Ke Xue: Shinichi and I are childhood friends.

After giving the order, Yokomizo Sango looked at the two unfamiliar faces beside Yuya: "Who are these two...?"

Subaru Okiya and Rumi Wakasa each introduced themselves.

Yokomizo nods slightly, indicating that he has come to know him.

He turned to look at the three somewhat uneasy people beside him and began to inquire about the circumstances of the incident.

The incident occurred roughly between 15 PM and 16 PM during the afternoon break at the seaside resort, and the person who discovered the body was Maika Mogi.

It was almost evening business hours, but Shii Katsutoku and Junyama Takaki, who had gone to sleep in the storeroom, had not yet gotten up. So she and Menda Sekiyo went to the storeroom to call them.

When they arrived at the warehouse, the door was locked.

After opening the door, only Junshan Guiqi was sleeping on the sofa in the warehouse; Shii Katsutoku was nowhere to be seen.

Then they discovered a strange object wrapped in a towel in the room. When they opened it, they found the corpse of Shiii Katsutoku inside.

“I see,” Yokomizo Sango said, his brow furrowed. “Then, during the time period when the incident occurred, where were you each and what were you doing?”

Maika Mogi stated that she went to buy the pineapple juice that Shii Katsutoku wanted to drink because this type of pineapple juice was only sold in a vending machine that was very far away, and she was at the vending machine at the time of the incident.

Next was Munda Sekiyo. Between 16 PM and 15 PM, she walked to her grandmother's house to deliver medicine, a journey of about 15 minutes.

Because her grandmother's medicine had gone missing, she asked the doctor to prescribe a new one. Since there were no pharmacies near her grandmother's house, she had to deliver it to her personally.

I saw my grandma sleeping in the living room, but since I didn't have my keys, I didn't want to ring the doorbell and wake her up, so I just came back.

After returning, she stayed in the store to prepare for the opening of the adjacent business.

After Maika Mogi returned, the two of them went to the storeroom together to call for help.

Finally, there's Junyama Takaki.

He had been sleeping in the warehouse until the two women arrived, at which point he woke up.

Because the warehouse had air conditioning, Junshan Guiqi originally planned to play games inside while enjoying the cool air. However, after drinking juice and eating some snacks, he became sleepy and fell asleep once he was full.

At this point, Junshan Guiqi suddenly remembered that he had experienced similar situations a few times before, and he began to doubt whether his constitution was suitable for drinking his favorite grapefruit juice.

After the three finished speaking, Yokomizo Sango said seriously, "According to your testimonies, none of the three of you can provide eyewitnesses who can help you with alibis. In other words, all three of you could be the murderers of Mr. Shiii!"

Yuya narrowed his eyes slightly; it was another one-out-of-three choice for the attractions.

Upon hearing this, the three of them immediately showed uneasy expressions.

Menda Sekiyo immediately said loudly, "Leaving aside Kiki, if it were me or Maika who murdered Mr. Shiii in the storeroom, we would definitely wake Kiki up, right?"

Junshan Guiqi retorted angrily, "What do you mean by that? What do you mean by Guiqi? Let's not even talk about it!" His words were practically a direct accusation that he was the murderer.

Yuya asked, "Ms. Menda, may I ask what medicine you gave to Grandma?"

Mian Tianshuoliang replied, "It's a medicine for treating high blood pressure."

"What's the name of the medicine?"

Mian Tianshuoliang paused for a moment, then recalled, "It should be called nifedipine, right?"

Yuya pressed further, "Did Mr. Shiii also drink grapefruit juice?"

Mian Tianshuoliang nodded blankly.

Yuya frowned slightly: "Just as I thought."

Junshan Guiqi asked somewhat impatiently, "Is there a problem with this?"

At this moment, Shiho Miyano, who was very knowledgeable about medicine, spoke up and explained: "This should be the reason why you and Mr. Shiii have not woken up after falling asleep in the storeroom."

Everyone looked at Shiho Miyano in surprise.

Shiho Miyano explained, "Nifedipine is a dihydropyridine calcium channel blocker, and the components in grapefruit juice can inhibit the metabolism of this calcium channel blocker. This can lead to an increase in the blood concentration of nifedipine, which can enhance its antihypertensive effect and cause hypotension, which can then lead to symptoms such as palpitations, dizziness, headache, and coma."

Shiho Miyano's professional words left everyone stunned.

Although I didn't understand it, I grasped the general meaning.

That was the result of the combined effects of nifedipine and grapefruit juice on Shii Katsutoku and Junyama Takaki's coma.

Yokomizo Sango raised a question: "But how can we get them to take this medicine without them even realizing it?"

Yuya thought for a moment and then came up with a possibility: "Maybe it's a straw?"

Yokomizo was taken aback: "A straw?"

Yu nodded slightly and analyzed, "The grapefruit juice they drink is packaged in a cardboard box. As long as you remove the straw that comes with the package, put the crushed medicine into the straw, and then stick it back on, you can make someone swallow the medicine at the same time while drinking the grapefruit juice without the other party noticing."

Yokomizo Sango was somewhat suspicious: "But how could it be such a coincidence that they drank grapefruit juice laced with drugs?"

Yuya said, "It's very simple, just fill all the straws with medicine."

Yokomizo Sango exclaimed in shock, "If that's the case, what if a customer orders grapefruit juice...?"

Yu shook her head: "That won't happen, because when this store sells juice, they pour the juice from the box into a glass with ice, and they also provide a longer straw, so customers won't ingest the medicine."

"However, I think the murderer probably dismantled all the straws after committing the crime."

"I see." Yokomizo nods slightly and immediately orders an officer to check the straw.

“Hearing you say that,” Junshan Guiqi suddenly thought of something and looked at Yuya, “Mr. Shiii once said something like this while drinking juice: ‘Has this juice been sitting out for too long?’ Then he gulped down the juice.”

My mouth was full of snacks, so I didn't realize anything was wrong when I drank the juice.

He turned to look at Mian Tian Shuoliang and said angrily, "He probably never imagined that he would be killed by you by drugging him!"

Mian Tian Shuoliang was furious: "What makes you think it's me?!"

Junshan Guiqi angrily retorted, "Aren't you the only one who has this kind of medicine?!"

Mian Tianshuoliang immediately said, "Didn't I already say that I only got a new prescription from the doctor because the medicine was missing? If any of you steal the medicine from me, wouldn't you have the same way to do it?"

These words immediately aroused Maika Mogi's dissatisfaction.

The three started arguing, each claiming that the other had drugged them.

At that moment, Rumi Wakasa suddenly walked up to Shiho Miyano and said with a smile, "But you're really amazing, Tensou-kun. I'm curious where you learned about that kind of medicine?"

Shiho Miyano's heart skipped a beat, but she calmly explained, "Well, what can I do? I have a boyfriend who causes me so much trouble."

Yuya smiled and said, "Don't let Mio's appearance fool you, she's actually a very caring girlfriend."

Shiho Miyano glared at Yuya: "What do you mean by looking at me like that!" She then pretended to pinch Yuya's waist.

Yuu swayed her hips and said with a grin, "It's nothing, it's nothing."

Watching the two flirting, Wakasa Rumi lowered her head slightly, a cold glint reflecting in her glasses.

"I see. Tiancang just surprised me quite a bit, acting like a scientist from somewhere."

The two stopped playing around.

Yuya looked at Wakasa Rumi and smiled faintly, "Really? Then maybe Mio has a talent in this area."

Conan and Subaru Okiya, standing nearby, secretly observed Rumi Wakasa, a glint of shrewdness flashing in their eyes.
