Doomsday Yuan

None of them were interested in chatting, so after Luo Wen'an answered Xu Song's question, they became quiet again.

The smell in the sewage pipes can't be called fresh, but fortunately, the shelter was established not long ago, and the weather is weirdly cold, but it's not unbearable.

According to the results of Xiaoshu's exploration yesterday, the two drew a simple schematic diagram of the underground water pipeline in the shelter.Now, this picture is completely recorded in Xu Song's mind, and Yue Song's memory is not bad. Although he can't memorize it all at once like Xu Song, if he only remembers the road to the laboratory, he still can't remember it. any questions.

At this time, the twins and Xiao Shu were left at home.After thinking about exposing the children, possible dangers in the laboratory, and "warning", the two decided that it would be better not to take risks and take them with them.

After all, the child is too young and has great limitations in mobility.If it was just a pre-reconnaissance operation, the two would not mind taking them with them, but the safety of the two children is still the most important thing for this infiltration operation that may encounter danger at any time.

The way to sneak in is very long, and there will be various forks in the middle. Fortunately, at this time, there are very few people who go to WC conveniently...

"This way." Walking through the underground pipeline of the main road, Yue Zheng was the first to find the oblique underground pipeline leading to the laboratory.The shape of this pipeline is quite strange. It leads to the sea at one end, and the pipeline terminal of the entire refuge is gathered at the other end. The pipeline in the laboratory is also connected to it at a deeper position.

There is no starry sky in the underground world, and even the air seems to be frozen. Everyone wears at least one mask on their faces, and follows Yue Zheng cautiously with an ugly expression.

After walking for another half an hour, finally, in a relatively hidden dark place, several people found the pipeline leading directly to the laboratory.

"Walk for a while and we'll be there." Seeing that the pipeline was indeed as shown on the diagram, Yue Zheng breathed a sigh of relief, and took the lead in sneaking in carefully.

Luo Wen'an and the others silently wiped off their sweat, their hearts couldn't help getting excited.Although I don't know if Liu Shishi is inside or not, but now at least I can see hope is in front of me!

Going up the slope, the flashlight swayed on the wet wall from time to time, and only the sound of my own footsteps could be heard in the passage. Since the drainage system here is newly built, no creatures have been attracted to live at this moment, let alone Discover the existence of mutant creatures...

"Wait!" Yue Zheng's footsteps suddenly stopped, and he raised his hand as a signal.

"What's the matter?" Several people were nervous for a moment, desperately looking towards the dark front, but they couldn't see anything wrong.

"There are monitoring equipment." It's not a camera—of course, even if the refuge will install surveillance in this location, you definitely don't want to face the unappetizing "scene" here every day.

Several people tensed up.

Xu Song and Luo Wen'an didn't have the slightest doubt. Xu Song knew that Yue Zheng could see things in the dark like daylight, and he trusted him unconditionally, so he would not doubt any of his judgments.Luo Wen'an and Su Tanji subconsciously obeyed his orders when they were traveling together, so they obeyed his words reflexively when their future was unknown.

But Han Yue and Liu Xu were a little puzzled and suspicious. It was so dark here, and they didn't have any special equipment. How did he know there would be surveillance equipment here?Or... is there really an ambush ahead?Did Yue Zheng and the others deliberately lure the two of them here?

Before they figured out one, two, three, Yue Zheng had roughly figured out what that thing was from a relatively safe position.It should be a sound wave device, perhaps not to prevent thieves, but to prevent some mutated animals from breaking into the underground drainage system, so as to prevent them from sneaking into the laboratory from the sewer to destroy the equipment.

"It's a sound wave device." The current distance has not yet reached the range that the device can detect. Yue Zheng once again thanked himself for the power of his supernatural power. Wearing it close to his body, the warm feeling gradually gathers on his body every day. Now, he clearly feels that the visual range and clarity of his night vision are almost the same as that of ordinary people during the day.

"Sound wave? Can it be destroyed at such a distance?" Xu Song looked towards the dark front. He didn't know where the equipment was, but he knew it was just ahead.

"Even if it can attack from a distance, I'm afraid that the sound of piercing the sky will be recorded by it, which will alert the higher authorities." Yue Zheng didn't dare to take risks, they only had this chance, and they must not be interrupted or destroyed by any mistake.

"Will you walk more lightly?" Luo Wen'an, who was following behind, also quickly came up with an idea.

"I remember that your fireball made no sound when it was flying, right?" Yue Zheng asked suddenly.

"It seems, but I can't see where that thing is." Xu Song nodded. The fire he fired was very strange. It didn't make a burning sound like ordinary flames, and it only made a sound when it hit the target.

"Will there be a sound when that thing is burned?" Su Tanji quickly reminded.

