Seeing that Ya Qi left calmly, he picked up the confetti on the table. Pen & Fun & Pavilion www.biquge.info got up and said, "Then I'm ...... too"

Before he finished speaking, he was decisively rejected by Ding Jialin: "Don't even think about it, you have to stay."

Yu didn't say anything, sat down quietly and continued to cut paper.

"Next, the eight of us split up. Song Yuanchao, you are in charge of rooms 1 to 13. Qian Jun, you are in charge of rooms 14 to 25. Song Xiaosheng, you are in charge of rooms 26 to 38. Lu Tie, you are in charge of rooms 39 to 50. …………。 Oh, you are in charge of rooms 76 to 88. I'll be in charge of the rest of rooms 89 to 100.

Do you have any objections? ”

"Since there is no objection, I continued. After the other party opened the door, just like Yu Feng said, he asked directly in an affirmative tone, striving to deceive the other party's true face, and also pay attention to the micro-expressions.

However, I think it is a bit risky to act alone, can I ask the police officers to accompany me for protection? ”

Zhang Zheng nodded without thinking about it and said, "Yes."

Officer Mu gave it a second look. In the end, all 11 police officers agreed.

Due to the disproportionality between the number of police officers and the number of detectives, only three detectives accompanied by two police officers, Lu, Ding Jialin, Song Xiaosheng, Zhong Gao, and Lu Tie were all accompanied by one policeman.

……

Back in the room, Ya Qi locked the door and lay on the bed and pretended to sleep. Silently calculating the time in his heart, he knew that it would not be long before someone would call him.

Tick tock......

The hands of the clock beat many times, and the doorbell finally rang.

At this time, more than 40 minutes had passed since the mission was issued, and there were still more than 11 hours left to solve the case.

Ya Qi didn't rush to open the door.

Jingle, jingle, jingle......

After a while, there was another knock on the door.

Ya Yi pretended to look lazy and tired, and walked to the door as he spoke: "Yes, yes, don't press it, come right away."

Click, Ya Qi opened the door, closed his eyes and asked, "Who?"

"Wind and dust, someone is dead."

Ya Mi responded lightly: "Oh, someone is dead."

Seeing that Ya Mi was absent-minded, Ding Jialin was a little angry, and shouted in a loud voice: "Please, please be sober, someone is really dead."

Ya Mi said in a daze: "I know, I know, twenty-two people died."

"It's not that, oops, I can't tell you, follow me and you'll understand. Wow, pull away. ”

After Ding Jialin finished speaking, she left, leaving behind an inexplicable look and a bud in a state of ignorance.

He looked at Ya Mi and hesitated for a while, then pulled Bud Mi and ran to Room 7.

Room 7, the room is in chaos, wardrobes, beds and other large objects are slightly displaced, the sheets and quilts are messily thrown on the ground, and on the desk and chair next to it sits a thinly dressed boy, his face is close to the table, his left hand is on the table and is gripped, as if he has held something, and his right hand hangs. At first glance, it was clear that the state was not optimistic, because the hair on the back of his head was completely dyed red, and the blood flowing from the back of his head slowly trickled down his back, soaking the man's white clothes.

Two meters behind the man, a man was lying with a dagger tattooed in his chest and holding the handle of the dagger in both hands. At its head, there is an iron rod stained with blood.

Upon examination, it was confirmed that both were dead. The overall layout of the room is like two deceased people after a fight, and man B hits man A to death with a stick, and then feels guilty or feels that the revenge has been avenged, and commits suicide with a knife.

But after carefully inspecting the things in the house, Song Xiaosheng easily saw through the layout of the murderer and confirmed that it was a homicide.

The reason was that the body was lying on the desk, apparently dead, holding something in its left hand. And Song Xiaosheng was pleasantly surprised to find an object in the house that matched the grip marks of the corpse, which was a booklet about quadratic functions, and the booklet was sealed with a conspicuous line of equations.

（x＋p）∧2＝f(r)

seems to be a very ordinary quadratic function equation, but in Song Xiaosheng's eyes, it is a death message that predicts who the murderer is.

Because f(r) is removed from the parentheses, it becomes fr, which happens to be the pinyin acronym of the offender, so the only thing that can be equated with f(r) is the name of the murderer.

However, when it comes to converting (x+p)∧2 to the name of the murderer, all the detectives have no clue. So, everyone remembered the buds!

Seeing that Song Xiaosheng was the only one in the room, Ding Jialin asked suspiciously, "Why are you the only one, and the others?"

"I'll let them continue with their assignments, and take everyone to the main hall by the way. After all, finding Gu Zhongmi is a big deal, and it can't be delayed because of this matter. ”

Although Song Xiaosheng said very reasonably, Ding Jialin was uncomfortable listening to it, frowned and asked, "How did you find out?"

"There was no progress, the evidence seemed to have been taken away or destroyed by the killers, and the only thing left at the scene was this math booklet. The next step is to see how to solve this quadratic function, and if it is solved, the case can be solved. ”

"Song Xiaosheng, why are you so sure that the pamphlet is decisive evidence. In my opinion, this is just an ordinary booklet. ”

Song Xiaosheng shrugged his shoulders indifferently and said, "Everyone has their own opinions, you firmly believe in your opinions, and I firmly believe in the absolute inspiration born from years of experience in the detective industry."

"Whatever you want, the detective is not a normal person."

"You're absolutely scolding yourself for that. Detectives, weirdos, you have it all. "Before the bud arrived, the sound came first.

Ding Jialin immediately turned around and said, "What's wrong, I'm normal!"

The figure of the bud appeared in front of the door: "Even you know how to use the word 'okay', can I still veto?" Uh, these two people are...... What's going on? ”

"Dead!" Song Xiaosheng replied calmly, raised the function booklet in his hand and said, "This is the name of the murderer, can you solve it?"

Ya Qi raised his forehead and said: "Oh no, your topic is too jumpy, I may not be able to react for a while, you should start talking about the cause of death of these two people!"

Song Xiaosheng was stunned for a second, and explained plainly: "The corpse lying on the desk was killed by a heavy blow to the back of the head, and the corpse lying on the ground was pierced by a sharp blade in the heart and killed with one blow."

Ya Qi nodded: "That's the case, I understand."

"Enigmatic comprehension." Ding Jialin said she didn't understand.

After pondering and analyzing for a while, he said, "Although the scene looks like two people fighting and dying, they were actually killed by the same person, and then disguised as they are now."

Ding Jialin smiled dryly and said, "Hehe, you actually understand a piece."

Ya Qi checked his pulse and asked, "So, who is this person lying on the table?"

Ding Jialin said frantically: "So, it should have been explained from here from the beginning......!" (To be continued.) )
