After Sun Chuanting dispelled Oba's concerns, he looked at Sang Jae Bu and stopped talking, and asked him, "Father-in-law, do you have anything to say?" Don't worry, don't worry. ”

Zaisang Buhe said: "I don't have any worries, but can I let my eldest son Wu Keshan go on the expedition with you?" I can't go with you, but Wu Keshan is young and strong, and his martial arts are also good, so I can rest assured that I will follow you, do you think it is okay? You don't have to worry about things at home, I will definitely help you take care of Hai Lanzhu. ”

"Okay, be my personal guard." Sun Chuanting said.

However, Zaisang* Bu and this sentence reminded Oba that Zaisang* and Bu let their sons go with the army to be hostages, and Oba immediately said: "General Sun, my two sons are also good, and I plan to follow you to exercise, do you think it's okay?" ”

Sun Chuanting now understood what Zaisang Buhe meant by letting his son follow him just now, so he said without hesitation: "Go to a son, you also need to take care of it, be my escort like Wu Keshan, I will definitely take care of him, please rest assured." ”

After pacifying Oba and Zaisang*Buhe, Sun Chuanting reorganized the soldiers who were preparing to go on the expedition, and by this time Cao Wenzhao had already rushed to the Horqin steppe with 5,000 men and horses and a large number of supplies. For Cao Wenzhao's name, Sun Chuanting has also heard of it for a long time, this general who grew up from a soldier is both wise and brave, this time Xiong Tingbi sent him to assist him, it seems that Xiong Tingbi is full of confidence in himself.

Judging from the sketchy map, if you want to carry out a large roundabout outflanking route, you must first set off in the direction of due north, until you reach the Qiqihar region of later generations, but now it is not called Qiqihar, it is just a guard post of the Ming Dynasty, part of the Horqin grassland, and it is now a small gathering place of the Jurchens. Sun Chuanting planned to start from here as the first target of the war, and then sweep the east slightly northerly, from the current location is about the future Tongliao City, all the way north to the destination is the grassland area, not far to the north Baicheng area is under the control of the Horqin tribe, can be used as a good supply location. In this way, Sun Chuanting had an approximate battle plan.

On the 11th day of the seventh month of the third year of the Apocalypse, Sun Chuanting led more than 50,000 horses under his command to march towards Baicheng in a mighty manner, followed by more than 10,000 supply teams sent by Oba, and there were also a lot of horses here, weapons and ammunition can be carried by horses, and there is not much food, but the salt must be prepared sufficiently, if there is a lack of edible salt, this battle will not be easy to fight. Of course, for the whole cavalry unit, the distance of nearly 4,000 miles from Tongliao to Qiqihar is not too far, and the 400 miles walk every day except for rest time should be about the same, and it can be reached in about ten days. After three days of marching, Sun Chuanting's brigade arrived in the present-day Baicheng area, where he met a 600-strong mountain cavalry battalion led by Shang Kexi. Shang Kexi respectfully met Sun Chuanting and told him about his coming here.

It turned out that after these arrogant soldiers under the command of Mao Wenlong received the reconnaissance order, they entered the territory of the Jurchens one by one as if they were bloody, and they did not stop for a while. Shang Kexi led his six hundred people, non-stop to the north, encountered a smaller tribe and killed it cleanly, and then seized food, salt and other materials to be sent to the guard here in Baicheng, one person, three horses or even four horses, scattered on the entire Songnen Plain, in less than half a month, I had a rough understanding of the terrain of this generation and the distribution of the Jurchens, and now I met Sun Chuanting just after returning here. Shang Kexi is arrogant, who has to be in front of him, Sun Chuanting is a celebrity in front of the emperor, and Shang Kexi is even smarter, so he is very respectful.

After getting the information that is still gratifying, Sun Chuanting is even more confident in his heart, now there are only more than 200,000 Jurchens in the entire region, and there are more than a dozen tribes living in Qiqihar, and there are more than 30,000 people, so it seems that there is no need for the army to pass, just let Cao Wenzhao lead 15,000 people, just let Cao Wenzhao lead 15,000 people, like the later generations said "Manchurian is not more than 10,000, more than 10,000 are invincible", now there is no need to worry, the rest of the brigade can now sweep in the direction of the north-east.

So, Cao Wenzhao led 15,000 people, 30,000 horses, under the leadership of the scouts sent by Shang Kexi, day and night to the direction of Qiqihar, the current weather is very suitable for marching, encountered the swamp area to bypass, after three days of rapid marching, arrived at the designated area, Cao Wenzhao used the troops carefully, first rested for a day, and then began to sweep. The first thing they met was a tribe of about 2,000 people, about 800 people of young and strong, when they saw the Ming army, they did not hesitate to rush up in a group, when they were close to half a mile, Cao Wenzhao gave an order, more than 200 mortars fired together, after three rounds, there were not many people on horses, and then without waiting for Cao Wenzhao to charge, the remaining Jurchens were like ghosts, turned around and fled, Cao Wenzhao urged the troops to follow up, and a tribe did not have 500 people left and fled in all directions.

On the third day, when Cao Wenzhao arrived at Tucheng, where the Jurchens gathered, he saw a series of tents of more than ten miles, and in front of Tucheng, there was a team of four or five thousand young people. These Jurchens had already received the news, and it only took one day to gather the tribes within a hundred miles of the vicinity, because the nomadic tribes did not have much possessions, and they could ride on horses and go.

Seeing the arrival of the Ming army, these Jurchens did not have a long memory, they still rushed up in line, the result was naturally tragic, after the artillery platoon, the people turned on their horses, and the small Tucheng naturally did not dare to go back, and they all ran to the tents in their tribes, and the mountain infantry battalion squadron that was outflanked to the back in advance also put small cannons from the direction of the north, and the only place where these Jurchens could run was the east, so the twenty or thirty thousand Jurchens fled desperately to the east like a swarm. Cao Wenzhao ordered his men and horses to disperse and desperately sweep from south to north, expelling the Jurchens in the direction of the east. There were also many people from the Yehe tribe in the mountain riding camp, and they scattered in all directions, spreading the news in fluent Jurchen dialect, "Hurry up and run east, the Nurhachi tribe is going to conquer Korea." "North Koreans have less money and more money, and if they go late, they won't be able to get their possessions." "The Ming army is too powerful, they will use heavenly thunder." And so on, the Jurchens lived in tribes, and the news was not well-informed, and rumors spread for a while, but in the case of the Ming army driving around, the entire Jurchens on the south bank of the Heilongjiang River migrated to the Yalu River like flowing water.

Sun Chuanting, who originally thought that he needed to fight a few tough battles, found that there was no resistance on the way forward, except for the march on the road, he rested, and none of the hard stubbles were encountered, and the initial caution became meaningless, and later I learned that it was just the chaos caused by Shang Kexi's subordinates. As a result, Sun Chuanting no longer held back, but divided his tens of thousands of people into a team of 2,000 people, each subcontracting an area, and striding forward. However, Sun Chuanting still strictly ordered all departments not to be careless, and when they advanced to the front line of the Mudanjiang River, they must gather together.

By the beginning of September, Cao Wenzhao's men and Sun Chuanting's main force had finally advanced to the line from what is now Harbin to the south to the Mudanjiang River. Sun Chuanting's troops are in good shape, Cao Wenzhao's troops have all become rags, this is not a war, it is a runaway, in less than two months, it has been going around in circles, no one has to be tired? Fortunately, Cao Wenzhao can use soldiers and lead soldiers, although his clothes are in tatters, his spirit is still quite good, Sun Chuanting immediately supplied them, let them rest and recuperate, and wait for Xiong Tingbi's next order.
