The regulations in Base No. 1 are much stricter than those in Base No. 1. Ever since Ning Xiaofan and his party moved into the living area, their scope of activities has been basically limited to this area. Fortunately, the living area is large enough and various facilities are relatively complete. Apart from a lack of freedom, there is nothing uncomfortable about it. What¡¯s more, Ning Xiaofan¡¯s hands were injured and he was not suitable for strenuous exercise. He most often took a walk near his residence. The rest of the time, he either watched TV to kill time or opened his laptop to play P. Two days passed in a flash, and many teams arrived one after another, and this quiet living area became more and more lively. In the past two days, Ning Xiaofan has not seen the little goblin in person, but he did hear that the little goblin was sent to the medical clinic for examination, and the remaining poison in his body was not cleared, and he was still receiving treatment at the medical clinic. Although Ning Xiaofan didn't like the little goblin very much, he was still a little worried about her. Later, he heard that her treatment effect was good and she only needed to rest for a few days to recover, so he felt relieved At noon that day, Aunt Xiang received a phone call and hurried out without even having lunch, and did not return to her residence until evening. When Aunt Xiang came back, she looked a little tired. After taking a bath, she rested early. However, before she returned to her room, she gave Ning Xiaofan a disk and said it was information about the tiankeng, and asked him to check it out on his own. Since Ning Xiaofan witnessed the giant tiankeng on the top of Huangtou Ridge, he has always been in awe and curious about the giant tiankeng. He also asked Aunt Xiang about the giant sinkhole, but Aunt Xiang seemed to have some concerns and always talked to him. Aunt Xiang seemed to have something to hide. Although Ning Xiaofan was puzzled, she was not so ignorant, so she buried her doubts deep in her heart and stopped asking further questions. Now, Aunt Xiang has explained that this disk contains information about the giant sinkhole. When Ning Xiaofan returned to the bedroom, he couldn't wait to open his laptop and put the disk into the drive disk. Clicking on the disk file, a password box pops up first. Ning Xiaofan enters the password according to Aunt Xiang's instructions. With a slight click, a new page pops up. Then, two big words appeared on the page - Top Secret. Seeing these two big words, Ning Xiaofan's expression became cautious involuntarily. I clicked on the next page, which showed rows of text. I glanced at it for a few times. It was about confidentiality regulations. Ning Xiaofan once served as a soldier and was engaged in the dangerous blasting industry. He was no stranger to confidentiality regulations. However, when he saw the punishment for violating confidentiality regulations, he couldn't help but froze. According to the general confidentiality regulations, there are only a few punishments for leaking secrets, either dismissal or fines, or more seriously, legal sanctions at most. But the punishment for leaking secrets in front of us is a bit shocking. It¡¯s just four words, the leaker will die? Ning Xiaofan felt a little unbelievable. We are now a legal society. Even if you commit a capital crime, you still have to pass the test of the public prosecutor. In other words, even if Xinao Group is a behemoth with tens of billions of dollars in assets, it does not have the right to deprive others of their lives at will. Right? With full of questions, Ning Xiaofan clicked on the next page. There is a picture on the page. The image is easy to recognize. It is a sinkhole. However, the sinkhole shown in the image is not large, with a diameter of less than 100 meters. In this regard, judging from the proportion of several people standing next to the sinkhole, It can be seen. Shennongjia Tiankeng. When Ning Xiaofan saw the words in the annotation under the picture, he was startled at first. He was still thinking in his mind that the tiankeng in this picture and the giant tiankeng here are completely different things. They are probably tiankeng elsewhere in Shennongjia. Then turn the page, and the page still displays a picture. The picture is still a tiankeng pattern. There are still people standing next to the tiankeng, but judging from the ratio of people to the tiankeng, the area of ????the tiankeng in this picture is much larger. . Of course, compared with the giant sinkhole, it still pales into insignificance. The text in the picture annotation is still Shennongjia Tiankeng, but there is an additional data of the diameter of the tiankeng, which says 5 meters. Then click on the next page, which is still a picture of a tiankeng. The area of ????the tiankeng seems to be much larger than the previous picture. The diameter of the sinkhole in the picture is 513 meters. Seeing these three pictures of the ever-expanding tiankeng, Ning Xiaofan had a vague guess in his mind, but he was not sure yet, so he clicked on the page a few times. Without exception, the pages that are opened in succession are all pictures of tiankeng, and the data of the diameter of the tiankeng continues to grow as the page is turned down. After clicking all the way to the last page of the picture, Ning Xiaofan saw a very familiar picture - a giant tiankeng. Not only that, this picture seemed to have been taken on the top of Huangtou Ridge, almost from the same perspective as Ning Xiaofan. Same location. Is the small tiankeng shown in the first picture the giant tiankeng today? Ning Xiaofan was a little surprised. How big is the small tiankeng, with a diameter of more than 100 meters? How big is the giant tiankeng? Just by visual inspection, the diameter is probably several miles, right? Could it be that this sinkhole will grow on its own? How can it be? ? ?Xiaofan was not surprised for long. Soon, the dense text and data on the next page solved the mystery for him. The Shennongjia Tiankeng was