Time into the end of March of the fourth year of the Apocalypse, the snow in the Changbai Mountains began to melt, most of the Jurchens had left the Changbai Mountains into North Korea, Sun Chuanting's defense was taken over by Mangui, Mao Wenlong took his mountain infantry cavalry soldiers into the depths of the Changbai Mountains to look for the Jurchens who could be expelled everywhere, Zhao led the troops to gradually advance to the Yalu River, and by the end of May, Xiong Tingbi's subordinates finally took control of the Changbai Mountains and cleared all the Jurchen forces west of the Yalu River. Nearly 600,000 Jurchens, men, women, and children, all moved to North Korea.

Sun Chuanting's troops have returned to the Horqin grassland, and Cao Wenzhao was also ordered by Xiong Tingbi to follow Sun Chuanting and accept Sun Chuanting's command, and since then he has become Sun Chuanting's subordinates, and now Sun Chuanting has nearly 60,000 light cavalry, and it is beyond the reach of the Mongolian Lindan Khan tribe who have survived the cold winter to return to the Horqin grassland.

With the westward march of 200,000 road construction troops, the road from Xi'an to Lanzhou has been repaired, and Yuan Yingtai, the governor of Shaanxi and Gansu, is now sitting in Lanzhou, and more than 50,000 people under Yuan Chonghuan are also stationed in Lanzhou. After a year of recuperation, Yuan Chonghuan's subordinates have not only been greatly supplemented, but also improved the combat effectiveness of the terror, 20,000 Hetao light cavalry plus 30,000 cavalry, can be called a strong horse, Yuan Yingtai's local governance ability is really not said, logistics support ability makes Yuan Chonghuan admire incomparable.

Bu Shitu Taiji went all the way south from the Hetao area, and finally returned to his old nest Qinghai, but this place is not what it used to be, because he took most of the clansmen with him when he left, and this place was invaded by the forces of Wu Sizang, fortunately, there are still close branches of his tribe here to support it has not been completely extinct, and when he returns, Bu Shitu Taiji immediately began to integrate the forces here. Although the battle against the Ming Dynasty's Hetao light cavalry was vulnerable, his tens of thousands of troops here can be called strong and strong, and soon built up his sphere of influence around Xining, in order to deal with the Ming army, but also communicated with the upper echelons of Wusizang, recovered various nearby forces, and quickly controlled the northern half of Qinghai.

Yuan Chonghuan's first target to attack is Xining City, now it has initially possessed the prototype of the city, in the Western Han Dynasty here was named Pingxi City by the general of the Western Expedition, since then it has been gathering the population of various ethnic groups here, now this is the center of Bu Shitu Taiji's rule, as long as Xining City is captured, Bu Shitu Taiji will completely lose his hometown, as for the next direction of attack, it depends on the direction of Bu Shitu Taiji's escape, of course, it depends on the logistics and supply situation.

Zhu Youxiao naturally knows how much it takes to enter the Qinghai-Tibet Plateau, but if he can't subdue and settle down in Qinghai now, he will always have a bad situation of being attacked by the enemy on his back, and the biggest enemy in Qinghai-Tibet is not people, but the harsh plateau climate reaction, and if he enters an altitude of more than 3,000 meters, he will feel difficult to breathe, and if he wants to enter an area above 5,000 meters above sea level, the Ming army will probably lose its combat effectiveness. Fortunately, Zhu Youxiao came from later generations, he knew that there is a grass called Rhodiola, which has a very good anti-altitude sickness effect, it not only grows in Qinghai, Tibet, but also in the Mongolian Plateau, in order to ensure that Yuan Chonghuan can successfully take Qinghai, he has already prepared a lot of this Rhodiola, and told Yuan Chonghuan that after arriving in Qinghai, it is necessary to find and purchase a large number of this grass, once into the depths of Qinghai, it is necessary to boil water with Rhodiola every day to ensure that every soldier can drink a small bowl.

The soldiers and horses attacking Qinghai were led by Hong Chengchou and Hao Yongzhong as the vanguard with 5,000 men and horses, and then Yuan Chonghuan led 15,000 brigades to suppress the formation, and his subordinate generals included Li Hongji, Liu Zongmin, and Li Guo, as well as nearly 10,000 logistics supply teams. Lu Xiangsheng led 30,000 people to Suzhou in accordance with Zhu Youxiao's will, preparing to enter the Xinjiang region, which is now divided into several tribes by the descendants of several Genghis Khan, and the tribes are constantly fighting each other.

Enter the first pass of Qinghai, the first pass is called Shangchuankou, Ming Hongwu four years (1371), Yuan Xinning Prefecture Tongzhi Li Nange descended to Ming, granted hereditary command of the affairs, called "Tusi", Shangchuankou is its fief. In the fourteenth year of Jiajing of the Ming Dynasty (1535), the Kawaguchi Fort was built, and then the troops were prepared to build the beacon pier in Zhoujing. It is still the Li Toast who guards Kawaguchi Fort, but he has become the last Bu Shitu Taiji, after all, they all belong to the same clan.

