"What's going on?"

Ren Yuan looked at the scene in front of him, and his face became gloomy.

"I don't know, it's better to know what's going on." The coyote brigade members who stayed at the funeral home said quite embarrassedly

"Did you find anything unusual before?" Yu Qian hurriedly played the round

"Yes, but," the team member said after a pause, "it's too fast, it's too late for us to hear the sound." Almost in the space of a dozen seconds, it became like this. ”

In the morning, when Yu Qian and Ren Yuan were preparing equipment to explore the cracks excavated last night, the remaining members of the Coyote Brigade informed them of a very unacceptable news.

Just now, the tentacles in the crevice suddenly seemed to have been dried by the air, and they clung to the rock wall one by one, as if they were covered with a layer of shiny scales. The underground river deep inside the cavern also lost its light and became pitch black. By the time the two of them hurried over, it was already too late.

"I knew I could, I should have done last night..."Yu Qian said helplessly

"Forget it, it was too late last night." Ren Yuan shook his head, "Since the other party has prepared manpower to interfere with our investigation, it can be seen that the other party has long expected that we will find out." We were late from the start, and the time wasn't worse than the hours we had last night. ”

"What do we do now? Do you want to go down and have a look? Yu Qian asked

"It's still going to be watched, if you don't catch up with the firefighting, won't you deal with the post-disaster scene?" Ren Yuan sighed, "Just now, don't wait for the night." ”

"But the preparations are not ready, and." Yu Qian raised his thumb and pointed outside, "Now there are so many ordinary people outside. ”

In order not to interfere with the normal operation of the funeral home, the coyote brigade set up a shed covered by a three-color PVC tarpaulin overnight and surrounded the two crematoriums. Although the sight is isolated, but only a curtain is separated by a bustling crowd, as well as crematorium workers at work, and the secrecy effect is really not good.

"If the situation doesn't change, of course it's better to wait after work. Otherwise, what happened during the exploration process is not a joke. Ren Yuan shrugged his shoulders and said, "But now, the Advent Sect has obviously withdrawn first. Since that's the case, there's nothing to worry about, and I don't think any monsters will pop up, so I might be able to dig up some clues while I look up now. ”

Yu Qian thought about it, and felt that what he said made sense, so he declared the course of action to the ministry through Jiang Ziwen, and waited for the materials to be delivered on the spot.

"Hey, when will the order to open up the authority be issued, it's too troublesome to report everything." Ren Yuan sat down cross-legged and complained boredly

"Will the above really give you permission?" Yu Qian remembered the policy on opening special privileges he had seen in the manual, and was suspicious, "If it's really like what you said, this special privilege is inevitably too high, right?" ”

"You don't understand that, do you? Isn't it always the magic weapon of our party to decentralize policies to the grassroots level, give full play to flexible and autonomous tactical thinking, grasp the overall dynamics, and endow front-line soldiers with thinking at the level of strategic campaigns. What's wrong with that? ”

"It's two different things, okay." Yu Qian didn't want to have anything to do with him in this regard, and this was not a problem for him to worry about, so he changed the topic and said, "We're doing this here, and we won't be discovered by the outside people, right?" ”

"You think too much, you can rest assured that I will do things, it's not that complicated."

Soon the instructions from above were issued, and a special communication fiber optic cable with a core of 2,500 meters was sent in. After connecting the communication equipment, Ren Yuan took the camera and the communicator and prepared to go down.

The tentacle dry matter clinging to the rock wall has been partially sampled and sent to the laboratory. Last time, Ren Yuan didn't have much interference from these tentacles, and this time these tentacles have turned into dried squid shreds, so there is no hindrance. It's just a faint, earthy smell similar to river products.

Ren Yuan went down to the bottom and found that the destruction of the Advent Party here was quite complete, and the underground river that was still glowing with a faint glow had completely lost its luster and exuded a smell of corruption. The plankton that grew in the water system seemed to have died overnight, and the entire water vein suddenly became alive and dead.

Thick dark gray scales appeared around Ren Yuan's body. He stripped naked, and two rows of twelve pairs of gill clefts sprouted from his front chest for underwater breathing. The fingers and toes are greatly elongated to form the connected webbed membranes, and the back and knee and elbow joints have several wing fins. In less than a dozen minutes, Ren Yuan made the last preparations before going into the water, fastened his communication helmet and silently plunged into the underground dark river.

As soon as he got out of the water, Ren Yuan felt a huge pressure. Although he had taken into account the low oxygen content of the underground water system and prepared a large number of gill clefts close to the lungs, he never expected that the oxygen content in the water would be as low as possible. No matter how hard he squeezed through the gill cleft in his chest, he couldn't squeeze out enough oxygen for him to breathe.

Now we finally know why, in just one night, this water vein completely lost its vitality, and the microorganisms died. All the oxygen in the entire vein of the water was rapidly drained, and only a few anaerobic organisms were left. As a last resort, Ren Yuan began to ferment the sugar in his body to supply energy.

"Did you get it? This is Zero, the oxygen in the water has been drained, and it is not known how the other party did it for the time being. "Ren Yuan conveyed the observed information through the fiber optic cable" is continuing to dive, and no signs of life have been found yet, over. ”

"Number 1 received, number zero is vigilant, and will reply at any time if there is a situation." Yu Qian stared at the sonar images coming from underwater, and could see nothing but the rugged and complex rock formations.

