The Ming Dynasty started with caution

"Lord Yan has such good stuff, but you didn't bring it out early. You only told me after the baggage was sent to Yansui." Qin Hong felt that this kid was hiding his incompetence.

Before Zhu Hui, the Duke of Baoguo, went to fight in the northwest, the Ministry of Revenue was allocating military rations.

This kid didn't say a word, obviously wanting to leave it for his father to make merit.

Emperor Hongzhi nodded, and the cold smile on his face became more intense: "Mr. Yan, do you have any selfish motives?"

Selfish motives, of course.

However, when the memorials from the front were sent back, saying that there were too many baggage, Yan Chengjin thought of compressed biscuits.

The dry food eaten by the Ming army during the march and war was perforated biscuits.

The round biscuits were roasted on charcoal fire, crispy and salty, with small holes in the middle, and strung with ropes, and hung around the waists of soldiers.

Each soldier had a stack of them, enough to eat for more than ten days.

These biscuits were just enough to fill the stomach.

In contrast, compressed biscuits with a little brown sugar, salt and sesame oil are much more delicious, and only with strength can they be effective in combat.

And even perforated biscuits have to be baked one after another to replenish military supplies.

Compressed biscuits will not go bad after the battle, and can be stored for a longer time.

Yan Chengjin said seriously: "I have been thinking about ways to reduce the baggage. When I thought of it, the Duke of Baoguo was already in Yansui, not my fault."

"The Earl of Anding was transferred to Hetao, who will guard Xuanfu?" Liu Jian was worried about this.

"I think Wang Shi can defend Xuanfu."

Yan Chengjin turned over the cards of famous generals in the middle period of the Ming Dynasty in his mind and drew out Wang Shi's.

Wang Shi is not Wang Yue.

This person has an enviable talent, which is "talking about war on paper".

It's just that he hasn't been discovered yet, and no one knows that he is a talent.

Emperor Hongzhi and all the officials said that there were no generals available all day long, but in fact they lacked a pair of Bole's eyes, and these people were buried.

"Why do I remember that Wang Shi is a civil servant?"

Emperor Hongzhi frowned slightly and looked at Yan Chengjin.

Xiao Jing said: "Your Majesty is right. You appointed him as the Right Deputy Censor of Nanjing."

"Send Wang Shi to Xuanfu, and he will definitely be able to hold it." Yan Chengjin said decisively: "Dayan Khan and Huoshai are both in Hetao. We should worry about Hetao."

Huoshai is a Tatar leader.

If the little prince is not there, he will be the leader of the grassland Causeway Bay.

It's a pity that the plot of "If there is Yu, why is there Liang?" was staged. The little prince is too powerful and can only be a dog.

Whatever the eldest brother does, I will do.

"If Anding Bo can take back Hetao, I have no objection." Li Dongyang said.

Ma Wensheng said: "I have no objection."

Compared with Qin Hong, Emperor Hongzhi still believes in Ma Wensheng's vision. After all, he is an old soldier.

"Convey my order, Anding Bo will set off to Hetao, replace Baoguo Gong as the commander, and wipe out the Hetao invaders."

"Your Majesty, how can we suppress the invaders without a military commander? Will Shi Lin continue to stay in the army or be recalled to the capital?" Liu Jian asked.

Before Shi Lin left, he inquired about Fang Xue's investigation. Yan Chengjin didn't want him to stay with his father. There was a high probability that he was a bad teammate.

"Your Majesty, I think Chen Shou, the governor of Yansui, can take on this important task."

After recommending two people in succession, Qin Hong looked over. Your Majesty, is my position as the Minister of War fake? Is it also fake that the Ministry of War can control the world's troops?

"Your Majesty... Can I say something?"

"Qin Qingjia, please speak."

Qin Hong said: "I have no objection to Anding Bo leading troops to fight against the invaders, but Shi Lin is the censor of the Censorate, why should he be replaced?"

Replacing generals before the battle is a taboo in military strategy.

Shi Lin was the admiral in the army, and his importance was almost the same as that of the Duke of Baoguo.

If both of them were replaced, the morale of the army would inevitably be weakened.

Yan Chengjin said: "Before leaving Beijing, Lord Shi asked me about Fang Xue's trip to Yansui. It would be safer. I think it's better to replace him."

This kid actually said that Shi Lin was a traitor?

Emperor Hongzhi also thought it made sense and sent Fang Xue to Yansui to investigate the case. Why did Shi Lin ask this for no reason?

