Guyu told the whole story of the strange situation he heard, and all the six people around him were stunned.

Because, they can't find the answer to any of these weird ones.

It is almost impossible to go down this cave without a rope unless it is a gecko.

It is simply unreasonable to get into an ice hole and bring ice cubes of iced drinks and red wine.

Of course, this is based on the brain of an explorer, and the answer cannot be found.

If it weren't for adventure lovers, like Julie, this question seemed to have an answer.

This girl thought about it and said:

"I don't think this is strange. Professor Jackson probably had an accident when he went down, causing the rope to fall off, and he fell to the ice cave at a relatively safe height and did not fall to death. This may be the reason why he couldn't get out.

He brought ice cubes specially designed for iced drinks and summer clothes because he didn't expect that ice caves would appear on such a terrain, so it's not difficult to explain that he brought ice cubes.

The last bubble ice cave may have an entrance and exit when Professor Jackson entered, but as the ice and snow melted, it might block the entrance and exit."

This is Julie's presumption of "mistake", that is, all puzzles are caused by the mistakes of Jackson, a professional explorer.

Sister Le shook her head and said:

"Professor Jackson doesn't know how to make these low-level mistakes, and absolutely won't. Not long after I just appeared in the black snake totem on the back of my neck, he once taught us. He is a very amazing explorer, very professional and has super high wisdom."

Julie whispered:

"But, what I said should be the only possible explanation."

Maoyan waved his hand and said:

"Let's study the real reason later. The most important thing we are to bring out Professor Jackson's body and personal belongings, and then hurry up and leave this island that is about to become a dead place."

Sister Le nodded and said:

"Beautiful, young man She, I'm going to work on the expansion bolt, Maoyan, Guyu, you two follow me."

Maoyan nodded in response.

He has a unique perception ability and can avoid many risks with him. Such an unknown map is naturally indispensable, and Maoyan had expected it.

Guyu licked her lips, but she really couldn't find a reason to refuse.

Without it, no one knows the specific location of Professor Jackson except himself, so he has to follow.

The three of them wore safety helmets, with ice axes on their waists, and crampons on their feet in advance, and began to slide downwards along the safety rope that was tied and explained.

Guyu has often trained in climbing ropes in the mountains before. Although he hasn't touched it for a few years, he is not afraid at all.

The cave is not vertical, and the deeper the space, the larger the space. There is a bend on the belly halfway. Fortunately, Gu Yu had already heard the outline inside, so when he tied the rope, they were all on the side of his belly and could touch the rock wall all the time, so that they would not have nowhere to leverage force.

More than 100 meters sounded like a long time, but it was really useless to climb down.

Especially the hole, the colder the more you get below, the place where your belly is bent, there is a layer of thin ice that is not slippery on the rock. If they weren't on the crampons and the ice axes, they wouldn't have been able to climb down.

Twenty minutes later.

The three of them had already stepped on the ice lump filled with the bottom of the hole.

This place is nearly 150 meters away from the entrance of the cave. The space of the cave is already amazingly large, and the best part is that Grain Rain cannot hear the edge.

Gu Yu knocked on the rock wall with an ice axe, listened with his ears, and found that his hearing was far from the end of the ice block. Then he felt relieved and said:

"It's okay, the ice layer is thicker, so we can't break it."

After hearing this, Maoyan and Lejie untied the rope that bound their bodies and walked towards the center of the ice with the wave of Guyu.

After walking a few steps, Guyu stopped and said:

"There is an ice hole in front, about two meters deep. We have to jump in one by one about ten seconds apart to save ourselves from hitting others."

Lejie and Maoyan nodded.

This is why Guyu must be brought down, because only Guyu can go along the intricate ice holes to the closest place to Professor Jack Sheng.

"Crack!"

Sister Le and Guyu turned on the searchlights above their heads.

The hairy eyes don't need it, after all, it's really invisible.

Guyu took a few steps and slid into an ice hole and disappeared.

Sister Le silently counted dozens of times, took a few steps forward, and also slid in.

As Gu Yu said, the ice pit is about two meters deep and the bottom space is not large, but there are three horizontal ice caves of different sizes that extend into the distance in a roundabout way.

The hairy eyes fell and the three of them gathered together.

Gu Yu pointed to the tiniest ice cave and said:

"We want to climb this thin hole. After entering ten meters, the hole will begin to tilt downwards. There are many places to turn. There are also many raised ice edges on the walls, some of which are extremely sharp. We must always use crampons and ice axes to control the speed, otherwise if we are not careful, we will be distilled by those sharp ice edges."

Hairy breathed a long breath and nodded.

With this narrow terrain, smooth ice surface, and downhill, it is not that easy to avoid those sharp ice edges.

Sister Lu looked at Maoyan. She knew that Maoyan's physical strength was not good, so she pondered:

"Maoyan, you can wait here."

Maoyan shook his head and said:

"I can't judge Professor Jackson's death time and how he died before the first scene. This is my job, and I have no choice but to worry about me. I'm at the end and you are in front. There's nothing to worry about."

Sister Lu nodded and waved her hand at Guyu.

Guyu took a deep breath, moved his shoulders and waist, gritted his teeth, and drilled into the thin hole.

The ice cave is very thin and narrow, and the diameter is probably less than one meter. They can only lie on the ground like insects, crawl and walk, and it is difficult to kneel down.

It’s okay to say that it was smooth after all. Later, the slope of the thin hole became bigger and bigger, and Guyu was so tired that he felt sweat on his back in the cold hole.

He had to press the ice wall with his feet all the time, and use an ice axe to stick in front of him like a brake, carefully avoiding the sharp ice edges that may appear at any time.

"Be careful, there are several sharp ice ridges in front of them, like the big mouth of a monster. Follow me closely, the safe passage should not exceed 60 cm in width."

The sister-in-law behind her breathed a long breath. She was lying down and she would definitely not be able to get through, but she was on the side.

Guyu's speed slowed down significantly, and the ice axe was almost ten centimeters and ten centimeters and the crampons on their feet took turns to brake and slow down.

The sweat beads on the forehead slid down the corners of the eyes, making the eyes hurt.

His wrists were already sore, but he did not dare to slack off at all, because as long as he could not stop, he would be scratched by a pile of ice fangs not far ahead.

"Crack!"

A crisp sound.

After the ice axe on Guyu's hand got stuck into the ice layer, a small piece of ice unexpectedly lifted up, which was the resistance to prevent Guyu from sliding.

"Swoosh!"

As the ice axe was empty, Gu Yu suddenly stretched forward. He hurriedly opened his legs and used the crampons on the soles of his feet to scratch the ice walls on both sides.

A series of harsh friction sounds of "creak" failed to stop the inertia of Grain Rain.
