readx; This vast wasteland is a bit like the dead and silent open land that I once walked through shortly after entering the Tiankeng world, but most of the rocks in this wasteland emit a faint fluorescence, less darkness and more light......

The road under their feet was not difficult, and there were no dangers, so everyone moved much faster. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

However, walking in this rocky wasteland, it seems to return to the scene when I first entered the sinkhole, plain, unremarkable, no glowing trees, no sparkling insects, no strange ancient creatures, everyone always felt a sense of being in a different world, as if that fantastic place had only appeared in a dream.

After two short breaks on the way, in the evening of the outer world, as far as the eye could see, a towering mountain faintly appeared in front of me.

Ning Xiaofan took out his tablet, and the red main line displayed on the screen was only a short section, and the direction pointed at the end of the main line was the faintly visible mountain.

There is the destination called the grotto, and it is finally going to come out, Ning Xiaofan told everyone the news with a happy face, and when the fat man and the others heard it, they couldn't help but rejoice and cheered.

The so-called Wangshan ran a dead horse, the distance of that mountain was really not close, and Ning Xiaofan and his party traveled for nearly two hours before they could roughly see the true face of that mountain.

It is said to be a big mountain, but the shape of the mountain is quite strange, the top of the mountain is relatively flat, narrow at the top and wide at the bottom, there are no steep peaks, and there is no continuous mountain connection, like a huge rock, just like a reading power stands at the end of the wasteland, looking at it, like a huge diamond-shaped volcano, and like an artificially cast cube.

When they got closer, they also found that on the top of this huge cube, there was a tall signal transmission tower, as well as several huge white radar pot lids, and there were caves of different sizes on the walls of the cube, which resembled beehives, and what was even more bizarre was that the cube also emitted colorful fluorescence, giving people a gorgeous feeling.

Seeing the artificial traces on the top, everyone couldn't help but let out a long breath in their hearts, and their eyes were full of joy, the grotto had arrived.

"Welcome to Base 4 - Grotto."

Suddenly, a clear baritone voice came into everyone's ears, and this sudden voice startled everyone.

Where did this sound come from?

Just as everyone looked at each other, several searchlights flashed from the bottom of the cube in front of them, and the lampposts of the searchlights shrouded everyone's bodies, dazzling people.

And at this moment, only to hear a rumbling sound, at the bottom of the cube, blooming again, the light was a line, then extended to both sides, the light gradually widened, everyone looked at it, only to find that a huge iron door slowly opened.

As the huge iron door opened, through the light, several figures could be faintly seen appearing.

The sight in front of me is so sci-fi and shocking.

At this time, although everyone knew that this place called the grotto was the final gathering place of the various prospecting teams, they were still excited when those figures appeared, but when they met Label's group of unfriendly humans on the road, everyone was inevitably a little uneasy and a little nervous.

Among the people, Ning Xiaofan was quite calm, and among the top-secret information given by Aunt Xiang, there was a detailed description of the grotto.

This place, called the Grotto, began to be secretly built a few years ago, and is the last base to enter the Tiankeng world, which can also be called Base No. 4.

The grotto is also the last gathering place, transit station, and material supply place for all prospecting teams.

Ning Xiaofan also knows that in addition to the above functions, this grotto is also a scientific research institute, and has a navigation function, and the map displayed in the tablet can be accurately located, that is, the transmission tower at the top has been playing a role. Otherwise, it is estimated that Ning Xiaofan and his entourage will not know what year or month they will be able to find this place.

Ning Xiaofan was able to stay calm because he knew in his heart that the grotto, as the No. 4 base, could maintain video communication with the ground through the transmission tower, that is, the grotto was under the monitoring of the ground, so it could ensure absolute safety.

Out of the huge iron gate were five men and one woman, and at the front were a man and a woman wearing a field suit and a work badge on their chests, both of whom were over middle age, about 40 or so. He was followed by four armed men wearing headsets and holding Type 95s.

The five men and one woman approached, and one of them, a middle-aged man in a field suit, said with a smile on his face: "Welcome, welcome, welcome to the grotto, may I ask who is your team leader?" Please also come out and speak. ”

"I'm the team leader." Ning Xiaofan took a step forward and said.

"Hello, hello, my surname is Tang, Tang Yaoqiang, the first supervisor of the grotto base......" The man who claimed to be Zhang Yaoqiang stepped forward and took the initiative to shake Ning Xiaofan's hand, and then introduced the middle-aged woman next to him: "This is Zhang Jiayi, the second director of the grotto base, welcome to you." ”

"Hello, my name is Ning Xiaofan, the captain of the advance prospecting team." Ning Xiaofan also introduced himself.

