"Can we try firing the claws at the hole on the other side and then pull into a rope bridge and climb over it?" Sun Er suggested.

"Nope." Cao Longxuan directly rejected his suggestion.

"The entrance to the cave on the opposite side is full of stone walls that cannot be fixed. And this balance is constantly running, and the power is endless, even if you can get lucky enough to build a fixed place and pull it into a rope bridge, it will be interrupted by it. ”

"Although the bottom of this pit is deep, and there are spikes, if the people can go down the rope to the spikes, and spread the feet on the spikes, spread them on the opposite side, and hang the turning scales with the ropes, they should be able to climb up." That thirteen was also on the side to help with ideas.

Old Ghost Su grinned:

"Oh, you baby, you think so beautifully, what do you use to shop? Besides, how can you tie a rope to the scales at the bottom of such a deep pit?

Even if you can tie it, when you pull the rope and climb up, you don't know where it has turned.

Besides, a single pallet hanging rope, there is no balance on the other side, and you still want to go up to a ball? ”

Thirteen was choked by Old Ghost Su and blushed, and after thinking for a long time, he said, "Everyone can climb up and tie the rope first..."

"Pull it down, brother, I see that you are pulling a calf, if you can climb up, you might as well just turn around like a bus, and you still have to work so hard to tie a rope and something, isn't that a clean and tidy thing that is not needed?" Niu Gang said bluntly again.

Thirteen scratched his ears and said no more.

"Actually, as Thirteen said, there are some possibilities." Cao Longxuan stared at the long-rotating balance in front of him and said slowly.

"You mean to climb up and hang the rope first?" Old Ghost Su obviously didn't think this method was feasible, and shook his head as he asked.

"Climb up, it's impossible." His words undoubtedly made everyone's mood a little heavier, after all, he was a recognized "expert" in this group of people, and even if he made up his mind, it meant that another possible road was ruthlessly blocked.

"Don't climb up." Cao Longxuan seemed to have made a decision in his heart. "Tie the tray."

Hearing Cao Longxuan say this, Bai Yunfei suddenly had an inspiration in his heart: "Boss Cao, you mean to tie the tray?" Don't... Do you want to use this pallet to ferry people over? ”

Cao Longxuan showed his trademark smile again:

"It should be so, if the guess is correct, if this balance is not used by the ferryman, then why is it used? Putting on how to ferry, of course, is to put people on pallets. Isn't this true even for ordinary cargo balances? But I don't know, Yunfei, what do you think? ”

"Of course it's normal for people to be on a tray, but this rope... Wrong! ”

Bai Yunfei was about to say that according to his thoughts, Bai Yunfei might guess what he was doing, when suddenly a signal crossed his mind.

Yes, it was a fleeting signal, Bai Yunfei suddenly remembered something.

Bai Yunfei frowned and pondered for a moment, then turned his back to the giant pit and looked at the stone walls on both sides of the passage.

"Look!" Bai Yunfei couldn't suppress his excitement, shouted to them loudly, and pointed to the stone wall that was now on his right: "What is that?" ”

It turned out that Bai Yunfei suddenly remembered that when he was about to climb to the bottom of the pit just now, and wanted to explore the bottom of the pit to find an exit and passage, a poisonous snake appeared.

Then, when he struggled to escape from the edge of the pit, he seemed to find a black shadow on the stone wall at the mouth of the passage here, but he didn't know what it was.

Just now, everyone walked from the passage, and after walking to the entrance of the passage, they kept facing the huge pit in front of them, and were shocked by this huge pit.

Therefore, everyone's attention is all on the giant pit in front of them, and they have been facing the research ahead without paying attention to the left and right.

The contact between this passage mouth and the entire "bucket" shaped pit and the dome that seems to be "buckled" on it is not directly bent according to the arc of the "bucket", but the passage mouth is built with a stone to the back.

This makes a less obvious depression form in the direction of the deep pit, and because of the angle, the light of the glow stick at the bottom of the pit basically can't shine here, so the light here is a little dark.

And in this dim depression, there is a piece of oil shale that is the same color as the scale.

When everyone saw this black thing, they quickly moved all the flashlights over, and immediately found that it was a stone stele.

I saw that there were four big characters engraved on the stele, and the words were engraved with the dragon flying and the phoenix dancing, and the pen walked the dragon and snake, and the end was strong and powerful.

In the face of this written word, although I think that this word is written extraordinary, no one can understand what is written.

