Liu Yongxin's face was filled with excitement, and he kept wavering to a little detective beside him, signaling him to call someone quickly.

"Call people in the intercom and let everyone from the technical department come over."

The detective nodded in a hurry and repeated what Da Zhao said to the intercom. Everyone ran over for a moment. Liu Yongxin gasped and squatted beside Da Zhao.

"What did you find?"

"Footprints, although the footprints are not complete, the pattern is too special. I think it is the same as what I found in the Xiaoqu flower bed. And looking at this location, this kid's eyes are very good. He said it was a pit from peeing. I found that it really looks like, Uncle Liu, you

Take a look, according to the position left by the footprints, this person should be peeing in the direction of the hillside.”

Old Yang also squatted down, took off his mask, and approached the place and sniffed it carefully.

"It's really peeing. This person is very energetic. There were dead grass here, but they all rushed away."

Liu Yongxin looked at the distribution of footprints and squatted down as he learned to do so. He suddenly realized:

"This man squatted down to pee in order to avoid sound and facilitate hiding, so the dead grass was washed away part of it. His vision was not good at night, so he didn't notice it. As for the footprints, compared with the flower beds in the community, I feel even more, this

People are above 180, otherwise they would not have done so."

"Uncle Liu, then continue searching?"

Liu Yongxin waved his hand and turned around and looked towards Qin Da's direction.

Looking at this position, there was a stone in front of me. This place was a perfect air shelter, which could reduce the spread of the smell. Liu Yongxin suppressed the surprise in his heart and waved his hand at the people around him.

"From here to the location of the stone, we searched ourselves, and saw the broken branches, footprints, even cigarette butts, garbage, all the traces. I think we are close to the position where the murderer was squatting, on that stone

It is the perfect place to observe."

Da Zhao nodded and quickly called Sun Gaoti and the others to come over, hoping to carefully observe everything below with a magnifying glass. Small flags were forked one by one, Fang Mu and the others ran over. Liu Yongxin held the magnifying glass and knelt on one knee.

There are seven footprints that are trampled on the land, and the sense of direction and rubbing are retained. Liu Yongxin analyzed it carefully.

"This person's 44-sized shoes are inferred based on the pace, footprint depth, etc., and the height is between 180 and 185. The outer side of the left heel is seriously worn, and the right foot is bearing the load. Normally, most people have the right foot,

But this person's left foot has a horoscope and one-sided wear on his left foot. I think he can consider that this person is left-handed.

In addition, there are old injuries below the knee joint of the left leg, causing knee valgus. Fast walking will restrict movement and form compensatory steps. It may not be discovered while walking slowly or running, but fast or moving footsteps horizontally are not controlled.

When you are aware of leg damage."

Da Zhao came over with excitement.

"I found a urine sample, and the person's left leg is still a little problem. Isn't this closer to the truth? Let's find out if there are any clues left?"

As he said that, he helped Liu Yongxin up, and the few people walked behind the stone. Yang Xuetong and Wang Henjian had already climbed up. The driver Lao Wang, not far away, picked up an L-shaped cigarette butt with tweezers. The cigarette burned three times.

Two parts, the remaining part of the head is pressed and piled up into a lump.

Look at the location of the stone and then take a closer look at the sign on the cigarette butt.

"Zhao Henjian, look at this cigarette butt. I think someone was standing on a stone, pinching the cigarette butt and extinguishing it, and bounced it away with his fingers. There were tooth marks on it, and maybe you could find fingerprints."

Da Zhao climbed a handful of stones and hurried down to the driver Lao Wang, put the cigarette butt in the physical evidence bag, and handed it to Liu Yongxin. Lao Yang and Wang Henjian on the stone also began to find a place to extinguish the cigarette butts, for a moment

Find three or four charred positions on the left edge.

"I found it. I should have pressed it here and then threw away the cigarette butt. Liu Shuer is not a professional killer. How could he leave such a thing behind?"

Liu Yongxin had already raised the cigarette butt and looked carefully, with a hint of enlightenment on his face.

"It's right for people to be professional, but I think the tobacco he smoked was made of ingredients and looked normal. However, there are pinholes at the bottom of the cigarette butt filter. One is so decisive that it can lurk several times.

People who leave no traces of their childhood can leave such things, either to restrain pain or to have an addiction attack and take the initiative to suck it."

Da Zhao nodded, his little eyes wide open.

"Uncle Liu, so, this person is related to Fang Shengping's case. When we found Zhang Meng, the waiter who was hidden by Liu Liwei, she sucked the cigarette with this kind of feeding, and the injection locations of the brand were the same."

"Not necessarily, put away the things, and look for any other residues. If not, look around the stone to find the way for this person to go down."

Needless to say, the few people moved. Fang Mu shouted everyone and stood on standby for the time being. After all, with such a meticulous survey, professionals are more meticulous and able to have direction. This is the biggest gain.

