The other subordinates were also a little stunned. Since those of you here are members of the "Dongda Disappearance Case" special group, they naturally have some knowledge of the more than a dozen "Dongda Disappearance Cases" of the same nature more than 20 years ago. The name Long Kaicheng has repeatedly appeared in the information.

At that time, Long Kaicheng was only in his twenties, and he was already a capable member of the criminal investigation team, with his keen perception and observation ability and outstanding reasoning ability, he cracked several major cases and was known as a new star in the police world.

Long Kaicheng left the police station in the late 90s of the last century, and many people persuaded him to stay, including Meng Cunshan and Lin Qiang, after all, they were just policemen/inspectors who handled cases, and they didn't need to automatically resign from their responsibilities like the people above.

But Long Kaicheng didn't seem to be able to get over the hurdle in his heart, and he left resolutely, and he went for more than ten years without any news.

Unexpectedly, at such a delicate moment, the contact came.

"Hey, Meng Si, you're not thinking about what you're going to do when you step back from your seat, are you?" The voice on the other end of the line laughed.

Meng Cunshan choked a few times: "You old boy is still such a ghost!" ”

That's exactly what he had in mind.

"Your ass should stay in that chair." Said on the other end of the phone.

Meng Cunshan suddenly sat up straight: "Do you have a clue?" ”

"Hey, hey. Don't you know when you come to Dongda? Ah, bring some powerful pumps! And excavators, prepare a couple of excavators! ”

After saying that, the phone hung up.

Meng Cunshan was a little inexplicable, Lin Qiang who was sitting next to him was also inexplicable, Long Kaicheng's voice was very loud, and he could hear it clearly.

"Pumps? Excavator? Do? ”

Meng Cunshan shook his head: "But Kaicheng has always had a lot of ghost ideas, anyway, we don't have a clue now, so let's try it first as he said." ”

Meng Cunshan immediately assigned the task, and he and Lin Qiang first went to the famous lake of Dongsheng University to wait for Long Kaicheng.

"We want to wait on the shore of the famous lake...... Kaicheng wants to pump water from the famous lake? Lin Qiang looked at the lake and said.

"Almost." Meng Cunshan smoked again.

"But...... Didn't we do the same more than 20 years ago? At that time, when the lake was still a few ponds, I didn't find anything. What are you thinking about Kaicheng? ”

"I don't know. As I said, we are now dead horses as live horse doctors, as long as there is hope, we must try. Moreover, Kaicheng had not been heard from for more than ten years, and suddenly called me, and I did not believe that he did not even have any conclusive evidence, so he asserted that the missing people were under this famous lake. ”

Lin Qiang thought about it carefully, and didn't question it too much.

"Anyway, why did Kaicheng suddenly care about this? Didn't he leave the police? ”

"Maybe Kaicheng never gave up. This old boy has been a tendon since he was in the police academy, and he is stubborn. Meng Cunshan said, "In addition to the case, he still has the case in his mind." To be honest, when it comes to climbing up, I definitely climb faster than him, but when it comes to handling cases, I really can't compare to him, from the beginning. ”

Meng Cunshan spat out the smoke ring, saw a figure in the smoke ring, and waved at them.

The man was wearing the uniform of the Dongsheng University guard, but he looked like Long Kaicheng, his facial features had not changed, but he was old, and there were wrinkles at the corners of his eyes and forehead.

The brothers haven't seen each other for a long time, and they hugged them fiercely for a long time.

"You old boy, you are a good policeman/inspector, what kind of guard did you come to Dongsheng University to be! You come to me, with your qualifications and ability, it is not a matter of minutes to restore the police position! ”

"Hey, hey." Long Kaicheng grinned, "When this case is closed, I will naturally come to you for official reinstatement." ”

Meng Cunshan was stunned: "Be honest with you...... You worked as a security guard at Dongsheng University, did you do it because of the disappearance case more than 20 years ago? ”

"yes, otherwise what am I doing in school? Alas, I'm ashamed to say that I've been a university guard for more than ten years, except for catching a few thieves and catching a few sneaky fishers, I can't find any clues about the disappearance. ”

Long Kaicheng took off the guard hat on his head and scratched his flattened hair, which had turned gray from the dark hair in the past. Meng Cunshan and Lin Qiang are about the same age as Long Kaicheng, and their hair is not gray at all at this moment.

