The direction of the sound was outside the entrance to the second floor when we came, the exact location is unknown, it should be around the cliff at the edge of the dungeon.

After this sound sounded, both the fat man and I stopped our movements and shifted our eyes to the entrance.

After waiting for a while, there was no sound, and the fat man raised the flashlight and went outside, because there was a partition barrier, and he couldn't see the source of the sound at all.

"Xiao Su, didn't we touch some mechanism?"

The fat man asked.

When he asked, I began to feel at a loss, thinking about what we had just encountered.

"From the time we entered the second floor of the main hall, we hadn't touched anything like a mechanism except for the coffin inside the coffin."

I analyzed.

Suddenly I realized what the fat man's so-called mechanism was, and at this moment, the fat man was just as I thought. We uttered one word in unison: "Black box!" ”

It was after the fat man clicked on the last black box that the sound of the stone rubbing appeared.

This mechanism is to open all the black boxes in the eighteen coffins in the eighteen partitions, and the mechanism will be touched!

To determine if our analysis was correct, the fat man moved in front of me from his position near the window and made a probing gesture to me.

I nodded in agreement and told him to be careful.

After that, the fat man held the flashlight in his right hand and walked lightly towards the entrance to the second floor of the main hall.

Standing outside the coffin containing my father's body, I looked at my father's head with his eyes closed, ready to use the rope in my backpack to carry my father's body out of the coffin and go to the bluestone road outside the main hall for cremation.

Before I could reach out to pick up my father's body, the fat man at the entrance heard a surprised voice: "Come Xiao Su!" There's no cave here! ”

I was stopped by his voice and walked briskly towards his position.

When I came to the place where he found a cave, I was even more surprised by what I saw than the fat man's tone.

I saw that in front of us, there was a stone door in the cave that was originally a cliff, but it was now completely open, and the two halves of the door seemed to have a slide, burrowing into the walls on both sides.

The stone door looks like the smooth walls of a cave, and I don't think we'll ever discover this mystery if we hadn't touched the mechanism to separate them.

Behind the separated stone door, there is a downward staircase, under the trance of our flashlight, revealing an extremely wide space under the steps, because we are standing on the second floor of the main hall, the distance is relatively far, and the outline of the inside is not clear. I can just feel that it's hollow inside, very deep.

"I always feel that there should be something outside of this dungeon that we haven't discovered, sure enough!"

The fat man said as he used a flashlight to go up and down the hole that appeared.

"It seems that the real Zhao Tuo's tomb is behind this stone gate!"

I said to the fat man.

"Of course! The main hall in front of him, and the seven buildings below the main hall, did not even have a single hair. No matter how poor this old Zhao Tuo is, he won't be able to bury a pile of headless corpses with him, not to mention modern people! ”

When the fat man talked about modern people, he felt as if he had said the wrong thing, and immediately stopped talking about it.

I know he should be aware that the mention of these modern people reminds me of my father's corpse.

However, it could be seen from his expression that after the appearance of this unique stone gate space, his excitement was revived.

Because we have searched almost the whole hall, and there is not even a single burial object.

And as soon as I entered the underground palace and recognized him, he began to think about the legendary "Yang Sui Pearl", and after an incredible experience, there was no trace of the mysterious bead.

If, as we guessed, behind the stone gate in front of him is the tomb of Zhao Tuo of Nanyue Kingdom, then the "bead" he has been looking for must be under here!

"Su Mo, there's a problem!"

The fat man was excited, but suddenly changed his tone, and said to me with a straight face.

"What's the problem?"

I asked.

"This tomb within a tomb in front of you, your Aunt Ming's team shouldn't have found it!

Also, what was the cause of death of the corpse that we mistook for a "ghost corpse"? ”

I also realized this after the fat man said this question.

Indeed, as he said, put aside the dungeon map first. If the second uncle who came here for the first time, or Aunt Ming, found the tomb within the tomb here, then the black box in the coffin in the partition space we saw should have been opened. Unless there's some other switch to open the stone door!

And after we found the "ghost corpse", there was no other danger like the attack on the other side of the flower, or the row of "ice cellar" rooms!

After our analysis, the fat man and I finally settled on a relatively reasonable reason.

The underground palace here was the team of Aunt Ming or the second uncle, and it was withdrawn after careful exploration. The reason why Aunt Ming would feel relieved to let me and the fat man enter again was because they had already identified the danger in this place, and with my and the fat man's adaptability, they could completely deal with it.

