"It's so beautiful." Princess Yongmu looked up at the fireworks and only uttered four words in the end.

Li Yi faintly heard the sound of fireworks, looked at the location of the imperial city, and suddenly remembered something important.

He waved to Qingsong and shouted: "Send people to send fireworks to the east and west cities of Chang'an and the south of the city, set off there, quickly." ”

Qingsong ran to find someone, and Li Yi breathed a sigh of relief.

He thought that it was not easy for the people to watch fireworks, and when they went to the imperial city from other places, they obviously couldn't squeeze in, and some people could only watch the show in their own workshop.

The location of the east and west cities is suitable, as long as the fireworks fly high enough, the people in the surrounding areas can see it.

There are many officials and ordinary people in the south of the city, and they also want to see it.

Li Yi believed that some people would run to the river to watch Zhuangzi's fireworks, and they would not close the city gate and could go back at any time.

Yu Lin Fei rode with fireworks and hurriedly ran around the south of the city to the West Market, and the roads in the city were full of people.

A quarter of an hour later, the fireworks in the Imperial City and Zhuangzi had not stopped, and the fireworks in the East City began to rise into the air and bloom.

After another quarter of an hour, a beautiful pattern also appeared in the sky above the West Market.

As Li Yi thought, many people outside Bashui stood there and watched, and ate dumplings by the way.

The people in the Honglu Temple looked at the prosperous scenery of the Chinese New Year's Eve of Chang'an in the Tang Dynasty, and their mood was not good at all.

After more than an hour, the fireworks were over, and the performance continued in the imperial city.

Isimba's face was full of helplessness: "Sledding, there is snow in many parts of my Tibet all year round, and it snows for many days every year. ”

"It also snows in the Turkic places, and there are also steppes and Khitan places."

Bo Yan had already thought of the sleigh transportation capacity of the Tang Jingzhao Mansion, and even more thought about its military use.

"Write back so that we can use the same tools there." Isimba's tone was full of helplessness.

Tubo always chased after him to learn Datang, and the hot air balloon still didn't learn how to use it, and the alcohol was gone.

At the moment, there are only kerosene lamps, which are expensive, and they do not sell more kerosene.

The hot air balloon program is not working now, and the only way is to think about how to deal with Datang's hot air balloon.

Steamships can be learned, but they are of little value in Tibet.

The rest were sleds, pulled by horses and loaded with baggage.

Instead of horses running with their baggage, there is a noticeable difference in the weight that horses carry between the two.

"It's easy to transport in normal times." Bo Yan knows this very well, and the people of Jingzhao Mansion are doing it like this.

Last year's winter, or the winter of the year before the end of the year, snowed heavily, and the people had to travel in ox carts and horse-drawn carts in winter.

When you encounter a snowy place, take off the board from the car, prop up the wheels, and slip over.

Then it changed, all sledding, no snow had to be cleared from the road.

If you think the road is not easy to walk, you will take the water network, and the people will come and go frequently.

In this way, the surrounding counties were contacted and a large number of greenhouse vegetables were transported.

I don't know if greenhouse planting in Tubo is easy to use? You need a lot of silk, and you have to add fire.

Thinking about learning from the Tang Dynasty to grow greenhouses, Bo Yan suddenly thought of a key question, how to burn Tibet without coal? Burning firewood and cow dung?

Just to eat some cucumbers and eggplants in winter, I invested a lot of money, and some people don't have silk clothes to wear in winter.

Including slaves, slaves who do not give clothes will freeze to death, which is a property loss.

"Growing soybeans to raise insects...... Bo Yan thought about learning bean insect farming, and he found that the insects were delicious.

Even if the upper class of Tubo doesn't like to eat, just give it to the slaves, and the slaves can work more if they have the strength.

"If Li Yi is from Tibet, what good way will he come up with for Tibet? Specially suitable for Tibet. ”

Isimba was thinking about Li Yi, he was going to come over to compete with Li Yi and take the technique from Li Yi.

He is conceited and thinks he is strong.

After a series of things, the competition was gone, and he kept watching Li Yi take things out.

So Li Yi is in Jingzhao Mansion in the Tang Dynasty, and the things he thinks about are the local people, what should he do if he changes to Tubo?

"No...... Yes, it's called resources, there are no resources, he can only provide a short plow in Tubo, and the sleigh can be taken out, what else? ”

Bo Yan felt uncomfortable when he thought of Li Yi, and he belittled him, and his mood was much better.

The other foreign envoys in the Honglu Monastery were studying hard.

The Xi and Khitan lived in the northeast and part of Inner Mongolia, and their winter journeys were difficult.

They found that this sleigh was good, and they were actually not mistaken, and the horse-drawn climbing plow, deer-drawn climbing plow, and dog-drawn climbing plow in the Northeast region in history were this thing.

As long as there is snow, the plow can go up the mountain, and where the horse can run, the plow is guaranteed to walk.

The bushes were too dense to trip the horses' legs, and the plough could fly over them.

Of course, in general, I don't play so much, I feel sorry for the horse, in case I fall.

They hadn't thought about it before, but this year, watching the people of Jingzhao Mansion come and go, they were ready to learn.

Otherwise, after heavy snowfall, you won't be able to go out at all.

Yu Jiang came back with the team that went to Khitan and Bohai, still pretending to be Shudi.

On the bright side of the Khitan team's steward is Bacharcha, and Yu Jiang found Bacharcha.

Bacharcha and his entourage brought back all their families, including the family of the brother who didn't go, and planned to let the family live in Datang.

Mainly children, learning the culture of the Tang Dynasty, and then they took turns to return to the Khitan to help with ideas.

"Bacharcha, the sleigh looks good to make, but in fact, there is a doorway inside, and the Khitan needs the sled." Yu Jiang pretended to eat dumplings and communicated with Bacharcha.

"I'll ask." Bacharcha is dedicated to the sake of the Khitan, no matter if it is thirty today.

Li Yi had just sent Princess Yongmu back to the courtyard and was about to go back to his yard to rest, when he met Bacharcha, who had come over.

There was also Yulin Feiqi accompanying him, and Yulin Feiqi was not worried about other people approaching Li Yi.

"Proprietor Li, what's the trick to sledding? I Khitan need. ”

Bacharcha asked loudly, and there was a sound coming from the performance over there.

"You mean production? The main thing is lightness, because there is no bamboo over there, it is better to make oak wood, and it is relatively heavier, if you want to be lightweight, use straw, and weave oil tree strips into rows below......"

Li Yi did not refuse Bacharcha's question, and patiently explained how to climb the plow in the Northeast before.

The light one is not strong enough, and there are children who need to carry, or load a little goods, and people drag them away, using that one.

If you use wood, you naturally have to use livestock.

"There's a deer over there that pulls the plough instead of a horse, and they're more docile." Li Yi also kindly introduced the reindeer.

The entire Northeast is under the control of the Bohai Sea, including the Heilongjiang area, and the control is actually not very strong.

The three northeastern provinces, Liaoning and Heilongjiang are far away, how can the entire region be completely controlled? With the highway? Darts? Train?

There are many mountains and rivers along the way, that is, some places are nominally under the control of the Bohai Sea, but in fact the local tribes live on their own.

Otherwise, in the autumn, it was said that there was a rebellion, and the news reached the ears of the king of Bohai, and the army was sent in winter, but it did not arrive in the spring, and a group of people froze to death on the road.
