At this time, He Yi seemed to be working overtime, and the whole room was empty.

It's a good time for her to do something.

Yu Sheng came out of the space and swept his gaze over Cheng Shi in the room.

The place where He Yi lives is a three-bedroom and two-hall area of about 120 square meters.

The interior of the house is simple and cold, most of the furniture is white and gray, and even the curtains are black and gray.

Occasionally, a few touches of blue are used as embellishments to add a touch of brightness to the whole room.

It gives a cold, lonely feeling.

It is very different from the sunny and upright He Yi she usually knows and has two cute dimples when she laughs.

Yu Sheng didn't make any cover-up, and went directly to He Yi's study.

On the desk is an expensive laptop and a picture frame table.

In the photo in the frame, He Yi is wearing a police uniform, with a bright smile on his face, and the two small dimples on his cheeks are intoxicating.

He saluted at the five-star red flag, his eyes unwavering.

is no different from the He Yi she knows on weekdays.

Yu Sheng just glanced at it a few times, and then silently turned on He Yi's computer.

After a purposeful operation, he knocked over the photo frame as if unintentionally, and the photo frame suddenly collapsed on the desk.

Immediately, worried that the guy would not be able to find her head, he quickly pulled a hair and threw it in an inconspicuous place under the chair.

After doing all this, Yu Sheng flashed back to the space and left through the window.

The space moved quickly, and soon went to the place where He Yi worked.

After looking for a night, I didn't find the blade that stabbed Autumn Night last time.

In desperation, Yu Sheng could only hide in the space and guard there.

I thought I would wait for everyone to get off work and continue to look for it.

After a while, Yu Sheng saw He Yi and Xiao Zhang from the space.

So, she simply got into He Yi's clothes pocket so that she could eavesdrop on the case.

"He Yi, when are we going to Haoyang Group?" Xiao Zhang asked as he ate the buns.

“…… You can find someone else to accompany you, I've got something to do. He Yi was silent for a long time before he spoke.

After returning last night, he found something unusual in his home.

With a cautious mind, he immediately took out his evidence bag and began to collect evidence.

The doors and windows are intact and there are no signs of breakage.

But he was 100% sure that someone had visited.

Sure enough, when he searched carefully, he found that nothing was missing from the house.

However, the computer was touched and a fingerprint and a hair were found.

So, he wanted to send his head to the technical department to check it out and see who was looking through his computer while he wasn't at home.

What was the purpose of that man?

Could it be related to the case he is investigating?

Thinking like this, He Yi was a little distracted for a while.

Xiao Zhang talked to himself for a long time, but saw He Yi in a daze.

At that moment, his face darkened, and he gritted his teeth and said, "We're still not good brothers?" What happened to you? Do you want me to help you solve it, brother? ”

"......" He Yi came back to his senses, looked at Xiao Zhang and stopped talking.

"Oh, you mean! Can't you still trust me, brother? Xiao Zhang was originally a character who jumped out, and when he saw He Yi like this, he couldn't help but be a little anxious.

"Well, I'll tell you anyway! It's like this......"

He Yi had no choice but to take Xiao Zhang to the window, and whispered to him what he found last night.

"So, you suspect that the murderer is targeting you?" Xiao Zhang put away his casual posture and asked with a solemn expression.

"Not necessarily, I'm just skeptical right now. Maybe...... It's just a thief? He Yi squinted his eyes and looked into the distance.

No one knew what was going on in his mind.

"Cut, you haven't lost anything at home, what kind of stupid thief would do such a secret room 'theft' to decrypt for you?" Xiao Zhang rolled his eyes and said speechlessly.

"......" He Yi pursed his lips and said nothing when he heard this.

Even what Xiao Zhang can think of, he can naturally think of.

It's just that everything will not be known until the test results come out.

"Okay, leave the affairs of Haohui Group to me, you hurry up and go to the technical department! If it's really the murderer who comes to provoke him, we can't let him look down on him. As he spoke, Xiao Zhang patted He Yi on the shoulder.

"Okay." He Yi nodded, took his things and left.

Yu Sheng listened to the words of the two and couldn't help but sigh in his heart.

Sure enough, the male protagonist is different, and his sensitivity is so high.

After He Yi went to the technical department, he put down his things and went to the evidence room.

I took out a series of certificates, signed them, and walked in.

Yu Sheng wondered, what is this guy doing here?

With curiosity, she took control of the space and left He Yi's pocket.

I saw that He Yi walked to a safe with a clear purpose, took out the key to open it, and then took out a file bag inside.

Yu Sheng got a little closer, and at a glance, he saw the words 'vacuum-packed serial murder case' written on the file bag.

"It's hiding here, no wonder I can't find it." Yu Sheng's eyes lit up and he muttered to himself.

He Yi took the document bag, walked to the door, and poured out the contents inside.

Seeing this, the police officer guarding the door did not ask much.

As a criminal police officer, sometimes I will come to confirm the evidence from time to time.

He Yi picked up the blade in the transparent plastic bag and looked at the blade with a deep gaze.

He has already investigated, this kind of blade is a medical exclusive blade, the blade is also clearly separated from the blade, and the blade can be removed and replaced.

However, when he found Yu Sheng.

She only held the blade in her hand, but she didn't see the blade.

This kind of blade will never be bought by ordinary people, after all, it is not widely used, and it is too sharp to easily injure people.

At first, he did not suspect that the murderer could be a doctor or someone who was involved in hospitals or blade manufacturers.

However, after this period of investigation, this possibility has been basically ruled out.

So, will it be ......

Thinking of this, He Yi put down the blade and prepared to take a closer look at the test results.

Yu Sheng's heart tightened, and he was thinking about whether to find a way to lure He Yi away, but he heard He Yi's phone ringing.

He Yi answered the phone, and the person over there didn't know what to say, and then hung up in a hurry.

"Brother, I didn't take this information with me, I have something to leave now, please put the information back in the safe." He Yi said quickly.

"Okay, you can sign it here." The officer nodded.

"Okay." He Yi nodded, and after signing the paper, he rushed away.

Seeing this, Yu Sheng breathed a sigh of relief.

After the police put the file bag back in the safe, Yu Sheng quietly took the key.

Then he lay down peacefully on the grass of the space......
