mentioned Shen Yifan last time; ghost doctor Yu Mengcheng; The two brothers, Hongwen and Hongwu, found the way to enter the tomb of Zhang Wenchuan, the master of the Xichuan Kingdom, but what they didn't expect was that what they entered was actually a very complicated Soul Ladder, and everyone spent a long time on the Soul Ladder before they knew that they had stepped on the Soul Ladder.

The stupidest and most effective method they use is to find the exit layer by layer.

Originating from the Western Zhou Dynasty, the Hanging Soul Ladder is a labyrinthine ancient anti-tomb robbery method, which uses the fixed thinking paralysis of the human brain and the dim dimness of the surrounding light to confuse those who rob the tomb.

The four of them worked in pairs, one up and one down, all the way to the end, and at the middle staircase of the second circular marker, the four met and found a passage on the left and right that could only allow one person to enter sideways.

According to Shen Yifan's speculation on the Soul Ladder in front of him, it should be a five-set Soul Ladder, and the Soul Ladder of this scale is already relatively large, Shen Yifan speculated that the Soul Ladder they are now in should be the most middle, that is to say, whether it is left or entered, or the Soul Ladder, if the four of them find the two passages found here, it will prove that these are the only two passages.

Hong Wen Hongwu meant to enter in two teams separately, and was immediately vetoed by Shen Yifan.

Shen Yifan said: "I guess this Soul Ladder is five sets of ladders for the time being, but it cannot be ruled out that it may be the largest Soul Ladder, if so, it may be dangerous for our personnel to disperse." ”

Shen Yifan also said something he had heard, he had heard in Liangxi Nanyuan that there was a team of explorers who had entered Badain Jarin to find the lost ancient city, and they stayed in a devil's city before entering Badain Jarin, but after entering the devil's city, they found that they were trapped by the intricate roads inside, and then the leader realized that he had entered the same maze as the soul ladder, and after walking in it for three days and three nights, he still relied on a master in the team to use the blue and white snake to find a way out, Later, they learned that this labyrinth was deliberately built according to the drawings of the eight sets of soul ladders in the soul ladder, and if it wasn't for the help of strange people in the team, they would not be able to get out of the maze in their lives.

Shen Yifan said: "So we can't underestimate the Soul Ladder in front of us, I think it's marked here, let's use the old way to go all the way!" ”

Everyone listens to it quite reasonably, just follow Shen Yifan's method, although this method is stupid and timeless, but it is the safest method.

Just as they were about to enter the passage on the left, they heard a wail overhead, followed by the sound of chains turning and rubbing overhead. Everyone immediately understood that perhaps Zhang Wenchuan's suspicious grave above had been touched by other organs.

Shen Yifan looked up at the ceiling above his head, and was also surprised by the ingenuity of this tomb, it turned out that above them was where the machinery of the hidden weapon was located.

It seems that Zhang Wenchuan divided his tomb into two, the doubtful tomb is on the top and the real tomb is below, and the middle is the organ layer, so that no matter whether the top tomb or the real tomb below is the most suitable place for the layout of the organ. But at this time, he didn't have much to distract, and his current task was to get out of the Soul Ladder.

After the four of them entered, it was still a soul ladder, and they walked again according to the previous method, this time they found three exits, two on the right and one on the left, except for the passage they came in before, it was still two, but this time the location of the three passages was not on the same step, according to Shen Yifan's speculation, they still entered from the leftmost passage.

After entering, it was the old way, and this time something strange happened, that is, there were five passages on this soul ladder, three on the left and two on the right, which made Shen Yifan a little puzzled. According to Shen Yifan's speculation, the last Soul Hanging Ladder on the left either has no passage, or only one passage, if there are three passages on the left, it can explain that there may be more than five sets of ladders for this Soul Hanging Ladder.

The ghost doctor asked, "Shall we continue walking?" ”

Shen Yifan gritted his teeth and said, "Go!" I don't believe I can't get out of this soul ladder. ”

Hong Wen interjected a sentence on the side: "It is said that people who are keen on the Soul Ladder are basically obsessed with mathematics, do you think this is related to mathematics?" ”

The ghost doctor joked on the side, "You mean, this may be a math problem." Q: A total of eight Soul Ladders now have ABCD...... X and other several exits, Xiao Ming walked three exits and several exits, where are the exits of the first Hanging Soul Ladder? ”

Shen Yifan was almost amused by the ghost doctor's joke when he heard this, he thought for a moment and said, "I guess there is another possibility, but I have to go through all the soul ladders on the left to determine whether my guess is true." ”

The four of them rested for a while and then headed towards the left passage again, they casually walked through one of the three passages, but after walking several passages in a row, they found that the four of them had been completely lost in this large set of soul ladders.

Judging from the situation that has come down during this time, Shen Yifan has already concluded that his previous guess may be valid. They are in a soul ladder with eight sets of ladders that have been improved again, which is also very in line with the technology of the Ming Dynasty.

