Maggot.

This character can be said to be an outstanding representative of the characteristics of pictographs.

Next to the ideographic word "worm" and the word "and" in the table, together, people can think of a wriggling, long-standing worm in their minds just by seeing the word.

Mao Lilan may not be able to associate maggots with Chinese characters, but she now stands next to a disemboweled, corpse, sniffing the pungent smell of charred tissue and internal organs

In such a foul and foul-smelling environment, the senses of sight, smell and imagination produce a wonderful synaesthesia response.

Therefore, she can imagine the terrifying picture more immersively.

"Maggots, maggots"

"Man's anus"

As a cute beautiful girl, she is still a little embarrassed to say such indecent words directly:

"That place, it's difficult, will maggots still grow?!"

When she said this, Miss Maori turned pale and spoke incoherently.

She only felt a chill near her tail bone, and invisibly, it seemed as if there were really small insects burrowing around.

"Of course the living won't!"

Lin Xinyi shook his head a little amusedly.

Mao Lilan was a little relieved, and heard Lin Xinyi give a popular science that made people's scalps tingle:

"If a living person wants to grow, it will only grow roundworms, nematodes, hookworms, tapeworms, liver flukes, etc., and there will be no maggots."

"Speaking of which, human parasites are also one of the focuses of forensic research."

"Distinguishing the geographical distribution and population distribution characteristics of human parasitic infections can help portray the living environment, space, occupation, medical experience and so on of the victims."

"Since you're going to be a forensic doctor, you might run into parasite corpses in the future."

"Don't be afraid - it's definitely good for us to find bugs in corpses."

Maoriland: ""

Lin Xinyi once again successfully tested the limit of her psychological endurance.

For girls, bugs are probably more difficult to accept than corpses.

And Lin Xinyi didn't notice the student's disgust now, but continued to explain devotedly:

"Of course, necrophiles are more helpful to our forensics than parasites."

"It is difficult to accurately determine the time of death of corpses in the late post-postmortem period, and insects are the biggest help in helping us guess the time of death."

"For example, the most common flies and maggots—"

"According to research, in recent days, during the summer when the weather is hotter, flies that are keen on 'food' can reach the carcass in about 10 minutes."

"Eggs are laid in about 1 hour, and in 10~20 hours, maggots appear on the corpse."

"If the temperature is higher than 30 degrees Celsius recently, the incubation time can be shortened to 8~14 hours."

"Since then, the fly maggots grow an average of 02~03 cm per day, mature in 4~5 days, and have a body length of about 12 cm."

"Therefore, as long as we can find the maggots from the corpse and measure the length of the maggots, we can guess the time of death of the corpse through the growth of maggots!"

Lin Xinyi explained the basic knowledge of using forensic entomology to predict the time of death.

Saying that, he also asked Mao Lilan specifically:

"In the summer in the countryside of Gunma Prefecture, there should be more flies, right?"

"Hmm." Maolilan nodded.

Lin Xinyi, a "spiritual foreigner" in the true sense, is not familiar with the geographical environment of Yuben.

But as a native of Tokyo, Moriran is still familiar with Gunma Prefecture, which is barely counted within the Tokyo urban agglomeration:

Gunma Prefecture is a mountainous area, and the famous Mt. Akina is located there.

The mountains are high and densely forested, and the Pacific climate is affected by the rainy and thunderous summer rains and abundant water vapor, so there is naturally no shortage of flies in the rural areas.

"It's a rural dialect in Gunma Prefecture, and there will definitely be a lot of flies in this weather."

Mao Lilan answered Lin Xinyi's question like this, and then, she asked with some hesitation:

"But, Mr. Lin Xinyi"

"Even if the flies do lay eggs on the corpse, and maggots grow on the corpse, after this level of high temperature roasting, the maggots will probably be burned to ashes, right?"

As he spoke, Mao Lilan couldn't help but glance at the charred corpse:

With such a thick layer of soft tissue almost burned into charcoal, can maggots survive?

"That's really what worries me the most."

"But the good news is that we still have a glimmer of hope."

Lin Xinyi was not hindered by difficulties, and always maintained a positive and optimistic spirit:

"Because flies are 'pervasive' in the true sense of the word."

