"Eat some steamed buns first, and then go into the city in a while, and my uncle will invite you to a big meal."

The eldest grandson Wuji took out the steamed buns from the package and handed them to Li Chengqian.

Li Chengqian looked back at the eldest grandson Wuji, his eyes full of grievances.

If you ask Li Chengqian what he regrets most in his life.

That is to believe in Li Shimin's evil.

When Li Chengqian came out, he said that he would catch pheasants for him to eat.

As a result, not to mention pheasants along the way, being able to eat a house finch is to improve the diet.

After leaving Chang'an City, Li Shimin specially looked for a ravine where no one was around.

When I entered Hedong Road, which is now in Shanxi Province, it was already half a month later.

In the past half a month, Li Chengqian really regretted not being at the beginning.

Why are you here?

Isn't it fragrant to stay in the palace of Chang'an City?

Looking at Li Chengqian's sad face, the eldest grandson Wuji and Cheng Yanjin looked at each other, shook their heads and smiled.

This time, Li Shimin specially instructed the eldest grandson Wuji and Cheng Yanjin not to bring too much money.

This is clearly what Li Shimin wants Li Chengqian to suffer.

At this time, Li Shimin opened the curtain and got into the carriage from the outside.

After rubbing his hands, Li Shimin said: "The winter in Hedong Road is much colder than in previous years. ”

When the words fell, he didn't forget to sigh: "The people here are going to suffer......

"If you are sinned this year, you may not be sinned next year."

Li Chengqian looked out the window.

Two days ago, there was a heavy snowfall, and now it is a blank white as far as the eye can see.

Li Chengqian took a bite of the cold steamed bun and said quietly: "Ruixue is a good year, next year's wheat harvest will definitely be good." ”

"Qian'er is right."

The eldest grandson Wuji also echoed on the side.

"After the Han Dynasty passed, the weather gradually warmed up, and the snow water melted into the soil, which was very beneficial to spring plowing and sowing and the growth and development of crops."

"And that's not all......"

Li Chengqian shook his head and said: "I have read in the book that if the weather is cold in winter, the snow is often not easy to melt. ”

"The snow that covers the soil is relatively soft, and there is a lot of immobile air in it, and the air does not transfer heat."

"It's like putting a quilt on the crops, and no matter how cold it is outside, the temperature below won't drop very low."

"The main thing is that the pests lay their eggs in the mud or in the riverbed."

"If the winter is cold and there is a lot of snow in the winter, when the snow covers the ground and the riverbed, many pests will freeze to death."

"So the colder the weather in winter, the less likely it is to cause locust plagues and insect plagues."

Speaking of this, Li Chengqian suddenly remembered something.

"Dad, this year's Chang'an City is a rare warm season."

"If you follow this theory, you must be prepared to prevent insects."

"That's true."

Li Shimin nodded thoughtfully.

Then he turned his head to look at the eldest grandson Wuji: "Wuji, when you return to Chang'an, remember to remind me." ”

The eldest grandson Wuji nodded yes.

The carriage traveled all the way north, arrived in Jinyang in mid-October, and arrived outside Yanmen Pass in the second half of October.

Since ancient times, Yanmen Pass has been the gateway to the Central Plains, and it is also a place where heroes come out in large numbers.

Li Mu during the Warring States Period, Li Guang during the Western Han Dynasty, and Xue Rengui, who is now not a few years older than Li Chengqian.

And the reason why these people became famous is nothing more than one, fighting against the northern desert nomads.

The nomads of the Northern Desert have not given up their snooping on the Central Plains since ancient times.

First there were the Xiongnu, then there was Tiele, today there is a Turk, and then later, there are Liao, Jin, Mongolia.

It seems that the northern part of China really settled down only in the Qing Dynasty.

In the end of the war, almost all the people who have not moved from the border have stopped taking the beheading seriously.

No matter what the Hu people in the Northern Desert want, they can live how they should live.

