In the live broadcast room, the audience posted barrages one after another, worried about Xu Ye's safety.

About two seconds passed.

In the dark cave, there were suddenly a few spitting and scolding sounds.

"Whew...... I'm fine, it's just some dirt and gravel, don't worry!"

Chen Xu got up from the ground and approached the drone.

With the pitiful light emitted from the drone screen, the audience vaguely saw the outline of Xu Ye's face, as if there was no blood, and they were relieved.

He patted the dirt off his body and leaned against the wall, waiting for his pupils to adjust to the darkness around him.

"If you have such an accident in a cave or tunnel, you must not panic, first lean against a safe wall to avoid being hit by the secondary debris collapse, and then stay as calm as possible, and wait until your eyes are used to the surrounding environment, and then judge which way to flee. ”

"In the cave, the most taboo thing is to run in a panic, so it's easy to get lost, if the cave is very large, the consequences of doing so will be trapped here alive!"

"If you really can't see at all, then I can teach you the easiest way to do it, which is to walk by the wall, and from the way we came, you can see that this cave is a single road. ”

"So, as long as we touch any wall on the left and right, we can easily go back the way we came!"

After Chen Xu explained a few words, he personally demonstrated it to everyone.

"666, Xu Ye didn't panic at all, if this were me, I guess I would have been scared to pee!"

"If you really want to get lost and can't get out, then God has done it!"

"I'm so scared, hold me tight!"

"It's like Tomb Raider!"

The audience posted a lot of barrages, but Chen Xu didn't look at the screen anymore, he first had to let his eyes adjust to the darkness around him.

However, after waiting for a full minute, his pupils were completely dilated, but he felt that his vision still did not improve, and it was still pitch black, and he could not see clearly.

There is no way, the whole cave is sealed, and the opening is very narrow, and there is still a narrow cave outside the opening, and the light source cannot enter at all.

As for the screen light of the drone, it can be said that it is a joke.

Not even the light of the torches could shine too clearly, let alone the tiny screen.

It is precisely because of this faint light that it looms on Xu Ye's body, coupled with the extremely dark environment around him, and the sound of his heavy breathing, it looks like a thriller movie.

After walking for about a minute, Chen Xu exhaled and said to the camera: "It is easy for people to lose their sense of direction in the dark, even if they touch the wall, but you can't judge how far you have gone and how far ahead." ”

"Here, I'm going to teach you a very easy way to feel the air currents in the air, because the cave is airtight, the air can't flow. ”

"The only place where air can flow is the entrance to the cave, which is the only entrance to the outside world, and it creates a strong air current, so when you look for an exit, if you feel an air flow or a breeze blowing on your face, it means that you are in the wrong direction!"

As he spoke, he closed his eyes and carefully sensed the sound of the wind in the air with his skin.

Sure enough, a faint stream of air hit him in the face.

He smiled slightly, "It seems that the exit is not far from me!"

After saying this, Chen Xu walked a distance of less than a few dozen meters, and successfully found the entrance to the cave that he had just entered.

The moment he walked out of the crack in the mountain, the dazzling sunlight immediately hit his face, causing him to subconsciously close his eyes.

"Whew...... I used to hate the sun on Viper Island because it was so hot, but I have to admit that after dozens of minutes of darkness in the cave, I really miss 'it' now!"

After a few words of hip-hopping with the audience, after resting for a while, Chen Xu made a torch again and drilled into the cave again, ready to explore the unfinished section just now.

Because of the previous groping, the second time he entered, he seemed particularly relaxed.

In less than fifteen minutes, he had inspected the second cave, but found no valuable clues.

However, it is a good thing to be congratulated to find a source of water that is still "semi-stable" and clean.

In the blink of an eye, the time quickly reached noon.

Chen Xu caught a non-venomous grass snake in the grass, which was the first non-venomous snake he encountered after coming to Viper Island.

It's ridiculous to say, according to the snake data published by National Geographic, the number of non-venomous snakes accounts for more than 60% of the total number of snakes.

But here, non-venomous snakes have become a "rare species".

After lunch, Chen Xu continued to embark on a treasure hunting journey.

The system only gave him fifteen days, and if he wanted to find the Inca gold treasure in such a short time, he couldn't rest casually.

In case of bad luck, the mark left by a Guarani warrior alone is likely to be found for five or six days!

In the afternoon, Chen Xu returned to the boulder slope on the northern shore of the island.

He was always convinced that if the Guarani warriors did leave a mark to guide the way, they must still be near the landing site.

So he re-routed along the edge of the West Coast, searching for any man-made clues or traces of human activity.

About an hour later, Chen Xu climbed onto a huge rock.

But the moment he stood up, he didn't expect that there was a huge ravine in front of him, and the rough sea below, and the other side of the ravine was at least a few dozen meters away from him.

The entire ravine is about 50 meters deep, and the bottom is full of huge talc.

Chen Xu squinted his eyes, observed for a moment, and said, "It seems that there was a very serious rock collapse here, and those boulders below should have fallen from the ravine in the middle of the ravine." ”

"I couldn't go straight there, I had to go around the ravine, which meant I had to venture through the rock shelf where a landslide could happen at any moment...... Looks like I'm going to have to be careful!"

Without hesitation, he began to walk along the edge of the ravine towards the rocky shelf at the edge of the landslide ravine.

Along the way, Chen Xu was extremely cautious, with his body low, climbing the edge of the rock with both hands, and each foot was very stable, completely in a climbing posture.

Of course, he didn't forget to take a closer look at the various markings on these rocks.

And at this moment, a triangular cave entrance appeared in his eyes.
