On the second day after the acting king Zhu Chuanqi asked Cao Yue to no avail, Wang Chengen, who received the will of Emperor Chongzhen and went to Datong with Chen Xinjia, the secretary of the military department, to investigate the murder of Wu Ming, the deputy commander-in-chief, also arrived in Datong.

During the Ming Dynasty, the power of eunuchs was unimaginable. This was especially true when Emperor Chongzhen was in power, he was suspicious by nature, and he didn't dare to believe too much in the ministers and generals, and the people who believed most were the eunuchs around him.

When Chongzhen was around, there were four very trusted insiders around him, namely Cao Huachun, Wang Chengen, Gao Qiqian, and Wang Dehua.

Cao Huachun was Emperor Chongzhen's most trusted eunuch, and was authorized by Emperor Chongzhen to handle Wei Zhongxian's case with full authority, and to rehabilitate Zhaoxue's more than 2,000 cases of Wei Zhongxian's unjust, false and wrongful cases. Because of his ability to do things, he won the trust and reliance of Emperor Chongzhen, and was later promoted to the eunuch of the ceremonial supervisor Bingbi and the governor of Dongchang, Wang Chengen, Gao Qiqian, and Wang Dehua were also the eunuchs of the ceremonial supervisor Bingbi.

At the end of the eleventh year of Chongzhen, Cao Huachun, the governor of Jingying Rongzheng, begged for leave due to illness and sent three orders to Emperor Chongzhen. In February of the twelfth year of Chongzhen, Cao Huachun was allowed to take leave and return to his hometown. After Cao Huachun returned to his hometown on leave, Wang Chengen became the most trusted eunuch of Emperor Chongzhen.

During the Ming Dynasty, the eunuchs of the celebrant eunuchs had the positions of admiral, palm seal, bingbi, and court, and they were very powerful. In the Ming Dynasty, the cabinet and the ministers of the ministries discussed the "vote draft" in advance, and the cabinet members drew up opinions on the handling of the matter, which were written in blue pen. After submitting it, the emperor was asked to approve it, because the emperor used a red pen for approval, so it was called "approving red", but most of the emperors in the middle and late Ming Dynasty were lazy with political affairs and abandoned the government, so the power of "approving red" fell into the hands of eunuchs.

The eunuch who is the celebrant is responsible for using the red pen to indicate whether the opinions can be implemented, and has great power. Although Wang Chengen is not as good as Cao Huachun in his position, he does not have the position of commander and palm seal, but there are no other eunuchs in the palace who are more trusted by Emperor Chongzhen, and the affairs of the celebrant are basically in charge of Wang Chengen, and he has faintly become the head of the eunuchs.

This is also the main reason why in the original history, when Li Zicheng led the army to break through the city of Beijing in the seventeenth year of Chongzhen, Wang Chengen was finally awarded the governor's affairs in Beijing, and finally accompanied Emperor Chongzhen to hang himself in the coal mountain.

Wang Chengen's power is known to everyone inside and outside the court, and no one knows it. Hearing that Wang Chengen personally led people to Datong to investigate the military situation, Datong Town Supervisor Zhang An and Wei Daben were all shocked. They knew what the purpose of Wang Chengen and Chen Xinjia was when they came to Datong, and they were faintly worried that Cao Yue was in trouble this time.

After receiving the news, Wei Daben, Zhang An and Cao Yue all went out of the city for ten miles. Zhu Chuanqi, the acting king, also went out of the city to greet him, and Zhu Chuanqi, who knew the reason for Wang Chengen's coming, looked at Cao Yue with a gloating look, and he didn't even greet Cao Yue.

Cao Yue didn't bother to pay attention to it, and stepped forward to greet him very politely, with a look of neither humility nor arrogance.

After some greetings, everyone got into the car and sat in a sedan chair, or rode back to Datong City together.

Wei Daben, the prefect of Datong, held a banquet in the prefect's mansion to welcome Wang Chengen and Chen Xinjia.

At the banquet, without waiting for Wang Chengen and Chen Xinjia to take the initiative to ask anything, Cao Yue took the first step to tell all the information about the situation of Duoduo leading the army to attack together. In this battle under the city of Datong, the Datong army not only eliminated thousands of Jiannu, but also captured a lot. Among the captives were Han army officers, as well as Mongol nobles and Jurchens.

