Yan Mountain, Heng Mountain, Taihang Mountain.

The three tall and majestic mountain ranges act as a natural barrier, keeping danger out of the grasslands to the north.

And Mobei City is a sharp knife interspersed into the grassland.

It can not only block the attack of foreign tribes, but also take the initiative to attack.

For hundreds of years, the Central Plains have relied on Mobei City, or in other words, under the Qin family's iron cavalry, the Rouran people have never crossed the defense line on the periphery of the three states.

So, it's all about forgetting.

In fact, from Heng Mountain, only a few hundred miles, you can reach the capital.

Standing on the tallest tower in the capital, you can almost see the curling fireworks closing the Yanmen.

It was an alarm pyrotechnic from the beacon tower.

As soon as the Yanmen Pass is broken, along the Jinzhong Plain, the Rouran people can ride all the way down to the capital.

There was a panic in the court.

The fast horse to Ganzhou came out in five waves within an hour.

Every wave was to make Qin Mohan hurry up and send troops at any cost.

And when Wei Zhaoti yì sent the Gyeonggi battalion north to help, An Guogong refused because of the safety of the capital.

Chu Yu was so angry that he scolded, but he didn't dare to forcibly send the Gyeonggi battalion to dispatch.

He is more afraid than anyone else that there will be no one to guard the capital!

The Beijing army totaled 300,000 people, in addition to the 150,000 in the Gyeonggi camp, there were 100,000 soldiers and horses in the five cities, and 50,000 Janissary Guards.

The capital is only a few hundred miles away from Yanmen Pass, but Ganzhou is more than 2,000 miles away, and the terrain is treacherous and difficult to travel, if you detour from Mobei, it is more than 3,000 miles.

When Qin Mohan was asked to send troops from Ganzhou to aid Yanmen Pass, the decision to move the Beijing army was issued.

Wei Zhao directly threw the jade plate in his hand.

Fortunately, Chu Yu then ordered that all the money of the household department, including the monthly salary to be given to the Gyeonggi battalion (the border army is paid twice a year, and the Beijing army is paid monthly) and the military salary behind, all of them were transported to Ganzhou by horse.

Wei Zhaocai picked up the jade plate again and stared at Ning Shangshu to transport the money.

The beacon fire at Yanmen Pass burned for three days, and with the extinguishing of the beacon fire, it was an 800-mile urgent letter from the Jinju Zhizhou.

There are 3,000 garrisons in Yanmen Pass, which is under the jurisdiction of the Gyeonggi battalion.

After lingering outside the gate for two days, the intruding Rouran people began to attack the gate.

The general of the pass took the lead in retreating, and most of the 3,000 garrisons ran away, and in less than an hour, the gate was breached.

The Rouran people drove straight in, and in less than half a day, they killed the Jinju Governor's capital.

(When Zhizhou described this, he used a thousand-word text to describe the critical situation, the panic of the people, the destruction of the city, and the uselessness and inaction of those officers and soldiers)

The city walls of the state capital are not high, and seeing that the Rouran people are about to attack the city, it is like a surprise soldier from the sky.

A thousand cavalry came in from the Yanmen Pass.

Surrounded and annihilated those Rouran.

At this time, Zhizhou knew that there were not even a thousand Rouran people who invaded the pass.

The cavalry that came to the aid came from Mobei City.

Mobei City was surrounded by 200,000 Rouran people, the food in the city had been eaten, and the soldiers were hungry by gnawing on the roots of the trees, but when they saw the beacon fire at Yanmen Pass, General Zhenbei still took a seriously injured body and personally charged, covering the thousand cavalry to come to the rescue.

(Zhizhou once again used a thousand-character prose to describe the tragic situation of Mobei City and the bravery of the 1,000 cavalry)

After the fold, Zhizhou said that he had asked the 1,000 cavalry to garrison Yanmen Pass, replacing the soldiers of the Gyeonggi battalion in front of him who ran away from the enemy, and asked the imperial court to agree that Jinzhou would use the autumn tax collected this time to buy grain and transport it directly to Mobei City.

