Temporary antidote for APTX-4869.

This is one of Haihara Ai's trump cards against Conan, and he didn't want to use it at first.

In order to experiment with the effect of the antidote, Conan was given a dose of the antidote. As a result, it resulted in the death of someone (the life of a passer-by), and it was almost exposed that Kudo Shinichi was still alive.

If she hadn't predicted that the grown-up Conan might encounter a case, so she asked Qin Zhibo to follow him in advance and solve the case first...

But this time, she did feel a little softer when she saw that Conan's body had become smaller and he was unable to do what he wanted.

"As long as you use a temporary antidote to temporarily grow back to look like Kudo Shinichi, and then use Kudo Shinichi's passport to pass through customs and board the plane..."

"The flight from Tokyo to London takes about 15 hours. The temporary antidote is effective for 24 hours and can cover the entire process."

"But in this case, you can't use your identity as Conan to fly with the Maori family..."

While Haibara Ai told her plan, she took out a pill box from the drawer in front of the work cabinet.

There were several different medicines placed in the compartments inside the medicine box. She pinched out two white and green capsules from one of the compartments.

"Well, the two temporary antidotes I gave you are only enough for you to clear the level back and forth. Remember to calculate the time to take the medicine..."

"back and forth?"

Conan took the two capsules and looked at the dozen antidotes in the medicine box in Haiyuan Ai's hand. A smirk immediately appeared on his face.

"Since you have already prepared so many antidotes, why don't you give me a few more?"

"Dah!"

Hui Yuan Ai closed her eyes, closed the medicine box without mercy, and put it into the pocket of her jeans.

Seeing this, Conan also said anxiously: "Just give me more, maybe we can meet the emergency!"

"What's the urgency? You didn't go to London to show off..."

Haiyuan Ai looked coldly, "Although it has not been verified through human experiments, under normal circumstances, the effect of this temporary antidote is likely to decrease as the body's resistance increases..."

"The more times you take the antidote, the shorter the duration of its effect, until the antidote completely loses its effect..."

After Haihara Ai's threats, Conan also restrained himself a little and asked with some worry: "Does that mean it's possible for me to change back to Conan on the plane?"

"This possibility cannot be ruled out, so..."

"That's why you need to give me a few more antidotes!" Conan changed the subject and became even more excited, "I don't want to never be able to return to Japan!"

"Please, Haiyuan, just give me a few more!"

With that said, Conan made a move to step forward and grab Haihara Ai's bulging trouser pocket.

Haiyuan Ai tightly covered his trouser pockets and screamed: "Don't touch me! Pervert!"

Seeing this, Dr. A Li could only hold Conan's shoulder with one hand, smiled helplessly and comforted: "Well~ Shinichi, Xiao Ai must have some reasons for doing this..."

"But I also have difficulties!"

Conan turned his head to look at Dr. A Li, and then told the two of them about the lie he told temporarily last time and what Mao Lilan had been thinking about.

"When Xiaolan arrives in London, she will definitely meet with me!"

"So I really need these antidotes!"

"please!"

Conan bowed sharply to Haiyuan Ai, a standard 90° deep bow.

But after hearing Conan's reasons, Haiyuan Ai shook his head even more firmly.

"That would be even worse..."

"If you were dating a young Japanese girl on the streets of London in your true self, it would be very conspicuous."

"What if I get killed by Gin..."

Haiyuan Ai subconsciously wanted to say Ginjiu, but when he thought that Ginjiu was dead, he changed his words.

"...When other people in the organization see it, they will immediately suspect that you are the Japanese high school detective Kudo Shinichi who is supposed to be dead."

"Then they will further investigate the people close to you. Do you want to..."

As Haibara Ai was speaking, Conan reluctantly raised his right hand as a sign of surrender.

"Okay, you don't need to say anything, I understand..."

However, Haiyuan Ai was still worried and warned: "Also, the doctor will also go to London with you this time."

"Should I go too?" Dr. Ali pointed to his nose in confusion.

"Yes." Haiyuan Ai nodded firmly, "If you can't go to London with Xiaolan and the others, the doctor will definitely have to send you there, right?"

