"What time will the helicopter arrive? Although Hong Bin's state has been controlled, it is not easy to move. ”

Li Bai was holding his mobile phone, and he could already see the appearance of the unmanned reconnaissance plane clearly.

It was not a balanced drone composed of multiple propellers, but a fixed-wing aircraft, with a single spiral located in the rear half of the fuselage, which looked a bit like the American Imperialist P38 "Lightning" fighter during World War II, except that it did not have two engines.

It is precisely because it is a fixed-wing model, the flight time and flight speed can be more suitable for the complex terrain of the Helan Mountains, if it is replaced by a multi-propeller balanced UAV, it is estimated that you will have to return just after entering the mountain, and the endurance is quite limited, although the static stability is very good, you can capture a clear and stable image, but the impact resistance is very bad, a gust of wind blows, most of them have to turn their heads.

"The helicopter is connected and ready to take off. ”

Professor Zhu Chaoye had already made arrangements, and he was at the scene of the command and personally kept in touch with the rescue team.

"That's fine, but don't let people into the tunnels, it's too dangerous. ”

Just running this trip is enough to toss, Li Bai doesn't want to save it a second time, so he reminds Professor Zhu again.

If there is a guy who doesn't have long eyes, he can't live if he or she does his own sin, so let him or her die!

He didn't want to save it anymore anyway.

Li Bai was originally a person who was quite afraid of trouble, and if he met a troublesome guy, he would naturally stay away, and it would be too late to hide.

"No, definitely not, don't worry, the Public Security Bureau has sent people to block the mausoleum, two posts inside and outside, there are people 24 hours a day, and no one will be allowed to go in." ”

Zhu Chaoye patted his chest and assured that the trespassing of the two students on their own initiative had brought great pressure to the archaeological team.

After the autumn, the credits of these two little things are not thought of here by his professors, and the lightest ones are expelled from the archaeological team, and those who are admitted to graduate school in the future are all rolling calves, and they are already adults, and they must be responsible for their actions and pay the price for their mistakes.

It is said that archaeology and tomb robbery are the same thing, one is a licensed operation, and the other is an unlicensed operation, but the two are essentially different.

Tomb robbery is the desperate opening or even destruction of the tomb, taking out the contents for money, during which the cultural relics and tombs will be damaged due to various incorrect operations, resulting in irreparable losses.

Archaeological teams generally do not move graves and monuments lightly unless they discover a cave or confirm that the artifact has lost its original preservation environment and has to carry out rescue excavations, the basic principle is protection, not monetary gain.

This tomb of the Western Xia Dynasty had to be excavated because of the discovery of the robbery hole, but the mysterious tunnel that extended out was not discovered by the tomb robbers.

Although two reckless students trespassed, the archaeological team did not investigate the tunnel, and in principle, it was still mainly closed and protected, and no matter what was inside, it would not act rashly.

"Okay! When the helicopter comes, remind us to release the smoke bombs. ”

After exchanging a few words with Professor Zhu Chaoye, Li Bai hung up the call.

The rescue team carried enough power storage equipment, and the power supply was still sufficient, not to mention the solar panels that were working, which could provide some additional power supply than nothing.

The fixed-wing unmanned reconnaissance plane flew around the location of the rescue group several times, and also projected a slender red laser beam, sweeping the platform and the mouth of the cave several times before turning around and returning home.

Two hours later, Professor Zhu's call reached Li Bai's mobile phone again.

"Doctor Li, can you find a wider place there, the pilot said that the field in front of the cave entrance is not easy to land. ”

Flight operations must be carried out with extreme care, because a crooked control stick may be blown by a sudden strong wind, and a major accident will occur in which the plane is destroyed and people are killed.

Although the platform outside the cave is not small, it is long and narrow in shape, with a steep mountain wall on one side of the cave entrance and an almost vertical cliff below the platform.

