If Zhao Nuo remembers correctly, the sewage treatment plant in the western suburbs of the city was still in operation until five years ago.

But during the drought four years ago, the river, which was already not very wide, dried up, and the nearby chemical plant continued to discharge wastewater into the riverbed, making it smelly.

As a result, the sewage treatment plant naturally stopped operating, but because the equipment inside was imported from abroad, no one would disassemble it for a while, so it was retained.

The new sewage treatment plant should be in the northern suburbs of the city.

After the location of the main outfall was replaced, the large drainage pipes near the western suburbs were also abandoned and replaced with new pipes to the north.

Then, if Zhou Yan's previous reasoning is correct, it is likely that the murderer acted through the abandoned drainage pipe here in Guò, but ......

Zhao Nuo still doesn't quite understand:

If this is the case, how did the murderer escape the police? And how can Zhou Yan be sure that he will definitely come here tonight?

Since she was sure that the murderer would be here, there weren't many possibilities left, could it be ......

Zhao Nuo, who was lurking in the shadows, was speculating, when he heard the hoarse young man's voice sound again:

"Little girl, you can't talk nonsense, you say that, uncle, I'm very sad."

Then, Zhou Yan's words confirmed his judgment:

"Come to think of it, the people who work here are the most suspicious, and when I came in to investigate last night, you also found me, right? That's why I'm so anxious to get rid of me. ”

"If you want to play a deduction game, go find someone else to play it, and you don't have any proof, little girl. Do you think that if you go to the police station empty-handed, those police officers will listen to you? ”

The hoarse voice was still very patient, and there was no anger at all. But Zhao Nuo felt a faint sense of danger from that voice:

-- This guy was joking, and he didn't mean to worry about the matter being revealed. If he were innocent, he would not be able to make small talk with someone who framed him on a dark night. So......

This person is indeed a murderer, yes, and he must have decided to get rid of Zhou Yan immediately!

Realizing this, Zhao Nuo immediately cast his gaze forward, trying to find the location of the man who spoke.

But even under the green vision of the night vision device, the guy was completely invisible, presumably hidden.

If you are a veteran employee of the sewage treatment plant, you must know the terrain here well, and it is not surprising that you can hide it.

"I've found evidence before, but I don't know where it fell." Zhou Yan said coldly: "That highlighter, you used it to mark the target, right?" ”

"Ah, that's what I played with." The man with a hoarse voice was still talking shamelessly, and at this time, Zhao Nuo also knew the direction from which the voice came from, and roughly determined the location of the other party.

- The night vision device could see through the darkness of the night, and could see several tall walls in front of the clearing, and the man should be hiding behind one of the walls.

The best option for now, though, is to keep waiting.

In the open space in front of the sewage treatment plant, there are no "bunkers" for self-concealment. If you rush out rashly, you are likely to be discovered by the two who are facing each other.

Even though I am very worried about Zhou Yan's safety, now is not the time......

Staring intently at the gap between several walls on the other side of the square, Zhao Nuo began to quickly calculate the distance:

Now he is less than thirty meters away from Zhou Yan, and if he rushes over, he will be able to arrive in about five seconds, but he will definitely be discovered.

He doesn't have any long-range weapons at hand, so he can only use the Knuckle Tiger in hand-to-hand combat. But if the enemy pinned down Zhou Yan first, it would definitely hinder his attack.

While thinking quickly about his next move, Zhao Nuo did not miss the chat between Zhou Yan and the killer:

"Don't talk about it, I also found the diary and the bloody clothes that I didn't have time to clean in your room, you should know exactly what is written in the diary, right?"

"What bloody clothes? Is it still there? As for the diary, it's a novel I wrote, do you think it's good? The hoarse male voice asked.

"It makes me want to vomit, completely unqualified." Zhou Yan, who is a scriptwriter, said mean words, while holding a dagger, and began to walk towards the wall in front of him.

- Stupid, don't go to death!

Zhao Nuo scolded countless times in his heart, but of course Zhou Yan couldn't hear it at all, and he didn't stop.

Although the distance was getting farther and farther away, Zhao Nuo could still feel that Zhou Yan's gestures exuded a terrifying aura of hatred.

Driven by extreme anger, the girl's thin body seemed to tremble slightly. At this time, the slow and logical male voice sounded again, and calmly admitted the fact that he had entered Zhou Yan's hut:

"Why did you kill me? I read the novel you left in your house, and we should be able to work together. ”

Hearing this, Zhou Yan finally shouted out uncontrollably:

"No kidding, what I hate the most is a damn murderer!"

It was only at this time that Zhao Nuo finally realized why Zhou Yan did not call the police, but came here to negotiate with the murderer head-on.

- This girl really did not let go of what had happened, she did not come to send her to death, but wanted to punish the murderer with her own hands!

Seeing that she had already rushed to the wall in front of her, Zhao Nuo also slipped out of the bushes and advanced towards the other side of the clearing against the wall.

In the current situation, there is no time left for herself to continue to think about action strategies, she must be as close to Zhou Yan as possible, otherwise she will really be killed if she is impulsive!

Rushing to the front of the clearing under the cover of night, Zhao Nuo knew that now the murderer only had to look to the left, and he would be discovered immediately.

However, there is no other way!

Even while running quickly, he didn't take his eyes off Zhou Yan. At this moment, from the gap between the two walls, an extremely dangerous tall figure also stood out......

"Smack!"

The tall man raised the gun-shaped object in his hand, and the girl who was still rushing towards him suddenly convulsed all over her body, and then collapsed weakly to the ground, obviously fainting.

- What is that? Tranquilizer guns? Wrong...... Is it a taser?

Zhao Nuo, who had seen that kind of thing in the game, quickly recognized the murderer's weapon:

-- Tasers, a non-lethal weapon favored by many police officers in Europe and the United States. It doesn't fire bullets, but two tiny electrodes connected to copper wires. Once it hits the target, it can immediately release a weak high-voltage current to stun the enemy in an instant.

With the "stopping power" of this weapon, let alone Zhou Yan, even if a big man with a strong ox rushes over, he will be directly knocked unconscious!

"It doesn't look like it's going to be the head."

Realizing that the other party was holding a weapon that could stun him instantly, Zhao Nuo immediately rushed to the corner of the clearing and crawled on the ground while continuing to observe the murderer's movements.

There is no doubt that this murderer is very confident, and from the conversation just now, it seems that he is not in a hurry to kill Zhou Yan, but as if he has met a "confidant", he appreciates Zhou Yan, who also has a cruel character.

What I have to do now is to wait for a suitable moment......

Under Zhao Nuo's gaze, the tall man inserted the taser back into the belt around his waist.

Then, the guy bent down, picked Zhou Yan up by the waist, and carried the unconscious girl to the other side of the clearing, in the direction of the sewage treatment plant building.

Seeing that the murderer had his back to him, Zhao Nuo stood up silently, lowered his voice as much as possible, and tiptoed to follow.

It seems that because of carrying people, the murderer who used mobile phone lighting did not walk very fast.

Zhao Nuo, who followed behind the murderer like a ghost, slowly narrowed the distance between him and the other party. When he found that he was less than ten meters away from the murderer, he quietly clenched his fists, and then his eyes widened.

Now is the time!

The "agent", who lowered his body and wore a black combat suit and a night vision device, sprang out like a cheetah and rushed towards the unsuspecting murderer in front of him.
