Risking their lives to solve the case, criminals all over the network are going crazy

Well?

Liu Yu opened the micro-expression psychology skill, and doubts flashed in his heart.

He replied so quickly that he didn't even have the slightest hesitation.

It seems... He was waiting for this question.

His pupils contracted sharply, obviously excited, excited, waiting for what he wanted.

But his expression remained very calm, calm, and unhurried.

Even the action of pouring tea is a steady batch.

Liu Yu twitched the corner of his mouth: "Talk about it."

"Mr. Zheng, my mental state has been bad recently, and I heard him say that it was a sleep problem, but he didn't say anything about the specific problem."

Speaking of this, suddenly Gao Lei's voice fell, moved his butt, and whispered.

"The boss has a psychological problem."

Liu Yu and several people exchanged a look.

What does it mean that there is a psychological problem.

One is: psychopathy.

The second is: common mental illness.

"What problem?" Li Sansi narrowed his eyes slightly and asked suspiciously.

"More than a month ago, he asked me something, do you know a more famous psychologist, he feels more anxious recently."

"Although President Zheng just said such a sentence, we as secretaries naturally have to understand what he means, and he is a little difficult to say."

"It just so happens that I know a good psychiatrist in our city called Wang Ming!"

"Help him make an appointment to go to Mr. Zheng's house once."

"There is nothing unusual about the rest."

"Oh, there is another one, Mr. Zheng has been taking Chinese medicine to condition his body recently, as if he is preparing for pregnancy."

"I wonder if this counts?"

When Liu Yu heard this, he was stunned.

Trying to get pregnant?

Old to get a son?

By the way, didn't he and Su Xuehan have children?

He and Su Xuehan... There are really no children, the only child is a son left behind by his ex-wife, twenty-four years old this year, studying abroad.

Most likely, this was Su Xuehan's request.

If one day the old Zheng Yi is dead, then how can a young widow inherit such a big family business.

Gao Lei bent down slightly again, stretched out his head, and whispered.

"I heard that our boss's son will return to the company at the end of the year, and I guess that his wife proposed to get pregnant, and I want to have a son to compete for a little family property..."

This... The secretary does not go to the paparazzi, it's a pity.

But also normal, one of the two categories of people closest to the boss.

Secretary and driver.

Often with the boss, if these people blow something, it is easy to discredit others.

Therefore, there is a rumor that the most unoffended are these two types of people.

Smear you all the time, without a trace, can you stand it.

Return to the Criminal Investigation Brigade.

Forensic Room!

A breath of cold air rushed in from the dissection room.

Yao Da!

Wearing protective clothing, transparent face shields, masks, being .... Dissect.

Of course, wearing it so tightly is to protect yourself and prevent things like corpse blood from splashing into your eyes.

Don't underestimate this, Liu Yu remembered that in his previous life, a forensic doctor in his unit was precisely because when dissecting a corpse, tissue fluid splashed on the forensic doctor's face.

There was just a wound on the face, stained with tissue fluid, so it was infected, fever and fever, leaving a lifelong scar.

Including, wearing masks at some crime scenes.

In addition to protecting yourself, you are also able to cover your facial expressions.

In case of being photographed by the surrounding onlookers, without wearing a mask, some expressions that should not be in the middle of interpretation can easily cause secondary public opinion.

·····

Not suicide. Drinking suicide is suicide by way a bullet enters the mouth.

Strictly speaking, Zheng Yinian was shot in the head.

A shot was shot in the temple, and the bullet went directly into the brain, causing death.

When the temple is subjected to a strong impact, a small hole in it will close quickly...

Gun, not a traditional pistol.

Liu Yu looked at an earthen gun placed on the evidence cabinet.

What is a gun?

What is the definition of a gun?

Energy! That's right, it's energy.

There is a unit called Joule.

By measuring the joules of the gun at the time of firing, it is defined whether the range of the gun is reached.

In the processing and decoration industry, there is a tool called air nail gun.

The power is very large, and it can easily penetrate ordinary wooden boards and drive nails in.

With a little processing and modification, it can easily be turned into something similar to a pistol.

This blood-stained earthen gun was transformed by a miniature air nail gun.

President Zheng also plays with guns?

A strange thought popped up in Liu Yu's mind.

However, Mr. Zheng's manufacture of cartons, packaging boxes, and bags will involve this thing.

The gun after the magic change has become a charging gun, usually powered by batteries.

Rotate at high speed, push the air, form a high pressure, and knock out the nails inside.

Although the power is not as good as that of ordinary pistols, it is easy enough to enter the human body.

Especially in such a fragile part of the head, it is too normal to be killed with one shot.

The king of smells!

As soon as the skills are turned on, eh? Liu Yu's brows furrowed instantly, this gun had a bitter almond smell on it, very light and light, if it wasn't for his own hanging, he wouldn't smell it at all.

Involuntarily thought of a highly toxic substance.

"Cyanide!"

"A small dose is enough to poison an elephant, and a drop is enough to kill dozens of people."

what？

This old boy was afraid that this air nail gun would not kill himself with a single bullet, and he also smeared cyanide on the bullet, which could quickly end his life.

Tough enough!

But Yao's autopsy showed no signs of poisoning.

So what's going on with this thing.

However, I immediately figured out that the deceased did not take highly toxic cyanide, but smeared it on bullets and shot into the brain, and for a while and a half it really could not flow all over the body.

Therefore, no highly toxic detection has been detected in other tissues.

In addition to the bitter almond smell, I also smelled the smell of three people.

Liu Yu was a little surprised, this skill is really ™ strong.

It's like a dog, and you can smell a lot of smells by sniffing.

The remaining three smells are the smell of secretary Gao Lei, wife Su Xuehan, and Zheng Yinian.

Liu Yu's eyes rolled.

Could it be that they also touched this gun?

Even, it was the secretary who shot?

Twenty minutes in the study, everything can be done. But what about the evidence? No.

There is also the possibility that the secretary stayed in it for so long that the smell left behind stained the gun.

As for Su Xuehan's smell, it is easier to explain, and the place where he often lives, leaving a strong smell, is normal.

Liu Yu carefully looked at the special shape of the bullet in the physical evidence box, the fluid shape, and the very small letter imprint, and the workmanship was exquisite.

It seems that where have he seen it, Liu Yu couldn't help but think, and then he took a photo and passed it on to a strange old friend, Tang Zhengli!

Perhaps, he will understand better.

Immediately afterwards, Liu Yu muffled towards the newcomer's forensic assistant: "Xiao Tao, check if this bullet is poisonous." "

Xiao Tao is a new medical student recruited this year, and he was assigned to the criminal investigation brigade forensic doctor as soon as he entered the sub-bureau.

He is a little shy, but he is very careful.

Earlier, I heard of Liu Yu's name, and in less than a month, he even solved four major cases.

"Good."

Half an hour later.

Xiao Tao's face was serious: "Yao Da, Brother Yu, there is cyanide on the bullet."

Yao Mutong paused, turned his head to look at Xiao Tao, and then looked at Liu Yu.

"How did you find out?" Yao Dachao asked Liu Yu.
