At the beginning of March, an inevitable thing happened that worried Li Yuntian, when the Mongolian army of Yinzhou City sent an envoy to Kaiyuan City to persuade him to surrender, he trumpeted that Emperor Xuande was defeated by the army led by Arutai at the Yuma River, which caused a lot of waves in Kaiyuan City.

Originally, the people of Kaiyuan City did not believe the words of the Mongolian envoy and thought that it was nonsense, but to the surprise of the soldiers and civilians, several people wearing Ming army uniforms appeared in the team of persuading the envoy to surrender, and two of them were also wearing eunuch clothes.

In particular, the two people wearing eunuch costumes actually took off their pants in public to prove that they were the chamberlains in the palace, which caused a lot of impact on the soldiers and civilians of Kaiyuan City.

According to the envoy of the Mongolian army, Arutai completely annihilated Emperor Xuande's 200,000 troops on the Northern Expedition at the Yinma River, and Emperor Xuande led thousands of remnants of the defeated army to flee back to Datong City.

Not only that, Arutai had already gathered 300,000 heavy troops to attack the Daming Xixing Capital Division in February, and in the face of the overwhelming pressure of the Mongol army, the Datong City of the Shanxi Xingdu Division, was just around the corner.

Li Yuntian did not care about the Mongolian envoy's claim that Arutai led an army of 300,000 to invade the south, and if the Tatars and Warat had done their best, they would have been able to gather more than 300,000 horses, but the Liaodong battlefield had already dragged more than 100,000 Mongolian troops, so the troops led by Arutai would definitely not reach 300,000, and it was obvious that Arutai was bluffing.

However, there was a piece of bad news that worried Li Yuntian, and the Mongolian envoy who came this time proudly announced that the Ming army under the command of Alutai had captured the vanguard of Emperor Xuande's Northern Expedition, Xingping Hou Zhao Yong, and was on his way to Liaodong.

Li Yuntian knew very well in his heart that the Mongolian army must have brought Zhao Yong to Liaodong to persuade the Ming army in Liaodong to surrender, and there must have been other Ming prisoners of war.

Emperor Xuande's Northern Expedition was defeated in the Yinma River, and many Ming soldiers must have become prisoners of war of the Mongolian army, with these captured generals being escorted to Liaodong, the news of Emperor Xuande's defeat in the Northern Expedition will no longer be able to conceal it, and the morale of the Ming army that will stick to Liaoyang City and other important military towns will be hit hard, and the consequences will be unimaginable.

What is particularly important is that since the Ming army in Liaodong entered Xuande eight years ago, it was no longer able to obtain logistical supplies from the Beijing division, and Li Yuntian not only had to provide grain and grass for the 70,000 troops in Kaiyuan City, but also had to support the 50,000 Korean soldiers recruited in Pyongyang Prefecture in Xijing.

According to Li Yuntian's plan, 50,000 Korean soldiers recruited from the Korean Kingdom were to train in Pyongyang until the end of March of the eighth year of Xuandeok, and then rushed to Liaodong in early April to participate in the war.

In addition to these 120,000 troops, there is not much grain and grass left in the military towns in Liaodong that were firmly guarded by the Ming army, and they are now waiting for the arrival of reinforcements.

Li Yuntian calculated that if he purchased grain from the Korean Kingdom, plus the grain and grass he shipped from Tianjin Port, he could support the military rations of the 200,000 army until the end of the eighth year of Xuande.

If the Ming army in Liaodong is still unable to defeat the Ming army in Liaodong before the end of the eighth year of Xuande and open the Shanhai Pass blocked by the Mongolian Ulianghabu, then the Ming army in Liaodong will be attacked by a food shortage, and it is likely to collapse without a fight, after all, the Korean Kingdom does not have much food for the Ming army to procure, and the focus of the imperial court is focused on the war in Shanxi Xingdusi, where is there still the energy to pay attention to the war situation in Liaodong, and nine times out of ten it will let the Ming army in Liaodong withdraw to the Korean Kingdom.

The defeat of Emperor Xuande's northern expedition not only put Li Yuntian under tremendous logistical pressure, but also forced him to change the established style of fighting in Liaodong step by step, and then adopt the strategy of defending as an offensive to take the initiative to find fighters, in order to turn the tide of the war in Liaodong and reduce the military pressure on the Shanxi Xingdu Division.

