Live: I can issue death notices

"Besides, I also have a question, what is this channel used for?"

"Don't discuss what the channel is for!"

"How was it built? Who built it?"

"Such a large project cannot be done quietly."

"It's not very big, if it's a national project, it's not difficult to build."

"National project? Do you have any friends in the secret department? Tell me a few words."

"That's right, anyway, everything in the live broadcast room is anonymous, and the country can't find you."

"I've never heard of such a thing..."

"I do not have either...."

........the other side

Two-headed shark, breaking the silence of the four

"I think we should stop for a moment, something is wrong here."

"It is impossible to have such a building, because it is meaningless and the amount of work is too large."

"440 meters. It is known that the height of the wall and the length and width of the passage are both 2 meters and the thickness is also 2 meters. If the cement on the ground and overhead is the same thickness, 18 tons of cement will be used for each meter of passage."

"Then the 440-meter cement passage requires 7920 tons of cement."

"A fully loaded cement truck can transport 40 tons of cement, which means it needs close to 200 trucks."

"The project is too big, and this channel doesn't look like it's only 440 meters."

"If the channel is 880 meters long, it will take 1 tons of cement and 400 trucks."

"if...."

The double-headed shark did not continue to give examples, because the numbers in front of him were already astonishing enough.

Ghost Shark panicked a bit,

"Then what should we do? How about we wait?"

Tiger Shark speaks abruptly

"Who are we waiting for? Waiting for the people from the local correctional center to save us? Are you fucking stupid?"

The tiger shark walked up to the wall and punched it heavily on the wall. The wall did not move at all, only a muffled impact sound.

"Second, is it possible that it's underground?"

Two-headed shark nodding noncommittally

"Of course it's possible, but the amount of work will be even greater, and 4 cubic meters of soil will need to be excavated for each section."

"And it's not easy to pour such a large cement building underground."

Tiger Shark punched the wall with a punch, each punch had a different landing point, trying to find a flaw.

But every time he punched it, it made almost the same sound, and there was no useful clue at all.

"How about I see if there is anything strange on the top?"

Ghost Shark suddenly suggested, pointing to the top of his head.

"That's fine, but be careful, I'm afraid there will be traps, fourth brother, give me the oil lamp, and you give the third brother a cushion."

The double-headed shark thought about it and nodded.

Blood Shark didn't hesitate, handed over the oil lamp, and fastened his horse.

The ghost shark stepped onto the shoulder of the blood shark with a light leap, and the blood shark kept tapping the ceiling with its knuckles, while the blood shark kept moving and changing positions underneath.

After a long time, Ghost Shark felt that his fingers were about to break off, but there was nothing abnormal on the smallpox.

"Come down, there's no need to keep knocking."

The two-headed shark frowned.

Ghost Shark breathed a sigh of relief, and jumped off Blood Shark's shoulders.

"Now let's summarize the known clues. The minimum diameter of this place is more than 440 meters."

"Walls, ceilings, and the ground are made of concrete poured in one piece. There are no organs or hidden compartments."

"The length and width of the channel are both 2 meters, which is a standard square."

"So far, the passage is all straight lines, no curves, no markers"

"For the time being, I haven't figured it out yet, what the hell are you going to do?"

After listening patiently, the tiger shark opened its eyes again

"Everyone move your feet, second child, make a sign here, and put down a fluorescent bead."

"Everyone holds a lighted fluorescent bead in their hands. By the way, what is the visible range of this fluorescent bead?"

The double-headed shark didn't think about it, and directly reported the data

"Visible range of 45 meters -50 meters"

"Let's go back from here, the first point is here, the second point is me, the third point is the second child, the fourth point is the third child, and the fifth point is the fourth child."

"Everyone calculates their moving distance, it's only 45 meters, don't run too far, stop when you see the fluorescent beads start to darken, everyone put the fluorescent beads against the wall, if there is an arc in the passage, they will see each other Light to fluorescent beads"

"180 meters is long enough, and we can tell whether there is any large mechanism that we can't see with the naked eye, or be deceived by vision."

"45 meters, the sound can also be transmitted."

The double-headed shark nodded. This is a good idea. Although it was a waste of time to go back, the road behind has been carefully explored once, and there is no danger. Time is not important now, and it can be wasted.

"I agree with this approach."

"I agree."

"I have no opinion."

Everyone agreed, the three of them took the fluorescent beads from the double-headed shark's hand, and tapped lightly on the wall, and the originally black fluorescent beads glowed faintly.

