After hearing that Yuwen Yuanliang had been tied up and escorted to Chang'an City.

Zhao Youlin immediately began his own deployment.

His strategy was very simple, that is, to take all the remaining soldiers directly north to join Xue Yantuo.

But in wartime, he is a commander-in-chief, and he can command thousands of troops.

But when it was time to withdraw, even if he was the commander, few people were willing to go with him.

More than 20,000 soldiers of the Three Clans Alliance Army only asked to go home regardless of Zhao Youlin's orders.

No matter how much the Overseer camp tried to kill the soldiers who didn't want to go, the rest of the people didn't waver.

Serving in the army, no matter what country or place you are.

The reason why they picked up long knives and fought the enemy regardless of life and death was for their families and hometowns.

If they are allowed to leave their hometowns and families, what is the point of being soldiers?

In the end, Zhao Youlin can be regarded as seeing through the mentality of these people.

He also knew that if he forced these people, it would cause even more trouble.

Rather than this, it is better to accept it when it is good.

Therefore, he simply led the more than 20,000 people who were willing to go with him to the depths of the desert.

The remaining 20,000 people stayed where they were and surrendered to the Tang Dynasty.

This war, which was provoked by Zhao Youlin and expanded by Li Chengqian, has finally come to an end.

In this battle, the Tang Dynasty paid a total of more than 30,000 casualties and soldiers, and included the vast land north of Yanshan into the territory of the Tang Dynasty.

The northeastern border of the Tang Dynasty will also be fully bordered by Murowei, Ya and Goguryeo.

……

When the army retreated south, Li Chengqian did not choose to return to Chang'an with the team.

He only handed over two letters to Li Tao and asked him to help bring them to Li Shimin and Lu Wanjie, who had been waiting for him in the palace for more than half a year.

The letter to Li Shimin was a question mark for Li Shimin.

Then he said that he still had a lot of things to do, so he would not return to Chang'an City for the time being, and when everything was arranged, he would go home for a reunion.

And the letter to Lu Wanjie is full of longing.

He even wrote in his letters that the last person he thought of was her during his experience.

After Lu Wanjie saw it, she felt both moved and sad.

She held the letter and looked at the north stupidly, muttering, "When will you come back, I really miss you......"

As everyone knows, she just let out this exclamation.

Li Chengqian, who was thousands of miles away, heard the system prompt sound.

Among them, there is Lu Wanjie's admiration value, and there is also Lu Wanjie's resentment value.

Li Chengqian couldn't help but shake his head and smile bitterly: "I know you miss me very much, but I really have a lot of things to do yet." ”

He looked up at the south: "But don't worry, after I go back, I will definitely go to see you as soon as possible......"

……

After solving the Northeast three times, Li Chengqian can finally be a bear child in the field house with peace of mind.

Although it was winter, it did not delay Li Chengqian to lead the people and the 20,000 prisoners of war of the three ethnic coalition forces to reclaim the land.

With the addition of these prisoners of war, the work of clearing the farmland progressed quickly.

At the same time, he had a large number of wind-powered mills and canals built on the grasslands to irrigate farmland.

Wind mills can not only provide kinetic energy for irrigating farmland.

It can also be used in a series of light industries such as papermaking, weaving, and forging.

After a busy winter and an unknown amount of money, a quaint light industrial zone has been built.

On the day when the light industrial zone officially began operation, Li Shimin came uninvited.

See yourself Lao Tzu.

Li Chengqian happily jumped straight on the spot.

Regardless of etiquette, he rushed directly to Li Shimin and gave Li Shimin a big hug.

Li Shimin just wanted to open his mouth and scold.

I heard Li Chengqian say something slowly; "Father, my son misses you so much......"

Just this sentence almost brought tears down to Li Shimin's words.

The reprimand, in the end, also turned into appeasement.

He patted Li Chengqian's back and pretended to be dissatisfied: "Miss me, why don't you go back to Chang'an to see me?" ”

"Looking at you like this, I'm afraid I have forgotten your father a long time ago and just cared about doing your own thing."

"How is that possible?"

Li Chengqian was also a little dissatisfied, pouting and saying: "Erchen really misses his father and mother all the time. ”

"It's just that the progress of the project here is slow, and I can't get out of the way and go back."

"Okay, okay, don't talk about this useless reason."

Li Shimin waved his hand indiscriminately, and raised his hand to press on the top of his head.

After half a year, he seems to have grown a lot taller.

The last time I saw him, he was only up to his chest.

Now it's up to the position of my chin.

Time flies.

In the blink of an eye, the child has really grown up.

Youth is gone, let alone a childhood that passes faster than youth?

Li Shimin sighed slightly: "Take me to see what you have done all these days." ”

"Okay."

Li Chengqian also wanted to show off in front of him the results of his hard work for so long.

He took Li Shimin straight into the first wind mill.

{Received Surprise +99......}

He raised his hand to the strange thing in front of him and asked with a surprised face, "What is this?" ”

I saw a wooden machine in the center of the huge mill, which was moving in an orderly manner.

And with the movement of the machine, a complete silk cloth is slowly pushed out.

When the size was almost the same, the workers who were standing by immediately stepped forward, cut the silk cloth with scissors, and then trapped it into a roll of cloth and placed it aside.

Li Chengqian smiled and introduced: "This is called a wind-powered loom, and the specific principle is similar to that of a wind propeller. ”

"Wind is used as kinetic energy to drive machinery for cloth weaving."

"The quality of the silk cloth spun by this thing is better than that of human spinning, and the output value is much more than that of ordinary cloth spinning."

Listen to him.

Li Shimin stepped forward and carefully checked the quality of the silk cloth.

Seeing the end, he couldn't help but smile and said: "If this kind of industry can be opened all over the country, no one in our Datang will wear linen clothes in the future......

"That's natural."

Li Chengqian smiled proudly and continued to pull Li Shimin down.

In the light industrial zone, there are countless wind-powered papermaking, wind-powered water extraction, wind-powered forging of steel, wind-powered grinding of grains, etc.

Li Chengqian has used the wind almost to the limit.

And this also made Li Shimin so shocked that he couldn't close his mouth.

He looked at Li Chengqian with surprise on his face and asked, "How did you come up with these strange things?" ”

"Of course the old fairy in the dream told me."

Li Chengqian had a smug smile on his face: "Moreover, he also told me a very interesting thing, but I haven't studied it yet." ”

"When I build it in the future, my father will be able to go to all parts of our Tang Dynasty at a speed of thousands of miles a day."

Hearing this, Li Shimin shook his head and smiled: "If I really want to travel thousands of miles in a day, why use your invention?" ”

"I only need to ride a good horse, and I can travel a thousand miles in a day."

"Hey, hey."

Li Chengqian glanced at Li Shimin and said, "I don't ride this thing, but sit on it." ”

"Sitting?"

"What's that?"

Li Shimin was a little curious.

"The Buddha said, don't say it."

Li Chengqian sold it.

"You'll know when the time comes......"
