"Which increase do you think is more appropriate?" Xu Xin looked at his historical increase, thinking, and asked Ji Chaoyang.
"Hearing amplification, I feel it is the most suitable." Ji Chaoyang was also thinking, "This mountain is too strange. During the climb, hearing amplification can at least allow us to detect abnormalities around us as quickly as possible."
Xu Xin thought almost the same as he did.
"Have you ever had a jump boost?"
"What is that? Never." Ji Chao shook his head.
The increase in his jumping ability is actually a very good choice. If he falls from a height, he can easily stabilize his body like a cat, without panicking at all, and can easily deal with the crisis.
After hesitating for a few seconds, he finally chose hearing amplification.
Without Coco following him, his own perception became particularly important. Moreover, during the rock climbing process, his vision was basically focused on the rock wall. At this time, the only way to perceive the surrounding conditions was through hearing.
And if he falls, he has the hook, so it won't be a big problem.
The moment I choose hearing amplification, the sounds around me become very clear.
Xu Xin ate all the fruits that could bring him buffs, such as red berries, apples, oranges, strawberries, etc. After stacking all the status on his body, he and Ji Chaoyang looked at each other, and both of them exerted force with their arms and climbed to more than 50 meters.
He had been keeping his eyes on Ji Chaoyang this time, but after climbing more than 50 meters, his vision suddenly became blurred, and his eyes felt sore and he couldn't help blinking.
In the blink of an eye, Ji Chaoyang disappeared, and he was the only one left around.
With the hearing enhancement, Xu Xin could still hear some rustling sounds in the jungle, as well as Ji Chaoyang's breathing and heartbeat, but after climbing more than 50 meters, these sounds completely disappeared.
He seemed to have really entered a world that belonged only to him.
Even the sky shrouded in fog seemed to become a little darker.
Fortunately, the surroundings were very quiet, without even the sound of wind, which made Xu Xin feel relieved.
Calming himself, he began to climb upwards.
Arm strength enhancement is really a good helper for rock climbing, just like jumping ability enhancement is designed for jumping, arm strength enhancement seems to be designed for rock climbing.
Every time he exerted force with his arms, his entire body would be driven up two or three meters.
The rock wall of the Stone Pillar Peak was uneven, and he could find a very suitable place to hold on with every step. Although there might be some snow on it and the stones on the rock wall were slightly slippery, he was still able to climb up steadily with his caution and strong strength.
It was very quiet around, really quiet. Apart from the sound of him climbing, there was not even the sound of wind.
After climbing for several minutes, Xu Xin found a more stable foothold, grabbed the rock wall with both hands, took a short breath, and looked down.
The ground was already quite far away from him, estimated to be about two hundred meters away.
He looked up again, and the top of the giant stone pillar was still shrouded in clouds and mist, out of reach.
His current position was a little different from when he was down there.
The temperature has dropped.
It is morning now and the sun is just rising. The sunlight is still blocked by fog, so the temperature has not risen much.
Just now at the foot of the mountain, it was about minus 20 degrees Celsius.
This temperature is not low. The snow protective clothing sold in the points mall can withstand the lowest temperature of minus 15 degrees. Therefore, at this temperature, most survivors cannot go out to explore.
But Xu Xin felt that the temperature was lower now, and as he climbed, the temperature dropped quite quickly.
On Earth, the temperature drops by about 0.6 degrees Celsius for every 100 meters of altitude increase. That is to say, from the dividing line of about 50 meters to his current position, according to calculations, the temperature has dropped by about 1 degree, which is about right.
But he felt that now, at an altitude of 200 meters, the temperature had definitely dropped by more than one or two degrees compared to before.
Although he was wearing a snow fox scarf and did not feel the biting cold, he was still aware of the temperature.
The temperature gave him the feeling of being around minus 25 degrees Celsius, right
How could it drop so fast
Xu Xin hung on the rock wall with one hand and tightened the snow fox scarf with the other.
This thing can't be loose. If it loosens and falls down, he will really freeze to death.
I should have made a few more and put them in my backpack as a backup.
He tied the scarf into a knot around his neck with one hand to prevent it from falling off, and then climbed up again.
After climbing about three hundred meters, Xu Xin found a small cave on the rock wall.
It is called a cave, but in fact it is just a larger pit where he can sit down and take a rest.
After climbing three hundred meters, he already felt that the muscles in his arms were a little tired. He needed to give his arm muscles, which had been working all the time, a little rest. Otherwise, in such a cold altitude, he always felt the risk of cramps.
Sitting in the cave, Xu Xin rubbed his arms.
The surroundings were still very quiet, without even the sound of wind.
The mist in the air seemed to be solidified, stagnating around the giant stone pillars without moving at all. If it weren't for the watch on his hand that could still tell the time, he would have even doubted whether time had stopped in this strange space.
He leaned forward and looked upward.
Although he kept saying that the peak was thousands of meters high, he had no idea how high it was just by looking at it. The general height was between one thousand and two thousand meters.
He had only been climbing for about ten minutes and had already reached a height of more than three hundred meters.
It was also thanks to his increased arm strength that he could climb so fast, by climbing two or three meters at a time.
If he continued at this pace, he might be able to reach the top within an hour!
Of course, Xu Xin is not such an optimistic and naive person. He does not think that this activity will be so simple.
If he climbs higher, he might encounter some dangerous situations, so he must recover his strength!
The cave where he is sitting now is actually the beginning of the change.
