If they could, who wouldn't want their descendants to advance to a higher civilized class! However, Lu Dongzan looked at the vast snow-capped mountains, and after all, he didn't have any confidence in what Sun Xiangfu said.

There is no other reason, there are too many barren lands in Tibet, under such vast glaciers, in addition to relying on external supplies, it is impossible to be self-sufficient, with the planting technology of the Tang Dynasty, and high-yield crops, at best it can only alleviate and alleviate.

Because, no matter how good you are at the crop, you may be killed by a hail of unknown particles after a cloud flies by.

The Tang Imperial Court, if you want to ensure the lives of everyone here, you need to keep sticking money here, because the population is bound to grow and develop, but can the Tang Dynasty itself be so strong forever, and is it still willing to post money to this place?

He is not a person who does not understand the history of the Central Plains, especially in the past two or three hundred years, the Central Plains Dynasty has changed regimes very frequently, it can be said that it is not as stable as their Tubo, at least, Tubo passed to Songtsen Gampo here, it is the thirty-third Zampu, hundreds of years, there are no subversive changes.

Seeing Lu Dongzan's impossible expression, Sun Xiangfu said again, "I know you still have doubts in your hearts now, but I will use facts to dispel your doubts." ”

Lu Dongzan asked, "What are you going to do?" ”

Sun Xiangfu smiled and said, "It depends on what you lack in Tubo, what you lack, I will let what be produced here, the problem, isn't it solved?" ”

Lu Dongzan said, "We lack food, wood, fuel, livestock forage, salt and iron, and clothing here······

After he finished saying a series of things, Sun Xiangfu smiled and said, "Actually, you originally lacked nothing here, but because you only know how to cut and consume, but you don't know how to plant, you have a shortage of everything here."

Hundreds, thousands of years ago, these low cols must have been overgrown with shrubs and even trees! But why not now? It's your survival mode that pushes you to the brink of extinction. ”

To say that all of Tibet is like Tanggula Mountain, where the altitude is more than five or six thousand meters, then it is not true, the places below 4,000 meters above sea level here, at least half, and the places below 3,000 meters account for one or two percent, in many places below 3,000 meters above sea level, there are at least seven or eight months a year, there is no snow freezing, the temperature can even be comparable to the Central Plains, all kinds of trees and shrubs that can be planted and grown in the Central Plains can grow to a large size here.

Moreover, at an altitude of 3,000 to more than 4,000 meters, trees can also be planted, and such places will not freeze all year round, and there are snow water melting on the mountain tops for several months in summer, constantly nourishing the land, allowing the aquatic plants here to grow for their cattle and sheep to eat.

Where even aquatic plants can grow, let alone trees, Siberia, perennial frost and snow, there are still large areas of primeval forest, that is because there is no one there to cut down a lot of wood and burn wood to keep warm.

As far as Sun Xiangfu knows, there are many trees suitable for growing in such plateau areas, such as cold shirts, cloud shirts, alpine oaks, alpine pines, ginkgo, white birches, camphor trees, etc., and there are even more, and some can even produce a lot of economic value, such as camellia trees, alpine rhododendrons, etc.

Of course, these things really want to grow up here in patches and change the environment here, at least like Shanyang's side, for more than ten consecutive years, a lot of manpower has been invested in planting, and even, it takes one or two generations of growth to see some results.

However, Sun Xiangfu still has a recipe, if it is just some food, clothing and other condolences, with the current abundance of materials and the development of industry in Datang, he can't afford to spend two or three months to prepare.

Among the things he brought over, there were first 20,000 sets of solar pots, cooking pots, and stoves. Subsequently, every three months, another 20,000 sets will be shipped.

Don't underestimate these things, a family, with it, almost half of the year, there is no need to make a fire to cook rice or boil water.

Because, despite the cold weather on the plateau, however, the sun is very abundant, especially in a few low-lying habitats, there is rarely a continuous heavy rain season, as can be seen from their red skin exposed to ultraviolet rays.

Therefore, even in the era of advanced science and technology and sufficient supply of coal and gas in later generations, the local people still use a large number of solar pots to boil water and cook rice, which is very energy-saving and environmentally friendly.

As long as this kind of pot stove is popularized to all Tibetan families in the future, then they can save at least three or four percent of the fuel used to cook meat and water.

In addition, Sun Xiangfu brought enough seeds to plant more than 100,000 acres of corn, sweet potatoes, potatoes, soybeans, cotton and other crops.

They are not only high-yielding, but also better than the barley, wheat and other crops now grown in Tibet, such as corn, cotton, and soybean bellflowers, and are also good fuel for firewood.

Anyway, after a certain amount of relocation, the entire Tubo, will not exceed 200,000 households, with solar pot stoves, plus these bellflower fuel, can basically supply them more than seventy or eighty percent of the fuel, at least, no longer need to cut down trees, dig shrub roots to heat, and even, can save a lot of cow and sheep manure, used to drain fertilizer, fertilizer fields.

Then, at the same time as not cutting down trees, every year, add a certain number of tree planting, there will be more and more woods here, a few decades later, just by pruning and cutting firewood, it is enough for many people to heat, of course, at that time, there is not necessarily a need to rely on firewood for heating, because the times may have advanced to the extent that coal can be mined, or natural gas as fuel.

It can be said that now as long as the problem of Tubo planting is solved, their fundamental problem is solved, and scientific means are used to adjust the ecological balance, not to mention the Tubo people in this period, that is, the Han people, it is impossible to imagine, that is, Sun Xiangfu, a traverser, has always stood on the side of the scientific view from the perspective of thinking, so when the problem comes to him, it will become very simple and directional.

