During the stalemate, Qu Neng, the governor of the Ming Dynasty, took the lead, and with the help of his two sons, he led more than 1,000 elite cavalry soldiers to take advantage of the chaos to enter Zhangye Gate in Beiping, which was unstoppable.

After attacking the city gate, the Yan soldiers rushed to fight, Qu Neng and his son resisted on the one hand, and sent people to quickly report to Li Jinglong to send reinforcements. Li Jinglong was jealous of Qu Neng's bravery, and was afraid that he would seize the lead in attacking Yan, so not only did he not send people to support, but instead sent messengers to stop Qu Neng and let them exit the city gate, saying that they would attack the city together when the Ming army arrived.

"Don't miss the opportunity, you won't miss it. "Yan Bing poured water on the city wall overnight, the sky was cold and frozen, and the next morning the entire Beiping City became a hard and smooth ice wall, and Ren Mingjun couldn't climb it no matter how great his ability was.

The defenders of Beiping bought precious time, and Zhu Di, the king of Yan, returned to the army very smoothly on the road. Zhu Di also took a short rest in Huizhou, briefly read the soldiers, divided the army into five armies, each led by Zheng He, Zhu Neng and other brave generals, and incorporated the Mongolian cavalry attached to Daning into each army.

In December, the Yan soldiers led by Zhu Di took advantage of the freezing of the North River, and suddenly launched an attack on Chen Hui, the vanguard governor of the Ming Dynasty, and defeated the Ming army. The Yan soldiers took advantage of the victory to pursue, and the strange soldiers attacked left and right, breaking the seven battalions of the Ming army in a row, and approaching Li Jinglong's Chinese army camp. Zheng He and others deployed military horses, lined up to force the front, and forced the Ming army to retreat.

The Ming army had just retreated to the city, and the city gate in Beiping City was wide open, and the Yan soldiers shouted to kill from the inside, and the two sides attacked. Li Jinglong's Ming army could no longer support it, and he himself abandoned the camp and fled overnight. The next morning, the Ming army, which was holding the Nine Gate Fort, resisted hard, but was still broken through the fourth base by the Yan soldiers. In a panic, everyone heard that the coach Li Jinglong did not know where to go, and suddenly the stars scattered, discarded the military rations, and ran south in the morning and night. Like a rabbit, Li Jinglong fled all the way to Texas.

Emperor Jianwen vaguely heard that the war was unfavorable, so he asked Huang Zicheng how it was going, because Li Jinglong was highly recommended by himself, Huang Zicheng concealed the defeat and did not report, and replied: "I heard that our army has won several battles, but the weather is extremely cold, and the soldiers can't bear it, so now I will temporarily return to Texas and wait for next spring to attack again." At the same time, Huang Zicheng sent someone to report to Li Jinglong urgently, not to report the defeat.

Emperor Jianwen didn't know about it, so he sent his subordinates to add Li Jinglong as the prince and teacher, and gave him a seal book, gold coins, imperial wine, and mink qiu. Li Jinglong convened and integrated the Ming army from all walks of life in Dezhou, and Zhu Di, the king of Yan, was not idle, he gathered the generals and said.

"Li Jinglong is resting in Texas, and he definitely wants to wait for next spring to attack in a big way, and what he needs to do now is to lure out the Southern Army so that they have no time to rest. Therefore, I want to personally lead the army to attack Datong, Datong is in an emergency, and Li Jinglong will definitely send troops to the rescue. The southern soldiers were physically fragile, marching back and forth in the bitter cold and icy north in winter, exhausted from running for their lives, and would flee a lot because of cold and hunger. Drag it out until next spring, and then we will break the main force of the imperial court according to the situation. ”

After several fierce battles, he had already seen King Yan's strategy, and none of the Yan generals expressed any objections, and they all expressed complete agreement. So the Yan soldiers, under the leadership of Zhu Di, went straight out of the Bauhinia Pass and conquered Guangchang.