"If the temperature is high enough, it can be burned immediately, and as long as the blow is successful, it will not cause problems for the time being." Yue Zheng made a decision, "Come on, I will show you the direction.

Xu Song stood in front of Yue Zheng, following the direction in which his hand was raised, estimating the location of the device.

My back is completely attached to his arms, which makes people feel warm and at ease.All the apprehension I had before was gone now.

Raising his hand, a red fire ball jumped out of his palm, and as he turned with his thoughts, the fire light compressed, kneaded, and transformed, and gradually, it turned into a fire ball that was only one-third the size of its original size.

The red light greeted the faces of the two, dyeing them with a faint red.

Han Yue and Liu Xu, who were at the end of the group, also forgot their entanglement before, and looked at the docile fiery red ball with some surprise.

Following the direction pointed by Yue Zheng, the fireball flew away from his hand, following Xu Song's thoughts, fluttering and flickering, without causing half a sound, and directly focused on the target.

With a "crack, bang", the instrument was directly burned to ashes, leaving only a few sparks from a wire.

"Will they find out that this device has been scrapped?"

"I don't think so for the time being." Yue Zheng shook his head, "If I'm not wrong, this kind of thing will only call the police after receiving a sound exceeding a certain decibel. The sound below a certain decibel will not attract their attention. of."

"Let me just say, the sewer is under the alarm, how many times do we have to flush it every day? If they have to come down to check every time, wouldn't they be so busy every day?" Su Tanji spread his hands at several people.

"Go on, if there's anything wrong, immediately retreat the same way." Yue Zheng also meant the same thing, so he decided to get rid of that thing directly.He estimated that this thing should be because the people in the laboratory had suffered from the mutant creatures in the sewer, so they pressed this thing at the beginning of the establishment of the laboratory, just in case.

But this thing is not the same as camera surveillance after all, no one will stare at it 24 hours a day.

At a corner not far ahead, there was indeed a similar device, which was passed by a small fireball from Xu Song, carbonized again, leaving only a little slag, which fell into the sewage, and slowly moved towards the sea along the waterway .

The construction of the sewage pipeline in the laboratory is very strange. It does not lead directly to the main pipeline, but there are several bends in the middle, and there are even forks.I don't know what those fork roads are for. From the outside, Xiaoshu can only detect those bends and turn for a while, then they end, and they don't lead to any other direction.

Yue Zheng could not help being deceitful, so he led the crowd in the right direction.

There are indeed frauds in the forks, and all kinds of traps are basically arranged in those places.After all, the pipe directly leading to the research room was used to drain sewage. They thought they could just use sound waves to monitor it just in case, so they didn't make any extra things.

These traps were originally used to prevent people with supernatural abilities from sneaking in and mutant creatures to come in by mistake, but who would have thought of it?Someone actually explored the panorama of the sewer from the soil on the outside of the pipe, and found the right road without detours at half the road?

Once those traps are triggered, they will discharge a large amount of poisonous and corrosive substances from the bottom room of the laboratory directly into the sewer just like when the sound wave detector is triggered, which can directly destroy the creatures that enter by mistake.Yue Zheng and the others escaped unharmed because of their lack of adventurous spirit, and Xu Song's little fireball also took advantage of not being able to make a sound, let alone triggering those devices. I have to say that they were quite lucky.

After twisting and turning, it didn't take long for everyone to arrive directly under the laboratory.

"How to get in? It won't be their toilet as soon as you climb out..." The smell in the sewage pipe has already made several people dizzy. If they are asked to climb out of the toilet...let them vomit for a while.

"No." Yue Zheng shook his head, and after confirming that there was no device near the access passage, he climbed in first.

Everyone had no choice but to bite the bullet and follow. Han Yue, as the only woman in the team, nearly cried when she found out that she had to climb the pipe after walking for more than an hour.

Fortunately, a few people went up and found that this place is not like the pipes below, but a relatively flat place. Except for the sewage discharge point on one side, there is a strange device on the other side. I don’t know what is contained in it. From the outside, it looks like a box that can be tilted down at any time, and the contents can be poured into the sewage tank.On the other side of the room there is a hanging ladder that leads up to it.

"What's here?" The smell here has become much better, and Liu Xu is also in the mood to ask questions at this time.

"It's not a good thing." Yue Zheng, whose sense of smell has also evolved a lot, frowned slightly. The thing was well sealed, but he could still smell a smell from it-a smell that can only be found in laboratories, chemical industry, etc. The smell that only exists in the factory seems to be similar to some kind of strong acid.

Looking at the sewage outlet that the thing was facing, he decided that it would be better not to reveal his guess, otherwise, no one would dare to go out from here in a while.

Looking at Yue Zheng suspiciously, Liu Xu wanted to ask again, but was pulled away by Han Yue beside him.
