Qin Qiong and Wei Chigong came out of the queue almost at the same time and shouted to the emperor to invite him to be the vanguard.

Compared with the steadiness of the elderly veteran general Wei Wensheng, these two generals in their early thirties are in the prime of life, and they will not think about the danger of the soldiers, nor will they think about the logistics and grass of the 400,000-strong army to attack in all directions.

They think it's simple.

The emperor said that if he wanted to fight, then he would beat his mother.

It is absolutely impermissible for the Turks to be so vicious that they will slaughter and kill people, not to mention destroying cities and seizing land.

The king humiliates the ministers to death!

Jieli Khan dared to bully the head of the Great Qin Emperor, how could they, the Great Qin generals, sit idly by.

"Okay, the two generals are loyal and commendable, I will award General Qin as the general of rebellion, General Wei Chi as the general of Pingyu, and the two generals will each lead an army as my vanguard!"

Once the emperor's will has been issued, it has never changed.

A proclaimer galloped out of Taiyuan with his will and went to the Quartet to announce his will.

Fortunately, it is said that 400,000 troops attacked, but not all from Taiyuan, but from Taiyuan and Boling, Shanggu, Beijing four places attacked, and Taiyuan and Fanyang, these two places, were originally important towns in the north, and the Sui Rebellion did not suffer too much war, after the establishment of Qin, also took these two places as the center of Hebei and Hedong, so they also accumulated a lot of money, grain, ordnance and other materials, and these two were logistics supply bases, but they were not without food.

However, to supply 400,000 troops, the number of people recruited must be as many as multiples, basically this time, Hebei, Hedong, Henan and other places, most of the young and strong must be recruited, roughly three to draw one ding of the limit of mobilization.

Such a scale of war is definitely not sustainable, and Wei Wensheng and other experienced veterans suggested to the emperor that it would be three months at most.

If the victory cannot be won within three months, or the scale of the war is reduced, the Qin army will have no food, and the entire Hebei Hedong and even the Central Plains will collapse.

This is not an exaggeration, but a fact.

"Three months, that's enough!"

Luo Cheng couldn't last three months, how could Jieli last three months, how could Liu Wuzhou last three months, and Chai Shao could last three months.

This war is not only very dangerous for Luo Cheng, but also for the enemy army, if they can't defeat Luo Cheng and attack the Great Wall, then they will have no food to continue in this remote Saibei, and they will have to collapse.

It depends on who can win first, even if it is a stalemate, both sides will be the same.

Daibei.

Cloudsdale.

At night, a few flying pigeons entered the city.

On the pigeon tower in the center of the city, Li Keshi, the prince of Danyang County, the Taishou of Yunzhong County, immediately grabbed a handful of pigeon food and threw it in, and only after the pigeons were full did he grab the pigeon and take off the letter box on his feet.

"One hundred flying pigeons have been released one after another, there are Shuntian pigeon station, there are Taiyuan pigeon station, and Hengshan pigeon station, and now there are finally pigeons from our Yunnei pigeon station flying back."

Flying pigeon biography is a very magical technology, which requires clever pigeon trainers to train birds to improve pigeon breeds, these flying pigeons are specialized pigeons, which were originally used by nobles to play and show off, and later Luo Cheng arranged for the secret guard to study and improve, and finally formed a carrier pigeon that can transmit secret letters.

Taking advantage of the pigeon's natural tendency to return to the nest, the method of transmitting information is actually very simple.

For example, Yunnei and Fan Yang are 800 miles apart, and the carrier pigeons can travel directly at this distance without the need for intermediate force transmission. Yunnei sent a pigeon letter to Fan Yang, and it was necessary to transport the flying pigeons from Fanyang Pigeon Station to Yunnei City for temporary foster care in advance, and when the message was to be transmitted, the letter was loaded on the pigeon's legs, fed, and then released.

The pigeon will naturally fly back to his nest in Fanyang, this is the nature of the pigeon's nest, no matter how far away, it will usually fly back.

Of course, in order to ensure the security of information, the pigeon letter uses encrypted ciphertext, and at the same time, as long as the important information is used, and a message is released many times with several pigeons, so as not to be hunted by natural enemies such as eagles, or intercepted.

It is very troublesome to take a carrier pigeon from Fanyang to Datong, which is 800 miles, but put it back, and the pigeon can arrive in only one day, but it is extremely fast.

"Danyang Gong, how is it?"

Liu Hongji heard that a flying pigeon had returned, and immediately came over.

Li Keshi is Li Jing's younger brother, this is a master of playing birds, Datong's pigeon station has more pigeons than other stations.

"I've handed over the pigeon letter to the staff interpreter."

The staff officer was in possession of a translation of the pigeon letter, which was designed for the transmission of the pigeon letter and was changed at regular intervals. He handed the translated pigeon letter to Liu Hongji.

"Is it another letter for us to break out and evacuate?"

After Liu Hongji read it, he just shook his head.

"General, Jieli has crossed the Hu Pass, and it will be there soon, if we want to withdraw, this is our best chance." Li Keshi reminded Liu Hongji. Liu Hong was basically a general of Dingxiang and was sent to Mayi to take over as the envoy of the Dingwu army, but the Dingwu army rebelled, and he only returned to Yunnei with a part of the soldiers and horses.

He is a guest general, but Li Keshi is the Taishou of Yunzhong County, but Li Keshi did not compete with Liu Hongji for power, the enemy is currently the enemy, and he is responsible for defending the city against the enemy.

Even now whether it is a war or a withdrawal, he asked Liu Hongji first.

Liu Hongji said with a smile, "Your Majesty issued an order, let me wait to break through the siege and go north, and let us give up Yunzhong County." However, there was news from Shuntianfu that the emperor had issued an edict to attack the four armies, and the 200,000 soldiers in the army were divided into four routes to the north. ”

"What if Jieli comes? He thought that if he broke Dingxiang and Dali City, he would be able to break my Cloud City? ”

Cloudsdale was extremely strong in the last battle against the Turks. And since then, Cloud City has been in the hands of the Qin army for several years, and it has naturally been further strengthened.

"I only have 5,000 soldiers in Cloud City, but there are still 2,000 in Heng'an Town, and there are 1,000 in Cowhide Pass. The cities are connected, each other is horns, the morale of the soldiers is high, the fighting spirit is high, why can't they stick to the battle? ”

"Besides, there are more than 50,000 people in Cloud City, and there are more than 10,000 Qingzhuang, and these people can completely help defend and help the war. We can hold out until Your Majesty's reinforcements arrive! ”

Taishou Li Keshi listened to it and did not refute it.

Just smiled and said, if General Liu has this determination and ambition, then I, a civilian official, will naturally fully support it. I am too shou in the clouds, and it is my responsibility to defend the land, and I should stick to the city.

So, although this was the eighth retreat edict they had received, in the end Liu Hongji and Li Keshi still decided to continue to hold on.

Almost at the same time.

Hundreds of miles further north, in the Yinshan White Road, Luo Siye also received an edict from the emperor.

The emperor ordered him not to fight hard with the Turks, saying that since Dingxiang and Dali City had not broken the army, then he should simply detour to Mobei and return to Beijing through Xijing.

"Heiye doesn't dare to obey the edict, the blood of the 20,000 Dingxiang soldiers has not dried, and the blood of more than 20,000 Dingxiang people has not dried, my heir does not dare to leave like this, and the heir refuses to resist the edict!"

Luo Siye gritted his teeth and burned the edict.
