Bai Yunfei suddenly thought of a problem, so he quickly started the mysterious computer in his mind, and after some calculations, he immediately stopped everyone.

Bai Yunfei pointed to the opposite side and said:

"You can't do this method, in this case, you can only pass one person, and the follow-up people will definitely not be able to pass.

Even if the latter people do it according to the methods of the first person, there will be a lot of risks, and the passage of the last person and material will be a problem.

Moreover, by increasing or decreasing the amount of material in the backpack, it is not only troublesome to match each person who has to pass through, but also the people have to transport not only the people there, but also the materials to be transported over.

If you keep it like this, the last time, there will be a lot of supplies in your backpack and abandoned on the scales. ”

Everyone thought about his words carefully, and some people had already understood what Bai Yunfei meant, so they asked Bai Yunfei how to solve this problem?

Of course, there were a few people who didn't understand, so he could explain it more clearly.

Bai Yunfei patiently told everyone that in this special environment surrounded by poisonous snakes, using the balance to reach the opposite passage through the giant pit is already the only way at present.

But even if the first person passes, what happens to the people who follow?

Of course, you can take the rucksack off like the first person, measure the weight of the second person, and then tie the rucksack and the second person back on.

But in this case, the trouble is a trivial matter, the key is to continue this cycle, what to do with the last person?

By the time I laboriously pulled down the rope that hung over the tray at a high place, the tray had essentially turned away.

In the case of no help, it is still unknown whether it can go up quickly, and even if it can go up, the weight and the rucksack of the second-to-last person will definitely be inconsistent, and it will be heavier.

Everyone knows what kind of danger there will be if they are too heavy.

Moreover, what is the use of the light people in the past, everyone's equipment, materials, and tools need to be transported over, and the materials will not pass by transporting people first.

Even if the supplies are transported first, what happens to the last rucksack after the last person jumps from the pallet to the opposite aisle?

Those who didn't understand it, listening to Bai Yunfei's detailed explanation, basically understood, but they were all stunned because of this.

Even if his scheming is as deep as Cao Longxuan, he is also confused.

They seemed to be confused by Bai Yunfei's words like tongue twisters, and it was estimated that now they used their brains to imagine what Bai Yunfei said just now, it must be a little chaotic.

"As you say, what should I do?" Cao Longxuan looked at Bai Yunfei, his gaze becoming even deeper in the dim cave.

Bai Yunfei didn't think about it, because he had already straightened out his thoughts very clearly, and immediately replied:

"If you want people and supplies to get through, you have to have at least three key points:

First, it is necessary to make some standard weights and fix the weight of these weights, and not solve the problem by adding or subtracting materials in the backpack at will.

Not only will this be troublesome, but there will also be backpacks and supplies that will end up being abandoned on the scales.

In other words, people, as well as the rucksack, are all 'goods', and they cannot be used as weights, and the weights must be made separately, so as to ensure that all people and the rucksack can pass safely and smoothly to the opposite side.

The second is that the first person to pass is very important, and this first person to pass is not only a 'water tester', but also has to take great risks to explore the way, and may become a victim.

And after being able to pass successfully, it is necessary to skillfully cooperate with the operation on the opposite side, which will play a very key role in the early stage.

The third is that it is more difficult to deal with the last person, but with reasonable methods and calculations, the problem is not too big, and only the last person who passes is bold, careful, and has a good psychological quality, and does not panic.

Because when he was left alone on this side, there was no one on this side to assist and help him, he had to have a clear understanding of this method, and at the same time act quickly and decisively.

Moreover, we should also pay attention to a detail, every time we transport a person or material to the opposite side, the people on this side of the passage we are now on must pay attention to the moment when the person or thing on the opposite side comes down.

Because at this moment, the force of the person's kicking and the subsequent detachment, or the movement of materials, will change the original balance.

It doesn't matter if the shaking is small due to the change, but if it is too large, it may cause the weight we make to be lost, because the pallet may be tilted more severely.

However, this problem can be solved by tying weights with rope for a while, but it depends on how much the other side of the pallet is tilted when there is a weight on only one side.

If the angle between the connecting rod arm of the lifting tray and the pallet is too deformed, it is possible to twist the rope alive, and it is still possible to drop the weight.

