Just as the Manchu Qing spread his intelligence network throughout the country through trade, the Model Army also arranged its own spy network through trade. There were two routes to this network, one was to infiltrate the Manchu-controlled areas through Korea, and after Zheng Zhilong was named the king of Anpyeong, the "Dutch" occupying Jeju Island also threw off their own painting skin and directly played the banner of the Ming army. Speaking of Korea, between the Ming Dynasty and the Manchu Qing Dynasty, emotionally, it is actually obvious that it is more inclined to the Ming Dynasty. After discovering that the Ming army seemed to have regained the upper hand, the minds of many Koreans became active again. Some Koreans even came to Jeju Island in disguised boats and begged the Daemyeong soldiers to help them expel the Tartars. Although Zheng Sen did not agree immediately, secret contacts with the Korean government were established, and the route of collecting information about the Manchus through trade between Korea and the Manchus and through the Korean missions gradually opened up. The other is through Mongolia. After the fall of Li Zicheng, Wu Sangui collected a large number of Shun troops, and his strength swelled a lot, and then he turned to the north and began to raid and plunder the Mongol tribes non-stop, and at this time the Manchus not only could not support the Mongols, but even had to mobilize troops from Mongolia to deal with the model army. So the Mongols, who had always been grassy on the wall, immediately began to hook up with Wu Sangui. In this way, through them, Zheng Sen can also learn about some Manchu movements.

Although the scale of this intelligence network was not large enough, and there were not many things that could be accessed, the Manchus carried out large-scale mobilization, and such things could not be hidden from them. Therefore, when the Manchus were still mobilizing, the staff of the Model Army had already made a judgment: the Manchus might launch a large-scale attack on Niuzhuang Fort. In response to this information, the Model Army has also made full preparations. Zheng Sen personally came to Niuzhuang Fort to supervise the battle, (Zheng Zhilong was not very worried about this, so he gave Zheng Sen and the people around him an order: once there is ice floe in the port, let Zheng Sen retreat to Jeju Island immediately.) His younger brothers, Zheng Eun and Zheng Xi, were also brought to see the world. Gan Hui, Yu Xin, Zhang Ying, Chen Peng, and Wan Li each led troops to garrison a small fort, while Zheng Sen was responsible for the overall dispatch at Niuzhuang Fort.

At this time, the Qing army had already approached the first section of the earthen wall, and in many places even rushed to the earthen wall, and started a white-knuckle battle with the model army. Zheng Sen stood on the wall of Niuzhuang Fort, held a telescope to observe, and said to the herald next to him: "Implement Plan No. 1." ”

The herald nodded, and ran to the back, where the corresponding flag was raised on the flagpole behind him.

As the flag was raised, the Model Army began to retreat towards the second earthen wall.

"Keep up, don't let them get away!" Seeing that the Ming army was retreating, Aobai, who was leading the army to fight, shouted loudly.

Ao Bai knew that once the model army opened up the distance between them and them, the superior firepower of the model army would definitely deal a heavy blow to the Qing army, and only by biting them tightly and following them could they make it difficult for their firepower advantage to play and win the battle.

Like Aobai, the commanders of the other Qing army teams are also veterans of a hundred battles, and naturally they all understand this truth, under their supervision, the Qing army bites the retreating model army, and the two sides are almost wrapped together towards the second earthen wall.

The soldiers of the Model Army who ran in front were all soldiers, so the firing line of the Model Army on the second earthen wall was seriously disturbed. Although they tried their best to suppress the Qing army behind the retreating model army with firepower, the effect was not obvious.

In front of it is the barbed wire fence in front of the second earthen wall. Seeing that the retreating troops were approaching, several model army soldiers ran over and opened several gaps in the barbed wire, and the retreating model army quickly rushed through the gap.

Ao Bai gasped and ran as he threw his armor to the ground. Those Zheng Jiajun were too good at running, running faster than most Qing soldiers, and even faster than most of the white armor soldiers. Even if you worship yourself and don't get rid of the armor on your body, you can't keep up. Seeing that the enemy is about to escape the barbed wire, if they are pulled a little distance and let them close the barbed wire, will not all the work done is wasted?

Several white armors also followed Ao Bai and threw away their helmets and armor, but it is rare to say that those who chase after their opponents lose their helmets and abandon their armor. The group of model soldiers passed through the barbed wire, Ao Bai's eyes widened, and he rushed over with a loud shout, and those Zheng Jiajun seemed to be frightened by him, and they forgot to close the barbed wire, but turned around and ran directly.

"The enemy general is really a fool, how can he order a retreat at this time? He didn't know that retreating at this time could easily turn into a rout? At this time, as soon as you retreat, won't the army be defeated like a mountain? Is...... Fortunately, there are such enemy generals......" Ao Bai took the gap, then leaned to the side and gasped, watching more Qing soldiers follow through the gap, while thinking.

