There are only a few dozen households in this Zhuangzi, and there will not be many households depending on the situation. However, Cao Yue was still very careful in arranging, he didn't want to be negligent enough to lead to Jiannu who had slipped through the net, so that the news would leak out, and there would be trouble or even disaster.

In several directions outside Zhuangzi, he laid ambush soldiers. Cao Jie and Zhao Liang each took two hundred sergeants and quietly infiltrated Zhuangzi at night.

Soon, screams could be heard in the night, and the sound of heavy footsteps as people ran. However, no one escaped from Zhuangzi, and Cao Yue's ambush outside the village eliminated all those who intended to escape.

After only half an hour's effort, Cao Jie sent someone to report that all the Jiannu had been resolved, leaving three alive, and all the other Jiannu were killed. Thirty Han Chinese were also captured, and several Han Chinese who fled in panic died.

After all the bodies of Jiannu were disposed of and the blood stains were removed, Cao Yue also entered the Zhuangzi, and ordered the sergeants to enter the village to rest, and set up a multi-pull light and dark sentry outside the village. A few days after breaking out of Songshan, the brothers did not have a good rest, nor did they eat a bite of hot rice, there were ready-made houses here, and there was food, so of course Cao Yue chose to rest here.

There were a lot of livestock and grain in the Zhuangzi, and Cao Yue had a few cattle and sheep slaughtered, and a few pots of hot soup and hot rice to give the brothers a full meal, and then replenish the grain that was not surplus. Occupying this Zhuangzi helped Cao Yue solve several problems.

Several of Cao Yue's sergeants knew Manchu, and the three Jiannu who were left behind were asked for confessions. These Manchu sergeants were from Liaodong, and they had contact with the Manchus before joining the army, and even hunted together, and they could speak Manchu and recognize Manchu.

Cao Yue, who was very experienced in interrogating the prisoners, had the sergeant separate the three Manchus for questioning and asking similar questions, which would allow him to identify to a large extent whether the enemy's confession was true or false. For those Han people who were detained together, Cao Yue ordered Cao Jie to inquire about the situation.

It's a bit of a headache to deal with these Han people, it's too cruel to kill them, after all, it's not easy for these Han people to survive until now. But to keep them, Cao Yue was also afraid that the whereabouts of his men and horses would be leaked out, bringing about a catastrophe. There is a bit of a headache.

It took about half an hour, and the three Jiannu finally couldn't stand the torture anymore and told everything they knew.

This is the Zhuangzi of a Jiannu nobleman named Barama, who is the son of Daishan, the prince of Li, who is now left behind in Shengjing. One of the people who left behind his life was a close confidant of Barama's management of Zhuangzi. This Jiannu named Bama knew the situation in Shengjing City in detail, and after some torture, this guy also confessed everything he knew.

Including the situation of the people left behind in Shengjing City, the garrison inside and outside the city, the defense of the palace, the opening of the city gate, etc., Cao Yue wanted to know, Bama basically explained. By questioning the other two people, Cao Yue also basically believed that Bama's explanation was true.

Today, there are really only about 3,000 left-behind people inside and outside Shengjing City, and most of the members are still old and weak, and they are in charge of the left-behind minister, Prince Li, Daishan. Among them, 2,000 men and horses were stationed outside the city, 1,000 people were stationed in the east and west of the city, and the two yellow flag barracks on both sides of the imperial city in the city were only 500 people each, and the guards in the palace were even more people, only more than 200 people.

The defensive strength of Shengjing City is so weak, which makes Cao Yue happy, but how to break through Shengjing City is quite a headache.

Shengjing City closes all the city gates after nightfall, and the city gates are not allowed to be opened without the will of Huang Taiji. Now during the war, Huang Taiji is not in the city, and this power is handed over to the left-behind minister Dai Shan. Without the defense of Dai Shan, the Jiannu guarding the gate would not have opened the city gate. There is no way to deceive the city gate, and if it is attacked, it will definitely not be able to break through the fortified city of Shengjing.

However, the guards of Shengjing City during the day were relatively lax, the Ming army was defeated in every battle over the years, and there was no way to cross the Liao River, Korea and Mongolia had surrendered to Jiannu, and Jiannu had never worried that Shengjing would be attacked by the Ming army.

What's more, now that the last bit of elite of the Ming army is trapped in Songshan, and the roads from Guannai to Liaodong are all blocked, no one would have thought that there would be a surprise attack on Shengjing by the Ming army. Also, there are Hongyi cannons at the head of Shengjing City. After Geng Zhongming, Shang Kexi, and Kong Youde surrendered to the Qing Dynasty, they gave the powerful Hongyi cannons to Jiannu, and most of these Hongyi cannons were erected on the head of Shengjing City. With a strong city and red-coated cannons, it is not so easy for tens of thousands of horses to attack the head of Shengjing City.

I don't have a chance at night, so I can only think of a way during the day. But during the day, an army of more than 1,000 people appeared under Shengjing City, and it was impossible for the defenders not to notice. How can you rush to the city without being discovered by the defenders? Cao Yue couldn't think of it.

After asking for a confession, Cao Yue also had the two Jiannu killed, and comforted the frightened Han Chinese.

He told the Han people that the Ming army had defeated Jiannu at Songshan, and that it would not be long before Shengjing would be recaptured, and the Han people in Liaodong would no longer be oppressed and mutilated by Jiannu.

Cao Yue also asked them to distribute the weapons left behind by Jiannu, and told them to quickly find a safe place to hide after the other people left here, and then find a way to contact other Han people, and respond when the Ming army came.

