The village next to the Phoenix Valley is located relatively high, even if it is halfway up the valley, so even if there is a natural disaster such as a flood, it will not have much impact on the village, and it is said that the village was under the valley before, although it is more convenient to get water, but in more than a thousand years, there have been many floods, causing great losses to the village.

After that, the people in the village moved the village to the halfway up the mountainside, usually fetching water to go down to pick it up, and it took two moments to come and go, and it didn't take a long time, in addition, in addition to the crops that can be planted in the valley, they also planted crops in the middle of the mountainside, but the crops in the middle of the mountain can never be compared with the crops in the valley, but it is better than no harvest, in addition, if there is a flood, the crops in the valley will not be harvested, so, the crops in the middle of the mountainside, It can be used as a life-saving ration for the villagers.

For more than 100 years after the move, the village has been home to fruit trees and corn in the middle of the mountainside, fruit trees are drought tolerant, as long as it is not particularly drought, there is no need to water the crops, and corn is also drought tolerant, the best of all crops, and even, the high-quality land in the valley is sometimes grown with corn.

However, the yield per mu of corn is relatively low, no matter how developed science and technology are, corn can not reach too large a yield per mu, so the local people have been living very poor, and they can barely get by.

However, with the arrival of Li An, the situation here has changed for the better, the local halfway up the mountain is no longer planted with corn, but to plant drought tolerance and barrenness tolerance, and high yield of sweet potatoes, corn, peanuts, potatoes and other foreign food crops, which can not only greatly improve the yield of crops, but also more varieties of crops, and different crops are rich in different nutrients, eat more different kinds of food, which is more beneficial to people's health, so, in recent years, The life of the local people has improved greatly, at least, it is much better than before, and the spirit of the people has also improved a lot, and everyone is happy, often putting a smile on their mouths.

No, Ang Lee and a group of guards stood on the mountain bag, and they all walked over warmly, which was enough to show their hospitality and friendliness.

Looking at the appearance of this white-bearded old man, Li An can initially estimate that he is about seventy years old, according to the standard of seventy years since ancient times, this is already considered a long life, and the few old men who followed behind him also looked like they were forty or fifty years old, and there was a twenty-year-old young man, who was responsible for supporting the seventy-year-old man.

"Good afternoon, old man!"

Ang Lee opened his mouth to greet first.

"Hello nobleman, where is the noble man from, where is this going!"

The white-bearded old man asked.

Li An replied: "We are from the capital, we are going to Xiazhou, passing by here and feeling that the scenery is quite good, so we stopped to rest." ”

"Oops! What a long train! There are so many soldiers, and the position of a noble person is not small! The little old man is polite. ”

The white-bearded old man walked up to Li An, saw the train parked on the tracks, and saw a large number of Tang soldiers nearby and in the distance, and was naturally quite surprised, he lived for such an age, although he had seen some of the world, but because he had never left the county, so, the biggest official he saw was the county order, and Li An's pomp and circumstance obviously exceeded the county order, far more than the county order, so this old man can be sure that Li An's position is above the county order, but the specific position, he can't know, The few behind him are also honest farmers, and they are all people who have been to the county seat, and their knowledge is relatively average.

"Oh, how big does the old man think of my position."

Li An asked curiously.

"Little old man doesn't dare."

The white-bearded old man looked a little nervous.

Li An opened his mouth and said, "Old man, please take a seat!" In fact, the size of the official position is also irrelevant, no matter how high my official position is, it is the same as the old man, and they are all people who work for the Tang Dynasty, but our division of labor is different, I am responsible for handling the major affairs of the country, and the old man is responsible for leading the people in the village to grow food, everyone is equal, it is the same. ”

The white-bearded old man didn't dare to sit down, listened to Li An's words, and hurriedly said, "The noble man said that he was laughing, how can this be the same?" What you do is a big thing, and what the little old man does is a trivial thing, which is too far away to be compared, not to be compared. ”

"Yes! The old man naturally can't be compared, but there are thousands of people in the world who work hard like the old man, and so many people together have contributed far more to Datang than me! It is with thousands of people like the elderly that our Datang can be so strong! So, every ordinary person is great and cannot be ignored. ”

Ang Lee said with a smile.

When the old man heard it, it seemed that this was the case, if all the people in the world did not listen to the orders of the imperial court, then the imperial court would exist in name only.

"Xiao Lao'er has lived for most of his life, and it is the first time that he has heard that a useless person like himself can have such a big effect, Xiao Lao'er is very happy!"

The old man said happily.

Li An smiled, looked at the environment of the valley, and said, "The village is located halfway up the mountain, and the ancestors have wisdom!" If it is located at the bottom of the valley, it will be very dangerous in the event of a flood, but it is better to be located in the middle of the mountain, and you will never have to worry about flooding, and it will be quieter. ”

"What the noble man said is that more than a hundred years ago, our village was still under the mountain, and then it was moved to a higher place in order to avoid floods and military disasters, so although it was a little inconvenient, but safety is the most important, by the way, a large piece of the village was densely packed with fruit trees before, and many could flood the entire village, standing here is absolutely impossible to see the village, only step by step into it, you can see the village, passing officers and soldiers are too lazy to find, or unwilling to walk such a long way, so, in the valley directly passed, Even if you stop to rest, you are not willing to run a little longer to get to the village, so that the village is safer and not easy to be destroyed. ”

The white-bearded old man opened the door to the reason for the relocation of the village.