(Speaking of which, he used 100 words to describe the spontaneous beginning of the people of Jinju to donate food and money to aid Mobei City)

Jinju Zhiju is a world-famous scholar and talent, born in a family, brilliant writing, that song is written with emotion and passion.

Its last few words: 3,000 defenders were defeated by hundreds of enemies, the city of Mobei was broken, and 200,000 Rouran people went south, but in one day, the capital was in danger.

In the end, it made the people in the court blush.

Chu Yu smashed the fold directly into An Guogong's face, and ordered repeatedly.

First, the 1,000 people who came to the aid from Mobei City took over the defense of Yanmen Pass, and then approved Jinzhou to directly transport grain to Mobei City.

Approved Wei Zhao's mention again, Yanzhou Jizhou autumn tax did not enter the household department, and was sent directly to Mobei City.

After the repeated edicts came down, it didn't take long for the Jinju Zhiju to spread all over the capital, and then another incident happened in the capital.

That is, the lord of Rongning sold all the gifts and his jewelry and clothes from the wealthy family in Jiangnan, and saved 60,000 taels of silver in exchange for food, so that the guards in the palace could send them to Mobei City.

And said that those guards didn't have to come back, and went directly to Mobei City to participate in the battle.

It is said that when the county lord bought grain, he said that the 70,000 iron-blooded sons of Mobei were not killed in battle but starved to death, and she was powerless to do anything as a woman, so she could only do her best to ask Mobei to starve to death.

As soon as this incident came out, the merchants in the capital also donated money to help, and more than 100 merchants pooled together 200,000 taels of silver, bought a large amount of grain, and sent it to Mobei together with the grain of the county lord.

At the same time, the Yanmen Pass guard will be the nephew of the Duchess of An Guo, the cousin of the concubine in the palace, who was originally a gentleman, and he relied on the relationship of An Guogong to become such a guard, but as soon as the enemy attacked, he abandoned the pass and fled, and it was also publicized everywhere.

An Guogong's various statements, why he can't send troops to aid is to protect the capital, suddenly became a big joke.

And Hubu Shangshu detained the border pass military rations and did not distribute them, making Mobei City a miserable situation (as evidenced by Zhizhou's recital), which is really evil!

All kinds of rumors went viral, and the Duke of An Guo and the head of the household were so angry that they smashed the fragments of a study at home.

At the end of September, the latest battle report came.

Qin Mohan personally led the army from Ganzhou to aid Mobei, and was ambushed by Rouran's 200,000 troops at the foot of Yin Mountain, followed by Rouran's army, and was forced into the Gobi.

There was no trace of it.

The Gobi is a desert connected to the desert, and the vast and endless scenery is the general scenery, even the Rouran people who have lived there for generations will get lost.

And because of the lack of food and grass, the 50,000 cavalry that Qin Mohan brought only brought dry food for three days.

Once you get lost in the Gobi, the consequences are unimaginable.

As soon as this news came, Chu Yu couldn't sit still anymore.

If Qin Mohan dies, if Mobei City is defeated again, the capital will be defended, and he may not be able to sit firmly on the throne.

Even if he is still the emperor, he will inevitably be subject to those important ministers of the family, especially An Guogong.

And at this time, Gonggong Chang sighed softly beside him again, how could the general gallop to help Mobei be known by the Rouran people?

He also gathered an army of 200,000 at once.

At this time, there was an excerpt of Yanzhou's good news, saying that most of the Rouran army besieging Mobei City had retreated, and the people of Mobei City had opened a hole and asked them to send money, food, clothing, etc. in.

Chu Yu immediately thought that half of the ambush under Yin Mountain was from Mobei City.

And how did the Rouran people in Mobei City know that Qin Mohan would go down from Yin Mountain!

That night, the old lady of the Zuo family was announced into the palace, and when she came out in the middle of the night, she was carried out.

And Concubine Fu was placed under house arrest in her palace.
