Chapter 684 Forbidden Spell

Jasmine, bougainvillea, gardenia, hibiscus, lotus...

As Jiang Yuan identified more and more types of pollen, even the criminal police who did not understand forensic botany felt very excited.

Although these are some common plants, there are definitely not many places that fully meet these pollen requirements, and they may even be unique places.

Jiang Yuan didn't have the slightest doubt about this.Although the victim may have traveled to and from multiple locations, the pollen contaminated on his body varies by region and proportion.This is the most critical point of the pollen map.

In addition, sunflower pollen is extremely unfriendly to murderers.

Insect-borne pollen is the favorite type of pollen among forensic botanists, which means that at least hundreds of people around the world like it.

Insect-pollinated pollen is usually very thick because it does not need to be blown away by the wind like wind-pollinated pollen. For bees, insects or hummingbirds, the pollen is thicker and thinner and cannot be felt at all. Weight changes.

But for pollen, thicker walls mean better preservation conditions, and the ability to resist the external environment is completely different.Therefore, the sunflower pollen that Jiang Yuan saw directly grew like a space fortress, and its defense power in the pollen world was about the same level.

This level of sunflower pollen is naturally larger, and it is easier to stick to people's clothes. At the same time, it is easier to identify.

It would be impossible for an ordinary Forensic Botany LV1 player to miss such a large amount of sunflower pollen.

However, for students of botany, the judgment of Asteraceae is really more cruel than cutting the Asteraceae.To confirm that it is sunflower pollen, it is estimated that it will take a lot of effort.

Jiang Yuan didn't stop there.

This time, he searched for a specific taxonomic illustration, classified the sunflower pollen he found into categories, and finally came to the conclusion that the pollen belonged to the edible sunflower: Sukui No. 2.

After reaching this point, Jiang Yuan let go of the microscope, rubbed his neck, wrote a simple appraisal report, and handed it over to Tao Lu.

In fact, it only took more than a day, but for Tao Lu and others, they got more clues in this day than in the previous month.

Most importantly, after the previous "training" to find the source of pollen, everyone has already learned a lot about it.

"Sukui No. 2 is an edible sunflower, which means the sunflower we usually grow? The kind grown by farmers?" Tao Lu read the appraisal report and handed it to Liu Sheng.

Jiang Yuan nodded and said: "Yes, sunflowers are divided into several large types. Common ones are cut-flower sunflowers, which are the sunflowers sold in flower shops. The flower branches are longer, the flowers bloom faster, and some have a longer flowering period. There are also landscape-type sunflowers, potted types, and the edible types we find now, as well as oil-type sunflowers.”

Cui Qishan, who was next to him, felt complicated when he heard it. He rubbed his head and said, "I thought the pollen found this time would be the kind of sunflowers sold in flower shops, which are cut flowers, right? Can it be distinguished? pollen."

"Many varieties of cut-flower sunflowers have no pollen, such as Moulin Rouge and Chianti red wine. Some famous varieties have different pollen colors, such as black oil. You can tell from the name that the pollen in the middle is black. "Many contents of this part of Jiang Yuan are also checked on the spot, because new varieties of plants are emerging one after another, some pollen has changed, some have not changed or have changed very little, and they all need to be compared in real time.

Cui Qishan and others just nodded in confusion, not knowing that Jiang Yuan in front of them had just silently cast a forbidden curse.

Even though the pollen appearance of new varieties of sunflowers is recorded and described, there are no pictures of them.In fact, most of the pollen has only descriptions and no pictures.

If you want to take a picture of pollen, you need to wrap the pollen in gold foil under a scanning electron microscope, and then put it in a vacuum, so that you can take an accurate picture. Therefore, some plants have pictures of pollen, and more are not. No.This is also one of the reasons why pollen research in forensic botany or botany always lags behind. You think that botany is a test of memory, like liberal arts. In fact, botany also requires your spatial imagination, as well as analysis and induction. Possession and ability, pure science.

With the blessing of LV4's Forensic Botany, Jiang Yuan also activated the temporary +1 skill to compare the correct type of sunflower pollen.

Cui Qishan and others looked at the appraisal report and thought that forensic botany was like this.

Jiang Yuan did not need to explain this part in detail. He only said: "Although Sukui No. 2 is an edible sunflower, judging from its pollen map, it includes jasmine, bougainvillea, gardenia, hibiscus, lotus, etc." , are common ornamental plants, and the victim most likely fell to the ground in a garden, courtyard, or park, and was subsequently contaminated with the pollen, and it is unlikely that he was in a pure farmland."

"If we were to find a place with more than a dozen kinds of flowers in the whole city, the area would still be a bit too big." Tao Lu said, lowering his head and thinking about it.

The reason why he said it was within the entire city is because it is very dangerous to leave Beijing or enter Beijing with a dead body. The checkpoints in the middle are much stricter than ordinary toll booths, and there are police dogs in many places to help However, as long as the murderer knows how to weigh the pros and cons, he also knows that going to Beijing to abandon the corpse is purely mentally ill.

In addition, Victim No. [-] himself mainly works as an escort in the capital and has no record of coming and going. After all, he is the type of person who kills people in the capital and throws them away.

But as Tao Lu said, even so, the area of ​​the capital is still too large.

Jiang Yuan said at this time: "I think we can continue to follow the sunflower search. Although Sukui No. 2 is a relatively common edible sunflower, its main planting areas are in the northwest and Inner Mongolia. It is also found in Beijing, and the number is very small. , Therefore, there must not be many people selling and buying Su Kui No. 2 seeds within the capital city..."

In fact, Tao Lu was already excited before he finished speaking.

"We have experience in this area, check the source of the seeds... Well, if you count the online sales records, there will not be much. If it is grown in the garden, it will only buy a very small amount of seeds, or It’s what you want from someone, no matter what kind, there must be a source. Once we find the source, we can ask where the sunflowers were planted.” Tao Lu stood up, feeling that the case had already begun.

Cui Qishan said: "It may also be the seed left by the murderer himself."

"Most people don't have that much time." Tao Lu looked at Cui Qishan and said, "I mean saving seeds is a bit difficult... In this way, let's check up to 5 years ago to see who are the buyers of this sunflower seed. If If we can find the first scene, there will be hope for this case!"

"That's right." Cui Qishan chuckled twice, and then a flash of inspiration occurred. He couldn't help but look at Jiang Yuan and said, "There are also these lotus and other pollen. Can we also identify a specific variety?"

Jiang Yuan smiled back: "Lotus is a perennial root. However, I will look at other flower varieties."

Even if he wanted to check, he would have to refresh the skill cooldown of +1 temporarily before he could continue to check.

At this time, Tao Lu and others could no longer care about this.

While checking the source of the sunflower seeds, they rushed to the scene, one farmer after another, and started to investigate one by one.

Although the total number is already a considerable long list of hundreds of people, for Zhengguang Bureau, this is a normal investigation!
