Zhu Yunwen's strategy is actually a typical farmer's thinking, building a fence, defending and counterattacking, gradually encroaching, and never taking risks. And his subordinates such as Ping'an, Sheng Yong, Xu Huizu and others are also slowly getting used to his set of thinking. So far, this strategy has been relatively successful, so there are not many voices of opposition.

In order to solve the problem of grain and grass, Zhu Yunwen not only ordered Jiangnan to ship grain to Liaodong, but also implemented the law of opening up China to encourage merchants to transport grain to the northeast; In order to calm people's hearts, he changed his younger brother Zhu Yunxi from King Heng to King Ji, and gave Changchun 50,000 acres of land, 10,000 stones a year, and three guards; Ordered Zhu Mo, the king of Shen, to take Shenyang to the domain, give 10,000 acres of land, 10,000 stones a year, and give two guards.

Of course, Changchun doesn't even have a shadow now, let alone the palace. Even so, Zhu Yunwen ordered his younger brother to rush to Shenyang immediately, familiarize himself with the situation nearby, and be ready to take up the vassal at any time.

As soon as this holy decree came out, Zhu Mo didn't dare to say anything, but Zhu Yunxi was very dissatisfied, and ran to his mother Empress Dowager Lu to cry, saying that the emperor's brother bullied him, and Empress Dowager Lu was immediately furious when she learned about it, Zhu Yunxi is her biological son, and Zhu Yunxi who was sealed to Taiwan is still different. Therefore, Empress Dowager Lu came to Beiping with Zhu Yunkeng, along with Zhu Yunwen's concubines, and Queen Ma Hui still sat in Beijing to assist the crown prince Zhu Wenkui in supervising the country.

However, Zhu Yunwen has been the emperor for six years, and he has already made up his mind, and the Empress Dowager Lu is helpless. In the end, Empress Dowager Lu asked to increase Zhu Yunxi's Yulu and asked to allow Zhu Yunxi to come to the court every year. Zhu Yunwen naturally agreed to these conditions, increased his salary to 20,000 stones, and allowed him to come to the dynasty every year, without the restriction of the vassal king's three-year dynasty.

Of course, Zhu Yunxi's visit to Changchun was not expected to play any role, but more of an exemplary significance, showing Zhu Yunxi's determination to open up the northeast, which is of great significance to both military operations and economic construction.

The Mongols, with Mahamu as the commander and Arutai, Tieleba, and Sumu as the deputy commanders, divided their troops into two routes and entered the northeast. Among them, Arutai and Tieleba enter the northeast from the old land of Wuliangha--- the Guan'er River and Nenjiang River basins; Mahamu and Sumu enter the northeast from the vicinity of Tongliao.

Mahamu and Sumu led their troops to Kaiping for a circle, had a skirmish with Xu Huizu, and then turned to the northeast. Seeing this, Xu Huizu immediately asked for his life to go straight to Bear Lake, but was vetoed by Zhu Yunwen. Zhu Yunwen ordered him to train his soldiers and horses, and was ready to support Liaodong at any time.

In response to the Mongol invasion, Ping'an ordered to build more than 20 barriers along the mountains and rivers along the line from Tieling to Tonghua, with 200 defenders placed on each barrier, equipped with muskets, artillery and grenades. After encountering the invasion and plundering of the Mongols, they were not allowed to fight, as long as they set off beacon fires for help, and the cavalry of Liaodong was also on standby, ready to support at any time.

This simple tactic immediately put the Mongol army in a dilemma, at this time the Liaodong Peninsula was far less developed than in later generations, its most developed area was only in the Tieling, Shenyang south of the peninsula area, if blocked outside Tieling, Tonghua, then the Mongols could only rely on hunting for a living. Moreover, the Tieling and Tonghua rivers are vertical and horizontal, and the hills are all over the place, which is not suitable for cavalry combat, and is more suitable for infantry to attack fortifications, such a terrain is not conducive to the Mongols, but to the Ming army.

Moreover, the core area of the Ming army was concentrated in several cities such as Shenyang, Tieling, Fushun, Liaoyang, and Dalian, which were impossible to conquer, and the Ming army was still increasing troops towards Liaodong.

If you can't conquer the big city, you can only plunder the wilderness. But there is also a problem, most of the people near Ayutthaya are Han Chinese, with the protection of the Ming army, and in the farther part of Ayutthaya, it is mainly the Jurchens, but most of the Jurchens are poor, except for some rations allocated by the imperial court after naturalization, there is nothing else. The Mongols came under the banner of supporting the Jurchens, and it seems that the targets of looting aid are not very good.

But people always had to eat, and soon, plundering the rations in the hands of the naturalized Jurchens became a common choice for the Mongol army and the Jurchen army. But unlike the Mongols, the Jurchens not only plundered their own food, but also forced them to migrate and join their ranks; But this practice instead provoked the naturalization of the Nuzhen rebellion, although they were also against naturalization at the beginning, but they felt that it was not bad to be truly naturalized, the court gave them land, helped them build houses, and distributed rations to them, as long as they have an identity card, they can enjoy the treatment of the Ming people, and even get the protection of the Ming army, what is not satisfied?