In the second year of Jianwen, Zhu Di, the king of Yan, besieged Ulzhou again, and soon the Ming army surrendered. The Yan soldiers were bloodless and went straight to Datong, with great momentum. When Li Jinglong heard the news, he hurriedly led the army to rescue Datong, the Ming army came in from the Bauhinia Pass, and Zhu Di had already returned from Juyong Pass, returned to Beiping, went around in a big circle, and returned to the city in victory.

During this period, the most bitter thing was that tens of thousands of soldiers under the leadership of Li Jinglong died of hunger and freezing along the way, and two or three out of ten of the soldiers in the army had their fingers frozen, and their combat effectiveness was greatly reduced. The Ming army discarded its armor along the way, and the loss of weapons could not be calculated, so the plan to attack Yan in the spring was not implemented.

Li Jinglong will join the troops in Dezhou, and the Ming army will wait for Guo Ying, An Lu and Wu Jie will also lead troops to Zhending. Li Jinglong led his troops across the river, and the forward general had already reached the Baigou River in advance. Guo Ying and others passed through Baoding and agreed to meet Li Jinglong at the Baigou River and march together. Soon several Ming armies converged, with a total of 600,000 soldiers, known as one million male soldiers, stationed in the Baigou River, lined up in a large array, and prepared to fight with the Yan soldiers.

In the face of the menacing and prepared Southern Army this time, Zhu Di, the king of Yan, was still unfazed: "Li Jinglong, a puppet, relies on his many people, but the number of people cannot be relied on. It is easy to be chaotic when there are many people, do not know when attacking the front, do not respond to the attack on the left and the right, do not specialize in the generals, have different government orders, and the food and salary of the first soldier can be used as the capital of our army. So Zhu Di sent Zheng He to Baigou first, and he followed.

In this match, there is indeed no shortage of heroic talents in the Ming army, and the forward general Ping'an used to be the general of Zhu Di, the king of Yan, and many times followed the king of Yan out of the fortress to attack the cavalry of Mengyuan, and knew Zhu Di's way of using troops.

The two armies faced each other, Ping An immediately led more than 10,000 elite cavalry to kill the Yan army, Ping An himself was tall and strong, brave and good at fighting, holding a sharp spear, prancing into the battle, and a person rushed to the front of the Ming army. Qu Neng's father and son also then leaped forward, invincible, killing and injuring many Yan soldiers. After a wave of impact, the Yan army suffered a lot of damage and suffered a small defeat.

At the critical juncture, the Yan general Gu Yun and a eunuch named Gou'er were very brave and led two Yan troops to hedge against the southern soldiers. Zhu Di himself personally led his troops to attack, and the two sides fought in a melee, and the battle lasted until dark, and the two sides each withdrew their troops. In this encounter, the Yan army lost a lot, and the Ming army of the Ping An Forward only lost more than 100 war horses.

Because the Ming army planted a lot of land mines in the ground, the Yan soldiers were killed and injured a lot. When the two sides rested late at night, Zhu Di, the king of Yan, only led the three cavalry palaces, got lost halfway, and finally lay on the ground for a long time, found the riverbank, and then distinguished the east, west, north and south, and stumbled back to the camp.

After returning to the camp, Zhu Di ordered Zheng He to lead the Chinese army, Zhu Neng to lead the left army, and Chen Heng to lead the right army, gathering more than 100,000 soldiers of all the horse infantry army, and at dawn they lined up with the Ming army. The Ming general Qu Neng was eager to win, and led his subordinates to sweep the Yan general Fang Kuan's army array, and the Ming forward general Ping'an was also covering beside him, breaking through the Fang Kuan array and capturing hundreds of Yan soldiers.

