Lao Miao glanced at the place Wang Xiaotian was pointing to, and said, "There is a recycling disposal center." All household garbage and sewage will be concentrated there for harmless disposal. ”

"Huh?" Wang Xiaotian was stunned for a moment and said, "Sewage water flows to a low place, shouldn't all the sewage be concentrated at the bottom of the base for disposal?"

Lao Miao shook his head and said: "If it is concentrated at the bottom, it is very convenient to collect it, but after the disposal of the substance, there is no way to discharge it smoothly, and it is not convenient to discharge it from there." ”

Wang Xiaotian was puzzled, "Why?"

Lao Miao explained: "The recycling and disposal center will dispose of domestic garbage and sewage harmlessly. After the disposal is completed, it will be divided into several categories and continue to be processed. A type of purified and reusable resource, including clean water, fibers, metals and plastics, is piped to the warehouse. ”

"The other category is non-recyclable solid waste, such as manure and sludge, which can be used as plant fertilizer, fermented and sent to specialized plant factories and islands for use. There is also a category of sewage that has no recycling value, but is not harmful, and will be discharged into seawater. ”

"If the opening of the sewage channel is placed deep underground, it must be discharged with a special sewage pump and a large amount of energy. Moreover, the channel is exposed to extreme water pressure and is prone to collapse and seawater inflow. ”

"The base is designed and built according to the standard of normal operation for 10,000 years, and all the details must serve this standard. Therefore, considering the cost of use and maintenance as well as the service life, it is the best choice to place the recycling and disposal center at a high place and open the sewage outlet above the sea surface. ”

Lao Miao said again: "Your guess is very reasonable. The recycling center has always been unmanned and autonomous. If the defenders were hiding there and no one was looking, they wouldn't have been able to find out. I'll let people go over and see it now. ”

Wang Xiaotian said: "Wait a minute. He pointed to a few other unattended places on the hologram and said, "Here, here, these places better be checked." ”

Lao Miao nodded and said, "With so many places, it's not easy to allocate manpower." Hong Qingchen, you take a few of them to the place that Xiaotian said just now. ”

Hong Qingchen nodded in response, turned around and beckoned all the workers to leave.

Wang Xiaotian said: "Let's also go and see the recycling center." ”

Lao Miao nodded, and then took Wang Xiaotian to the corner of the mecha hangar, entered the mecha special elevator, and rose directly to the vicinity of the exit.

Walking out of the elevator, Wang Xiaotian saw a huge platform. There are tens of thousands of square meters, and the most important thing is that there is an unobstructed view of the emptiness. The exit of the base is on a special lifting platform on the side of the platform.

More than a dozen security personnel, divided into two groups, guarded the elevator at the exit and the elevator entrance to the base. In addition to the security personnel, the entire platform is covered with surveillance cameras, not to mention people, not even a fly has nowhere to hide.

Wang Xiaotian glanced at it hurriedly and immediately remembered the location of all the surveillance cameras, as well as the installation method. Then, he said to Lao Miao: "It seems that the traitor did not come here. Let's take a look at the recycling center. ”

Lao Miao took him to an inconspicuous corner of the platform. It looks like the rest of the place, but if you look closely, you can see that there is an inconspicuous circle twenty centimeters in diameter on the walls.

Lao Miao stretched out his hand to make a circle and pressed it, and after a slight sound of metal rubbing, the wall in the circle area quickly retreated, and a metal pole stretched out from it, and the end was bent into a triangle.

Lao Miao stretched out his hand to hold the flat triangle, twisted it half a circle to the left, then pulled out ten centimeters outward, then twisted one and a half circles to the right, then pulled out ten centimeters outward, then twisted it to the right, pulled out ten centimeters, and finally twisted three times to the left, and pushed all the metal rods into the hole.

Wang Xiaotian heard that there was a low movement of machinery running in the wall, and then, the wall next to where Lao Miao was standing suddenly cracked a big hole backwards, with a height and width of more than ten meters.

Lao Miao was the first to walk in, and Wang Xiaotian also followed.

The cave is bright and wide, and the two Defender mechs walk side by side without feeling crowded.

Lao Miao said as he walked: "This place is automatic. Considering that once you need to get here, there must be no motivation for the entire base. Therefore, the way to open the door here is to use mechanical encryption. ”

Hearing him say this, Wang Xiaotian immediately thought that he was holding the long metal rod with a triangular end, twisting left and right to pull out and propulsion, it seemed that he was entering a mechanical password by doing that.

This design is quite good, similar to the safe of the old era, if you don't know the password, such a huge device, such a thick wall, it is impossible to forcibly break it. The only problem is that the password is fixed and there is no way to change it.

After walking for about 20 meters, Wang Xiaotian's eyes suddenly brightened.

Underneath them, there are countless thick pipes, arranged in an orderly manner, which are connected into a huge boxy building, and then there are huge devices from the building that are connected to the sides of the building. There are huge centrifuges, huge compression pumps, huge screening machines, and many huge pieces of equipment that Wang Xiaotian can't name.

Wang Xiaotian took a look at these huge pieces of equipment and asked, "Is there only one passage in the recycling and disposal center?"

Lao Miao shook his head and said, "Of course, it can't be only this passage. There are four passages in and out of here, one of which is underneath and two on the left and right. The following one is the widest for transporting machinery and equipment. The left and right sides are maintenance lanes, which are convenient for personnel and tools to enter and exit. ”

Wang Xiaotian sighed and said, "With so many passages and such a big place, how can you find a trace of a traitor?"

