Refuse to allow Conan to join the main storyline

Karasuma Renya looked at the monitor in front of the bed, his face so gloomy that water seemed to drip out.

Two days passed, and things had developed completely contrary to his expectations.

First, his medical team drew blood from Melo twice in the name of testing blood activity. Because the amount of blood drawn each time was not large, Melo did not show any resistance but was quite cooperative.

The good news is that, despite not going through the strange process of "seriously injured - wandering around - healing", Mello's blood itself is extremely active and fully meets the standards for direct use.

Moreover, according to experiments on mice, after dialyzing Melo's blood samples, the mice actually showed signs of degenerative reverse growth.

In other words, if Karasuma Renye uses Melo's blood for injection, there is a great possibility that it will have the same medicinal effect as the rejuvenation drug.

Karasuma Renya felt both surprised and annoyed.

To his surprise, after decades of waiting, he finally saw hope of rejuvenation. To his dismay, with Melo's current attitude, it was impossible for him to cooperate with him in completing the blood transfusion operation.

Perhaps, she was willing to cooperate. But it was also possible that after seeing him in person, she would rush up and kill him!

Based on his understanding of Melo and Melo's attitude towards him, this possibility is quite high.

Even if there was only a one percent chance, Karasuma Renya would not dare to take the risk!

But on the other hand, his attending doctor also told him that because Melo was an experimental subject, his body had developed a strong resistance to ordinary drugs, and ordinary anesthetic sleeping pills could not achieve the expected effect on him. The drugs independently developed by the organization, such as APTX4869, were too lethal. If Melo was given it rashly, it might cause Melo's blood to be contaminated, causing his own active ability to lose its healing effect, so it was not recommended.

Therefore, before finding a way to subdue Mello and make her completely lose her fighting power, Karasuma Renya could only watch his "ginseng doll" eating and drinking well and living a leisurely life every day, but he didn't dare to eat anything!

On the other side, it's Gin's side.

Although Karasuma Renya injected more fighting power into the duel arena, Gin not only remained safe and sound, but he even seemed to be unaware of the pressure.

It was obvious that the manpower he deployed should be comparable to Gin's in terms of combat effectiveness based on the test results, but Gin was able to escape from the battle unscathed time and time again!

Especially at night, this man would shuttle through the Twilight Pavilion like a ghost, accurately determining the enemy's position every time and delivering a fatal counterattack. All challengers seemed to be vulnerable in front of him.

It was obvious that Mello had never provided any form of assistance to Gin. The only time the two met was in a restaurant. Mello went over, patted Gin's thigh, mocked him a few words, and left.

However, her ridicule seemed to have aroused Gin's ferocity, and he became more efficient in killing his enemies...

What exactly is going on?

Gin's fighting skills are so much better than others. Is this just the result of years of practical experience?

But it was obvious that after he obtained the code name and acted alone, his opportunities for actual combat were less than a quarter of what he had before leaving the villa, or even less.

Could it be that some unexplained changes have occurred in Gin?

Karasuma Renya even wanted to tie him up to the experimental table and perform an anatomical study on him.

On the other side, Koizumi was also depressed.

Two days have passed, and apart from drawing a few tubes of her blood, Karasuma Renya has no intention of doing anything to her?

After discussing it with Sakurai, she suddenly realized the possibility of "drug resistance".

In other words, maybe it's not that Karasuma Renya doesn't want to attack her, but that he really doesn't have a good solution?

...What should I do? This is too bad!

Koizumi was feeling depressed, but Sakurai reminded her of a possibility.

"Quan, do you remember the first time you met Rum?"

At this time, Koizumi was throwing his body on the bed to "take a nap". He entered the system space to discuss the latest situation with Sakurai. When he heard Sakurai's words, he was stunned for a moment.

"Hey, you mean the time we met in that western restaurant?"

"Yes." Sakurai asked anxiously, "Do you still remember what happened at that time?"

"Yes." Koizumi nodded, recalling and saying, "I had been arguing with that guy Rum, and then he suddenly asked me to take a lie detector test. He injected me with a lie detector drug developed by the organization. What's it called... truth serum?"

"Yes, do you remember what happened after the injection?"

"Well... I remember that my body had an abnormal reaction. After I woke up, my heart rate and breathing became extremely abnormal. I felt like I was about to die. If it weren't for the system saving my life, I might have really died that time."

After she finished speaking, Sakurai nodded solemnly, "You really don't remember."

Koizumi was stunned: "Huh?"

Sakurai said seriously: "Izumi, listen to me, the real situation at that time was like this..."

It was the first time that Koizumi understood everything that happened in the secret room from a third-party perspective, from the changes in her body after the injection of the truth serum, to the questions Rum asked her and her own reactions, to Rum's murder and her gradual awakening.

"Up to this point, your body's changes and reactions were normal. The problem was the second injection of the drug that Rum had someone inject you with." Sakurai deliberately spoke in a more serious tone, "Your body had an abnormal reaction after the second injection of the drug. The researcher at the time drew a tube of venous blood from your arm."

"I remember!" Koizumi said hurriedly, "I handed over the tube of blood. My original intention was to let the public security department study it to see if they could find out the composition of the drug, but there was no news about it later."

"Yes." Sakurai nodded, "I was watching carefully here at the time, and I remember very clearly what the researcher of the organization said at the time."

Sakurai paused for a moment before continuing, "He said this was the first time he had encountered an abnormal situation after the modified EME detoxification. He didn't know if it was due to your constitution or if something abnormal happened when the drugs were offset. He said the drug ingredient that might be problematic is called Scopolamine."

"Scopolamine..." Koizumi frowned and repeated the unfamiliar pronunciation, "What is this?"

"I used to work in the organization's laboratory, so I happen to know what it is." Sakurai took a deep breath, "Scopolamine can be considered an anesthetic. It has the effects of inhibiting glandular secretion, dilating the pupil, and relaxing smooth muscles. It is often used for pre-anesthetic medication, motion sickness, Parkinson's disease and other diseases. However, improper use may cause some adverse reactions. You must have developed an intolerance to this alkaloid drug component at the time."

Koizumi's eyes widened in astonishment, and after a while he suddenly jumped up and began to spin in circles.

"In other words, if Karasuma Renya could learn about the problem with my experiment, he would definitely find out that I am intolerant to scopolamine and use this against me! Then...then the result we want would be perfectly achieved!

"Oh my god! Sakurai, you really..."

Koizumi's eyes sparkled with excitement. He rushed forward and hugged Sakurai tightly, kissing her hard on the face twice. "Great! We have a solution, this is it! What number did Rum say I was? Yes, number 690! I am the 690th subject of the organization's self-developed truth serum!"

Sakurai interrupted hastily, "Don't get too excited. The question is, how do we let Karasuma Renya know about this? You can't just go and tell him yourself, right?"

Koizumi laughed and said, "I can't do it, but someone can!"