Zheng He and other Yan generals saw the defeat of Fang Kuan's army, and they were all afraid, Zhu Di was unmoved, and encouraged: "Victory or defeat is a common thing in soldiers, although they have many soldiers, but in the middle of the day, I promise to defeat them for the kings." After speaking, Zhu Di personally led thousands of elite cavalry to break into the Ming army's large array, and Zheng He and Zhu Di's son Zhu Gaoxu marched together.

The Ming army and the Yan soldiers raised their guns and wielded their swords, and the horse soldiers and infantry fought together, and the two sides fought for more than 100 rounds, with heavy casualties. Zhu Di rode a lot of horses, and he changed horses three times, and the arrows he carried around him also shot out three times. In the end, the king of Yan could only fight with his sword, and finally fought until the blade of the sword was broken, and the horse he was riding tripped over the river embankment, and was almost stabbed to death by the Ming general Qu Neng. In a panic, Zhu Di fled to the high place of the embankment, waved his whip to beckon to the embankment, and pretended that there were his own ambush men and horses below.

Li Jinglong saw it from a distance, for fear of being ambushed, and hurriedly ordered the Ming army to retreat. Zhu Di changed to a new horse, and then led his troops to turn around and rush into the formation to kill.

The Ming general Ping'an was strong in martial arts, and he attacked back and forth in the formation, specially selecting the generals of the Yan army to cut and kill. It didn't take long for Ping'an to behead Yan and Chen Heng, and cut off several fingers of Yan and Xu Zhong. Seeing that the situation was critical, Zhu Gaoxu hurriedly led thousands of elite cavalry soldiers to rush into the formation, killing and intertwining with the Ming army. At this time, Zhu Di himself was extremely tired, but he couldn't hold on with his willpower.

The battle lasted until noon, and the Ming general Qu Neng led the defenders to charge the battle again, shouting: "Kill Yan!" and kill hundreds of Yan soldiers. At the critical moment, suddenly a gust of wind blew, and the most conspicuous division flag in the Ming army was suddenly blown off. Seeing this, Zhu Di commanded the cavalry to break into the Ming army formation from the flank, galloped and slashed, and joined forces with Zhu Gaoxu, and in the chaos, he actually killed Qu Neng's father and son, who had been exhausted in battle. The Ming general Ping'an and Zhu Neng were also defeated, and they went back, so the Ming army collapsed, and the sound of running and fleeing was like thunder.

The Yan army took advantage of the wind and set fire to the Ming army camp, and seeing that the general trend had gone, Li Jinglong and others fled for their lives, and more than 100,000 people were killed and drowned in the river. The Yan army pursued all the way to the old battlefield Yuexiang Bridge, and the Ming army was killed and drowned tens of thousands of people, and the corpses were more than 100 miles away. The Ming armies collapsed, and only the army of Xu Huizu, the Duke of Wei, was the only one.

Li Jinglong ran to Texas before he could catch his breath, and the Yan soldiers had already caught up, so he ran to Jinan again, and Texas finally fell into the hands of the Yan army.

Fortunately, it was Tie Xuan, a loyal minister of Emperor Jianwen, who was holding Jinan, and the Yan army's soldiers stopped abruptly. Tie Xuan was originally a political participant in Shandong, responsible for urging the overseer to pay for Li Jinglong's army to do logistics support work, he heard the news of the defeat of the Ming army, Tie Xuan collected the defeated Ming soldiers, defended Jinan, and let more than 100,000 Yan soldiers who had just won the victory take turns to charge, standing still.

When Emperor Jianwen heard the news, he immediately promoted Tiexuan to be the political envoy of Shandong, and recruited Li Jinglong, the army of the defeated army, and then issued an edict with Sheng Yong as the general and Chen Hui as the deputy general.

Li Jinglong fought two wars and lost millions of soldiers of the Ming army, because he had a close relationship with the Zhu Ming royal family, Emperor Jianwen pardoned him but did not kill him. The sponsor Huang Zichun regretted and was anxious, and cried bitterly: "Li Jinglong went out to wait and see, with two intentions, if he didn't kill him, how could he apologize to the sect and encourage the soldiers?"