Shen Yifan sat on the steps and drew on it with paper and said, "We guessed at first that it was a five-set soul ladder, but now it seems that it is not at all. However, there are only eight sets of soul ladders at most. As he spoke, he drew all the guesses from one set of ladders to five sets of ladders on the paper, leaving six sets of ladders; Seven sets of ladders and eight sets of ladders, three guesses.

Then Shen Yifan drew a sketch in the six sets of ladders, which was represented by six Arabic numerals "8", and then connected the six "8" symbols with a zigzag line, and said to himself: "Is this so?" ”

The ghost doctor asked curiously, "What's the matter?" ”

Shen Yifan handed the sketch he drew to the ghost doctor, and after reading it, the ghost doctor said, "It's possible." We may think of this ladder as too complicated. ”

Hong Wen Hongwu asked on the side, "What do you mean?" ”

Shen Yifan said: "Actually, we thought about this matter from the beginning. No matter how many sets of Soul Ladders there are, the entrance and exit of the dead are also one, no matter how many passages the Soul Ladder is connected later, in fact, we just need to follow a true exit of the Soul Ladder. ”

Hong Wen and Hong Wu listened a little twisted, and looked at Shen Yifan with a confused expression, because they thought that Shen Yifan was an old Qitong Tianyan and it was not easy to attack, so they said weakly: "Is there no difference between what you said and what you didn't say?" Where are we importing and exporting? ”

The ghost doctor said, "Before I entered the Soul Ladder, I placed a red glow stick at the entrance. We just need to find the right entrance to find the exit. ”

The two twins of Hongwen and Hongwu suddenly made the same expression, and said in unison: "It's so simple? ”

Shen Yifan said: "A great scientist once said that man is an animal who likes to complicate simple affairs. ”

I don't know which great scientist said this, but sometimes it's the same when we look closely, and emotionally speaking, sometimes we say something particularly rude for our own selfish desires as if we were taking social responsibility. It's like us humans eating, sometimes very simple apples can be eaten raw, and we have to make a shredded apple or something. In other words, human beings are actually people who like to complicate simple things.

The four of them returned to the first soul ladder and found the entrance they had originally entered, and there were really one or two red glow sticks that shimmered on one side of the entrance, and when they arrived here, they could hear a burst of knocking sound from above, and it was estimated that Xia Ying and others were still carrying out rescue when they touched the mechanism.

Shen Yifan was a little curious, and asked Hong Wen Hongwu: "Aren't you worried about the senior brothers?" ”

Hong Wu smiled mysteriously and said, "Actually, this is also part of our plan. Lu Meng deliberately touched the mechanism and delayed them as long as possible. ”

Shen Yifan said: "It's actually very simple to get out of this soul ladder. You remember that there is a mark on every eighteen steps of this ladder, but in fact this is to confuse us, let's ignore the mark, and turn right every fifteen steps, regardless of whether there is a wall or not. ”

The Hong brothers couldn't believe it, and looked at Shen Yifan and wanted to ask something? But I still feel that something is wrong.

Shen Yifan said: "In fact, the Soul Ladder is indeed related to mathematics, but it has nothing to do with the so-called application problems. It has a lot to do with geometry. ”

The Soul Ladder they are in is a huge Soul Ladder, but in some cases, the huge project does not mean how complicated the project is, the Great Wall is one of the largest projects in the world! But its function is actually very simple, it is a wall against foreign enemies.

Hong Wen and Hongwu didn't quite believe Shen Yifan's statement, but now there was no other way but to try, and the two of them took the lead and walked down, counting as they went. When they got to the fifteenth order, they all looked to the right.

Hong Wen shouted and said, "How can there be a passage!" It's a wall. ”

Shen Yifan walked to their side, touched it with his hand, and then the whole person looked sideways at the wall, and the strange thing was that Shen Yifan suddenly disappeared in front of the two of them, and then magically leaned out half of his body and waved at them.

This time, everyone suddenly realized, it turned out that they had been confused by two things on the Soul Ladder, the first was the circular sign of every eighteen steps, and the other was the so-called passages, if they followed the original method, they would not want to get out of this Soul Ladder for the rest of their lives.

There is a small hidden passage on the fifteenth step of each Soul Ladder, and because the Soul Ladder is oiled all around with a paint that absorbs light sources, they have a very small field of vision, so it's easy to overlook subtle things.

Mastering this method, everyone will soon be able to find the exit from the Soul Ladder, and after going out, they all exclaim that it is not easy, it turns out that sometimes it is not the weird hidden weapon that defeats them, but themselves.

In fact, although the layout of the Soul Ladder is complex and ingenious, when the Soul Ladder first appeared, it was a tool for recreation, so it was impossible to join the road out, and it was impossible to build an exit when the Soul Ladder was built, but the tomb owner would be buried here by descendants after his death, so in some cases, the entrance and exit could only be arranged simply, so the entrance and exit of Shen Yifan and others were at the intersection of the number '8'.

After the four of them left the soul ladder, they saw that in front of them was a burial chamber, the burial chamber was not very large, but the burial chamber was full of funerary goods, and these burial goods were not gold, silver and jade silks, but piles of bamboo slips; Ancient books and the like.