Especially in the Tang Dynasty of the government military system, the border people were the people when they were farmers, and they were pawns in wartime, from their ancestors to their grandchildren, except for the babbling dolls.

The rest of the people almost all had the smell of blood from the smoke of war.

……

On this day, it snowed heavily under the Yanmen Gate.

The border liquor shops are lively.

It's cold, and almost all the drinkers in the liquor store are foot merchants.

Some people ordered spirits to warm their stomachs, and some people ordered tea and drank slowly.

At this time, the three men took a boy into the wine shop and found a remote corner to sit down.

The three men ordered a few side dishes, and two pots of spirits, which were extremely difficult to drink but very stomach-warming, and drank them slowly.

As for the boy, he was holding a bowl of hot goat's milk, sitting upright and watching the snow in a daze.

The shopkeeper in the wine shop was already a well-informed person, and he couldn't help but take a few more glances when he saw them.

Although these men were in rags, they did not look like they were from poor people, but why did they come to this place in this bitter cold time to suffer?

Aren't you afraid of freezing to death on the streets?

The dignified son Li Chengqian, who has been tossed along the way, has become a little beggar.

And the dignified Tang Dynasty Taizong Li Shimin has become an old beggar, where is there still that high-spirited appearance.

Among the few of them, Cheng Yanjin, who has rough skin and thick flesh, has not changed, and he can still drink and sing songs.

Li Chengqian took a sip of goat's milk to warm up his body: "Before, my father said that the people in the north were not happy, and this is true. ”

"But in my opinion, the people of this northern desert should be even more uncomfortable."

Li Shimin raised his eyebrows and looked at Li Chengqian.

Li Chengqian smiled: "Dad, you think, our Tang Dynasty has Taizong's Wentao Wuluo, and the northern residents still have to suffer from the cold." ”

"Then the Northern Desert caught up with the old man Jieli, under the governance of this guy, it is strange that the people of the Northern Desert are not killed and injured."

Hearing Li Chengqian say that he was martial and martial, and called Jieli an old horseman, Li Shimin couldn't help but smile on his back.

Li Shimin pointed at Li Chengqian and scolded with a smile: "You kid is always open-mouthed. ”

"But what Qian'er said is also quite reasonable, last year there was heavy snow in the northern desert, and countless cattle and sheep froze to death, and the people complained."

The eldest grandson Wuji said on the side: "This year, the Northern Desert has caught up with such a cold again, and it is strange that the people can get well." ”

Li Shimin nodded thoughtfully, and then looked at the eldest grandson Wuji.

"Then do you think we should ......?"

After Li Shimin wrote the word 'Liang' on the table with a drink, he continued: "Take this place back? ”

Is there still that beam in this world?

It is nothing more than Liang Shidu, who has always occupied Shuofang in Xiazhou.

Liang Shidu can be a real dog leg of the Northern Desert Turks, and since the establishment of the Liang State by the emperor in the thirteenth year of the Great Cause, he has been eye-to-eye with the Turks.

And this goods not only invaded Lingzhou three times and twice, but also provoked the Turks to oppose the Tang Dynasty.

The Weishui Alliance, which was regarded by Li Shimin as the shame of his life, was created by this product.

Li Shimin's hatred for this product is no less than how much in the Northern Desert.

Hearing Li Shimin's words, the eldest grandson Wuji pondered: "If we send troops, the north will inevitably come to the rescue, and I am afraid that it will not be able to end at that time......"

"This ......"

For a time, Li Shimin was also in a dilemma.

If you attack Liang, Jieli will inevitably come to the rescue, if Tang and Beidesert start a fight, it will be difficult to recuperate.

Who knows, at this time, Li Chengqian, who drank all the goat's milk, suddenly spoke: "Isn't it that you don't want Beimo to send troops, what's so difficult about this?" ”

Seeing Li Chengqian's triumphant appearance, Li Shimin frowned and asked, "Do you have a way?" ”

Li Chengqian pushed the empty bowl in front of him: "Another bowl of goat's milk, I will definitely think of a foolproof plan for you......"
