As soon as the three of them crossed the stone platform, Chu Tianlu found that from both sides of the stone wall in the depths of space, there was a circular pipe with the thickness of a calf, extending along the stone wall. In front of them, the tube formed a ninety degree and plunged under the slate.

Chu Tianlu felt a little strange in his heart, no matter how he looked at this pipe, it looked a bit like a modern sewer, or the kind of pipe of a water pipe!! Could it be that such advanced technology already existed 2,000 years ago?

Chu Tianlu just wanted to squat down to check, and the loach on the side also found the pipe, of course, he also felt incredible, and stepped forward with some exaggeration and knocked it with his hand, and said with an expert look: "This is a stone pipe, it seems that there is already tap water here!" This water must be connected to the stone mill just now, otherwise there is no water lubrication when they grind things, it will definitely not work!! ”

Chu Tianlu wanted to stop the loaches, but the loaches have always been hairy and hairy, and they have always been helpless!! Fortunately, it's not a trap, if it is, he's so careless, something big will happen sooner or later.

What the loach said also reminded Chu Tianlu that he was still a little unable to guess the purpose of this tube just now, and after what he said, he felt that it made some sense. Of course, it's not that it's the water mill, but I think it should have something to do with the stone platform.

"Such a long stone pipe? It can't be!! Even with today's technology, it may not be possible to make such a long stone pipe, which is amazing!! After Qiu Yu saw it, he also felt incredible.

Chu Tianlu thought to himself, I don't know what their intentions are when they place two stone pipes here, but it is certain that the builders must not want this pipe to be damaged prematurely, otherwise it would be easier to use wood or bamboo tubes instead than hollowing out and polishing stones!! Presumably, they wanted the things here to last a long time, so that they would not be corroded and festered by the years.

Walking about four or five meters further, Chu Tianlu saw a rectangular stone pillar with a height of thirty centimeters and a width of ten centimeters, and its upper plane was dug out of a crescent-shaped groove, and the stone pipe happened to be placed in the groove. It seems that this stone pillar should hold up the stone pipe and prevent the stone pipe from being too long and broken. Chu Tianlu looked forward, and sure enough, there was one such pillar holding the stone pipe every four or five meters.

Chu Tianlu also found that there were obvious traces of connection on the stone pipe placed in the groove, but the traces were well hidden, and if you didn't look carefully, you might not be able to notice it.

Chu Tianlu squatted down and looked at it carefully, and found that the connection between the stone pipes was a white substance, a bit like lime powder.

When I was a child, there was a text about the Great Wall, which said that it had existed for thousands of years, but it was still as hard as ever. So Chu Tianlu went home and asked his father once why the Great Wall was still as hard as it had been after so many years of construction.

At that time, his father patiently explained to him the principle, because the ancients had a unique method of construction, the most important thing was the adhesive material they used. Those ingredients are actually very simple, that is, make soup with glutinous rice, add lime powder, and add some eggs. Of course, the heat of boiling and the proportion of materials must be strictly controlled.

There are places on the Great Wall where they are connected so that it is difficult for modern people to separate them. Chu Tianlu looked at the interface in the groove and couldn't help but think of these.

Seeing Chu Tianlu squatting, Qiu Yu also bent down to check, and asked, "Chu Banxian, is there a problem here?" ”

"Boil! No problem, just look, you see, these stone pipes are not one, here, there are their connections. After speaking, Chu Tianlu pointed, and stood up and continued to walk inside.

As they walked, the cold that had disappeared for a short time hit again, and the three of them shivered at the same time, and the lights seemed to flicker, and an inexplicable chill immediately made the three of them feel a little uneasy.

"Master, do you feel it? How do I always feel as if something is following us all the time!! Do you feel it? The loach shrunk his neck again, as if he cared about his little short neck.

"I also felt quite uncomfortable, like the feeling of being targeted by a hunter. It's a little hairy in my heart. Qiu Yu also whispered his feelings, and once again grabbed the corner of Chu Tianlu's clothes.

