"Han Kuan said," Wu Xiumin said, "In the last year of graduation, the school will arrange internships for students. According to the prior arrangement, he should return to the Golden City Oil Company for an internship. However, because of problems in the formalities, Han Kuan needed to apply for a work permit and could only wait until the second half of the year to take up his post.

Originally, Han Kuan planned to go back to the Golden City to wait first, but he happened to meet a teacher named Lang Xiangyang. After Mr. Lang retired, he and his friends opened a sales company to sell teaching equipment and equipment in the northward relocation area.

Mr. Lang saw that Han Kuan was honest and smart, so he invited Han Kuan to help him in his company and promised to pay him a generous honorarium.

Han Kuan had nothing to do, and secondly, he saw that the remuneration was good, so he followed Mr. Lang and others to the north.

Han Kuan said that there were several other classmates who went north with them, but they were not in the same class. At that time, he was mainly responsible for equipment installation and maintenance, although the work was very hard, but he did earn a lot!

"It's just that after half a busy year, his work permit was completed, and he had to decline Mr. Lang's kindness, quit the job, and went back to work at the Golden City Petroleum Company!" Wu Xiumin said, "But not long after he went to work, what he wrote was published in magazines, and he also got the opportunity to publish and got a lot of money." He saw that the work of the oil company was not going well, so he simply quit his job and became a full-time writer!

"Team leader, I asked carefully," Wu Xiumin said seriously, "Yingping, Guang'an, Changping, and Beiqian, as long as there is a place where the demon case occurred, Han Kuan has been there, and all of them are within the time period of the crime......! The odds that Han Kuan is the real murderer of the demon case are really too great! But on the other hand, his confession is very unusual, if he is really the murderer, he should be able to hide it!"

"These ...... Did Han Kuan say it himself?" Zhao Yu also felt that Han Kuan's confession was very strange and very awkward......

"Yes!" Wu Xiumin said, "As soon as he came up, he deliberately emphasized the word SARS, saying that he had been working in the northward migration area during the SARS period! Team leader, he was clearly deliberately insinuating something, you say, is this Han Kuan deliberately provoking us? Or is it ...... What's the trick?"

"That'...... What about Zhang Jingru?" Zhao Yu asked, "What did Han Kuan say about Zhang Jingru?

"I don't know!" Wu Xiumin said, "Han Kuan said with certainty that he was introduced to Zhang Jingru in the Golden City. Zhang Jingru went to a postal school in Changfeng, although he went to school later than Han Kuan, but the postal school was a three-year system, so they happened to be assigned jobs together.

Also, Han Kuan also said an important piece of information. Zhang Jingru once mentioned that in the year of SARS, because of the serious epidemic in the northward migration area, Zhang Jingru's parents let her go home early. Therefore, when SARS broke out, Zhang Jingru was not moving north, and because of this, the two of them had not met in the northward migration area!"

"Huh?" Zhao Yu was surprised, "Not here?"

"So......" Cui Lizhu shook her head, "Zhang Jingru has nothing to do with the demon case?" However, the demon portrait on Zhang Jingru's document ...... Oops, what a mess......"

"I'm afraid that Han Kuan will lie, so I called Zhang Jingru's brother overnight!" Wu Xiumin said hurriedly, "Zhang Jingfeng did prove that this news is true, during the SARS period, Zhang Jingru did return to his home in Golden City, and then waited until the epidemic was over before returning to Changfeng."

"Later, I asked about the demon case again," Wu Xiumin continued, "Han Kuan said that he had never heard of it when he moved north, and it was only after the news hype that I learned about it! I noticed his reaction, and he was very calm, and his composure was beyond the reaction of a normal person......

"Oh, that's right, and there's another very incredible thing...... Wu Xiumin stabilized his excitement for a while, and then said, "I asked Han Kuan to tell me which units or schools he went to when he moved north to work?" He said that he couldn't remember the specifics, but he only remembered one or two, and then he told me the name! Among them, there was Guang'an School for the Deaf and Dumb!"

"Oh......" Zhao Yu was familiar with the information of the demon case, and immediately responded, "One of the deceased in the demon case is a teacher at the Guang'an School for the Deaf and Dumb!"

"That's right, that's right!" Who knows, after Zhao Yu finished speaking, Cui Lizhu suddenly remembered something, and hurriedly said to Zhao Yu, "Boss, I remember! Did you see this teacher......?" It's a bit similar to Li Fei's headless female corpse case?"

"The headless female corpse case, why ...... it" Zhao Yu was already dizzy and didn't know why.

"The demon case may not be limited to school bullying!" Cui Lizhu spread her hands excitedly and said, "It's not just the students who bully the students! It may also be the teacher bullying the students, the deceased is a teacher in a deaf-mute school, isn't it, just like the headless female corpse case, he angered the murderer because he bullied those deaf-mute students, and was targeted by the murderer! This is very similar to Li Fei's motive for killing back then!"

"Look at ......," Cui Lizhu said dancing again, "The shop owner in her 50s may have bullied the store employees! The old lady in her 60s may have done criminal deeds such as touching porcelain! Therefore, the murderer of the demon case is not just complaining about the victims of school bullying, but against all injustices! This person pretends to be a demon and kills people, in fact, he just hopes to use the power of the devil to crush the oppression in the world, this person ...... Who is he? really...... Is it Han Kuan?"

"If it is as you say......" Wu Xiumin muttered, "then the murderer should at least be someone like Li Fei......! All of Han Kuan's psychological traits are completely inconsistent with Li Fei!"

"The key is ......," Zhao Yu frowned and said, "Han Kuan's confession is ...... It's so easy! There's obviously something wrong with that!"

"Wow!" Suddenly, Cui Lizhu couldn't help but exclaim again, and said excitedly, "You say...... Will...... Han Kuan is not the murderer of the demon case, but a person who is very familiar with Han Kuan? For example, his classmates and the like, this person complained about Han Kuan, so he killed that old melon in Yaoming!?

Then, this mysterious murderer also followed Han Kuan to the north...... Wherever Han Kuan goes, he kills him? The real culprit of the demon case is actually this shadow killer!?"

"This ......," Zhao Yu smacked his lips and said, "You slow down, Xiao Cui, let me think about it...... If there really is such a shadow killer, then there should be a similar case to the Demon Case in Golden City?"

"Golden City ......" Wu Xiumin immediately said after hearing it, "I...... I'll call Ba Chen and ask them to check it out!"

"My God......" Cui Lizhu's big eyes revealed great horror, "Kill wherever you go, if that's the case, you have to ...... How many people have to die?"

As soon as these words came out, the atmosphere in the ward became even more eerie.

"You, shut up Lao Tzu!" Who knows, suddenly, Zhao Yu suddenly yelled at Cui Lizhu, and after Cui Lizhu shut up, he calmed down and said to Wu Xiumin: "Sister Wu, first, send me the video of your interrogation last night!"

"Second, check if there are any cases similar to the Demon Case in Golden City;

"Third, write out a detailed document on the case of Han Kuan and the demon, and then submit it to the Criminal Department to apply for a formal arrest warrant. Based on the information we have now, we can definitely leave Han Kuan at the police station! In any case, he is the biggest suspect in the demon case!"