In the same way, every time you put materials or people on the other side, the person who passed by first on the opposite side should also observe and cooperate well, apply a balance force on the opposite side, and try to ensure that the trays on both sides are still balanced and parallel, without too much fluctuation up and down.

Otherwise, the people here will fluctuate too much, and it will not be such a trivial matter as losing weights, and there are so many poisonous snakes 'waiting' for us in this circle of sulfur belts. ”

"Where do you find something to make weights? We go back outside, we get out of the spot, we go back to the city, we make some weights according to everyone's weight, and then we sneak back? That's not realistic. Thirteen had an incredulous look on his face.

"Haha, if my method is so stupid, it will hurt everyone.

Even if everyone can enter and exit unhindered without being detected, how can a weight be made to be as big as a person's weight?

The crowd didn't have to carry anything else, and the weight alone made everyone tired.

Of course, there are large and small weights, which can be accumulated or decreased.

And we don't have to go back to the trouble of turning back, we can use local materials. ”

Bai Yunfei explained confidently.

Or is Cao Longxuan smart, he glanced around, and his eyes lit up: "Oh? Do you want to... With these strip stones? ”

"Yes!"

Bai Yunfei knocked on the stone passage beside him with the end of the flashlight grip, and said confidently:

"These stones, with regular shapes, the same volume, and the same material, are basically the same weight for each piece.

Let's take a few complete stones, measure them according to the average weight of adults, find a rough average, and adjust the rest by those small weights, which can basically match everyone's weight.

Let's divide a whole piece of stone evenly into several small pieces, so that everyone has a weight that can be increased or decreased at will, but the weight can be accurately controlled. ”

"Oh mom, Bai squad leader, what's the melon seed in your head? Why didn't you notice that you still had these two brushes when you were in the army? However, according to your order, this passage will not collapse and bury everyone inside, right? Niu Gang asked excitedly and worriedly.

"No, big bull." Bai Yunfei continued:

"Just now, we smashed and pried off the big stone slabs of the three roofs on the rolling stone slope, and they did not collapse, which shows that the overall load-bearing capacity of this passage is very good.

And these strips of stone are supported on the side, such a long stone wall, it doesn't matter how many pieces are removed.

Do you still remember the passage from Hong Bian's memorial monument to the passage between the 'Nine Absolute Connecting Gates'?

This section is simply not piled up with stones, it is still safe and firm, and thousands of years have passed, isn't there still no collapse and fragmentation?

Although it is estimated that there is a stone in this section, because there is a stone to support on the outside, the earthen wall inside is not as solid as the method of 'dry base'.

But I think this is mainly due to the need to form a mechanism and message area when it was originally designed, rather than to indicate that the soil here is looser and less stable than the previous section.

In short, in a word, I think it doesn't hurt to tear it down a few stones! ”

"Babble!" Old Ghost Su suddenly pounced, hugged Bai Yunfei's shoulders, and looked shy, almost sticking to Bai Yunfei's face: "Bai family baby, are you married?" ”

Bai Yunfei trembled with fright, although he didn't guess what the ultimate purpose of his question was, he still had an ominous premonition.

"You mean a daughter-in-law?" Bai Yunfei was a little unsure of his words, because this old guy not only spoke out of his mouth, making people unable to keep up with his train of thought, but he also always mixed in some dialect words that he didn't know where they were when he spoke, which was easy for you to confuse the meaning of this sentence.

"Right, right." Old Ghost Su's head nodded like a chicken pecking rice.

"Well, not yet, old Su, you... Why is this asked? Bai Yunfei was a little drumming in his heart, this old guy was chattering all day long, and he didn't want to discuss the topic just now, why did he suddenly jump to marrying a daughter-in-law?

This is too out-of-the-box, isn't it? But no matter how you guess, it doesn't look like something good.

Bai Yunfei subconsciously wanted to break out of his embrace.

"Hehe, I'm a distant relative, very delicate, I promised her to give you a baby. That awesome ass is round and earthy, and it will definitely give you more than ten big fat dolls. ”

The old ghost Su said in a matter-of-fact manner: "It's just a mile, you have to have a small condition, you have to worship my old ghost as a teacher, and learn this body technique from me." Do you want to get it? ”

"Get, get!" These damn guys took the opportunity to coax, and they had to ask Bai Yunfei to kowtow to Old Ghost Su now, and even have a confession with a teacher.