The Qing army followed the retreating model army and rushed to the second earthen wall, and the model army on the second earthen wall seemed to be disrupted by the "routed" own people, and after a little resistance, they also turned around and ran back. Even some artillery pieces were discarded. The Qing army easily took the second earthen wall.

Huang Taiji looked at the battlefield opposite from a distance, and in the smoke of gunfire, he saw that the military flags of the Qing Dynasty were rising one by one, and it seemed that they were making good progress, and the artillery fire of the Zheng family army on the opposite side was also much weaker. In the distance, a cavalry flying horse with a flag behind him was running here, and Huang Taiji knew that this must be to report on the battle.

"Report!" Before the cavalryman had even reached the bottom of the knoll, he had already shouted loudly, his face flushed, and he looked extremely excited.

Huang Taiji's personal guards recognized this man, this person was originally one of them, and this must have come to report the battle, so someone went over and took the horse and led the cavalry to Huang Taiji. When the cavalryman saw Huang Taiji, he knelt down on his knees, kowtowed and said, "Your Majesty, Ao Bai led people to break through the first earthen wall, and now he has taken the second earthen wall, and is advancing towards the third earthen wall. Commander Ao Bai asked the emperor to immediately invest in follow-up troops to expand and consolidate the results of the battle. ”

"Good! Good! Good! Huang Taiji excitedly hammered his right fist in the palm of his left hand and said, "What a worship!" That's a good job! ”

At this time, another cavalry came to report the victory, but it was with a white flag, saying that Sukh Saha had also broken through the second section of the earthen wall with his men and was pursuing the victory.

"Starling, let me take the children to follow!" As soon as he saw that there was something to be taken advantage of, Dorgon immediately stepped forward.

"Huang Ama, let me go too!" Hauge also stepped forward.

Huang Taiji glanced at them and said, "Okay, Old Fourteen, you bring the soldiers and horses from the headquarters, and I will give you four more Niu Lu's Wuzhen Chaoha, their muskets are also somewhat useful." After you enter, if the situation is good, take advantage of the victory and pursue it, and take some more points, and if the attack is weak, you must hold the place where you have already taken. Do you understand? ”

"Brother Chen understands, please rest assured!" Dorgon replied loudly.

"Hauge." Huang Taiji said again.

"Erchen is here!" Hauge clenched his hands into fists and half-knelt down.

"Go to the artillerymen at once, and let them drag the cannon to the earthen wall at once! Support our sons with artillery fire. Huang Taiji said.

Haoge glanced up at Huang Taiji, who seemed a little unwilling to do such a thing, but he finally replied, "Erchen obeys." ”

After saying that, he saluted Huang Taiji, turned around and went down the mountain. After a while, Dolgon was seen rushing into the battlefield with a large group of Qing troops.

At this time, Ao Bai led the Qing army to successfully cross the third earthen wall in the pursuit, and the situation was so smooth that Ao Bai felt a little scared. But at this time, he could only bite the bullet and continue to catch up.

There was a fourth earthen wall in front of them, and the Zheng soldiers who had fled ran faster, and some longitudinal trenches suddenly appeared in front of them. Without hesitation, the soldiers of the Zheng family army jumped into those trenches and continued to retreat from the trenches, almost in the blink of an eye, only the soldiers of the Qing army were left on the ground.

"Trouble, enemy artillery!" Ao Bai understood almost instantly, and he hurried forward a few steps, and jumped into the trench at once. The moment Ao Bai jumped into the trench, a cannon sound sounded in his ears. Yes, a cannon sound, so dense that you can barely tell the distance between one cannon and another. Shotguns and shrapnel swept across the land like a storm, and after the cannon fire was over, Ao Bai poked his head out of the trench and saw the corpses of the Qing soldiers lying behind him.

"Damn, there's an ambush!" Ao Bai thought. It's just that he couldn't understand how the opponent planned to ambush for a while.

The model army had withdrawn behind the Fourth Earthen Wall. Ao Bai stayed alone in this trench, following his Qing army, and after suffering this heavy blow, he almost died, and the Qing army farther away had not yet followed.

"What are they doing? Even if the fourth earthen wall is defended, at least the first three earthen walls have fallen into our hands? Ao Bai thought about it and felt that even if these people he brought with him suffered a big loss here, on the whole, this wave was not a loss. It's just that I'm stuck here, and it's really a question of how to get back.

Ao Bai was thinking about how he could cross the distance of nearly 100 meters and return to his team, when he heard a panicked exclamation from the side he had just occupied, and the sound was so loud that it was like a flood had burst. Immediately after that, Ao Bai saw billowing black smoke rising from that side. This black smoke does not rise from one place or two, but everywhere!