After passing the interrogation, Cao Yue also learned more about the situation, and basically figured out the purpose of Duoduo's southern expedition. And he didn't tell Zhang An and Wei Daben about these things, and he didn't report them to the court for the time being.

After saying these things, Cao Yue said with emotion: "Chen Shangshu, Wang Gonggong, I didn't expect that this time Jiannu would come with such a purpose, and the attack on Datong was to take revenge for the enemy who led the army to break Shengjing that day, and also wanted to spread rumors in the unfavorable situation of attacking the city, and remove the lowly position by the hand of Long Live Banzai, they have sinister intentions." During this time, the lowly officials in Datong arrested a lot of people who had collusion with Jiannu and Liukou, and even after Jiannu was defeated, these people spread rumors and slandered the lowly positions, and also asked Chen Shangshu and the prince to investigate and clean up. ”

Cao Yue's preemptive explanation immediately made some people understand his meaning, if after he led the army to a great victory this time, the imperial court would still investigate his guilt, it would be exactly the discord of Jiannu. In this way, it seems that Emperor Chongzhen is an imbecile, and he can't even distinguish such a simple discord meter.

Zhu Chuanqi, who originally wanted to take the opportunity to report Cao Yue, was suddenly dumbfounded. If Cao Yue said this, he also stood up and accused, saying that Cao Yue had the intention of rebellion, didn't he just fall into Cao Yue's trap and become a slanderer?

Wu Ming was killed, Cao Yue, Zhang An, and Wei Daben have already explained in the report, and today Cao Yue explained the matter again, and asked the deputy general Zhao Tai, the deputy general Gao Gao, Zhu Yang, and several other generals to testify.

Gao Gao and Zhu Yang had already stood firmly in Cao Yue's trenches, and they also told Wu Ming that he wanted to pull them together, frame Cao Yue, and replace them. On the same day, Wu Ming led the army to battle, and he also talked about the enemy's cowardly escape.

Without waiting for Wang Chengen and Chen Xinjia to say anything, Cao Yue explained too much of the situation they wanted to investigate in public, and found a lot of witnesses, and asked Zhu Chuanqi and others who wanted to be unfavorable to him to shut their mouths. This shocked Zhang An and Wei Daben, this young man is really powerful, preemptively explained these things, attributed everything to Jiannu's discord plan, and even implied that Wu Ming's cowardice was in collusion with Jiannu, they knew that Cao Yue would definitely be able to survive the investigation without danger this time.

After thinking about the matter, they also stood up and helped Cao Yue speak, praising Cao Yue's actions in Datong, especially when Jiannu attacked this time, he was calm and decisive, and finally defeated Jiannu outside the city and won a big victory. If there is no Cao Yue, today's Datong may still be at war, although Jiannu may not be able to break through the city, but countless people will die in the war, and the displaced people are everywhere. Jingshi may also be besieged by Jiannu, and the Ming will encounter great difficulties.

However, Wang Chengen and Chen Xinjia are both scheming people, and they did not express their position immediately, but said that the main purpose of their visit to Datong this time was to reward Cao Yue on behalf of the imperial court, to comfort the meritorious soldiers, and then to understand the situation of this battle clearly. Wu Ming impeached Cao Yue for having the intention of rebellion, although the emperor did not believe that Cao Yue had this intention, and they also believed that Cao Yue was loyal to the country, but they still had to investigate, and everything would be determined after the investigation was clear, and they would return Cao Yue to an innocent person.

Wang Chengen and Chen Xinjia refused Wei Daben's intention and did not live in the prefect's mansion, but in the post house.

After returning to the post house, Chen Xinjia discussed the matter with Wang Chengen alone.

Drinking tea, Chen Xinjia said slowly: "Princess, Cao Yue must have expected that the imperial court would send someone to investigate whether he had plotted rebellion and killed Wu Ming, and he had already made preparations, it seems that we can't find out anything this time!"

Wang Chengen also drank tea leisurely, "Chen Shangshu, we are running an errand for Long Live Lord, we just need to do the errand well, investigate the matter clearly, and let Long Live Lord rest assured." How to deal with Cao Yue, Long Live Lord has his own fixed number, let's not worry about it!"

Chen Xinjia, who was old and treacherous, immediately read the special meaning from Wang Chengen's words.