The helicopter that was about to fly over felt quite difficult, because when landing, it should not be too close to the direction of the cave entrance, and if you are not careful, it will hit the mountain, and the consequences will naturally be fatal.

In a complex environment like a mountainous area, it is desirable to have a wide enough field for a safe landing of the helicopter.

"It's not easy to do! It's steep terrain everywhere. ”

Li Bai stood on the platform in front of the cave entrance, looking left and right, looking embarrassed.

In a way, the position he was in was the equivalent of a Jedi, difficult for others to approach, and difficult for the rescue team to move to other places.

"Can you send people to this position a hundred meters above the entrance of the cave, I'll send the photos later." ”

When Professor Zhu made this call, he naturally had a backup plan, and he happened to take it out at this time to ask Li Bai's opinion.

"Wait, I'll take a look. ”

Li Bai soon received the pictures sent by Professor Zhu through WeChat.

Above is an aerial view, which should have been taken by the previous unmanned reconnaissance aircraft, with red circles marking the location of the hole and the platform, the suitable location for the helicopter to land, and the suggested walking route marked with red lines.

It may seem simple to put pen to paper on a map, but in practice, it is not the same thing at all.

If you follow the route plan drawn above, find the steep "path" that has never existed at all from the edge of the platform, and walk more than 100 meters diagonally upwards to reach the more spacious and open ridge, but it is almost a vertical climbing route, not to mention bringing a large living person with limited mobility, at least 145 catties, this is simply an impossible task.

Even if you don't bring people, climbing with your bare hands is not a simple task, and the danger is quite high, and if you are not careful, you will roll off the cliff and fall into mud.

Although this plan is very unsatisfactory, it is already a proposal made by helicopter pilots at great risk.

In addition, the only way to return is to follow the original path and retake the tunnel, although there is no need to climb the cliff, but no one dares to guarantee that there will be anything strange on the way back.

The rescue team and the rescued male and female students were actually in a dilemma.

Li Bai looked at the overlook map for a while, and then said, "I can take Hong Bin up, can the helicopter take everyone away?"

He didn't show the picture to the rest of the rescue team, because the problem would eventually turn back to himself, and no one else would be able to solve it.

Rather than let others risk rolling down the cliff and falling into the flesh, it is better to solve it with your own hands, and everyone will be happy.

After all, the professors invited Li Bai all the way over, in order to solve this trouble perfectly and return as safely as possible, instead of risking his life in the end.

"It's no problem to bring two or three people. ”

Answering Li Bai's voice changed, it was not Professor Zhu, maybe it was a helicopter pilot.

The helicopter invited by the archaeological team was not a large transport helicopter, but only a medium-sized helicopter with a rated capacity of only four people, including the pilot.

In other words, there are only three empty seats, and if there is any additional weight, it will have to be reduced again.

The aircraft could barely land on that ridge, and if it were to make a bigger circle, I am afraid that the place would be quite risky.

After all, the high-speed rotating propeller has a lot of scruples, and anything that is touched by it is fatal for a helicopter, and this coaster is not so easy to fly.

"Then send a batch away first, and then make a few more trips. ”

Li Bai estimated that he would have to run at least four times to get everyone out of this place.

Professor Zhu Chaoye said with some trepidation: "Doctor Li, is there really no problem with you over there?"

He obviously also knew the risks of this route plan, after all, it was hastily designed for the sake of time, and it had not been rigorously and carefully demonstrated, in fact, time could not afford to wait at all, and no one could guarantee that the condition of the wounded would not deteriorate, after all, if there was no comprehensive treatment for a long time, there was a high probability of accidents.

"No problem, I'll lead someone up the ladder. ”

Li Bai immediately made a guarantee, it is impossible to take everyone up at once, two or three are enough, in fact, there are too many people, and the ridge with a slightly flatter terrain will also be dangerous because of the air currents set off by the helicopter when it takes off and lands.

So to be on the safe side, it's safest to bring only one at a time.
