Ou Zhou nodded, so he and Shui Jingxin were in a group and looked from left to right, while Jiang Yang and Ke Fei'er were in a group and looked from right to left.

With the help of the light of the dragon balls, the two groups carefully examined the differences and changes in the chisel marks along the stone walls of the stone chamber and made detailed comparisons. Soon after, two more similar traces were found.

The two groups of people recorded it bit by bit in a notebook, and after full thought and imagination, they drew it.

Another hour passed, and the four sisters and brothers put the three patterns together, and after slowly moving and splicing, Ou Zhou and Jiang Yang's eyes widened, and there was a bang in their brains.

"Senior brother, do you think this is the floor plan of the interior of the Mausoleum of the First Emperor?"

"Senior brother, this picture is very similar to the scene we saw in our dream last night!"

Shui Jingxin and Ke Fei'er glanced at each other, a flash of inspiration flashed in their minds, and they were surprised: "Could it be that the person who lives here is the craftsman who built the mausoleum of the First Emperor?" ”

Ou Zhou nodded: "If that's the case, the existence of this stone chamber is logical." ”

Jiang Yang continued: "Obviously, this group of people knew that once the mausoleum was built, the First Emperor would definitely kill them, so they tried every means to escape to this cave, and in order to avoid pursuit and survive, they dug this stone chamber and hid it as a permanent hiding base. ”

"But what did they do with the huge amount of stone chips when they dug the stone chamber?" Shui Jingxin is a girl in the end, and carefully raised a new question.

"I think that's how it should be. At first, they hid in this cave, and found that the terrain was difficult to defend, and the most important thing was that there was a water source. In order to be on the safe side, it took countless painstaking efforts to dig out this stone chamber. I suspect that they should have transported the stone chips to the mouth of the cave, and when the flash flood occurred, they threw the stone chips down and let the flash flood wash away. ”

Jiang Yang nodded appreciatively: "With such a huge project, with their numbers, it will take at least ten years to complete the excavation of this stone chamber!" ”

"Moreover, it seems that they hid until after the destruction of Great Qin, and then they dared to walk out from here." Ke Feier said thoughtfully.

"In order to survive, they are really hard and lonely!" Shui Jingxin sighed.

"The Mausoleum of the First Emperor was built in 247 BC, and the Great Qin Empire fell in 207 BC. In other words, who is going to hide in this cave for at least forty years! Ou Zhou said.

Jiang Yang nodded: "If they hide here when they are thirty years old, they can only walk out of here at the age of seventy." My goodness, forty years, the vicissitudes of life, how many things will happen in this period? ”

"In this way, there should not be many people who can get out of here."

"Yes, how much will the trajectory of life change in forty years?"

"Extrapolating from the number of dishes and chopsticks inside, the number of people who walked out of here in the end was still no less than ten."

"Then the number of people who escaped from the mausoleum here will not be less than twenty."

"Yes, for forty years, there is a shortage of doctors and medicines in the cave, and the living conditions are difficult, and at least half of the people can't survive the moment of going out."

"When they return to their hometowns, it is doubtful whether anyone will recognize them, or whether their family members are still alive."

"The world has changed, thirty years of generation, this group of people hid for forty years before going back, if there are still people in the family, I am afraid it will be difficult to recognize each other."

"Alas, this is all the sin created by His Majesty the First Emperor!" Shui Jingxin sighed.

Ou Zhou looked at the map, raised his eyebrows, and said, "Senior brother, what do you see here?" ”

Jiang Yang looked at it for a long time, and said suspiciously: "This seems to be a secret passage?" ”

"It seems to be a secret passage into the Mausoleum of the First Emperor?" Shui Jingxin said in surprise.

"To be exact, it should be the secret passage for this group of people to escape from the Mausoleum of the First Emperor." Ou Zhou corrected.