"And in order to prevent you from doing anything stupid while you are in London, the doctor must also follow you..."

After hearing Haihara Ai's explanation, Conan also felt that it made sense.

After all, for the Maori father and daughter, it is impossible for a primary school student to fly to London alone, and a guardian must accompany him.

"But doesn't it matter if I take the doctor away? In this case, you will only have one person left here."

"How about I ask Qin Zhibo, he should have time to take me abroad..."

Conan thought of his good partner, and with their current friendship, they went on a foreign trip together, just like a father taking his son, without any sense of disobedience.

But Haihara Ai shook his head and rejected Conan's proposal.

"No, I just want to go to Chengshi's house to stay for a few days during this period. You can just go with the doctor..."

In fact, since Ginjiu's death, Haihara Ai has gradually become more courageous and will expand her social circle appropriately.

In the past, I was worried that my identity would be exposed and Cheng Shi would be implicated, so I didn’t dare to contact him frequently.

Now she has much less worries in this regard, so she dares to take the initiative to stay at Cheng Shi's house for a few days.

Although Dr. Ali is also a family member, he cannot give her the feeling of a sister.

In response to this, Dr. Ali also smiled slightly and said that he understood.

…

Two days later, at 9 o'clock in the evening, Tokyo Haneda International Airport.

In the waiting hall, a handsome, thin young man wearing a mask and an old man with gray hair, also wearing a mask, were sitting on their seats.

The anxious two people held boarding passes in their hands and looked around carefully, waiting for the boarding time to arrive.

After these two days of preparation, Conan inquired in advance about the flight time sponsored by the rich woman named "Diana", and then asked Dr. Ali to go to the airport to buy two economy class tickets on the same flight.

Then, Conan told Mao Lilan that he had something to do temporarily and would take the next flight two hours later with Dr. Ali.

In this way, when they land in London together, Conan still has time to deal with the remaining time to grow bigger.

However, the danger of this method is that if you take the same flight, the two groups may "encounter" by chance while flying or waiting for the flight.

But the good news is that the rich woman who sponsored this trip to London for free was very generous and directly booked first-class tickets for the Maori father and daughter.

The first class cabin, both in the cabin and in the waiting area, is different from the economy class that Dr. Ali booked.

At this moment, the Maori father and daughter were resting in the VIP area in the distance, which was an independent space completely isolated from the waiting hall outside.

But there is no guarantee that Mouri Kogoro suddenly had a whim and wanted to meet a beautiful woman by chance, take a walk in the terminal hall or something...

Therefore, you still need to be extra careful.

Time passed by one minute and one second until the departure hall began to broadcast language, reminding passengers on the flight to London that they could start boarding.

As distinguished first-class passengers, the Maori father and his daughter enjoy priority boarding rights along with other first-class passengers.

Conan, who had transformed into Kudo Shinichi, watched their figures leave for a while, and then he and Dr. Agasa stood up from their seats.

"Okay, let's go too..."

One of the two of them was carrying a small schoolbag that did not fit their body shape, and the other was pushing a yellow suitcase, and walked towards the boarding gate.

But just after the two of them left their seats, two more people came to the seats where they had been sitting before and sat down.

"Uncle, did we come a little early?"

"Look at the passengers from the previous flight who have just boarded the plane..."

Qin Zhibo pushed the suitcase in front of him and stood up, then turned to look in the direction Kuroba Kaito pointed.

I saw passengers there still queuing up in front of the boarding gate, waiting to pass through. These passengers had the same destination as themselves, which was London, England.

However, the flight schedule is slightly different, and I have to take the next flight two hours later.

"What do you know, kid?"

"When doing things, you have to do things sooner rather than later. This is the wisdom of adults..."

"And it's only two hours early."

Qin Zhibo sat on a chair and used the time while waiting for the flight to think about whether there were any mistakes in the preparations for the past two days.

This time I went to the UK and had three tasks.

First, I went to the University of Brightchester in the UK to get information about the "Great Halley's Comet", especially the time of the comet's return.