In the live broadcast room, a group of water friends are eating melon seeds and chatting

"Good guy, this one looks like a big and three rough, but his brain is turning fast."

"Otherwise, do you think that the one who can become the boss is a fool?"

"By the way, I haven't understood what I'm playing this time?",

"Hee hee, I didn't understand either."

"You said, is this passage endless? The soul slayers want to trap them to death here?"

"Laughing, do you know what you are talking about upstairs?"

"There is no end? Haha, I laughed so hard."

"I think it might be a large institution, but they are actually in a circular building."

"Yes, I think the one upstairs is very reasonable. When the arc is large enough, the arc will not be obvious"

"And, there is one more thing, you didn't realize that there is no light source in the tunnel"

"What does having no light source have to do with this?"

"Stupid? Without a light source, many visual traps can be completed, such as some slight arcs or moving mechanisms in the distance, but you can't see them."

"I see!!!"

·······

The four set off again, this time at a much faster speed, after all, there is no need to explore the way.

With such a moving speed, even if there is any special mechanism in the passage, it is impossible to activate it silently.

The distance of 45 meters was fleeting, and the double-headed shark kept paying attention to the fluorescent beads behind it.

"Okay, here I am, you continue."

The double-headed shark stopped, and squeezed his left hand into an orchid finger, exposing the fluorescent beads as much as possible.

His eyes were fixed on the fluorescent bead at the first point, and likewise, there was no change there.

The right hand quickly tapped on the wall and the ground without any mechanism, just like the previous inspection.

Soon, the tiger shark also reached the predetermined distance, and the fluorescent beads on the hands of the double-headed shark could only be seen faintly, and even the hand holding the fluorescent beads could hardly be distinguished.

"I'm here, you go on"

The tiger shark stopped and spoke loudly. The double-headed shark 40 meters away could hear it clearly.

Even if you close your eyes, you will choose to open one eye and close the other eye.

He was afraid that if he was careless, the fluorescent beads would disappear.

40+40+40，已经是120米了，120米内没有机关。

In fact, from the very beginning, the double-headed shark didn't think that there might be any mechanism.

Cement, and it is still such a large cement building, if there is a mechanism, it can only be a large mechanism.

This kind of large-scale institution, not to mention Daliang country, even the most technologically advanced free country can't be silent, even if there is no sound, there will be vibrations to some extent.

And the resonance effect of this kind of large-scale physical building is quite obvious, and a little bit of weak vibration can be transmitted very far.

However, his hand kept touching the wall, but he didn't feel this kind of vibration.

However, just now, he did not object to this attempt.

After all, everything is just speculation before it is confirmed.

After a while, a vague voice came from behind. Because the voice was too far away and echoed through the passage, it became indistinct, and it could only be vaguely heard that it was someone talking.

The double-headed shark narrowed its eyes, 40+40+40+40,160, [-] meters, still no problem.

Sure enough, my guess was right, this is really a fucking straight road.

The double-headed shark felt cold sweat pouring out of his forehead. Guessing is guessing, reality is reality.

This is really outrageous, how is it possible?

------------

60. Run fast and crash first

The brain of the two-headed shark started to run wild.

Since the people behind did not speak, it must mean that there is no arc.

This section of passage can be said to be randomly intercepted by us, and it is the same for the previous passage.

After all, the ecstasy certainly can't decide when we start exploring, or where we want to measure.

After all, there may be various variables whether everyone moves forward or backward.

Therefore, after ruling out all the impossibilities, the greatest possibility is that the four of us are really located in a passage of unknown length.

But there is another question, if this passage is very long, how did the four of us get here?

It shouldn't be possible to rely on manpower, but to use special vehicles for transportation?

Or is it possible to enter and exit freely somewhere in the passage, but because of light and structural problems, everyone has not found it yet?

Just as the double-headed shark was thinking, footsteps came from behind him again.

The double-headed shark stopped thinking and looked back.

There is a light source approaching in the distance, and the three dark figures are exactly my three partners.

When the three approached and saw the faces of the three, the luck in the double-headed shark's heart completely disappeared.

"It's a straight line, right?"

"Yes, it's a straight line."

Tiger Shark nodded and said, without disappointment or surprise in his tone, it seems that he had expected it.

Seeing that the atmosphere in the team was not right, the double-headed shark said

"Now let's change to another test method. We run at full speed to see if we can find something strange about this passage."
