After all, Pluto, who was holding the "Satan wing feathers" in his hand at the moment, was a piece of pressure. The pressure was too big.

After lunch together, Koizumi Hongzi stopped staying.

Get away from this witch.

Hei Yu's fast fight also took the initiative to talk about the material fee of 10 million. In summary, it was because he had a cold after returning from Mermaid Island, and he could not go to the black market for trading.

However, looking at the mixed brother is a bit conscience, knowing to visit himself, so he also decided to wait for the disease to buy it.

"Then you will take good care."

Ye Gengye first, came to the cool position in the corner of the room, leaned over to observe a transparent jar here, confirmed that the solution inside was completely fused, and directly opened it with nails and removed some of the palms of the left hand.

Black Yu quickly came over and watched curiously.

In the morning, he wanted to ask, but because of Koizumi Red Son, he was not convenient to discuss things about Yirong's camouflage, so that he could ‘expose’ out the connection between himself and the strange thief Kidd.

But now, after seeing the effect of the solution, the black feather fast fight finally can't help asking:

"Well? Brother, this thing looks good, do you have a new research?"

"Just modify the proportion of materials for the material, it is not a new study." Ye Geng said.

"I try ..."

The black feathers also picked a nail cover and wiped it on the fingers.

A few seconds later.

"Good things! If you don't touch it carefully, you may not even feel its existence.

Hei Yu quickly revealed a expression of ‘you know’.

"Wear the mask and prepare two materials, I teach you." Ye Geng said.

"Okay!" Hei Yu's fast -fighting movement ran to the secret room to get things.

Slightly.

The coffee pots and tea cups on the coffee table are not seen, and they are replaced with more than a dozen large and small bottles and cans.

Ye Geng confirmed the label, and arranged in order in order of the sequential order of the deployment.

Because this time it is necessary to explain the process of deployment and which data model is applied, Ye Geng deliberately slowed the movement and confirmed that the proportion of the material in the black feather fast bucket tank was normal, and then the next link explained.

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

Hei Yu said silently in his heart, but the movement on his hand did not make a mistake.

Often, Ye Geng finishes the principle of finishing the principle. After the demonstration action is done, he can copy the entire science repeat.

Teaching is very smooth.

In this way, about an hour, two jars filled with 'new' models, were placed in the shadow of the corner.

"It's almost two hours before you can use it."

Ye Geng said, picked up the paper pen and pen, and wrote it.

After the pen, he confirmed that there was no problem with the steps from beginning to end, and then handed it to the black feather fast fight, saying:

"Look at your fever that may not have enough brains, learn to destroy it again."

"Well ... who look down on."

Black Yu took it quickly, and then stacked into the pocket.

At this time, he feels a lot.

Originally, he thought that after inheriting his dad's Yirong, he was quite proficient in the materials and masks used during disguise.

As a result, after listening to Ye Geyi's explanation, Hei Yu quickly found that he really only knew it but did not know why.

When making props, why do you need to use those materials in a fixed link and how the materials have changed during this period of time?

Maybe in the future, this kind of opponent will play wonders.

"Hey, right, since I am here, you are helping me see this."

Hei Yu quickly ran back to the bedroom, and soon took his own laptop and walked out.

After he turned on, he opened a document and handed it to Ye Geng as let him check it.

"This is ... smoke bomb."

"right."

Hei Yu quickly nodded, "The availability of the other props of the old man, that is, this is the smoke bomb. Sometimes when used outdoors, it was dissipated by the wind too fast. I tried to improve it.

Add the amount of medication inside, but sometimes the effect is still not very satisfactory. "

"Your thinking is limited ..."

Ye Geng read the document quickly, and also understood the idea of ​​Black Yu's fast fighting.

While explaining, he modified it:

"With the existing technology and cost, and blindly pursuing the amount of compression drugs, you need to improve the ignition and detonation device.

"One time with two smoke bombs, replace the ingredients in the hair cigarette, let the two blend in the air, and then produce a larger smoke range?" Black Yu quickly lit up.

"I have always used this method, such as ..."

Ye Gi said that he also found two balls and put it on the table. For example, it explained:

"One of the detonation will continue to release the dust, covering a range of about 10 meters in diameter. Although its concealment is average, it will explode instantly than the volume of the traditional grenade with traditional grenade, slightly stronger killing.

. ""

"This is a bit dangerous ..." Hei Yu sweat quickly.

It ’s still avoided, hypnotic gas, flash bomb, and smoke bombs are good ...

"Just provide you with ideas." Ye said unsteadyly.

He doesn't want to have that kind of frequent need to use these things, but if you really need to use it, there will be no psychological burden at that time.

"I want the two kinds of two to detonate together, and the smoke bombs that can form a large area of ​​blocking effect can be formed outdoors." Hei Yu said.

"Oh, look back for you to study."

Ye Gengyi first: "When I have ideas, I will send you the formula and proportion directly. I understand the reaction relationship inside. I can study the new one together in the future."

Black Yu Xun Dou suddenly felt that someone's "scientific research certificate" might be committed again. I recalled the picture of being settled by the old brother "under house arrest" when he was renovated in order to study the repair effect of nano robots.

Trend, hurry to send a pot of cold water, Tao:

"No need ... Brother, I just study in high school."

"One day in the morning and evening, I have to learn." Ye was calm in a word.

"Oh ... then I learn slowly first, and ask you when I don’t understand."

Hei Yu quickly talked to her words, trying to push this matter as much as possible.

"Oh, decide that kind of thing yourself."

It was unexpected that the black feather was quickly, Ye even nodded, and a rare tiredness appeared on his face:
Chapter completed!