Ke Fei'er looked down for a long time and said: "If this is really a secret passage to escape, they have to hide in the secret passage before the 30,000 tons of mercury in the Mausoleum of the First Emperor are poured into the underground lake, otherwise even if they are not killed, they will die of mercury poisoning." ”

"That's right, these people should have been ready to flee a long time ago. They must have taken refuge in a pre-dug secret passage a day or two in advance. Jiang Yang analyzed.

"Among the craftsmen who built the mausoleum, those who were able to survive until the last moment were the craftsmen who were responsible for the pavilion in the sky and the mercury injection. This is one of the last few processes of the mausoleum. Ou Zhou said.

Jiang Yang agreed with him and said: "Moreover, after they hide in the secret passage, they should close the entrance at the very moment, otherwise the matter will be revealed, after the mercury is injected into the underground lake, the poisonous gas will spread out along the secret passage and erode their bodies." ”

Ou Zhou asked, "Senior brother, what direction did you say the location of this secret passage?" ”

Jiang Yang said with a smile: "Senior brother, we and the First Emperor are also friends in our dreams, what are your plans to ask about the location of the secret path?" ”

"The secret passage is a flaw in the Mausoleum of the First Emperor, as a friend, it is reasonable to be reasonable, after finding the secret passage, we are all obliged to block him."

"Hahaha, junior brother, two thousand years have passed, and even if that secret passage exists, it has long been buried by the changes of nature!"

Shui Jingxin said: "The coordinates of the ancients do not know what they are based on. According to modern theory, the location of the secret passage would be on the side of the cave, that is, in the southwest. ”

Ou Zhou nodded: "This logic seems to be valid, after this group of craftsmen escaped from the secret passage, they crossed the mountains and fled here, and accidentally discovered this cave, so they hid." ”

"Senior brother, although your idea is very good, there is a separation zone three kilometers away from the scenic spot. This escape passage should be within the isolation zone, how can we find it? ”

"It's an indisputable fact, and it's really not easy." Ou Zhou said and looked at the time, "Hey, we are only concerned with analyzing the problem, it is more than six o'clock, I'm afraid that the sky is already dark." ”

Shui Jingxin took out his mobile phone and looked at it, and shouted, "My good man, it's really dark, why don't we go back?" ”

Ke Fei'er joked: "Or, let's follow the example of the ancients, live here tonight, and experience the fun of the wild?" ”

"Don't do it, it's winter, although the stone room is not cold, but it is not warm either, be careful to freeze into popsicles in the middle of the night."

Jiang Yang said with a smile: "This kind of place, if it is autumn and summer, it doesn't hurt to live there, but now in this season, it is indeed not suitable." ”

As they spoke, they walked out of the stone chamber and walked along the entrance of the cave, until when they came out of the cave, the sky was full of stars.

I saw a crescent moon hanging obliquely in the eastern sky, and the sparse stars loomed.

"It seems that we have to raise our spirits to deal with the descent of the mountain." Ou Zhou reminded.

"Senior brother, you take care of the senior sister, and I am in charge of the beautiful sister. The two of us are a couple, with dragon ball lighting and a crescent moon like a hook, so there's nothing to worry about. ”

With the help of Dragon Ball lighting, the two pairs of people paid attention to their feet, and at the same time did not forget to chat a few words: "Senior brother, what do you say is the harvest of our trip today?" ”

"It's that simple picture, what else can there be?"

"Actually, for us, it doesn't mean much to have and don't have this diagram. We didn't think about trying to find that secret passage, let alone enter the Mausoleum of the First Emperor. ”

"Senior brother, you say, if we send this sketch to the Management Committee of the Mausoleum of the First Emperor, will they believe it?"

"It doesn't matter if they believe it or not, the point is, it may cause us unnecessary trouble."

"Yes, if people ask, why do you say that this is the secret passage map of the Mausoleum of the First Emperor, and how did it come about? None of us could answer. ”

"What if you tell them that this sketch is from this stone chamber?"

