Zhan Zhao looked at these information one by one, and the more he looked, the more severe his expression became.

"Maoer, how about it?" Bai Yutang asked anxiously.

"Mouse, how did you find it?" Zhan Zhao looked up at Bai Yutang.

“…?…What did I find?”

"These people are related to obsessive-compulsive disorder and psychological hints." Zhan Zhao took the information to photograph him, "Speak quickly! Don't pretend to be stupid!"

"I didn't pretend to be stupid." Bai Yutang flipped through the magazine casually, "It's just that you think, this case is inexplicably related to you, and with that C-level psychology department, I think it has something to do with psychology."

"And!" Bai Yutang added, "Wang Chao and the others have read all these information in the past few days, but they have not found any special relationship between these victims. The only thing in common is that they are relatively disappointed in life, not very successful in their careers, and a few of them have mental illnesses."

"Oh~~" Zhan Zhao touched his chin, "so I came to me for inspiration, right?"

"I think you are already inspired." Bai Yutang reached out and raised his chin, "Look at your proud look."

"Go!" Zhan Zhao clapped his hands away, stood up and walked out.

"Hey! Cat! Where are you going?" Bai Yutang hurriedly followed.

"Do you know that our bureau was the first to establish a "Criminal Psychology Research Center"?" Zhan Zhao asked as he walked out quickly.

"Well... it seems that the Baoju proposed to be established twenty years ago?" Bai Yutang caught up with two steps, and the two walked forward side by side, "What does it have to do with the case?"

Zhan Zhao pressed the elevator: "Do you know why this department is set up?"

Bai Yutang cleaned his ears: "You're so pleased, can you say yes?"

"A big case happened that year. Due to the widespread involvement, most people don't know it. I also heard from my seniors when I entered the research center." The two walked into the elevator and Zhan Zhao pressed the button on the 11th floor. "No one knows the details, but only knows that the murderer controlled the murder through psychological hints. Hundreds of people died in five years, and more than a dozen police officers died."

The elevator door opened on the 11th floor, and Bai Yutang looked disbelief: "How could I have never heard of such a big case?"

Zhan Zhao laughed, raised his foot and walked towards the archives: "How old were you twenty years ago? Where can you ask for it?"

Bai Yutang rolled his eyes: "How did you know?"

Zhan Zhao smiled and glanced at him: "Am I older than you?" After saying that, he shook his head and looked at Bai Yutang with a gray face beside him, thinking, "I didn't know how cute someone was when he was a child. He called his brother so sweetly, but who knew that he would be so annoying when he grew up!"

Bai Yutang's eyebrows stood up when he heard this: "Ha! You dead cat, you dare to ridicule grandpa. Is it cute when I was a child?" After that, he recalled, "I don't know who the aunts in the kindergarten are kissed every day? "

"Ah!" Zhan Zhao quickly changed the subject, "The archive room is here!" After saying that, he pushed open the door and walked in

Bai Yutang followed behind and murmured: "If I hadn't protected you, could you grow up so old safely? Ingratitude!"

Zhan Zhao in front of him closed the door fiercely. Fortunately, Bai Yutang quickly looked and reached out to block the door that was coming towards him. Yu Jing patted his chest without hesitation: "You are too cruel, are you jealous of your nose handsome?!"

"Shh!" Zhan Zhao turned around and made a gesture of silence at him, then walked to the file rack and searched.

"How slow is this?" Bai Yutang was dizzy when he saw the dense tags. "Isn't it recorded on the computer?"

Zhan Zhao replied casually while flipping through him: "I have searched it before, but there is no record of this in the computer... Huh?"

Bai Yutang frowned and stopped when he saw him flirting, and hurried over: "What's wrong? Have you found it?"

Zhan Zhao pointed to the air and said, "There are a lot fewer files in 1982-87!"

"Those are secret files." An old voice inserted in.

…!!…

Zhan Zhao and Bai Yutang were not timid people, but in the dark middle of the night, the gloomy archives, the nerves of both of them were in a high degree of tension. A cold voice still shocked the two of them.

A beam of strong light from a flashlight came directly, and Bai Yutang had already seen clearly that it was the old archivist Sun, who was in charge of the information.

"Tao Sun, why don't you sleep so late?" He quickly reached out to protect himself and Zhan Zhao's eyes behind him, "While turning on the light, why are you still using a flashlight to shine? It's not a horror movie."

Old man Sun smiled and turned off the flashlight: "It's you two guys. You guys came to the information room in the middle of the night. I thought some of the blind man came here to steal things."

Zhan Zhao pointed to the gap on the archive shelf: "Tao Sun, do you say that what you are here is a secret archive?"

Old man Sun waved to the two of them and signaled them to follow him.

Following Old Man Sun to his duty room at the end of the corridor, instant noodles were being cooked in the induction cooker.

