Qin Man humbly accepted his teachings, and did not change his teachings, and when he went downstairs, he put his hands in his pockets, his face was sullen, and he was not happy to see anything.

She didn't bend so much to let the fat in front of her fly away.

"Is this corridor so trendy? Why is there still moss growing everywhere...... No one cleaned up ......."

Jiang Lian walked in front, "Then you be careful." ”

He glanced at the ground following Qin Man's words, and sure enough, as she said, wherever there was water, it was faint and green.

He suddenly had a flash of inspiration and stopped on the steps, and Qin Man didn't notice and hit him directly on the back.

"Damn, what are you doing?"

He jerked his head back at the stairwell on the third floor, the puddle of water beneath the row of plants, and in a trance, he realized that something was wrong.

When he came, he felt that something was wrong, and now he seems to understand.

He squatted down nearby, and there was a small piece of dampness at his feet, probably because the owner of those plants did not have good watering habits, and he liked to shake around with the kettle, and a lot of water leaked.

He casually tapped the green in the spot, leaned closer to take a closer look, and rubbed it on his hand, which was slippery and disgusting.

"It doesn't seem like moss."

"Moss is a bryophyte, especially common in damp places, but it can not only grow in water, dark walls, roof tiles are seamless, like hair, climbing and multiplying, tenacious vitality, if it is moss, the water has become green, walls, cracks should also be crawled full."

"But these are only in the water, and they float on the surface, more like some kind of aquatic algae."

Qin Man asked curiously, "Aquatic algae? Is there any difference? ”

Jiang Lian looked around, "There is a big difference, these two things are not easy to distinguish with the human eye, but they are two completely different species. There is a simple and crude way to make a preliminary identification: moss can be found everywhere in damp places, usually in a clinging form, while algae are more common in freshwater and are usually free and floating on the surface of stagnant water. ”

Qin Man felt that this was too.

"How is it possible, even if it is dark and damp here, it will not grow algae, and it is not a ...... in the river"

Qin Man realized something, his eyes widened, he opened his mouth slightly in surprise, and muttered.

"You mean ......"

The two of them collided with each other, and they immediately understood what it meant.

The murderer who hit and killed Du Zhong abandoned the car and jumped into the river to escape!

The executioner, and the murderer who killed Du Zhong, are the same person, and he is still hiding here!

Qin Man almost spoke, Jiang Lian hurriedly covered her mouth, looked upstairs, there were only the two of them in the empty corridor, he quickly grabbed her hand and went downstairs and got into the car.

"Guo Siyan, bring trustworthy people to the recreation community, immediately."

Hung up on this phone, and another one.

"Yang Yuhe sent someone to keep an eye on a unit of the recreation community 24 hours a day, retrieved the surveillance video of the corridor gate in the past five days, and compared it with the road monitoring of the vehicle that caused the accident."

Yang Yuhe on the other side: "Huh? Team Jiang, what do you mean? ”

Jiang Lian: "Do it, and, don't make a noise." ”

Qin Man couldn't sit still at all, and took advantage of Jiang Lian's phone call to push the cause and effect again.

"The god card released the executioner, and it doesn't count if he killed four people in the house, and Du Zhong, the fish that slipped through the net, didn't escape and was wiped out."

"No wonder we haven't been able to find any trace of the executioner, it turns out that he has been in the building all the time and has never come out at all!"

Jiang Lian was not so happy, "The executioner is just a chess piece, and it will be discarded at any time, but if we can find traces of the poisonous dragon from the executioner, we will have one more point in our hands, and the odds of winning will also be one more point." ”

"So what now?"

Jiang Lian was calm to soothe her impatient.

"People can't run, wait, wait for technical reconnaissance to come, and find a way to confirm the final location."

At this time, when the sun set on the West Mountain, on the branches of the moon, Yang Yuhe specially sent the results of the investigation.

"Team Jiang, I found it, it's this person!"