Qin Hong knew what Fang Xue was doing in Yansui.

This was a sensitive topic, so he didn't ask any more questions.

"Chen Shou is the governor of Yansui. He grew up in a military family. He understands military affairs. It's okay to send him as an admiral." Li Dongyang knew Chen Shou's background.

"Then appoint Chen Shou as the admiral."

"Thank you, Your Majesty!"

Yan Chengjin left the palace and ordered people to speed up the production of compressed biscuits, adding a few more pounds of salt and sugar.

If you want a horse to run fast, you have to feed it the best grass.

Wang Yue drew a map of Hetao, and based on his understanding of Dayan Khan, marked the possible route of the Tatars' march.

This time, Dad encountered the biggest challenge in his official career.

Dayan Khan and Huoshai were both in Hetao, and they were the strongest generals among the Tatars.

Searching for Tatars in Hetao, there is no wall as a barrier, and it will be a fight if you meet them.

"It is not convenient for me to go to Hetao, otherwise I will definitely go to help Brother Cangjin."

Wang Yue stroked his beard and sighed.

"This map is enough."

The Beijing army, which had been trained by Wang Shouren for more than half a year, has improved its combat effectiveness.

Yan Chengjin took the map to ask Zhu Houzhao for advice.

That's right... it's asking for advice.

...

Among the nine frontiers, Xuanfu is the closest to the capital, almost directly above the capital. The Tatars broke Xuanfu and went all the way south to the capital.

Yan Kesong soon received the imperial edict.

Let him take charge of the seal of the three armies and go to Hetao to fight the Tatars.

"Your Majesty, why are you going east and west?"

Just as he was wondering, the eunuch who announced the decree took out another letter.

"This is what Lord Yan asked us to give to you."

Yan Kesong opened the letter and saw that the handwriting was written by Cheng Jin. There were only a few lines of words:

Dad got fat again in the border area, right? Xuanfu is too comfortable. As the saying goes, you should think about women after food and clothing, right?

My son asked your majesty to find a job for my father to go into the river to fight against the Tartars. "

As expected, what he wanted was Cheng Jin torturing me...

Yan Kesong originally wanted to write books quietly, but he had a son who drove him to work hard and make progress.

He continued to read.

"My son asked his father a question: How should we deploy troops when we arrive at the Hetao?"

Yan Kesong hadn't thought about this issue yet. After thinking about it for a long time, he realized that Duke Baoguo's military experience was not inferior to his.

Even Baoguo Gong couldn't find a solution, what could he do?

I continued reading the letter, and sure enough I had the answer, but it was just a little irritating.

"I know dad can't guess it. I call it the nine-square grid tactic. Dad, please look at the map."

Yan Kesong dug into the envelope and found a map drawn on oil paper, only the size of letter paper.

This map is the topography of the Hetao.

The difference is that the map has a nine-square grid.

Just like the horizontal and vertical lines on a chessboard, they cover the entire map.

"The Tatars migrate in the Hetao and their whereabouts are unpredictable. If we place sentries at the grid points, we can quickly control their whereabouts."

The Tatars are always moving, and if you keep moving too, you won't be able to find them.

Divide the troops into small groups, like a net, and spread them among the rivers, and sooner or later the Tatars will be found.

Then use the sixteen-character formula.

The enemy advances and we retreat...

A small group can hold down the Tatar army and wait for reinforcements to arrive, and then they can kill them all in one fell swoop.

"Transmit my order and set off for Hetao."

Yan Kesong understood clearly.

This nine-square grid tactic is obviously intended to contain the Tatars from moving.

If the Ningxia border troops are mobilized, they might not be able to fight the Tatars.

…

"Your Majesty, this is Yan Chengjin's letter to Uncle Anding. I asked someone to rub a copy." Xiao Jing handed the letter over.

Emperor Hongzhi opened it and saw that it was a nine-square grid tactic?

"Summon Yan Chengjin."

A moment later, Yan Chengjin came to Fengtian Hall and bowed and saluted: "Your Majesty, Yan Chengjin, is here to see you."

"Did you come up with this Jiugongge tactic?"

You are shameless...

He secretly read the letters between our father and son.

Yan Chengjin secretly wrote down the name of the eunuch who delivered the message. No one has gone to Africa yet.

"I didn't come up with it, it was His Highness the Crown Prince who came up with it."
