Chapter 260 The Real Source of Stimulation (IV)

Time passed bit by bit, and Han Xu was like a machine, browsing the photos on his phone at a rapid speed.

The other three people couldn't keep up, and they all stared at Han Xu with horror!

"Fuck, are you still human?" Qin Fen took a breath, "Should we send him to the research institute!"

"Heh, you think Han Xu is Pili Beibei?" Guo Jia glanced at Captain Qin, who had a clear mind, and said without hesitation.

Qi Shen was the first time to see someone with such abnormal eyesight, and his mind was full of thoughts whether Han Xu was deliberately making a mystery, how could a human being do such a thing.

In the eyes of the three people who were either surprised or puzzled, Han Xu finally stopped sliding his fingers on the screen.

"Yes, this is it, I found it!"

As Han Xu's voice fell, the three people were completely numb!

"Fuck, you really found it!" Qin Fen couldn't wait to look over.

I saw a photo not too old frozen on the phone, with a young couple standing on it. The man was naturally Qi Shen standing in front of me, and the woman was his ex-wife Nie Xiaoyu.

Guo Jia and Qi Shen came up together!

Guo Jia's expression was similar to Qin Fen's, both of them were puzzled, because they did not find any elements related to butterflies.

Qi Shen frowned, "This photo was taken when we went to Yuntai Mountain together. Behind us is the famous Fountain of Youth! But there seems to be no butterfly on it!"

Han Xu glanced at the three people, smiled and pointed at what Nie Xiaoyu was holding in her right hand.

The three people looked closely and immediately understood.

It was a key chain, only half of which was exposed, and the other half was tightly held in Nie Xiaoyu's hand.

From the half of the key chain that was exposed, it could be vaguely judged that it was a metal ornament with a half butterfly pattern!

"Huh! Why have I never seen this key chain before?" Qi Shen was surprised, and he was sure that he had never seen this thing before.

Qin Fen looked at the photo, then raised his head to look at Han Xu, "How did you see such a small thing? And..."

"It flipped so fast!" Guo Jia added the rest of the words in shock.

Han Xu smiled awkwardly and explained reluctantly, "My eyes have been good since I was a child, and I can see things faster than others!"

"Is that fast?" Qin Fen opened his mouth and couldn't speak clearly, "You...you are frighteningly fast, okay?"

Guo Jia was about to say something else, but Han Xu stopped him in a hurry, "It's just a little faster, let's investigate the case first, the case is more important!"

Then he asked Xiang Qi Shen, "When was this photo taken, do you remember?"

"Of course I remember, I only went to Yuntai Mountain once, it was a month before Xiaoyu's accident," Qi Shen answered without thinking.

"The time is right," Han Xu looked at Guo Jia again.

How could Guo Jia not understand what he meant? He quickly replied, "This keychain was not found in the items carried by Nie Xiaoyu, nor in her belongings!"

"There is no record in the data either," Han Xu was almost certain that the keychain with butterfly elements was taken away by the murderer!

And the real stimulus for this serial killer is butterflies!

"Oh, I can't tell, this is also a butterfly killer!" Qin Fen summed up a very appropriate nickname.

"Butterfly killer?" Guo Jia shook his head speechlessly, and his eyes looking at Han Xu had all turned into admiration!

The reason is that Yao Yang has mobilized countless elite detectives in the police world and has found nothing in five years, but how many days has Han Xu been involved in this case?

You can count them with one hand!

This magical ability to solve cases is really beyond Guo Jia's cognition!

No wonder he is already an acting team leader at a young age, and no wonder the captain of the criminal investigation team is willing to be a little assistant!

Qin Fen had long been numb to Han Xu's ability to solve cases, and no strange things could shake him!

At this time, Han Xu had copied the photo and said to Qi Shen, "Thank you, Mr. Qi, if the case is solved, we will notify you as soon as possible."

Qi Shen didn't expect that he would really help the case, and his eyes were red, "I should thank you on behalf of Xiaoyu!"

The three of them exchanged a few more polite words before saying goodbye to Qi Shen and returning to the car.

"Now that the source of the stimulus has been found, do we still need to look for Wang Yuan?" Guo Jia asked impatiently as soon as he got in the car and his butt was not yet firmly seated.

It's not his fault. It's really been too long. It's also the first time that Guo Jia has been so close to the murderer. His long-cherished wish is about to be fulfilled, so it's inevitable that he is a little excited.

Before Han Xu could speak, Qin Fen replied, "We still have to go find Wang Yuan. Although the source of the stimulus has been found, the evidence has not yet been closed. We still need to go there."

Han Xu nodded and said, "Captain Qin is right. We also need to verify Wang Yuan and complete the chain of evidence."

Guo Jia actually knew this truth, but he was a little too excited. He slapped his forehead and said, "Okay, let's go back to the hotel!"

The three of them rushed to the hotel without stopping. It happened that Wang Yuan had already got off work.

After asking Wang Yuan's address, the three of them rushed over again.

Wang Yuan never thought that the police officers he had just met in the morning would come again before dusk.

"Why are you here again?"

Guo Jia seemed to have heard this line somewhere before, and smiled, "Sorry to bother you again. We have some very important things to check with you!"

"Important things?" Wang Yuan was a little confused, "Why didn't you say it this morning?"

Guo Jia was rebuked for no reason, and he didn't know what to say for a long time.

Han Xu quickly continued, "We made a major discovery this afternoon, so we came to verify with you."

When Wang Yuan heard this, he lost his temper instantly and said reluctantly, "Okay, then, come in."

After the three of them entered Wang Yuan's rented room one after another, Han Xu chose to get straight to the point, "Did Dong Jiayan like butterflies when she was alive?"

Wang Yuan was about to pour water for the few people, and paused when he heard it, "I haven't heard her say that she likes that kind of thing! Butterflies?! It seems that she really doesn't!"

After getting this obviously useless answer, Han Xu still didn't give up, "Then have you seen anything related to butterflies on her? For example, patterns on clothes, decorations on key chains, or bracelets or something."

Wang Yuan was even more confused after hearing this, "Officer, why are you asking this?"

"It's related to the case, think about it carefully," Guo Jia replied anxiously.

When Wang Yuan heard that it was related to the case, he immediately stopped talking, as if he had put all his thoughts into memories.

However, after a while, Wang Yuan still frowned and shook his head, "Sorry, I can't seem to help you."

Han Xu looked at Wang Yuan, who looked a little lonely, "It's okay, if you think of anything, let us know!"