discovered in 2019. It was a forest ranger and a local herb collector who discovered the sinkhole at that time. At that time, the two discoverers did not report the tiankeng to the organization. The discovery of the tiankeng was only circulated locally. In 19RU, after receiving the news, the Xiangbei Provincial Geological Bureau sent a small expedition team to conduct a preliminary inspection of the Shennongjia tiankeng. Due to insufficient equipment and other reasons, the expedition team only measured the diameter of the tiankeng and did not reach the tiankeng. bottom. Exactly 10 years later, in 1990, a scientific expedition team to investigate the savages came to the Shennongjia Tiankeng again, and with the help of equipment, reached the bottom of the Tiankeng. They further investigated the geology and formation of the Tiankeng, and found that there were A cave was found at the bottom of the pit. Due to lack of time, logistics, and equipment, the expedition team only went a hundred meters deep into the cave before stopping. At the end of this investigation, all the information on the investigation of the Shennongjia Tiankeng was submitted to the State Geological Bureau and the Institute of Biology, and attracted media attention. Five years later, in 1995, with the sponsorship of Xinao Group, the National Geological Bureau, Beijing University, Nature Research Association, Xiangbei Provincial Tourism Bureau, and Xinao Group formed a joint scientific expedition team to enter Shennongjia again and conduct a survey of the sky. The pit conducted a relatively extensive scientific research. This joint expedition team once penetrated about one thousand meters into the cave at the bottom of the pit and discovered a large number of stalactites in the cave. They also discovered the existence of underground rivers in the cave, as well as some unknown insects, microorganisms, plants, etc., and brought back a large number of ore for further study. Based on this inspection, the joint inspection team came to a preliminary conclusion that the Shennongjia tiankeng is similar to karst landforms and was formed at least 100 million years ago From 1999 to 2001, the Xinao Group and the National Geological Bureau worked together for more than two years. During this period, 13 inspections of the Shennongjia Tiankeng were conducted. As of July 2001, the sinkhole collapsed for the first time, and the scientific expedition was forced to stop. From 2001 to 2007, the tiankeng collapsed at least three times a year, and its area grew rapidly. It was not until April 2007 that the tiankeng stopped collapsing, forming a giant tiankeng with a diameter of 3 miles. After the collapse of the Shennongjia Tiankeng stabilized, the Xinao Group invested huge amounts of money in the name of scientific research and tourism development and reached a joint development agreement with the State Geological Bureau, the National Tourism Administration, and the Nature Research Association. After completing all the legal procedures of the Bureau of Land and Resources, the State Environmental Protection Administration, and the National Security Administration, we obtained the rights to long-term inspection of the Shennongjia tiankeng, tourism development, and some mineral development. In March of UR, Xin'ao Group broke ground one after another outside Shennongjia and near the tiankeng, and began to build a scientific research base, which has continued until now The giant tiankeng actually evolved from the collapse of just a few years. Come. As for why the sinkhole collapsed? There is no further description in the data. The next page is about the base construction and the internal construction of the tiankeng. It also appends a lot of pictures of the inside of the tiankeng, so that Ning Xiaofan has a certain understanding of some conditions inside the tiankeng. About the inside of the tiankeng There were not many pictures and descriptions in the information, but Ning Xiaofan was pleasantly surprised to see records about gems from the later information. In this information, the gems that Ning Xiaofan had been thinking about had an official name. It was the same as the one that Fatty had learned from Feng Zijun, the man in Tang suit. They were collectively called Tianling Stone and Earth Spirit Stone, and Earth Spirit Stone was classified according to the era. They are Jurassic Stone, Chalk Stone, New Origin Stone, etc. However, whether it is a Heavenly Spirit Stone, an Earth Spirit Stone, a New Origin Stone, etc., this information only uses the official name at the beginning, and then continues. The written descriptions below are all replaced by the names of gems The information about gems is relatively detailed. It took Ning Xiaofan more than an hour to read it all. Compared with the information he got from Koreans, it is much more detailed. times. In addition to text descriptions, there are also many pictures. Browsing them is an eye-opener for Ning Xiaofan. After reading the gem chapter, Ning Xiaofan thought this was the end of the information. He never wanted to read it casually. There was still dense text below. Ning Xiaofan lit a cigarette and then browsed down. This time, what he saw was not a surprise, but something that frightened him. The further he looked down, the more solemn Ning Xiaofan's expression became. He forgot to smoke the cigarette in his hand, so much so that the cigarette burned his fingers, which was when he woke up in shock. After reading the information, Ning Xiaofan let out a long breath, lay down on the chair, and found that his back was covered in cold sweat. At this moment, he finally understood why the word "top secret" was included in the beginning of this information, and why the penalty for leaking secrets would be the price of life. People die for money, and birds die for food. Ning Xiaofan thought of this sentence from his ancestors and summarized it. A bitter smile appeared on his lips. Things had gone beyond his imagination. This prospecting trip would be more terrifying than he imagined.?Dangerous
