I immediately got serious from a short period of relaxation, and hurriedly rushed to meet Nangong Yi and them, so that the fingerprints on the bell tower could be extracted and compared Originally, I just wanted to finally determine that Li Hejun was the murderer, although he confessed everything before jumping off the building, but many details disappeared with him.

But the result of the comparison is so surprising, since there is no Li Hejun in the three sets of fingerprints, it can only mean one thing, Li Hejun may not be the culprit of the five murders, and the real murderer has always been at large.

I just met Nangong Yi, she looked more anxious than me, put a stack of information in front of me, and said to me in disappointment that she should have found the wrong person in the detection of the 403 dormitory and Qiao Kewei's murder case, and after learning that there was no Li Hejun's fingerprint in the three sets of fingerprints, Nangong Yi immediately retrieved Li Hejun's file.

According to the above records, Li Hejun is indeed a first-class hypnotist, and he is also involved in psychological behavior hypnosis, and Li Hejun does have the ability to manipulate people's subconscious meaning through psychological suggestion, but Li Hejun does not have the ability to hypnosis for a long time.

Nangong Yi pushed a certification certificate in front of me, this is a standard for hypnotist assessment, one of which is hypnotic time, and Li Hejun shows in this item that the hypnosis time he has can only last fifteen to thirty minutes, but from the time Nie Bingwan and the four of them appeared in the monitoring to the final death, the time in between is three hours, such a long period of mind control can only be completed by a master-level hypnotist, but Li Hejun definitely does not have such a super hypnotic ability.

After listening to this, I frowned and walked back and forth in the room for a few steps, so it seems that everything is an illusion arranged in advance, including Li Hejun, who is also a manipulated pawn, and the only purpose of his existence is to make us mistakenly believe that he is the murderer, so it can be seen that Li Hejun was the one who was destined to die from the beginning.

The so-called love murder is also fake, the real culprit should be very clear about the unknown relationship between Li Hejun and Nie Bingwan, and it is by using this to successfully mislead us, it can be seen that behind the murder that happened in the 403 dormitory and the murder of Qiao Kewei jumping off the building, there is also the truth that we have never touched.

"Are there any people in Hede Medical College who have the ability to hypnosis for a long time?" I turned around and asked thoughtfully.

"No, all those who have such mind control abilities are master hypnotists, I have checked the information, and there are no more than five people who have the ability to complete the kind of subconscious control in Nie Bingwan's murder case." Nangong Yi shook her head and replied with certainty. "Four of them are abroad."

"One more person in the country?" Han Yu raised his head and asked seriously. "Who is it?"

"An Rongyue, female, fifty-three years old, a super-level psychological hypnotist, is definitely one of the leading authority figures in this field, if you want to compare Li Hejun's hypnotic ability with her, it is simply the difference between a primary school student and a doctor." Nangong Yi replied.

"Since An Rongyue is in China, does she have time to commit crimes?" The prince asked calmly. "Or is there any intersection between An Rongyue and Hede Medical College?"

"There will definitely be no time for An Rongyue to commit the crime, this person can be completely ruled out, but she really has an intersection with Hede Medical College." Nangong Yi nodded and replied calmly. "And An Rongyue has been at Hede Medical College until now."

"Ahh Didn't you just say that no one in Hede Medical College has such ability? Han Yu was stunned for a moment and asked what I wanted to ask.

"An Rongyue is not a teacher at Hede Medical College, but a patient here." Nangong Yi replied unhurriedly. "She suffered mental frustration because of emotional problems, and after losing control, she used hypnosis to brutally kill many people in a row, since she found out that her boyfriend was cheating, An Rongyue couldn't tolerate betrayal and killed her boyfriend, and since then she has been hunting and killing men who have been abandoned from beginning to end, if she is not sick, I believe it will be difficult to be caught, and she is still admitted to the ward in the basement of Building 19 of Hede Medical College."

I nodded thoughtfully, An Rongyue really can't have the possibility of committing a crime, a dangerous patient like her, I think in Jiang Xinyu's eyes, the degree of important prevention will not be inferior to Xu Wanjun, once a person like An Rongyue leaves the ward, the consequences are unimaginable, and it doesn't make sense at all, since she has the ability to leave the basement ward, why go back.

"Presumably you have already compared the people corresponding to those three sets of fingerprints, who are they?" I looked at Nangong Yi and asked seriously. "If our inference is correct, the real culprit behind all this should be among these three people."

"I have asked Hua Guanwen for the fingerprints of all the faculty and staff members of the school, and after comparing them with the three sets of fingerprints found on the bell tower, I have identified one of them." Nangong Yi replied calmly. "However, this person is the person responsible for the maintenance and repair of the bell tower, and he has sufficient alibi evidence on the day of the crime, and judging from this person's resume, there is no possibility of committing the crime at all, so it is ruled out."

"What about the other two?" Han Yu asked.

"The second set of fingerprints did not match all the faculty members of the Hopewell School of Medicine, and the person who left this fingerprint was not from the School of Medicine."

