The horn whimpered, and all the strong men of the Zasaktu Khan tribe, no matter what they were doing, had to put down everything and immediately put on their arms and rushed to gather.

This is a blue lake. The freshwater lake has long been frozen. The lake ice appears a strange light blue. The color of Lake Baikal is exactly the same.

The people of the Zasaktu Khan tribe were in the north and the cavalry of Ansanxi were in the south. The two sides confronted each other a mile away. They were covered with frozen lakes, and there were some irregular ice cubes on the blue ice, but they were generally flat.

A small amount of snow is mottled on the ice. Because of the wind, there is very little snow on the ice.

Ubud Su Lake is a saltwater lake, the largest lake in Mongolia in later generations, with an area of ​​3,350 square kilometers.

Ubud Suhu Lake, also known as Ubud Suhuer.

The altitude is 753 meters, but the average water depth is only 12 meters, so its water storage capacity is only a fraction of the vast Kusuguer Lake.

Kusuguerhu is not large in area, but very deep, and is a freshwater lake. Its total water area is 2,760 square kilometers, the lake water reserves are as high as 380 billion cubic meters, the average depth is 138 meters, and the deepest part is even more than 262 meters.

The freshwater stored is 1.7 times more than the total amount of all freshwater lakes in China. The water volume is nearly 10 times that of the Three Gorges Reservoir.

If the loss of Lake Baikal is tolerated, it is even more heartbreaking to say that Kusugurhu lost with Outer Mongolia's independence.

China is a country with severe water shortage.

North China and the Central Plains have been an area with alternating floods and droughts since ancient times. Droughts come from the unevenness of precipitation, and often sudden rainstorms and droughts. Floods mainly come from heavy rains and the Yellow River breach.

The storage capacity of Lake Baikal freshwater is as high as 23,600km3, accounting for 20% of the world's total freshwater.

The freshwater reserves of Lake Baikal are eight times that of China's national freshwater reserves, which are enough for 7.5 billion people to use for 33 years.

The annual fishing volume is 3 billion jin. It can solve the problem of eating for the Ming Dynasty's 200 million people.

Eating fish alone can be divided into 15 kilograms per person a year, which is enough to make up for the gap in food shortage.

The water shortage problem in the four provinces of mountains and rivers has been around for a long time, and it has been water shortage since the Sui and Tang Dynasties. There is no way except that the restroom can partially alleviate the seasonal deficiency. It is entirely reliable to rely on the monsoon.

If the precipitation is even, light rain is more, and heavy rain is less, it is a good year. This kind of light rain can seep into the ground, which not only replenishes groundwater, but also is beneficial to the soil moisture. The grain yield will be high. If it is drought and heavy rain, then the harvest this year will be over.

Yang Fan obtained the Golden Finger last time and could use the Future Technology Super Shield Machine three times. He only used it once, which was to dig the Bering Strait undersea tunnel.

This project has begun, and the fully automatic future shield machine has begun construction on the seabed of the Bering Strait.

Yang Fan has sent a railway surveying and mapping team to Liaodong to start mapping the railway route from Vladivostok to Bering Strait. Another surveying and mapping team has already boarded the ship. Their destination is Vancouver Port.

They will map and survey in advance, Alaska on the other end of the Bering Strait, and the railway route to Vancouver.

In the future, the tunnel will be built, and the railways on both sides will be opened. In this way, Asia and America will connect highways and railways. In the future, the Yang family will build railways to Europe, Africa, and America to connect the entire world island.

The Yang family's railway is enough to ensure the Yang family's hegemony.

The Yang family not only needs to control the sea rights of the entire world through fly-scissors and steam engines, but also needs to control the right of road rights of Asia, Africa, Europe and the United States through railways and highways. Only in this way can we have complete arms on the way to control the world.

In addition to the Eurasian Railway, which is currently extending westward, it is the 762 narrow-gauge railway. All railways built in the future will be the modern standard rail railway of 1435.

The rails are all heavy rails of heavy load-load railways that are eliminated by modern times. Erlangzi has found a relationship and can be bought and then transported to Blue Castle Port in the Horn of Africa by sea.

The heavy rails specially used for load-loading railways that have been replaced in modern times are used to run general freight trains, and there is no problem with them for decades.

Modern scrap steel rails are buried and processed on the side of the railway. The purchase price is very cheap and very scrap steel. Because processing is a difficult problem. Because the furnace is complicated and the cost is particularly high, it is better to abandon it.

Yang Fan knew that the Ming Dynasty had come to an end now. The main problem was drought, which was the last straw that crushed the people.

But to solve drought, water must be needed, and fresh water can solve the problem.

After repeated weighing, Yang Fan decided to use the opportunity of the second super shield machine to build an underground water diversion tunnel.

Yang Fan specifically consulted Yao Guang, whether the number of times this super shield machine is limited or the length of the tunnel is limited. Yao Guang checked it and told Yang Fan clearly that it was limited.

The system does not specify the tunnel length limit for each time.

Yang Fan knew that this was a bug.

Since this is the case, Yang Fan naturally needs to make good use of this loophole to the greatest extent.

He used his second chance to build a giant underground tunnel.

From the bottom of Baikal, through the Mongolian Plateau, connecting to the bottom of Kusugur Lake, and then to the tunnel at the foot of Yanshan Mountain. It is used to introduce freshwater from Baikal and Kusugur Lake into the North China Plain. It is used to irrigate the four provinces of mountains and rivers.

From then on, North China and the Central Plains no longer lack urban water and farmland irrigation water.

Lake Baikal is 455 meters above sea level, and its deepest point is more than 1,300 meters below the altitude. From the waist to the North China Plain, it can flow naturally.

Because the altitude of the North China Plain is only a few dozen meters, the imperial capital is only sixty or seventy meters, and Tianjin is even lower.

Yang Fan planned that the inlet of the tunnel was below the altitude and several more outlets were opened. From an altitude of 300 meters to an altitude of 30 meters, this would irrigate the entire North China and the Central Plains. It only takes many irrigation canals to build. Lake Baikal flows out 60 billion cubic meters per year, which is equivalent to the annual water volume of the Yellow River. This era is enough to irrigate farmland. In addition, the water volume of Kusuguer Lake will be enough for the next few hundred years.

If there is no shortage of water in North China and Central Plains, all arable land will be turned into irrigated land and paddy fields. With the ripe wheat and rice, and with bird steak and manure, high yield of seeds, the basic problem of eating can be solved.

At that time, we will find ways to abolish agricultural taxes and corvee services. We will contract infrastructure construction to the engineering team by issuing treasury bonds and bidding. The farmers will never rise up again.

Of course, the problem of land annexation cannot be solved. Yang Fan did not plan to solve it. So, all those who had no land in the future were declared blind in the future, and the whole family took it away and went to Southeast Asia, Northeast China, Western Regions, and Siberia. Give them loans and divide land, resettle them, and live in a new area in the future.

As for those gentry who like land annexation, you can do whatever you want.

Yang Fan was kind. When the gentry could not find the farmer and could only squat in the fields and cried, Yang Fan would promote steam engine agricultural machinery. Large manors and large land systems are the future agricultural development directions of the four provinces of Shanhe River.

An Sanxi narrowed his eyes and spent half a month to finally block all the hostile Khalkhas here.

Now they couldn't run away and were forced to line up on the lake, ready to give it a try and fight the cavalry.
Chapter completed!
