The task assigned to them by the Martial Arts Academy was to encounter the demon beast as soon as possible and then kill it.

But for Gu Yuan, the task has changed.

He needed to figure out what that little yellow dog had gone through, why he killed Wang Yanfeng and the others, even to the point of chasing after him.

What kind of hatred can there be between them?

When he was on the mountain before, the little yellow dog faced Gu Yuan and didn't make a move, which showed that his brain was awake.

In the yamen.

Gu Jianshan was already waiting for them.

"Second uncle, I have to trouble you."

Gu Jianshan shook his head.

"Don't say that, if it's really what you say, it's a mistake in our work." Gu Jianshan took Gu Yuan and Wei Xuanyi into a small conference room and sat down, and asked, "Xiao Yuanzi, do you mean that Xie Erlan's death was not a pure sudden illness?" ”

Gu Yuan's expression was solemn and he nodded.

Wei Xuanyi was curious: "Who is Xie Erlan?" ”

Gu Yuan glanced at her: "It's the previous owner of the little yellow dog." ”

"The old woman?"

"Hmm."

Wei Xuanyi's face changed slightly.

"It's not that the old woman had a heart ......attack," Wei Xuanyi's voice became smaller and smaller.

The information between her and Gu Yuan is actually synchronized, and what Gu Yuan can think of, she can also think of.

"You mean, that old woman's death actually has something to do with Wang Yanfeng and them?"

"It's just speculation, I can't say for sure for now, but it's the most likely." Gu Yuan said in a deep voice.

Wei Xuanyi said angrily: "It must be so!" Otherwise, how could that puppy not be relentless? It's revenge! ”

Gu Jianshan looked at Wei Xuanyi and cast a puzzled look at Gu Yuan.

Gu Yuan said helplessly: "Second uncle, this is my classmate, my temper is so short-tempered, don't bother with her." ”

Gu Jianshan smiled.

There was a knock on the door, and Chen Yuan walked in, still holding some materials in his hand.

"Boss!"

"Well, it's good that you're here, let's talk." Gu Jianshan got up and said to Gu Yuan, "Xie Erlan's case is handled with the kid, you can ask." ”

"Okay."

Chen Yuan sat in the position where Gu Jianshan was sitting before, and was stared at by Gu Yuan and Wei Xuanyi with scrutinizing eyes, and he was immediately a little panicked.

"Don't scare me, little ball! What's going on? What happened to Sherlan's case? ”

Wei Xuanyi slapped the table and scolded angrily: "Boy, do you know what kind of place this is? Are you hiding something? Resist leniency and confess strictly! ”

"Yes, yes......" Chen Yuan nodded like a chicken pecking rice, and then, "Huh?" ”

Is there something wrong?

"That's the other way around." Gu Yuan reminded in a low voice.

"Well, yes......" Wei Xuanyi scratched his head.

Chen Yuan couldn't laugh or cry.

"If you want to ask anything, you can ask, it ......looks like I'm going in," Chen Yuan said, opened the information, and explained, "Actually, the boss briefly told me that the cause of Xie Erlan's death was indeed a heart attack. ”

Gu Yuan took the information and flipped through it carefully.

Chen Yuan sighed and said, "This is the firm determination of the professional organization, and there will be no mistakes." ”

"However, if you have a heart attack, you can't rule out external factors, right?" Wei Xuanyi said, "For example, scared? It's like roller coasters, haunted houses, etc., you can't participate if you have a heart attack. ”

"That's right."

"Can we go and see it?" Gu Yuan asked.

"Now?" Chen Yuan was stunned, "How long has it been, even if you go, you won't find anything, right?" But since you're going, it's better to go. ”

"I'm sorry for you, Brother Yuan."

Chen Yuan waved his hand and said with a wry smile: "Don't talk about this, if there is really a hidden secret in it, it is my work mistake." ”

In the car, Chen Yuan also briefly introduced the situation.

The location where Xie Erlan's body was found was not very far away, so after receiving the report, Chen Yuan quickly arrived, and the forensic doctor at the scene judged that it was a heart attack, and it was further determined.

And the person who reported the crime was selling breakfast, and he arrived at dawn, and then made a call.

Coming to the place, Gu Yuan looked around.

"The traffic here is still relatively small, especially during this time, and the road has been being built later." Chen Yuan said.

"Isn't there any surveillance?" Wei Xuanyi asked.

"If there was surveillance, it wouldn't be so complicated, and this section of the road happens to be unmonitored." Chen Yuan said, "The nearest probe can't be taken here. ”

Wei Xuanyi was a little disappointed.

Chen Yuan ran to the small supermarket next to him and bought two bottles of water and handed them to Gu Yuan and Wei Xuanyi.

"How's it going, did you find anything?"

Gu Yuan shook his head.

He looked up and looked at the small supermarket.

"Isn't there surveillance at the door of this small supermarket?"

"We've seen it." Chen Yuan said, "We went to see it that day, but the monitoring of this small supermarket has long been broken, and it is completely a deterrent." ”

Gu Yuan sighed.

"That's it, Brother Yuan, please do me a favor." Gu Yuan said, "Find out the surveillance on this road first, and it doesn't matter if you can't shoot here." ”

"Are you looking for something?"

"Let's see." Gu Yuan said.

Chen Yuan pondered for a moment and nodded.

"It's not a long time, I'll contact the transportation department first."

"Okay."

After drinking half a bottle of water, Gu Yuan stood in the shade of the tree, and Wei Xuanyi next to him suddenly spoke.

"From here, to the Martial Arts Academy, it's actually quite far."

"Hmm."

"She must have been gone for a long time, right?"

Gu Yuan nodded lightly, and this time, he didn't speak.

Soon, Chen Yuan returned.

"Xiaoyuanzi, there's no problem, I've already communicated! Let's go now! ”

"Okay."

This time, it was Chen Yuan who drove and pulled Gu Yuan to the traffic team.

Chen Yuan was quite familiar with the people here, and after a few words of greeting, he took Gu Yuan and Wei Xuanyi into an office.

"The surveillance video you want is here."

"Lao Lu, thank you!"

"For the sake of handling the case! Say thank you for business. The man named Lao Lu scolded with a smile, "If it's not for business, even if you want to check if your daughter-in-law ran away with someone, I won't help." ”

I heard Chen Yuan say that Lao Lu and him were classmates before, so the two talked more casually.

"You two watch it first, it's just playing, pausing, slowing down or something." Lao Lu said.

"Okay, you go get busy first."

Chen Yuan sat on a chair and played a video, with a total of six frames.

"This is monitoring on the Nebula Road." Chen Yuan said, "If you need another way, you can also call it out." ”

"No, let's look at this first."

Chen Yuan glanced back at him and found that Gu Yuan's eyes kept moving back and forth.

It's like I'm looking for something.

Suddenly.

Wei Xuanyi shouted.

"Here!"

Although it was night, the footage was not clear, but the old man and the dog were too conspicuous, especially on this empty road.

Gu Yuan watched the old man and the dog appear in the picture, and then walked out of the monitoring range, and then, in the second monitoring screen, the lonely shadow was stretched and shrunk by the street lamp.

It's like dough rubbed around by fate.

It was at this time.

Gu Yuan's originally soft gaze suddenly sharpened.

He stared at the screen, his voice muffled.

"Slow down."

"Oh oh, good! Huh......" Chen Yuan, who was holding the mouse, also noticed something at this moment, revealing a look of astonishment.

"It's really ...... them," Wei Xuanyi pursed his lips.