"Psychological!! Ay! I said loach, Miss Qiu's family went to the grave for the first time, and it was just a matter of not adapting, didn't you brag to me all day long about how you followed your second uncle upside down? I think you're just killing pigs and blowing your ass, pretending to be an expert, right? Chu Tianlu actually had that feeling of uneasiness in his heart, but he knew that he couldn't tell the truth to these two people now, otherwise, the nerve that everyone was holding on might be broken, and if the breath he was holding was loosened, it would be difficult to mention it later.

As soon as the loach heard Chu Tianlu say that he was a layman, he could touch his reverse scales now! Among these people, he has always regarded himself as a veteran, if it weren't for Chu Tianlu being his top boss, he Loach would not have listened to the command of a layman.

I heard the loach say with some protest: "What do you know, this is called the sixth sense!" Do you know what a sixth sense is? This feeling is very important when you are alone in an unknown environment, otherwise, you won't know what happened when you die!! You follow me and see how the fat guy takes you out. With that, the loach strode forward, and in a blink of an eye, the two of them fell a long distance.

Chu Tianlu originally wanted to provoke him and make him not feel timid, but it seems that the effect is quite good.

It has always been Chu Tianlu who opened the way, and now that the loaches have gone ahead, Chu Tianlu has also had time to look around carefully. It turned out that there were not no words here, but those words didn't seem to be intentionally depicted, and there were some seal inscriptions, and some horizontal and vertical scratches, Chu Tianlu guessed that this should be the boring behavior of the workers who built this place during the construction process.

Now he can understand that there is no text here, after all, this is not a tomb in the real sense, so it is normal that there is no text that records the owner of the tomb, or something that represents the identity of the owner of the tomb.

Chu Tianlu looked at it, and a clear scratch appeared in front of Chu Tianlu's eyes. Chu Tianlu's head "Buzz!" With a bang, the whole person was almost choked by the breath in his chest.

It turned out that the scratch that Chu Tianlu saw was a secret mark unique to their Chu family, and only the Chu family knew about it. This was taught to the two of them by Chu Tianlu's grandfather when he took his second uncle and his father to fight in the past, saying that it was passed down from their ancestors.

Chu Tianlu also found out the secret book hidden by his father by chance, and because of curiosity, he spent some effort to write it down.

I didn't expect to see something familiar to me here, how could I not make Chu Tianlu's heart excited!! The secret mark was very simple, an arrow at the front of a straight line, bent to the right, a small dot that was very inconspicuous below the arrow.

Many people may think that this must be a sign of the way. Chu Tianlu knew that it wasn't! This is a mark that tells the Chu family that they have hidden something in front of them. Remind people you know to be aware of the markings left behind.

Although Chu Tianlu was excited and nervous in his heart, he was also relieved. After coming in for so long, there is finally news of the second uncle, and it is very hopeful that he will be the last person to get out of here.

Chu Tianlu was thinking about whether to tell Loach and Qiu Yu the news when he heard a short exclamation coming from the front. Immediately afterwards, the loach man also ran over in a panic, with a white face that was a little scary, and stammered: "Death... Die... Dead person! All of them... It's all... Dead Dead!! ”

Seeing his expression, Chu Tianlu knew that there must be a situation ahead, so he didn't rush forward to check, but whispered to comfort the loach: "Speak slowly, let's come in here and see fewer dead people?" Don't you see a lesbian here? Aren't you afraid that Miss Qiu will go back and tell your jokes to the rice guys? If you see something, say it well!! ”

Chu Tianlu's words were very effective, the loach immediately straightened his chest after hearing this, coughed deliberately, glanced at Qiu Yu with the corner of his eye, and saw that she was not unusual, so he said with peace of mind: "Just now I was walking in front, and there was a small bend not far away, and the strange thing is that the light of the mirror could not shine into that bend." I ventured over to check the terrain and take a look, and who would have thought that the walls over there were covered with corpses. ”
