When you come to Ordogu City, you can see the dome inside the airport and the huge portrait of Genghis Khan.

Xi Ming remembered the previous history books, and also remembered a news he had read recently.

History says that Genghis Khan unified five tribes and killed countless Tatars and beggars.

Attack the Kingdom of Jin, kill 450,000 in one battle. Conquered Lake Baikal to the north.

In order to avenge 450 people, he sent troops to Arabia at the age of 60. The soldiers were divided into four ways and killed 750,000 soldiers. All the cities that resisted were slaughtered, and more than 1 million people were slaughtered in the first city alone. Jebe led 20,000 men to chase and kill Suduan, but because the Eastern Roman Empire sent money and things, he changed his route and destroyed the Austro-Hungarian Empire, and then went north to Germany and strangled Russia.

On the way back, Genghis Khan was enraged by the treachery of Western Xia, and after breaking the city, he slaughtered the city and killed millions. Before he died, he destroyed the Jin State, and after the death of Genghis Khan, his descendant Wokotai destroyed the Song State.

The destruction of the Western Xia, the Western Xia Kingdom was completely wiped out, and the population of the Western Xia was estimated to be several million, except for the slave mercenaries, all the others were killed.

The destruction of the Arabs was almost all the way to the slaughter of more than 100 cities, at the end of the heyday of the Arab world, with an estimated tens of millions of people killed at 200,000 people per city. The number of invasions of Europe is unknown, but now Europeans hate the Mongols when they talk about them, and it can be seen that there are many massacres.

In that era of ignorance, he was a hero in person, and no one has been able to break the war record of him and his children and grandchildren.

This is his history.

In a recent study, Genghis Khan was called the "greenest" monarch in history, citing the fact that during his reign, he launched many foreign wars and the population of Eurasia plummeted, but because of this, large tracts of arable land were turned back into forests, greatly reducing the amount of carbon dioxide in the atmosphere.

According to foreign media reports, researchers from the Carnegie Institution in the United States conducted this study, and they believe that Genghis Khan led the Mongol army to launch several wars of foreign conquest during the 13th and 14th centuries, conquering vast areas such as the Black Sea coast in West Asia and Central Europe, and creating the vast Mongol Empire. At the same time, due to the shrinking population, arable land has been turned back into forests, reducing about 700 million tons of carbon dioxide to the atmosphere, which can be said to be a "big contributor" to slowing down global warming. While Genghis Khan's approach may be difficult for environmentalists to accept, ecologists believe it may be a historical success story in the fight against global warming.

Julia Pongratz of the Carnegie Institution's Global Ecology Division led the study. "It is widely believed that the destruction of the climate began with the large-scale use of coal, oil and other fuels in the industrial age, and in fact the entire history of human culture has been a process of destroying the earth's ecology," she said. Agrarian cultures began destroying the earth's vegetation thousands of years ago, turning carbon dioxide-absorbing forests into arable land. ”

The Mongol invasion resulted in the absorption of 700 million tonnes of carbon dioxide, roughly equivalent to the total amount of carbon dioxide produced by gasoline use in the world today. The study also estimated the environmental impact of other events involving mass deaths, such as the Black Death in Europe, the fall of the Ming Dynasty in China, and the European conquest of the Americas. These events also played a role in returning farmland to forests, but none of them could be compared with the "effect" achieved by Genghis Khan. "During short-term events like the Black Death and the fall of the Ming Dynasty, the restored forests are not enough to absorb the carbon dioxide emitted by decaying material in the soil," Pengeraz explained. The Mongol invasion was long-lasting, so there was plenty of time for the forest to regrow and absorb a lot of carbon dioxide. ”

Genghis Khan was one of the most conquering and thoughtful conquerors in history, and it was clearly not intentional that his campaign would help absorb carbon dioxide. Pongratz hopes that her research will change the way future historians think about our environmental impacts. "Based on the knowledge gained in the past, we are now making new land-use decisions to reduce the impact on the climate and the carbon cycle," she said. ”

This news is very interesting to watch.

Xi Ming and his party then walked out of the airport.

They chartered a bus to Kangbashi, Ordogu New District.

That's where they're going.

Ordogu is very rich, but only the house is worthless, and it is like the end of the world.

There are more cars than pedestrians on the road.

The houses are all luxury houses.

The driver of the car said that Kangbashi used to run in a hurry, Porsche, Bentley, and Ferrari, and they were determined to surpass one by one; BMW, Ford Mustang, Lamborghini, and Cadillac in the back chased after me, so that they were never willing to be left behind; and Rolls-Royce and Aston Martin, which enjoyed the dignity of the wealthy family, flew here......

At the moment, there are no pedestrians or vehicles driving into the streets of Kangbashi.

Kangbashi New Town, with its high-rise buildings and relatively sparse population, was once dubbed a "ghost town" by the media, but now, after so many years, this new city is still an "empty city".

This ghost domain, which became the birth of China's real estate bubble, once shocked many people.

They ended up staying at the four-star hotel in Kangbashi.

Xi Ming once again took out the investigation materials about Orduo City that Yan Yan handed over to him and looked through them.

Like many people, he sighed that Ordo is really a magical city.

In ancient times there was Genghis Khan. Genghis Khan, a generation of heavenly pride, passed through this place and designated this place as his eternal resting place. The Mongolian place name here is "Ordo", which means "many palaces" in Chinese.