"It turns out that you are Captain Ning Xiaofanning, you have worked hard, in the past few days, my ears are almost calloused when I hear your name......"

Ning Xiaofan listened to the meaning of his words, as if he knew that there was such a person as himself, and was slightly stunned: "Have you heard of me?" ”

"But no, speaking of which, you and I both belong to the Xinao Group, and we can be regarded as colleagues, and in the past few days, the above has to ask you about your situation from time to time......"

Someone above asked himself? It is estimated that it is not Aunt Xiang, or Sister Yulan, well, Yu's mother is the person in charge of the base, and she may also ask about herself.

In his mind, Ning Xiaofan glanced at the work card on his chest, which had the logo of Xinao Group on it, and smiled at the moment: "Let the people above worry, fortunately, it is finally to the ground." ”

Tang Yaoqiang said with emotion: "Yes, if you don't arrive again, I don't know how to reply to the above words, but fortunately, you finally arrived safely, hehe, your advance exploration team is the latest to arrive...

"Oh, Director Tang, there are other teams from the previous ones who have already arrived?"

"Yes, there have been several advance prospecting teams have arrived, but your team has not arrived, I am in a hurry, and I am thinking about whether to send a team to find you, look at you like this, there was an accident on the way, right?"

"It's an accident...... Ning Xiaofan replied vaguely, and didn't explain the reason, before leaving, he signed a confidentiality agreement, everything he saw on the road and everything he encountered must be kept confidential, and only after returning to the company can he form a written report and hand it over to his direct supervisor, that is, the little goblin.

Tang Yaoqiang seemed to know that there was such a thing, and he didn't care about Ning Xiaofan's vague response, and he didn't ask, he smiled: "It's good to arrive, I can imagine your hard work along the way, when you get here, you can rest in peace for a while." ”

Tang Yaoqiang said, turned his eyes to Professor Zhao and Li Wanting, and a trace of doubt crossed his eyes: "Captain Ning, the structure of your team is not quite right?" I remember that the number of advance teams is regulated, no more than seven, and the number of people in your team seems to be a few more. ”

The meaning of Tang Yaoqiang's words is more vague, but the meaning is very clear, Professor Zhao in the team is older, and there is a rather beautiful woman, who is obviously not a member of the advance prospecting team.

Ning Xiaofan hurriedly explained: "Director Tang, the extra people were met on the road, let me introduce you, these are members of the joint scientific expedition team of Xinao and Jiangnan University, let me introduce you, this is Professor Zhao, Professor Wu, Dr. Li Wanting, and this ...... Captain Yang Haiyang, the security guard of the expedition team......"

After listening to Ning Xiaofan's introduction, Tang Yaoqiang suddenly said: "It turned out to be a joint scientific expedition team, I know, I know, but ...... Why are there only these few people? What about others? I have a list there, the number of people is more than this, by the way, the team leader should be Wang Zhipeng of our company, why is he not there? ”

"This ...... It's a long story, and I'll report it back when I get back. Ning Xiaofan still replied vaguely

"That's it, I understand...... Tang Yaoqiang smiled meaningfully, and said: "Okay, let's not talk outside, according to the regulations, before entering the base, you have to show your documents, this is the rule, so please understand." ”

"It should." Ning Xiaofan smiled, took out the identity card, and then motioned to the fat man and the others to take out their documents.

The fat man and the others looked at them one by one, ragged and embarrassed, and the documents they carried with them were unconscious, so they took them out one after another to reveal their identities.

After checking his identity, Tang Yaoqiang made a gesture of invitation and walked towards the iron gate.

Entering the iron gate, the iron door slowly closes, the iron door is brightly lit, and what catches your eye is a spacious hall, however, the hall seems empty, without any facilities, but there are a few elevators directly opposite the hall that are simply fenced with iron railings. In front of each elevator, there are two armed guards.

When he arrived at one of the elevators, which looked rather simple, Tang Yaoqiang stopped, turned his head sideways and said to the woman named Zhang Jiayi: "Director Zhang, Captain Ning and his party will be handed over to you to settle down." ”

Zhang Jiayi nodded.

Then, Tang Yaoqiang looked at Professor Zhao, Li Wanting and the others: "Please come with me for the joint scientific expedition team, you have other arrangements." ”

As soon as Tang Yaoqiang said this, Ning Xiaofan and the others were stunned, Li Wanting was a little reluctant, and hurriedly said: "Director Tang, can't we be with Captain Ning and them?" ”

There are outsiders, Li Wanting still pays more attention, does not expose the relationship between the two, and directly calls Ning Xiaofan Captain Ning.
