"General Hou, I have been taught."

Although Li Yan didn't care about what Hou Junji said, this did not prevent him from showing respect with his attitude.

After clasping his fists and saluting, Li Yan was ready to open his mouth and tell about cotton.

"General, in addition to encountering the Turks when I went out of the city today, I also found a very special kind of white stack, which should be of great use to our Fengzhou army."

Li Yan brought the topic on the right track, his main purpose of going out of the city today was still for cotton, and fighting the Turks was just incidental.

"White stacks?"

Hou Junji was slightly stunned, he knew this thing, this is an ornamental plant from the Silk Road, the flowering is extremely white, and many people in Chang'an like to plant this thing.

Hou Junji wondered, he couldn't figure out how an ornamental plant could be of great use to the army.

Li Yan knew very well why Hou Junji was puzzled, there was indeed a small amount of cotton planted in the Tang Dynasty now, but it was only used as an ornamental plant, and the Tang people did not realize that cotton had the ability to make ready-to-wear clothes to resist the cold.

After all, the cotton varieties that were introduced to the Tang Dynasty today produce extremely rare cotton, and because it comes from the Silk Road, its price is high, so naturally no one makes it into clothing.

"General Hou, the kind of white stacks I found outside the city today has an output of almost dozens of times that of ordinary white stacks! I once heard some merchants say that some nobles in the Western Regions would wrap white stacks in steps to make cotton clothes, which had an excellent effect of heat preservation and cold resistance. ”

Li Yan's half-truthful example is very straightforward to point out the cold-resistant use of cotton clothing.

He believed that with Hou Junji's military vision, he would naturally know how useful a plant that could be made into clothing to help the Tang army resist the cold.

"What do you say? Can white stacks be made into clothes to resist the cold? Tell me more! ”

Hou Junji's pupils shrank, he had been guarding the border for a long time, and he knew deeply the difficulty of the winter in the north.

Every winter, even he, the lord of the city, has to guard against the cold, and ordinary soldiers have no means to resist the cold, and they have to take turns to guard the city gates, which is simply a great torment.

"General, according to my observation, if this kind of white stack is planted, it can yield about 400 catties per mu, and about one or two catties of white stacks can make a cotton coat......"

Li Yan explained to Hou Junji in detail, and he noticed that with the release of a group of data, Hou Junji's eyes became brighter and brighter.

"Why don't I lead a battalion of men and horses out of the city, personally pick these wild white stacks, and collect the seeds."

Li Yan struck while the iron was hot, and tried to get Hou Junji's order as soon as possible to lead people out of the city to collect cotton.

After all, cotton is not something that can grow at this time and in this place, and if it drags on for a long time, Li Yan is afraid that those cotton plants will have problems.

"Okay, I'll leave this matter to you, make sure to retrieve the seeds of that white stack!"

Hou Junji's vision is still long-term enough, and he is very clear about the strategic role of this special white stack.

"Yes, General!"

Li Yan hurriedly accepted the order, and then hurriedly ran to the direction where the smoke rose before the meal had passed.

Twenty minutes later, Li Yan didn't even have time to clean the blood stains on his armor, so he filled all the men and horses of his battalion, and hurriedly left the city with carts, ropes, cloths and other transportation items.

……

At the same time, on the other side of Fengzhou, this place was the place where the 3,000 people led by Cheng Yanjin were temporarily stationed.

After Cheng Yanjin hurried back to the camp, he hurriedly picked up his pen and began to write letters.

"Your Majesty, after the minister rushed to Fengzhou after receiving the order, he worked diligently......"

"However, when today's minister saw the method of training soldiers and beheading the Turkic meritorious Li Yan, he suddenly found a ......"

"The minister did not find the loss back then, and finally saw the fruit......"

If such a scene is seen by outsiders, it will definitely drop its jaw!

Is this still the reckless man Cheng biting gold? Is this person who writes a fluent essay really the Cheng Biting Jin who can only scold and scold in the court?

I saw that Cheng Biting Jin's urgent letter had a clear structure and straightforward expression, and there was no half-minute Cheng Biting Jin's shadow.

At the beginning of this article, he highlighted his conscientious leadership and the hardships of the march.

The second text is extremely detailed, explaining his contact with Li Yan and the situation of the jade pendant.

In the end, Cheng Yanjin did not ask for any credit, but kept blaming himself for his failure to do so back then, and failed to find the person who held the jade pendant as soon as possible.

Of course, if there is any place to see that this urgent letter was written by Cheng Yanjin, it can only be the ugly handwriting and the full text of fake words (typos).

"Cheng Chumo! Get out of here! ”

Cheng Yanjin called out his own son as soon as he heard it, and now Cheng Chumo is serving as a personal guard in Cheng Yanjin's army.

"Daddy...... Checkmate! ”

Cheng Chu entered the general camp silently, he knew his own Lao Tzu's habits very well, and generally this form of direct scolding was eighty percent of what he had to order.

"You personally bring someone to send this letter back to Chang'an! Remember, there is absolutely no room for mistakes, be sure to ask Your Majesty to open it personally, if something goes wrong, you don't have to come back, you have no man's land to apologize! ”

Cheng Yanjin's expression was very serious, and the content of his letter was too much.

Although he was cautious in his words, he did not directly name the relationship between Yu Pei and Li Shimin, let alone the kind of speculation in his own heart.

But after all, it's a royal secret, and nothing can go wrong!

"Yes, General!"

Cheng Chumo cautiously accepted Cheng Biting Jin's secret letter, this was the first time he had seen Cheng Biting Jin's expression so solemn.

At this moment, Cheng Chumo only felt that the letterhead in his hand was extremely heavy, this was definitely a top secret in the army!

"Go ahead, take two guards and don't be too obtrusive."

Cheng Yanjin specially instructed, for fear that something would be unexpected.

"Yes."

Cheng Chu silently accepted the secret letter, agreed and left.

"Eh, I don't know how His Majesty will decide......"

Cheng Yanjin's eyes were a little ethereal, completely restraining his usual appearance.

To tell the truth, Cheng Yanjin was faintly worried in his heart, he knew very well that Li Yan was a military talent, and he was also a peerless general, so that such a talent would inevitably shine wantonly in the army.

But if his speculation comes true, then Li Yan may be recalled to Chang'an by Li Shimin, so as to intervene in the mess in the palace.

For a moment, Cheng Yanjin's mind even flashed the picture of last year's Xuanwu Gate, and he felt that if Li Yan really went to Chang'an, with his ability and force, maybe in a few years, the matter of Xuanwu Gate might have to be staged again.

"I hope Your Majesty will be as wise as ever."

Cheng Yanjin shook his head, scattered the messy thoughts, and then took out a water bladder, poured it in a big gulp, and the aroma of wine quietly appeared.

The next moment, Cheng Yanjin regained his reckless appearance.
