You must know that this time, but if they have to hang down to a depth of 100 meters, it is very likely that the stones that bind the ropes will be subjected to tremendous pressure for several hours, and it will be difficult to ensure that the knots of these ropes on the rocks will not make any mistakes, so this is a problem that must be solved.

Otherwise, even if there is a little accident at that time, it will really be the end.

Zhang Meng took the 'cushion' that he and Lady had hand-knitted before, and then tied three ropes with the word 'Pin' on the cushion, just like a swing.

I also fastened the rings of the two feet that I had stepped on before, and now it was really much more stable.

However, Zhang Meng was still slightly apprehensive, this is a abyss of hundreds of meters below! If you fall, you may not even be able to find your bones, and anyone will feel panicked.

"There is no fat man if the tie is strong, otherwise there is no need to save a few more!"

"Enough is enough, you can't fucking go down...... the fat man got angry, grabbed Zhang Meng and threw him out.

Zhang Meng took a deep breath, at this time, he stepped on the rock wall of the cliff, but he was not so panicked, and the preparations they had made before were indeed very useful, at this time Zhang Meng didn't even feel the pulling force of the rope in his body, except for the whole person leaning up and walking against the wall, there was really no strange feeling at all.

"Be careful, don't let that stone cut the rope!"

Xiaolou above shouted loudly, she also had a heart in her chest, for fear that Zhang Meng would have some accidents.

"Hmm."

Zhang Meng tried to straighten his feet as much as possible, making sure that the rope that tied him to the rock did not have a chance to touch.

Zhang Meng's eyes suddenly froze, he just landed on a fist-sized stone, probably accidentally stepped on the front of the stone, Zhang Meng only felt that the stone was actually cut a few centimeters deep like a knife cutting tofu!

If it weren't for the thick soles of his new shoes, I'm afraid the soles of his feet would be useless this time.

Zhang Meng let out a cold sweat, and he quickly let his feet fall in a safe place, which was a little relieved.

I don't know what is going on, these stones are not rounded, but polygons made of at least several faces, and the incisions between each cut are as sharp as knives. I don't know how much time it took the designer to polish these stones.

Zhang Meng retracted his thoughts, and he slowly fell to the stone he had seen before that was like a stalagmite spitting out.

He carefully found a place to stay, and then carefully examined the stone, which had four sharp corners, which was relatively small compared to the others. And it's almost as thick as a thigh, so I think it should be able to withstand more force.

Zhang Meng carefully pulled out a hammer from his pocket, and then slammed it down, only to find that there was no trace on the surface of the stone.

Sure enough, as Wang Daxian said, this stone can definitely withstand the strength of a thousand catties, but Zhang Meng was relieved.

He nodded, and took out the Mitsubishi chisel, ready to chisel out a groove that would hold the rope.

Fortunately, they had made that stool before, otherwise he would have been able to use both hands now, and he would not be afraid of falling down at all.

Zhang Meng twisted tentatively a few times, and found that no matter how he dealt with it, he was still at ease, and he was completely relieved, and then carefully used the tip of the Mitsubishi chisel, plus the hammer, to smash out a groove three or four thumb thick.

Then he carefully smoothed all the four sharp surfaces of this 'stalagmite', and Zhang Meng was busy sweating, grinding his hands into blisters.

I don't know how long it took, but he touched it with his hand, and finally there was no longer that sharp touch. Zhang Meng frowned, pressed his fingers down hard, and then rubbed it vigorously in the groove he had dug out to test whether he had really flattened all the sharp places.

Because human skin is the most fragile, if there is no friction and roundness, rubbing it so hard will definitely bleed immediately.

You must know that their pressure on this rope may be four or five hundred catties, and as long as there is still a little sharpness, even if it is just a small burr, it is enough to slowly cut the whole rope.

Zhang Meng passed the rope through the groove, and then tied a few dead knots to make sure that it was stable enough, and then he breathed a sigh of relief.

"That's it, pull me up!"

Zhang Meng shouted loudly.

"Damn, it's been almost two hours, your kid's efficiency is really slow......"

The fat man almost fell asleep waiting, and he felt dizzy at the thought of how many more places would take the same amount of time.

