Ke Xue: Shinichi and I are childhood friends.

Just when Masumi Sera was about to ask what a chipmunk was, Kudo Shinichi's face suddenly changed. He covered his chest and gasped for breath, his face full of pain.

"What's wrong with you?" Sera Masumi was a little dazed.

"Is your cold getting worse?" Youya hurried over to support her and called out to Mao Lilan, "Xiaolan, come here quickly."

"Ah, what's wrong?" Mao Lilan walked over puzzledly and was shocked to see Kudo Shinichi's appearance. "Shinichi, what's wrong with you?"

"I feel a little uncomfortable." Kudo Shinichi grabbed Mao Lilan's hand and said in a low voice, "Quick, take me away from here."

Mao Lilan understood immediately and said, "Then I will help you go back to your room to rest."

Kudo Shinichi turned half his head and said to Yuya, "I'll leave the case to you."

Yuya nodded slightly, "No problem, go ahead."

He frowned slightly. What was going on? Logically, the effect of the medicine shouldn't have ended so quickly. Could something have happened to Shinichi's body?

I need to let Shiho check it out carefully.

Thinking of this, Yuya turned his head slightly and winked at Miyano Shiho.

Miyano Shiho nodded in understanding, but did not take any action.

"Are you okay?" Sera Masumi shouted from behind.

"It's okay, leave it to me." Ran Mouri held Shinichi Kudo's shoulders and dragged him away.

Masumi Sera looked at Kudo Shinichi's back as he disappeared around the corner with a deep gaze. Suddenly, she realized that someone was looking at her. She turned around and found that there was no one there.

You was also talking to the three people, seemingly asking for details about the incident.

Sera Masumi thought to himself that Kudo Shinichi's condition was obviously not caused by a cold. Although he coughed from time to time and his voice was a little hoarse, Sera Masumi could still see that most of it was fake.

Considering what her mother found out, that in the list of people who passed the London security check, there was only Kudo Shinichi and no Edogawa Conan, she had reason to suspect that the antidote that turned Conan back into Kudo Shinichi was temporary.

Now Kudo Shinichi is suddenly in this situation again. Could it be that the antidote has expired?

Masumi Sera calculated that from the time they met in the morning until now, it was probably only about 12 hours. If last night was included, it would be less than 20 hours.

This antidote is completely unfinished.

After a while, Ayanokouji and his subordinates came to the hotel.

Ayanokouji nodded slightly towards Yuya: "Detective Kamiya, long time no see."

Yuya: "...Inspector, we just met a few days ago."

"Isn't that so?" Ayanokouji smiled noncommittally. He walked into the room and looked down at the body on the ground. "The deceased was stabbed in the heart, and there are two large lumps on the forehead. This method of killing is really unusual."

He turned to the remaining four people and said, "We are going to collect evidence at the scene now. You guys should go back to your rooms and stay quiet."

His expression was somewhat heavy. "After all, the victim and you guys are all celebrities in your respective fields. I guess it will cause a big commotion tomorrow morning."

"I understand." The four of them went back to their rooms obediently.

Ayanokouji looked at Yuya: "So, what about the code?"

Yuya quickly handed over the code paper.

Ayanokouji looked down and heard, "Squeak, squeak!" A chipmunk came out from Ayanokouji's arms, climbed onto his shoulder nimbly, looked at Ayanokouji, and called out to Yuya twice.

Yuya smiled and waved, as if greeting the chipmunk.

Masumi Sera looked at this scene, blinking her small eyes in confusion.

She thought the chipmunk Yuya was talking about was the inspector's pet and never thought he would carry it with him.

By the way, is it really okay to bring pets to the crime scene?

Chipmunk Police Department?

···

On the other side, Miyano Shiho came to the empty room prepared in advance.

In the room were Conan, who had turned back into a child, and Ran Mouri, who looked worried.

Seeing Miyano Shiho come in, Mao Lilan quickly stood up and asked worriedly: "Mio-chan, is New Conan okay? He looked so painful when he was screaming just now."

She just witnessed the whole process of Shinichi turning back into Conan, and she was completely confused.

The scene that only appeared in movies actually happened before my eyes.

This is too unscientific!

Miyano Shiho glanced at Conan and said, "It's okay, this is a necessary part of the transformation process." Then she took out a syringe from her pocket and walked towards Conan.

Conan was startled when he saw the needle flashing with cold light, and he dodged backwards desperately: "You, what are you going to do?!"

Miyano Shiho said calmly, "In order to better develop the antidote, I need to collect a blood sample from you just after you turned into a child to see if there is any difference from your normal blood."

Seeing Conan's resistance, Miyano Shiho smiled evilly: "Conan, you don't want to be a child all your life, do you?"

Conan couldn't help but shudder. Knowing he couldn't hide, he could only stretch out his arms and yell in a very arrogant voice: "Oh, I get it. It's up to you!" Damn freak scientist!

Miyano Shiho chuckled, walked over, inserted the needle, and then drew a tube of blood.

Mao Lilan on the side saw her eyebrows twitching.

"Hiss!" Conan gasped and exclaimed, "Is it necessary to smoke so much?"

Miyano Shiho raised an eyebrow: "Any objections? Don't you want the antidote anymore?"

Conan choked, shrank his neck and dared not speak.

After Miyano Shiho finished drawing blood, she looked around and asked Conan, "Where is that person?"

Conan was stunned for a moment, then suddenly realized: "Ah, you persuade the department, he is eating outside and will come over later."

Miyano Shiho nodded to show that she understood, and looked up and down at Conan, who was still wearing Kudo Shinichi's uniform, and asked, "Then how are you going to get back to your room? It will take at least 8 hours before you can take the next antidote."

"This..." Kudo Shinichi was stunned. He had never thought about this question.

He thought for a moment and said, "How about having Yuya help Hattori change his outfit?"

Miyano Shiho spread her hands and said, "He's working on a case and doesn't have time to come. Besides, we don't know when it will be over. Tengu killing people sounds like it's not easy to solve."

"Ah, this..." Conan didn't know what to do for a moment.

Miyano Shiho raised the corner of her mouth and said calmly, "Why don't you just not go back to your room tonight?"

"Ah? That won't work," Conan retorted subconsciously.

"Why not?" Miyano Shiho raised an eyebrow at Mao Lilan, "Isn't there a ready-made reason?"

"Ah?" Conan and Ran Mouri looked at each other in confusion, then suddenly understood something and their faces turned red.

Mao Lilan hesitated and waved her hands: "How can that be possible! If I don't go back for one night, everyone will misunderstand!"

"What's the misunderstanding?" Miyano Shiho tilted her head and asked in a puzzled manner, "Yuya and I didn't go back to our room. When people asked about it, we said we were on a four-person date and were out looking at the stars. We ended up going back too late and worried about disturbing the students in the room, so we booked two other rooms."

"This reason should be reasonable, right?"

"Ah..." Conan and Ran Mouri were stunned, blinking their eyes and not knowing what to say for a moment.

"has a problem?"

The two men shouted guiltily: "No, no, this is fine!"