"That's strange, I remember Hua Guanwen said that the bell tower has always been an important place for the medical school, and no one is allowed to go up without permission, since it is not a person from the Hede Medical College, how can fingerprints be left on the bell tower?" I frowned and muttered to myself in surprise.

"I also deliberately looked for Hua Guanwen again for this reason, and he told me with certainty that in addition to the person in charge of maintenance, only Jiang Xinyu and him can go directly to the bell tower, but there is no him and Jiang Xinyu in the fingerprints." Nangong Yi looked at me and shook her head with some confusion. "As for why someone who is not a medical school appeared in the bell tower, Hua Guanwen is also as curious as we are."

"What about the last set of fingerprints?" The prince asked quietly.

"The last set of fingerprints is very blurry, and from the extracted lines, it should be that the fingers have been severely traumatized, so the fingerprints are blurry and cannot be distinguished at all."

According to the results that Nangong Yi learned, in addition to the excluded bell tower maintenance personnel in the three sets of fingerprints, the identities of the remaining two people are extremely suspicious.

Nangong Yi has informed the school that the investigation of the 403 dormitory and Qiao Kewei's five murders will be restarted because of new discoveries, but there is still no mention of Helianyi's matter, this should be a good opportunity, by investigating the murder of Nie Bingwan and others, and re-investigating the truth about Helianyi's suicide ten years ago.

My focus has slowly shifted to the tattoos on the soles of Nie Bingwan and He Lianyi, since the investigation of Li Hejun is the real murderer, the motive for Nie Bingwan and others to be killed is love murder has also been overturned, why did the five ordinary students suffer this catastrophe, and what secrets did they discover?

I think there must be other commonalities between Nie Bingwan and Helianyi, maybe as long as the truth of Helianyi's death is found, the murder case of Nie Bingwan and others will be solved, and the most urgent thing at the moment is that Zhong Hui still has three days, no, there will only be two days left after today, and she will leave here, no matter how Nangong Yi judges that she is telling the truth, even if she really didn't kill Helianyi, judging from her flickering reaction when she came into contact with us, Zhong Hui must have hidden something from us.

I don't think it will be so easy to let Zhong Hui tell everything as it is, although I have only met Zhong Hui a few times, but her temperament and pride can show that she is a very confident woman, and people like her must have a good psychological quality, otherwise I asked her like this today, and I didn't see Zhong Hui have a gaffe reaction.

"After Helian Yi's death, Kong Xianan and Zhu Jie both had inexplicable mental breakdowns one after another, but Zhong Hui was unharmed...... "I took out a cigarette and put it to my mouth and said thoughtfully." Do you remember Zhong Hui telling us that they see dead people and dissect corpses every day, and their psychological endurance is far better than ordinary people, and she also insists that Helian Yi can't have a mental breakdown because of seeing something terrible. ”

"Do you mean that Kong Xiannan and Zhu Jie's mental loss of control may be the same as Helianyi's, and they were subjected to more intense external stimulation to cause that?" Nangong Yi took my words and asked.

"I'm more concerned about why Zhong Hui is okay." I lit a cigarette and replied lightly.

"Hua Guanwen seems to have a high opinion of Zhong Hui, thinking that her psychological quality and ability to withstand pressure are stronger than the other three." The prince looked at me nonchalantly and said.

"Then it's troublesome, if a woman like Zhong Hui is determined to hide something, no matter what method we use, she won't tell the truth." Han Yu spread his hands and said helplessly.

"I have a solution." I took a puff of my cigarette and said meaningfully.

"What's the solution?" Nangong Yi asked.

"No matter how good a person's psychological quality is, there is a bottom line to bear, since Zhong Hui has a strong psychological quality, if she can make all her defenses fall apart in one fell swoop, she may be able to say anything."

"But what we currently have is the dictation of Kong Xianan and Zhu Jie, with the mental state of the two of them, even if they tell the truth, they don't have any legal effect, I think Zhong Hui is also very aware of this, relying on this has no effect on Zhong Hui at all." Nangong Yi shook her head and said gloomily.

"That's not necessarily, the reason why Zhong Hui can disagree is that she thinks that everything is already in the boat, but ......" The corners of Han Yu's mouth slowly curled. The biggest stimulation for her is to subvert what she thinks is the most unbreakable, Kong Xianan and Zhu Jie are crazy, but ...... Helian Yi is alive again! ”

I took a deep puff of cigarette and smiled faintly, Han Yu's shrewdness was undoubtedly revealed at this time, what he said was exactly what I thought, in Zhong Hui's heart, Helian Yi was a person who had been dead for ten years, and Kong Xianan and Zhu Jie's mental disorders made her firmly believe that even if there was a secret, it would not be known.

If Zhong Hui is asked to see Helian Yi who has come back from the dead, I think the stimulation and shock of Zhong Hui are self-evident, even if a person with good psychological quality is facing a person who has been dead for ten years and is standing in front of her alive, I guess if Zhong Hui has a ghost in her heart, no matter how strong the defense line in her heart is, it will collapse in an instant.
