"Stop struggling, this is all for your own good."

Ai Haibara watched Conan running around on the rooftop with a blank expression, calmly closing in step by step.

A lab mouse should have the awareness of a lab mouse; how can it disobey its owner?

The seemingly ordinary multi-purpose backpack behind her suddenly seemed to come alive, slowly transforming into two gleaming, intricately constructed mechanical hands.

The two mechanical arms, like two nimble venomous snakes, rushed towards Conan at lightning speed.

Conan reacted quite quickly, managing to evade capture twice.

However, it only happened twice.

"Why are you running? Are you trying to get some exercise and improve your blood circulation?"

Ai Haibara spoke coldly as she walked up to Conan, who was being held in mid-air by a mechanical arm, and raised the syringe in her hand.

The needle tip reflected a chilling light in the sunlight.

"No, absolutely not, Haibara, you can't be so cruel!"

Even with a robotic arm gripping his neck, Conan continues to try to resist.

“This isn’t cruelty…” Ai’s gaze paused calmly on his arm for a moment, her eyes completely unwavering, like an extremely composed scientist facing her experimental subject. “This is called sacrificing oneself for science.”

As soon as she finished speaking, she swiftly and accurately inserted the needle into Conan's vein. The cold needle pierced the skin without mercy and disappeared into the blue blood vessel.

"Aaaaaah!!!"

With a scream from Conan, the rooftop gradually fell silent.

On his arm, the skin around the syringe began to turn an abnormal white, contrasting sharply with the slightly reddened skin around it.

Inside the syringe, bright red blood was slowly rising.

The scene was too bloody, too brutal, too terrifying...

Not suitable for children.

...

A few minutes later.

Ai stared intently at the rising column of blood until the syringe, thicker than an arm, was completely filled with blood, then she nodded in satisfaction.

Then, she calmly pulled out the needle and pressed the piston handle to squeeze out the excess air.

During this process, due to the compression of the piston, the blood in the syringe was pressurized, and a few drops of blood spurted out and fell to the ground, forming a small patch of glaring red.

Seeing Conan's pale face, as if all life had been drained from him, Ai waved her hand, and the mechanical arm retracted the all-purpose backpack.

Having lost his support, Conan fell heavily from the air and rolled twice on the ground.

He successfully suffered a second injury.

"Don't worry!" Xiao Ai's mood improved a lot after obtaining the experimental materials, and she comforted her, "Donating blood appropriately is good for your health."

She can vouch for herself, as a scientist, that there is absolutely no problem with that statement.

This is a scientifically verified fact.

Conan, lying on the ground, twitched.

My inner voice was screaming, "You bastard, you know about donating blood appropriately?!"

This guy practically drained himself dry; he could be considered to have donated blood properly!

He felt as if his body had been hollowed out, weak and powerless, his head was spinning, and he felt like he was about to faint at any moment.

After Ai placed the syringe into the capsule, she looked down and glanced at Conan, who was staring intently at her. "Do you have any objections?"

Conan: "..."

silence……

He wouldn't dare voice his opinions even if he had them!

Don't think he didn't see it just now; there was a syringe sticking out of that backpack!

"Good that you have no objections. Once the antidote is made, I'll give you the credit."

After saying that, Ai walked to the rooftop door, turned her body to the side, and then opened the door.

The next second...

"Ouch!" Yuan Tai's fat body rolled forward like a ball of flesh, letting out a painful cry.

"It hurts!" Ayumi was pinned down by Genta, her little face scrunched up, her voice filled with grievance.

"Genta, you're so heavy!" Mitsuhiko, who was also being squeezed and swayed, couldn't help but complain as he tried to break free from the pressure of the two of them.

The three little ones, who had been eavesdropping at the door for half a day, stumbled in together.

Ai frowned slightly as she looked at the three people huddled together. "What are you doing here?"

"We...we're just curious."

Genta stammered, feeling flustered under Ai's cold gaze, unsure of what to do with his hands and feet.

Ayumi quickly explained, "We heard Conan's voice and were worried that something had happened to him, so we came to check on him."

Her eyes were wide open, filled with sincerity, trying to convince Ai that their motives were pure.

Mitsuhiko nodded in agreement, "Yeah, yeah, where's Conan?"

As they spoke, the three of them looked around the rooftop, but they didn't see a single person.

"Heh~" Ai smiled and pointed, "Under your butts."

The three children were startled and quickly got up. They saw that Conan was being pressed down, his face was ashen, and he was breathing heavily.

Her body, already weakened by excessive blood loss, was now in even worse shape.

It's truly a case of misfortunes never coming singly, and a broken ship encountering a headwind!

"Conan, are you alright?" Ayumi asked cautiously.

The other two scratched their heads awkwardly, saying, "Sorry, Conan."

Conan didn't want to say a word. After a long pause, he struggled to get up from the ground.

He felt he must have committed some terrible sin in his past life, otherwise why would he have encountered these scoundrels in this life!

Each and every one of these seems to be there specifically to torment me.

"Stop dawdling here and get back to class."

Ai crossed her arms and looked at the three little ones surrounding Conan, wanting to ask what had just happened, and gave a command.

"good!"

The three children quickly helped Conan, who was unsteady on his feet and weak, walk towards the classroom.

After everyone had left the rooftop, Ai followed them out, then turned around and locked the door.

You have to close the lock yourself if you open it.

She didn't want any mischievous children to run upstairs because of a moment's carelessness.

If something unexpected happens, that would be terrible.

After all, rooftops are inherently dangerous. Although Ai usually seems indifferent to many things, she is very cautious when it comes to matters of safety.

...

For the rest of the day, Conan lay listlessly on his desk.

The teacher was lecturing at the podium, and the students were all listening attentively or occasionally discussing questions in hushed tones. Only Conan seemed to have been detached from the world of the classroom, and he didn't feel a little better until school was over.

No wonder they say he's the spokesperson for death; he's got a really good constitution.

A normal person would be paralyzed and unable to move after having so much blood drawn, and would even have difficulty breathing.

Conan, however, only needed one day of rest to barely recover some of his energy and was back to his usual lively self.
