Chapter 727: On-site Effect

8:00 AM.

Jiang Yuan came to the conference room early, first checked the computer and projector, put a few pages of PPT to test, and then started to ask Qi Changye about the situation at the scene.

Qi Changye was also busy all night yesterday, and now his eye sockets were blue and said: "A few people from our brigade have gone over. I also borrowed ten people. Now there are more than ten people there. By... by 10 o'clock, they can all be in place. Some people had tasks before, and they agreed to go on missions starting today..."

Police work can never be finished. Qi Changye's brigade is a typical high-configuration small team. The levels of units and personnel are relatively high, but the number of people is small, there is a lot of work, and they are always too busy.

Even the people he borrowed have their own work to do. Police work is not like others. It is not said that it will be finished tomorrow, and it will be finished tomorrow. If the criminals don't cooperate, a case can be dragged on endlessly.

Now it is just the beginning stage of the special case. Even if Qi Changye is looking forward to it again, it is impossible to go all out. According to Qi Changye's idea, if Jiang Yuan can maintain the speed of the Zhang Lizhen case and find the remains in a week or two, it is Amitabha—in fact, Qi Changye just thinks so. The Zhang Lizhen case is also equipped with Xu Taining. He doesn't have such an urgent case.

Jiang Yuan couldn't take care of Qi Changye at this time, nodded, and said: "When the meeting starts, I plan to make some on-site effects. I need the police at the scene to cooperate a lot. It is estimated that they will run some roads. By the way, are the police dogs here?"

"The police dogs have set off, and they will be in place in another hour." Qi Changye can shake people, but he also has to pay attention to the basic law. When there is no special situation, it is impossible to let police officers from other units work overtime, or work early in the morning.

Jiang Yuan nodded and continued to look at the PPT.

Qi Changye saw Jiang Yuan so serious, and a suspicion naturally rose in his heart.

His occupational disease made him quickly trace the previous conversation between the two, and then quickly realized a point, and hurriedly asked: "Team Leader Jiang, you just said on-site effect, what kind of on-site effect?"

Jiang Yuan looked at Qi Changye a little unexpectedly, then looked at the empty conference room, and said: "I am considering that the botanists who came this time are relatively outstanding. If we only discuss botany, the effect might not be very good. I want to find a few burial points on the spot, dig on the spot, and try to see if we can find the body on the spot."

"Ah?"

Qi Changye really couldn't help it. Isn't this playing?

The problem is, can you still play like this?

This is a body!

If you can find a body casually, wouldn't I have been beaten for nothing these years? Wouldn't those nights of drinking and singing be like weak young people, "forcing sorrow for new words" to deceive little girls?

If you can really find a body like this, wouldn't the technology of forensic botany explode?

Wouldn't the people's police in various countries and provinces all want to set up forensic botany?

Don't say it's difficult. If you learn it, you won't get a white shirt. You must know that there is nothing difficult in the world, only fear of establishment!

Therefore, from another angle, the on-site effect Jiang Yuan said is too ridiculous. If it was really discovered like this... but, the smart Qi Changye thought about it, this is what Jiang Yuan said!

"Can you really find a body on the spot? Do you already know where the body is? Or..." Qi Changye thought, Jiang Yuan should not think that he would help him bury the body.

Of course, if it is for the spy case, if it can really be solved, think of a way to apply to the above, or just carry it by yourself, it is not completely impossible to consider this problem.

But today's occasion seems to have not reached this height...

"I did some homework yesterday." Jiang Yuan knew that Qi Changye had questions, and explained in detail: "First of all, we can find the body, not necessarily the body you want, and it is possible that what we find is not a human body!"

Qi Changye nodded, and his inner technical points were also updated. In fact, if Jiang Yuan only asked him to bury an animal body, they could still do this level of cheating, and they were relatively good at it...

Jiang Yuan continued to explain: "The basis for our search for bodies is actually mainly the video data searched and taken by drones when Xu Taining Xu Chu was screening a while ago. I have already looked at the plots I marked yesterday, and I have marked the points with questions first, and done a certain amount of research."

Jiang Yuan: "Although it is a bit of cheating, when the meeting starts, I basically just do a case demonstration. More is the cooperation of the scene. The better the cooperation of the scene, the more times we can do case demonstrations. En... the probability of digging out a body at one time is not very high."

Jiang Yuan: "Qi Chu, trouble you to coordinate and cooperate here."

"No problem, no problem." Qi Changye understood, and worried: "If you look for it several times and can't find the body, or only find the animal body, what should you do?"

"It just doesn't achieve the shocking effect. It doesn't affect the work."

"That's true." Qi Changye paused and said: "Team Leader Jiang is quite attentive to these botanists."

"The workload of forensic botany is very large." Jiang Yuan sighed.

He still has needs for botanists. Using forensic botany to solve cases sounds simple, but just finding spores and pollen under a microscope can blind people. But wanting botanists to accompany him to solve cases, without Qi Changye's face, relying on Jiang Yuan himself, is still difficult.

It's like the botanists in Baijiang Province, who also gathered together because of Captain Pang Jidong's face.

Otherwise, these scholars who are over 40 or 50 years old, either famous school professors or full researchers of the institute, how can they spend a few days or even longer to accompany Jiang Yuan to do things.

Not to mention that everyone has their own career planning, their own academic goals, their own work schedule, and Jiang Yuan's level and age are very difficult to unite such a group of people.

