At 3 a.m., the headquarters building of the 5th Security Management Section, located in the east of the northern middle floor, is located in the office of the section chief on the 11th floor.

Jean quietly stared at the several bombs that had been listed on the screen, chemical bombs are the easiest to make, only need to be mixed according to a certain ratio, placed in a fixed place, as long as the chemicals inside will explode after drastic changes, the range of impact within 20 square meters has a strong lethality, and if some toxic substances are used as diffusers, there is a possibility of large-scale poisoning.

The second is the sonic bomb, which requires complex mechanical principles to make, but the 2nd Branch has given a clear speculation that the enemy may master this technology, once the infrasound wave spreads out in the crowd, it will lead to direct death in serious cases, and the lightest ones may burst the blood vessels inside the body, causing vomiting and deafness.

The third is the aerodynamic bomb, there are many types, under today's technology, this aerodynamic technology is not difficult, the underground transportation pipeline is aerodynamic technology, only need to make a good aerodynamic core, fill in the explosion splash around the periphery, such as sharp needles, marbles and other metal objects with strong lethality at close range, if it explodes in the crowd, it will cause mass destruction.

The last one is the bomb in the light killing weapon, those places that modify the corners of people's eyes, there are more or less high-intensity light killing weapons, this kind of weapon will make people blind directly, and the harm is definitely no less than the others.

As many as 189 points with raw materials have been found, and a larger investigation will begin tomorrow, and prevention has always been a priority for the department, Jean turned off the light and shadow panel on explosives and called up a light and shadow panel, which has already recorded 13 homicides that occurred in District 1 around 8:20 last night.

Click

The door of the room was opened, and Qin Dong walked in with a smile.

"Lord Jean, aren't you going to rest yet?"

Jean smiled and lit a cigarette.

"Those guys won't let us rest."

Qin Dong smiled and called up a light and shadow panel.

"You go get some rest early."

Qin Dong shook his head and began to call up a large light and shadow panel, which listed the scenes of 13 homicides and a large amount of information.

"Lord Jean, in addition to the case that Secretary Le Xiao prevented, there are as many as 500 people involved in the 12 cases, and it is very difficult to investigate them one by one, the only thing that the killing methods of the 12 incidents are the same is the use of the blind spot of the surveillance, and the distance to the target person, they are all kills with one hit, and the killing tools used are poisons, weapons, ropes, stones, etc., all of which are very routine killings, but if you connect the events, the time point around 8:20 is the time when the 12 victims died."

Jean nodded.

"There is no physical evidence, there is no surveillance, everything is planned, within 1 kilometer, can the suspects who can complete the crime in 5 minutes be listed?"

Qin Dong immediately called up a piece of information, looked it up for a while, and then shook his head.

"You have to find out from these more than 500 people who are related to the victims, and as for the tools they used to commit crimes, it is difficult to find the source."

Drip, drip, drip

This will be a light and shadow screen pop up, it is an urgent arrest warrant sent by Mo Xiaolazi, which requires the cooperation and coordination of the 5th section and the signature of the section chief.

After Qin Dong looked at it for a while, he was a little frightened, this kind of compulsory arrest warrant is not in accordance with the law, because it is just a suspicion, the matter is still in the investigation stage, a total of 56 people have been arrested, Qin Dong checked them carefully, and none of them had any illegal records.

Jean directly took out the phone and dialed Mo Xiaolazi's phone.

"Even if you ask the murderer, you still can't solve the problem behind it."

"It's true, but everyone else has been bullied to the end, and now the General Affairs Section is busy in order to cope with tomorrow's press conference, and the people in the other sections are not idle, since these brainless guys have been bewitched by the rioters, then we naturally have no reason to be polite to them, hurry up and sign, I will let these guys vomit in 1 day at most."

Jean looked at the 13 killings again and said after a moment.

"According to the process to investigate, what needs to be dealt with now is the matter of explosives raw materials, investigate everything about the dead prisoner, you can always dig up something, I can issue a reward here, as long as you provide effective information, 100,000 a piece, your approach has been too radical recently."

Mo Xiaolazy giggled and snorted coldly.

"Haven't you seen what happened tonight? I'll pass it on to you later, I'll listen to you for a while, and take a gentle approach, and now I've basically guessed the murderers in 8 of the 12 murders, and I really want to bring them over directly and let them have a good time, after all, I'm about to go crazy with the constant increase in our workload. ”

After a while, Jean's mobile phone sent a video of the scene, as well as a scene that happened on the avenue leading from District 2 to District 3, Jean looked at everything on the screen helplessly, and Qin Dong's eyes widened on the side.

"Master Jean, this guy ........"

"When Nia comes to work, I'll investigate this murder myself."

Jean stood up, and Mo Xiaolazi, who was on the other side of the phone, laughed.

"Such a small case doesn't fit your character, why do you suddenly want to investigate it yourself?"

Jean smiled, lit a cigarette and exhaled a puff of smoke.

"Since the other party has sent out the challenge book, and the 13 subjects have already received the challenge book, I will personally do it for me and continue to complete the challenge given by the other party."

.......

In the darkness of the night, with a slight noise, Quasimodo opened his eyes, and Billy, who was holding his arm, stood up with a wicked smile on his face.

"I'm sorry to wake you up."

Billy said softly, everyone else had already slept, the wise and Leng Rui were in the other bedroom, Le Xiao was in the room opposite Jean's bedroom, and Quasimodo and Billy directly got the blankets and slept in the living room.

"Don't hurt...... The kid. ”

Quasimodo's voice was no longer gentle, and it seemed a little heavy and deep.

Billy smiled and bowed.

"Rest assured, Mr. Quasimodo, that child is my savior, if I really hurt her, you will kill me, right?"

Quasimodo didn't speak, just stared at Billy with cold eyes, he walked up slowly, looking at Quasimodo's puzzled eyes, he turned around and said.

"Go see an acquaintance."
