Cao Cao hurriedly looked up, followed the direction of Princess Sanssouci's finger, and sure enough, he saw something strange on the walls on both sides of the tunnel.

Just now, he was only talking and pondering, and he didn't notice the change in the situation in the tunnel.

First of all, the tunnels here are much wider and more regular than those outside, which obviously shows that more care was taken to build this section of tunnels.

Secondly, the outside tunnel is all earthen walls, which retain the original appearance of the excavation and excavation, while here the walls on both sides are all built with green bricks, and the material and size of the green bricks are the same as the brick walls of the portrait of Nuwa Niangniang in the ear room.

Finally, and most crucially, there seem to be portraits on the blue brick walls on both sides.

Princess Sanssouci pointed to the portraits on the walls.

Cao Cao carried the princess on his back and approached the 'wall', holding up the torch aloft to watch carefully.

In fact, at this time, the role of the torch is no longer great, because the white light coming from the distance in front of it basically reflects the tunnel as if it were day.

Cao Cao could see clearly that the image above was a large snake and a round thing.

The serpent was as long as a bowl, and was crimson in color, with two horns on its head, two red whiskers hanging down its chin, and its lantern-like eyes were round and large, and they were also red, and its mouth protruded forward like a pig's arched mouth. Strangely, there is also something like a flame spitting out from the side of the mouth.

Princess Sanssouci frowned: "Brother Cao, why is this painting so strange, is this a snake or a dragon?"

"Well, it's true that it looks like a snake but not a snake, like a dragon and not a dragon, but in my opinion, it should be called Candle Nine Yin. ”

"Candle nine yin?"

"Not bad", the old man Feng took over the voice, "The ancient divine book "The Classic of Mountains and Seas" once recorded such a divine beast, with a human face and a snake body, a red body, and a fire spirit in its mouth, and its name is called Candle Jiuyin, also called Candle Dragon. “

It turned out that the old man Feng had also discovered the portrait on the wall a long time ago, the difference was that he was looking at the right wall, while Cao Cao and Princess Sanssouci were looking at the left wall.

Only then did everyone notice that the images on the walls on both sides were exactly the same, and that the other was followed by a snake and a ball.

In other words, all the walls in this tunnel are painted with exactly the same portraits.

The explanation of the old man made Princess Sanssouci even more confused, and she still couldn't figure out whether it was a snake or a dragon.

Looking at her confused eyes, Cao Cao also shook his head and smiled bitterly, Candle Jiuyin is a mythical beast in mythological stories, I don't know if there is anything in the world, what is the meaning of a dragon or a snake!

On the contrary, it was a round spherical thing, and it was impossible to tell what it was.

It was smaller than an egg and not far from the mouth of the serpent, but it was painted very round, and it was clearly painted with a lot of effort.

"It's the sun, isn't it?" Princess Sanssouci listened to the two of them talk about myths and stories from time to time, and couldn't help but think of Kua's father.

This sun is too small!

"Could it be gentian?" guessed the wind senior.

It's not very likely, whether it's a dragon or a snake, if you spit out all your guts, you can still live?

Cao Cao looked at the ball carefully, and said to himself: "This thing, how does it look familiar, it seems to have been seen somewhere." ”

After thinking for a while, Cao Cao suddenly asked Princess Sanssouci to get off his back, and then squatted down to lift her skirt.

"Brother Cao, ......" She glanced at the old man, and her face turned crimson.

Cao Cao knew that she had misunderstood, and hurriedly explained: "Princess, you have ..... on your leg."

"What's wrong with my leg?" she said, thinking the wound had recurred.

"No, oh, I mean this pattern on your calf. ”

Only then did Princess Sanssouci react, she pulled up the lower end of the squirrel, revealing her smooth and slender legs, Cao Cao could see very clearly, her jasper-like left calf was embroidered with a spherical pattern.

It's exactly like the image on the wall!

No wonder Cao Cao felt familiar, and he glanced at it when he helped her treat the wound, but he didn't care about it at the time.

Princess Sanssouci also realized the problem, she looked up at the wall, then looked down at her calves, and said, "How can this be, this pattern has been around since I can remember, it should have nothing to do with the one on it, right?"

"Since childhood?"

"Yes. ”

"Why do you want to tattoo this pattern?"

"It was the big boss who stabbed it, and I heard that every generation of our Ying clan will be stabbed after birth. “

"Does each generation mean anything?"

"That's what the big boss said, as if it has been like this since the ancestors died in the country, and as for what it represents, even the big boss can't say. ”

Everyone present knew in their hearts that as the Great Qin Imperial Family, the 'Jun' child of the deceased country must have this pattern tattooed on his descendants, which must have a deep meaning. Besides, every big boss of Lu Wanggu is a member of the Qin clan, and they should also inherit some kind of mission, such as helping the master tattoo this pattern from generation to generation, they must want to warn something, but no one knows.

Cao Cao looked at the Feng seniors with inquiring eyes, and he also shook his head and said nothing, staring at the white light blankly.

The further you go, the brighter the white light becomes, and the penetration is extremely strong, in fact, at this time, there is almost no need for torches.

"Senior, what are you thinking?"

