"Expedition!"

With Li Jing's order, the army marched out of the camp.

Now that the battle situation is urgent, there is no time to swear an oath, and even this night's delay is only a necessary preparation time for the army to assemble and the grain and grass to be pulled.

Therefore, Li Yan, who is now standing at the gate of the barracks and watching the soldiers go out, has become the best mascot.

The Marquis of Dingbei, who sealed the wolf Juxu, personally saw him off, which was enough to make up for the lack of morale caused by the lack of oaths.

"Cheer up! Dingbei Hou is looking at us! ”

"Hurry up! Don't delay, march fast! ”

"Is this the Marquis of Dingbei, the Marquis of Dingbei who sealed the wolf Juxu......"

The place where Li Yan stood was the only place to go out of the camp, and all the soldiers who went out on the expedition could take a close look at Li Yan and feel the heroic posture of the Dingbei Marquis.

"Boss ......"

Zhang Dazhu and others held different important positions, so they saw Li Yan in turn.

On the way to the march, although they could not leave the team without permission and say a few words to Li Yan, they could interact with each other with their eyes.

Whenever Li Yan saw them, he would give them an encouraging look, and then nod his head a few times, signaling them not to get too excited.

It's a pity that Zhang Dazhu and others completely misunderstood what Li Yan meant.

In their eyes, Li Yan's action is to say: "Use some force when killing the enemy, don't embarrass Lao Tzu!" ”

After receiving such information, several people were enthusiastic and determined to make a meritorious achievement.

Fortunately, Li Yan didn't know what Zhang Dazhu and others were thinking, otherwise he would have been angry, and then said angrily:

"I clearly mean to let you take care of your own lives!"

The above situation, Li Yan is impossible to know for the time being.

The marching procession was four men marching together, and the 30,000-strong army marched together, almost stretching for more than ten miles.

Li Yan stood here for a long time before he saw the many generals in the middle of the half-step.

Li Jing, Cheng Yanjin and others glanced at Li Yan one after another, and did not stop, and followed the army closely.

The urgency of the war is too great to allow any time to be wasted.

In this way, when the army all left the camp, and counting the time he had waited before, Li Yan had already stood here for nearly an hour.

The sky was already dark, and Li Yan embarked on the road back to Chang'an City.

When Li Yan came to the city gate, the Chang'an city gate had just reached the time to open.

The soldier who saw Li Yan on the city wall happened to be on duty today, and he saw Li Yan again at this time.

"I've seen Dingbei Hou."

When Li Yanlu crossed the city gate, the soldier hurriedly saluted and greeted him.

"Huh? Why are you so familiar? ”

Li Yan felt that this person was a little familiar, as if he had seen it somewhere.

"Back to Hou Ye, the humble name is Shen Chao, when the Hou Ye first came to Chang'an, it was the humble duty who took you to the imperial city."

Shen Chao replied respectfully, he is still replaying the scene before dawn today in his mind, and he still can't calm down.

"Oh, I remember."

Li Yan then remembered this soldier, and he remembered that when he first arrived in Chang'an City, he had a very pleasant chat with him.

After thinking of Shen Chao's identity, Li Yan was not ready to delay, and immediately prepared to enter the city to go to Tiangong Academy for today's arrangements.

"Master Hou, wait."

Li Yan had just left, but he was shouted by Shen Chao.

"What?"

Li Yan asked.

"Master Hou, actually...... If you want to get out of the city early, you can tell us directly, there is no need to climb the city wall in the middle of the night......"

Shen Chao struggled for a moment, and finally decided to tell Li Yan the truth.

After all, he himself is a city guard, and it is his duty to guard the city gates.

Li Yan climbed the city wall and went out of the city in the middle of the night, but in the final analysis, it was still an illegal operation.

In the future, if Li Yan does this again, and then is discovered by others, their city guards will be held responsible.

After saying the above words, Shen Chao added another sentence.

"As the Hou Ye, we only need to make a record to open the city gate for you, no trouble."

Shen Chao was afraid that Li Yan would misunderstand, so he hurriedly added such a sentence as a supplement.

"Got it."

Li Yan's rare old face turned red, he thought that no one saw it when he climbed the city wall, the ghost knows how Shen Chao found out when it was so dark and there was no order on the city wall!

Li Yan left the city wall in a slight hurry, he felt that he had never been so embarrassed as he was today......

After entering the city, Li Yan adjusted his emotions, entered the Tiangong Academy, and started today's arrangement.

Today, both handlooms and water-powered looms have been thoroughly perfected, and mass production can be achieved by employing an additional group of craftsmen.

