the next day.

After getting up, Julie and Weiweian visited various tourist attractions near Chang'an under the leadership of Zhang Lei and Hall.

After traveling in Chang'an for a few days, Julie did not keep running towards tourist attractions during these days, but also took the time to go to ordinary residential areas and streets and alleys, and took a deep walk.

She found that the Eastern world she saw with her own eyes was actually a world of difference from the Eastern world mentioned by Western media in the past.

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

August 2.

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

Julie and Vivian said goodbye to Zhang Lei and Hall. The two took the train to Ning District by themselves. 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 beside the train window, Julie looked at the view on one side, and changed little by little as the train advanced.

Unlike the southern part of Qin Province, which is densely populated by scenic spots and historical sites, the northward area is full of gullies on the loess high slopes, and the types of vegetation have also changed significantly.

Unlike the Qinling Mountains near Chang'an, where there are dense forests and vegetation on loess high slopes, it is a mixture of farmland, fruit forests, artificial forests and sparse grasslands.

For thousands of years, the loess high slopes with large areas of forests have been greatly reduced due to human activities. Coupled with the changes in climate, the land is even more drought and cold.

You should know that in ancient times, there were elephants and rhinos in the Yellow River Basin, and Yu in Henan Province means elephants.

The decline of the Yellow River Basin, especially the Guanzhong Plain, is actually related to the global climate cooling. During the Spring and Autumn Period and the Warring States Period, the Guanzhong Plain at that time was not the current temperate continental climate, but the subtropical climate, with temperature and humidity similar to that of the current Yangtze River Basin.

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

On the one hand, the Guanzhong Plain and the Loess Plateau were overdeveloped, and vegetation was severely damaged, resulting in severe soil erosion.

On the other hand, it is because the global climate has begun to transition from the interglacial period to the ice period, resulting in the gradual migration of the subtropical latitude to the low latitude.

Julie turned her eyes away from the view outside the window, and looked at some e-books on it, which contained research reports on geological age.

What is the problem of global warming? In fact, scientists in the academic community have different opinions.

After all, according to archaeological research and geological research in ancient East Asia, in the Yellow River Basin during the Spring and Autumn Period and the Warring States Period, the subtropical climate was the temperature around the world at that time, and the temperature in the world was definitely much higher than that now.

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

The subtropical migration northward means that the subrotum will also move northward. The southern part of Siberia may become a temperate climate that is more suitable for farming, and the Russians will probably wake up with a smile.

Of course, rising sea levels is indeed a huge threat, and everything has two sides.

The train slowly stops in the Xixia District of Yinchuan.

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

Pulling off the train with his suitcase, Julie and Vivian were not familiar with each other, so they could only find a hotel to stay.

Under the guidance of map navigation, the two came to the Time Business Hotel near Xixia Brewery. The reason they chose this hotel was because among the hotel rankings, Time Business Hotel has the best comprehensive ranking and has the ability to receive foreigners.

Just as the two of them pulled their suitcases and arrived at the Time Hotel.

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

When planning and construction, Time Hotel designed a dedicated confidential independent suite in advance, which is provided by Time Hotel and is specially prepared for special receptions.

After leaving the hotel parking lot, Huang Xiuyuan and his group, Julie and Vivian stepped into the hotel lobby at the same time. Zhang Lei and more than a dozen security personnel immediately became alert when they saw two girls with foreign faces.

Julie and the other two checked in at the hotel front desk.

After checking in, Julie, who was energetic, pulled Vivian with a helpless look on her face and took a tourist bus to Helan Mountain Forest Park in Shizui Mountain, because she learned from the Internet that the coal seam spontaneous combustion control area of ​​Helan Mountain is next to the forest park.

Huang Xiuyuan also wants to go to Shizuishan City.

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

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

"By the way, British man."

"Chairman, what's the matter?"

"Is there any report from Qiongzhou branch?"

Xiao Yingnan searched on the tablet for a moment, raised her head and said, "There are two reports, one is the research report on Qiongzhou fruit this year, and the other is the research report on Qiongzhou Strait Undersea Tunnel."

After taking it, Huang Xiuyuan pondered for a while before speaking, he ordered: "Let Baijie go there, after all, the tunnel in the Qiongzhou Strait is very important."

"I understand." Xiao Yingnan nodded.

A few hours later.

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

Although his face was exhausted, Liu Xin, Gao Shan and others looked excited.

Next to a piece of coal seam that has been dug, Liu Xin introduced to him: "Fortunately, the chairman has fulfilled his wish. The coal seam spontaneous combustion treatment technology has been tested, and all the 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, wearing gloves, picked up a piece of coal wrapped in dark green crystals, and watched 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 treatment technology has been completed, so there is no need to invest too much energy in research.

The question facing Liu Xin is to choose a new scientific research project, which is better to have something to do with coal.

Just as he fell into deep thought.

A noise in English came from a distance, and Huang Xiuyuan frowned: "Zhang Lei, go and take a look."

"OK."

Zhang Lei, who ran over with two security guards, saw two white girls taking photos in the mining area before he could even arrive. Several miners found out that the miner who did not know English started to quarrel with the two girls.

A security guard who knows English translated a few sentences and found that two foreign tourists hoped to see the situation of the coal seam spontaneous combustion control on the spot.

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

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

The two sides were in a stalemate for a moment, and the police force near the scenic area sent someone to take the two away.
Chapter completed!