Meng Cunshan was a little sad: "Be open, you ...... hair"

"Oh, this. There's no way, I guess I'm thinking too much about the case. Long Kaicheng scratched his gray hair.

"Married?" Lin Qiang asked.

"How can you still have the leisure to get married, the case is not closed. Not to mention marriage, if this case is not settled, I won't even see you. Long Kaicheng put the guard hat back on, "Oh, let's talk about family things, move back, move back." Meng Si, quickly call your pumping brigade to pump water, I want to see what's at the bottom of the lake. ”

Lin Qiang took Meng Cunshan's order to go down to command people, Meng Cunshan and Long Kaicheng stood on the stone ladder by the lake, and Meng Cunshan said Lin Qiang's question just now.

"It was smoked more than 20 years ago, but I think we overlooked something. For example, the silt at the bottom of a lake. Long said honestly.

"But I dug it more than 20 years ago." Meng Cunshan said.

"Not enough. Dig not deep enough. ”

"Not deep enough? We dug every pond to the end. ”

"That's an illusion." Long said honestly.

"Huh?" Meng Cunshan was a little inexplicable.

"I mean, we didn't dig to the end. We think we've dug to the bottom of the pond, and it's a false memory that someone has deliberately created in our heads. ”

Meng Cunshan looked at Long Kaicheng with an inexplicable expression.

Long Kaicheng took out a small plastic bag from his bag and showed Meng Cunshan the powder inside.

"Have you ever seen this powder?"

Meng Cunshan looked at it carefully: "I can't make a conclusion, I have to analyze the ingredients." ”

"There's some hallucinogenic stuff in that. However, I know that it has a more powerful effect, and in some ways, it can falsify human memories, and all those who inhale this powder will be infused with deliberately created false memories. ”

Long Kaicheng ran a little far away from the topic, and Meng Cunshan chased for a long time and didn't catch up, but the person who can sit in the position of the director of the Dongsheng City Police/Procuratorate Bureau naturally has his advantages, such as Meng Cunshan is strong analytical and receptive.

He pinched the powder: "Some of the techniques you mentioned refer to ......"

"I have a hunch that when we dig to the bottom of the lake to a certain extent, you will see it with your own eyes."

Long Kaicheng winked at Meng Cunshan slyly.

Just as Lin Qiang came over, Long Kaicheng took out a box of Huoxiang Zhengqi liquid from his bag, which contained five small bottles.

"Don't drink it now, I'll remind you when it's time." Long Kaicheng took out a bottle by himself and handed the box to Meng Cunshan, "You and Qiangzi each have one bottle, and there are two bottles left, you can see which two brothers you want, you must be strong in combat." ”

Meng Cunshan looked at the small bottle, it was clearly not the packaging of Huoxiang Zhengqi liquid, and the liquid inside was actually purple, and the bottom of the bottle was written with the word "Sakurasaki" in Nihong language.

"What is this?"

"I can't say exactly what it is, but the person who gave me this thing said that it can make the dust ......," Long Kaicheng pointed to the powder in the small plastic bag, "Six to eighty percent of it is neutralized." ”

When Zhuang Yi, Fang Youning, Sun Zhongzi and others came back from class, they happened to see several large pumps pumping water strongly, and the water was about to be drained.

"Is this for us fishing?" Fang Youning's eyes lit up.

The second cargo Sun Zhongzi is also preparing to go back to the dormitory to find a fishing rod.

Zhuang Yi didn't make a fool of himself with the two, and looked at the excavator by the lake: the police really aimed at Shengming Lake.

Zhuang Yi naturally knew that it must be the reason why the dragon guard found the powder, and he couldn't tell if the dragon guard was awakened, but judging from the way the dragon guard looked at the powder, at least the dragon guard knew what the powder was for.

On the stone staircase by the lake, Guard Long was chatting and laughing with the director of the Dongsheng City Police/Prosecutor's Bureau, and it seemed that the two were still old acquaintances.

The origin of the dragon guard is really unusual. Zhuang Yi said in his heart. I didn't go upstairs anymore, and stood by with the other onlookers.

The water was finally drained, and no corpses were seen, so Lin Qiang gave an order, and several excavators were in place.

Long Kaicheng and Meng Cunshan also stopped talking and laughing, and looked at the bottom of the lake intently
