The Grammatical Investigator in Conan

After hearing Qin Zhibo's conditions, Mark Allen took a deep breath, but still chose to compromise.

"That's not called mermaid disease."

"The scientific name of that disease is 'Deep Diver Syndrome'."

Deep Diver Syndrome

Qin Zhibo narrowed his eyes slightly and remembered that among this week's mall props, Deep Diver was mentioned in the introduction of [Deep Diving Potion].

This deep diver is

Qin Zhibo did not immediately raise his question.

He could see from Mark Allen's hesitant expression that he was still struggling with whether he should speak out. There was no need for him to interrupt him at this time, and there was no need to use [Intimidation] in his social skills to scare the old man.

After half a minute of silence, Mark Allen finally began to speak.

"Deep Diver Syndrome refers to the fact that when humans combine with 'Deep Divers', the hybrid offspring born will rapidly grow into 'Innsmouth-looking' at a certain period, and eventually become like 'Deep Divers' Frog looks like.

At the beginning of the change, the eyes of the mixed-race person will gradually bulge, causing the eyelids to be unable to close, the skin will turn gray-green, wet and cold, and the skin on the back of the neck will also become loose.

Next, scales will grow on the body surface, and then the webs required by aquatic animals will grow where the five fingers are connected, and gill structures will grow on the back of the neck.

When the final transformation is complete, these hybrids will enter the water from bays and other watersides and become deep divers forever. "

Allen explained a lot in one breath, and after spitting it out quickly, he immediately picked up the juice on the table and moistened his throat that was dry due to nervousness.

The description of "Deep Diver Syndrome" reminded Qin Zhibo of Keikazu Shimabukuro, who was exactly what Mark Allen said.

However, these explanations did not completely resolve Qin Zhibo's doubts, but instead created more problems.

The first and most important question is.

"What is a Deep One?"

Speaking of the deep diver, Mark Allen leaned back a little behind the chair, placed his hands on the armrests of the plastic chair, and looked extremely solemn.

"."

"The deep divers are a marine humanoid race with fish characteristics. They have intelligence that is not weaker than that of humans, but they spend most of their time submerged under the waves.

They will not die from the effects of aging, nor will they die without external influence, so the race of deep divers has an almost eternal life. "

Immortal?

Qin Zhibo's thoughts changed, and he felt as if he had heard a proposition about immortality somewhere.

It's APTX-4869!

In practical terms, APTX-4869 seems to be able to achieve eternal immortality.

Qin Zhibo currently knows three effects of Drug A.

One, as poison to kill. Second, let a few people rejuvenate. Third, let the injuries on the body heal quickly in the process of getting bigger and smaller.

The first two points were learned through peeking into Hui Yuan Ai's memory, but the third point was discovered by Qin Zhibo himself.

Maybe even Conan and Haibara Ai didn't notice that the gunshot wounds on their bodies healed at an incredible speed.

Of course, this may also be due to Qin Zhibo's own sense of time and his misunderstanding of "soon".

However, APTX-4869's method of achieving immortality is still different from that of the deep divers.

At the Cupido Hotel, Haibara Ai explained the principle of Drug A when she "delivered her last words", saying that its principle is to induce premature aging and apoptosis of cells and promote the proliferation of new cells.

But the eternal immortality of deep divers is that their cells will not age and undergo apoptosis.

But correspondingly, targeted drugs to treat "deep diver syndrome" can make these cells of deep divers undergo apoptosis.

Regardless of what the drug is about, Qin Zhibo now knows the name of the creature he wants to hunt in the main mission.

Deep Diver.

Although he is immortal, he will still die if he is affected by external forces, which shows that it is still possible for him to kill a deep diver.

"What do you mean by 'Innsmouth appearance'?" Qin Zhibo continued to ask.

"Innsmouth is a place name in the United States."

Speaking of a relatively relaxed topic, Mark Allen sat up slightly from the back of his chair, "That place is in Essex County, Massachusetts. There was originally a building called Seal at the mouth of the Manuset River. The town of Smouth.”

"The locals in Innsmouth intermarried and traded with the deep divers, so that the hybrid offspring they gave birth to looked like that, so they were called the 'Innsmouth look'."

"Original?" Qin Zhibo caught the essence of the question.

"Well," Mark Allen swallowed, "In July 1927, this city was reported by tourists. The local government sent a large number of troops to arrest Innsmouth en masse. It was completely reduced to a dead city."

"The existence of deep divers and deep diver syndrome was only discovered at that time."

New clues appeared again. Qin Zhibo silently recorded the name of Innsmouth in his mind, and continued to ask: "Why do the mixed-races take different times to become 'Innsmouth-looking'?"

This discovery naturally came from Shimabukuro Keikazu and Taira Ie. The two people were dozens of years apart in age when they began to transform.

After hearing Qin Zhibo's question, Mark Allen was a little surprised, "You actually know this?"

"Actually, hybrids with Deep Diver Syndrome are no different from ordinary people for a certain period of time after emerging, but at a certain time they will suddenly enter a transformation stage that lasts for 2 to 3 months.

Different people transform at different times, at different speeds, and to different degrees. Some people may even not notice any abnormalities throughout their lives.

This is directly related to the concentration of deep diver blood in hybrids, but it is also affected by environmental factors.

For example, mixed-race people are subjected to extreme psychological pressure, or are in contact with their own race."

Qin Zhibo was stunned for a moment, and his mind unconsciously thought of Shimabukuro Kimie who lived with Shimabukuro Keiwa.

In the previous year, Shimabukuro Keikazu had always had targeted drugs to maintain his human appearance, but now that the targeted drugs have been used up, wouldn't it mean that Shimabukuro Kimie was in contact with his own race?

this.

Just when Qin Zhibo was thinking about the urgency of this matter, Mark Allen couldn't restrain his inner agitation and asked again in a strong tone: "You said it! If I tell you about the deep diver syndrome, you tell my daughter thing."

Qin Zhibo weighed it in his heart and realized that he almost knew what he wanted to know, so he told Mark Allen about his experience on Okinawa.

Hearing how his daughter died at the hands of the housekeeper, Mark Allen was greatly shocked, his face was dull, he held his temples with his hands, and two lines of old tears ran down his saggy face.

"Finally, I would like to ask you a question. Did your daughter inherit the deep diver bloodline from you?"

Mark Allen shook his lowered head from side to side.

"It's her mother."

"Now that Kamiko and Koto are dead, it's all my fault..."

"If I hadn't fallen in love with an experiment"
