"Xia Ruobing! It's your turn! The rest of the stage was a piece of cake for Wang Xingguo, who climbed to the platform without much effort, and Wang Xingguo shouted to the other side while unbuckling his seat belt.

"I ...... Wait a minute...... Wait a while......" When it was his turn to fight, Xia Ruobing suddenly felt that he was not up to the task.

"You take a break, move your hands and feet, I've explored the line, it should be fine."

Xia Ruobing consumed some physical energy to protect Wang Xingguo just now, and she should be given some time to recover.

As he spoke, Wang Xingguo unbuckled his seat belt, and when he saw that the slope was white, Wang Xingguo smoothed the rope, wound the rope around a bulge on the side of the rock wall, tied a knot, and illuminated the ground with a headlamp.

Wang Xingguo was shocked, what kind of stone is this thing? It's a paved ground of teeth and scattered bones!

Wang Xingguo casually pulled on the ground, and pulled the teeth of one hand, which were basically big teeth, some of which had enamel left, and some of which were relatively well preserved, and occasionally a few pieces of mandible remains, but the bones of other parts were difficult to find......

These teeth and bones were almost paved on the ground, Wang Xingguo walked up for a short distance, there was almost no place to get his feet, and in some places he even stepped on them, but they didn't pass the surface of his feet, and people couldn't help but slip when they stepped on them.

"Xia Ruobing, I'll clean up the passage first, don't come down first!" Wang Xingguo turned around and shouted, at this time, we must communicate well, in case Xia Ruobing misunderstands that he has done a good job of protection and starts climbing, it will be dangerous.

"yes, I see." Xia Ruobing replied, in fact, she was not ready at all, and the thought of climbing with almost no protection made her heart go up and down.

Xia Ruobing was preparing slowly, and heard the sound of "bang, bang, bang" over there, it was Wang Xingguo's teeth and bones cleaning the ground, but there were too many pavings here, Wang Xingguo could only sweep with his feet on the ground, and the sound was like the sound of using a big broom to sweep stones.

"Wang Xingguo, what are you doing?" Xia Ruobing felt that this sound was very abnormal, and asked loudly.

"It's okay...... It's okay, I'm cleaning the ground. Wang Xingguo thought about it and felt that it was better not to tell Xia Ruobing the truth.

Wang Xingguo adhered to the edge of the cave wall, and cleaned a passage more than one meter wide and 30 meters long along the slope, when Xia Ruobing and others could climb, Wang Xingguo had to follow her speed to collect the rope, Wang Xingguo felt that it would be safer to walk all the way up to collect the rope, so he had to ensure that the ground was clean enough and would not let himself slip.

The cave wall here is still relatively rough, perhaps because of geological extrusion, there are protrusions and deformations in many places, Wang Xingguo found a relatively large protrusion, which allows him to hold it firmly with his feet.

"Xia Ruobing, are you ready? I'm ready! Wang Xingguo felt that everything was ready, so he sent Xia Ruobing, he urged.

"I ...... Good...... All right! Xia Ruobing replied stiffly, thinking about it and not at ease, he checked the seat belt on his body and the rope that passed through the seat belt bearing ring.

The figure-8 knot passed through the load-bearing ring firmly, Xia Ruobing was not at ease, and tied a protective knot, but she was still not at ease, hesitated for a while, Wang Xingguo urged again, and Xia Ruobing walked to the edge of the cliff slowly.

The light of the headlamp was not strong, Wang Xingguo could only see Xia Ruobing's figure swaying on the edge of the cliff, but the details were not clear, and he shouted to her: "Go down first, there is a big stone there is very stable, and then to the left, I will use the light to illuminate the line, it's okay, you pay attention to the stones, don't move it if it is loose!" ”

"This ...... Wang Xingguo, is the main lock okay? Xia Ruobing is still not confident, although Wang Xingguo made a protection station in the stone crevice with the main lock stuck in the middle section, but this is a wrong textbook model according to the climbing standards, Xia Ruobing considered whether the main lock could withstand the force of falling 20 meters by himself in case he missed.

"Xia Ruobing, you don't have to worry!" Wang Xingguo knew the reason for her hesitation, but at this time, where to set up a protection station for the correct model of textbooks?

Wang Xingguo has received strict survival training, rock climbing is also an important subject in survival training, the basic principle of all survival training is to use everything at hand to ensure safety, if there is better safety equipment, there are other ways Wang Xingguo will not do this, but now only by doing so can we strive for a glimmer of life!

