After thinking about it, Bai Xiaobai is the best at this kind of thing of finding people.

"Bai Xiaobai, now look for Lu Wei's whereabouts." Su Man patted Bai Xiaobai's head and said. Bai Xiaobai shouted twice at Su Man, turned around and ran towards the gate.

Su Man felt strange, didn't Lu Wei enter here at all?

But strange is strange, everyone still followed Bai Xiaobai outside. ran outside, Bai Xiaobai didn't run far, but turned around and went to the back.

Su Man and the others followed Bai Xiaobai around to the back of the opera house, only to find that there was a small door here.

When you go inside, you can see that this seems to be a reserve warehouse of the opera house.

"Lu Wei, Lu Wei, are you here?" Su Man shouted around, but received no response. Looking at Bai Xiaobai again, he walked here but stopped moving.

It's just constantly "whining" and spinning in place.

Su Man knew that Bai Xiaobai couldn't detect this, which meant that Lu Wei suddenly disappeared here, and put Bai Xiaobai away again.

Then leaning down, Su Man groped back and forth on the ground, trying to find some switches and other things.

"Vine, what's going on? Is Lu Wei here? Xuan Yu'er saw Su Man squatting down and groping for something, and asked curiously.

"Bai Xiaobai found out that Lu Wei suddenly disappeared here, and he lost his clues here, I guess there must be something like a secret passage switch here, Lu Wei must have accidentally touched it and fell. Otherwise, we will definitely wait for us to go down together when we find the secret passage. Su Man replied.

"Well, that's right! Let's find out! Saying that, Xuan Yu'er also squatted down and groped the ground together.

Pi Jun said: "It doesn't have to be the ground, I'll look on the wall as well." ”

Then Pi Jun, Gao Zhanbo and Su Yuantong looked for them on the wall. However, everyone searched for a while and found nothing.

Xuan Yu'er stomped her feet: "I hate it to death, I will encounter some secret path if I have nothing to do." As he spoke, he kicked his foot towards a box on the side, and then jumped up on the ground with his feet covered: "Oops! It hurts me to death! Oops, oops. Ay...... Yes! ”

Before she could finish shouting in pain, Xuan Yu'er exclaimed, and then a big hole was revealed in the ground under Xuan Yu'er's feet, and Xuan Yu'er fell directly below.

Su Man hurriedly lay down at the entrance of the cave, but fortunately, the cave was not deep, Su Man hurriedly asked, "Yu'er, are you okay?" ”

I saw Xuan Yu'er rubbing her fart. He replied with a bitter face: "Why are you okay, didn't I just say that it was a secret way!" It doesn't make me hurt and fart. The ...... of the pain in the strain"

Su Man saw that Xuan Yu'er was fine. "Ya * Wen * Yan * Qing * Shou * Fa" smiled: "Yu'er, you discovered the secret passage." Awesome! After speaking, he took out a jump rope and threw it down, and then dragged it with Pi Jun, and the others jumped down one by one.

In the end, after Pi Jun went down, Su Man shouted to everyone to stay away, and she jumped down directly.

This secret passage is very strange, I don't know how it was built at that time, and there is a faint light in it when there is no light.

However, in order to see more clearly, Su Man still took out the largest light tube to illuminate the walls of the secret passage on both sides.

"Lu Wei, where are you?" After coming down, everyone was shouting Lu Wei's name. It's just that Lu Wei still didn't come out to respond.

Walking along the secret passage with a glimmer of light, everyone finally came to a relatively spacious place.

The ceiling is a cave-like vault, and in the center is a miniature version of the "Pantheon" rotunda.

There are two rooms on each side, and one room in front of them, so that the five rooms show a symmetrical distribution of pentagrams.

Everyone looked at the four small rooms one by one. Each room is about ten meters long and four or five meters wide, and contains some beautifully shaped stone slabs. But there's nothing special about the four rooms.

Eventually, everyone came to the fifth room in the center, and everyone felt different as soon as they entered this room.

From the hall, the five rooms are the same, except for their location, but once inside, they are larger than the other four.

After entering this room. They found a marble statue on the front, with some words describing something.

"Zhong Tao, come and see what is written on this?" Su Man beckoned Zhong Tao over and said.

Zhong Tao came over and looked at it for a while and said: "I don't know what kind of text this is, maybe it's an ancient text, anyway, it's not the same as the current Portuguese, and some shadows can be found in individual words, but they can't be coherent." ”

"Oh, so we can't know where it is?" Su Man said with some disappointment.

"But it's so strange! There is nowhere else to go here, where did Lu Wei go? Xuan Yu'er asked with a wink.

