"Interesting?"

Before the war, when I came here for sightseeing, the entire underwater park was air-conditioned. After all, before 'that war', people's technological level reached the highest peak of mankind.

As for the source of the air here now......

"Although I don't know how to solve the air problem here before the war, the air here now is provided by that 'net'." Ling said, pointing to the sky wall.

"You look up closely, and under the wall of the sky, there is a criss-crossing net, which covers the entire protective ring like the wall, and that net is made up of many hollow pipes, and every other section, there are air outlets.

Seven of the nine circles, each with an air 'pumping/converting/purifying' device.

The air produced by the plants on the seabed is first 'pumped' and the air entering the seabed through the 'spiral tunnel', and then the air is 'purified' to a purity that can be breathed naturally by people through the 'purifier', and then emitted into the circle through the net for people to breathe.

There are two ways to get in and out of the ninth lap: the Ocean Submarine and the 'Spiral Tunnel' that goes straight to the surface.

Spiral Tunnel: It is a passage that can be driven by three 'capsule trams' that lead directly to the sea outside the main circle and the other two small circles, but it is limited to five people at a time, and the weight limit is 800KG. The time from the surface to the bottom of the sea is forty minutes, and the power source is electricity.

Because the entrance and exit are fixed, time-consuming and inconvenient, it is rarely used for passage, and is mostly used for 'extracting' air from the sea.

People still rely mainly on ocean submarines for travel.

Ocean submarines are divided into 'transport' and 'sightseeing'.

Transport submarines are "military submarines" left over from the "war" and are generally used to transport and exchange animals and plants, and to receive "executors" or "proposers". It only stays in the central circle of the nine circles, and is not allowed to be used by the general public.

The sightseeing submarine is a fully transparent 'capsule-type' submarine, which is relatively small, and the maximum carrying capacity of a submarine is ten people. It can be driven freely on each lap of the nine laps and on the bottom of the sea, and is also used for searching and hunting on the bottom of the sea. There are stops at all entrances and exits of the nine circles, and residents of the nine circles are required to show their 'biometric certificates' to board the boat.

There are five fixed 'receiving platforms' on the sea surface of the Nine Circles, and outsiders need to apply one week in advance to indicate which 'receiving platform' they are in, and after receiving the application, the Nine Circles will send corresponding submarines to meet them.

That's what I know about lap nine.

So, as long as it weren't for the problems with those three special circles and this central main circle, the nine circles would be fine. ”

"Should we praise human wisdom or hate human wisdom?" Zhuge Xun sighed.

"If you don't know, then I don't know."

"After dawn, shall we go to a few other circles to have a look?"

"Well, it's already here anyway. But then again, here in the Nine Circles, I'm still really ......" Ling remembered what had happened there in the Fourth Civilian Zone.

"Or else...... Someone. Zhuge Xun suddenly felt an aura.

Ling also felt it, and the two of them moved their bodies to the dark place at the same time, and then lay on the ground to observe the surrounding movements.

At this time, a patrol of about five people walked from a distance to this side, and then stopped to rest at a bench not far in front of them.

The location of Ling and Zhuge Xun was a dead end for the team, and the two of them could clearly see the team and hear them at the same time.

Then I heard a soldier say.

"What the hell are we looking for? I've been looking for it all night. ”

"If you want to find it, what so much nonsense!" The man in charge of the group said. However, he could hear that his emotions were also unstable.

"Captain, let's take a break. The view here is good, we can find anyone in time, you see, we have been looking non-stop for four hours since we received the order, and we still don't know what to look for, can you tell the brothers. Another soldier said.

"You think I'm going to look for it. I also know that everyone is working hard, but it can't be helped, it's too important. Well, let's rest for twenty minutes first, and it's best if the other teams can find it, so that the brothers can't work hard. ”

"It's better to be our captain!" As soon as the others heard that they could rest, they all found a place to sit nearby.

"Captain, tell us about it."

"Well, anyway, I can't say anything." The captain said, taking a sip of water from the kettle.

"Six hours ago, just before we left, someone had sneaked into the office of the ring owner, Hlebosch, and stole something. I heard that that thing is very important to the circle owner.

Then the order we received was given, and all the entrances to the opposite side were sealed, and that thing must be retrieved no matter what. The claim that our circle is threatened by an undersea earthquake is also to prevent people from entering and exiting. ”

"What the hell is it? Do you know? ”

"I don't know what it is, I just know that it's a box, the box is a special material, with this detector, if the box is nearby, you can sense it." The captain showed everyone the detector in his hand.

"What do you say that people can go to the owner of the circle and steal something? It must not be from our nine circles, it must be someone from outside. ”

"But the problem is that after the circle owner found out that he had lost something, he immediately checked all the people from the nine circles of outsiders one by one, but he didn't find it, so he asked us to search like this. Maybe it was hidden by someone who stole it. ”

"I don't believe that our people in the Nine Circles would do such a thing."

"I don't believe it either!"

"We don't believe it, but the problem is that the owner of the circle only left for a while, and then found that the thing was gone, and I heard that the place where the thing is usually put is very secret, and only the owner of the circle knows it, if it is an outsider who wants to steal it, I am afraid that he will not be able to find where the thing is.

So the best solution now is to find the thing that was lost. ”

"It won't have been taken away."

"No, because I heard from my superiors, after the owner of the circle found that the things were gone, he immediately blocked all the entrances and exits, unless the person who stole the things would teleport, otherwise it would be impossible to take the things out of the nine circles."

"I see, we're not looking for someone who stole things now, we're looking for things, right? Because the thief knew that he couldn't escape, he hid it first, and when we didn't look for it, he was running away. ”

"I'll go, you kid, you're smart."

"Haha, I didn't learn it from the captain."

"Okay, there you have it. Okay, everyone has rested enough, let's keep looking. ”

A group of men got up and continued to look for them.

"The Lord of the Nine Circles lost something?"

After the group walked away, Ling and Zhuge Xun sat up.

"And the stealer is still a master. You don't want to get involved in this again, do you? Zhuge Xun asked.