Lao Miao said: "I have already sent a message, and a helper will come over soon." When they came, they searched together from all four directions. ”

Wang Xiaotian was shocked. His original plan was to take advantage of the absence of others to come, get rid of the old seedlings, and go to the defenders himself, if there are too many people. His plan went bankrupt.

Wang Xiaotian nodded slightly while observing below. Suddenly, he pointed to a huge centrifugal pump and said, "There it is!" I saw a huge shadow just now, and shook it for a moment. ”

Lao Miao immediately looked in the direction pointed by Wang Xiaotian, but did not find any movement. He said suspiciously, "Are you sure? Why didn't I see it?"

Wang Xiaotian said: "Of course I'm sure, I can see it clearly." ”

Lao Miao was still not at ease, and said: "Let's wait for a while, they will come soon, and when they come, we will look for it again like pulling a net together." You can rest assured that as long as it is here, it will never be able to run. ”

Wang Xiaotian said anxiously: "I'm not at ease at all. As you just said, there are four passages here, and what if it notices that a lot of people are coming and flees in the chaos? Who knows which passage it came in from, and which passage it will escape from? Without further ado, let's go and find it. ”

Lao Miao thought for a while and didn't speak. Because whatever he said at this time, Wang Xiaotian had reason to refute him.

Seeing that he didn't speak, Wang Xiaotian immediately said: "I don't care so much, if you don't go, I'll go." With that, Wang Xiaotian flew directly and jumped down.

Lao Miao hurriedly raised his wrist and shouted into the communicator on his wrist: "Recycling disposal center, a few security personnel will come immediately." Then he jumped off.

However, Lao Miao was stunned when he went down, because he looked left and right, and he couldn't find Wang Xiaotian's shadow. He chased after him in the direction indicated by Wang Xiaotian before, and after chasing for a while, he immediately stopped. Immediately after, he leaped to his feet and landed on a pipe high above, from above

Look carefully.

After searching for a long time, he didn't even find a single clue about Wang Xiaotian and the defenders. Lao Miao immediately realized that he had been fooled!

He immediately raised his arm and shouted into the communicator: "Close all exits from the recycling center, no one is allowed to open them!"

Just one minute before Lao Miao gave the order to close the exit, there was a wave of security personnel in the maintenance passage on the left side of the recycling disposal center, who had just opened the entrance of the passage and came in. The first of them had not yet stepped out of the aisle.

Hearing Lao Miao's order, they immediately looked at each other. However, they reacted quickly and immediately turned around and retreated in an orderly manner.

Wang Xiaotian, who was hiding in the corner, sighed in his heart when he saw this. Originally, he wanted to wait for these people to come, so he chose a target of similar height and size, quietly followed him, looked for an opportunity to knock him unconscious, and then changed into his clothes and went out.

Unexpectedly, Lao Miao immediately thought that Wang Xiaotian might use the trick of mixing up the pearls, so he decisively asked the security personnel to withdraw. In this way, Wang Xiaotian has no chance to be confused.

However, Wang Xiaotian did not take the risk of rushing out. He knew very well that rushing out now, although he could rush out before these security personnel stopped him, it also completely alarmed Lao Miao and Xuanying. As soon as these two people made a move, he never had a chance to get out of the base.

However, if you don't take advantage of this opportunity to go out, it will be difficult to find another opportunity. Wang Xiaotian's brain teaser was in a hurry, and he immediately had a way. By this time, several security personnel had already begun to move out.

When the last security guard walked out of the gate, Wang Xiaotian took out a metal hose from the original crystal space. This hose was the half-tentacle of the robotic octopus he encountered in his shelter in the Dragon's lair. He got some at the time and put them in the Primordial Crystal Space.

Wang Xiaotian quickly threw the half-voluted tentacle of the machine octopus towards the door. The half-tentacle spun and flew silently towards the doorway.

The door was closing, and on the side of the half-truncated tentacle, there were many suction cups, which were attached to the side of the gate at once. Due to the very thick door, the security personnel did not see the tentacle from the outside.

The door closed, and half of the tentacles slipped between the door and the door frame, leaving only a few centimeters on the outside. Due to the half-cut tentacles stuffed in, the door was not closed properly, and there was no trace of what should have been closed after being closed, but now a slight gap appeared. If the security personnel outside were careful enough, they should be able to tell.

Therefore, Wang Xiaotian did not act immediately, but waited patiently for a few minutes, and when he saw that there was nothing abnormal, he quickly entered the passage, crept to the door, put his ear on the door, and listened carefully for a moment to confirm that there was no movement outside.

He crouched down, reached out and grabbed the half-tentacle, and entered the Force, trying to manipulate the half-tentacle. However, the material of the half-cut tentacle is not the Force metals such as Ming Copper, Ser Silver, and Xuanjin, so there is no way to conduct the Force. He tried for half a day without success.

Wang Xiaotian had no choice but to take out his stabbing sword and insert it along the crack of the door. He guessed that no matter how many ways there were to open the door, there was only one way to hold the door and the door frame together, and that was with a latch. So, all you need to do is cut the latch to open the door.

Just now, Lao Miao also said that in order to prevent the door from being opened after the power failure of the base, all the doors are mechanically controlled and there are no electronic devices. Wang Xiaotian was worried that the alarm would be triggered.

He quickly cut the latch with his bayonet, then carefully tried to pull the door a little. The heavy stone door silently opened a crack, and Wang Xiaotian looked out through the crack in the door to confirm that there was no one around.

Wang Xiaotian was just about to open the door and go out, when he suddenly felt something quietly approaching. Moreover, they are full of hostility towards him, and seem to want to kill him as soon as possible!

The cold hairs on Wang Xiaotian's back stood up! Who the hell is here? Old Miao? Why does he have so much hatred?
