Du Xuan hasn't slept well for a few days, and since joining the firm, he hasn't made any substantial contributions, which his self-esteem does not allow, but fortunately, what he has worked so hard to develop has been completed!

After he packed his things, he came to the office, and as soon as he opened a box, Qiyu was attracted to him!

"Wow! what is this?" Qiyu found two silver pistols in the box, and couldn't wait to play with them in her hands.

But the weight of the body is noticeably heavier than that of other pistols, and the barrel is a little longer.

It wasn't too difficult for Qiyu, a former agent, to master it, but it was quite competent.

After Qiyu looked at the two pistols, loaded, disassembled, triggered, and reassembled, this set of smooth operations, Hugo was amazed: "Wow! so handsome!"

"The twin guns that I built for you! each one has a capacity of twenty-five rounds!" As he spoke, Du Xuan handed over ** and a bullet.

"Awesome! My biggest headache is to change **, wow! This bullet is still redesigned? It's so small!" After speaking, Qiyu ran towards the shooting range excitedly.

Du Xuan hadn't finished explaining the problem of the pistol, but he was no longer verbose, and glanced at Qiyu's back meaningfully, as if to say, "You'll know if you try it...."

"Didn't you prepare anything for me?" Qin Lin stood up from his chair.

Du Xuan didn't sell it, and took out one thing from the box.

It's a silver vest, it's very light, and it's very nice to the touch, and when you touch it, you can feel a thin layer of hard stuff inside.

Hugo observed, and the more he looked at it, the more familiar it became: "This.... Is it body armor?"

Du Xuan snapped his fingers: "Bingo! That's right!" After that, he looked at Qin Lin and explained: "Do you remember that piece of metal from the Guangji Society? I copied some! After a comprehensive experiment, I found that the strongest effect of this metal is bulletproof! Don't look at it, it's a thin layer! Even if it's that kind of large-caliber bullet that can destroy the human body with one blow, it can be blocked by it!"

"Not to mention any cold weapons, this is a real golden silk soft armor! It can save your life at a critical moment!"

After Qin Lin put it on, he felt very comfortable and did not affect his daily life at all.

Du Xuan continued: "Although most of the metal in this is imitated by me, it is enough!" and then pointed to Qin Lin's left chest: "That genuine piece is responsible for protecting your heart!"

It turned out that the piece of metal Du Xuan had been kept.

Qin Lin checked it, and indeed, the metal substance on his left chest was obviously thicker.

"Genius is genius! sooner or later something more awesome than the Luminosity Society..."

But without a word of praise, Qin Lin suddenly reacted: "No, you're looking down on me?!Why is Qiyu's attacking pistol and mine's life-saving vest?"

Du Xuan laughed twice: "When you practice marksmanship these days, I am also watching, okay? As far as your marksmanship is concerned, it is still a little far from Qiyu! Those two guns are a bit wasteful for you.... Or is this suitable for you, if you die, who will give me research funds?"

"Your uncle's!" Qin Lin knew that the other party was joking, but the truth was indeed as Du Xuan said, his marksmanship was not as good as Qiyu.

"However, I don't think there is anything special about those two guns, just the barrels are longer..." As soon as he finished speaking, the sound of gunfire came from the manor's training range.

Just listening to the sound, Qin Lin felt that something was wrong, and the gunshot was a little too loud.

Driven by curiosity, the three of them walked to the shooting range.

Qiyu was engrossed in shooting, trying to get used to the two silver pistols as soon as possible, and in the continuous firing state, the target in the distance was full of dense small bullet holes.

"It's nothing special...."Qin Lin looked at the target, the slight difference was that the bullet was smaller, and it was estimated that Du Xuan specially designed it in order to increase the capacity of **.

Du Xuan just smiled and said nothing.

"Hehe, there are two kinds of bullets!" Qiyu finished speaking, and replaced it with a bullet with a sharper warhead.

Then, instead of aiming at the target, she aimed at a thick, half-meter-high rock next to it.

Bang!

The stones were completely shattered! Looking at the stone fragments on the ground, Qin Lin reacted, this is indeed something that ordinary bullets can't do!

"A good horse with a good saddle, without these two guns as carriers, this bullet is also useless! However, this kind of bursting bullet is very powerful, and it is not very easy to do, so save some use...."Du Xuan reminded.

"Except for being a little louder, the others... Perfect!"

Two kinds of bullets, one large and one small firepower can be used flexibly, and Qiyu can't put it down.

Du Xuan was very impressed by this kind of praise, and said with a smile: "Don't worry, there is still a lot of room for improvement, take your time...."

..............

The last case aroused widespread sympathy in society, and Qin Lin's name began to become known to everyone.

This consultant has also gained a large number of fans in the police station, but these do not make Qin Lin happy, he cares more about the hidden ability of the system.

Therefore, he was required to notify him of all cases received by the police station so that he could participate in them. Only five days later, a strange case found Qin Lin again.

The meeting took place in the Sheriff's office for Wells. After reading the autopsy report, Qiyu said strangely: "What does it mean that it is impossible to determine whether the deceased committed suicide or homicide?"

Qin Lin squinted at Wells: "This forensic doctor is a half-ass?"

Wells hurriedly explained: "No, no, no! After experiencing the lesson of the last time, Deputy Director George has learned from the pain! He has hired a full-time forensic doctor with a lot of money, please rest assured!"

The photographs show that the fatal marks on the neck of the deceased were caused by hemp rope, and it is indeed difficult to tell whether the strangulation marks were suicide or homicide.

After Qin Lin saw it, he nodded with satisfaction, feeling that this new forensic doctor was quite reliable.

"It cannot be ruled out that after he was killed, he was disguised as a suicide!" Qin Lin lit his cigar: "The information of the deceased?"

Wells stood up from his office chair: "The conference room should be ready!"

In the conference room, the police officer who had already done the preliminary investigation got up and reported: "At about half past ten this morning, we received a call from a woman who said that someone had died. The location was an apartment on Hurrington Street. ”

"The woman didn't reveal her identity, she didn't tell us how she found the deceased, and she hung up the phone, and the call was from a phone booth!

Qin Lin lit his cigar: "Tell me about the situation." ”

The officer nodded, and immediately turned on the screen in the conference room.