Three hundred meters of rock climbing below, he had never seen such a cave, or rather a big pit.
And above...
He leaned over and looked up again.
Even though the field of vision was very small, Xu Xin could still see that there were quite a few such caves above.
This giant peak seems to be divided into sections from bottom to top, and the stone walls of each section are different.
If the distance from the ground to fifty meters is the first section, where the rock wall is rough and easy to climb, and the temperature is relatively high, then the distance from fifty meters to three hundred meters is the second section, where the rock is smoother and easier to slip, and communications are prohibited.
Now, after reaching over 300 meters, we have entered the third section.
I don't know what I will experience during this period. However, the temperature here is really low.
I always feel that it is minus 40 degrees Celsius.
After resting enough, Xu Xin grabbed the rock wall and started climbing up again.
Sure enough, just as he had just expected, the surrounding environment had changed a lot.
The rock wall was no longer the slightly smooth stone, but rather rough, making it easier for Xu Xin to hold on.
However, every time he grabbed onto the rock, an icy chill would pass from his palms into his body. Even the snow fox scarf could not block the chill that directly penetrated his skin and entered his body.
Xu Xin finally understood why the temperature dropped so quickly while climbing. The temperature here was so low because of these rock walls! The rock walls were extremely cold and were actively emitting cold air, thus affecting the area below!
The rock that made his hands feel cold couldn't be less than minus fifty degrees Celsius!
So cool!
Fortunately, although the temperature of the rock is low, the temperature of the air is not too low.
Under the influence of the sun, the air temperature has been maintained at around minus 40 degrees Celsius, which is still within the tolerance range of the snow fox scarf.
Xu Xin exhaled a breath of white air.
He went into another cave.
In this environment, my hands were constantly being eroded by the cold and my physical energy consumption was also enormous.
Even though he had Xing (Blue) who could slowly restore his strength, it was unable to offset this level of consumption.
All sides of the cave are made of stone walls that emit cold air. Because of this, the temperature inside the cave is very low, almost reaching the limit that the snow fox scarf can withstand.
Xu Xin cleared the snow at the entrance of the cave, but he didn't dare to sit down because it was too cold and his butt was freezing.
But this small cave was not high enough, only about 1.2 meters high. He had no choice but to squat in the cave and take a rest.
Fortunately, his purple-grade steel boots still performed well. Perhaps because of the thick soles, at least his feet did not feel the biting cold.
After hesitating for a moment, Xu Xin took out the energy core fragment.
No, it's too cold. Warm up a little.
The surroundings were immediately illuminated by bright white light, and the temperature began to rise.
Minus fifty degrees, minus forty degrees, minus thirty degrees...
Twenty degrees above zero!
Under the influence of the energy core fragments, the surrounding temperature directly rose to normal temperature!
Xu Xin also breathed a sigh of relief.
So comfortable!
This energy core fragment can actually restore such a low temperature to normal!
However, he did not dare to do this for a long time. Just from the light of the energy core fragments, it can be seen that this time the light, although still soft and not dazzling, is many times brighter than before.
In other words, the energy core fragments are consuming the energy within them at a very fast rate to maintain the surrounding temperature!
Xu Xin enjoyed the normal temperature for only one minute before putting away the energy core fragments.
This precious energy is not for him to enjoy. He can use it when the temperature becomes unbearable.
Just as he was about to step out of this area again, a slight sound suddenly came into his ears.
"Card… "
He suddenly stopped where he was, with his ears perked up to catch the sudden sound.
After climbing for so long, this was the first time he heard a sound from something other than himself, and he instantly became extremely nervous.
"Ka..." A slight sound, as if something was cracking slightly.
The sound was very close to him, probably just above his head, about five or six meters above!
Xu Xin didn't move and waited there for a long time, but the sound did not come again.
… No time wasted. His hearing amplification had already detected the location where the sound came from. Since it was no longer heard, he would go and look for it himself!
His hands grabbed the rock wall again, and the icy coldness passed from the palms of his hands into his body, making him shiver.
He did not stop, but exerted force with his arms and climbed up another two or three meters.
Then, he grabbed the stone wall again, and immediately grabbed a cave entrance with both hands, while also plunging into the snow.
Compared to the extremely cold rock wall, the snow is actually warmer.
He exerted more force with his arms and stepped into the cave.
So cold…
Xu Xin shuddered.
What he entered now was a real cave, not the pits in the wall where he could only squat.
The cave is two meters high, which is enough for him to stand and walk. Running might not be possible because he would hit his head.
Yes, the cave is deep.
It was pitch black inside, but with the night vision ability of Red Berry, Xu Xin could still see clearly.
A narrow cave, two meters high and less than one meter wide, has a corner after going more than ten meters deep. Going deeper, Xu Xin could no longer be seen at the entrance of the cave.
The slight sound, as if something was breaking, that just reached his ears came from this cave.
The walls of the cave were all made of this kind of rock that exuded a cold atmosphere. Just standing at the entrance of the cave, Xu Xin could feel the coldness pouring out. The entrance of the cave was already as cold as minus fifty degrees Celsius, and the temperature inside was probably even lower.
This narrow cave suspended hundreds of meters in the air is truly mysterious. What is inside
However, it seemed to have nothing to do with his goal of reaching the summit.
"Ka..." Another slight sound came from the cave, causing Xu Xin's heart to skip a beat.
Should I go in and take a look, or just leave
