The benefits of Emperor Chongzhen's leaving behind the Manzhu ritual are obvious, not only to break the alliance between the Horqin people and the Jurchens in the future, but also to leave a lot of benefits in the near future.

Since Manzhu Xili went to Shenyang City in the autumn and winter of the first year of Chongzhen, and reported to Huang Taiji that the left wing of Horqin had failed to conquer Karaqin because of the surprise attack of the Ming army on the land where he was stationed, he was left by Huang Taiji in the Khan palace in Shenyang, and stayed by Huang Taiji's side as a guard.

This time, he was ordered to follow Huangtai Jixi to conquer Har, and then went all the way south to the city of Huailai.

Therefore, this Manzhu ritual is almost equivalent to participating in the whole process of Huang Taiji's conquest of Chahar and the planning and implementation of the attack on the hinterland of Datong in the Ming Dynasty.

He has a considerable degree of understanding of the internal situation in the country today, the current situation of Chahar, and the itinerary and arrangement after the Jianyu entered the customs.

Although it cannot be said that everything is clear, every aspect is inseparable.

And since Emperor Chongzhen left him, of course he would not put such a good resource and not use it.

First of all, he asked the envoy of the Imperial Court to be respectful to Hou Wu Weiying and the staff of the Ministry of War, Shi Lang Zhongniu Juming, to accompany him to wander around the east, west, north and south of Juyong Pass, and not hide anything from him.

Then he provided him with convenience, and asked him to tell the two Horqin Mongols who had taken Du Xun to Huaihuai about what he had seen in Juyong Pass, and they would send the so-called information back to Huang Taiji's camp.

In particular, the news that Emperor Chongzhen himself and the important ministers around him were in Juyongguan were passed back.

Among them, the role that the Manzhu ritual can play is not comparable to any other person.

And when tens of thousands of Jianyu troops and Mongolian servant troops came to attack Juyong Pass, Emperor Chongzhen also specially asked people to bring Manzhu Xili to his side and watch the battle with him at Yongshengmen.

This battle not only caused the Jianlu and Mongol armies who tried to storm Juyong Pass to return with heavy casualties, but also made Manzhu Xili, a young man from the depths of the steppe, deeply shocked, and began to think about the fate of the Horqin people for the first time in his life.

It was also after the bloody battle of Juyongguan that Manzhu Xili was no longer secretly unwilling to answer various questions from Wu Weiying, the envoy of the Imperial Court of the Imperial Court, and Niu Juming, the staff of the Ministry of War, but suddenly became omniscient, and said everything he knew and heard in one go.

Soon, what happened after Huang Taiji entered Kuku and Tun, as well as Huang Taiji's various arrangements since then, and even the various roles played by traitors such as Fan Wencheng, Ning Wan and Fan's merchants, were all written into detailed reports by Wu Weiying and Niu Juming and sent to Emperor Chongzhen.

Emperor Chongzhen was of course very happy to get such a report.

Jianyu's entry from the killing of Hukou this time is something that has not happened in the original history, and many of the inside information and arrangements, even if this Chongzhen Emperor is a traveler now, it is completely black-eyed.

In the original history, a few years later, the Jianyu army did penetrate into the hinterland of the Ming Dynasty from places such as Hukou, Victory, and even Dushikou, and it seems that it was more than once.

Because in the original history, after Jianlu drove out Lin Dan Khan of the Chahar Department, he occupied Monan and subdued the Monan Ministries, and since then, Shanxi, Datong, Xuanfu and Jianyu are only separated by a wall in Monan, which can be said to be close at hand.

As long as there is a little wind and grass in the Ming Dynasty, such as the rebellion of thieves and the like, the Jianyu will gather outside the border, and then break through the border at the right time.

On the Ming side, it is both tired of guarding and completely unable to prevent it.

This is also the reason why Emperor Chongzhen attaches so much importance to the Mo Nan issue this time.

And Kuku and Tun or Naturalized City are to Datong and Xuanfu, just like Rehe Fort is to Jizhen and Jingshi, once they are in the hands of Jianyu, then the direction of the north of the Ming Dynasty will be full of loopholes and smoke.

Therefore, from the various information leaked by Manzhu Xili, after Emperor Chongzhen learned of Huang Taiji's relevant arrangements, he wrote several handwritten instructions again, and sent his close attendants to Yanmen Pass and Huamachi to meet Li Banghua, Yuan Chonghuan and Sun Chuanting.

First, he told Li Banghua to send troops to annihilate the enemy in Shuozhou as soon as possible, and then get in touch with the governor of Datong and the general army, and encircle the remaining army of Huang Taiji and others in the pass as much as possible.

Second, tell Yuan Chonghuan not to deliberately intercept Lin Dan Khan's westward migration of the troops under the command of the governors of the three sides in Ningxia and Gansu towns.

As long as Lin Dan Khan did not take the initiative to attack the Ming army, he would let them move west to Qinghai.

At the same time, it was necessary to mobilize the troops of several towns under his command to deal with the Abatai troops and the Mongol soldiers who were chasing Lin Dan Khan.