Of course, the most important thing now is that the emergence of potatoes has greatly improved the livelihood of the people in Datang.

The fact that there is no longer a shortage of food allows Datang to begin economic development.

In other words, the first industrial revolution in Li Yan's plan has arrived!

Li Yan went directly to the ten craftsmen who had been learning to make drawings and began to arrange new plans.

"In a few days, I will set up a Tiangong Academy and recruit 100 craftsmen, and you will work in pairs to teach them cartography."

"In a few days, I will teach you basic mechanics and lay the foundation for the development of Tiangong Institute in the future."

Li Yan didn't take too many steps, and directly set the goal of the second step plan quite high.

In one fell swoop, he had to train dozens of craftsmen with a theoretical foundation, as well as hundreds of craftsmen who could recognize standard drawing.

The significance of Li Yan's move to industrial development is simply the same as that of Qin Shi Huang's unified writing for literature.

Li Yan didn't know at this time that it was precisely because of his second-phase plan today that he would have a good name in a few decades, called "the ancestor of Datang industry"

Of course, these are still later words, Li Yan's current stage goal is to cultivate talents, and promote the development of the first industrial revolution, and finally complete the achievement task, obtain enough achievement points, and unlock new modules......

In this way, the movement of Tiangong Institute in these days has become big again, and Li Yan's name has once again appeared in people's ears, and Datang Tiangong Institute has absorbed hundreds of craftsmen through the formation of "Tiangong Academy", and has entered a real period of rapid development, and gradually began to set off the prelude to the development of Datang industry.

……

On the evening of five days later, Chang'an had just entered the curfew, and Li Shimin was reading the recitals about the Tang Tiangong Academy in the Taiji Hall, and from time to time he showed his contemplation.

"Set up an academy, so that the craftsmen of the world respect you, quite the style of the ancient sons of a hundred schools......

Li Shimin doesn't have to wait until the future, he can see some clues now.

A few days ago, he had been to the Tiangong Academy, and he knew that there was a large amount of knowledge in the Tiangong Academy, which was extremely hungry for craftsmen.

Now that Li Yan has established the academy, he is obviously spreading knowledge.

Such behavior is no different from that of the sons of the pre-Qin hundred schools.

After this knowledge is completely spread, Li Yan will naturally gain the respect of craftsmen all over the world, and it is very likely that future generations will give him an identity.

Li Shimin nodded with satisfaction, and at the same time roughly calculated how many years it would take him to announce Li Yan's identity.

As an "erudite" emperor, Li Shimin knows very well that time will always dilute everything.

Ten or twenty years later, the people of the world will inevitably forget the scandal of his Li Shimin's murder of his brother and seizure of the throne, and the scandal of an illegitimate child will no longer make too many waves.

At that time, as long as Li Yan's achievements are not low, no one will be able to stop Li Yan's path of recognizing his ancestors and returning to his ancestors.

Li Shimin is still very confident in his own political methods.

Just when Li Shimin's mood was getting better, Wang De hurriedly ran in from outside the imperial study.

"Your Majesty! Border Emergency! Wei Guogong encountered an ambush on the way to support Shanzhou, Liangzhou was suspected of surrendering to the enemy, Xue Yantuo's soldiers and horses appeared at the boundary of Shanzhou, forming a siege with Tuguhun, 30,000 troops and in danger! ”

Wang De was in a hurry with a bloody emergency report, and explained the general content of the emergency report to Li Shimin while running.

"What?"

Li Shimin stood up violently, and anger suddenly rushed to his heart.

This may be the butterfly effect caused by Li Yan's crossing, or it may be a subtle deviation of history itself.

Li Youliang, the governor of Liangzhou and the king of Changle, who should have happened last year, has not moved.

And now a disturbance is a heavy blow to Datang!

Tuguhun and Xue Yantuo joined forces to invade the Tang Dynasty, and Li Youliang, the king of Changle, gave up the important passage of Liangzhou, so that the two sides completed the rendezvous near Shanzhou, and ambushed the reinforcements led by Li Jing together.

Such a means simply caught Datang off guard!

"Quickly let the hundred officials enter the palace to discuss matters!"

Li Shimin did not dare to delay at all, and now that he was faced with such a crisis, it might be another shame for him to say it carelessly.

Even this time, Li Shimin's pressure was much greater than when the Turks hit Weishui.

Although the original Turks fought all the way to Weishui.

