Refuse to allow Conan to join the main storyline

[Choice 1: Fatal. Choice 2: Controllable. Choice 3: Permanent.]

This time the options were surprisingly simple and didn't require much thought.

Although according to the subsequent plan, what she needs most is lethality, but...

Koizumi weighed the medicine bottle in his hand and smiled: "But there is still a year left, so we can't reveal our cards too early. Then... system, I choose controllability."

The medicine bottle in his hand emitted a white light, and after a moment its properties changed again.

【Drugs that can rejuvenate people】（4+0）.

Koizumi simply poured out another red and white capsule and put it into his mouth, and as expected, he turned back into the state of a seven or eight-year-old child.

She silently felt how to use this thing, and then her expression became subtle.

Koizumi returned to the bathroom mirror again, calculating the time while paying attention to the changes in his body.

The effect of the drug still lasted for an hour, but this time, she didn't suddenly change back to her original appearance, but grew up slowly. The whole process was like watching a time-lapse documentary spanning more than ten years.

When her body was about to grow to about eighteen years old, Koizumi had an idea and deducted 100 singularity points from the savings pool, and then her body's growth was paused.

This controllable option was far more practical than she had imagined. As long as she wanted, she could even let herself stay at any age!

The cost is 100 singularity points/24 hours.

Interesting! This is really interesting!

It can be imagined that with this thing she can definitely attract Karasuma Renya's attention perfectly.

But, one hundred a day...

This is not burning the singularity, this is burning her heart, liver and lungs!

------

Consciousness returns to the system space.

Koizumi looked down at himself. Although his body had become eighteen years old, his soul was still the same as before, without any change.

In other words, it will not affect IQ!

very good!

"Quan, are you planning to use yourself as bait?"

Koizumi looked at Sakurai and smiled, "Well, it's fun, isn't it? Do you want to experience the feeling of suddenly becoming a child?"

Sakurai Izumi replied expressionlessly: "No. I have experienced it too many times."

Koizumi choked.

"How old do you plan to be when you meet Karasuma Ren?"

"In theory, of course, the younger the age, the better the effect."

"It's too dangerous! Believe it or not, Karasuma Renya might send you to the laboratory for sectioning without blinking an eye!"

Koizumi said confidently: "That's why I didn't dare to use the ability of resurrection as bait!"

Sakurai Izumi: "...Are you still going to let me praise you for being so smart? Can you please give priority to your own safety? If you become a little kid like that and go to the organization's headquarters, you will be at the mercy of others!"

Koizumi deliberately put his hands on his hips and said with a smug smile: "But it's cute, isn't it!"

Sakurai Izumi was completely speechless.

"Oh, okay, okay, I've thought about it! As long as it's done properly, it should be safe. And there's still a one-year buffer period."

"Do you really believe that Gin can buy you a year?"

"To be honest, I don't really believe it. So I will keep helping him and that gentleman strengthen their faith!"

"…What are you going to do?"

"Well, first, I will return myself to a slightly younger state, so that Karasuma Renya can notice the abnormality in me and attract his attention."

"Then let the organization be aware of the existence of Ash's vest and conduct an investigation. When the organization finds out that this guy who looks only in his early twenties is actually in his sixties and was once a researcher at the White Dove Pharmaceutical Factory, what do you think the gentleman's reaction will be?"

Sakurai Izumi's eyes slowly widened, shocked by Koizumi's train of thought.

“Then that gentleman will find out that what I lost was actually stolen by Fujiwara Yuto.

"And then, when the organization tries to capture Fujiwara Yuto, let him disappear or die? In this way, my importance will inevitably become the first, and I should naturally become the focus of that gentleman's attention."

Looking at Sakurai Izumi's stunned expression, Koizumi chuckled and said, "Of course, this is just my initial assumption. Who knows if there will be any unexpected situations in the middle? Maybe after the organization discovers my abnormality, they will rush to capture me and slice me up without waiting for Fujiwara Yuto to appear."

Sakurai Izumi: …

"Oh, don't worry, I won't reveal the secret so soon! At least I have to wait until Fujiwara Yuto's vest is fully formed before I can start this plan. If I can upgrade the rejuvenation potion to level five before I go to see that gentleman, maybe we can go straight to the final battle."

