After this day, a total of six caravans finally completed the delivery of cattle and sheep, and each caravan successfully took away a glass cup from Li Yan's hands.

Stimulated by these six caravans, the other caravans couldn't sit still at all, and they had to compete quickly for the last four chances.

Because of this, three more caravans gathered cattle and sheep that night, and kept guard at the city gate until dawn to enter the city for delivery as soon as possible.

Finally, during the day on the third day, all ten of Li Yan's glass cups were sold.

This time, he obtained more than 5,000 sheep and more than 200 cattle.

In order to deal with these cattle and sheep, Li Yan mobilized several villages around Fengzhou to help, and the sheep were either temporarily raised in captivity or directly made into cured mutton for storage.

Of course, the act of slaughtering cattle and eating meat is against the Tang law in this era, so Li Yan had to divide this batch of cattle into two batches, one group was temporarily lent to farmers outside the city to help them plough in the spring next year, and the other group was "raised" in the open cowshed, waiting for the arrival of heavy snow.

At this point, the winter preparations of the entire Fengzhou have been prepared, the Fengzhou army is now abundant in materials and there is no shortage of meat, and Li Yan can completely maintain normal training in winter.

Life in Fengzhou gradually returned to normal, and some Hu merchants chose to go to Chang'an, Taiyuan and other places before the winter, while others chose to temporarily stay in Fengzhou and wait for the spring of the next year to do business.

All in all, the winter of this era is very stable, and everyone and forces will be dormant, and it will not recover again until spring.

……

Ten days later, on the city wall of Fengzhou, Li Yan and Cheng Yanjin were gazing at the north here.

"It's getting cold."

Li Yan sighed, although it is normal to turn cold in winter, Li Yan knows very well that this year's winter will not be calm, and an unprecedented heavy snow will sweep across the north.

When there is a snowstorm in the grasslands, a city like Toyosu in the north will also be covered in severe cold in the north.

"Nephew, you said there will really be heavy snow this winter?"

Cheng Yanjin's unconsciously titled Li Yan has changed, in addition to Li Yan's frequent accidental verbal injury to Cheng Yanjin these days, his performance in all aspects has been completely recognized by Cheng Yanjin.

"General Cheng, just look at it, there will be a snow disaster this year!"

Li Yan is very sure, and all the history books of later generations clearly write that from the first year of Zhenguan to the third year of Zhenguan, there were three consecutive snow disasters in the north!

During these three years, the vitality of the Turks was greatly damaged, but the many fortress cities in the north of the Tang Realm were also miserable.

As soon as Li Yan's words fell, Cheng Yanjin felt a trace of coolness on his face, he subconsciously raised his head, and suddenly found that there were snowflakes falling in the sky.

"This ......"

Cheng Yanjin's eyes widened in shock.

Snow is normal in winter, and it's even more normal in winter in the north!

But it's only the middle of November!

November is still the time of year before winter officially begins, and the snow has already begun to fall, so you can imagine how terrible this year's winter will be.

"General Cheng, go back to the camp, organize normal military training, and be ready to deal with the Turks at any time, I will ask Zhang Dazhu to send five hundred sets of cotton clothes to Nanying."

Li Yan looked at the snowflakes falling in the sky, and his heart was very calm.

After all, it was expected, and even if you were surprised, you can't do anything but face it calmly.

"It's really snowing, Your Majesty, Your Majesty, what kind of eldest son did you give birth to......"

Cheng Yanjin muttered to himself, looking at Li Yan's departing back full of horror.

……

A few days later, in Chang'an City, the eunuch Yuan Yu traveled and carefully carried the glass amphora fine-grained cup that Li Yan asked him to bring back to Chang'an to present to the emperor.

The first thing he did when he entered the imperial city was to meet the old eunuch Wang De, who took him to meet Li Shimin again.

"Old slave, meet Your Majesty."

Yuan Yu dragged a wooden box with both hands and respectfully saluted Li Shimin.

"Excuse me, let's talk about it, how do you feel about going to Toyosu this time? Also, what are you holding in your hand? ”

Li Shimin was still paying attention to Li Yan's own son for the first time, but he ignored the wooden box held by Yuan Yu.

"Back to Your Majesty, this is a treasure that Li Yan, the defender of Fengzhou, dedicated to His Majesty."

Yuan Yu handed over the wooden box to Wang De.

Out of caution in his nature, Li Shimin's eyes motioned for Wang De to open the box.

"It's ...... Hiss ......"

When the box was opened, Rao is Li Shimin had seen countless treasures, and he couldn't help but gasp.

As an emperor, he naturally knew glass products, and merchants from the Western Regions had already brought glass to the Tang Dynasty.

But Li Shimin has never seen such a crystal clear glass product, the purity of this thing is like crystal, but it is full of strange beauty that is different from crystal.

This is the mutated item glass amphora fine-grained cup that Li Yan got from "Minecraft", a glass product that can be ranked at the level of handicrafts even in modern times.

"This kid has a heart."

Li Shimin slowly picked up the glass ear fine-grained cup and stroked it carefully.

Wang De on the side looked at Li Shimin's appearance, very entangled, he felt that he shouldn't be waiting here.

You must know that if this is a gift from another official, Li Shimin will be furious, thinking that the official is an official and does not think about the people, but wants to please himself.

But Li Yan sent the baby, but Li Shimin looked like he should have been, and even showed a kind expression.

Yuan Yu, who didn't know the inside story, looked at Li Shimin's reaction, and only thought that this was the emperor's joy to get the treasure, and didn't think much about it, just silently waited for Li Shimin to continue to ask.

"You can also talk about the situation in Fengzhou, especially the situation after Li Yan became a guard."

Li Shimin put the glass amphora fine-grained cup on the table and returned to the original focus.

"Back to Your Majesty, General Li Yan ......"

Yuan Yu began to tell the truth what he saw and felt, he said the respect of the people for Li Yan, and the changes in Fengzhou after Li Yan guarded Fengzhou.

All in all, Yuan Yu was praising Li Yan almost the whole time, and at the same time he was also patting Li Shimin's sycophants, saying that Li Shimin had a unique vision and could find talents.

"Nice, nice......"

The more Li Shimin listened, the happier he became, and there was joy in his eyes that could not be hidden.

As an old father whom Li Yan has never met, he can't help but feel proud of his son.

"Worthy of being my son!"

Li Shimin secretly admired in his heart and did not make a sound.

"Your Majesty, there is another thing that the old slave doesn't know whether to talk about or not."

Suddenly, Yuan Yu heard something, a little entangled, and didn't know whether to say it or not.

"What?"

Li Shimin's thoughts were interrupted and he returned to his usual appearance.

"Your Majesty, when the old slave left Fengzhou, it had already begun to snow in the north."

Yuan Yu told the truth, he knew that Hou Junji had mentioned in his letter that there might be a snow disaster in the north this year, so he paid special attention to the snow incident.

"What? It's already snowing in November?! ”

Li Shimin's face suddenly changed a little, and he remembered the warning in Hou Junji's letter.