Lian Zining, the deputy capital of the imperial capital, also caught Li Jinglong at the court meeting, counted his crimes, and begged Emperor Jianwen to kill this half-hearted and war-spirited old playboy, but after all, it was his cousin, and Emperor Jianwen did not agree.

After the Yan King Zhu Di's army of more than 100,000 people, he surrounded the city of Jinan for more than three months, and he could not even attack it, and after all kinds of tactics failed, the Yan army began to block the water sources of various streams and rivers outside the city, preparing to irrigate the city with water, and the defenders and people in the city of Jinan were greatly frightened. Tie Xuan said calmly: "Don't be afraid, I have a plan to break the thief, and within three days, the thief will flee." ”

Tie Xuan arranged a deception plan, he sent a strong man to install a large iron plate at the top of the arch of the city gate, and made the city guards cry and wail: "Jinan City is about to be flooded, we are going to die!"

Soon, he withdrew the defense line of the building, and sent the elders of the people in the city to replace the defenders as messengers, and went to the camp of King Yan to kneel and ask for surrender: "There are traitors in the court, so that the king you risk the danger of life and death." You are the son of Emperor Gaozu, we are all subjects of Emperor Gaozu, and we have always wanted to surrender to you, the king. But we Jinan people are not accustomed to soldiers and horses, and when we see the army pressing the border, we are afraid of being killed by the sergeants. Please retreat ten miles from the king, ride into the city alone, and we will welcome you. ”

Yan Wang Zhu Di didn't know that it was a ploy, and he was overjoyed when he heard about it. After a few days of marching, the Yan soldiers were extremely tired, and if Jinan City surrendered, it would be able to cut off the north and south and occupy the entire Central Plains. Therefore, Zhu Di was busy ordering the sergeants to move the camp and retreat, riding a horse by himself, with a large Huangluo umbrella, with only a few guards, crossing the moat bridge, and entering the city to prepare for surrender.

The city gate was wide open, and the Ming army defending the city gathered on the city wall to watch. As soon as Zhu Di, the king of Yan, entered the city gate, all the soldiers shouted: "Chitose is here!"

The big iron that was placed on the door arch in advance fell suddenly, but fortunately, Zhu Di's life was big, and the iron plate fell a few tenths of a second earlier, and it hit the head of the horse that King Yan was riding. King Yan rolled to the ground, frightened, and the guards around him were busy changing him into a new horse, and the group turned their horses and ran out. The Jinan guards hurriedly pulled the moat pontoon, but unfortunately the bridge was heavy for a long time, and it took a lot of effort to pull up a height of more than one meter, and Zhu Di and a group of guards galloped away.

In a fit of rage, Zhu Di waved his troops to attack the city, Tie Xuan lay down at the head of the city, scolding Zhu Di for being a thief, and King Yan was furious and brought several artillery pieces to bombard the city. At the critical juncture, Tie Xuan personally wrote down the god card of Emperor Zhu Yuanzhang of Gaozu and hung it above the four cities. Seeing that there was Zhu Yuanzhang's magic card, the Yan soldiers did not dare to use artillery again, and Jinan City was saved.

Between the standoffs, Tie Xuan often took him by surprise, sending brave soldiers to rush out of the city day and night, harassing and attacking the Yan soldiers, making this group of tired soldiers helpless, and many of them were killed and wounded. Zhu Di was very angry, but there was no way to do it, and the monk Daoyan persuaded him that the Yan soldiers were tired and should return to Beiping to try to do it later. Zhu Di listened to the persuasion and returned to Beiping.

Tie Xuan and Ming general Sheng Yong and others took advantage of the victory to pursue and recover Dezhou and other places, and the army was greatly boosted. Emperor Jianwen issued an edict to promote Tie Xuan to be the secretary of the military department to assist Sheng Yong in preparing for the Northern Expedition to the Yan Army.