And the corpse that appeared on the second floor of the main hall should be the person in their team who is proficient in punching holes and has better skills.

After they couldn't find the staircase, he was responsible for opening the three-foot-square gap connecting the space between the first and second floors of the main hall.

After that, he drilled into the gap and entered the space on the second floor of the main hall to explore. Judging from the size of his corpse, this is in line with our guesses.

But I don't know what mortal danger there was in the second floor of the main hall at that time, so that this person gave his life there.

Only this one corpse appeared, indicating that the thing that killed him had been subdued by the team of the second uncle or Aunt Ming!

After the appearance of this real Zhao Tuo's tomb, I decided to put aside the cremation of my father's body for the time being. After the fat man and I have explored this tomb within the grave, we will go to "settle" my father.

I can now be sure that the second uncle and Aunt Ming asked me to come to this underground palace, largely so that I could see the coffin containing my father's body.

In order to keep the contents of the tomb untouched in front of my eyes, they didn't even open the black box containing my father's head.

This also shows that they know that the black box contains a head!

But what's going on with all this? The fat man and I still still haven't quite figured out the connection. The tomb within the tomb that appeared in front of them didn't even find Aunt Ming and their team, so there must be a secret hidden in it that they didn't know!

At this moment, the fat man and I were still one in front of the other, and the fat man walked in front of me and behind me towards the tomb behind the stone gate. The fat man's backpack was finally hit on the partition by him and cut open when we heroically attacked the "ghost corpse"!

As we prepared to descend to the tomb behind the stone gate, the backpack let us place on the edge of the iron rod bridge. Each of us took a flashlight and put two "Gamba Bean" grenades in our pockets and walked down the steps!

"I said, Xiao Su, this is called the real tomb! You see that this brick is a brick, and the tile is a tile, and it makes people excited when they look at it! ”

The fat man was in front of me with a flashlight on the grave road, and he couldn't hide his excitement at all.

Looking at the structure of the tomb in front of me, I learned something in my two years of archaeological studies and completely jumped out.

About the introduction of the ancient tomb structure of the Han Dynasty, the tomb of the Han Dynasty, pay attention to the shape of the tomb is regular and smooth, just like what I saw in front of my eyes.

Most of the tomb passages under the steps are naturally formed cave-like shapes, and the tomb passages are about three meters high, with obvious chiseling marks at the top. The sides are very wide, about six meters wide on the left and right, and the walls on both sides still show signs of chiseling. These two carved marks make this tomb look much smoother and more regular.

We walked for about seven or eight minutes from the steps about five meters down into the tomb, and the otoliths and the burial chamber still did not appear.

"Damn, look at it, Xiao Su, this tomb is for you, it's so neat! And it's so long! ”

The fat man holding a flashlight in front of me was still admiring the tomb in an excited tone.

I didn't care about his admiration and excitement, but I was always vigilant about my surroundings.

Now I want to calm the fat man, but he may not be able to calm down, the temptation of "Yang Suizhu" is too great for him.

On the contrary, the allure of such things as gold and silver is far less attractive to me than the bizarre things that have happened to me. So at the moment I am still awake, holding the dagger in my hand all the time, and the "Gamba Bean" grenade in my pocket is also on standby at all times.

After walking a distance of about thirty meters, the first burial chamber finally appeared in front of our eyes.

The structure of the tomb was still excavated by hand, and the door of the tomb was about two and a half meters high and one and a half meters wide, just wide enough for the fat man's body to enter, and the gaps on both sides were not enough for me to enter the tomb with him.

In the corner of this burial chamber, there is a small table with some exquisite ivory bowls and chopsticks, and next to the chopsticks there are some things that resemble iron skewers with weathered meat!

"Hey! Xiao Su, look at it, this Zhao Tuo Lao'er is still the originator of the barbecue industry! ”

The fat man quipped with the sapper's shovel and the iron skewer.

"Haven't you heard of the tomb of Lady Xinchai?"

In response to my reminder, the fat man slapped his head, shook his head as if dissatisfied with himself, and said: "Look at my head, by the way, that woman is the originator of the barbecue industry!" Are they of the same era? ”

The fat man pointed to this tomb, meaning to ask Zhao Tuo and Mrs. Xin Chai.

Seeing that I nodded, he continued: "The most popular thing in the Han Dynasty was barbecue! Ha ha! ”

Just as we were happily discussing the popularity of food in the Han Dynasty, the sound of water suddenly came from inside the tomb, which seemed to be someone carrying a bucket and dumping somewhere!
