill would actually move by themselves with black smoke, although the speed could be thirty kilometers an hour, which was not fast.

But Li Dingguo fell in love with this thing after trying it, Wutai this thing, plus the 60,000 cavalry in his hands, he had the confidence to fight with the 100,000 elite cavalry of the Qing army.

Because Gao Yiming on each infantry chariot was equipped with three Gatlings, and three spare, each with 10,000 rounds of ammunition, at this time, the high horsepower of the steam engine came in handy, and it was changed to a gasoline engine to kill without such a large load capacity, and the vehicle weighed more than 30 tons. In order to withstand such a large weight, each car was equipped with eight wheels.

From a distance, although the shape is a little strange, the firepower is really fierce, like a fortress of action.

At this time, the main force of the Qing army was still planning a fierce battle between the city and the grassland coalition army.

Daishan's Chinese army tent, Haoge, Duoze, Aobai, etc. are all there.

Dai Shan said: "Now we have been fighting with the coalition forces of the grassland departments here for almost eight months, and some people are already sleepy and tired, thanks to the fact that we are not supplied from the rear, otherwise coupled with the chaos of the Ming army, I am afraid that we will have to withdraw our troops long ago." ”

"Humph! At the beginning, I said that I should take the Ming Dynasty in one go, but he Dolgon just didn't listen, what is happening now? I almost lost Sheng Kyoto. Hauge slammed the glass in his hand and said angrily.

"What are you doing so magnificently, you're the craziest here, haven't killed enough? The Ming army does not have the strength to attack Shengjing, and we will go back and get back the lost three cities, and the Ming army of the three cities is our bag, and the little emperor Chongzhen still can't change his dog to eat, and he loves to take advantage of it. ”

Dai Shan's words caused everyone in the tent to laugh, and Hauge also laughed.

"I came to you today to discuss the war in front of us."
