Refuse to allow Conan to join the main storyline

Koizumi's original plan for a breakthrough was to use the cars in the parking lot as cover, sneak into the vicinity of the gate, use bombs to create some chaos, and then slip in through the gate while the enemy's attention was diverted.

Or find a lone guy, knock him out, put on a mask and make a direct attack.

However, one of these two methods requires too much time to prepare, but Gin only gave her forty minutes, and the other requires spending singularity points, but it always feels a bit of a waste to spend singularity points on this.

Koizumi weighed the options in his mind and decided to use a third, more exciting way of playing.

Returning to the back of the building, Koizumi observed silently for a while and figured out the pattern of the patrol team and the strong light scanning on the roof.

There were indeed gaps in the defense, but they were brief, no more than half a minute.

For this spacious open space and closed building, such a short error is basically difficult to exploit. It is impossible for someone to break into the building in half a minute unless some violent means are used.

But what is the difference between such infiltration and a frontal breakthrough?

It can be said that the security team under Kenichiro Nozu has done an excellent job.

However, this excellence is only for ordinary people. But Koizumi, who has a cheating device, is not within the scope of this kind of experience.

No matter how strict Kenichiro Nozu's security measures are, they are only used to protect against people, not against a cat.

Especially a cat with clear goals and special abilities.

Koizumi first threw a 5 yen coin at her feet so that she could retreat in time if she encountered an emergency during the operation.

Then, she took out a 5-yen coin and tossed it a few times. When the timing was right, she used the skipping stone technique to throw it toward the building.

A 5 yen coin weighs about 4 grams and can be thrown about 10 to 20 meters with the right skill and strength.

It is estimated that Koizumi is currently more than 30 meters away from the building.

Koizumi's coin flew more than ten meters, and after landing on the ground, it continued to bounce forward a short distance.

Someone who happened to be patrolling nearby turned around and looked around after hearing the noise.

The patrol team member walking in front of him turned around and asked, "Hey, what's going on?"

The man scanned the area again with a flashlight, but still found nothing, so he turned off the flashlight and followed his team: "No, nothing."

Koizumi was not affected at all.

She hid in the shadows, waiting for the opportunity, while silently checking the five-yen coin in the storage space.

Nearly a minute later, there was finally a gap in the enemy's patrol, and Koizumi took action without hesitation.

First, she flashed to the spot where the 5-yen coin landed in front of her, and then immediately threw the third 5-yen coin in her hand diagonally upward.

When the coin reached the highest point, Koizumi flashed into the air, and immediately threw another coin in his hand to a higher position, and then flashed again...

Because she was not very skilled in the operation, she was a little panicked when she was in mid-air. After using three more coins, Koizumi finally stood on the roof of the 5-story building. The whole process took no more than 10 seconds.

In order to prevent the people downstairs from hearing the noise, Koizumi immediately turned into a cat after reaching the top.

Black Cat stretched her head to look at the patrol team that appeared again downstairs. After making sure that no one had noticed her little action, she withdrew her gaze with peace of mind.

Wow, it really worked. It was so exciting and fun!

Koizumi had tried to sneak into the second or third floor by flipping a coin before, but this was the first time he had done such a continuous climb.

But it turns out that her idea is completely feasible!

Theoretically, if she had enough coins, she could even flash all the way from the ground to the Tokyo Tower.

Maybe she should make a coin ejector or something, which would be easier and safer to operate.

The black cat strolled around the rooftop, trying to determine from the sounds coming from the room downstairs whether there was anyone in the house, so as to determine where to sneak in.

But it only walked half a circle before finding its target.

It wasn't that Koizumi overheard someone's secret meeting, she heard the howling of the cow cat.

[Let me out, you damned bastard! Let me out now! ]

[Damn stinky man, don't even think about touching me! ]

[Ha, now you know how powerful I am! If you want to catch me, I'll make you bleed!]