"Torture the scales." Only Cao Longxuan recognized it, and he said that it was a big seal, a kind of seal character system.

"What do you mean?" Everyone looked at each other.

This balance is so big, you still have to torture, what to torture, who do you want to torture?

Obviously, this is a test of the wisdom of the people, or something else.

In short, the owner of this tomb also knew that it was impossible to ensure that this tomb would be hidden for a long time after his death.

Even if it is discovered, it can't be so easy for the people who break into the tomb to pass, so it is necessary to test the comers. ”

Bai Yunfei said his guess while constantly moving the flashlight, shining the stone tablet all over the front, back, left and right, and examining it very carefully.

Then he moved the flashlight and carefully looked at the other side of the stone-built passageway.

"Ha, look! Look what's that?! Bai Yunfei shouted excitedly.

Everyone took their eyes away from the stone tablet of "Torture Balance", gathered at the location where Bai Yunfei's flashlight was illuminated, and gathered over.

It turned out that here on the other side of the passage, there was also a stone monument in the depression on this side.

However, the material of this stele is different from the previous stele in that it is not carved from oil shale, but from granite strips of stone that form a passage.

I saw that this stone tablet was engraved with dense words, and the words on it could still be recognized by everyone.

Although these characters are traditional characters, some of them are also very obscure and obscure, but after all, they are stronger than the general seal of the book that day, and after reading the whole text, you can actually understand a rough idea.

It turned out that this text was left by the statue in the cave of the scriptures, Hong Bian.

The inscription mainly tells about his life and how he discovered the seventeenth cave and used it as a shadow hall after his death.

Hong Wei is a monk in Dunhuang.

The common surname is Wu, also known as Wu Monk and Wu Sengtong, his father's name is Xuzhi, and his mother is Nanyang Zhang.

Wu Hongbi was a monk when he was young, and he was very eloquent, proficient in the Tibetan language, translating Buddhist scriptures, and studying only knowledge.

He has served as an associate professor of law and photography in Shimendu, Shazhou, Dafan for more than ten years.

In the second year of Dazhong (848), the national hero Zhang Yichao raised troops in Dunhuang and overthrew the rule of Tubo in Hexi.

At the right time, Wu Hongbi raised his arms with the prestige and status of the supreme leader of the Sangha in Hexi, and the monks and soldiers swarmed up under his inspiration, and cooperated with Zhang Yichao's righteous army to crusade against Tibet, and made great contributions.

He mentioned in the inscription that in his subconscious life as a Buddha, he was never confused by the glitz, and for thirty years, he practiced quietly and vigorously propagated the Dharma.

Under his leadership and auspices, Dunhuang has been translating the scriptures endlessly, preaching the scriptures continuously, the Dharma meetings are frequent, and the caves have not stopped.

During this period, Hong Biao presided over the excavation of another large Buddha cave, that is, the sixteenth cave of the Mogao Caves in Dunhuang (also known as the Wu Seng Tong Cave in later generations, of course, there is no such record on the inscription).

And in the process of excavating the sixteenth cave, a secret room that existed before was found on the north wall of the road, and there was a secret passage to communicate.

So Hong Wei led people into the secret passage many times to study the truth.

However, after passing through many organs and messages, and losing several people, when it came to the "torture scale", it could no longer pass, and until death, he could not solve the mystery of where this passage leads.

At that time, it was a war, and there was not much time to study this mysterious underground passage.

And because of the secret of this passage, some monks and believers have been damaged, and they planned to go out to rest first, and continue to gather people to continue to explore one day.

However, the perennial war is chaotic, and it is necessary to deal with the war at any time, and it is rare to have peace for a while, so it runs aground.

In the later period, although there was a little tranquility in the Hexi area, Hong Wei was already old and decrepit, and he was overwhelmed with all kinds of miscellaneous things, which was quite energy-consuming.

And Hong Wei decided to use the spare time of his later years to be a Buddha and not ask about other things.

Then the passage that has not yet solved the mystery is ordered to be closed, so that people who are curious or greedy will not have any plans and cause further disasters.

Later, he sent someone to build a meditation room, and devoted himself to practicing meditation and enlightenment here.

Later, before he was about to die, he felt that time was running out, so he asked the people to change this meditation room into his shadow hall, and specially asked people to erect this monument here to warn the people who intruded in the future.

Later, he blocked the passage at the shadow hall, and ordered someone to erect a memorial monument after his death, so as to close the secret passage as a barrier.

