Refuse to allow Conan to join the main storyline

Vermouth came back in less than half an hour, holding a middle-aged man who was drunk and in a semi-comatose state.

As soon as she saw the rough skin and wrinkles on the man's face, Koizumi knew that Sister Bei really understood her thoughts.

Vermouth threw the man on the sofa, and Koizumi gave him another bottle of anesthetic, making him completely unconscious.

Vermouth took off her wig and sniffed the alcohol on herself with disgust: "You start first, I'll go clean up."

"it is good."

Without saying a word, Koizumi took the gold foil essence with added ingredients and was about to apply it on the man's face, but was stopped by Vermouth.

"Alas, you really have no experience at all."

Sister Bei casually took out a marker from her pocket and handed it over: "Here, it's ready for you."

Koizumi took it, looking confused.

Seeing that she really didn't understand, Vermouth sighed helplessly, took the pen back, and drew a vertical line along the man's forehead and nose.

"Paint one side and leave the other side for comparison. Got it?"

Koizumi suddenly realized: "That's right! Sister Bei, you are really thoughtful."

She took the marker and drew a few more horizontal lines on the man's face to divide it into more areas.

Vermouth asked in confusion: "What is this for?"

Then she saw Koizumi dragging over a piece of paper with several lumps of essences on it that looked no different.

As Koizumi applied the paint to the grid on the man's face, he explained, "I thought about it and decided to experiment with different ratios to see how much of a difference it would make."

Vermouth nodded: "Yes, that's right. You go first and remember to mark the quantity. I'll be back when I'm done."

"it is good!"

Ten minutes later, Vermouth came back in a bathrobe and wiped her hair, and saw Koizumi squatting beside the sofa, staring at the man's face in a daze.

"How's the effect?"

Vermouth poked his head out to take a look.

First, obvious steam is slowly rising from the area marked as 100%, and that small piece of skin really seems to have returned to its childhood, becoming extremely tender, smooth and elastic.

Compared with areas where drugs are not used, the difference is almost that between infants and middle-aged and elderly people.

Then, in the area marked as 70%, there is still obvious steam, and the difference in effect from 100% is very small and almost negligible.

In the 50% area, the steam becomes less, but the effect is still similar to that of 100%. There is a difference, but it is very small and can be completely ignored.

After that, the drug content gradually decreased until it reached 10%...

There is no obvious steam, but when you put your hand on your skin you can still feel the heat emanating from it.

As for the changes in skin texture, it still looks exaggerated, as white, tender and smooth as a baby's.

The two men stared at the areas for nearly an hour, watching the skin gradually age, dry out, develop fine lines, then deeper wrinkles, and then return to its original state.

Koizumi scratched his head and muttered to himself, "Is 10% still too much? And without a full face treatment, I can't tell whether it's just my skin that's getting younger or whether I'm getting younger."

She picked up a little and rubbed it on the back of the man's hand.

This time, the effect of the essence had probably worn off, and the man's skin did not change at all.

So Koizumi broke open another capsule, picked up a little bit of powder with the dagger and threw it in, then started stirring again.

Vermouth watched silently, the expression on her face no longer showing the initial excitement and eagerness to try.

She stood up and walked to the side, lit a cigarette, stared at Koizumi's serious expression thoughtfully, and finally couldn't help but say: "No matter what it becomes, it will return to its original state when the time comes. So what is the meaning of this experiment?"

Koizumi answered without even looking up: "First, the effect of this thing on me is completely different from that on ordinary people without a system, so we still need to experiment."

She applied a little of the mixed gold foil essence on the back of her hand, but it really had no effect at all.

"Since it doesn't work on me, it certainly won't work on you, Sister Bei. We can only find another test subject. Secondly..."

This time, in order to see whether the fresh mixture could change the age of the user, Koizumi simply did not leave any area for comparison and directly smeared the man's face.

"Although I can make it permanent, it's better to find out the approximate ratio before that. This will reduce the consumption of test materials."

Can it become a permanent effect?!

Hearing this, Vermouth's heart suddenly jumped: "...What does permanent effect mean?"

Koizumi turned around and smiled at her: "That's what that gentleman wanted, to be young again."

Belmod:! ! !

He sat there for a long time, holding the cigarette, not moving. “Can you really do that?”

She let out a long breath and said firmly, "You want that gentleman to take this medicine, and then take the opportunity to poison him."

Koizumi nodded. "That was the original plan. But even if I provided a lot of experimental data, Karasuma Renya might not believe me. And human experiments take too long, and too many people involved can easily lead to problems. So I thought, why not provide the data in a way that he can easily accept."

Vermouth nodded and continued, “You want to open a beauty salon like Sarah Chapman’s and turn all the customers into your experimental subjects?

"If your customers are celebrities or well-known figures, you can use their results to spread word of mouth and expand the influence and reputation of your beauty salon, thereby gaining more customers who will come to you on their own initiative. Moreover, these people are living experimental subjects and walking experimental data, which are persuasive enough to make that gentleman trust your 'research results'."

Koizumi's eyes lit up when he heard this, and he exclaimed in surprise, "What a good idea, Sister Bei! I didn't think of the beauty salon thing!"

"Oh? So what was your original plan?"

“I want to develop a new beauty product to sell in the market.”

Vermouth was simply shocked: "...You are even crazier than I thought."

She swallowed involuntarily: "You, you are going to pull out everyone in Tokyo to endorse you."

Koizumi sneered: "I'm afraid that even if everyone in Tokyo can't make that person feel at ease.

“But it doesn’t matter. If there aren’t enough people in Tokyo, we’ll promote it throughout Japan. If there aren’t enough people in Japan, we’ll continue promoting it overseas.

"You can get experimental data and make money at the same time, killing two birds with one stone.

“Everyone in the neighboring country of Korea has appearance anxiety, so my products will definitely be very popular there.

"With the whole country's efforts devoted to human experiments, I don't believe that gentleman can find fault with it!"

At this time, the man on the sofa looked like he had returned to his teens, but his face shape and body had not changed at all.

"It seems that if it is only used externally, it will only affect the skin. However, this effect still seems a bit exaggerated.

“It will be necessary to perform a dissection later to confirm the condition of the internal organs and bones.

"...Ah, where was I just now?

"Well, anyway, I was thinking that making beauty products was too troublesome, and tracking the effects of product use was also a hassle. Sister Bei, the beauty salon you suggested just solved my problem completely!

"I will go straight to the high-end and gain the greatest influence in the shortest time. After I gain a reputation, I will use hunger marketing to whet the appetite of more people. After all, what you can't get is the best, right?

"Then let them fight, fight as hard as they can, fight till their heads break!

“The more people buy it, the more popular it becomes, and I don’t even need to do any promotion!

“After we become famous, we can then launch a weaker version of the product for the mass market. Isn’t that a natural thing?

"Heh, people all over the world are getting younger and prettier, and there are thousands of 'human experiment subjects' everywhere. I don't believe that Karasuma Renya won't be tempted!"

"When the time comes, no matter whether that bastard intends to take medicine or use my blood, I will make sure that he dies!"