Hearing that the vanguard of the Ming army had arrived, this Tusi did not know whether he was alive or dead, and he actually came to meet him with 3,000 native soldiers. When Hao Yongzhong arrived with a forward of more than 1,000 people, Li Tusi's men and horses had already formed a formation in front of Kawaguchi Fort, and there were many cheering gong and drum teams standing behind. Hao Yongzhong looked at these people and laughed in his heart, did he want to "fight" first and then launch a charge after the team was so neatly arranged? Although Hao Yongzhong also wants to play "fighting generals", it is a pity that Hong Chengchou will not let him do this, the biggest fighting principle of the Ming army is to "protect yourself and destroy the enemy", and the highest level is to fight without damage, if he dares to play "fighting generals" today, Hong Chengchou will also slap him thirty times if he wins.

Hao Yongzhong also wanted to tease this Li Tusi to have fun, and when the two teams were half a mile apart, Hao Yongzhong ordered the troops to stop, let the soldiers in the front row cover the small mortar, and he led a team of thirty people forward, Li Tusi also thought that Hao Yongzhong wanted to talk in front of the battle, and also brought more than thirty people to ride over. Just when they were more than ten zhang apart, Hao Yongzhong waved his hand, and more than 30 people raised the firing pistols in their hands at the same time, aiming at the opponent's squad is a platoon, at the same time, the Ming mortars who heard the gunshots immediately opened fire, and in a flash, the Tusi team was in chaos, and soon the Ming army launched a charge after three rounds of artillery bombardment. Hao Yongzhong's squad had already begun to charge after the first round of shelling, and Li Tusi, who had been beaten, still wanted to be reasonable? Before he could react, Hao Yongzhong's squad rushed to the front, another round of arm crossbow shooting, Li Tusi was hit by a crossbow arrow, and then was captured alive by Hao Yongzhong, and then the Ming army who rushed over quickly routed these overturned native soldiers, and then rushed into Kawaguchi Fort before closing the forts, waiting for Hong Chengchou's arrival.

After Hong Chengchou arrived at Kawaguchi Fort, he listened to everyone talk about how Hao Yongzhong outwitted Kawaguchi Fort, and Hong Chengchou was also laughing, and rewarded Hao Yongzhong with a slap on the back of the head: "Good boy, you are also a smart hemp!" ”

Next, waiting for Yuan Chonghuan to rush to Kawaguchi Fort with the main force of the brigade, and rested for a day, Yuan Chonghuan was just about to order Hong Chengchou to continue to march to Nian Beiwei, Li Hongji spoke: "My lord, let me lead the team this time, okay?" Let me try General Hao's method too, okay? ”

Out of the training of the young generals, and Yuan Chonghuan also has a very good impression of Li Hongji, so he said: "Yes, but you can take Liu Zongmin and Li Guo to exercise together, be careful on the road, everything can happen, don't panic in case of trouble." ”

Li Hongji immediately replied: "Yes, obey." ”

And it is said that this mill Beiwei is the original guard of the Ming Dynasty, located in the Huangshui Valley and the mountains on both sides, the north and south are high and the middle is low, the landform is dominated by river valleys and valleys and middle and low mountains and hills, and the Huangshui River flows through the territory from west to east. Li Hongji took 3,000 men and horses under his command, and constantly sent scouts all the way, and cautiously drove forward, this was the first time Li Hongji led his troops to be a pioneer, and he was afraid that something would go wrong and he would not be able to explain to Yuan Chonghuan.

The soldiers went to the Huangshui River, and the horses returned, saying that there were nearly 10,000 people and horses from Bu Shitu Taiji on the other side of the river, and then rushed to the river. Li Hongji pondered for a while, and discussed with Liu Zongmin and Li Guo, Bu Shitu Taiji's men and horses probably want to block along the river, if the other party occupies the opposite bank, the crossing of the river will definitely be restricted, it is better to learn from the overlord of Chu to make a backwater blow, in order to be perfect, it was decided that Li Guo would arrange a small mortar position on the north bank of the Huangshui River, and Li Hongji and Liu Zongmin would lead the team to cross the river. This Huangshui River is only about 30 zhang wide, and it is not the rainy season yet, so there is not much problem with riding a horse to float across.

So, Li Hongji and Liu Zongmin each took 1,000 men and horses, and the two of them, as the leaders, led the team to swim to the opposite bank, and the speed of crossing the river must be slower than the speed of flat land, just when Li Hongji and they were just about to go ashore, Bu Shitu Taiji's men and horses appeared on the river embankment, and the forward was less than 30 zhang away from Li Hongji, and Li Hongji immediately ordered the soldiers who had crossed the river to line up to cover the men and horses behind to cross the river.

Li Guo on the north bank saw that the opponent's forward was ready to charge, and gave an order, and suddenly the small mortars fired together, which was nearly seventy or eighty zhang is the best firing distance of the small mortars, and for a time covered the charging route of the opponent's forward, after five rounds of artillery bombardment, Li Hongji's men and horses had already crossed the river, and then Li Hongji and Liu Zongmin led the team to charge, and these disabled Bu Shitu Taiji troops quickly retreated. Li Hongji and the others did not chase after them, but just straightened out their men and horses to cover Li Guobu's crossing of the river.