After Hong Bian's death, in order to avoid the war, the monks of later generations were afraid that the scriptures and classics at that time would be persecuted by the war, so they piled up a large number of them in Hong Bian's shadow hall, and moved out his statues and monuments.

As for his coffin, it must have been impossible to tell where it went.

However, this has been many years after his death, and there will definitely be no reflection on the monument.

It turns out that this is the seventeenth cave of the Mogao Grottoes in Dunhuang, which is the origin of the world-famous Tibetan scripture cave, but I didn't expect that there are still these twists and turns here.

Judging from the inscription, this Hong Wei and his followers did not find out the true inside story of this mysterious passage until their deaths.

"It seems that this is really difficult." After reading the inscription that Hong Wei erected here, Cao Longxuan pondered for a long time, and finally expressed his opinion.

"There's really a danger ahead. The front drips are all familiar roads, and the back is the raw pit. Old Ghost Su muttered.

Cao Longxuan turned around with interest, looked at Bai Yunfei and said:

"Yunfei, you are really careful and thoughtful, and you have discovered such an easily overlooked detail, very good, very good! Ha ha. Tell us what you think. ”

Bai Yunfei never understood why this Cao Longxuan was always "the same person" when he spoke, was it to establish his image as a king, and to give people a sense of "tall, big, and up" in his speech?

Or is he disguised as a modern person, but in fact he has traveled from ancient times, and it is difficult to change the habit of speaking of the ancients?

You must know that a person's accent and living habits can be slowly changed, and the only thing that is difficult to change is dialect and speaking habits.

But this thought flashed in Bai Yunfei's heart.

Cao Longxuan asked him to talk about his opinion, referring to the matter of tying the rope to the tray.

Before guiding everyone to look at the stone stele, Bai Yunfei had already vaguely guessed his thoughts.

So Bai Yunfei coughed dryly and cleared his throat: "Boss Cao, I guess you may want to tie a piece of rope to one of the trays first, the length is about the height that the tray can rise after the other end of the tray is put with a heavy object, and there is no weight here but the end of the rope is tied." Am I right? ”

Cao Longxuan smiled again and stretched out a thumbs up to Bai Yunfei: "Sure enough, it's a talent!" ”

When Bai Yunfei received an affirmative answer, he knew even more in his heart, so he continued: "Then how to solve the balance problem between the heavy object used for the first time and the person who was the first to get on the pallet?" ”

"It's a real problem, and it's up to the person." Cao Longxuan thought and said.

Listening to what he said, Bai Yunfei had an idea in his heart, this method is not bad, but the weight of a person is fixed, but where to find an object of the same weight as this person?

Bai Yunfei said his thoughts, but he didn't expect Sun Er to come up with an idea: "Master Long, look, the backpacks on this family are heavy objects, and they are also very heavy, just use a few backpacks." ”

"But how can the weight be guaranteed to be the same as that person?" Bai Yunfei asked.

Sun Er scratched his head and said:

"You can use Mr. Su's shovel handle as a lever, Mr. Su's shovel handle is very strong, we can borrow it."

And they were to use one man to carry the 'weighing' that had been changed from the handle of the shovel in the middle, and to hang a man at one end and a heavy object at the other.

When the two ends are balanced, it proves that the weight is the same. ”

Not to mention, the method that Sun Er thought of was still good.

I saw Cao Longxuan patting him on the shoulder heavily and complimenting: "Yes, second son, there is progress." ”

was praised by the boss, and Sun Er was excited.

So everyone tied the rucksack to the Luoyang shovel handle with a rope according to what Sun Er said, needless to say, this rucksack is the "weighing stone".

As for the question of who will carry the shovel handle, everyone unanimously turned their attention to Niu Gang.

And after the big black bull saw everyone's eyes, he muttered a little angrily: "Hmph, I knew it would be me." ”

In the laughter of everyone, he straightened his stout body, grasped the middle position of the shovel handle, carried the shovel handle, and began to act as the support of the "weighing rod".

As for the question of who to choose as the first "goods", naturally there is no need to study, but as soon as Sun Er gave an order, the thirteen came out of the crowd, grabbed the other end of the shovel handle with both hands, curled up his legs, and hung up.

Sun Er hurriedly hung a rucksack at the other end of the "weighing rod" and held it with his hand to prevent "overturning".

Everyone began to busily unload their backpacks and line up beside the stone wall on the side of the passage.

Then add or subtract items to the rucksack that hangs at the other end of the "weighing rod" in anticipation of a weight balance.
