Fengtian Palace,

Emperor Hongzhi and the Nine Ministers stood in front of a huge sand table with their hands behind their backs.

"It seems that the Tatars can send 50,000 troops to Datong, and they are determined to attack the city."

Dayan Khan's troops were at most 150,000, and their large troops were stationed in Hetao and played against Yan Kesong.

"Your Majesty has something unknown. After Dayan Khan got the three great generals of the Bian Barbarians, he went north to recover the tribes. Now the Ordos tribe, the Tumote tribe and the Yongsebu tribe have completely surrendered to Dayan Khan's subordinates."

Qin Hong analyzed the information in his hands.

The army that Dayan Khan owns is far more than the 150,000 troops that were originally 150,000.

In this way, other important towns on the Jiubian cannot mobilize troops to support Datong.

"Thirty thousand troops are fighting against 70,000 troops. Even if Wang Yue goes, he is afraid he will not be able to compete.

Not to mention, the border troops in Datong are not good at riding and shooting, and are far inferior to the iron tools of Tatars and Jurchens."

Ma Wensheng was blunt and did not talk nonsense just because the Datong border army was a soldier of the Ming Dynasty.

"If Yan Chengjin had not advised to attack Jianzhou, the Jurchens would not have joined forces with Tatars," said Qin Hong.

Liu Jian nodded, but now he can only find a way to break the deadlock.

Emperor Hongzhi thought of the Red Barbarian General and asked: "How about using the Red Barbarian General to defend the city with the Red Barbarian General?"

"I'm afraid that the Tatars will bypass Datong and head south from Zhenhe."

Ma Wensheng drew a line on the sand table.

The nine sides in the north are not connected into a barrier, and there are many wildernesses without walls that can go south.

Why do you have to conquer the city before you can go south?

This is a military strategy. If you go around the city and go directly south, you will easily be attacked from front and back, making dumplings.

It is different to capture the defending city. The enemy can use the defending city as a stronghold, and there are no enemies in the rear and you can retreat at any time.

But now, we act differently.

There were 70,000 Tatars and Jurchens. Even if the defenders surrounded them from behind, they could break through directly and ignore them at all.

"Let me think about it." Emperor Hongzhi stroked his beard without realizing that there were more people next to him.

Zhu Houzhao stared at the sand table, and the military flag representing the Ming Dynasty was not concerned: "Father, please let Lao Gao go. Lao Gao is afraid of death and will not let himself die in Datong. In this way, he will rack his brains to quell the Datong Rebellion."

Emperor Hongzhi was a little angry. When this man saw the sand table, he was like a cat seeing a fish, and he spoke nonsense here.

But Emperor Hongzhi remembered the nine-grid tactics of Yan Chengjin painting when he suppressed Hetao, and asked: "Where is Yan Chengjin, let him come to Fengtian Palace."

Soon, Yan Chengjin came to the hall and saw a huge sand table. Emperor Hongzhi and Jiuqing were all standing next to the sand table.

"Minist Yan Chengjin..."

Before he could finish his words, Emperor Hongzhi said directly: "The 70,000 Tatars captured Datong, and the defenders were only 30,000. Does Yan Aiqing have any ideas?"

30,000 to 70,000?

According to Yan Chengjin's character, he would directly beg His Majesty to allocate the defenders to 140,000.

It’s about the same thing as 140,000 to 70,000.

But Yan Chengjin also knew that the Beijing camp could not leave Beijing at will, and it would take at least one month for the army to head north.

Datong is probably over.

"There is a way, and after three days, you will see the results."

Qin Hong and Ma Wensheng's eyes flashed with shock.

I only realized that it would be difficult for 30,000 troops to fight 70,000 people. Even if I have the advantage of the city wall, it is a difference.

Li Dongyang whispered to Yan Chengjin: "Don't accept any unsure of things, so as not to delay the fighter's plane."

It has only been two days since the impeachment of Jiao Fang, and the censors are staring at Yan Chengjin.

If this failure is made, I am afraid that many people will impeach, especially Jiao Fang's disciple.

Emperor Hongzhi asked, "Do you know that Datong cavalry is not as good as Ningyuan border troops?"

I want to win more with less, but I am afraid I can't.

