The rise of nanometers

the next day.

After getting up, Julie and Vivian, led by Zhang Lei and Hall, visited various tourist attractions near Chang'an.

After traveling in Chang'an for a few days, Julie did not go to tourist attractions all the time. She also took the time to go to ordinary residential areas and streets and alleys for an in-depth stroll.

She discovered that the Eastern world she saw with her own eyes was completely different from the Eastern world described by Western media in the past.

This huge gap made Julie's inner doubts even more obvious.

August 2nd.

A train departs from Chang'an and heads to Ning District in the north.

Julie and Vivian said goodbye to Zhang Lei and Hall, and took the train to Ning District. They wanted to go to the vast and desolate Tengger Desert and the extinguished Helan Mountain to see if it was like the news reports.

Leaning against the train window, Julie looked at the scenery on one side, which changed little by little as the train moved forward.

Unlike the southern part of Qin Province, which is densely populated with scenic spots and historic sites, the further north you go, the loess slopes are criss-crossed with ravines, and the vegetation types also change significantly.

Unlike the Qinling Mountains near Chang'an, which has dense mountain forests, the vegetation on the loess high slopes is a mixture of farmland, fruit trees, plantations and savannas.

Over thousands of years, the Loess Plateau, which once had a large area of ​​forest, has lost a lot of forest area due to human activities. Coupled with climate changes, this land has become even more arid and cold.

You know, in ancient times, there were elephants and rhinoceroses in the Yellow River Basin. The word "Yu" in Yu Province means elephant.

The decline of the Yellow River Basin, especially the Guanzhong Plain, is actually related to the cooling of the global climate. During the Spring and Autumn Period and the Warring States Period, the Guanzhong Plain did not have the current temperate continental climate, but a subtropical climate. The temperature and humidity were similar to those of the Yangtze River Basin today. .

Why did the core area of ​​the Central Plains Dynasty begin to move from the Guanzhong Plain to the North China Plain after the Tang Dynasty?

On the one hand, it is because the Guanzhong Plain and Loess Plateau have been over-exploited, causing severe damage to vegetation and severe soil erosion.

On the other hand, it is because the global climate has begun to transition from the interglacial period to the glacial period, causing the subtropical latitudes to gradually migrate to lower latitudes.

Julie turned her eyes away from the scenery outside the window and checked some e-books on her notebook, which contained research reports on geological time.

In fact, scientists in the academic community also have different opinions on the issue of global warming.

After all, according to archaeological and geological research in ancient East Asia, the Yellow River Basin in the Spring and Autumn and Warring States Period had a subtropical climate, and the global temperature at that time must have been much higher than it is now.

At that time, humans were not extinct. It can be seen that global warming is not an absolute disadvantage. It is even a benefit to the North China Plain, the Guanzhong Plain, and the Siberian and Eastern European Plains at higher latitudes.

The northward movement of the subtropical zone means that the subarctic zone will also move northward. The southern region of Siberia may become a temperate climate more suitable for farming. Maozi will probably wake up with a smile.

Of course, sea level rise is indeed a huge threat, and everything has two sides.

The train slowly stopped in Xixia District of Yinchuan.

Due to the obstruction of Helan Mountain, the wind and sand in the Tengger Desert did not have a serious impact on Yinchuan.

After getting off the train with their suitcases, Julie and Vivian were unfamiliar with the place and could only find a hotel to stay.

Under the guidance of the map navigation, the two came to the Time Business Hotel located near the Xixia Brewery. The reason why they chose this hotel was because among the hotel rankings, the Time Business Hotel had the best overall ranking, and it also had the ability to accommodate foreigners. human capabilities.

Just when the two of them arrived at the Time Hotel with their suitcases in hand.

Huang Xiuyuan and his team, who visited Longxian Semiconductor Industrial Park and Qingyang Data Center, also came to Yinchuan. As their own hotel, Time Hotel naturally became his destination.

When the Time Hotel was planning and constructing, it designed a special confidential independent suite in advance, which is equipped in every Time Hotel and is specially prepared for special receptions.

Coming out of the hotel parking lot, Huang Xiuyuan and his group entered the hotel lobby at the same time as Julie and Vivian. Zhang Lei and a dozen security personnel immediately raised their vigilance when they saw two girls with foreign faces.

Julie and the other two, who didn't notice anything unusual, checked in at the hotel front desk.

After checking in, the energetic Julie took the helpless Vivian on a tour bus to the Helan Mountain Forest Park in Shizuishan Mountain, because she knew from the Internet that the coal seam spontaneous combustion control area in Helan Mountain was right next to the forest park.

Huang Xiuyuan also wants to go to Shizuishan City.

The tourist bus and the convoy headed towards Shizuishan City one after another.

Huang Xiuyuan, who was sitting in the minibus, rubbed his temples and closed his eyes to rest. Xiao Yingnan was sorting out the company's internal documents.

"By the way, Yingnan."

"Chairman, what's the matter?"

"Is there any report from the Qiongzhou branch?"

Xiao Yingnan rummaged around on his tablet for a moment, then raised his head and replied: "There are two reports, one is this year's Qiongzhou Fruit Research Report, and the other is the Qiongzhou Strait Undersea Tunnel Research Report."

After taking it and browsing it, Huang Xiuyuan pondered for a while and then said: "Let Baijie go there. After all, the tunnel in the Qiongzhou Strait is very important."

"Understood." Xiao Yingnan nodded.

A few hours later.

Huang Xiuyuan saw Liu Xin and others in Rujigou Coal Mine of Ningmei Coal Group. Liu Xin, who had been in the coal mine for several months, became very dark.

Although their faces were exhausted, Liu Xin, Gao Shan and others looked excited.

Next to a coal seam that had been excavated, Liu Xin introduced him: "Chairman, fortunately, we have fulfilled our mission. The technology for controlling spontaneous combustion in coal seams has been tested. All spontaneous combustion coal seams in this coal area have been extinguished."

Looking at the coal seam covered with dark green crystals, as if they had dug an emerald mine, Huang Xiuyuan put on his gloves, picked up a piece of coal wrapped in dark green crystals, and looked at it for a while.

Throwing down the ore, Huang Xiuyuan clapped his hands: "What are you going to do next?"

"..." Liu Xin was speechless for a moment.

This question really made him think about it, because the coal seam spontaneous combustion control technology has been completed, and there is no need to invest too much energy in research next.

The problem before Liu Xin was to choose a new scientific research project, preferably one related to coal.

Just when he was deep in thought.

There was a burst of noise in English not far away, and Huang Xiuyuan frowned: "Zhang Lei, come over and take a look."

"OK."

Zhang Lei, who ran over with two security guards, saw two white girls taking pictures in the mining area before they arrived. They were discovered by several miners. The miners, who did not understand English, started to quarrel with the two girls.

A security guard who knew English translated a few words. It turned out that the two foreign tourists wanted to see the situation of spontaneous coal combustion control in person.

After Zhang Lei took the camera, he deleted the photos about the mining area, and then warned the two of them: "You two, your behavior is very dangerous and you may be regarded as spies. As tourists, you should stay in tourist areas instead of coming here to be dangerous. mining area.”

Vivian, who was still frightened, pulled Julie who wanted to say something.

The two sides were in a stalemate for a while, and the police team near the scenic spot sent people to take the two away.
