Sherpa's worries were not unreasonable, and Wang Xingguo was thinking hard about how to use a master lock to protect the two of them through that abyss.

Wang Xingguo is now facing not only the problem of insufficient equipment, under normal circumstances, in passing through dangerous areas, it is necessary to play a fixed point, either with an electric drill and a pid into the rock, or in the rock crevice to plug the rock plug, at this time Wang Xingguo has no pitons and electric drills in his hand, and there is no rock plug, he only has a main lock in his hand and can barely reach the opposite rope connected to the opposite side, Xia Ruobing has never seen anyone who can complete such a difficult climb with the help of such a rudimentary equipment, if Wang Xingguo fails, only himself is left, Xia Ruobing knew very well that the probability of her survival had almost dropped to zero!

Wang Xingguo has decided to take this risk, he took the main lock and looked at the stone crack in the cave wall, he wanted to find a suitable stone crack and stuff the main lock into it, so that it could not only be used as a rock plug, but also play the role of the main lock to pull the rope.

"Xia Ruobing, I need your help." Wang Xingguo looked at the nearby cave wall, there was no place to meet this requirement, he shone a flashlight on the edge of the abyss, where he saw a cracked rock crevice, which should be able to meet this requirement.

"You make me a fixed point first, and I'll climb to the middle, stuff the main lock into the rock crevice, and make a relay protection station......"

"But...... How can I hold you? Xia Ruobing was worried.

"I will use the concave position of this stone to increase the friction, you must follow my speed to release the rope, don't let the rope slip out, in case I fall, you can't pull me with the protector, remember to let go!" Don't carry ...... hard," Wang Xingguo explained carefully, tied a protective knot on his body, and prepared to go.

"Wang Xingguo, let's go back......" Xia Ruobing felt very scared, she took Wang Xingguo's hand and said.

"I'm going to make it, give me the headlamp." Wang Xingguo gently squeezed Xia Ruobing's hand, her hand was cold, and he comforted, when you need to climb, it is impossible to climb the cliff with a flashlight in one hand and the other hand, Xia Ruobing's headlamp can be of great help at this time......

"What if it ......" Xia Ruobing didn't know why, she had a feeling of wanting to cry, maybe because of worry, maybe because of fear, or because of something else.

"Xia Ruobing, there is no case! Even if I'm dead, you'll have to crawl over it as best you can! There is hope to live! Wang Xingguo grabbed Xia Ruobing's shoulders and interrupted her rudely,

Xia Ruobing's second half of his words was frightened back by Wang Xingguo's roughness, so he could only nod.

"Remember, as long as you don't die, you can live! If I can do it, you can do it too! You still have half a copy of Lu Wen that you haven't added, and your parents' last wishes have not been fulfilled! Give me courage! ”

Perhaps it was this sentence that made Xia Ruobing regain her confidence, and she nodded vigorously.

Wang Xingguo put on the headlamp and turned off the flashlight, he wanted to put it in his pocket, but after thinking about it, he stuffed it into Xia Ruobing's hand: "You take it, in case I don't go over, you can still hold on." ”

After checking the preparations, he said again: "If I fall and you can't hold it, remember to let go!" You must know how to let go! ”

Xia Ruobing was speechless, nervous, scared, panicked, facing unknown hopes, all kinds of emotions occupied her heart, she couldn't speak, Wang Xingguo had already decided, she looked up at the opposite side, the soft light of the cave mouth came through, as if beckoning to her.

Xia Ruobing gritted her teeth, drove away the uneasy emotions in her heart, and secretly said in her heart: "It will be successful!" It will definitely work! ”

Wang Xingguo made an OK gesture: "Are you ready?" Let's go! ”

Xia Ruobing nodded, took a few steps back, and passed the rope through the protector: "Wang Xingguo, you have to be careful!" ”

If Wang Xingguo misses and falls, Xia Ruobing can help him stabilize the situation with the help of the protector, the protector is to rely on the rope and its internal friction surface or squeeze the rope to increase friction, so as to achieve the purpose of using a small force to control his descending speed when descending, the protector can also use this principle to protect the climbing of others, theoretically with the help of the protector and fixed points, Xia Ruobing can protect the safety of people who weigh twice his weight, as long as he falls no more than 5 meters, But at this time, there is no fixed point, Xia Ruobing can only rely on his own weight to resist the force of the fall, Wang Xingguo's weight is about 1.5 times that of Xia Ruobing, as long as the distance he falls is more than 3 meters, Xia Ruobing will be pulled into the abyss together if he doesn't let go.