[Ahhh, don't point the gun at me! Boss, help me, Ares, help me! ]

[It’s over, it’s over, I don’t want to die! ]

[Boss, help me! ]

Just by listening to its howling, Koizumi was basically sure what was happening in the room downstairs.

Koizumi was speechless and amused.

Sheriff, you are so reckless, just keep on being reckless! Do you know how to call for help when you are in danger?

If I hadn't sneaked in in time, you might have lost your life here, you little bastard!

Although Koizumi really wanted to make the CowCat suffer, she didn't dare to waste time seeing the danger imminent.

After determining the position, Koizumi immediately took out the hook with a rope tied to it and stuck it on the roof, then grabbed the rope and jumped downstairs.

The lights in the room on the fifth floor were off and no one was there.

Continuing to descend, she then saw the situation in the room clearly through the fourth-floor window.

The cow cat was jumping up and down frantically in the room. There was a man in the room holding a gun with a furious look on his face, trying to aim at the cow cat and shoot.

Koizumi saw two deep bloody scratches on the back of his hand, which were obviously the work of the Cow Cat just now.

Koizumi reached out and pressed on the glass, and then put the glass that was blocking his path into the system space.

She was about to jump in through the window, and just as one foot stepped on the window frame, the cow cat suddenly pounced on her and shouted excitedly: "Boss, save me!"

Koizumi suddenly saw a black mass rushing towards his face and subconsciously dodged it.

The cow cat missed its target and jumped out of the window that had lost its glass, falling downstairs in a perfect parabola.

[It’s over————]

Koizumi: ...

If I wasn't afraid that this guy would make too much noise and attract the attention of the patrol team downstairs, I would really want to wait until it is about to fall to the ground before taking action, and give this little bastard an unforgettable memory.

But the timing was wrong, and she had already been discovered by the man in the house.

Koizumi immediately put the cow cat into the system space with a thought. At the same time, he steadied his body, kicked hard on the windowsill, and pounced towards the man in the room.

The man didn't expect that someone could break in from here.

The window was clearly closed and he didn't hear any sound of glass breaking, so how did someone get in?

If he hadn't seen this person when he was following the cow cat, he really wouldn't have noticed that someone had sneaked in here, and his mind was a little confused for a moment.

The surveillance and patrols downstairs were so strict, how come no one noticed him?

How did he open the window so silently without making any sound!

And if you want to sneak in, just go ahead and sneak in. Why don’t you find an empty room instead of sneaking up to me?

Now, no one is happy. It’s so annoying!

A lot of thoughts flashed through the man's mind in an instant, but he was a professional after all, and his reaction was not ambiguous at all. Even though his brain hadn't figured out what was going on, his body had already reacted automatically, and he subconsciously aimed the gun at the intruder.

At this time, Koizumi had already rushed in front of the man, and just before the man pulled the trigger, his finger lightly touched the muzzle of his gun.

Receive!

The man maintained the shooting posture and pulled the trigger several times in succession, only then he realized that his gun was gone.

The man was stunned for a moment, and while stepping back to try to distance himself from the intruder, he wanted to call for help.

But with these few seconds of buffer, Koizumi has completely taken the initiative.

Taking advantage of the moment when the man was in a panic, she flashed behind him and hit the back of his neck with the butt of the gun.

The magical law in the Detective world, "hitting the back of the neck will make you dizzy," has come into play again.

When the man fell, Koizumi reached out to support him, so there wasn't much noise.

She walked to the door and listened for a moment to make sure that no one outside noticed anything unusual in the room and that there was no other movement in the corridor.

Koizumi opened the door a crack and used a small mirror to check the situation outside.

The lights were on in the corridor, but no one was there.

Koizumi vaguely heard some chaotic talking coming from a distance, but it was obviously not coming from her level.

After closing the door gently, she walked around the room with the signal detector and found no eavesdropping devices.

After making sure it was safe, Koizumi walked back to the unconscious man, calmly took out his pistol and silencer, and gave the guy a quick death.

So, what to do next?