"This white light doesn't seem to be the sun's rays. ”

"The younger generation also thinks so, when we entered the tunnel, it was close to Shenshi, and we came in for so long, if it was really sunny, it wouldn't be so bright. ”

"Could it be ......" The old man Feng said halfway, and suddenly gasped, and his face changed greatly.

"What is it?" Cao Cao hurriedly asked.

Old Senior Feng didn't answer, but turned his gaze to Princess Sanssouci, "Princess, have you ever heard of the words 'Night Pearl'?"

"The Pearl of the Night?" is it...... What is it?" she said, dazed.

The old man moved his gaze to the pattern on her leg again, and she suddenly realized: "This pattern is the pearl of the night?"

Senior Feng nodded, and asked Cao Cao again: "Does the young man know what the Night Pearl is?"

"The younger generation has heard of this, but has never seen it. ”

"The old man grew up by the sea since he was a child, and he has heard many stories about the night pearls from the elders, and he has also seen the fishermen pick them, but they are all very small 'grass beads', and the legendary 'dragon balls' have never had a relationship. ”

"But how can there be a night pearl here?"

Cao Cao was even more surprised, didn't the old man say that this thing was made in the sea?

"Hehe, princess, this night pearl is your family!"

"My family?" Princess Sanssouci couldn't believe it, she didn't know what it was, and she had never heard anyone from her clan or anyone in Lu Wanggu mention it.

"Oh, to be precise, it's the things of your Ying ancestor. ”

Cao Cao and the others understood a little bit at this time, and what the predecessors said was right, after all, Princess Sanssouci is now the only bloodline of the Ying family, and the things of the ancestors can naturally be said to be hers.

"Does the predecessor have a basis?"

The old man said this, and he was not completely sure, but the old man listened to the fishermen too much about the story of the night pearl. The palace of Qin, the candles and nine yin, the white light, and the patterns on the princess's legs and walls, these are strung together, which made the old man guess so. “

"But how can this legendary thing be in this tunnel?"

"Have you forgotten? When Qin Shi Huang visited Mount Tai in the east, he unfortunately contracted a serious illness, and he recuperated here on the way back to Xianyang, and died here. It is said that the First Emperor once got a huge night pearl, which has been regarded as a treasure since then, and is always carried on his body, even every time he goes on a tour, but after the death of the First Emperor, although his body was sent back to Xianyang, the night pearl disappeared out of thin air. “

"The predecessor means that the pearl of the night is...... What the First Emperor left behind?"

Cao Cao and the others finally understood.

"Could it be that this tunnel was dug by someone sent by the emperor?"

"There is such a possibility," Cao Cao said along her train of thought, "even if this tunnel has existed for a long time, it cannot be ruled out that those white bones in the ear chamber are the soldiers sent by the First Emperor to bury the Night Pearl." ”

"Why did he bury the Pearl of the Night?"

It is said that when the first emperor was critically ill, the heir was not the youngest son Hu Hai, but the eldest son Fusu who was far away on the border, and it was Zhao Gao and Prime Minister Li Si who tampered with the edict and planted the seeds of the great Qin in the future. Although these events are recorded in the history books, but there were only a few people who knew about it at that time, the incident happened suddenly, the situation was dark, and the truth was never known, but the first emperor must have made some arrangements on his deathbed, maybe he really sent someone to seal the night pearl in this tunnel.

Speaking of which, it was always a guess, the three of them continued to move forward along the tunnel, and walked seven or eight feet away, and saw that the walls on both sides were full of the same pattern one after another, although they wondered why they were drawn like this, but no one spoke again.

Suddenly, I reached the end of the tunnel, and it turned out to be a 'dead end'.

There is no road ahead, what can I do, I can't turn back, those earth dragon rats are still outside.

Similarly, the pattern on the walls came to an abrupt halt.

But the white light was still there, and it became amazingly bright.

The trio looked against the white light and found that it was coming from the wall on the right.

Along the way, the patterns on the walls on both sides are perfectly symmetrical, while the finish point is only on the left side, and the right side is empty.

Did you forget about painting at the time, or did you have another mystery?

The walls looked all loess, and the surface was wet, no different from the tunnels outside, but there was a small hole in the upper right corner, and white light was coming out of it.

Whether it was the negligence of the soldiers who forgot to block it back then, or the fact that the loess fell off over the years, or even someone deliberately left a hole to leave a hint for the visit of destined people in the future.

With the previous experience, Cao Cao used wooden rafters to poke the loess, and sure enough, the appearance of green bricks was revealed, Cao Cao worked harder, and as the loess fell, a blue brick wall that was exactly the same as the ear chamber was exposed.

Moreover, the pattern on the brick wall is also the surrounding 'Hui' shaped cloud and thunder pattern, and in the center is a portrait of Nuwa Niangniang.

Is there a hole behind the brick wall?

Cao Cao kowtowed a few times to the portrait of Nuwa Niangniang, and then got up and poked the green bricks at the holes with wooden rafters, as the green bricks fell, the holes became larger, and more white light shot out in a volley, and the tunnel was suddenly as bright as day, and the three people who reflected the thorns couldn't open their eyes.

Cao Cao struggled to keep his eyes open, and through the hole, he could vaguely see a high platform inside, on which there was a vague round object.

And these white lights are emitted from it.
