"Then let's follow!" Lin Qing said in a gentle tone.

Mu Yuan could only nod in agreement.

At this moment, Ermao suddenly turned his direction and slipped into a stairwell next to him.

"Huh, let's go! Mu Yuan said happily.

Lin Qing looked at Erha, who was walking in front, and then at Mu Yuan, and a strange idea popped up in her mind.

"Hey, if you make two, you will make two!" Lin Qing thought so, so she had no choice but to follow.

Erha ran to the stairs in a few steps, and his little short legs were raised......

It's embarrassing, I can't climb up.

But this little guy has a lot of backbone, and his whole body is fluttering in place, as if he wants to go up the stairs by his own efforts.

struggled for more than ten seconds...... Still didn't work out.

Mu Yuan squatted down helplessly and held Ermao in his arms.

"Look at how useful you are!" Mu Yuan complained slightly, and then listened to Ermao's whining cry and walked upstairs.

"Woo ......"

Mu Yuan walked up to the next floor......

"Woo ......"

Keep going up.

Lin Qing was full of grievances, who did she offend......?

Although she had also heard of some of Mu Yuan's deeds, she really couldn't connect this guy with the expert in handling the case in front of her.

Suddenly, Ermao screamed a few times in a row.

Mu Yuan immediately stopped, squatted down and put Ermao down.

This is the fifth floor, and the number "five" on the wall is very mottled, and it looks very old.

There is a security door on each side of the staircase, which is different in style, but there is one thing that is very similar, that is, - old.

The rusty security door and the dimly lit corridor are quite a good match.

Lin Qing found that after Ermao landed, he suddenly looked very manic.

After swaying around in place, it quickly ran to an anti-theft door, and then raised its little head and kept "whining" towards Mu Yuan.

"It'...... What do you mean?" asked Lin Qing with a pair of big innocent eyes.

Mu Yuan took a closer look at the door, took a deep breath, and his expression was very serious.

"That man, probably from here. ”

"Are you sure?"

"It's certain. Mu Yuan raised his chin towards Ermao.

"How can you be sure it's confirmed?" Lin Qing asked.

Mu Yuan said: "It's a dog I bringed, I naturally understand." ”

Lin Qing glanced at the closed door again, hesitated for a moment, and then asked, "Then what now?"

Mu Yuan looked at the keyhole, suppressed the restlessness in his heart, and said, "Give your team a call and ask them to find out who lives here." ”

Lin Qing didn't say a word, directly took out her mobile phone and dialed the phone number of Captain Yue.

"Team Yue, we are now in Unit 3, No. 7 Siming Lane. ...... How did we find here? Well, it was the husky from Mu Yuan who brought us here...... I don't know, you can arrange for someone to check who lives in room 2 on the fifth floor. ”

After speaking, Lin Qing waited silently like that.

The whole staircase was eerily quiet.

After more than a minute, Lin Qing answered a few times and hung up the phone.

"People found out that the person who lives here is a person named Wang Siyun, who is a tenant. ”

Mu Yuan frowned slightly, and asked, "What should I do if Team Yue didn't say anything?"

"They are still checking information about Wang Siyun. Lin Qing's mood is a little complicated.

In her opinion, this ...... It's child's play.

However, as soon as she finished saying this, her phone rang again.

Lin Qing looked down, frowned slightly, and said, "It was the Yue Brigade who called." ”

With that, she answered the phone and pressed the speakerphone.

"Lin Qing, you and Xiao Mu don't move there, we'll come over immediately. ”

Brigade Yue's voice was full of urgency, and then ...... Hung up.

Lin Qing's expression is extremely exciting, what is the situation?

According to her understanding, when the general Yue brigade has such an expression, most of them have made a major discovery.

Could it be that there is something really wrong with this room?

Lin Qing couldn't help but turn her head and glance at Mu Yuan, her beautiful big eyes were full of suspicion.

Mu Yuan looked very calm, walked leisurely to the anti-theft door, and looked at the doorknob and door frame with a pair of eyes.

"Is there anything wrong with this?" Lin Qing has been in the police force for a year, but she feels that even the day she first went to work, she is not as dazed as she is today.

Mu Yuan said leisurely: "The door is definitely fine, I just want to see if there are any fingerprints on it." ”

Lin Qing looked stunned and said, "The fingerprints on the door can be seen with the naked eye?"

"If you look closely, you can see it. ”

Lin Qing almost doubted life, whether she could see it or not, was there an inevitable connection with whether she saw it carefully?

Just as Lin Qing was about to refute, Mu Yuan suddenly said, "Lin Qing, I guess I have to contact someone to remove this doorknob." ”

"Why?"

"There's really fingerprints on this doorknob. ”

Lin Qing couldn't help the curiosity in her heart and leaned her head over.

Mu Yuan paused, and then moved to the side......

Lin Qing stared at it for a few seconds, the doorknob was still the same doorknob, and she didn't see anything else.