These Han people, who were bullied by Jiannu and had seen too many tragic fates of their compatriots, all burst into tears when they heard what Cao Yue said. They believed what Cao Yue said, and the Ming army would soon open up here, and their fate changed from then on.

Seeing that these people were so excited, Cao Yue couldn't bear to kill them all on the pretext of avoiding their whereabouts being exposed.

After appeasing these Han people, Cao Yue immediately gathered several of his thousands of generals and generals to discuss countermeasures.

"Jiannu is very strict at night, and there is no way to deceive the city gate, so it can only be attacked during the day," Zhao Liang, the general manager of Qian, said helplessly.

"A strong attack will definitely not work, you must outwit it," Cao Yue denied what Zhao Liang mentioned, "If you want to break through Shengjing, you must find a way to deceive the city gate and capture the city gate at the minimum cost." As long as the city gate is breached, with the power of my more than 1,000 muskets, it is not a problem to solve thousands of Jiannu, old and weak soldiers. We have to figure out how to capture the city gates. ”

It's just that no one can think of how to approach Shengjing City in the daytime without realizing it.

At this time, the sergeant came to report that he was lurking in a secret post five miles away from this Zhuangzi and had captured three Jiannu who were delivering urgent news. As soon as he heard that Jiannu had been captured, Cao Yue immediately ordered several prisoners to be escorted over.

Naturally, it was another devastation, and Cao Yue used some of the methods he learned in his later life to interrogate the prisoners, and after tortured the three Jiannu into inhuman shapes, he finally asked for a confession. It turned out that these three Jiannu were the post guards who sent an urgent report back from Songshan, and they carried the urgent order of Emperor Taiji of the Qing Dynasty to return from Songshan. Cao Yue's subordinates searched for an urgent report from Jiannu's package, and asked the two sergeants who knew Manchu to study it repeatedly, and finally understood the content.

It turned out to be Matsuyama's battle report. The battle report said that the Qing army defeated the Ming army under Songshan City, the Ming army suffered heavy casualties, the remnants retreated to Songshan City, and the rest of the men and horses were all annihilated. The war report did not mention that Jiannu was hit hard by the Ming army in Ru* Fengshan, and the Ming army counterattacked and killed in the imperial tent of Huang Taiji.

After reading the battle report and interrogating them harshly, Cao Yue also asked the three Jiannu to be disposed of.

At this time, he had already made a new, very bold decision. While continuing to discuss the arrangement with the main backbone of his subordinates, he also expressed his bold idea.

"Everyone, Jiannu quickly sent the battle report back to the city, we already know the way they called to open the city gate, Jiannu's battle report and the letter they brought were all captured by us, and I will believe that they are not lying," Cao Yue's very resolute gaze swept over the people in front of him one by one, and then said in a deep voice: "Therefore, the general decided to choose one person, with a few soldiers who can speak Manchu, when most of our army sneaked outside Shengjing City, call to open the city gate at night, use the fire to kill the city gate guards, and wait for the city gate to open, The rest of the horses took advantage of the chaos and went into the city. ”

Then Cao Yue also talked about his plan in detail. When they broke out of the encirclement, their sergeants carried a musket and three times the standard amount of ammunition. Neither these muskets nor ammunition were used, and Cao Yue planned to concentrate some of the ammunition and make it into a large explosive pack. He ordered several sergeants who could speak Manchu to disguise themselves as Jiannu's post guards to deliver emergency military information, trick them into opening the city gate, and when the city gate was opened, these sergeants rushed in, set off explosives, killing and injuring the guards at the city gate, preferably blowing the city gate to pieces.

In advance, the men and horses he personally led took advantage of the darkness to sneak to the city of Shengjing, and waited for the post guard who pretended to deliver urgent news to open the city gate, and after the attack was successful, he took advantage of the situation to kill and occupy the city gate. As long as the city gate is occupied, then the follow-up men and horses can be killed, with the thousands of old and weak soldiers of Jiannu, it is difficult to resist the attack of more than a thousand elite Ming cavalry when it is dark and cannot see clearly.

If the deception of the city gate is unsuccessful, or there is no way to succeed, then Cao Yue can also lead the rest of the horses to retreat and escape from Shengjing, at most the loss of the sergeants who deceived the city gate.

After listening to what Cao Yue said, everyone felt that this plan was too risky, if they couldn't open the city gate, the plan would fail, and their surprise attack could only be in vain. However, they couldn't think of a better way, and finally had to agree to Cao Yue's proposal.

Cao Yue also slapped the board very simply, and immediately asked everyone to prepare urgently.

From the interrogation just now, it was learned that when Jiannu sent the emergency military information, there were two to five sergeants accompanying him, that is, at most, five sergeants could be disguised as Jiannu post guards to call the city gate. As long as the five sergeants cooperate properly, when the city gate is opened, they can attack successfully. Cao Yue handed over this very difficult task to Cao Qian, a general of his own army.

Cao Qian was young, less than twenty-five years old, very clever, very skilled, very brave, and quite steady, Cao Yue felt that only Cao Qian could complete this task. He personally called Cao Qian to his side and solemnly handed over this task to the other party.

Cao Qian did not hesitate or prevaricate, took over the task happily, and said some of his thoughts.

After the two discussed, Cao Qian also immediately made preparations. Two Manchurian sergeants, plus two of Cao Qian's right-hand men, were selected to disguise themselves as Jiannu sergeants to call the city gate. General Cao Yue personally led the rest of the horses and sneaked to the city of Shengjing.

After everything was properly arranged, Cao Yue immediately ordered the sergeants who had been resting for a while to gather and prepare to act overnight.