"I didn't have much experience for the first time, so I can't help it!"

Zhang Meng said angrily, he was almost tired and out of breath.

"How many ropes do you have to wear?" Lady Na stared at Zhang Meng and asked.

"I'll think about it."

Zhang Meng calculated, these ropes hanging horizontally, they were hung vertically from the middle, and the weight they carried was likely to be more than four times!

"You need at least four pieces of hemp rope, and then remember that when you tie the hemp rope, you need to chisel out a smooth groove and smooth out all the sharp surfaces inside, and there must be no trace of mismatch."

Zhang Meng thought about it and told Lady Na about those precautions.

"I'll do it again, and you can sort out the ropes."

Lady said, then tied the rope and slid down.

For a whole day, there were only eight places on the four ropes, and they were so busy that they almost went crazy.

And there is no day and night here, this state makes them feel even more uncomfortable, but fortunately, when the fat man went to search before, he brought back a lot of glowing tools, so they didn't have to work in the dark.

"That's it!"

After nearly twenty hours, the four ropes were completely buckled, and Gao Jin climbed back from one end of the rope, nodded at Zhang Meng, and signaled that everything was OK. Then, they just need to slowly lower the rope from here, and in one qiē they are done.

Zhang Meng is really a little proud, this idea was come up by himself, if it can really succeed, then this will definitely become something he will brag about for the rest of his life.

"Don't get too excited, we're just the beginning of a problem."

Lady coldly poured a basin of cold water on everyone.

"How deep this crack is, so far we don't have an accurate number. Have you ever wondered what would happen if the rope was all out and we still hadn't reached the bottom? And what if you encounter danger along the way, have you forgotten those screams? ”

Lady Na Lian said several questions, and suddenly pulled Zhang Meng and them back to reality from heaven at once.

"Fatty, how many meters can the rope go down?"

Zhang Meng asked with a frown.

"It should be possible to put a hundred and fifty meters, we have searched back and forth many times, and it is not very realistic to find some more ropes......

The fat man shook his head and said, they had gone back and searched again, and they had already tried their best to drag back all the materials that could be used. The rest are either the ones that are hard to find, or the ones that are too bulky to find some ropes.

"Actually, the probability of surviving is much more now, what is not satisfied, isn't it?"

Xiao Lou said softly, compared to before, they can now go down at least one hundred and fifty meters safely, and now their survival probability can be said to have increased to about fifty percent all of a sudden, which is already very good.

Zhang Meng nodded, he could only say that he had done his best, and then he could only look at the destiny of heaven, hoping that God would leave them a way to live.

They rested on the spot for a few hours, and then everyone ate a few more compressed biscuits and brought some dry food with them to make sure they didn't have any fitness problems, and they were ready to go.

"Which one comes first?"

Lady asked.

The atmosphere was somewhat quiet, and the first person was perhaps the most dangerous. And he also has to empty dangerous rocks along the way, so the body cost should be the largest among the people, so everyone will have some calculations in their hearts.

"I'll come, if I die, it will be to repay Zhang Meng's little brother for saving his life."

Gao Jin stood up and said, he took a deep breath and straddled the weapon on his back, and then Zhang Meng and they tied him with a rope, and then Gao Jin climbed into the middle of the crack, sat on the stool, and made a ready gesture towards Zhang Meng and them.

"Hold on!"

Zhang Meng shouted loudly, everyone worked together, and now they can only rely on everyone to slowly lower the rope, this is definitely a body job.

After about 20 meters, I heard an extremely dull sound from below.

"Stop!"

Everyone looked down, and now Gao Jin had landed around several intertwined rocks, he steadied himself, and then took out his hammer and struck on it.

Luckily they had a three-edged chisel, and they could use it as a nail to knock through the inside of the rocks little by little, otherwise a hammer would have been useless for hours.

Gao Jin's body was not bad, but it only took about forty minutes to chisel off a few stones that were stuck in the falling position, and let them fall.

"Keep put!"

Gao Jin's somewhat vague voice came from below, Zhang Meng's heart gradually lifted, and a little further, they completely lost Gao Jin's vision, and the voice is estimated to become more and more blurred when it comes here, and then they can only rely on Gao Jin himself.