Yang Yuhe opened his laptop and pulled up two video photos after comparison.

"Team Jiang, you are a god, how do you know that this person is hiding here?"

Jiang Lian asked briefly, "Have you found your identity information?" ”

Yang Yuhe was very efficient, nodded, scrolled with the mouse, and called up a file.

"I found out, it's him, Li Qianguang, 36 years old, unemployed, committed the crime of intentional injury five years ago, spent three years in prison, and was released from prison two years ago, it seems that he is mixed up again."

The man in the photo has a round bald head, his eyes are dull, and he doesn't look very smart.

Qin Man commented, "It looks like an addict." ”

Yang Yuhe: "I don't know, it's not written in the case record." ”

Guo Siyan knocked on the car window, and Jiang Lian immediately rolled it down.

"Team Jiang, it's done."

Jiang Lian opened the door and got out of the car and listened to Guo Siyan make a brief introduction.

"We used the most advanced water microalgae chlorophyll fluorescence technology to reproduce the footprints, which are not visible during the day, and now the fluorescence effect is visible when it is dark, although it is not complete and intermittent, but the path can already be seen."

Jiang Lian called Yang Yuhe out of the car, and Qin Man followed.

Without saying anything more, he reached for his waist and handed her his gun.

"Will it work?"

Qin Man didn't answer, "What about you?" ”

Jiang Lian said succinctly, "Am I not with you?" ”

When Qin Man heard this, he took it confidently, and simply loaded the gun.

Jiang Lian ordered, "Arrest the suspect." ”

Guo Siyan was very skeptical, "Team Jiang, you are the three of you...... Don't call for reinforcements anymore? ”

Jiang Lian was full of confidence, "No, it's enough." ”

Guo Siyan is worthy of being a technical talent, and his fluorescence technology is very good, and through the microalgae creatures glowing with light green and dark light, he can vaguely distinguish one incomplete footprint after another.

In the end, the fluorescent footprint finally stopped at the door of room 302, facing the door of room 301.

Rossie appeared unexpectedly that day, also claiming to be the owner of 302, but no matter how she looked for it, she couldn't find the key to open the door.

Jiang Lian gestured to the two people behind him, raised his hand and knocked on the door heavily.

Bang, bang, bang, no one responded.

He whispered, "Stand back a bit." ”

Yang Yuhe and Qin Man retreated according to their words, Jiang Lian raised a foot, the door lock was loosened, and another kick, the lock cylinder was directly scrapped, the hinge trembled, and the door bounced inward and was violently broken.

The three of them rushed in at once, and the room was pitch black, with no sound except for the overwhelming creak of the door hinge.

Yang Yuhe was worried, "With such a big movement, will he jump off the building and escape?" ”

Qin Man squinted his eyes and saw a black thing lying on the sofa, and pointed his gun at it.

Suddenly, the light shone brightly, and Jiang Lian turned on the light in the dark.

Originally, I was worried that the suspect would jump off the building and escape, but when the light came, everyone fell into a deep speechlessness, feeling that they were blind and worried.

Qin Man lowered his hand and couldn't help but roll his eyes.

The suspect in the photo, who didn't look very smart, was lying on the sofa on all fours at the moment, sleeping as if he was dead, and he didn't even wake up to such a big movement as breaking the door.

In front of the sofa, all kinds of finished fast food boxes and drink bottles are piled on the ground, and the coffee table is a mess of ashtrays, half-smoked cigarette cases, mobile phones, remote controls, laptops, half-cans of unfinished beer, and unknown white powder is sprinkled next to it.

Qin Man walked over, reached out and wiped a little of the white powder, and sniffed it lightly on the tip of his nose.

She rubbed her hands clean and said dismissively.

"It's a big pump......"

Jiang Lian was not very interested in this person, and his eyes were always on the laptop.

"Team Jiang, there seems to be something under the computer."

Jiang Lian gently moved the fuselage, and it was a black SD card that was only the size of his little finger.
