Refuse to allow Conan to join the main storyline

Looking at the man in a white coat walking into her room, the two fully armed bodyguards in black following him, and an extra can of injection in the incubator, Koizumi knew that she had finally gotten Karasuma Renya's backup plan as she had wished.

Come to think of it, she just secretly told Vermouth the two key words "truth serum" and "Subject No. 690" last night. Did she just pass the news to Karasuma Renya's ears?

Sister Bei is really fast.

"Hello, Master Mello. I will be the one drawing your blood today."

Koizumi looked at the scholarly face in front of him and frowned slightly, "Why did you change people? Where is the person who drew my blood before?"

The man bowed slightly to her and said in a serious tone, "First of all, please allow me to introduce myself. My name is Tetsuya Uesugi, and I am the top leader of Mr. Karasuma's medical team."

When he mentioned the name, the man blinked slightly at Koizumi.

Koizumi raised the corner of his mouth and smiled: "Ah, I know, I know."

Upon hearing this, the expression on "Uesugi Tetsuya's" face froze for a moment.

You know this again?!

Koizumi smiled nonchalantly: "It doesn't matter who it is."

No matter how you dress up, your smell will not change.

But, sister Bei, I don't find it strange that you were able to sneak into Karasuma Renya's medical team, but... the top person in charge? That person didn't notice the flaw?

"I just want to know why the change was made."

"Uesugi Tetsuya" said with a straight face: "...Because this blood draw requires a special step first, in order to allow you, Mello-sama, to accept this change with peace of mind, I will explain it to you in general."

Koizumi nodded slightly and pointed at the extra injection in the incubator with his chin: "Is this what you mean by change?"

"Yes."

"Uesugi Tetsuya" nodded and began to talk nonsense in a serious manner: "Lord Mello, the results of the previous two blood draws show that your blood activation level has not yet reached its peak. In order to activate your blood to a higher level without harming you, we will use this newly developed catalyst. This catalyst can stimulate the potential of your blood in a short period of time, thereby achieving the effect we expect."

Koizumi folded his hands in front of his chest and looked at him with a half-smile: "Oh, a catalyst... is that all? It doesn't sound very reliable. Are you sure this thing really just stimulates the potential of my blood?"

"Uesugi Tetsuya" looked serious and nodded solemnly: "Yes, Master Mello. This is a research project that has been started since the time of Master Vermouth. Since your blood activity is far higher than Master Vermouth's, although this catalyst may not achieve satisfactory results when used on Master Vermouth, it will definitely achieve the most perfect effect if used on you."

"Uesugi Tetsuya" remained calm and composed from beginning to end, and responded with ease: "I can assure you with my 45 years of medical ethics as a doctor, Uesugi Tetsuya, that the effect of this medicine is just as I described."

Oh my, she is indeed a world-renowned actress, so awesome!

Koizumi couldn't help laughing, and simply looked at the actor opposite him with a meaningful expression without saying a word.

For a moment, the atmosphere in the room seemed to freeze, and the tense atmosphere became increasingly thicker.

Karasuma Renya, who was watching the situation closely in front of the monitor, clenched his fist silently. He felt a little uneasy about Koizumi's silence and couldn't help muttering to himself, "What is this woman thinking about?"

In the room, Koizumi, who had been silent for a long time, finally broke the deadlock.

She sneered: "Is Karasuma Renya planning to attack me? He really can't wait. But, Dr. Uesugi, do you think I will believe you so easily?"

Karasuma Renya's heart tightened instantly.

I can't even fool her? Is it really necessary to rely on force to subdue this woman?

But the rubbish around him was not able to match Melo's strength...

Tsk, did he attack Gin too early?

However, the situation on the monitor did not develop as Karasuma Renya expected. His chief doctor, Dr. Uesugi, lived up to his reputation as a "poker face" and remained calm and stable: "How can I make you believe what I say, Master Mello?"

Koizumi was playing with a blade that came out of nowhere, and his threat was self-evident: "Since you are so confident, why don't you give yourself an injection first and let me see how it works?"

Karasuma Renya secretly cursed in his heart, he didn't expect Mello to give such a reaction.

As expected, I should use the last resort immediately...

However, before he could call for help, he heard "Uesugi Tetsuya" say without hesitation: "Sure."

Karasuma Renya's eyes widened in shock, and his body sat up straight involuntarily, staring at the monitor screen, and saw that "Uesugi Tetsuya" actually rolled up his sleeves.

"Master Mello, before I demonstrate to you, please allow me to explain to you. In order to improve the user's feeling and reduce the pain that may be caused during catalytic activity, this potion contains some anesthetic ingredients."

Koizumi raised his eyebrows and looked at him with a half-smile: "Oh."

"Uesugi Tetsuya" continued, "But please rest assured, the dosage of these anesthetics has been strictly controlled. It will not cause any burden to the human body, nor will it make you comatose. Next, I will demonstrate it to you."

After saying that, the man stabbed the needle of the syringe into his arm without hesitation.

Before he could push the piston, Koizumi suddenly laughed and said, "That's enough, stop it."

"Uesugi Tetsuya" looked up at her and said, "Lord Mello, the demonstration is not over yet. You can observe the changes after my injection first, and then make a final judgment."

"Okay, stop wasting your energy." Koizumi waved his hand and stretched out his arm. "Do whatever you want to do quickly, and leave me alone in peace!"

She muttered in dissatisfaction: "If I had known it would be like this, I would never have come back with Gin. It's so annoying!"

Uesugi Tetsuya silently pulled out the needle stuck in his arm, replaced it with a spare needle, and confirmed with her again: "Then, Master Mello, I will give you the injection."

Koizumi glared and said impatiently: "Stop talking nonsense and hurry up!"

The injection was completed quickly and smoothly.

"Uesugi Tetsuya" put away the syringe, nodded slightly to Koizumi and said, "Please wait a moment, Master Mello. I can proceed to the next step of drawing blood after the medicine starts to take effect."

Koizumi let out a "tsk" and leaned back on the sofa, picking up the novel he was halfway through.

Karasuma Renya didn't expect that things would take such a sudden turn, and Dr. Uesugi actually handled Mello's temptation perfectly. Seeing him push the tube of medicine full of all his expectations into Koizumi's arm, Karasuma Renya couldn't help holding his breath, staring at the monitor without blinking, for fear of missing even the slightest change.

However, time seemed extremely long at this moment, and every second seemed as unbearable as a century.

Seeing that Koizumi was still sitting there steadily and did not show the reaction he expected, Karasuma Renya gradually felt a little uneasy.

what happened……

What happened next? What happened next!

What about the intolerance reaction?

Melo, please fall down quickly!