"It smells so good." Zhan Zhao and Bai Yutang shouted in unison, and then they remembered that the two of them had been busy all night and had not eaten yet.

Old Man Sun took out two more packs of noodles from the cabinet and put them in the pot: "Sit down."

The two sat down with some embarrassment.

"The missing files are all in the same case, and some of them have been sealed as secrets." Old man Sun took out three clean bowls and put some chopped green onions in it. "There are some that have been destroyed."

"Destroy?" Bai Yutang and Zhan Zhao asked at the same time, "How could they be destroyed?"

Old Man Sun put the noodles out and sighed: "It was ruined by that person."

"Who?" He took the noodles handed over by Old Man Sun, it smelled so good!!

"Speaking of this, if that person didn't destroy those files, he might never be arrested." Old man Sun also sat down and said while eating noodles.

"Is it the murderer who destroyed the file?" Zhan Zhao asked in surprise.

Nodded: "It's not just the murderer, but also a policeman."

"Ahem..." Bai Yutang said with a mouthful of pain and didn't choke. Zhan Zhao handed over the tissue, "Do you think he is a policeman?"

"What is the coolest policeman in the bureau back then called the 'Black and White Double Evil'? Have you heard of it?

Bai Yutang smiled: "Sun Tou, are you talking about Baoju and my old man?"

Old Man Sun also smiled: "Yes, it sounds disgusting now, but back then, it was so powerful!"

After eating the last bite of noodles in a hurry, Bai Yutang wiped his mouth and asked, "Tao Sun, what does that murderer have to do with these two old men?"

"Oh..." Old Man Sun sighed, "Except for a few old men, all the young people nowadays don't know. There were actually three people in the black and white evil spirits back then!"

"Three people?" Zhan Zhao was surprised, "Why could that third person be the murderer?"

Sun Tou did not answer, but stared at Zhan Zhao for a while: "He is the same as you."

…?…

Zhan Zhao and Bai Yutang looked at each other, with a confused look on their faces.

Old man Sun put away the bowls and chopsticks on the table: "Psychological analysis... is simply a genius, but he didn't have such a name at that time, and he was still a policeman."

Bai Yutang was a little anxious: "Tao Sun, you have been talking for a long time. Who is that person?"

"...I just said that this is a secret file." Sun Tou smiled, "I have the obligation to keep it confidential. There are only so many things I can tell you, and I really don't know the details. There should be only three insiders."

"Three?" Bai Yutang was puzzled, "Who else besides my dad and the Baoju?"

"He himself." Sun Tou stood up and cleaned up the table.

"He is still alive?" Zhan Zhao was shocked.

Bai Yutang also looked unbelievable: "He killed hundreds of people and was not sentenced to death?"

Sun Tou shook his head: "He can no longer harm others." After saying that, he kept silent.

That night, Zhan Zhao and Bai Yutang were soft and hard to make a splash, and Sun Tou didn't speak anymore, but instead cooked two more bowls of noodles for them.

After coming out of the duty room with a burp, Bai Yutang frowned: "It's mysterious, I'm so unhappy!"

"What should I do next?" Zhan Zhao asked, "Go back and ask your dad?"

Bai Yutang said with you to spare me: "My God! It's been more than 20 years, so it's time to say it long ago!"

"Why ask the baggage office?"

"you go!"

Zhan Zhao was embarrassed: "Can you prove that the two cases are related?"

Bai Yutang shrugged: "He will definitely ask this!"

"Will your mom know?"

"The old man definitely won't let her say it," Bai Yutang frowned: "Otherwise, try getting him drunk... But you will definitely be slaughtered after waking up."

The two walked to the door of S.C.I with a frown, and Zhan Zhao suddenly asked, "Xiaobai, how old is your brother older than you?"

Bai Yutang blurted out without thinking: "Eight years old...ah~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"

Seeing that he had reacted, Zhan Zhao hurriedly said, "Your brother was already in his teens at that time, so he should remember it, right?"

"No, Maoer! I'm not the 'ah' that!" Bai Yutang opened his face bitterly, with an expression of doomsday.

"Then which one are you?"

"...My brother is back today, and I agreed to pick him up."

"Ah?!" Zhan Zhao also jumped, "When is your brother's plane?"

"12 o'clock." Bai Yutang scratched his head.

Zhan Zhao looked at the watch and it was exactly 12 o'clock: "Go quickly! It should be okay if you are late for an hour and a half, right?"

Bai Yutang cried and said, "...it's 12 noon..."

Zhan Zhao opened his mouth and stayed silent for a while, then raised his hand to pat his shoulder: "New record! Judging from your brother's personality..." He paused for a moment and summed up pity, "You are dead!"

Bai Yutang walked around in place for a few times, pulled Zhan Zhao and ran out.