At the same time, Emperor Chongzhen also asked Li Banghua and Sun Chuanting to pay attention to the thieves in Luya Mountain in the northern section of Luliang Mountain when they went north to pursue Jianlu and the Mongol soldiers, and did not let them go out of the mountains and enter the hinterland of Shanxi.

On the morning of November 20 in the second year of Chongzhen, Emperor Chongzhen made some arrangements for the battle situation on the front line of Xuanda, and immediately ordered Ma Shilong and Qian Yuanyu to lead a total of 16,000 men and horses in the five standard 16 battalions of the first town of the Guards, carrying guns, ammunition and a large amount of grain and grass, singing the original Ming military song of Qi Jiguang, and leaving Juyong Pass.

"All of us are united, and the mountains can be shaken. Only loyalty and righteousness, angry bullfighting!

"The Lord will kiss me better than my parents. Committing military law is not free!

"The order is clear, and the reward and punishment letter are written. Go to the water and fire, don't stay late!

"Report to the Son of Heaven and save the head of Qian. Kill all the thieves and slaves, and find a marquis! ”

If an army does not have a military song, then it is difficult for the army to have spirit.

The army of the Ming Dynasty did not have a unified and clear military song of the imperial court, but in different historical stages, there were indeed things similar to military songs.

At the beginning, the predecessor of the Ming army was the Red Turban Army under the command of Zhu Yuanzhang, Taizu of the Ming Dynasty.

"The wind is from the dragon, the cloud is from the tiger, and the dust and earth are fame.

"Looking at Shenzhou, the people are suffering, and thousands of miles of fertile land are barren.

"Look at the world, as much as you want, the way of heaven is broken and the husband makes up for it!

"Good boy, don't be parents, just for the common people, not for the lord.

"Ninety-nine with a steel knife, kill all Hu Erfang's handles!

"I am a dignified man, what is a horse and a cow for a Tartar!

"The strong man drank all the wine in the bowl, and he did not look back on the journey of a thousand miles.

"The golden drums are roaring in unison, and the yellow dragon will not be broken!"

When Zhu Yuanzhang issued a statement to discuss Meng Yuanyu, with Xu Da as the general and Chang Yuchun as the deputy general, when he swore to the Northern Expedition from the south of the Yangtze River, the Ming army at that time sang this military song and marched forward to capture the capital.

It's just that after Ming Taizu pacified the world, Zhu Yuanzhang was very secretive about his past when he joined Mingjiao as the general of the Red Turban Army, and the Red Turban Army gradually became a taboo topic.

And this military song, which inspired countless Han people in the Central Plains to resist the oppression of the Meng Yuan, also disappeared in the Ming army.

As for what kind of military songs were popular in the Ming army after this military song, it is unknown.

Until one night in the forty-first year of Jiajing, Qi Jiguang led the Qi family army to defeat the Japanese and returned, the soldiers fought hard again and again without rest, Qi Jiguang wanted to reward the whole army on the way to victory and there was no wine and meat, so he improvised a poem with an ancient style, called "Triumphant Song", teaching the soldiers of the whole army to sing together, and using military songs instead of wine and food to boost the morale of the whole army.

This "Song of Triumph" was quickly sung in the front-line army fighting against the Japanese in the coastal areas of Fujian, Zhejiang and Guangdong, and later it was introduced to the northern army with Qi Jiguang's transfer to Shanhaiguan and Jizhen border passes.

Although Qi Jiguang's "Triumphant Song" is not clearly the military song of the Ming Dynasty, it has the same status as a military song, and at the end of the Ming Dynasty, in the armies of the north and south, all the troops who pursue the training method of the Qi family army are still singing.

At the beginning, when Emperor Chongzhen made up his mind to organize and train a new army, he had been thinking about finding a rousing military song for the future army of the Ming Dynasty.

Of course, there are many such songs in later generations.

But after thinking about it, I don't think it's appropriate to use any song in this era.

Speaking of which, the most suitable is Yue Fei's "Man Jianghong".

It's a pity that he doesn't know what Man Jianghong's ancient tunes are.

And his special status as the emperor made him have no way to go to the army to teach the only song he is familiar with, "Loyal to the Country".

In the end, Emperor Chongzhen asked Mao Yuanyi, who was familiar with the story of the Ming army's regulations, and Mao Yuanyi immediately recommended Qi Jiguang's "Triumphant Song".

After seeing this song of Qi Jiguang's triumph, which had been widely sung in the army, Emperor Chongzhen changed it to two words, changing the "dare to stay late" to "Mo Chi Liu", and the last "Japanese slave" to "thief slave", and then temporarily set it as the military song of the Guards.

On the morning of November 20 in the second year of Chongzhen, Emperor Chongzhen took the civil and military officials accompanying him, stood on the gate of the northernmost military capital of Juyong Pass, and witnessed more than 16,000 people in the first town of the Guards singing this triumphant song of Qi Jiguang out of Juyong Pass in unison, stepping on the ice and snow to march towards the northwest, and for a while I couldn't help but feel a lot of emotion in my heart.
