"What? Are you sure?" Chen Pengxin directly ignored Liu Tian's arrogant look, his voice octave: "You kid are you not fooling me?"

"I'll fool you, I have food to eat." Liu Tian was so angry that he directly retorted.

"Really? Confirm?" Chen Pengxin's voice became serious.

"Yes, really, I'm invisible in sight. What I did in the morning? Are you interested?" Liu Tian smiled and diaoyan.

"How could it be that I wasn't interested? Are you in your lab now?"

"Um."

"You are waiting in the laboratory, I'll go over immediately. If you have any questions, we'll talk about it later." After confirming that Liu Tian was not a joke, Chen Pengxin couldn't sit still at this time.

"Are you always here in person?" Liu Tian curled his lips and said, "Just arrange someone you can trust to come and take it away."

"Okay, I'll hang up first, let's meet later." Chen Pengxin ignored Liu Tian and hung up the phone directly, rushed to Jiangdong Industrial Park.

“…”

One hour later;

Liu Tian, ​​who was doing the experiment, received a call from Chen Pengxin.

"Old Chen, are you here?" Liu Tian glanced at the raw materials that were still reacting, and connected the phone that was constantly refreshing its presence.

"For me outside the gate of your experimental area, come down and take me in."

"You just call the guards and I'll ask them to take you in. I'm still doing experiments and can't leave for a while. Please wait outside for a while." Liu Tian said as he aimed at the instrument.

"OK!"

“…”

Half an hour later;

After completing the experiment, Liu Tian went downstairs and brought Chen Pengxin into the laboratory.

"Your kid's laboratory is good." Chen Pengxin looked at the very high-end experimental equipment in the laboratory and sighed: "It took a lot of money."

"It's okay." Liu Tian said with a normal face: "It's not much money, it seems that this material laboratory is 4.5 billion."

"Uh..." Chen Pengxin swallowed and said, "You guy is rich, but one laboratory equipment is only billions."

"The material is here." Liu Tian pointed at the table, a 15KG capacity glass bottle.

"This is the invisible material you just mentioned." Chen Pengxin stretched his neck curiously and looked at the translucent material in the bottle.

"Yes, but the shortcomings are obvious." Liu Tian nodded.

“???”

"You can only see invisible, and you can do nothing to radar and ultrasonic devices." Liu Tian explained, and there is also a limitation on the use time.

"I can't see it at all with the naked eye?"

"Yes, I can't see it at all." Liu Tian directly pulled two A4 sheets from the table: "This is the test report and instructions for use. You can take a look first, and you will talk about anything you don't understand."

"Yes!" Chen Pengxin took the A4 paper directly.

“…”

"The cost is very high." Chen Pengxin said after reading the test report.

"It's a bit high. This small bottle uses about 500,000 yuan of raw materials." Liu Tian pointed to the glass bottle and said.

"Your materials cannot be leaked out of the market or published to the public, otherwise it may cause panic." Chen Pengxin said seriously: "It can only be used in a specific environment, and it cannot be known that this is invented by you, otherwise no one knows what will happen."

"I understand, so I'm calling you here all the time." Liu Tian spread his hands helplessly.

"Can you sell the recipe to us? After all, you can't use it." Chen Pengxin thought for a while, then asked, "Don't worry... you can ask any conditions and we will satisfy them as much as possible."

"I thought about it, discuss it with my wife tonight, and then reply to you, how about it."

"Okay, then I'll take these back for testing." Chen Pengxin pointed to the glass bottle on the table.

"right."

"Then I'll take it away now. After you discuss it, let me know as soon as possible."

"Do you want to have supper before leaving?"

"I'm not in the mood to have a meal now. I'll treat you to the test." Chen Pengxin said and picked up the bottle.

"Okay, then be careful, it's quite heavy."

"You bring the test report and instructions back."

"Please help me take the stairs."

“…”

night:

Liu Tian raised Chen Pengxin's request to Yan Yuyan.

"They can understand the formula. After all, invisible materials can be said to be included in the highest level of strategic materials. If we ask us to help produce them, they may not be relieved." Yan Yuyan explained.

"You mean to sell it to him?" Liu Tian asked.

"You can't sell it, but you can authorize it." Yan Yuyan shook her head directly: "Although I know I can't use it basically, what if I use it in the future?"

"Then what conditions do you want?" Liu Tian asked curiously.

"We don't lack anything. The things we lack may not help us get back." Yan Yuyan said helplessly: "For example, some high-end experimental equipment should you just need cash."

"That's fine. Anyway, we will help us if we have difficulties in the future." Liu Tian was too lazy to agree directly: "How much does it cost to sell?"

"Let them offer the price." Yan Yuyan blinked.

"Okay, give them a headache."

“…”

The western suburbs of the imperial capital;

A highly confidential study.

Invisible material is being tested.

Chen Pengxin looked at the moment when the power was turned on, the tank model that was originally in front of him disappeared directly from under him.

Even if you are mentally prepared, but...

My heartbeat jumped from one hundred to one hundred and eight.

...

Half an hour later, the test ended.

"The effect is very good, but the disadvantages are very obvious." An old man with a gray hair on his head said to Chen Pengxin: "According to the conclusion just obtained from the experiment, he can only work for ten hours at most, and then he will be useless."

"You mean, is this a disposable product?"

"Yes, but you can stop in the middle, just one power supply." The old man said excitedly: "Old Chen, the amount is too small. Is there any? I want to get a fighter plane to try the effect."

"That's all for you."

“…”

More than ten minutes later, Chen Pengxin left the institute with a video with a test report.

One hour later:

Cabinet meeting.

"Can you buy the formula?" Jiang Tao asked quickly after watching the video and the experimental report.

"I didn't agree, nor did I object." Chen Pengxin shook his head.

"Ask Xiao Liu what conditions are there and try to meet them as much as possible. For us, this material is a big killer weapon." Jiang Tao said seriously: "It's a useless rib in his hands."

"Yes, there are not many places he can use." Yang Shan made a fuss.

"Communicate, think of a way."

"He said he would discuss with his wife before notifying me, but there is no reply yet." Chen Pengxin waved his hand.

"Wait, but I don't think the problem is big."

“….”

"No one knows it was developed by Xiao Liu, right?" Jiang Tao changed the subject.

"Don't worry, now only a few of us know." Chen Pengxin added: "Even the research room doesn't know."

"That's good, this matter cannot be spread."

“…”

"Ring, ring, ring..." At this time, a cell phone ringtone rang in the conference room.

"?"

"???" The few people instantly calmed down and their eyes gathered on Chen Pengxin.