So Wang Xingguo warned her that she must know how to let go, and if she fails, at least leave Xia Ruobing with hope of survival.

Xia Ruobing took a few steps back, sat down in a relatively flat place, the lower the center of gravity, the stronger the ability to resist the fall, there is no bulge to use here, and it can almost be regarded as a smooth and downward slope, Xia Ruobing thought about it, and leaned towards the edge of the cave wall, there is at least one more friction surface here, lying back with his body, and supporting the corner of the cave wall and the bottom of the cave with his feet.

Wang Xingguo saw Xia Ruobing's movements and gave her a thumbs up - telling her that he was ready to go.

Wang Xingguo took a deep breath, he understood how dangerous these loose stones would be, 70 kilograms of weight, this is not a problem when there is a stable climbing point, he cannot escape the constraints of the earth's gravity, Wang Xingguo may pay the price of his life for any mistake in judgment.

"Xia Ruobing, I'm going to start, are you ready?" Wang Xingguo once again confirmed Xia Ruobing's status.

After carefully observing the cave wall, Wang Xingguo had to choose a better climbing route, he felt that it was best to climb down first, and then bypass the part that looked the most unstable, at this time communication with Xia Ruobing was very important, after Xia Ruobing was half-lying, he couldn't see his movements, they could only use their voices to keep in touch.

"Good...... Okay......" Xia Ruobing's voice trembled a little, and she didn't know if she was ready.

"Don't be afraid, believe in yourself." Wang Xingguo gave a word of encouragement, and then said, "I'll start." ”

"Good!" Xia Ruobing mustered up her courage, her hand tightly grasped the rope on the protector, she didn't know if she was nervous or too hard, she felt her body tremble slightly.

"Drop the rope!" Wang Xingguo had already poked his feet down, and the rope sleeve on his body was pulling him, and his feet were still close to stepping on the fixed point he chose.

Xia Ruobing's hand loosened slightly, but it quickly clenched again, Wang Xingguo leaned down, but he didn't step on the stone as expected, and his hand was still very embarrassed and half-grabbed the edge of the cliff.

Xia Ruobing was still a little nervous, and only released about 10 centimeters of rope, she felt that it might be safer to release it slowly.

"Put it again!" Wang Xingguo shouted.

Xia Ruobing let go again, and then quickly clenched, Wang Xingguo's toes reached the stone, but his body was suspended.

"Follow my speed and release the rope, don't be afraid!" Wang Xingguo was embarrassed and half-hanging, his toes were half-stepping on the stone, and his hands had to be balanced hard, so that the embarrassing posture consumed more physical strength.

Under normal circumstances, it should be up to the climber to master the rhythm and the protector cooperates, but if the protector is too nervous, it will overstep the trap and limit the climber's play, which will make the climber more physically demanding.

"Xia Ruobing, listen to my command to release the rope!" Wang Xingguo thought about it, Xia Ruobing was afraid that she would not be able to control Wang Xingguo's fall, if the rope was shorter, even if it fell, it would be easier to control, but this would seriously restrict Wang Xingguo's play, Wang Xingguo shouted, "Follow my speed, put another 30 centimeters!" Don't worry, I'm in control. ”

Xia Ruobing gritted his teeth, according to Wang Xingguo's instructions, released a 30 cm rope, Wang Xingguo stood firmly on the stone, this stone was well chosen, although it was a little loose but much more stable than other stones, after Wang Xingguo stood firm, he looked at the surrounding environment, stretched out his left hand, and planned to reach the protruding stone, with the help of the headlamp, Wang Xingguo saw that the stone was abruptly there, whether it was from the shape or size, it was very suitable for hand.

Wang Xingguo grasped the stone steadily, and then he had to gradually increase his strength to test whether it could support his weight, Wang Xingguo just increased his strength a little, and heard the stone "click", and then the stone came loose from the crack in the stone, Wang Xingguo retracted his hand.
