In Datong City, Cao Yue's general army was in the middle of the line, and Cao Yue was discussing things with Sun Chuanting.

The imperial court officially issued an edict and entrusted Sun Chuanting with the military affairs of Shanxi, Shandong, Henan, and Shaanxi, that is, from the day the edict was issued, Sun Chuanting could mobilize any army in Shandong, Henan, Shaanxi, and Shanxi.

Of course, this is theoretical.

Nowadays, not many people take the edict of the imperial court seriously, and many generals who do not obey the edict go, which Emperor Chongzhen knows, and Sun Chuanting also knows. Now Sun Chuanting relies on Cao Yue's Datong Army the most, and Cao Bianjiao, who doesn't know when he will be able to return to the account. Other people, including Liu Zeqing in Shandong, He Renlong and Jiang brothers in Shaanxi, and Zhou Yuji in Shanxi, did not have great hopes.

Cao Yue defeated Dolgon under Datong City, and Sun Chuanting certainly set his sights on this team without any suspense. He was already thinking about how to take this group of men for himself. However, everything has to survive this war before it is possible to say anything else, if Datong can't hold it, then he and Cao Yue can only die here, and there is no future.

Cao Yue asked him what the ultimate purpose of Emperor Chongzhen sending him to Datong was, Sun Chuanting just gritted his teeth and didn't say anything, and Cao Yue didn't say anything about threats and temptations. He told Cao Yue that if Datong was defeated and Jiannu was repulsed, he would definitely tell Pan the purpose of the trip, and he would also support Cao Yue's big move, and he would always help him in the future.

The conditions given by Old Man Sun were still quite generous, and Cao Yue also believed him for the time being, and now that the battle situation was urgent, he didn't ask again.

"General Cao Bing, you said that all the twenty-one red-coated cannons of Jiannu arrived in Datong City?" Sun Chuanting sipped tea and asked Cao Yue slowly: "Didn't you say that you sent elite men and horses to harass along the way?" ”

"Old man Sun, don't make a mistake, Jiannu's original artillery was thirty-one artillery, ten of which were destroyed by my soldiers, and only twenty-one of them finally arrived in Datong, and more than thirty percent of the cannons were destroyed by my soldiers. Do you know how powerful ten redcoat cannons are? Do you know how much effort and sacrifice my men put in to destroy the artillery? That's the artillery battalion of 20,000 Jurchen elites led by Duoduo personally," Cao Yue glared at Sun Chuanting angrily, "Don't yell here all day long, Datong City is full of soldiers trained by me, and your old life is also for the protection of my soldiers, believe it or not, tie you to the city as a target for Jiannu?" ”

Cao Yue is neither big nor small, Sun Chuanting didn't care at all, he still leaned leisurely, drinking tea slowly: "Stinky boy, how powerful you brag about your soldiers, what are you called special forces, what are special forces, you have also explained to the old man, now it seems that they are not more than Erer." Don't blow too much of your cowhide, in case you can't hold it, we'll all finish playing!"

"Didn't you have so many titles and command the military affairs of several provinces? Why can't even the reinforcements be brought in? Cao Yue was still not angry.

"Isn't Zhou Yuji willing to send troops to help you stop the rogue? Jiang Xuan's two brothers should also say that as long as they help you block the Liukou, then let Jiannu attack the city. Wei Daben has raised tens of thousands of young people, and they can also be used to defend the city at critical moments!" Sun Chuanting said, put away his joking look, and asked Cao Yue seriously: "Cao Yue, let me ask you, how sure are you that you will defend Datong City?" ”

"Old man Sun, I should ask you this, you are now the supreme military commander of Datong, and all the armies of Datong are under your command!"

Sun Chuanting touched his nose in embarrassment, and said with a smile: "Your centaurs, can I command them?" ”

Cao Yue couldn't help but roll his eyes, "Don't say that, if you play to the court like this, the emperor will relieve me of my military power!"

Having said that, Cao Yue did not have the slightest worry, he knew that Sun Chuanting would not impeach him to the imperial court. It's very interesting to talk to Old Man Sun, it's exactly like when you were with those iron buddies in the later life, you can talk nonsense without any scruples.

Sun Chuanting almost choked on the tea, coughed vigorously twice and waved his hand, "Okay, don't talk so much nonsense, let's discuss how we should deal with the large-scale siege of Jiannu!" Now, except for the south gate, which is not completely surrounded by Jiannu, the other three have been surrounded by them, and after the arrival of Jiannu's red-clothed cannons, it will definitely help to borrow the power of artillery to attack the city on a large scale. This siege, the posture is definitely different from the past. ”

"Old man Sun, if not, I will personally command the defense of the north gate and the west gate, and you will command the east gate and the south gate, how about it?" Jiannu tried to garrison troops outside the south gate several times, but was beaten away by Cao Yue. Until now, Jiannu has not completely surrounded Datong City, and materials and personnel can still enter and exit from the south gate of Datong.

The power of gunpowder is huge, not the elite cavalry of Jiannu can contend with, Cao Yue relied on a large amount of gunpowder, as well as the advantage of the terrain, to keep the passage between Datong and the outside. Jiannu's troops are not enough, and they want to surround all four directions of Datong, but there is not much possibility. The assault camp of the cavalry of the Datong Army that day made Jiannu have some scruples and did not dare to fight with all his might.

Sun Chuanting also agreed to Cao Yue's suggestion, and the two of them commanded the defense of the two gates respectively, and after careful discussion, they also made preparations.

In the past few days, the siege of Jiannu has decreased significantly, and finally stopped completely, but everyone knows that this is the calm before the big war, and one day in the future, Jiannu will launch a large-scale siege.

Liaodong, Shanhaiguan.

The army of more than 30,000 ordered by Cao Yue's cousin Cao Bianjiao is quickly passing through the Shanhaiguan Pass and entering the pass.

Ten days ago, they received an edict from the imperial court, ordering Cao Bianjiao to lead the army into the customs, obey Sun Chuanting's dispatch, and go to Henan to quell the rebellion. After receiving the order, Cao Bianjiao immediately picked up the 38,000 men and horses under his command, left Songshan, and went to Guannei.

When he arrived near Shanhaiguan, Cao Bianjiao received a secret order from the imperial court, ordering him to change the direction of travel and rescue Datong.

Under the leadership of Dolgon, the army of more than 100,000 Jiannu attacked Datong, and Datong was in danger. After receiving the communication from the imperial court, Cao Bianjiao was naturally surprised. Knowing that his best cousin Cao Yue was under the heavy pressure of Dolgon's army of more than 100,000 people, Cao Bianjiao was so anxious that he couldn't wait to fly to Datong immediately and fight against Jiannu with Cao Yue. After receiving the order of the imperial court to lead his troops to rescue Datong urgently, Cao Bianjiao also ordered his men and horses to move forward as quickly as possible, and strive to reach Datong in the shortest possible time.

"Dolgon, this time, let the most elite Ming border army led by our brother compete with your Jiannu elite to see who will kill the deer!" Cao Bianjiao was not too afraid, but was full of fighting spirit, eager to arrive in Datong immediately and devote himself to the battle with Jiannu.