Just by talking, Lu Dongzan can't understand how people can change the world, so Sun Xiangfu didn't bother to explain to him more, just let him watch what he did.

After some busyness, the large team of 30,000 or 40,000 people finally settled down.

In Sun Xiangfu's conservatory, the pressure cooker is suddenly rushing to the heat, this thing is still Sun Xiangfu after receiving Li Shimin's holy decree, he sent a letter to Marseille to make them specially built, otherwise, they will have to eat half-baked things like the Tubo people, but unfortunately the time is limited, and they can't build more, just a dozen.

Therefore, these pressure cookers are estimated to be used for several rounds, specially for female members with severe altitude sickness, to make some easily digestible nourishing soups, male league members are unbalanced, and they have to endure it, who is called the more gentlemanly Sun Xiangfu who leads the team!

A pot of chicken and lion's mane mushroom soup, and a few pieces of wild ginseng in it, even if you can't eat anything, drinking a bowl of this stuff will be enough calories for your body.

After eating, Sun Xiangfu rested early, and as long as they didn't go to a place above 4,500 meters above sea level, their headache would become more and more slight until they didn't feel anything.

At dawn the next day, Yu Xiu'er, who got up earlier, was obviously in a much better mental state, but she suspected that the watch on her wrist was broken, and she was looking for Li Xiangdie and Yao Hongsleeve to match the time.

Because it was just dawn tomorrow, the hands on her watch showed that it was almost nine o'clock in the morning, and what made her even more strange was that Li Xiangdie and Yao Hongsleeve's watches were also like this, so Sun Xiangfu was woken up by her when she pulled her wrist to look at her watch.

"Don't look at it, the watch is not broken, it's where we are, the time zone is different, it's usually almost nine o'clock in the morning, and in summer, it's even dark at ninety o'clock in the evening, which is different from Shannan Road." Sun Xiangfu withdrew his wrist and said.

Yu Xiu'er asked puzzled, "Time zone, what is it?" ”

Sun Xiangfu said while getting dressed, "This has to talk about some astronomical knowledge, the world we are in is spherical, this point, Li Daochang has proved, then, the reason why there is sunrise and sunset, is because our spherical world is rotating, it rotates in a circle, it is a day, and with its rotation, there must be a place where the sun shines first, and then a place where the sun shines."

Here, we are illuminated by the sun later than Shannan Road, and in Liaodong, Wuzhou, it is illuminated by the sun earlier than Shannan Road, so with the same watch, when you are in Liaodong, when it is dawn, you will find that it is only more than five o'clock, but in the Tubo Plateau, it is more than eight o'clock, and in summer, when the day is long and the night is short, it is more obvious······

The existence of the watch can prove the rotation of the earth, this problem, Sun Xiangfu once wrote to the Anxi Metropolitan Protectorate, to explain to the ministers who felt that their watches were broken, and now, it can be regarded as letting his daughter-in-law feel the magic of this world.

However, it is impossible for Yu Xiuer to understand what it means that human beings are actually sitting on the ground and flying at a speed of more than 10,000 miles per minute, because Sun Xiangfu later said that the world revolves around the sun, and the sun revolves around the Milky Way, and at a speed of more than 200 kilometers per second.

As for why you use a pressure cooker to cook rice, the kitchen worker who got up this morning to cook has realized it.

If you cook rice in an ordinary pot, you have to take a long time and add a lot of water to cook it into porridge.

Otherwise, according to the cooking method in the Central Plains, the rice is hard, at this altitude of four or five thousand meters, the boiling point of water, only more than 80 degrees, with boiling water to soak a food factory of instant noodles are laborious, not to mention those chopping a large piece of beef and mutton in the city, the people here do not have the habit of eating cooked food.

This kind of knowledge is simply magical for people who don't understand it, and those who understand it will think of using methods to restrain it, and the temperature of the steam is relatively high, so the staple food of the Xuanfu team this morning is steamed buns and steamed buns.

Sun Xiangfu's breakfast is noodles pressed in a pressure cooker, mixed with some sesame oil, and with his homemade chili sauce, a man and three women eat fine sweat on the nose, chili pepper This thing can forcibly open people's sense of taste.

Now, it's not Sun Xiangfu who is good alone, Yu Xiu'er and they usually eat some, and after their bodies relax a little, they have to have some food in their stomachs to feel alive.

When the snow on the cliff top in the distance under the strong light was scorching, the two or three thousand people of Su Biru around Naqu City were brought to the open space in front of Sun Xiangfu's residence, most of them were wearing clothes like oil shells, and their bodies had a smell heavier than that of cattle and sheep, and their skin was black and red, and they were young men in their twenties who were in the prime of life, and they looked older than the thirty-four-year-old middle-aged people in the Central Plains.

The art troupe has a stage that can be quickly spliced and built, and after the wood is unloaded from the ox cart, a wooden platform more than one meter high and three or four square meters is soon erected.

After Sun Xiangfu appeared on the stage in a ceremonial costume, he originally wanted to recite it according to Li Shimin's holy decree, just like when Lawyer Pei and Daniel Zhang went to Happy Village.

But then I thought about it, among these people, there were not a few people who could understand the Chinese vernacular, so what were they reading, but they just pretended to open the holy decree and said, "His Majesty the Emperor of the Tang Dynasty said that under the rule of the Tang Dynasty, no one like you is allowed to be as poor." ”

Then he received the decree and said, "So, congratulations, you will soon become rich." ”()
