At 3 a.m. local time, a construction site in Yongbong-dong, West District, Gwangju City, South Korea.

The sky was covered with dark clouds, and the moonlight appeared and disappeared from the dark clouds, reflecting on the dark buildings, forming a gloomy and oppressive color.

A low, sharp wind blew through a cluster of buildings, and there was a whistling sound as it passed through some of the narrow cracks in the walls.

"Oh...... Oh......"

Just 5 floors above a certain building, a woman in silk pajamas woke up from a coma and let out a moan.

She vaguely remembered that last night, she had taken a shower in her own house and was about to go to bed. But suddenly a dark shadow appeared behind the curtain, and then he didn't remember anything......

I'm ...... This is......

After waking up, the woman's eyes were misty, and she tried her best to observe the environment, but it was pitch black in front of her, and she could only feel a cool breeze blowing.

However, perhaps out of some natural instinct, the woman has realized that she seems to be on a high place.

"Giggle......

The woman was trying to wake up, but from behind her came a burst of mad laughter, and the woman was so frightened that her scalp was numb and her legs went limp.

In the next second, a green light came from where the laughter came, and the green light flashed and flickered, dark and empty, and it was terrifying......

"Ah...... Ah......h

The woman shuddered and turned her head, and when she could see what was behind her, she almost fainted with fright!

But a few meters away from her, there was a green glow standing - the devil!

The devil had fangs, his eyes were bloodshot, and his appearance was terrifying, and now it was dancing its teeth and claws, and it was approaching him step by step......

"Ah!!h

The woman screamed in fright, got up from the ground haphazardly, and instinctively ran out in the opposite direction to the devil......

However, she had only run a few steps, but by the misty moonlight, she suddenly saw that she had run to the edge of the building, where there was no fence, and if she ran any further, she would inevitably fall from the building.

"Huh!?"

The woman exclaimed again, and had to stop from the side of the building, and almost planted downstairs.

"Whew...... Whew......"

The woman gasped for breath so quickly that her heart was about to jump out of her throat, she stood on the edge of the building and hesitated, because she couldn't judge how high it was, she naturally didn't dare to jump down!

However, at this moment, the demon behind him suddenly sped up and rushed behind the woman, and then stretched out his arm and pushed hard, and the woman fell directly from the stairs......

"Ah......h

A woman's exclamation was heard underfoot, but the exclamation was quickly replaced by the sound of falling to the ground, and with a muffled bang, the downstairs instantly returned to silence, and no other sound could be heard except for the sound of the wind, which was still whistling.

At this moment, the demon standing on the edge of the building stopped shaking, and with a hula he ripped off his mask, revealing the face of a cold man:

"Ahsi......" the ghost man said in arrogant Korean, "it's all a lie, she won't jump down by herself......!"

......

......

The next morning, in the office of the Yaoming City Police Department, Zhao Yu's excited roar was heard:

"Got it, I finally got it!hahaha...... Haha......"

Wow, Wang Can, who was lying on the table, was startled, first fell down, and then got up from the ground, rushed to Zhao Yu and asked:

"Master, do you understand, what do you understand?"

"Hahaha......" Zhao Yu took a large stack of materials, excitedly grabbed Wang Can's collar, and said with wide eyes, "Your master's retreat cultivation is not covered, Lao Tzu has finally figured it out now!"

As he spoke, Zhao Yu pointed to a certain position on the whiteboard, and then said heavily: "If my guess is right, the problem is - here!!"

"Oh?" Wang Can looked at the whiteboard and wondered, "Isn't this Nanhai Prison?"

"Boy," Zhao Yu said through gritting his back molars, "I can guarantee that the real murderer of the murder memoir is someone here - the prisoner !!"

"Ahh......h......h ......Why? So what?"

"That's because we were tricked by him before! Look at it......" Zhao Yuyi took a photo of Guihai Prison, "the real murderer has either been released recently, or ...... It's just that it's still honestly locked up there!"

"What you said ......" Wang Can turned into the second monk and shook his head vigorously, "If this is really what you said, shouldn't this case have been solved long ago?"

"You say we're fooled, this person...... How the hell did you fool us?"

"Hahaha......" Zhao Yu laughed heartily, and kept laughing for more than ten seconds, before continuing, "If you want to hide from me Detective Zhao, he is still a little tender!"

"Boy," Zhao Yu shook the information in his hand and said to Wang Can, "The murder memoir is just a cover for the murderer! He exposed so many murder cases under the pretense of Nong Zhifa, but in fact, it was not for some kind of show-off for him!

"It's, it's ...... To cover up ...... His real crime! He was forced to do it!"

"What did you say," Wang Can became more and more confused the more he listened, "I have no choice?

"My speculation is like this, only this explanation can make all our previous inferences valid," Zhao Yu pointed to the information in his hand, saying that it was the information, but in fact, it was all written and drawn by Zhao Yu last night, "You see......

"Let's say the real murderer is a serial killer who has committed multiple homicides, but has never been discovered by the police!

"But, unfortunately, he missed a certain murder and was sent to prison!, I guess......" Zhao Yu said a little mysteriously, "this person should not be sentenced to death or life imprisonment for the crime he committed, maybe only for a few years for the crime of wounding......

Otherwise, there would be no need for him to die anymore......

"Well, I'll assume that this person is X," Zhao Yu pointed to the X number on the white paper and said, "Let's say X also went to Nanhai Prison and was in the same prison as Nong Zhifa."

"Think about it," Zhao Yu said, "X himself is a serial killer, so he must be worried that the police will dig up information about his previous crimes and reveal his identity through his imprisonment!"

"Then he's really finished!

"And at this time, he suddenly met Nong Zhifa...... "Zhao Yu said, "X may have been engaged in psychology-related work or study, and mastered certain skills, so after seeing Nong Zhifa, he quickly brewed a good way to divert the attention of the police, and wanted to use Nong Zhifa to get rid of the police's attention to him!"

In particular, after he found out that Nong Zhifa's life trajectory was somewhat similar to his previous life trajectory and that he was already terminally ill, he was even more determined to make this plan......

Therefore, he took the initiative to contact Nong Zhifa, brainwashed him, hypnotized him, and then imposed the identity of the serial killer he made up on Nong Zhifa, making Nong Zhifa think that he was a serial killer!

"And next, is the most critical place...... Zhao Yu paused and said with an oath, "He didn't instill the original cases he committed to Nong Zhifa, but changed a lot of content, so that we can't compare all the cases until now......

"Boy, do you understand now?" Zhao Yu asked Wang Can seriously, "These altered contents are the key !! of the murder memoirs."
