Stay away from Conan.

As research into Ai Haibara's antidote progresses, its effects can now last reliably for more than two days, which isn't necessarily a good or bad thing.

After all, many times when Ai and Conan need the antidote, it takes too long for them to return to their original forms, which can easily cause problems. Therefore, Ai has developed this type of drug to address this issue.

The reason for giving this medicine to Shinichi Kudo now is that, given the current situation, continuing to maintain Shinichi Kudo's appearance would be counterproductive and complicate matters.

After all, allowing Shinichi Kudo to temporarily hide under the protection of the FBI was a compromise under the circumstances at the time. However, if Shinichi Kudo continued to stay here under this identity, not only might the news that Shinichi Kudo was still alive be further exposed, but it might also lead the FBI to discover the secret that Shinichi Kudo was Conan.

While intelligence about the organization can be shared with the FBI, it's unacceptable for Gao Yuan to be concerned about the FBI's intentions, especially regarding drugs that could reverse aging, once that information is leaked.

Therefore, this risk is not to be taken under any circumstances, so it would be better for Shinichi Kudo to "leave" as soon as possible.

Therefore, after Gao Yuan gave the antidote to Shinichi Kudo, Shinichi Kudo immediately realized Gao Yuan's meaning. So he didn't say anything, hid the medicine in his hand, and was thinking about when it would be convenient for him to take the medicine and return to Conan's appearance.

However, compared to that, the immediate problem that needs to be solved is the matter of Hondo Eisuke. He had just recently obtained some clues about Hondo Eisuke from Hattori Heiji, so when all of this came together here, Kudo Shinichi knew that the connection between this person and Mizunashi Rena was not simple. Obviously, Takato knew about the connection, otherwise he would not have taken such a risk to bring Hondo Eisuke himself to the FBI.

Just as Shinichi Kudo was about to continue asking questions, the door to the ward was opened, and the man wearing a black knitted hat, Shuichi Akai, returned with Eisuke Hondo. It seemed that he had already done something with Eisuke Hondo, and Eisuke Hondo was staring at Takato, as if he wanted to say something, but because Shuichi Akai was beside him, he only glanced at Shuichi Akai and then lowered his head without saying a word.

In response, Shuichi Akai closed the hospital room door and went straight to the point, speaking directly to Takato:
"I started to get a little curious. When I took this kid for a checkup, the doctor noticed that he had surgical marks on his body, and not just ordinary surgical marks, but marks left by a bone marrow aspiration..."

"So, although the matching results haven't come out yet, based on this alone, I can be sure you're not just guessing!"

Since Hondo Eisuke has mentioned his blood type and also knows Mizunashi Rena's blood type, it is highly unlikely that the two are siblings based solely on their blood types.

However, now that it has come to light that Hondo Eisuke may have undergone a bone marrow aspiration, almost instantly, upon hearing this for the first time, Kudo Shinichi immediately connected it to something—

To be able to perform this kind of surgery, one must have undergone a bone marrow transplant, in other words...

Since the body's hematopoietic system is surgically replaced with a transplanted hematopoietic system from another person, it is possible for the blood type flowing in the body to change.

Therefore, relying on blood type to determine whether there is a kinship is no longer accurate, or even comparing blood DNA cannot confirm the blood relationship between the two.

Regarding this point, Shinichi Kudo had previously heard Eisuke Hondo mention the blood type incompatibility when he was at the Metropolitan Police Department, which subconsciously led him to deny that he and Rena Mizunashi were siblings, and thus he considered many other possibilities.

But now, Shinichi Kudo knows—

It's possible that the truth is much simpler than one might imagine, but no one expected that Hondou Eisuke had contracted that disease and undergone that kind of surgery when he was very young...

In response, Shinichi Kudo turned to look at Takato because of Shuichi Akai's words. After all, judging from Shuichi Akai's words, it was clear that Takato had said something that made Shuichi Akai take Eisuke Hondo to see a doctor and discover that he had undergone surgery. If there was no explanation, why would Takato give such advice?

Seeing this, Gao Yuan, who was being stared at by several people in the ward, casually said:
"The comparison results aren't out yet, so everything is just speculation and may not be accurate." Thus, Gao Yuan's excuse that everything he gave was just his own guess, rather than any concrete information he had, left those present wondering whether it was just an excuse or the truth.

"Time is precious, so it's best to speak your mind directly. You should also be aware of the current situation."

Shuichi Akai bluntly stated that the organization's threat was likely imminent.

"That's true."

Seeing Akai Shuichi say this, Takato also turned to Hondo Eisuke and mentioned:
"Since we've already heard someone sending messages to that email address in this hospital, it's clear that their people have already found this place."

Takato spoke frankly about Kusuda Rikudo's matter.

Upon hearing this, Shinichi Kudo and Shuichi Akai naturally knew what Takato meant by "email address," so they both hurriedly asked him about it. Takato then recounted the series of keypad clicks that he and Eisuke Hondo had heard in the hospital bathroom.

Then, Shuichi Akai pressed further:
"Who is that person?"

"I remember what that person looked like, but I don't know who they are. Anyway, based solely on that series of keystrokes, two things are clear—"

Gao Yuan then explained:

"Their people have already found this place..."

"And, Hondo Eisuke, you know what this key tone represents, right?"

"This……"

When the topic turned to him, Hondo Eisuke was taken aback for a moment, then, under the simultaneous gazes of Kudo Shinichi and Akai Shuichi, Hondo Eisuke revealed what he knew—

The number corresponding to that key tone should be the email address his father had dialed for his colleague.

"So it seems things are clear now! Just as I expected. But before that, I'd like to ask, could we go see that Mizunashi Rena now?"

Gao Yuan thought for a moment, then said it directly—

Now that things have come to this, it's better to ask the person involved directly than to try to explain it myself... (End of Chapter)
