Jiannu retreated from the city of Beijing, and the officials in the court also breathed a sigh of relief.

Especially Chen Xinjia, the secretary of the military department, he knows best the combat effectiveness of the soldiers of the Beijing camp, and it is unknown whether he can resist the siege of Jiannu. Now that it's okay, Cao Yue won a big victory in Datong, and directly scared away Jiannu who was about to attack Beijing City, which made him breathe a sigh of relief, and he couldn't help but be grateful to Cao Yue.

However, many ministers in the court did not approve of Cao Yue's military exploits, and they almost ignored Cao Yue's record of almost annihilating Geng Zhongming's troops under Datong City, and only focused on Wu Ming's report and Cao Yue's unauthorized killing of Wu Ming. Also, when Duoduo retreated, there was still information left, that is, the Ministry was able to hit Beijing, thanks to Cao Yue's release. Duoduo's information caused them to immediately connect with Wu Ming's secret report, accusing Cao Yue of colluding with Jiannu, and that Duoduo's army was able to reach the city of Beijing because of Cao Yue's connivance.

They also accused Cao Yue of killing Wu Ming, the deputy commander-in-chief, in order to cover up his misdeeds. Some Qing factions, including Liu Zongzhou, have impeached Cao Yue and demanded that the imperial court immediately issue an order to arrest Cao Yue and put him in prison, so as to prevent changes in Datong.

However, there are also ministers who strongly support Cao Yue, saying that this is a false accusation made by Wu Ming under jealousy, and the information left by Jiannu is just a very low-level divisive scheme, and they can't beat Cao Yue, so they want to use the discord to frame Cao Yue. They strongly suggested that the emperor send someone to investigate the matter, return Cao Yue to a clean slate, and suggested that Emperor Chongzhen give Cao Yue a greater reward to encourage the morale of the Ming soldiers.

Supporting Cao Yue in the court were the first assistant Zhou Tingru and the military secretary Chen Xinjia, who originally had different political views from Liu Zongzhou and other Qing schools, and often had disputes. The so-called enemies of the enemy are friends, and they don't appreciate Cao Yue much, let alone agree with Cao Yue's military exploits, but just use Cao Yue and Liu Zongzhou to artificially attack political enemies.

Emperor Chongzhen was very happy to see the two factions in the court and the Chinese faction quarrel because of Cao Yue, in fact, he knew very well that Cao Yue could not have the heart of rebellion, the reason is as Wang Chengen said, Cao Yue went to Datong for such a short time, it is too unrealistic to want to stand on his own or rebel, if he waits for another two years, others say so, he will believe it.

Wu Ming is an imbecile, in order to retaliate, he even made false accusations, and he is really innocent.

Emperor Chongzhen was already thinking that in addition to being soft and hard to Cao Yue, it would be better to send someone to Datong to be Cao Yue's deputy, so that he could not only have a good relationship with Cao Yue, but also restrain the young chief military officer.

After listening to the debate between the ministers of the two factions in the court and China on the Cao Yue issue, Emperor Chongzhen made a decision and sent Wang Chengen, the eunuch of Bingbi, and Chen Xinjia, the secretary of the military department, to Datong to investigate the matter.

How to deal with Cao Yue, everything will wait for the results of the investigation.

This investigation not only needs to find out whether Cao Yue has conspired against him, but also to investigate whether Cao Yue's victory in Datong has any water.

Of course, Cao Yue didn't know what was happening in Beijing, but he sent people everywhere to find out the movements of the Qing army, and those sergeants with the best skiing skills were sent out to track the movements of the Qing army.

After the Qing army withdrew from the city of Beijing, he quickly received this information and was greatly relieved. It seems that Duoduo still has some scruples and does not dare to let go of the city of Beijing.

Jiannu retreated, and there was nothing to do with him, so he continued to train and waited for information from Beijing.

After re-establishing slaves under Datong City and achieving a brilliant victory, Cao Yue felt that Emperor Chongzhen would definitely give him a little reward, and he hoped that the reward from the imperial court would make him pay less. Soldiers who have made meritorious contributions this time must be rewarded, those who have died in battle must be compensated, and those who are injured must also be given condolence money. If the court does not have rewards in terms of money and goods, then these must be paid by him privately.

Of course, this is a large amount of money, and it must be a bit painful to take it out of your own pocket.

－－－－－－－－－－－－

"Red girl, Cao Yue actually defeated Jiannu under Datong City, and the Ming army still went out of the city to meet it, this is too unbelievable!" In the Yuelai Inn, several rogues were standing around the beautiful young woman in red, whispering about the situation they had found in the past few days. The focus of their speeches mainly revolved around the battle between the official army and Jiannu under the city of Datong, which had just ended a few days earlier.

Originally, they thought that this would be a very difficult and long-lasting battle to defend and siege the city, and they once regretted that they did not take advantage of the chaos before the attack of Jiannu to get out of the city, so that the whole city was on alert, no one could go out of the city, and they couldn't get out, delaying the trip, and danger could come at any time. But I didn't expect that the battle ended in less than a day, and the final result was that the official army defeated Jiannu, and nearly 10,000 Jiannu who attacked under the city of Datong were almost wiped out, and the official army achieved such a brilliant record at almost no cost, which made everyone's jaws drop.

It is precisely because such a result is so shocking that many rogues, including the leading "Red Girl", no longer plan to leave immediately, but want to reconnoiter the strength and deployment of the Datong army.

They had to figure out how Cao Yue used to defeat nearly 10,000 Jiannu without blood.

However, most of the people who were fortunate enough to watch the battle at the head of the city that day were high-ranking officials of Datong City and Cao Yue's cronies, and Cao Yue also had a strict order not to pass on the tactics of the first battalion to the outside, and those who violated military law were involved. Therefore, except for the soldiers in the army, the people in the market basically did not know how Cao Yue defeated Jiannu.

Because it is not clear what method Cao Yue used to defeat Jiannu, various legends have arisen.

Some people say that Cao Yue had the courage of ten thousand people, and he killed the Jiannu array alone, beheaded hundreds of people, and finally Jiannu fled without defeat; Some people also say that Cao Yue used a scheme to lure Jiannu into a scheme and finally defeated them, but there are many theories about what stratagem he used. It is also said that Cao Yue created super powerful weapons, and he used these weapons to defeat Jiannu.

These spies of Liukou did not find out the exact news, and the leading "Red Girl" did not personally investigate the situation because she had too many scruples, so she could not determine how Cao Yue defeated Jiannu, and this was something they had to know about this trip.

After listening to the reports of her subordinates, she finally made up her mind to investigate the matter in person, and went to the Chinese army camp where Cao Yue personally sat to investigate. When the subordinates heard that the "Red Girl" was going to inquire about the situation in person, while being ashamed of their incompetence, they also strongly advised the "Red Girl" not to take risks, because if something went wrong, it would be troublesome.

However, the "Red Girl" ignored the persuasion of her subordinates and insisted on going to investigate the situation herself.

The righteous army led by Li Yan was ready to join forces with Liu Zongmin's men and horses to attack Datong after the New Year.