Because he didn't want to be a target underwater, Ren Yuan didn't carry any lighting equipment, but relied on hearing and smelling to sense the situation in the water. The sonar on his head constantly emitted infrasound waves, and Ren Yuan relied on his ears and skin to receive these feedback sound waves to understand the situation around him.

The underground water system was much simpler than he had imagined, with only one main trunk and few tributaries. Last night, he took a brief look at the water flow, and basically determined that this water vein itself should be a small tributary, and the source is not surprisingly a suburban peak. But now this vein has not only been drained of oxygen, but has also stopped flowing. If his prediction was right, someone should have blocked the other end.

Ren Yuan dragged downstream for two hours, and finally found the place where the water vein was blocked. It was a long, narrow hole only a few meters wide, and judging from the information fed back by the sonar, the opposite side was very decisive. It is a kind of secretion similar to limestone that completely blocks the entire passage.

Reaching out and knocking, Ren Yuan gave up his intention to smash it. In terms of the difficulty of excavation, it is easier to dig another passage from the side than to break up the whole piece of coagulated secretions. The other party did not shy away from showing this reality in front of him, clearly telling him that the purpose was to delay time.

Not to mention that there are no conditions for blasting in this environment, even if you put your heart into it, the other party can block this opening overnight. But the disaster department is not able to dig it up in a few days, and when the treatment is over, the daylily will be cold. Finding the right position, Ren Yuan opened his mouth to gnaw a piece of the secretion, swinging his legs and swimming back again.

Ren Yuan, who returned to the surface, shook off a water stain and spit out the fragments in his mouth

"Take it for a test and see if you can find anything."

Yu Qian watched the members of the Coyote Brigade carefully take over the fragments, and couldn't help but complain, "What can this test find?" ”

"The test didn't show anything, it was like running to lick someone else's finished ice cream stick." Ren Yuan couldn't help laughing at himself, "We can imagine what the other party will look like when they eat ice cream while snorting the wood chips, and at the same time comfort ourselves once the other party eats it cleanly?" ”

"Can you please stop saying it so disgustingly."

"Okay, let's talk about something else." Ren Yuan dried his body with a bath towel and said, "Before we talk, I think let's go back first, this is not the place to talk about things." ”

Since just now, the families of the deceased, who are extremely bored, have been staring at this small world surrounded by tarpaulins and pointing. They all speculated about what happened to the two boilers, and if it weren't for the security guards guarding outside, some people would have been tempted to come over and take a look at the cloth foot probe.

The two packed up their duties, left the rest of the aftermath work to the coyote brigade, and drove home.

"What's going on next?" While driving, Yu Qian asked Ren Yuan, who was sitting in the co-pilot

"It's nothing, now it seems that it is a secret passage built by the Advent Sect relying on underground water veins to facilitate the secret transportation of corpses..."Ren Yuan briefly introduced the situation

"But now it seems that the other party has given up on his own initiative, and a clue we finally dug up has been broken again."

"Not really, right?" Yu Qian thought for a moment and said, "We can also start with Wu Qing's family and colleagues, including the cremator named Zhao Heigou, which is also a clue. ”

"It's useless, it's useless." Ren Yuan shook his head and said, "These are clues, but they can't touch the core of the Advent Sect. You don't know them, just take the Zoroastrian sect ten years ago, their organization is like grapes. "It looks like a lot of fruit, but it's all an illusion. The only thing that connects the fruit to the vine is a thin twig, and if you cut that one, it doesn't matter how big a bunch of grapes you pick, you can't even affect another bunch of grapes. Each small organization is independent. ”

"Okay, then let's focus on Meng Wei next?"

"Meng Wei wants to investigate, but if the ministry can give me open permission, I have another plan." Ren Yuan said, "Let's not talk about this for a while, what do you think about how the Advent Sect used that underground water vein to transport corpses?" ”

"This... I can't guess, you've been dealing with the Advent for so long, you must be able to guess it, right? Yu Qian knew that since Ren Yuan had sold this pass, he must already have his own speculation, so he didn't bother to think about it, and kicked the ball back directly.

"Why are you so boring?" Ren Yuan was immediately dissatisfied, "You comrade, you have a problem with your thinking, this, this, lack of subjective initiative." ”

"Good, fine, I guess." Yu Qian thought for a moment and said, "It's impossible for the Advent faction to build a bus line in the underground water system, I guess before the water system is blocked, the falling corpses can flow down the water system to some surface river, they just need to wait there." ”

"You saw it on the sonar just now, right? Although that water system is not complicated, it is not to the extent that it can float corpses smoothly, right? ”

"That's... The Adventists also have a similar existence to the Fish-Men? As soon as the body fell, they carried the body away from the water? Yu Qian added, "Or is it like the crack, there are many tentacles, pushing and shoving to transport the corpse out?" ”

"Okay, you're already very close to the way you think in this business." Ren Yuan smiled and nodded, "Both of the methods you said are possible, but so far, I haven't found a lot of traces of tentacles growing in it." Combined with the fact that the oxygen in the veins was drained overnight, I guessed another possibility, and that was..."

At this moment, Jiang Ziwen's voice suddenly sounded in the communication channel

"Uncle Yu, Ren Yuan, I think it's better for you to come back early, someone from the ministry is here."