Su Man circled the room, and finally his gaze stayed on the back of the marble statue.

There are some holes in the back wall that are blocked by mud, but the mud on this hole is probably too old to fall off a bit.

Su Man pulled out an iron shovel and knocked it on, and then the dirt on the wall fell again.

"Manman, there is really an exit here, but if it is blocked, Lu Wei can't be shrunk through, right?" Xuan Yu'er said.

"Anyway, we can't find it for the time being, so let's go over and take a look." Su Man replied.

Everyone was also very curious about what was behind this, so they followed Su Man without much nonsense. After getting through, there was a long and narrow passage, and I made a few turns along the passage to the front of a wall.

Su Man took out a sledgehammer and chiseled it against the wall, picking it up and chiseling it for a while before opening the wall.

When they came to the back, they found that it looked like a modern residential building, but it was clearly not. The walls here are thick enough to effectively carry the pressure above, and each walled house is about three floors long.

The floor is paved with fishbone tiles, and even the bricks next to it are carved with patterns, and it is obvious that this place should have been inhabited by people of high status, and the slum would not have been built so beautifully.

"Oh my God, when was this building, there was already a drainage system here." Pi Jun was originally doing this work before the end of the world, so he knew a lot about the pipeline system, and said in surprise.

"Really! There are also toilets! Xuan Yu'er came out of a room and said.

"Could this be the current underground structure?" Su Man guessed.

"Absolutely not, look here." At this time, Gao Zhanbo, who had already passed through one room to another, said.

When they followed, they found a road made of bricks, and then came to an opening with two grooves, and under the grooves were two square pools made of bricks, and at the top of the pools were two grooves, which were connected to another large rectangular pool.

"What is this?" Xuan Yu'er asked suspiciously.

Seeing that everyone was looking at him suspiciously, Gao Zhanbo explained.

"This is an ancient water supply system, and it was built very advanced, and the water flowed down the brick channel above, to the groove and into the tank below, and when the tank was full, it flowed down to the square pool below, and there were holes and grooves flowing out." Gao Zhanbo pointed to the structure above and said.

"I don't think so, maybe this is an ornamental pool built by later generations?" Xuan Yu'er retorted.

"No, Yu'er, what the senior engineer said is right." Zhong Tao walked under the stage while the two were talking.

"You know again?" Xuan Yu'er pouted.

"Here's an introduction, it seems to have been developed by archaeology." Zhong Tao pointed to a sign and said.

"Huh? It's true? Let's talk about it. As soon as Xuan Yu'er heard that there was a new discovery, she had already forgotten everything she had just said wrong, and hurriedly ran towards the position where Zhong Tao was standing.

Only then did Zhong Tao tell everyone about the situation described above.

This is the underneath the Caprarius neighborhood, and the buildings here are more than 2,000 years old, and are said to have been built during the time of the tyrant Nero.

This building is a typical example of residential buildings inhabited by the more affluent people of the ancient Roman period, the lowest floor is actually an ancient shop, while the second floor has a terrace, where the wealthier people generally live, and the top floor is inhabited by some of the poorer people, because there are no compartments there at all.

But compared to other places, this is a prime location, because of the reservoir that Gao Zhanbo just saw, because there is an independent water source, so people in other places are more fortunate than other places.

"The wisdom of people in ancient times was not simple, but does it have any effect on us?" Xuan Yu'er asked sharply.

"Uh...... It doesn't seem to be the place we're looking for, and there's no trace of Lu Wei. Su Man replied to Xuan Yu'er.

"Well, let's go back! Maybe there's something over there that we haven't noticed. Gao Zhanbo said.

Su Man nodded, and everyone walked towards the place where they came again.

"Huh? What about the big hole in the wall? How is it gone. When the people came to this location, they didn't see the big hole that had been opened before.

"Sure enough, there are two explanations: either we misremembered the route and got lost, and the big hole was not opened here; Either that or the wall may have a repair function. Su Man said.

released Bai Xiaobai again, Bai Xiaobai walked around, and shouted "whooping" somewhere on the wall.

"It seems that we haven't lost our way, it is indeed here that we came out before, and if we go back, it seems that we will still dig the wall, hoping that the passage will not disappear, so we can only go out." Su Man said.

Taking out the sledgehammer again, Su Man bombarded the wall again, and finally exposed the passage behind him. Thankfully, the passage doesn't move around.

The crowd quickly entered the narrow aisle and followed the aisle back.

Returning to the place where the marble and granite sculptures were kept, the group scrutinized every part of the room in the hope of discovering something different.
