In a ruined building on the banks of the Tama River in Tokyo, there is a chilling feeling in the silence of the night, accompanied by the cries for help of girls and the wheezing of men.

After a long gasp, a young man climbed up from the girl's body and slowly lifted his pants. The girl's hollow eyes and the torn shredded sailor suit on the scene clearly illustrate what is happening here.

"It's a pity, I would have liked to have spent a few more days with you, but unfortunately your family is no longer planning to pay the ransom for you. Did you see, I've only received this amount of money this month!"

As he spoke, the man took out an envelope from his pocket, then opened the envelope and took out two brand-new Fukuzawa Yukichi cards from inside, waving them at the girl.

The girl felt unprecedented fear under the man's crazy actions, she tried to get up, moved her body with her hands and feet, and crawled backwards, trying her best to avoid the man.

Unfortunately, these actions were all in vain in the eyes of the man, he walked to the schoolbag he threw aside, unzipped the schoolbag without hurry, and then groped out some hardware tools from inside. Includes a hand saw and a round-headed blast hammer. Then he took out a disposable raincoat from his schoolbag and put it on himself. Immediately after, he picked up the blast hammer and walked towards the girl step by step.

"Don't ...... Beg...... Please, I promise my family will continue to give money...... Please don't be angry......"

The man raised the hammer in his hand and swung it at the girl mercilessly.

Boom!

"Ah...... Sorry ......"

Twice, boom!

"Ask for ...... You"

Three times, boom!

"Seeking ......"

……

"It's so laid-back!"

Early in the morning, Section Chief Matsuda, who habitually went to the special search department to drink coffee, saw at a glance Lin Shuichi who was playing shogi with the computer, and Miki, who was sitting opposite him and reading seriously.

"How about it, how many games have you won?" Section Chief Matsuda, who had poured the coffee, walked behind Lin Xiuyi and watched the battle with great interest.

"I felt quite interesting when I first learned to play, but so far, I haven't met an opponent worse than me!" Lin Xiu said as soon as he turned to Matsuda.

"Did you hear?,The sex crime 2 department where you used to work seems to be in some trouble.,Just now I saw Kuwajima-kun coming out of the criminal minister's office.,That look is really sympathetic!"

"What happened?" Lin Xiuyi asked curiously, today was the first day he came back to work after going to Aomori Prefecture for the funeral, so he still didn't know anything about what had happened during this time.

Just when Section Chief Matsuda was about to tell Lin Xiuyi the inside story, two colleagues suddenly came in at the door. As soon as they entered the door, Section Chief Matsuda immediately coughed and stopped himself.

Lin Xiu turned his head and saw that the person who came was none other than his former subordinates, Hanagata and Aizawa.

"Section Chief, Police Department!" Aizawa and Hanagata saw Lin Shuichi and Matsuda and quickly bowed to the two. Section Chief Matsuda nodded, seeing that the two of them should have something to discuss with Lin Xiuyi, so he asked Lin Xiuyi to say goodbye very interestingly, and when Section Chief Matsuda left, Hanagata and Aizawa immediately sighed and complained to Lin Xiuyi.

"Police Department, please help us this time!" Aizawa and Hanagata bowed deeply to Lin Xiu, and then asked helplessly.

"What's going on!" Seeing Hanagata and Aizawa's performance, Lin Xiuyi asked strangely. At the same time, Miki also stood up and poured a cup of coffee for each of them.

"Actually, it's like this, we have a case in our hands, and something has happened recently, just now Minister Sato called the Kuwashima Police Department and asked us to solve the case within a month......

Hua Xing said to Lin Xiuyi with a sad face, while Aizawa frowned, and it could be seen that the two of them were really under a lot of pressure!

"Oh, then you are here to let me assist you?" Lin Xiuyi asked the two curiously.

"Yes, we all admire your methods of solving the case very much, and if we can have your assistance, we are confident that we can arrest the murderer within the specified time!" replied to Hanagata to Lin Xiuyi.

"But, did you come to me and discuss it with Kuwashima seniors?" Lin Xiuyi asked the two again, Lin Xiuyi and the Kuwashima Police Department had dealt with each other when the Sexual Crime Investigation Department 2 was handed over. The relationship with Fang is not bad, so he doesn't want to meddle in the case of the sex crime investigation 2 behind the back of Kuwajima's seniors, so as not to cause dissatisfaction with the other party.

"It's okay, that's what I mean, Xiu Yijun, I really want to ask you this time!" Just when Lin Xiuyi was understanding the situation with Hanagata and Aizawa, Kuwajima's seniors from the Sex Crime Investigation 2 Department also rushed over.

As soon as Lin Xiu saw the senior Kuwajima standing at the door, he quickly got up and beckoned the senior Kuwajima to come in, and after Miki arranged a seat for the senior Kuwajima, he casually closed the blinds of the special search department.

"It's hard to put into words! Actually, it's my fault, if only I had paid more attention to it!" Kuwajima said ashamedly, picking up the coffee he had in hand and taking a sip.

"I think it was half a year ago! I was still working as the head of the criminal department at the Kichijoji Police Station. It happened that there was a case of missing persons, and the other party was a female student at a middle school in Kichijoji, and it was her mother who came to report the case. At first, I took this case very seriously, but later, as we gradually investigated, we found that this girl had run away from home several times, the longest of which was even more than half a year. That's why I'm not continuing to pay attention to this case......"

"Do you mean to give up on continuing the investigation at that time?" Lin Xiuyi asked puzzled, with his understanding of the Sang to the police department, the senior of Sang Island should not be such an irresponsible person.

"Well, it's my fault, I still had a burglary case to investigate at the time. We didn't have the energy to take care of the missing person's case, and according to the results of our investigation at the time, the girl had run away from home several times, and shortly after she left home, she also sent a text message asking for living expenses and photos, so we all thought that this was just another runaway from home by this girl, and she would come back soon, and we didn't pay attention to it at all. ”

Sang to the police department lowered his head and said to Lin Xiuyi dejectedly.

"So, what happened?"

"A few days ago, we found a human arm in the grass near Asakusa Park, and it can now be confirmed that it belongs to the girl. ”