There is a coffin in the middle of the tomb, the coffin is intact and has not been opened again, but there are a lot of bamboo slips and silk silk things scattered on the side of the coffin, and there are many written contents recorded on those silk silks.

Shen Yifan looked at some bamboo slips scattered on the ground and said, "These bamboo slips seem to be about an air vehicle, could they be the round boat mentioned in Beidou City?" ”

Hong Wen asked, "Do you want to open the coffin?" ”

Shen Yifan looked through some bamboo slips and said, "The things recorded here are very complicated. Some are unheard of. Someone should have come in to look at the environment, but where did they come from? ”

The ghost doctor patted Shen Yifan and pointed to the top of the tomb, Shen Yifan found that there was actually a square place on the top of the tomb that was paved with modern ordinary red bricks, looking at the red brick, Shen Yifan and the ghost doctor already understood that a group of people who came before all went out from the top, and a master directly calculated a thief hole and hit it on the top of Zhang Wenchuan's real tomb.

Shen Yifan was a little ashamed to see it, he knew at a glance that this thief hole must be the so-called two brothers Dong Wenxuan and Dong Wenshuo, in addition to these two brothers, Yifan went down directly to the vault of the main tomb with an accurate shovel. And after they went out, they actually sealed this thief hole.

The ghost doctor said with a smile: "Only these two brothers are so particular about doing things. ”

Hong Wen Hongwu asked again: "Do you want to open the coffin?" ”

Shen Yifan nodded and said, "Open the coffin." ”

Although Hongwen Hongwu is the senior brother of Tongtian Eye, he naturally cannot compare with Tongtian Eye in terms of tomb robbery technology, so Hongwen Hongwu needs to seek the opinions of Shen Yifan and the ghost doctor.

Since Shen Yifan opened his mouth to open the coffin, Hong Wen Hongwu began to work hard, and it didn't take long to see that Hong Wen Hongwu had already tied a bundle of rope to tie the coffin lid firmly.

This method is also peculiar, and it is one of the ways to open a coffin when there are few people. Because the coffins in the ancient tombs are all made of stone, it is rare that the coffins that are not made of stone are also four bronze and the like, which is very heavy. When there are few people, some people put the coffin lid on the coffin, and then use the oil hyacinth to open the coffin directly.

I saw Hong Wen Hongwu tie the coffin lid, and then took out a section of aluminum alloy tubes from the bag, and later the ghost doctor told Shen Yifan that this is a kind of nanotechnology tube, which can withstand fifty meals, but its weight is very light, and it doesn't feel like anything when it is carried on the body.

The two brothers connected the pipe into a shelf and placed it directly next to the coffin, put the rope on the oil gourd on the shelf, and then the brothers gently pulled it up.

When the coffin was opened, there was no corpse inside, only a notebook with a cowhide cover, which looked like a modern object.

Shen Yifan took out the notebook, put it in his hand and looked back and forth. This is an archaeological notebook used by archaeologists, and it also contains many photographs, some of which are old and yellowed, and the thick notes are tied with a cowhide band.

Shen Yifan opened the notebook and saw that a lot of content was recorded in thin gold font, Hong Wen came over and looked at it and said in surprise: "It's the master's handwriting." ”

Shen Yifan was also calm, and said with a fake look: "I know." I'm looking at the content. ”

The handwriting on this notebook was different from the one Lu Meng received, and Shen Yifan realized that the two notebooks should have been written by Dong Wenxuan and Dong Wenshuo respectively.

The first notebook Shen Yifan has read, the content is roughly around the things around the Kushan Mountain in Yubei, which mentions about the Yuanzhou, and the notes mentioned that the Kushan in Yubei where the Dong brothers arrived first also found the tomb of the Xichuan Kingdom Division, the key is the five locations on the map, Shen Yifan thinks that the Dong brothers will go to these five locations one after another.

The second notebook is the notebook that Shen Yifan and others got in the tomb of the Xichuan Kingdom, Shen Yifan took a cursory look, and the content in it was roughly around the Taiping Heavenly Kingdom, which mentioned Xiao Chaogui and Wing King Shi Dakai, one of which made Shen Yifan attach great importance to it, it was mentioned that Shi Dakai had secretly come to Kushan in northern Chongqing, which was still under the jurisdiction of the Qing court at that time, and why did he come secretly.

Shen Yifan and the others have completed all the searches for the mausoleum of Zhang Wenchuan, the master of the Xichuan Kingdom, they went up from the vault of the tomb, uncovered all the red bricks, entered the old robbery holes, and left the tomb smoothly from the robbery holes.

Regarding the content of the notes they got, Shen Yifan was very curious, because it mentioned Beidou City and Jinling. He guessed that the starting point of the Dong brothers should be the Kushan Mountain in Yubei, and Beidou City may not have been there.

After leaving the tomb of the Xichuan Kingdom Master, what did Shen Yifan find in the two notebooks? And what is the next plan for him and the seven sons of Guigu? Why did Yubei's behavior prompt Shen Yifan to go to Guwu Town in the south of the Yangtze River?