"They must ask, why do they say that the simple map is the secret passage of the Mausoleum of the First Emperor?"

"Based on the age of that stone room, the distance from the Mausoleum of the First Emperor is not too far."

"What do you mean, do you want to say it to the scenic spot or not?"

"Senior brother, to tell you the truth, whether it is for the safety of the Mausoleum of the First Emperor, or for the great archaeological value of this stone chamber. It is necessary for us all to tell the management committee of the scenic spot. ”

"Hehe, why aren't you afraid of people interrogating us, why did you find such a secret stone chamber?"

"Curious, we like to explore!"

"Two sisters, can you also express your opinions?" Jiang Yang asked instead.

"You two are the inheritors of the Xuanji Sutra, and the discovery of this stone chamber and the simple diagram is related to the comfort of the First Emperor's Mausoleum. Whether it is public or private, you should tell the scenic spot management committee. Shui Jingxin said.

"I basically agree with the water chick." Ke Feier said.

As they spoke, the four siblings had arrived at the red sandstone cliff.

"Alright, let's go down!"

Ou Zhou explored the way ahead, and the water followed quietly.

Jiang Yang and Ke Fei'er were in a team, and the four of them fought together, and they went down the mountain cautiously, and another half an hour passed.

Shui Jingxin looked up at the top of the cliff and sighed, "When I went up, it took less than ten minutes. ”

"Isn't there a saying that it's easy to go up the mountain but hard to come down. Besides, it's night again. Kefier said.

"Our trip is not in vain." Ou Zhou said with a smile.

"Yes, at least, the historiography has one more research on the construction of the Mausoleum of the First Emperor." Jiang Yang said.

"And we can be regarded as a reward to His Majesty the First Emperor. After all, for no reason, I got a flat crown! ”

"Haha, which Her Majesty's golden crown, how to repay it!"

"Hehe, Her Majesty's golden crown will be ours sooner or later. After all, there's a bet there! ”

That night, when I returned to the house at the foot of Lishan Mountain, it was almost ten o'clock. The restaurant has long since ceased to be served. The four siblings had to eat instant noodles and dealt with it casually.

When they got up the next morning, it was already past eight o'clock, and after washing, the four siblings went to eat the free breakfast that was not sumptuous and not sumptuous breakfast.

Same as yesterday, Shui Jingxin and Ke Fei'er moved some of the plates piled up like small hills to Ou Zhou and Jiang Yang's plates, and then they each buried their heads and began to work hard to deal with the food on the plates.

"Before you know it, we've been here for three nights, are we going to continue to play at other attractions, or are we going home?" Ou Zhou suddenly asked.

Shui Jingxin continued: "This trip can be regarded as an unexpected joy, and the so-called pride cannot be repeated." Let's take Her Majesty's Golden Crown and His Majesty's Crown of the First Emperor and go back! ”

"That's it, you two haven't seen your parents for five months, and it's almost the Spring Festival, so it's time to go back early." Ke Feier also said.

"I'm okay with that." Jiang Yang swallowed a mouthful of bacon.

"Let's set off after eating, first go to report the sketch and the stone room to the scenic spot, and then we will go to the airport."

After the meal, several people retreated from the room according to the plan and made a special trip to the scenic spot.

Although the relevant personnel in charge of receiving them in the scenic spot felt very ridiculous when they looked at the sketch map, they were still very interested after hearing them talk about the cave and the stone chamber.

After all, as the person in charge of the scenic spot, the geographical environment around the Mausoleum of the First Emperor must be familiar, and they know the cave, but it is too steep and no one has ever gone up.

Now I heard that you can climb it through the red sandstone wall, and there are a lot of bronzes in the stone chamber inside, which is naturally a great joy.

The person in charge was condescending and respectful, and once invited a few teenagers to go with him, but Ou Zhou and Jiang Yang refused on the grounds that there was something wrong.