After a while, after searching, they followed Yang Xuetong and Sun High-speed Railway who were opening the road ahead and found a way down the mountain. This is a ditch-like area on the eastern foot of Fushan. There are few weeds on the ground, all of which are gravel and gravel, and there are not many footprints.

It is the closest place to reach the middle of the two communities.

After arriving at the foot of the mountain, he took photos of the footprints he found again. After collecting the traces, Da Zhao shouted on it, asking everyone to dodge it. He carried the survey box, pressed the timer, ran down from the top quickly, and rushed to two communities.

I took the parking lot with me and took a look at the time. It only took more than ninety seconds.

Gasping, Da Zhao looked at Liu Yongxin.

"Uncle Liu, the time we used to get here is shorter than we guessed. Without carrying a box, I think even with my bag, I would get off for a minute. From here, I went around the south side of the villa, climbed over the guardrail and arrived at the flower bed.

It takes up to three minutes.

Zhou Xiaozhou was not driving fast, so he drove up from the intersection of Qindayi Road, found a parking space, and then returned home. It took ten minutes to start. It seemed that the murderer had already figured out Zhou Xiaozhou's habits and had plenty of time to prepare."

Liu Yongxin nodded.

"It seems that we have found the location of the suspect's ambush. This is not enough. After the injury, he did not appear in surveillance. So should he go up the mountain as usual, avoid the crowd and surveillance from the mountain, and then find the means of transportation to leave?"

Liu Yongxin’s guess was bold, but after hearing this, Zhao Xinli and the others nodded.

"Indeed, I think it is impossible to leave the campus. After Lao He found Zhou Ning, he sent him to the hospital and called Director Xu to notify him. Someone immediately arrived here on duty, and wanted to escape from the scene without knowing it.

Not yet photographed by surveillance.

He only has one path, that is, to return to the lurking point on the same road, then go up the mountain in a reverse direction, and cross Fushan from here to north. If he has good physical strength, he can walk directly to Jinsong 3rd Road. Anyone who finds a place nearby can park the car quickly.

”

Liu Yongxin nodded.

"Tell Xiaoqu what you think, you can find all the surrounding surveillance. Of course, it is not limited to the close-range road. Da Zhao's idea is indeed possible, but don't forget one point, the murderer's foot is not straight, and this person can't wait.

Affected, but climbing a mountain may still be difficult."

Da Zhao was silent, Liu Yongxin patted his shoulder, and it would not hurt everyone's enthusiasm at this time. He quickly exhaled and said:

"The traces left by the arrows on Zhou Ning and their house have been collected, have they collected samples?"

"Well, it has been collected, but the inspection results have not been viewed yet."

"That's good, let's withdraw."

In the laboratory on the fourth floor of the Technology Department.

Peng Shinian kept typing on the computer, Xiao Qu was watching his input and his notebook.

Liu Yongxin and the others entered the room, but neither of them noticed it. When they walked to the side, Peng Shinian suddenly found someone approaching. He was so scared that he shivered. The stack of papers placed next to him fell to the ground.

Liu Yongxin picked it up and took a look. It was all in English, and there was also an icon that was also in English.

"What's the progress of your PSP?"

Xiao Qu came over with a smile, obviously very excited.

"I won't talk about the process anymore. Anyway, it's very cumbersome. However, after several reports, the comparison between the fishery department and the health department, we found that there is a marine biology laboratory in Xinghua, which was once considered the biological laboratory of Qindao Ocean University.

branch office.

In the past year or so, they have collected a large number of Hokkaido scallop samples, and the collection location is the origin of three high-content PSP Hokkaido scallops mentioned in the previous report. These are their purchase volumes, up to 23

ton.

Moreover, 99% of the raw materials they purchased were the glands of the Hokkaido scallops, and only a small amount of the whole Hokkaido scallops were used as samples. According to the equipment reported by their laboratory, the extraction of PSP can be completed.

”

Da Zhao blinked, estimating the weight in his mind.

"23 tons, 23,000 kilograms, a laboratory uses such raw materials. How many trips does it take to pull scallops just? It has to be shelled. It requires processing so much scallop meat. Can a laboratory do it?"

Peng Shinian shook her head, looking excited.

"It sounds like a lot. In fact, the content of scallop meat in 23 tons is less than one-tenth. We estimated it and calculated based on 2300 kilograms. These are not all used for extraction. After all, PSP mainly exists in Hokkaido scallops.

Inside the gland.

The glands account for about 1/12 of the meat, which is 191 kilograms. Generally, the laboratories can extract it, and this procurement is not completed at the same time. After all, this is not artificially cultivated. The collection season is between June and December last year.

.”

Liu Yongxin interrupted Peng Shinian. He knew that Peng Shinian was an academic person. Finding these things was more exciting for him, and what he wanted to know was not this.