Li Yuntian met with the envoys of the Mongol army in the reception hall of the Liaodong Zhuque camp of the Xiaowu army, and the generals of the Ming army and the leaders of the Jurchen tribes were all present.

The envoy of the Mongolian army told him that Emperor Xuande's army of the Northern Expedition had been annihilated, and the Mongolian army had already moved south under the leadership of Arutai, and the military towns of Shanxi Xingdu Division and Wanquan Capital Division such as Datong City and Xuanfu City were just around the corner, and the Ming Dynasty would be tired of dealing with Arutai's army at that time, and would have no time to take care of Liaodong.

"If you can scare the official by casually finding two eunuchs, Mansu and Mu Du are too underestimating the official." Looking at the high-flying envoy of the Mongolian army, Li Yuntian took out an official document and said with a sneer, "This official has just received a report from the imperial court, my eldest son led the army to level Hala and Lincheng in February, and will return to Beijing in the near future, how can I say that I am defeated?" As soon as my Great Ming Xiongshi arrives, you will wait to die! ”

"It seems that your court has deceived you, my Northern Yuan army killed your Ming army in the Yuqu River last year, and your emperor was chased by my brave cavalry and fled, and it is impossible to save you." Hearing this, the Mongolian envoy sneered with disdain on the corner of his mouth, and turned his head to look at the Ming army captives who were standing behind him in despair, "You tell him, did my Northern Yuan army completely annihilate your Ming army in the Yuqu River?" ”

The Mongolian envoy said that the Yuqu River is the Drinking Horse River, that is, the current Krulun River, located in the southeast of the Tatar city of Hulan Huxuan, the Yongle Emperor led the army to this point when the first northern expedition was renamed "Drinking Horse River", so the Ming Dynasty called it the Drinking Horse River, and the Mongols still called it the Yuqu River.

"Do you think the official will believe you?" Without waiting for the Ming prisoners of war to speak, Li Yuntian sneered, and said to the Mongolian envoy in a deep voice, "You go back and tell Sù Mansu and Mu Du, this kind of carving insect skill is useless to this official, this official will take Yinzhou City within three months, and then this official will have a drink with them in Yinzhou City!" ”

As he spoke, Li Yuntian got up and walked away, too lazy to talk to the envoy of the Mongolian army.

"Damn!" Seeing this, the generals of the Ming army and the leaders of the Jurchen tribes at the scene followed Li Yuntian out of the reception hall and hung the Mongolian envoy there, which made the face of the Mongolian envoy blue and white for a while, and spit out two words viciously in his mouth, he had never seen such an arrogant Ming army general, and he dared to speak out unashamedly to claim that he would take Yinzhou City within three months, this matter is a fool's dream.

The reason is very simple, the Mongolian army in Liaodong is ready to attack the original city in late April, when the general of the Mongolian army in Liaodong will send 30,000 Mongolian soldiers to reinforce the Mongolian army in Yinzhou City, so that Yinzhou City has 70,000 Mongolian troops, plus the prepared siege equipment, it is enough to take Kaiyuan City.

The envoy of the Mongolian army returned to Yinzhou City and told the scene of meeting Li Yuntian to Mansu and Mudu, portraying Li Yuntian as an arrogant, unreasonable, arrogant and arrogant son of a nobleman.

Although the envoy of the Mongolian army did not know Li Yuntian's identity, he knew the military system of the Ming army, and Li Yuntian was able to control the military and political power of Kaiyuan City at a young age, and he was obviously the son of a nobleman.

Regarding Li Yuntian's capture of Yinzhou City within three months, both Mansu and Mu did not take it to heart, thinking that Li Yuntian was just a quick talker, and when the reinforcements of the Mongolian army arrived in Kaiyuan City, it would be broken, and then they could humiliate Li Yuntian, who did not know what to do.

Li Yuntian said that the news of the attack on Yinzhou City within three months soon spread throughout Kaiyuan City, which made the soldiers and civilians of Kaiyuan City who panicked because the Mongolian envoys spread the news of the defeat of Emperor Xuande's northern expedition greatly boosted their morale, and it was obvious that they believed Li Yuntian who spoke loudly, if Emperor Xuande's northern expedition failed, how could Li Yuntian be full of ambition to attack Yinzhou City?