Sakurai frowned and rubbed his brows: "Then how do you plan to upgrade this thing to level five? You know how many singularities are needed from level four to level five, right? That's 650,000 singularities! What's more, according to your plan, you need to upgrade another puppet of Ash. How are you going to do it with only one year?"

"Well, first of all, I hope that after Zhu Fu Jingguang's problem is resolved, the system can give me another big red envelope!"

"What if not?"

"Then after we completely get rid of Matsuda Jinpei's fatal danger, we will definitely be able to get another red team reward."

"Are you sure you can get it done within next year?"

"...No. But at least Rum will definitely become the mayor, so I can at least get a black side reward."

"As I recall, the Black side's reward was just a one-time enhancement, right? Even if you have room to spare after upgrading Ash's puppet, there's still a big gap."

"Well, so I need to start brushing up the black side's reputation."

Sakurai looked at Koizumi's smiling face in astonishment and remained silent for a long time: "...Are you planning to change sides?"

"It's not like I'm switching sides. At least in the short term, I will try my best to maintain my relationship with the police before they turn against me."

She smiled and winked at Sakurai: "You can also brush up the reputation of both sides at the same time. If you can get a red side reputation in addition to the matter of Morobushi and Matsuda, wouldn't it be better?"

Sakurai Izumi was stunned and had no idea how to evaluate her plan.

Koizumi laughed and said, "How is it? Are you surprised? Are you surprised?"

Sakurai Izumi's expression is hard to describe.

"I'm sure both the Red and Black sides will be quite surprised..."

She shook her head and sighed helplessly: "I really don't know whether to say that you are thoughtful or heartless. Be careful not to get yourself into trouble, or both sides will suffer. If both of them attack you at the same time, your situation will be difficult."

At this point, Sakurai's eyes suddenly lit up as if he remembered something: "You arranged Morobushi Keimitsu and Furuya Rei to the core positions of the organization. Did you guess that this day would come sooner or later and arranged it in advance?"

"Ah, that's not the case. I don't have such long-term plans. What I just told you is just an idea I came up with in the past two days."

"Then why did you arrange those two people like that? Wouldn't it be better to let them be peripheral members, or just bring them under your own command?"

"What are you doing? Are you staying here to make things difficult for me? Just let them go to where they should go."

Koizumi chuckled and said, "We have to thank Comrade Akai Shuichi for temporarily leaving the stage, which gave Zhufu a chance to work."

Sakurai Izumi sneered: "Why don't you send him a thank you letter!"

This was originally just a joke, but unexpectedly, Koizumi narrowed his eyes and thought about it, then smiled and said, "Well, this is possible."

Sakurai Izumi: …

Ah, this guy is starting to cause trouble again.

But think about it, her entire plan for next year is to do something serious, so what does a mere thank-you letter mean?

"But I still have to say that it's really dangerous for you to use yourself as bait."

Sakurai Izumi suppressed the smile on his face and said seriously: "He will die. Guess how many times he will die?"

Koizumi muttered a little guiltily, "Besides, it's not like I haven't died before, I'll just get used to it."

"Don't get used to this kind of thing!"

"Oh, I'll try my best to avoid this situation!"

Sakurai Izumi had no idea what to do with her, so he could only stare and sigh: "I hope you can really get Matsuda's red reward next year."

Koizumi sighed, "I think so too. I'll feel relieved if I can get this over with quickly, so I don't have to worry about him all the time."

As she said that, she rolled her eyes, came up to Sakurai and said with a smile: "I've wanted to ask you for a long time, you seem to be particularly interested in Matsuda, do you like this type?"

Sakura glared at her and said nothing.

"To be honest, when Dr. Tani was young, wasn't his temper somewhat similar to Matsuda's?"

Sakurai: “…Yeah, a little bit.”

"Well, now that I've remembered everything, let's take advantage of Gin letting me leave Tokyo and go meet him?"

Sakurai: …

Koizumi looked at her with a smile and said leisurely, "Hey, come to think of it, didn't you say before that you wanted to be my stepmother? It seems like your words have come true."

"puff!"
