After all, being with Pluto, who is always holding 'Satan's wings' in his hand, is really too much pressure.

After having lunch together, Koizumi Hongko stopped staying.

Send the witch away.

Kuroba Kuidou also took the initiative to chat about the 10 million material fee. To sum up, it was because he had a bad cold after returning from Mermaid Island, and he had never been able to go to the black market to buy and sell transactions.

However, seeing the **** is still a bit conscientious, knowing that he is coming to visit him, so he also decided to help buy it as soon as his illness was cured.

"Then you can take good care of yourself."

Ye Geng nodded and came to a cool place in the corner of the room. He leaned over to observe a transparent jar placed here. After confirming that the solution inside had been completely fused, he directly opened it and took out some with his fingernails and smeared it on the palm of his left hand.

Kuroba Kaito came over curiously to watch.

In the morning, he wanted to ask, but because of Koizumi Hongzi's presence, it was inconvenient for him to discuss more about disguise, so as to 'expose' the connection between himself and the phantom thief Kidd.

But now, after seeing the effect of the solution, Kuroba Kaito finally couldn't help but ask:

"Eh? Brother, this thing looks good, you're new to research?"

"It's just that the proportion of the materials has been modified. It's not a new study." Ye Gengyi said.

"I'll try too..."

Kuroba Kaito also plucked a fingernail and smeared it on his finger.

After a few seconds.

"Good thing! If you don't touch it carefully, you may not even be able to feel its existence. It has good flexibility and good air permeability. Hehe, brother..."

Kuroba Kaito showed a "you know" expression.

"Wear the mask and prepare two more materials, I will teach you." Ye Gengyi said.

"Okay!" Kuroba quickly ran to the secret room to get something.

a little while.

The coffee pots and tea cups on the coffee table were missing, and were replaced by a dozen large and small bottles and jars.

Ye Geng confirmed the labels and arranged them in the order in which they were prepared.

Since this time, I need to explain the deployment process and which data model to apply, so Ye Gengyi deliberately slowed down the action, and after confirming that the proportion of the materials in the Black Feather Quick Bucket is normal, the next step will be explained.

Hey, do you even have to master the number and strength of shaking?

Kuroba Kuito muttered silently in his heart, but there was no mistake in the movements of his hands.

Often, as soon as Ye Geng has finished explaining the principles and performing the demonstration actions, he can repeat the same as the general subject.

Teaching went well.

In this way, for about an hour or so, two jars filled with the 'new' model disguising liquid were placed in the shadow of the corner.

"Wait about two more hours and it's ready to use."

As soon as Ye Geng said that, he picked up the pen and paper on the side and wrote with a 'swish'.

After writing the pen, he confirmed that the steps were all right from the beginning to the end, and then handed it to Kuroba Kuito, saying:

"For the sake of your fever, maybe your brain isn't enough, you learn to destroy it again."

"Hey... look down on someone."

Kuroba Kuito took it, folded it, and put it in his pocket.

At this time, he also felt a lot.

Originally, he thought he had inherited his father's disguise, and he was quite proficient in the materials and masks used for disguise.

As a result, after listening to Ye Gengyi's explanation, Kuroba Kuaidou realized that he really only knew it but didn't know why.

When making props, why do you use those kinds of materials in a fixed link, and how the materials have changed during this period of time? The details of this one after another may seem cumbersome, but after mastering it, you may be able to use it in Maybe it will work wonders against such opponents in the future.

"Hey, by the way, brother, since you are here, you are helping me see this."

Kuroba Kaito trotted back to the bedroom again, and walked out with his laptop in a while.

After he turned it on, he opened a document and handed it to Ye Genyi to check it out.

"It's... a smoke bomb."

"right."

Kuroba Kuito nodded, "The availability of other props from that old man A Li didn't say, it is this smoke bomb. Sometimes when it is used outdoors, it is dissipated too quickly by the wind. I tried to improve it. The amount of medicine in it has been increased, but the effect is sometimes not very satisfactory."

"Your thinking is limited by numbers..."

Ye Gengyi quickly read the document and understood Kuroba Kuito's idea.

He explained while making revisions:

"With the existing technology and cost, blindly pursuing the compressed charge, it is necessary to improve the ignition and detonation device. It is better to change the way of thinking... Well, how about this change?"

"Use two smoke bombs at a time to replace the ingredients in the smoke generator, let the two detonate and fuse in the air, and then generate a larger smoke range?" Kuroba Kaito's eyes lit up.

"I use this method all the time, like..."

As soon as Ye Geng said, he also took out two **** and placed them on the table, giving an example:

"One of them will continuously release dust after detonation, covering a range of about 10 meters in diameter. Although its concealment is average, when combined with incendiary bombs, it will explode in an instant. It is smaller than the traditional grenade, and its lethality is slightly stronger. ."

"This is a little dangerous..." Hei Yu was about to sweat.

Murder or something, hypnotic gas, flash bombs, and smoke bombs are fine...

"Just to give you ideas." Ye Geng said with disapproval.

He didn't want these things to be used frequently, but if he really used them, he wouldn't have any psychological burden at that time.

"I just want the kind of smoke bomb that can form a large area of ​​​​blocking effect when the two are detonated together." Kuroba said.

"Oh, UU reading www.uukanshu.com go back and research it for you."

Ye Geng nodded and said: "When I have an idea, I will send you the formula and ratio directly. I understand the reaction relationship inside, and we can study new ones together in the future."

Kuroba Kuito suddenly felt that someone's 'scientific certificate' might have been violated again. He recalled that when he was studying the repair effect of nano-robots, he was 'under house arrest' at home, and his arm was constantly knocked off. Chilled, he hurriedly sent a basin of cold water and said:

"No need... Brother, I'm only in high school."

"Sooner or later, I have to learn." Ye Geng said calmly.

"Cough... Then I'll learn slowly first, and ask you when there is something I don't understand."

Kuroba Kuito pondered his words, trying to push this matter forward as much as possible.

"Oh, that sort of thing is up to you."

To Hei Yu Kuaidou's surprise, Ye Geng just nodded, a rare look of exhaustion appeared on his face:

"I'm a little sleepy, take a break."
