"Boss, I suggest you do a physical examination. After all, you often have nosebleeds for two consecutive months, which may be a sign of leukemia..."

Reminiscing that Chen Chen had experienced this situation in two months, Qian Wenhuan looked worried, "You are only 22 years old this year, and you have a lot of time to squander. Don't overwork, after all, you have made such a blockbuster movie. Jiangshan, if you fall, Jiangshan will give you a hand..."

　　 "Don't worry, haven't I just had a blood test some time ago?"

　　 Chen Chen waved his hand, "I'm just angry, it's okay."

"Ok……"

　　 Seeing this, Qian Wenhuan nodded, and then took out the iron box, "This is what you want."

　　 "Is it functionalized graphene obtained through oxidation?" Chen Chen asked.

"seems like it……"

Qian Wenhuan scratched his head. "I heard from Professor Farah that this thing is harder and tougher than ordinary graphene sheets. However, in order to maintain this strength and toughness, Professor Farah used this kind of graphene Stacked to the 100th floor, he said that this thing is very dangerous and should be used with care."

　　 "100-layer functionalized graphene?"

　　 Chen Chen nodded, and reached out to take the iron box road, "Also, it's almost enough."

After 　　 sent Qian Wenhuan away, Chen Chen locked the door of the laboratory again.

　　 As the opening date of the Life Science City approaches, Qian Wenhuan is very busy preparing for the opening ceremony of the Life Science City, but even so, Qian Wenhuan personally comes every time no matter what Chen Chen orders.

　　 This is also a kind of heart.

　　 Chen Chen shook his head. It seems that I can compensate Qian Wenhuan for promotion in the future.

　　 But after another thought, Qian Wenhuan was already the general manager of the African region, and there was no way for him to rise, so he gave up the idea of ​​compensating Qian Wenhuan.

　　 Thinking of this, Chen Chen took out the iron box and opened it gently. Suddenly, slices of almost transparent sheets appeared in the iron box.

　　 Graphene is extremely light-transmissive. Although there are many layers on top of each other at this time, it is like glass, and the light passes through the bottom of the box.

　　 As for Qian Wenhuan said that this thing is dangerous, this is really the case.

　　 After all, what is graphene? It is basically a layer of carbon atoms. A layer of carbon atoms is called a layer of graphene, and the thickness of a single carbon atom is only 0.34 nanometers.

　　 At this time, in Chen Chen's hands, there is a 100-layer structure of graphene, which is 34 nanometers thick and only one-two thousandths of the thickness of a hair.

　　Moreover, the graphene layer has been specially oxidized, which means that the edges of this material will be very sharp.

　　 The serrations on the edge of the graphene can easily pierce the cell membrane of the human body and penetrate into the human body. It is extremely lethal to humans and other animals.

　　 Graphene was first separated from graphite by two physicists at the University of Manchester in Europe: Andrei Gaim and Konstantin Novoselov.

　　The two also won the 2010 Nobel Prize in Physics.

　　 Since then, graphene has been added to the physics community. It is a two-dimensional crystal, the strongest substance known to mankind, and it is harder than diamond.

　　 It is not only the thinnest material, but also the strongest material. Its breaking strength is even more than 200 times stronger than steel.

A laboratory in North America once did an experiment. Before graphene particles begin to fragment, they can withstand a pressure of about 2.9 microN per 100 nanometers, which is equivalent to applying a pressure of 55N to make 1 The meter-long graphene breaks.

　　 If this graphene material is made into the thickness of ordinary food plastic packaging bags, then a pressure of 20,000N is required to tear the packaging bags.

　　 In other words, if graphene is used to make a packaging bag, it can withstand about two tons of items.

　　 And at this time, how powerful should the graphene sheet with a hundred-layer structure in Chen Chen's hand be?

　　 Thinking of this, Chen Chen's heart moved, and a thin to almost transparent sheet floated from the box. Chen Chen looked intently, but saw that the sheet was about the size of a playing card.

　　 But unlike playing cards, this sheet is almost completely transparent, and if he is not paying special attention, he can hardly find the existence of this sheet.

　　 It’s just that although this graphene is very thin, it is very tough, not much different from playing cards. Chen Chen thought about it, and simply picked up a book, opened it from the middle, and placed it on the table.

　　 Then, Chen Chen controlled the graphene in front of him and used a poker technique to exert his strength. Immediately, the graphene flakes in front of him flew out silently.

　　唰!

　　 There was a tearing sound that was almost inaudible, and Chen Chen looked intently, only to find that the middle pages of the book were directly cut off!

　　 Chen Chen picked up the book carefully, but saw that the center of the book was crossed by a gap of ten centimeters long and transparent.

　　 The cut surface of the gap is even smoother, as if books are born like this...

　　 This is an atomic attack.

　　 Chen Chen looked back in the direction of the book, only to see a pen holder behind the book, and the thin graphene layer was embedded in the pen holder, revealing only a small part of the outside.

　　This power...

　　 Chen Chen was secretly, if he used this method to attack a person~lightnovelpub.net~ what would be the result? I'm afraid that even if that person is dead, he doesn't know how he died.

　　 And because it’s too thin, I don’t even feel pain. At most, I feel a little itchy in my neck, and then I stretch my hand to scratch it, and the adhesion of flesh and blood is completely ineffective, and the whole head falls off with a crack...

　　 Chen Chen didn't touch it with his hands, but continued to take out the graphene sheet with the force of the "field", only to see that a corner of the graphene sheet had completely broken apart.

　　 Seeing this scene, Chen Chen also confirmed one thing.

　　In other words, although 100-layer graphene sheets can cut objects with lower strength, they still cannot cut objects with higher hardness.

　　 is still too thin after all.

　　To achieve the level of cutting metal, unless it is several hundred times thicker, the thickness of the blade is about the same.

　　 Although it is impossible to cut metal, this power is enough to satisfy Chen Chen.

　　 Thinking of this, Chen Chen once again pointed the "field" at the iron box and brought out all the graphene sheets inside. Only then did he find that there were a hundred graphene "playing cards" inside.

　　 nodded, Chen Chen took back the graphene sheets and put them in the iron box.

　　 These graphene flakes are too lethal. If you hold them with your hands, you can easily injure yourself, and because they are too thin, they will break easily when you apply force. Apart from Chen Chen, no one can use this kind of thing as a weapon.

　　 Just when Chen Chen just finished his experiment, Xiao X reminded again, "My Godfather, there has just been a message from the Meyer Shipyard in Germany that your customized Black Light cruise ship has been built and is ready for acceptance!"
