Liaodong, Nurhachi suffered heavy losses in the battles of Shenyang and Liaoyang in March, losing five sons alone, three killed in battle and two plundered, plus the loss of Benxiwei and Fushun, and fainted in anger for a while. However, Xiaoxiong is Xiaoxiong, after waking up, he immediately began to deploy the rest of his subordinates, ordered Tieling and Kaiyuan to strengthen the defense, so as not to take advantage of the Ming army, and ordered Daishan to send envoys to the "Hulun Four Divisions" in addition to the three Yehenala Divisions, because in the battle of Shenyang, the Yehenala Department was to take advantage of the situation to fight back, and the other tribes were just defeated and fled, the nature was different, according to Nurhachi's temperament, he must come to kill the chickens and monkeys once, so that the other three tribes knew that they were still their bosses, and this defeat was only occasional, It's not enough to break his muscles and bones, he still has the ability to defeat the Ming army.

Daishan was originally Nurhachi's second son, but because the eldest son had died, Daishan is now the eldest son. Because Huang Taiji, Manggutai, and Abatai fought bravely and performed strongly, Daishan has a tendency to be marginalized, and Daishan is also very low-key, so as not to be assassinated by his brothers. Now, Huang Taiji and Mang Ergutai died in battle, Abatai returned with a fiasco, and the sons who can take charge of themselves are counted by him. Therefore, Dai Shan was sad in the open and happy in secret, and this time he took the gold and silver treasures and beautiful women of the tribe to appease the people of the three tribes. And because the power of these three tribes is indeed too small, they have to continue to obey Nurhachi's dispatch. Dai Shan also persuaded Nurhachi to continue to recruit the Jurchen tribes in the east and northeast on the basis of a solid defense of the west, and not to spare gold and silver treasures. As a result, Dai Shan began to lobby the Jurchen tribes in Jilin, eastern Liaodong, and along the Heilongjiang River, asking them to join their tribal alliance and jointly deal with the forces from the Ming Dynasty.

These Jurchen tribes in the northeast were originally nomadic tribes, living by water, grazing and hunting. They mostly live between forests and grasslands, and they all exist in the form of tribes. It turned out that the Ming Dynasty had set up the Nuergansi to manage these nomadic peoples, and the king of Han was named Yu Kaiyuan, the king of Fengning was in Karaqin, and the king of Liao was in Guangning. The Nurgands mainly administer these farther northeastern regions. Although the kings of Han, Ning, and Liao did not become vassals, this also fully shows that Emperor Hongwu attached great importance to these places, which were the land of the Ming Dynasty.

It's just that since Li Chengliang indulged Nurhachi's development, Nurkansi's control over these areas has gradually weakened, especially after the Battle of Sarhu, Nurgansi has lost its control ability in the south and west directions, except for some control capabilities in Sakhalin. Now Daishan is active in this vast area of the northeast, and those small tribes, looking at the Jurchen cavalry with strong soldiers and horses, as well as the temptation of beautiful women, gold and silver treasures, have gone south to attach themselves to Nurhachi. Therefore, by August, Nurhachi's vitality had recovered a lot, and Daishan was re-recognized for his ability.

Nurhachi, who had recovered slightly, began to move again, constantly sending elite cavalry to harass the common people of the Ming Dynasty who were harvesting the Zhuang family, and on the other hand, subduing other Jurchen tribes to the south and strengthening the domination of the territory he occupied. The Han people who used to cultivate in these places were constantly expelled and plundered, and for a time Nurhachi was in great prominence, and there were signs of a comeback.

Nurhachi also sent more than 20,000 cavalry to threaten the Yehnara tribe, but this time it did not succeed, the current leader of the Yehnara tribe is Niaha, in history, Niaha was defeated and killed by Nurhachi after his father, and brought his younger brother to Nurhachi, although there is a monstrous hatred in his heart, but there is no chance to take revenge, the power of their tribe is too weak compared to Nurhachi, and they can only endure humiliation and steal life.

In this battle of Liaoshen, he found an opportunity, took the opportunity to expand his power, and finally saw the hope of revenge, so when Nurhachi's generals Shulhaqi and Amin came with troops, Nyaha did not succumb to their obscenity as in history, but was determined to resist, because his tribe had rebelled against Nurhachi in the war, and even if he surrendered again, he would not get a good end. Therefore, Niyaha asked the Ming army for help, hoping that the Ming would give the greatest help and jointly fight against the persecution of the Nurhachi tribe.

At that time, the situation in the northeast was quite chaotic, Shenyang occupied by the Ming Dynasty army was the forefront of the entire Ming Dynasty's military power, the east and north were the Jurchen forces, the west was the Chahar Mongol forces, and the northwest was the Horqin Mongols who were friendly with the Jurchens.

At first, the Horqin Mongols were strong and strong, and they continued to plunder the Jurchen tribes to the east, even Nurhachi's khanate was granted by the Mongols, but with the support of Li Chengliang, Nurhachi, the hero, continued to annex other Jurchen tribes, and gradually surpassed the Mongolian Horqin tribe, and then gained the upper hand in several conflicts. Faced with a two-sided threat, the Korqin Mongols allied themselves with Nurhachi and eased their relations in the form of marriage.

The Chahar Mongols sometimes went to war with the Ming Dynasty, sometimes with the Horqin Mongols, and when the Horqin Mongols and the Jurchens became friends, they were a little unbearable, so they no longer went to war with the Ming Dynasty. For Li Chengliang, his goal of using razing to control the country has been achieved, but he has forgotten the ancient precept of raising tigers. Five years after Li Chengliang's death, Nurhachi went to war against the Ming Dynasty, and defeated the Ming army in the Battle of Salhu, which eventually became a disaster.

After defeating Nurhachi in March, Sun Chengzong also vigorously rectified the military and material resources of Liaodong, and formulated a corresponding strategy to deal with the Jurchens. Later, Sun Chengzong was transferred back to the capital, and this headache was handed over to Xiong Tingbi.

After Zhu Youxiao allocated fifteen million taels of silver, his ambition increased greatly, and with the help of craftsmen and technicians sent by the capital, he made a large number of 'two kicking' small cannons and prepared a lot of ammunition. He bought 20,000 war horses from the Chahar Mongols, plus the original cavalry, and formed two cavalry battalions of 15,000 people, which were led and trained by Zhao Shujiao and Man Gui.

Zhao Shujiao was born in martial arts, his own strength is super strong, and this person is very sober-minded, he has been on the expedition with his uncle since he was a teenager, he was once trapped and surrounded, and he escaped with courage and wit.

Man Gui is an alternative, he himself is a Chahar Mongol, since he was a child because his father was killed by the same people, and took his sister to the territory of the Ming Dynasty, rescued by the Han people, and later joined the Ming army, because of its courage and not afraid of death, so he repeatedly made military exploits, with his merits to accumulate the general army.