After a period of contention, both the Mongol army and the Jurchen army withdrew north of Tonghua, because they were no opponent at all when they fought in the narrow hell of the peninsula, and the well-equipped First Guards Cavalry Army was invincible in Liaodong; Shao Yun's Seventh Guards Infantry Army was as quiet as a copper wall, and it was invincible when it moved.

……

Tonghua City, the deputy general of the expedition to the north.

There was silence in the big tent, An Pingbo Li Yuan was reading the letter, and Wang Zhong, Xiong Hai and others next to him stood solemnly on both sides, not squinting; And kneeling in the hall was a thin man dressed as a Jurchen, with the top of his head shaved all around and a pigtail in the middle, full of joy.

After a long while, Li Yuan put down the letter and said with a smile: "This messenger, what is your name?" ”

"Go back to the general, the little one is called Alhatu!"

"Alhattu?" Li Yuan turned his head suspiciously and looked at Changshi Han Ziguang. Han Ziguang bowed his head and said, "It's the meaning of the scheme!" ”

"Hehe," Li Yuan smiled, then held up the letter and said, "Alhattu, what does Brother Meng's Timur mean?" Hasn't he become the king of the West Sea of Li Fangyuan? How did you remember to write a letter to General Ben? ”

"General, you're laughing!" Alhatu bowed to the ground and said: "Li Fang is far from just a clown who jumps off the beam, and he is just a monkey and a crown, and Brother Meng is just a snake with his hypocrisy, and the adult is dedicated to Daming!" ”

"Dedicated to Daming?" Li Yuan suddenly said sharply: "Why did Brother Meng, Timur, join forces with the Mongolian army to plunder my Ming people and besiege my Tonghua City?" ”

"Your Excellency Shogun! Shogun! Alhatu kowtowed again and again: "The adults of my family are lonely, and it is difficult to speak alone, the king of Qinghai, ah, no, it is Li Zhongzhong who holds the military power, and the Mongols are compelling, and my family has to pretend." ”

"But my family is in Cao Ying, and his heart is in Han, and he has never robbed the people in person, and he also ordered his subordinates not to harm the lives of the people of the Ming Dynasty! It's all true! Please be careful! ”

Li Yuan was silent for a while, then suddenly slapped the table with a "snap", and said coldly: "Nonsense!" Brother Meng's Timur clearly saw that Seoul was broken, and Li Fangyuan was at the end of his rope, so he wanted to find a way back, right? ”

"My lord Mingjian, that's not the case, my family has always planned to return to the Ming Dynasty, but I didn't find the opportunity. Now that Li Fang is far from being poor, Li Zhongzhong is frightened, and the adults in my family feel that the time is ripe, so they specially come to beg for surrender to the adults. ”

"Begging?" Li Yuan smiled and said: "Yes, General Ben is approved, when will Brother Meng's Timur come?" ”

"This," Alhatu said with some hesitation: "Lord Mingjian, Brother Meng is very willing to come alone, but he also has many loyal subordinates, all of whom are loyal ministers with a heart for the Ming Dynasty, so what my lord means is ......"

"What is it?"

"My lord hopes to be able to make a war exploit and surrender again!"

Alhatu wanted to wait for Li Yuan to ask, but found that Li Yuan said impatiently: "If you are not willing to surrender, it is not uncommon for this general to go." ”

"No, no, no! General, the number of troops under the control of Brother Meng is already 8,000, which is almost the same as Li Zhongzhong's strength, and the Mongolian army has moved westward, as long as the adults send troops to attack Li Zhongzhong, my family can start an incident in the rear and eliminate Li Zhongzhong in one fell swoop. ”

"What?" Li Yuan Huoran stood up: "The Mongols moved west? Where did you go? ”

"My lord, it is like this, now that the Mongol army and the Jurchen army have a disagreement, Li Zhongzhong advocates attacking Tonghua, and then crossing the Yalu River, attacking Lelang Mansion to support Li Fangyuan; The Mongol army has come from afar to no avail, and has the intention of retreating, so the two armies have been divided, and they have retreated in the direction of the Songhua River, and it seems that they have a tendency to return to the steppe! ”

Li Yuan slowly sat down and said, "The Mongols don't care for the time being, what is the plan of Brother Meng's Timur?" ”

"Our army is now stationed in the northeast of Tonghua, at the eastern foot of Changbai Mountain, the general can attack at night, Li Zhongzhong will inevitably be caught off guard, and Brother Meng can raise troops from behind and annihilate Li Zhongzhong in one fell swoop."

"Then take my family as the precursor to lure the Mongolian army into an ambush, and the adults can notify General Ping'an to annihilate the Mongolian army in one fell swoop, so that Liaodong can be decided in one fell swoop!"

"In one fell swoop?" Li Yuan was overjoyed, pointed to the map and said: "Li Zhongzhong is easy to solve, what about the Mongolian army?" Where is it better to ambush them? ”

"Please allow the villain to point on the map."

"No problem, you get up."

"My lord, please see, this is the source of the Liao River, with abundant water and plants, and abundant products!" Alhatu tapped on the map and said, "The Mongols' tent has always been set up here, and it is a good place for ambushes!" ”

Li Yuan and the generals in the account looked over, that place, later generations called Liaoyuan.
