I am engaged in construction in Datang

Recently, more and more people have come to Chang'an to work, and the progress of low-rent housing is even faster than that of heaven on earth.

People don't need to paint the walls and can just live in the bare house, which they feel is much better than sleeping in the open air.

But why was the window so big? Fortunately, the woman covered it with newspapers.

Li Yin squatted beside the fields in the village, pinching the wheat seedlings.

"The powered water truck has been put into use. People no longer have to work hard to irrigate the fields. The seeds selected from the 8% and 11% salt water concentrations appear to be the best. We have to wait and see how we can crossbreed them. There are not enough varieties..."

Li Yin unconsciously pinched off a wheat seedling and stuffed it into her mouth.

"Bah bah bah!"

"Master!" Li Xiaoyang ran over and saw Li Yin's mouth full of green juice. He forgot what he wanted to say.

"What's wrong?" Li Yin went back to rinse her mouth. Fortunately, she was eating wheat seedlings.

Li Xiaoyang came back to his senses: "The chain is made."

As soon as she finished speaking, Li Yin ran away. Li Xiaoyang had no choice but to follow her.

Really, when will the owner of the manor be more stable?

"Where is the chain? Where is the chain?" As Li Yin entered the factory, she ran around with shining eyes.

Li Yin thought of the natural science class when she was a child. The teacher talked about the important role of chains in transmission. Li Yin wrote down the role of noodles in transmission in her notebook. She couldn't understand why noodles belong to mechanical transmission.

Later she realized that she was not cut out for engineering.

"Master, this way!" Zhao Erniu was carrying a strange-looking object and waved to Li Yin.

Li Yin ran over and looked at the wooden product in front of her: "Bicycle?"

Zhao Erniu nodded: "It's a pity that it's too heavy. Riding it is not as fast as walking, so I just carried it on my back."

Wouldn’t the wooden one sink to death?

"What do the iron and steel mills say? Have the molds been made? Can they make bicycles?"

"It will be done soon, three days at most." Zhao Erniu was extremely excited when talking about this.

This is a vehicle that does not require animals to pull it and can run with human power only!

You can travel sixty or seventy miles in an hour, and it’s not tiring!

"What a pity, there is no rubber." Li Yin felt uncomfortable. These days, getting rubber is harder than smelting iron and steel. She has been purchasing it from all over the country these days. Maybe someone happened to bring it from overseas?

Then they would refine some animal skins and use them as they pleased.

She thought about using dandelions to make rubber, but the refining of n-hexane was too difficult and the rubber yield was low, so she gave up this method of refining rubber at that time.

In fact, there is another plant called guayule that can be used to make rubber. During World War II, the United States controlled the rubber producing areas, and people used guayule to make rubber.

But the problem is that the invasive species of guayule has not yet arrived inland, and Li Yin does not intend to let it come over.

As for artificial synthesis, it is even more impossible as the technology is not up to the task. It would be simpler to just go to South America and bring some saplings.

"Without rubber, nothing can be done!" Li Yin took a deep breath, feeling a tightness in her chest. "Forget it, it's better to smooth the road first than to wait for rubber."

The excitement gradually cooled down. Li Yin asked Li Yi and Li Er to remember this matter and send a few bicycles to Li Shimin in two days. The road in the palace was flat and there would be no need to worry about hurting their butts. They could also ask him when he would come to the farm.

Time flies by in the busy time, and the Dragon Boat Festival is approaching in the free time.

It’s time for the students who took the second-class certificate exam to go home.

Students who passed the first-class exams still had to continue studying, but during the Dragon Boat Festival, Li Yin gave everyone a three-day holiday so that they could go back and reunite with their families.

Of course, there are also students who come from far away and choose to stay overnight. The women’s village will still send people to guard and sell boxed lunches to ensure everyone’s daily living needs.

There were also banquets in the palace, which were more magnificent and grand than those at the women's farm.

The frontier of the Tang Dynasty.

"The long clouds from Qinghai darken the snow-capped mountains, and the lonely city looks towards Yumen Pass in the distance..." Li Xiaochun looked at the city in front of him, which was covered with endless yellow sand and desolate.

"I'll wear my golden armor after a hundred battles in the yellow sand, and I won't return until I conquer Loulan." Zhao Zhonglang rode forward and stood side by side with Li Xiaochun: "Master Li, once we leave Yiwulu, we are no longer in the territory of the Tang Dynasty."

"We have to rest here for one night, otherwise we have to sleep in the wild." Zhao Zhonglang continued.

He was the General of the Central Army who had been guarding the manor. He was familiar with the people in the manor and had a closer relationship with them. This time when Miss Xiaochun traveled west, she asked him to lead the team to guard the manor.

"The Silk Road has been cut off now. I am leaving the country as a smuggler and cannot stay overnight."

Li Xiaochun tightened his hood, the wind and sand whistled and went straight into people's sleeves: "Zhao Zhonglang, contact the informant and leave the customs tonight."

Zhao Zhonglang sighed and had to agree.

The young ladies in this village are more vigorous than him.

A total of five caravans were sent out this time. The Western Regions is too large, and one caravan is not enough to complete the tasks assigned by Li Yin.

Li Xiaochun only needs to take charge of the overall situation.

Zhao Zhonglang took out a flute made of thin bamboo, and soon, the sad and melodious flute sound hovered in the air.

The convoy moved forward slowly, and a secret door at the checkpoint opened.

Li Xiaochun led his men in.

Before Zhao Zhonglang's flute music had stopped, another more mournful flute sound came from the city wall.

After listening to the flute for a while, Zhao Zhonglang turned to Li Xiaochun and said, "Let's go."

Everyone pulled their hoods tight and wrapped themselves up so that the soldiers guarding the city would not see their appearance.

They are smugglers.

On the city wall.

A group of gray-haired veterans pulled their bows with both hands and silently watched the receding backs of Li Xiaochun and others.

The Silk Road has been cut off for several years and this place has become deserted. Only a few thousand old, weak and sick people are left to survive, and the main force of the army is not here.

The higher-ups wanted to replace them with younger people, but they refused.

At this moment, the people in the Western Regions are as obedient as grandsons. They are frightened by being beaten by Your Majesty and are begging for marriage all day long.

There is no need to waste time on the little ones. They are a group of veterans, enough to scare the Turks into submission. (In 627, Li Shimin built Longyou and penetrated into the Western Regions. In 640, he completely controlled the Western Regions and built the Anxi Protectorate.)

"Lao Ya, where did this team come from?" The old man took off his arm strength and turned his shoulders twice: "I'm too old to do it."

"He's from the all-knowing world." Glancing at the other person, Da Ya grinned happily: "This one is really good at pretending! Why is the leader a girl? Isn't she going to marry another prince?"

"No way?" The old man was suspicious. Why would they set up a caravan for a marriage alliance?

"Who knows? They are so stubborn. If I were to say so, I would beat them until they tremble at the mere mention of my name!"

"Come on, you're just talking nonsense..."

The north wind howled loudly, and soon the caravan was reduced to the size of an ant.

"Today is the Dragon Boat Festival." Li Xiaochun turned his head to look at Yiwulu City behind him and took out a few colorful ropes from his pocket.

"The owner said that during the Dragon Boat Festival, there are many people and adults are afraid that children who go out to play may get lost, so they tie a red string on their wrists to make it easier to find them."

Li Xiaochun turned his head and looked at Zhao Zhonglang and the others: "Do you want one?"

"The desert is dusty, don't let your family lose track of you."
