When Professor Chen and the others returned to the waterhole, the water level had dropped by about half, and the stone statues below had already exposed their heads. After an hour of tossing and turning by Situ Fang and a few of them, the position adjustment of these stone statues was finally completed. At Situ Fang's insistence, he carried out the opening of the organ this time.

After the experience of yesterday's flood incident, in order to ensure safety, Zhang Gong asked Situ Fang to tie a rope to the stone statue in the middle to prevent yesterday's incident from happening again.

Everything was ready, and after Situ Fang pushed the two stone statues hard one by one, there was still a shock under his feet, and then the water in the cave instantly passed through the pool, rotating and flowing downward. After a few minutes, all the water in the cave was flowing down, but the level of the waterhole did not stop, but continued to swirl and descend rapidly. After more than three minutes, the water finally stopped flowing downward, and the water level dropped by about 15 meters from the plane just now.

After Situ Fang untied the rope fixed on his body, he took off his diving equipment, lay on the edge of the pool, leaned down to take a look, and then said to Professor Chen: "Professor, now the water level of the pool has dropped by more than ten meters, and the situation below is not clear from above, so I'll go down and take a look first." ”

"Okay, be careful!"

"Don't worry."

Situ Fang fixed the two ropes, used one of them as a safety rope, installed the protector, took the walkie-talkie handed over by Zhang Gong, and slid down slowly. Soon he discovered that there was a hole opposite the original hole, but it seemed to be dripping all the time.

After reporting this discovery to Professor Chen through the walkie-talkie, he entered the cave with permission.

It's pitch black here, and there's nothing to be found, and inside, like the other side, it's a stepless passage, and it's also upward.

In the on-call instructions, a few more climbing ropes were thrown from above, and soon, Professor Chen and the others came down. After looking at the structure of this gate, under the leadership of Situ Fang, the group slowly advanced towards the depths of the cave.

The same M-shaped passage, at the end of which the same stone statue appears, but inside it is no longer rotten wood: the walls on both sides are illuminated by flashlights, and the colorful frescoes are displayed in front of the eyes of several people. The middle is not empty, on a large wooden collapse, there are a few cases, behind this wooden collapse, there are two nine-branch lamps, and then behind, there are two bookshelves, on which are placed many bamboo slips.

Zheng Suo couldn't wait to walk to the mural and take a slow look. After reading the mural roughly, Professor Chen said to Zhang Gong: "Lao Zhang, if you look at the content of this mural, it is not a life story, but from this view, it looks like a big construction." ”

"This is indeed the scene of construction, and this should be the description."

"Judging from this mural, there is no head or tail, only the middle part, which is a bit intriguing."

"Looking at it from above, it's just construction and testing, and if you look at the middle part, it seems to be on fire, and there are a lot of people who are on fire and struggling."

"Judging from the first half, the position at the back is a deep well, which should be where we are now, and further on, it can correspond."

"The front is no longer important, now look at the back, there are so many mechanisms!"

"Well, judging from the mural, it matches what the grave keeper said."

"What did he say?"

"He said that the group of tomb keepers behind the stone gate are good at water, fire, and raising ghosts."

"Water, I have seen it, to be able to complete such a project, even now, it is very difficult, let alone the past of low productivity."

"What would the fire be like? In the mural, the fire was burned from above. ”

"I don't think this is very scientific and impossible to achieve, after all, there is no fire on it, and there is no chemical fuel in ancient times, I think at most it is through phosphorus and other chemical components, spontaneous combustion in a short time."

"Have you forgotten Gadfly Mountain? How did the fire start? ”

Zhang Gong's face turned red and said in a low voice: "Next time you smell the fragrance of pine, you have to be careful, the feeling of capsizing is too embarrassing." ”

"You hurry up and find out useful information from the murals on both sides, I'll go and see those books first."

With that, Professor Chen walked to the bookshelf. After looking at a few bamboo slips, I realized that these bamboo slips were all written here. After watching the meeting, he said to Zhang Gong: "Old Zhang, come here, make a major discovery!" ”

Zhang Gong and Zheng Suo, who were looking at the mural carefully, immediately gathered around as soon as they heard about the major discovery, and cast all their eyes on Professor Chen.

Professor Chen held up the bamboo slips and said to everyone: "I flipped through a few bamboo slips, and all the things written on them are the construction of this place and the design of the mechanism, which is enough for us to solve the doubts in the ancient tomb." ”

Zheng Suo took the bamboo slip and looked at it, and said excitedly: "Compared to those gold and silver treasures, this is much more valuable!" It's a real value! ”

"Combined with the findings here, I judged that this place should be the place where the designer worked."

Zheng Suo nodded in approval and asked, "Then who is he?" Where do you live? ”

"These bamboo slips don't reflect who he is for the time being, and after slowly reading these bamboo slips, let's see if there is any information about him."

Chen Zhijun and Zhang Gong returned to the mural, and looked at it carefully for a long time, and some parts of it were not too clear, so they asked: "Uncle, I have always wondered why the water here can come suddenly and drop quickly?" ”

"From this mural, there are three water storage holes, the position is obviously much higher than the above, the water storage hole is connected to a spring, at the same time, these three water storage holes also provide power for the mechanism, you see the bottom of this pool, is a conical shape, the lower the smaller it is, the water is through the bottom side of the three holes in and out, there is an important component in the hole, through the inside of the gate to control the direction of the water flow, when the gate is opened, the pool of water flows into the underground river, so that you can explain why the water can be quickly emptied, If the ram is lowered, the pool of water is isolated from the outside, and when the ram of the three storage holes is opened again, the water is quickly replenished through the three thick pipes below, which is the approximate composition of this mechanism. ”

"And how did this seal come about?"

"Water sealing is relatively simple, as long as the accuracy is high enough, the stone can be sealed between stones, which is more common."

"The ancients were so clever! Who invented that trick? ”

"When it comes to the trick, the more famous ones are the Gong Yi and Mozi, but more than 600 years before them, there is a legendary figure, that is, Yanshi, according to the historical document "Liezi", he once made a simulated person with wood and other materials, which is really remarkable, but his 'Wooden Armor Technique' for some reason, but it was lost, until the Spring and Autumn Period, with the Gong Yi and Mozi, there is also the saying of the machine technique. However, there is a clear difference between the two, the 'Wooden Armor Technique' is powered by magnetism and controlled by magnetic tenons, and the pursuit of flexibility is the pursuit of 'Mechanical Technique' which begins to be powered by animals and controlled by wire pivots, and the pursuit is rigidity and killing. ”

"I haven't heard of the Wood Armor Technique, and besides, who is the Gong Loser?"

"Stupid! Call him Luban and you'll know, right? Lu Ban's surname is Ji, Gong Yi's name, the name of the class, known as Gong Yipan, Gong Yi, Ban Yin, and also respectfully called him Gong Yizi, also known as Lu Pan or Lu Pan, the appearance of the wooden armor is also recorded in detail in the "Liezi", I personally think that it is exaggerated a lot, I suggest that you have time to see the Zhou Mu King Kunlun Mountain hunting section. ”

Chen Zhijun was asking shamelessly, suddenly, he smelled a strange fragrance, and slowly, he felt weakness in his limbs, and slowly fell to the ground. Looking around, the others were the same, all staggering and slowly falling down.

When they fell, they all saw it, and not far away, the boy and the girl reappeared, and stood there quietly watching the crowd.