As for relying on technology and academic ability, last time, Jiang Yuan used image enhancement technology and LV4 forensic botany to fix it, but this time facing more scholars, and they are all from the capital, it is difficult to say what moths will come out.

If the content of the discussion deviates from forensic botany and involves pure botany—Jiang Yuan can certainly avoid talking about it, but the effect of uniting people is definitely worse.

Considering comprehensively, Jiang Yuan decided to combine online and offline. His advantage is not just the technology of forensic botany.

8:40 AM.

People came to the conference room one after another.

Jiang Yuan only looked up, then changed the PPT, adjusted the software, and occasionally looked at WeChat on his mobile phone to determine the situation of the personnel in various parts.

Qi Changye also typed wildly in the group and called wildly offline.

Online and offline linkage, the most important thing is the human factor, followed by ensuring the real-time situation of various software.

Not to mention the latter, the former is also always changing.

It's like before today, Jiang Yuan didn't know how many people Qi Changye could find. Qi Changye himself was not very sure, so he could only make adjustments based on the situation at the scene.

If you think everyone will cooperate with you, it is really too naive.

Even if Jiang Yuan is a star-level detective now, it won't work. A group of men in their 30s and 40s, soaking in the wilderness early in the morning, might take off their clothes for the stars, but they are not necessarily willing to move their butts twice for the stars.

After contacting each small team once, and finally confirming it once, the 9 o'clock alarm clock rang.

Jiang Yuan "pressed" the alarm clock casually, looked up, twisted the microphone, and said: "Then let's start."

Below, fifty seats were all full.

In addition to the more than 20 botanists invited by Qi Changye, Captain Pang Jidong and the four botanists he brought from Baijiang Province, there were also a bunch of students and more than a dozen police officers at all levels.

Jiang Yuan looked over, and saw that the faces of the police officers were full of expectations, while among the botanists... only Su Lei and Qiao Shengli had encouraging expressions.

Jiang Yuan smiled, opened the PPT, and said: "First of all, thank you all for participating in our case in your busy schedule. Criminal cases have their particularity. There are some regulations below, please read them yourself."

After releasing the page of explanation, Jiang Yuan paused for half a minute, and then said: "Today's introduction, I mainly talk about two parts. One part is the practice of forensic botany, mainly talking about how we use forensic botany to serve criminal cases. The second part is to try to do some real practical work with the help of some criminal police colleagues."

Following Jiang Yuan's words, the botanists only thought it was a simple description, but the police officers present were already excited.

The police officers naturally had a deep impression of Jiang Yuan. Hearing him mention real practical work, they immediately had a real understanding of reality, unlike the botanists present, who only thought that reality was a description of degree.

Jiang Yuan drew another page of PPT and said: "First, let's look at this video. This is the K67 plot. You can scan the map to see the labeling method and range. Let's talk about this plot first... En, in fact, I have already watched this video last night. When I watched it, I thought there was a problem here..."

Jiang Yuan zoomed in on the image, focusing on a patch of grass.

The botanists present sat up straight, looking up to study it, while some, like the students who came with them, began taking photos for their records.

"These are birch, elm, and also Chinese pine and ferns..."

"It's indeed problematic for them to grow like this in a wild environment."

"Looking at the tree age, they're only a few years old, no more than 10 years. This area is definitely problematic."

Jiang Yuan waited for half a minute, then continued: "In forensic botany, this is a relatively typical situation we call a 'seed bank.' Let me explain for the non-professionals present. A seed bank refers to the underground soil containing all the seeds of nearby plants. While the plants on the surface have originally become stable after a long period of competition, once the soil in an area is disturbed, the newly germinated plants will create a new ecology and new competition."

"So this area was disturbed a few years ago? Someone dug up the ground to bury a corpse? In the middle of nowhere, someone digging up several square meters of land is indeed not very normal." A scholar sitting in the front immediately followed up.

Holding a meeting with scholars has this issue: scholars who reach this level are extremely confident. In a small meeting like this, once they encounter a problem or discussion, it will proceed far beyond the intended scale.

"Don't some animals have the habit of digging up the ground?" a young student asked in a low voice.

"If it were just digging, the surrounding plants would immediately invade; they wouldn't give the seeds in the seed bank a chance to grow." Without needing Jiang Yuan, a scholar explained on the spot: "Only in a situation like a corpse, where the corrosive liquid produced by decomposition prevents the invasion of surrounding plants, do the new seeds have a chance to germinate."

"In other words, there must be a corpse under this kind of plot?" The student was surprised: "Is it that easy to find?"

"It's not exactly easy to find, because we started searching from a large-scale map." Jiang Yuan said, continuously zooming out the enlarged map.

As the detailed plot turned back into the appearance of a normal map, the young people present all calmed down.

Give you a national map and find the places where corpses were secretly buried—this was probably what forensic botany looked like in their eyes.

"While the police officers are checking this area, let's discuss another plot, and then we can merge the discussion on the specific corpse-searching process." Jiang Yuan provided only solid information, because he would need these botanists to help with the search later.

And for the botanists, today's scene began to become exciting.

The botanists also began to understand the true meaning, and asked one after another:

"Are we digging for corpses on-site?"

"What do we do if we find one?"

"Can it be found? If we dig one up, is it a murder case?"

Some people even started sharing it with others impatiently; the botanists' group chats and social media were unprecedentedly lively and eye-catching.