"In order for the larvae to eat food easily, they bypass the hard-to-chew skin and lay their eggs in various holes in the human body."

"Eyes, nostrils, mouth, ear canal, anus, and forehead"

"And that place, you know."

Realizing that he was lecturing to female students, Lin Xinyi was suddenly a little embarrassed:

"In short, wherever there is a hole, they will drill."

"And this corpse is seriously damaged by high temperature, and the eyes, nostrils, mouth, and ear canals, which are close to the surface of the body, have been burned and charred by the high temperature, and I am afraid it will be difficult to find maggots that can be preserved intact."

"However, the anus and rectum are not the same."

"The meat layer there is thick and insulating, like a mud seal on the outside of a chicken."

"Even if the outer layer of mud is burned hard and blackened, the meat inside is still tender."

Lin Xinyi unconsciously said the metaphor of making Maolilan sour water gush, and gave a conclusion with great devotion:

"So, as long as there are maggots in the anus of the deceased."

"The bugs will only be scalded to death by the heat that seeps into the outer layer, and will not be burned to indistinguishable charred ash like the skin on the surface of the body."

"I see."

Without Lin Xinyi's explanation, Mao Lilan can imagine what Lin Xinyi will do next.

"I'm going to get a gas mask now!"

She was like hearing that Zhang Liao was coming to Sun 100,000, and when she turned around, she ran away in fear and with a pale face.

Soon, Moriran ran to the equipment room and took out the gas mask.

Lin Xinyi also changed his mask and put on a gas mask-

Although he can actually tolerate the smell, since he has a use, he naturally has to use it.

And these ten percent new good things have been kept in the Metropolitan Police Department to eat ashes, and it is a waste not to use them.

Change your equipment and start the operation:

"To remove the rectum, you first have to separate the retropubic extraperitoneal soft tissue."

While explaining to Mao Lilan, Lin Xinyi cut the peritoneum around the bladder and separated the bladder, prostate and the back of the urethra.

The soft tissue behind the rectum is then separated, and the rectum, bladder, and prostate are removed about 2 cm above the anorectal commissure.

When these organs are taken, the picture is indescribable, and the smell is extremely unpleasant.

Even with a gas mask, Maoliran felt a pungent smell constantly drilling into his nose.

But the next operation, the taste is even more pungent.

I saw Lin Xinyi put the isolated rectum on the pathology collection table, and carefully cut the posterior wall of the rectum along the midline to expose the intestinal contents inside.

The rectum is a road, and the smell after opening it can be imagined.

In the face of this suffocating Ba Wang's seizing qi, ordinary people are afraid that they would have fainted a long time ago.

But Lin Xinyi looked indifferent and was still busy.

He asked Maolilan to help him hold up the magnifying glass, and with a pair of tweezers in each hand, he searched and searched the mucous membranes of the intestinal wall and those indescribable substances very carefully.

Just seeing this picture, Maolilan couldn't hold it anymore.

But seeing Lin Xinyi's focused, dedicated, and resolute demeanor, she unconsciously forgot about nausea and nausea, and worked hard to help Lin Xinyi stabilize the magnifying glass and persist.

finally

After a difficult period of digging for gold in, Lin Xinyi was pleasantly surprised to turn out something smaller than a grain of rice:

"Found it!"

"This is the larvae of maggots!"

Lin Xinyi's mood was very excited.

If this thing appears in the hot pot base of the restaurant, of course, it will be disgusting.

But if it is found in the corpse, although it is still disgusting, it is definitely good news that can make the investigators happy.

"Sure enough, although the larvae have been scalded to death, there are still 'corpses' left."

"Let's measure the length of 03 centimeters!"

Find the maggots, measure the growth length, and the answer is coming out:

"Counting the incubation time, the time of death of the deceased can be confirmed to be at least about 2 days!"

"In other words, on Thursday evening, when the body was burned and maggots were scalded, the deceased had already been dead for 2 days."

"The real time of death of the deceased, at least on Tuesday night."

"And the time when Yutaka Abe left Tokyo was on Wednesday morning."

"Miss Maori, we succeeded—"

After a lot of hardships, Lin Xinyi finally spoke out for the deceased and let the truth surface:

"Yutaka Abe's carefully designed alibi has completely failed!"