In the dark, it seems that the heavens are predestined.

The houses here are like numerous uninhabited palaces.

But before 2004, Ordogu was the poorest area in Inner Mongolia, and Kangbashi was a desert with only two small villages and fewer than 1,400 people.

Until one day, four "treasures" were discovered here: the unique Albas white cashmere, known as soft gold, the proven reserves of coal of 167.6 billion tons, accounting for 1/6 of the country's total, Orduo is now China's largest coal-producing city, rare earth reserves of 6.5 billion tons, and the proven reserves of natural gas of more than 800 billion cubic meters, accounting for 1/3 of the country's total reserves.

Because of "sheep, coal, earth, and gas", he immediately raised his eyebrows.

After the discovery of the four treasures, the GDP has risen year after year, and the growth competitiveness ranks first in the country, Ordo, with its rich economic strength, built a new city called Kangbashi in a desert.

Three years later.

That is, in 2007, a miracle city was born, and at the end of 2007, the ranking of China's urban competitiveness and development showed that Ordogu ranked first in the country in terms of growth competitiveness, and 10,000 US dollars per capita, surpassing Beijing and Shanghai.

Since 2004, with the rise in coal prices, Ordo, which has 1/6 of the country's coal reserves, has become rich overnight. This place, which Genghis Khan once called "the land of revitalization of declining dynasties and the land of pleasure for white-haired old men", suddenly poured into "gold diggers" from all over the country.

With the influx of foreign tourists, the local government believes that Dongsheng District, the old town of Ordo, is unable to carry more population, and it is necessary to open up a new area to relay it. The place that carries the "Ordo Dream" was chosen in Kangbashi, which is 25 kilometers away from the old city and surrounded by the Ulan Mulun River on three sides.

The wealth from the realization of coal resources has poured out and poured into the real estate industry. With the housing speculation boom, the housing prices in this small desert city have even soared to 20,000 yuan per square meter, approaching the first-tier cities, and the prices have also risen.

The government began to build a new area in the desert, with a total investment of more than 5 billion yuan.

In terms of planning and design, Kangbashi New Area adopts an open mind, selects a wide range of Grade A planning and design units with excellent performance at home and abroad, invites senior experts from the Chinese Academy of Engineering, the Ministry of Construction, Tongji University and other institutions to review and check, compiles and completes the planning at all levels, and forms a complete supporting planning system.

The urban construction of the new area adheres to the idea of stretching, ecology and livability, fully embodies the regional characteristics, ethnic features, grassland culture and harmony between man and nature, and combines the undulating terrain with mountains and rivers, highlighting the uniqueness of the city.

In 2006, the average price of real estate in Ordou was about 1,200 yuan per square meter, and by 2007, the average price reached more than 5,000 yuan. In 2009, house prices rose sharply again, reaching 7,000 to 8,000 yuan per square meter, and in 2010 to 100 million yuan per square meter.

At that time, some high-end residential or commercial properties were sold for 20,000 to 30,000 per square meter.

In 2011, the private lending chain collapsed.

As the coal boom subsided, Ordogu became a ghost town, with unused, unfinished buildings everywhere.

Housing prices fell from tens of thousands to 3,000 in an instant.

In 2012, China's coal exports peaked, with one-fifth of the coal supply coming from Ordo. But by 2014, coal prices had fallen to a six-year low, leading to the closure of private coal mines. Thermal coal, China's main coal product, fell in half between 2012 and 2016 in the wake of the recession.

Fortunately, today's Ordogu still has many advantages: cheap labor, abundant land resources, and most importantly, cheap electricity. This enables Ordou to embrace all kinds of new industries with open arms and turn it into a new economic hot spot.

One of the new arrivals is Bitcoin.

The market capitalization of the borderless digital currency now stands at more than $70 billion, more than quadrupling from the beginning of the year. With such a rally, Bitcoin has attracted the attention of many governments, banks, and small entrepreneurs - Bitcoin is expected to become a new type of digital gold.

Today, Ordogu has developed into a major bitcoin mining center.

The average mining pool uses megawatts of electricity per hour, which is basically equivalent to the electricity consumption of 12,000 households in an hour. Even with discounts, companies spend hundreds of thousands or millions of dollars on electricity bills every day.

Most of Ordo's electricity is provided by the surrounding coal-fired plants. Although coal-fired power generation has a certain impact on the environment, it can provide stable and continuous electricity.

For the people of Ordo, producing bitcoin is like gambling.

Many workers only know that Bitcoin is a virtual currency, similar to stocks, which can go up and down.

In the world of Bitcoin, time is money.

Every 10 minutes or so, the mining machine solves a math problem to determine a winner. According to Bitcoin rules, the winner can win 12.5 BTC. This competitive process is similar to guessing the password of a safe, where there are billions of possible password combinations. The miner who can guess the right combination first will be the first to unlock the safe. In this case, the more machines you have, the more likely you are to win Bitcoin.

Bitcoin miners are creating nearly $7 million worth every day at today's market price.

According to a study published by the Center for Alternative Finance at the University of Cambridge, more than half of the world's largest Bitcoin mining pools are currently in China.

As a result, China has become a dominant force in Bitcoin, a new industry that is expected to change the form of international transactions.

Liu Yanyan provided several bitcoin companies on the profile.

Xi Ming locked the first mining pool in Ordo.

This is operated by a subsidiary of Yanjing Bitmain Technology Co., Ltd.