"I know that if Your Majesty allows you to go north from Song Jing, you may be able to fight this battle."

Song Jing had never been on the front line and stayed in the Censorate to edit the Ming Dynasty Congregation, so he might not be promoted.

Yan Chengjin asked him to go north, so he naturally wanted to make military achievements.

"War is not about writing a silly chapter. You can win by just talking. If you lose a battle, hundreds of thousands of people behind you will die under the iron hoof of Tatars." Qin Hong said.

It is not surprising that the Tatars slaughtered the people of border towns in order to control the population of the Ming Dynasty.

"I recommend Song Jing!" Yan Chengjin insisted.

Zhu Houzhao bowed and said seriously: "My son also recommends Song Jing."

Song Jing is his warrior, and Zhu Houzhao's most happy thing is to direct his warriors to fight.

Liu Jian couldn't take it seriously. This time the Tatars attacked the weak Datong, not the strong Sanbian Hetao, which was really hard to determine.

"Song Jing ordered the British Duke to stand by, and if the Tatars break through Datong and go south, they will go north to fight."

Emperor Hongzhi added another layer of protection.

…………

Outside the palace, Wang Gongchang.

Yan Chengjin and Song Jing stood in front of saltpeter together. Only Wang Gong Factory could prepare a large number of firearms.

"The firearm I want to make this time is very special, it needs to be buried underground."

"There are still such firearms in the world? They are like stone bombs."

Zeng Jian showed a slightly shocked expression, but did not doubt Yan Chengjin's words.

Song Jing, on the other hand, looked humbly asking for advice.

Only three days later, Yan Chengjin must hurry up: "The two types of firearms on this drawing are ordered by craftsmen to speed up the production."

Song Jing looked at the drawings and then looked at the production method.

The first firearm is easy to obtain, and can be made by slightly improved bowl-mouth guns.

Only this mine requires alum oil, which is a bit troublesome to refine this material.

Yan Chengjin said: "This thing is extremely dangerous, so be careful. It is limited to one day. It needs to be made and ordered by craftsmen to make it."

The methods are all written on the drawings, and it should not be difficult to use Song Jing’s current achievements in firearms.

This method is a record of the creation of objects by heaven.

With landmines, the Tatars' cavalry is not afraid of.

Not only can the Tatars be killed, but they can also panic when the war horses they are proud of.

In addition, there is another firearm, which is a big killer!

When laying out landmines, professional engineers are needed, which is why Song Jing must go north.

The development of mines was dangerous, and Yan Chengjin did not dare to stay in Wang Gong Factory, and told Song Jing: "After the development was made, I informed me of the official."

...

Forbidden City, Imperial Palace.

The Jinyiwei reported to Emperor Hongzhi: "Your Majesty, Lord Yan went to Wanggong Factory after leaving the palace."

This guy went to Wanggong Factory to prepare a firearm.

"What firearm can fight against the 70,000 army?" Emperor Hongzhi wondered.

After a while, Zeng Jian came to Fengtian Hall and begged Emperor Hongzhi: "Your Majesty, the Ministry of Works needs 30,000 taels of silver to purchase gunpowder materials such as saltpeter and sulfur."

"How do I remember that Wang Gong Factory still has thousands of saltpeter?" Han Wen knew very well about the various treasuries.

Zeng Jian said: "The saltpeter and sulfur from Wanggong Factory must be transported to Datong. In this way, the treasury of Wanggong Factory is empty, and it is difficult to mine saltpeter and sulfur, so it needs to be filled as soon as possible."

Yan Chengjin greeted him, and the gunpowder in the entire Northern Zhili was moved to Datong to let him fill it as soon as possible.

"What kind of firearm, you need so much gunpowder."

"I don't know that I heard Yan Chenggong Jin say that I need to be buried underground, called landmines, and its power can make the earth sad and the mountains and rivers lose their color."

Emperor Hongzhi couldn't help but become curious, and he didn't know how powerful he was compared to the Red Barbarian General.

When it's ugly at night.

The capital city is like thunder, shocking and shocking.

The people of Xicheng were so shocked that they escaped from their houses and panicked.

The people living in Wanggong Factory knew that the gunpowder exploded again and cursed.
