After Gu Fengchun got off the plane, he always felt that there was a faint fragrance in the air, if there was nothing. I sniffed it carefully, but I couldn't feel it. I was puzzled in my heart, and when I heard Zhou Dingxuan reading Cao Yunfei's diary, my heart sank, and I said secretly: "Is this the taste?" After listening to Chen Si and Ye Ya's analysis and questions again, he lowered his head and did not speak.

Liu Wensheng set up his compass house, wore his reading glasses, walked around and stopped, and kept muttering something in his mouth. He had little interest in the conversations of these people, nor was it within his scope of work, nor did he want to care. It's just that it's getting late at this time, and the visibility is low, so he can't stop shaking his head.

At the moment, W Bureau.

Xie Haidong put down his phone and sighed faintly. All the personnel have arrived at their destination, and immediately launched a search and rescue, and Ye Ya gave him a brief report on the phone.

"What are you sighing about?" An old and serious old man was sitting in his comfortable chair, holding Erlang's legs, looking at him coldly. The old man has silver hair, a slightly bulging bone between his eyebrows, a pair of red phoenix eyes, a very high nose, and a height of more than 1.8 meters.

"Nothing." Xie Haidong looked at the old man's eyes as sharp as a goshawk, and a chill broke out in his heart. "It's a pity that Cao Yunfei them." Xie Haidong said.

"Hmph, they deserve it! I was about to dig when the moon was full, and I alarmed the phantom inside, didn't I warn you! The old man slapped the table fiercely, "If it weren't for my people who got in the middle of it, activated the blood ransom, and suppressed the herd of animals, otherwise the consequences would be even more unimaginable." ”

"Yes, it's really thanks to you this time." Xie Haidong sighed, and then asked, "Next, what should we do?" ”

"As long as Zhou Dingxuan and Liu Wensheng have no accidents, and the metal pipe does not fall into the hands of the people from the military, they will definitely be able to enter the hidden city, and I have arranged the rest of the matter. The elixir of immortality belongs to you, and I only need the reincarnation seal. The old man touched the jade wrench on his thumb and said.

Xie Haidong took a deep breath, then nodded, and asked hesitantly, "What about "Returning to Tibet"? Isn't the elixir of immortality tempting you? Xie Haidong looked at the wrinkles on the old man's face and said softly.

The old man smiled "haha" and said, "Returning to Tibet"? I'm very interested in this, but it's useless to me now, and if you have the chance, you'll understand in the future, what exactly is "Returning to Tibet". As for the elixir of immortality and the seal of reincarnation, I would rather choose the path of reincarnation than contact the elixir of immortality, one day, you will find out how painful it is when the length of life will make you tired but unable to end. At this, the old man lowered his head, as if thinking about something.

Xie Haidong smiled bitterly at the old man, who would say a few philosophical words to him from time to time, making him unable to figure out what the old man's mind was.

"It's 19 o'clock in the afternoon, and we immediately start searching." Ye Ya didn't care that the night was dark, and gave an order to the search and rescue team. He had already discussed with Chen Si, and each team entered the cave and carried out search and rescue in separate ways, while the rest of the personnel searched in the mountains and forests outside.

Chen Si had already expressed no objection to his approach, and also took the initiative to bring the people he led to facilitate the management and transfer. Of course, Ye Ya agreed with this proposal. The two immediately divided their labor, and the team led by Ye Ya explored the newly discovered secret passage of the archaeological team, while Chen Si continued to go deep into the unknown area on the karst cave.

After entering the cave, Gu Fengchun always felt uncomfortable in his heart. The dark underground world, with its bizarre stalactites and stalagmite canine teeth, is colorful and looks bizarre under the illumination of the light. Looking at these scenes, Gu Fengchun felt like a huge monster in front of him opening its big mouth full of fangs, waiting for them to send the sheep into the tiger's mouth.

"Ye Ya, I don't know why, I always feel hung in my heart, and I seem to be very uneasy in my heart." Less than two minutes after entering the cave, Gu Fengchun couldn't help but say to Ye Ya: "I feel that there is a very huge danger in front of us. ”

Ye Ya smiled and said, "This is a normal psychological phenomenon, don't be nervous." Ye Ya patted the backpack on his back vigorously and said, "The weapons and utensils here are enough to deal with possible dangers." ”

Gu Fengchun frowned and said, "Don't be careless." You know better than I do, a whole A-guard detachment of more than forty people in the third archaeological team has disappeared without a trace, you have neither three heads and six arms, nor are you a Transformer, how many dangers can you handle? Gu Fengchun retorted to him.

Ye Ya nodded, put away his smile and said, "You are not bad at all, don't worry, I won't let anything happen to you!" Ye Ya said this, and patted Gu Fengchun's shoulder heavily. When Gu Fengchun heard this, a trace of warmth flashed in his heart, and he said secretly: "I won't let you have an accident." ”

In Ye Ya's team, there are thirteen A guards, including Ye Ya, plus Zhou Dingxuan, Gu Fengchun and Liu Wensheng, a total of sixteen people. As soon as Liu Wensheng entered the cave, he looked around in a ghostly manner, but the panic on his face could not be stopped in his eyes. Zhou Dingxuan was calm, he had been accustomed to this place for half a year.

There are many forks in the cave, the deeper you go, the more strange the stalactites on the top of the cave, the more bizarre and bizarre; The dazzling array of colors is a sight to behold, and this bizarre landscape takes a long time to form. However, for unknown reasons, the cave has become very dry, and the stalactites have stopped growing.

It is important to know that the formation of stone stalactites is that when calcium carbonate encounters water dissolved in carbon dioxide, it will react to form calcium bicarbonate with greater solubility; When the water dissolved with calcium bicarbonate is heated or when the pressure suddenly becomes small, the calcium bicarbonate dissolved in the water will decompose, regenerate calcium carbonate and deposit it, and release carbon dioxide at the same time, when the water at the top of the cave slowly leaks downward, the calcium bicarbonate in the water undergoes the above reaction, some are deposited on the top of the cave, some are deposited at the bottom of the cave, the formation of stone stalactites on the top of the cave over time, and the formation of stalagmites at the bottom of the cave. It is also because of this that there should be a large amount of carbon dioxide in the cave, so as soon as you enter the cave, everyone is asked to pay attention to prevent carbon dioxide suffocation and poisoning. Fortunately, the archaeologists have been using exhaust fans to bring fresh air to the inside, which is not too stuffy.

The further you go inside, the more open the space becomes; The whole cave is inclined to the inside, and the strong lighting illuminates it, and it is soon blocked by the curved karst cave, diffusing around, and those stone stalactites shimmer with ever-changing colors, which is beautiful. But at this time, no one spoke, and there was no other sound except for the echoing footsteps.

Ye Ya took out the map surveyed and mapped by the archaeological team, and said to Gu Fengchun: "The map surveyed and mapped by the archaeological team has a known area of about 4 square kilometers, and the unknown area of this underground cave may be larger, and the food and water carried by everyone is enough for three days, but you know, if the missing people here are really inside and still alive, they may not be able to support it for so long, the air here is thin, there must be many other dangers inside, we must be mentally prepared for the worst." ”

Gu Fengchun nodded. He had thought of this question for a long time, but he never said it. But he wasn't quite sure in his heart, whether the missing person was really inside?

The more Zhou Dingxuan walked inside, the heavier his mood became. The truth about the whereabouts of the archaeological team is clear to him only at the moment. It's just that he can't tell Ye Ya and the others. If so, it will definitely cause more accidents than the three archaeological teams have disappeared collectively.
