Zhang Li naturally couldn't eat 13 tons of graphene.

Of course, he didn't believe that Regis had so much graphene.

For more than ten years, the amount of graphene produced in the world has been less than one ton. Your 13 tons is also beautiful. It is okay to deceive children, but adults know that it is impossible.

"Okay." Jian Pengfei chuckled softly, instead of forcibly explaining, he changed the topic: "President Zhang, please tell me in detail, how much graphene is needed."

Zhang Li thought for a while and reported a number: "1 kilogram, is there?"

"have."

“Where is the price?”

"3,000 yuan per gram, 3 million per kilogram."

"You ask me to discuss it and then give you a reply, okay?"

"no problem."

After hanging up the phone, Zhang Li looked at Meng Nanfeng next to him and said, "Academician Meng, the other party said that there is 1 kilogram of graphene. The price is 3,000 yuan per gram. What do you think?"

Meng Nanfeng thought for a while and replied: "In terms of price, it is a little bit more expensive. The price of kilogram single crystal wafers will not exceed 2,000 yuan per gram.

However, this is a price of less than 4 inches, and a size of 1 meter, which is naturally another offer.

In addition to loss, a single-layer graphene of 1 kilogram can be used to make about 1 million double-layer graphene. The strength and hardness of double-layer graphene rank first in the material industry, and the stiffness is also very good.

In other words, after this size of double-layer graphene is modified and isolated and covered with multiple layers, it can be made into at least 10,000 sets of world-class nano-body armor or bulletproof glass, which cannot even penetrate large-caliber sniper rifles. One set is sold for tens of thousands of yuan. In some war-torn areas in Africa and the West, it can be said that it is in short supply.

Of course, in addition to making top-notch nano-bullet-proof products, it can also make many other products, but no matter what, if it is done well, the derivative value of this kilogram of single-layer graphene can exceed 100 million yuan, so you can buy it.”

Zhang Li's eyes flashed slightly: "In other words, I'll make sure to make a profit if I spend three million yuan, right?"

Meng Nanfeng nodded: "You can think so, but you must be careful that this is a scam from Regis. Judging from the current technological height, no company in the world can achieve this output. There are too many single-layer graphene in 1 kilogram of 1 meter-level…"

Zhang Li touched his chin and said, "Preventing scams is simple. When delivering, we can just move the instruments over to inspect them. Isn't that okay?"

"Uh..." Meng Nanfeng was stunned and smiled bitterly: "That would probably take a lot of time."

"No need to complete all the tests, just randomly draw them. As long as there is no problem with the randomly drawn data, there is basically no big problem."

“That’s right.”

After agreeing on the plan, Zhang Li called Jian Pengfei back and finalized the plan.

A single layer of graphene with a specific surface area of ​​2630㎡/g, totaling 3 million yuan!

In addition, since real gold is not afraid of fire refining, when Zhang Li proposed to set the trading location, Jian Pengfei agreed without hesitation.

Therefore, at 2:30 in the afternoon, Jian Pengfei took a key from Jiang Bo, went to Wuchen Warehouse to get a kilogram of graphene, and then took people to the carbon nanoengineering laboratory invested by Keyuan Company.

Of course, there is not much graphene, but with the base material and sealing material, it is more than 100 kilograms.

Under the transportation of two St. Regis employees, a yellow sealed container containing graphene was moved to the laboratory trading location.

Jian Pengfei pointed to the container and smiled: "Mr. Zhang, 1 kilogram of graphene, yes, it's all here. You can unbox and inspect the goods, but I would like to remind you that it is best to choose a dust-free area for unboxing."

"Okay, then please wait for Mr. Jian. I'll have someone go to inspect the goods." Zhang Li nodded, turned around and said a few words to Meng Nanfeng, and then asked several laboratory personnel to carry the container into the testing center.

Soon, under the leadership of Meng Nanfeng, the staff in the entire laboratory stopped their work and began to randomly draw and test the graphene in the container.

Jian Pengfei followed Zhang Li to the reception room for tea.

Time passes by minute by minute.

More than an hour later, Meng Nanfeng came to the reception room with a copy of information and looked disbelief.

"Academician Meng, what is the test result?" Zhang Li quickly stood up and asked.

Meng Nanfeng shook his head with a serious expression: "No..."

"No?" Zhang Li frowned when he heard this, but Meng Nanfeng's words caught him off guard and shocked him.

"Mr. Jian, the size of the graphene single crystal wafer you gave does not match what was stated in advance. The size of 10mx10m, how can this be? How did you make it?"

Meng Nanfeng had red eyes, staring at Jian Pengfei like a long-awaited tiger.

Jian Pengfei put down his legs and crossed his legs, smiled and said, "I mean, this is a graphene wafer of 10 meters and a hundred square meters. Are you still not satisfied with it?"

"10-meter-level graphene?" Zhang Li was confused when he heard it: "No, Academician Meng, what's going on?"

Meng Nanfeng took two deep breaths and replied in a deep voice: "The batch of graphene just now is not 1 meter level, but 10 meters level. Each piece has an area of ​​100 square meters..."

"This...100 square meters of graphene? This...is impossible!" Zhang Li denied it without thinking.

Meng Nanfeng said: "Before I had tested it, I didn't believe that there were graphenes of this size in the world, but when we randomly cut 100 randomly selected graphenes, we then tested them.

The results obtained are exactly the same as the data of the two previous standard single-layer graphene.”

Zhang Li frowned, still unable to believe it. After thinking for a long time, he finally thought of a key: "Can it be that the detection instrument has a bug?"

However, after saying this, Zhang Li found that Meng Nanfeng looked at him like a fool, and knew that he had said the wrong thing.

Meng Nanfeng shook his head and said, "It's not a problem with the instruments. There is no problem with the instruments. Moreover, more than a dozen instruments cannot all fail."

"But how is this possible? A 10-meter-level graphene film..." Zhang Li looked at Jian Pengfei with an exaggerated expression: "Mr. Jian, how did you do it? It is impossible for a company to make graphene of this size!"

Jian Pengfei had already thought of the words and said lightly: "How did it be created? Actually, I don't know. And even if you know, do you two think I will tell you such a commercial secret?

Okay, since the inspection has shown that there is no problem, then Mr. Zhang, why would you call me the remaining amount?"

Zhang Li glanced at Meng Nanfeng, saw the latter nodding slightly, and suppressed many emotions in his heart and said with a smile: "I'll call you to transfer the money to you. Don't worry, everyone is a well-known businessman and will not be able to pay any debts."