However, Lin Qing's sense of evidence is still very strong, and she didn't touch the doorknob with her hand.

In the end, after Lin Qing was sure that she hadn't seen anything, she looked back at Mu Yuan and said with a trick on her head, "You're lying, aren't you?"

Mu Yuan was immediately depressed: I am such a loyal and honest person, why can you bear to label me as a "liar"?

Sure enough, women like to mess around and start wearing hats when they find themselves at a disadvantage......

"I never lie. Although Mu Yuan didn't want to speak, he still explained.

He said a sentence when he listened to Wan's teaching to mediate family disputes at the Qinglong Street Police Station before, and he felt that it was very reasonable: husband and wife should communicate more, and if they don't communicate, they are prone to conflicts.

In fact, it is not only between husband and wife? People also need to communicate with each other.

Lin Qing looked at Mu Yuan's serious appearance, and then looked at Ermao, who was seriously helping him "shine his shoes": Why are these two guys' persistence so similar?

......

Captain Yue and his entourage quickly rushed to Siming Lane, and when they came to Unit 3 of Building 7, they finally cracked the embarrassing atmosphere here.

It was not only Captain Yue and several other policemen from the Criminal University who came, but also Director Wu and Director Feng, as well as Deputy Director Zheng in charge of criminal investigation in Qingyu County.

When Lin Qing saw this formation, she immediately guessed that her inference just now might have been confirmed.

Here - there must be a problem.

Sure enough, as soon as Feng Ju, who was walking in the front, came up, he slapped Mu Yuan on the shoulder and said with a smile: "You kid is capable! ”

Mu Yuan's eyelids jumped, smiled, and said, "Ermao smelled it." ”

Feng Ju glanced down at the young Erha, smiled heartily, and said, "Ermao can't stand my slap, so you can help it bear it." ”

Mu Yuan didn't want to speak......

"In this room?" Feng Ju asked, pointing to the door facing Mu Yuan.

Mu Yuan nodded and advised, "There are fingerprints on the doorknob, it's best not to move." ”

"Oh?" Feng Ju suddenly became interested.

About Mu Yuan's ...... of fingerprints Feng Ju only knows a thing or two about the ability to discriminate, so compared to Lin Qing's complete disbelief, he is cautious.

"Director Wu, are there any technical police officers coming along?" Director Feng immediately asked.

Director Wu nodded and said, "Yes!"

Captain Yue stared at the doorknob with a bitter face, and said, "Bureau Feng, if you want to extract the fingerprints on this doorknob, I'm afraid the technical strength of our county bureau is a little insufficient." In case the evidence is destroyed......"

I didn't say the rest of the words, but everyone understood.

Director Feng's gaze fell on the doorknob again, his brows furrowed slightly, and said, "Now I can remove this doorknob first, but I can't destroy the fingerprints on it." Do you want someone to cut it?"

Lin Qing, who was standing on the edge because of the crowding, felt a little stimulated.

The leader has something wrong with his brain, right? Just because of one sentence, he will engage in violent cutting? And looking at Feng Ju's attitude, it is estimated that the whole door will be cut down!

In fact, it is not only Lin Qing who has this idea, but also the people in the Qingyu County Bureau are skeptical.

But...... Others are cautious and suspicious, although it can't be said that there must be fingerprints on the doorknob, but it can't be ruled out that there are no fingerprints on it, right?

"Brother Zhou, what's going on?" Lin Qing gently touched the shoulder of a colleague next to her and asked in a low voice.

"You don't know?" Brother Zhou looked strange.

Lin Qing's face was blank and said, "What do I know?"

Brother Zhou paused and said, "Just now we checked Wang Siyun's situation, and we found one of his traffic accident information. Two years ago, he had been in a car accident and fractured his left lower leg! According to the autopsy, the victim had an old fracture in the lower leg of his left leg. ”

Lin Qing's eyes widened, as if she had heard something incredible.

Then, she suddenly looked at Ermao, who was already in Mu Yuan's arms, as if she was looking at a fairy......

"You ...... Was it really brought here by that puppy?" Brother Zhou's shock didn't have to be Lin Qingshao.

"Or what do you think?"

"It's incredible. ”

“......”

"If nothing else, the victim is probably Wang Siyun. Now the bureau has arranged for someone to investigate Wang Siyun's relevant information. According to what we have found now, Wang Siyun is a chef, and his recent record of employment is to work as a chef in the Red Leaf Restaurant, and our people are now rushing over to investigate. ”

When Lin Qing and the two discussed in private, Feng Ju's side was also not idle.

"Feng Ju, the cutting is not very safe!"

"What else can you do if you don't cut it? Now that the landlord is not in Xihua City, you can't wait for him to come back and investigate, right?"

Mu Yuan suddenly spoke: "Feng Ju, I can open the door." As soon as the door is opened, it is easy to get the doorknob. Moreover, I know the location of the fingerprint, and it will not destroy the fingerprint. ”

"Can you open the door?" Feng Ju looked stunned.