As Xia Ruobing climbed, Wang Xingguo continued to retract the rope, as long as Xia Ruobing started to climb, as the rope was shortened, she became more and more safe, Wang Xingguo confirmed the position of the main lock card, this simple protection station is enough to withstand Xia Ruobing's 5-meter falling force.

"Good...... All right! Now, Xia Ruobing had to muster up the courage to fight for a chance to survive, she gritted her teeth and climbed off the cliff.

Wang Xingguo has explored the line and will give her guidance, Wang Xingguo is more dangerous the further he climbs, but Xia Ruobing has relay protection, but the more he climbs forward, the safer it is, as long as the remaining section of the relay protection position is much simpler, it is simply a leisurely stroll!

What Wang Xingguo is most worried about is the upper part of the section where he is about to reach the relay protection position, Wang Xingguo has already planned it, this section is only two meters long, let Xia Ruobing let go, and Wang Xingguo will drag her up to the platform.

It must be said that Wang Xingguo calculated every step, not only comprehensive and accurate, if according to his calculations, the possibility of the main lock recovery is still very large, but all Wang Xingguo's calculations depend on Xia Ruobing's play, which is also what Wang Xingguo is most worried about.

Xia Ruobing is not good at rock climbing, women's upper body strength is generally weak, and coordination ability is not too good, unless deliberately exercised, Xia Ruobing's rock climbing skills are better than ordinary girls, but they are far from reaching the semi-professional level, at this time, the dark abyss is pressing Xia Ruobing's nerves, so the speed is very slow.

The slower the speed, the greater Xia Ruobing's consumption, which is more likely to cause muscle fatigue, Wang Xingguo was a little anxious, and urged: "Xia Ruobing, speed up, or you will be tired!" ”

Xia Ruobing was lying on the edge of a stone, under her feet was a fixed point that could only accommodate half of the soles of her feet, her hands were stubbornly climbing a stone crack above, covered in hot sweat, her hair was stained on her forehead, and the sweat droplets slowly flowed down her hair and flowed into her eyes, which stimulated her to blink continuously, she wanted to wipe her eyes with her hands, but she was afraid that she would fall if she let go.

At this time, Xia Ruobing was still about ten meters away from the relay point, but she had already used up almost 20 minutes.

"I ...... I'm tired! Xia Ruobing felt that her arms were spasming, and after a while, her thighs were also spasming, continuous mental tension, and she did not supplement enough nutrients, at this time, the electrolytes in her body went through a burst of high-intensity activity, reminding her that her body began to lack potassium.

Xia Ruobing tried hard to control the spasms, which consumed her physical energy even more, and her feet on the small fixed point began to tremble slightly.

Wang Xingguo was in a hurry, this section was the most difficult, there was almost no foothold to rest, Xia Ruobing was lying on the edge of the rock wall like this, stepping on it and not stepping on it firmly, and picking it up and not firmly, this section needed to pass through in one go, but Xia Ruobing stopped! It's deadly!

"Don't stop, come on, don't stop, the more you stop, the more tired you get! And ten meters! It's less than ten meters away! Wang Xingguo urged, a chill rose up his back, Wang Xingguo could ensure that the main lock could withstand Xia Ruobing's 5-meter falling force, but in case......

If in case, the main lock is loosened, Xia Ruobing's best result is to shoot on the cliff, Wang Xingguo can barely support it, Wang Xingguo has no help from equipment, at this time he carries the rope on his shoulder in a simple way, and uses the friction between his back and shoulders to protect, he can ensure that Xia Ruobing does not fall more than 10 meters to the greatest extent, and even if Wang Xingguo tries his best, he can't stop Xia Ruobing from falling!

If Xia Ruobing doesn't pass this most dangerous distance as soon as possible, if the main lock is loosened, she will only have a dead end, and she will pull Wang Xingguo down the abyss together!

Wang Xingguo had to find a way to let her hurry through this section, all the way over, Wang Xingguo followed Xia Ruobing's speed to close the rope, in order to make her feel at ease, the rope would be slightly tighter when retracting, Xia Ruobing felt the pulling power of the rope, and she would feel a lot more at ease.

"Xia Ruobing, I'll give you 5 seconds to go to the next point, otherwise I'll let go of the rope!" Wang Xingguo threatened.