As soon as he heard this, Bai Yunfei was so shocked that his blood suddenly surged, and a mouthful of phlegm inadvertently surged up in his throat, stuck there, making Bai Yunfei short of breath and tight, almost suffocating.

Bai Yunfei said in his heart, I'm afraid of you old guy, don't hurt me.

Fortunately, Cao Longxuan began to gather everyone and start working according to Bai Yunfei's method, everyone had to do it, and this old ghost Su would not have time to entangle with Bai Yunfei.

It's easier said than done, and that's true.

Although Bai Yunfei seemed to be easy to say, he was still busy for more than an hour before he prying off a few complete pieces of stone from the stone wall.

The first piece does not need to be thought, it must be broken in the whole piece, and it is impossible to keep it intact, otherwise these stones will be put together with each other, and the first one will not be violently destroyed, and the next stone will not be able to be dismantled.

However, after the first piece is solved, the rest of the time is much less.

In the end, two strips of stone were dismantled and cut into small weights of equal weights, which was a bit difficult because there were no professional tools for cutting stones.

Only with a sledgehammer and an iron drill, on the stone with the equidistant cutting line drawn, first knock out a circle of shallow pits, then gradually connect into a trench, then dig deep, and finally pad on other stones to overhead, with a sledgehammer to smash it.

But after all, the tools used are temporary, and the time is also in a hurry, so although the distance between the dividing lines is uniform, it is not flat after smashing, there are concave and convex, so there must be a difference in the weight of each.

Fortunately, these small portions will not have too much impact on the overall use.

Ready to stop, everyone was ready to start tying a stone to a tray as Bai Yunfei said.

The reason why it is said to be "tied" is a prudent approach, after all, this balance is too weird, the first time, it must be a heavy object on one side, and no heavy object on the other side, it is difficult to ensure that after the balance on both sides is lost, there will be unexpected situations, so it is still tied to it with a rope.

But when everyone was about to quickly put a stone on the tray and tie it up, they were stopped by Bai Yunfei.

Everyone looked at Bai Yunfei in puzzlement.

Bai Yunfei said decisively: "No, we have to remove at least four pieces." ”

As I roughly estimated just now, each stone weighs about seventy or eighty pounds, and two pieces are exactly about the weight of an adult man.

Sun Er asked Bai Yunfei puzzled, saying that it was enough for a person's weight, and even the small weights that had been increased or decreased had been made, so what else was he dismantling?

At this time, Cao Longxuan replied to him instead of Bai Yunfei: "Yunfei is right, he should want the person who passed by for the first time to carry a stone weighing one person, right?" ”

Bai Yunfei nodded.

Everyone thought about it for a while, and they all reacted at once, and a few people stretched out a thumbs up to Bai Yunfei.

At this time, Bai Yunfei explained his thoughts to everyone in detail, and after confirming it repeatedly, he waited for everyone to nod their heads to show that they understood, and then started to act again.

First, four more stones were removed, and then it was time to "weigh." ”

The first is to use the shovel handle, first make the "human balance" just now, carry it in the middle by Niu Gang, hang a stone and a person on both sides, and measure the weight of each person respectively.

Everyone is basically the weight of two stones, which is nothing more than the difference between who has a few more small weights and who has a few less.

Then let everyone remember the number of weights that each person should add or subtract, so as to prevent the counterweight from making mistakes when passing one by one, which can have unimaginable consequences.

When one of the trays is turned in front of the crowd, they quickly tie the estimated length of rope to the boom of the tray and wait for it to continue spinning.

Before this tray was about to turn to the entrance of the passage opposite, the other one was about to come to the edge of the pit at the foot of the people.

Thirteen and Sun Er worked together to carry the four stones that had been tied together with ropes to prepare, while Bai Yunfei and Niu Gang were ready to hold the tray first.

As they quickly laid down the stones, the crowd carried the trays on both sides to prevent them from sinking before they were secured.

According to the division of labor studied in advance, because they were concentrated at the edge of the pit, the space was small, and Cao Longxuan and Su Lao Ghost needed to bend sideways and stand beside everyone.

While lifting the pallet at the same time, take into account the random guarantee to deal with any problems that may arise.
