After the rope was attached, several staff members checked it again to confirm that it was correct, and several of them put it on their climbing belts. Pen, fun, and www.biquge.info

One of them, a yellow-haired, blue-eyed, muscular foreigner, who seemed to be the leader of the group, said in native American English: "Minister, we will start going down the cave now, we will leave a professional man, and you can come down only after we have confirmed that the bottom of the cave is safe, I hope you can comply." ”

The planning minister nodded and replied in English: "No problem." ”

There are a total of five external professional search and rescue personnel, plus four professional wilderness rescue experts brought from China by the starting point TV, a total of nine experts, one of whom is left to test the equipment on it, and the remaining eight are all pulling ropes, carrying professional equipment backpacks, and entering from the hole in turn.

The entrance to the cave is not big, and if two people go down at the same time, it will seem a little crowded, but they go down one by one, which is a lot more relaxed.

There are special locking knots on the climbing belt that can be tightened at any time to slow down the fall.

At the head was the yellow-haired foreign search and rescue worker, who controlled the knot in one hand and slowly descended, holding a detector in the other, staring at the values above.

This is a professional gas detector, the purpose is to detect whether there is any toxic gas, like this very deep underground cave, generally the concentration of carbon monoxide is very high, mixed with air, forming a mixed gas, in case of open flame, it is easy to produce an explosion.

"How's it going, Jack?"

Above, other search and rescue personnel asked through the walkie-talkie.

"I haven't found any problems at the moment."

Jack replied to the intercom and continued to stare at the detector.

The height of eighty or ninety meters is very high for ordinary people, almost equivalent to a 30-story building, but for these professional search and rescue personnel, it seems nothing.

Hawaii is one of the world's most famous tourist attractions, and the safety of visitors is important, so the professionals are also excellent.

Ten minutes later, Jack had seen the ground through the illumination of the headlamp, "Thank God, great, there is a dark river underneath, it seems that there is a great possibility that they are still alive!" ”

All the personnel were on the same channel on the walkie-talkie, so on the ground, everyone also heard Jack's words through the walkie-talkie.

"Ahh That's great! ”

The planning minister shouted fiercely, "God bless, God bless!" ”

"Great, Brother Zhang Shan is not dead!" Zhao Shanshan's eyes were wet.

Yang Mi, Chen Qiaoan, Zhou Ke, Chen Chichi and others are all very excited, as long as there is water, not only can it be used as a buffer, but also a water source, maybe there is food in the water, and the two of them will have a good living environment.

He Jie was stunned, what, not dead?

Wang Sen was even more frightened, damn, how is it possible, there is a dark river down there?

What to do!

If Zhang Shan and Lin Yun'e are not dead, won't their murderous crimes be revealed?

As soon as he thought of this, Wang Sen was terrified, after all, he was going to prison!

Damn, I should have stabbed them to death in the first place!

……

"Jack, can we go down now?"

The planning minister can't wait to find Zhang Shan and Lin Yun'e, as long as he finds them, he can not only keep his position, but also keep the show, as long as he keeps this show, it will be a great achievement!

After all, Wild Food is just too hot right now!

"Wait a minute."

Jack's voice came over the intercom, "No, why is the oxygen content in this underground so high, it has exceeded the proportion of oxygen in the land air, and it has reached more than 50%!" ”

"What's wrong?"

The planning minister frowned, worried, but don't make any more moths!

"It's nothing, unless it's a high-oxygen environment with a concentration of more than 70 percent, humans will be poisoned, and this concentration is not a big problem at present."

Jack explained, "Alright, you can come down!" ”

The crowd breathed a sigh of relief, so they put on their climbing belts, fastened the buckles to the climbing ropes, and made holes.

As the starting point TV staff went down the hole with the guests, the drone also slowly fell from the hole and followed the shooting.

And just a short time after everyone came down, a scream suddenly came from the walkie-talkie:

"Oh my God! What is this! ”

"Monsters!"

"Don't panic! He seemed to be dead, and you see, there was an arrow above his head! ”

……

The staff and guests of the starting point TV looked confused, "Jack, what's next?" ”

"It's okay, it looks like a giant salamander-like creature that has been shot dead on the shore." After a few moments, Jack said.

Giant salamanders?

How big is it? Could it be that there are monsters underground?

With doubts, everyone continued to go down the cave.

Finally, when they went down to the dark river, everyone swam to the shore and saw that there was a huge black creature on the shore, which looked like a gecko and a lizard, but it was smooth and disgusting.

"Damn, such a big salamander has never been seen before!"

"Aren't axolotls a few centimeters in size, how can they be so big?"

"I'm afraid it's more than three meters long, and it must be able to eat people!"

"It's scary, what the hell is this desert island!"

……

Yang Mi looked at the huge salamander corpse, "It's terrifying! ”

"yes, something, how can it grow so big!" Chen Chichi was also afraid.

Jack glanced at the monster, then at the detector in his hand, thought for a while, and suddenly realized: "I know, this salamander should be the ancient overlord salamander species, in ancient times two or three hundred million years ago, the earth was still in the Carboniferous period, and the Carboniferous period is also known as the 'age of giant insects', because the atmosphere was very oxygen-rich at that time, and the climate was warm and humid, so the insects grew very large." ”

"Look here, it is located in a tropical climate, along the coast, the climate is warm and humid, and this underground, for some reason, has an oxygen content of more than 50 percent, which is fully equipped with the growth environment of giant animals and insects!"

After some explanation, everyone understood.

Jack looked at the corpse of the overlord salamander, "It's a pity, if it's a living overlord salamander, this is simply a miracle of the world, a Carboniferous creature, a living fossil from 300 million years ago!" ”

The planning minister looked at the arrow on the head of the overlord salamander, "This should have been killed by Zhang Shan, the arrow is a carbon arrow equipped by our program team, I remember!" ”

"It's amazing."

Another American search and rescue worker exclaimed, "Such a big salamander, with hundreds of kilograms of explosive power, was not only cut off from its tongue, but also killed by an arrow, this Zhang Shan is really a master!" ”