But that was because the Xuanwumen Incident had just happened, and the Tang Dynasty was already a little empty, and the guards along the way had Li Jiancheng's men and horses, and they gave the Turks a chance to take advantage of the situation when they released water.

At that time, there were still more than 100,000 mobilized troops near Chang'an, and after a series of counteroffensives, the Tang Dynasty actually achieved a certain victory, and the losses of the Turks were not small.

The reason why the shameful treaty of the Weishui Alliance was decided at the beginning was just that Li Shimin took into account the actual situation of the Tang Dynasty and did not want to see a miserable victory.

In the final analysis, the matter of Weishui has always been under Li Shimin's control, and it is not a terrible thing.

But now, the alliance between Tuguhun and Xue Yantuo has really trapped nearly 40,000 troops in the Tang Dynasty.

Even Li Jing, the god of the Tang Dynasty, is mired in the quagmire!

Liangzhou happened to be delivered at this moment, directly cutting the Hexi Corridor into two.

When the Tang Dynasty faced Tuguhun and Xue Yantuo, it no longer had the geographical superiority of depth, but was divided by others, involving a large number of troops.

It can be said that now counting Li Jing's reinforcements and the troops of Shanzhou, Liangzhou, and the divided Shazhou and Ganzhou, Datang and more than 50,000 troops are in a predicament.

This number is undoubtedly quite scary.

Wang De has been by Li Shimin's side for a long time, and with a certain strategic vision, he naturally knows the seriousness of this matter, and immediately sent many eunuchs to inform him.

The hundred officials left their respective mansions in a short time and came to the palace.

"Ladies and gentlemen......"

A brainstorming began in the Imperial City, all of which were brainstorming and considering solutions to the crisis.

……

At the same time, in Cheng's mansion, Cheng Yanjin's two ladies almost fainted after getting the news.

"Sister, what should we do? If he makes a mistake while he's out there, I'll wait. ”

"Eh, wait, Your Majesty should send troops to rescue."

"However, the 30,000 army is besieged, how can the imperial court have extra troops to support."

"Sister, why don't we go and visit Dingbei Hou? He might have a way. ”

Just when the two ladies were anxiously communicating in their hearts, what Cheng Yanjin had said to them suddenly flashed in their minds.

"This Li Yan, one person can be alone in the city gate, such force, it should be the best in the world."

"If he charges into battle, I'm afraid that an army of 100,000 won't be able to stop him from taking the head of the enemy."

"Li Yan alone can reach tens of thousands of troops! He alone is enough to turn the tide of the battle. ”

The two of them suddenly thought of this.

At first, they only thought that this was Cheng Yanjin's drunken bragging, but now it seems to have become their last straw.

If Li Yan really has the ability that Cheng Yanjin said, maybe he is the only hope.

"Let's go! Let's go to Dingbei Hou Mansion! ”

Mrs. Sun, that is, Cheng Yanjin's eldest lady, made a decision immediately.

She is a strong woman, and although she has been immersed in aristocratic communication in recent years, she is still very decisive when she needs to make a decision.

In this way, Cheng Yanjin's two wives couldn't care about the curfew in Chang'an, and hurriedly went to the Dingbei Hou Mansion.

……

In the Dingbei Hou Mansion, Li Yan didn't know the situation in the outside world, and he was preparing to enter my world to go to the ender pearl.

Now he had collected nine ender pearls and combined them into the Eye of Ender.

Li Yan was only three short of the twelve Eyes of Ender, and at this pace, he would soon be able to collect them, and then set out to find the dungeon and start the journey of slaying dragons.

Just about to concentrate on entering "My World", the subordinates of the Hou Mansion suddenly came to report.

The two wives of Lu Guogong asked to see him.

At this moment, Li Yan was a little confused.

It's dark this day, why did Cheng Yanjin's two wives come to him?

Could it be that he wants to add some color to Cheng Biting Jin? Can't! Women in this era should not do such things (except for Princess Gaoyang)

Li Yan shook his head and threw the distracting thoughts out of his mind.

He saw the two ladies who bit gold in the process, and they were by no means the kind of people who were indecent.

Presumably, they must have something important to visit on this trip.

In this way, Li Yan no longer hesitated, and immediately saw them in the main hall.

As soon as they met, the two Mrs. Cheng became excited.

"Please also ask Dingbei Hou to save my family's ......"

"My fool said that if there is really someone in the world who can turn the tide of the war by himself, you are the only one over there."

Li Yan was stunned after hearing this, what to save? What kind of foolishness? Cheng bites gold? Cheng Biting Jin had an accident?

Li Yan was full of question marks.