Although the situation in Kaiyuan City was stabilized by Li Yuntian, Gu Liyu and Pei Jun finally realized that something was wrong, because the two had never heard Li Yuntian talk about the official document of the imperial court about the triumph of Emperor Xuande, which was good news to encourage the army.

Li Yuntian knew that he couldn't hide Gu Liyu and Pei Jun, so after meeting the Mongolian army envoy in the reception hall, he called the two into the office room, and quietly handed the official document sent by the military pavilion to Gu Liyu.

"Master Hou, what should we do?" Gu Liyu opened it and saw that his face suddenly changed, and he looked at Li Yuntian with a shocked expression.

He really couldn't imagine why the originally Shunshun Lìli's northern expedition suddenly failed, and the 190,000-strong army was almost completely annihilated, which meant that the imperial court would not care about the Ming army in Liaodong and focus on dealing with the southern invasion of Arutai.

"Take Yinzhou City, then reinforce Shenyang City, and force the Mongol army to fight a decisive battle between Shenyang City and Liaoyang City!" Li Yuntian pondered for a while, came to the topographic map of Liaodong hanging on the wall on the side, stretched out his finger and pointed to Yinzhou City and Shenyang City in the south of Yinzhou City, and said quietly.

Among the several important military towns defended by the Ming army in Liaodong, Liaoyang City, the seat of Liaodong Metropolitan Division, and Shenyang City, the seat of Shenyang Zhongwei, were the most fortified, and the Ming army gathered the most.

Once Li Yuntian led his army into Shenyang City, it would force the Mongol army besieging Liaoyang City to make a dilemma, one was to avoid the retreat of the Ming army led by Li Yuntian from Liaoyang City, and the other was to concentrate on a decisive battle with the Ming army led by Li Yuntian.

There was no doubt that the generals of the Mongol army would not let Li Yuntian come into contact with the Ming army in Liaoyang City, so if they wanted to fight Li Yuntian in a decisive battle, they would definitely choose the place between Liaoyang City and Shenyang City.

"Master Hou, there are 40,000 Mongolian troops in Yinzhou City, and although our army has the advantage in strength, it is not necessarily their opponent." Hearing this, Pei Jun couldn't help but be taken aback, and hurriedly reminded Li Yuntian.

The reason why Gu Liyu defeated the Mongol army before was because he adopted the strategy of surprise attack at night, which made the cavalry in the Mongol army ineffective, and took advantage of the chaos to achieve a victory.

It is conceivable that if the Mongol army in Yinzhou City knew that the Ming army was coming to attack the city, I am afraid that they would pour out of their nests to engage the Ming army in the field, and the Mongolian cavalry naturally needless to say, once the charge was unstoppable, even the Mongolian infantry was extremely strong in its individual soldiers.

If the battle between the two sides is at a stalemate, then the only one who can compete with the Mongol soldiers is the Xiaowu army, although the Liaodong Ming army in Kaiyuan City has been training for several months and its morale is high, and its combat effectiveness has improved a lot, but it cannot be compared with the Xiaowu army, and in the face of this kind of fierce battle, it will have more than enough strength and will collapse in the battle.

The soldiers of the Jurchen tribes can shake the Mongol soldiers, but they do not really identify with the Ming Dynasty in their hearts, just like the Ming still regard them as barbarians, except for the Jurchen soldiers of Jianzhou Wei who may put up a stubborn resistance, the Jurchen soldiers of the western and eastern China Sea will definitely withdraw, how can they fight to the death with the Mongol soldiers for the Ming Dynasty?

Gu Liyu also realized that the Liaodong Ming army and the Jurchen soldiers could not fight a tough battle, but he did not feel anxious like Pei Jun, but looked at Li Yuntian with interest.

Unlike Pei Jun, Gu Liyu is Li Yuntian's old subordinate, so he knows that Li Yuntian has always planned and then acted when he does things, since he proposed to attack Yinzhou City, he must have taken into account the factors of the Liaodong Ming army and the Jurchen soldiers, and thought of a way to deal with it, otherwise he would definitely not rush to send troops.
