Of the four squad leaders of the Army Lecture Hall, only Zheng Chenggong was left, and he was also the most anticipated student of the crown prince Zhu Cihong, a tactical and ideological elaboration.

Because Zheng Chenggong is one of the young generals most respected by Mr. Zhu Shun, the other is Cao Bianjiao, who has made many military exploits.

Cao Bianjiao can take over the banner of the governor from Sun Chuanting, and Zheng Chenggong, who is still a teenager, doesn't know how many strategies he can be so valued by Mr. Zhu Shun.

Zheng Chenggong stood up and walked in front of Zhu Shun, Prince Zhu Cihong, and Lu Daqi: "Qiyu Mountain Chief, student Zheng Chenggong requests tactical deduction. ”

The crown prince Zhu Cihong glanced at Mr. again, and Mr. still had a calm face that made people guess his thoughts, nodded and said, "Begin." ”

Zheng Chenggong's little face was a little more solemn: "After the student read the newspaper, he found an extremely serious problem. ”

Although Zheng Chenggong is young, his talent has been unanimously recognized by the students of the Army's Martial Arts Hall.

Just when everyone was full of expectations, expecting Zheng Chenggong to say something far-sighted, but a nonsense came.

Zheng Chenggong paused, as if trying to suppress the emotions in his heart: "The Manchu Qing Dynasty has prepared enough grain and grass to carry the weight. ”

Laipin has just mentioned that the three armies have not moved the grain and grass first, this is a common sense that only the general banner in charge of hundreds of people understands, and the common people understand the principle of eating.

The Manchu Qing gathered an army of 150,000 to attack Shanhaiguan, and if they did not prepare sufficient grain and grass, would they watch all the 150,000 troops starve to death.

If this sentence was heard by the border generals, they would have looked down on the army martial arts members as a group of scholars and military attachés, and they would definitely scold a lot of words.

If the soldiers don't have food to eat, it's already good to not be in the camp, where is the strength to fight the Manchus.

I don't understand this truth and still read military books, and no matter how much I read the art of war and tactics, I only trained a group of Zhao Kuo who talked about soldiers on paper.

There are examples of recruitment, and the crown prince Zhu Cihong believes that Zheng Chenggong, who is most valued by this gentleman, will never open his mouth at this time, and should have his unique opinions.

Zheng Chenggong didn't care about anyone's opinion, but his little face became more and more solemn: "The student dared to ask the mountain chief a question. ”

"Starting from the Xiongnu in the Han Dynasty, why do the northern nomads pull up a large army to attack our Central Plains Dynasty as long as it is winter."

There are many answers to this question, for gold and silver treasures, for women, and so on, but add a winter to this sentence.

The crown prince Zhu Cihong somewhat understood: "Grain." ”

Zheng Chenggong's small face nodded solemnly: "Yes, it's just for food, which is also the fundamental reason why it is difficult for the northern nomads to become a big climate." ”

"You should have heard the 400 mm precipitation line from being told by the industrial marquis, and you know that grain has always been the root cause of the difficulty of the northern nomads from becoming a real henchman."

"Food is scarce, resulting in a limited number of people who can feed, and every year in winter because of the reduction of pasture grass, there are even fewer people who can be fed, so they can only go to the Central Plains Dynasty to grab food."

"But in the battle report released by the mountain chief, although it was mentioned in a very inconspicuous place that the Manchus had prepared sufficient grain and grass, it meant one thing."

Zheng Chenggong suddenly held his breath and said with difficulty: "The Manchu Qing Dynasty is no longer short of food. ”

There is no shortage of food, which makes everyone realize the seriousness of the situation, so serious that the Ming Dynasty has really reached the point of destroying the country.

Because of the restriction of the 400 mm precipitation line, throughout the history of the Central Plains for thousands of years, there has never been a record of the northern nomads directly laying down the Central Plains Dynasty.

Even Yuanmeng first unified the entire steppe until Taixi after Genghis Khan first conquered the territory of the Central Plains Dynasty, and finally conquered the Central Plains Dynasty with the efforts of his grandson Kublai Khan.

Others, whether it is the Xiongnu of the Han Dynasty or the Hui and Tubo of the Tang Dynasty, have always been just a big trouble for the Central Plains Dynasty, and they have never completely conquered the entire Central Plains.

Even in the Song Dynasty, which abolished its martial arts, the Jurchens were only a big trouble, and they persisted in Jiangnan until the Jurchen fell.

The edifice of the Central Plains Dynasty began from within, with corrupt officials running rampant, serious land annexation, and poor livelihood.

Today's Ming Dynasty is on the verge of the building will fall, even more than other dynasties, and the officials and gentry of the Ming Dynasty do not accept food.

Zheng Chenggong analyzed from a subtlety that was insignificant and would not even be cared about, and analyzed that the Manchu Qing Dynasty was no longer short of food, and was free from the shackles of the 400 mm precipitation line.

Everyone present understood why Zheng Chenggong was so serious, originally because the Donglin Party was fighting for power and profit, there were many military leaders, and the Ming Dynasty was already on the verge of collapse.

The Manchu Qing Dynasty is no longer short of food, and the Ming Dynasty may not be far from its fall.

Seeing that the atmosphere in the general staff room of the war was getting more and more wrong, Zhu Shun suddenly interjected: "What do you think about this matter." ”

Zheng Chenggong peeked at Zhu Shun who was sitting on the official hat chair, and muttered in his heart that it is difficult for the industrial marquis to be a fairy, how can I see through that I already have a plan to deal with it.

In addition to a huge sand table, there is also a map of Wanguo Kunyu, which occupies an entire wall, and is an accurate world map drawn under the guidance of Zhu Shun.

Zheng Chenggong walked over, picked up a long bamboo pole, and pointed to Beihai Lake above the map of Wanguo Kunyu, Beihaier Lake in the mouth of the Manchu Qing Dynasty: "This is the granary of the world of the Manchu Qing Dynasty, and it is the place where the Manchu Qing Dynasty mainly grows potatoes." ”

"As long as we follow the example of Fan Wencheng's evil deeds committed in Beizhili and scatter a large amount of lime on the land of Beihaier Lake Province in the Manchu Qing Dynasty, this problem will naturally be solved."

After saying this, all the students of the Army Lecture Hall also fell into deep thought, and none of them fell into cheers because of the cleverness of a strategy.

All the students took out paper and pencil and used some known data to make actual calculations, and the more they calculated, the more sad they became.

Zheng Chenggong's strategy has been out of the scope of tactics and has reached a strategic point, but it is extremely difficult to implement.

Beihaier Lake is very far away from the Daming border pass, and the communication line is not familiar, how to cross the Manchu blockade to reach Beihaier Lake is a big problem.

The number of this army cannot be less, not to mention that the number is small, it will not be able to resist the attack of a large number of Manchu cavalry, even if it is sprinkled with lime, there is not enough manpower.

The Manchus were able to destroy the fertility of all the upper and middle fields in Northern Zhili in a short period of time, because there were ordinary people who cultivated these lands for the Manchu Qing to drive.

There were indeed many Manchu people near Beihaier Lake, but they were all nomads who were skilled in bows and horses, and they could escape on horseback and couldn't catch up.