It turns out that this small mountain village is to avoid floods and military disasters, only deliberately moved to the middle of the mountainside, in the troubled times, as long as the villagers are careful, it is not easy to be found, after all, there are so many fruit trees, the sight of the village is well blocked, and the village is not rich, even if the thieves rob, are not willing to rob such a poor village, there is nothing at all, this village except for some useless farm tools and basic furniture, there is nothing valuable at all, and there will not be a lot of food, I really couldn't find a reason to rob.

After chatting for a while, everyone was familiar with each other, and several old men politely invited Li An to sit in the village, and Li An couldn't agree because he couldn't stay too long, so he refused the old man's kindness, and distributed the delicious snacks prepared for himself to the children who ran over, these children were very cute, and after eating the delicious food that Li An gave them, they ran around happily, and even, there were bold children, who actually dared to provoke the guards next to them, but the guards' eyes were deliberately staring, and the children were scared, so frightened that they quickly ran away, And no longer dare to be presumptuous.

Originally, I was going to have lunch on the mountain bag while looking at the beautiful scenery, but my own food was given to the children for the tooth sacrifice, and it seems that I can only eat it in my own car after getting on the train.

"It's not early, we're leaving, a few little guys are coming, and these candies are for you."

Ang Lee stayed on the mountain bag for less than half an hour, said goodbye, and gave all the candy used for sweet mouths to the children around him, these children are so cute, Ang Lee likes these children very much.

"Noble, this is our local product here, please bring some! It's all a little bit of our heart. ”

The white-bearded old man picked up a few baskets of sustenances and spoke.

These local products are also very simple, mainly native eggs, and some unnamed medicinal materials and ingredients, in the eyes of the countrymen, these are worthless things, but these things are sent to the capital, the price will not be low, maybe it will be very high, after all, the price of the capital is too high, in the local worthless eggs, transported to the capital can at least triple the price, after all, transportation in the past is not an easy thing, freight accounted for a large part of the cost.

Since this is a piece of the villagers' hearts, Li An naturally did not refuse, and accepted all the orders, but when he left, he gave them some practical gadgets, a few mirrors, and a telescope that they absolutely couldn't afford, which was given to their village collective, and whoever likes to play and play with it.

The white-bearded old man had never seen a telescope in his life, and when he used it for the first time, he saw something far away, and he was amazed and couldn't put it down, but he was soon snatched up by more curious children.

In the midst of a farewell sound, Li An and Li Hanlu got on the train, and the local villagers all gathered on the small dirt bag, looking at the direction of the train leaving.

Among the local specialties received, there are local eggs, and at that time people made poached eggs, the taste is no different from the eggs in the capital, but the mood is different, after all, this is just sent by the people, there are feelings in it.

The Phoenix Valley is not very long, and the speed of the train is very fast, soon, the beautiful Phoenix Valley ran behind him, after a period of time, the vehicle has passed through Yijun County and Shengping County in Fangzhou, the economic situation of these two places is naturally worse, here is farther away from the capital, the loss of population is also quite serious, young people, almost three percent of them went to the capital to mix, leaving behind are no people, and some old, weak, sick and disabled.

The further north you go, the more desolate the scenery on both sides of the road becomes, and the sense of desolation will make people uncomfortable and make people's mood heavy, fortunately, Li An and Li Hanlu are both from the north, and they have stayed in places that are more desolate than here, so they naturally don't care too much about the desolate scenery along the way.

The speed of the vehicle is not fast or slow, it has been moving at a constant speed, the carriage is relatively stable, and there is no sense of bumps, after all, the speed is here, and you can't bump if you want to.

In the large living room of the carriage, there is a large table, this table is specially prepared by Li An, there are several small drawers under the table, and inside each small drawer are slow down various items, mainly paper, pens and rulers, as well as the most basic tools such as compasses.

The purpose of preparing these is to be able to look at calligraphy, paintings, drawings and drawings when you are bored, kill the boring time, and make yourself happier.

In fact, you don't need a big table to read a book, but drawing is different, some drawings require professional tools and professional drawings, and the volume of these things is not small, a small table can never be put down, there must be a large table, so that it is more convenient to draw pictures.

Li An finished lunch and rested for half an hour, and at the moment he was idle anyway, Li An felt that he could use this spare time to do some serious things, which is the so-called drawing, to draw the drawings that Datang needs.

These drawings can be mechanical drawings, architectural drawings, furniture drawings are also possible, there are a lot of fresh things, are constantly improving, the more you improve, the better the quality of the final production, such as many machines, when they first came out, they were strange, but after a period of improvement, the machine will become more and more advanced and beautiful, looking at it is a beautiful landscape, and most of this is the credit of Ang Lee, of course, there are also those skilled craftsmen, But Ang Lee's contribution is undoubtedly more and more effective, there are many things that only Ang Lee can do, and it is difficult for other craftsmen to do well, and they don't even know where to start.

This time, the drawings to be drawn by Li An are the drawings of the underground road, that is, the underground passage of Chang'an City, before drawing, Li An must first carefully look at the plan of Chang'an City, and mark the symbols in some crowded places to find out the most reasonable underground passage route, and then the drawings can be drawn.

The area of Chang'an City is too large, and the large residential areas outside the city are not counted, just the area in the city is already large enough, and there are more than 100 squares in the city, and there are more roads composed of these squares, among them, there are twenty or thirty main roads, among them, the north-south and east-west roads account for half, as for the roads in the square, there are even more boundless.

So many roads, if all the construction of underpasses, the amount of work is too large, it is certainly unrealistic, can only be selectively built the most urgent and important roads, and then expand when the conditions are ripe.

What Ang Lee has to do now is to select these roads, then design them in detail, and build them into a model road considering all aspects of this underpass.
