"It's not that easy!" Li Xiao sighed secretly.

It seems that there are three lottery chances, and it would be good to win one reward.

"Forget it, it's all given away anyway, you can earn if you win the lottery, and you won't lose if you don't win the lottery!" Li Xiao thought about it, and immediately started the second lottery.

But watching the lottery wheel start to turn, his mood was still nervous, and he couldn't help but look at the lottery interface in front of him expectantly.

After a while, the turntable stopped, and a large gift bag pattern suddenly appeared in front of Li Xiao's eyes, Li Xiao was overjoyed, it seemed that he had won something this time.

"Dear host, congratulations on winning Godzilla Roleplay Experience Card X5 times." The sound of the system sounded.

"I'll go, Godzilla cosplay experience card?" Li Xiao's eyes widened slightly.

He could see that the meaning of this character experience card should be that he could play Godzilla for a short time.

Sure enough, the system interface in front of me appeared on the experience card usage method and introduction.

Each time you use the experience card, you can transform into Godzilla to role-play and have all Godzilla's abilities.

An experience card can be played for up to 48 hours, but after playing Godzilla with an experience card, you can choose to end the play after at least 6 hours, or wait for 48 hours to end automatically.

"I'll be obedient, this prize is a bit big!" Li Xiao exclaimed in his heart, he didn't expect to win the monster character experience card, and it was such a behemoth.

According to the introduction given by the system, this is a super behemoth that is 120 meters high, weighs nearly 100,000 tons, and has atomic breath.

If he appeared in this world as Godzilla, I am afraid that it would cause panic all over the world.

But it must be a good feeling!

After calming down a little, Li Xiao started the last lottery.

He didn't have much hope this time, after all, he was lucky to hit one out of three times.

"Dear host, congratulations on winning the science and technology gift package, graphene preparation of the whole industry technology." The sound of the system rang out again.

"I'll go, I'm hit again!" Li Xiao was pleasantly surprised.

But when he reacted to the prize he had won this time, the blood in his whole body instantly surged to the top of his head, and his heart couldn't help beating a few times.

Graphene preparation of the whole industry technology!

This prize is too powerful!

Li Xiao knows the value of this prize too well, and it can be said politely that this is a reward that can make him rich.

Although Li Xiao is not a material subject, he often likes to watch popular science and knowledge videos on weekdays, so he still knows a lot about graphene, the famous king of materials.

Graphene materials have excellent optical, electrical, and mechanical properties, which are the cornerstone of future science and technology, and are also considered to be revolutionary materials in the future.

For example, the carbon-based chips produced by it can replace the original silicon-based chips, break through the manufacturing limits and performance bottlenecks of the current silicon-based chips, and increase the performance of the chips by at least ten times, or even more than a hundred times.

Applied in the field of batteries, super batteries can be manufactured to solve the problems of slow charging speed and insufficient capacity, and truly open the era of new energy.

In addition, the mechanical strength of graphene material is 200 times that of steel, and if it is applied to fighter jets and sports cars, it can greatly reduce its weight and improve its mechanical strength.

And that's just the tip of the iceberg when graphene is used, covering almost every field of applications, including materials, microfabrication, energy, biomedicine, and drug delivery.

It can even be used as the main material for making Spider-Man's suit.

Over the past countless years, countries and countless companies have invested heavily in research in this field.

It's a pity that the research on the application of graphene is progressing rapidly.

However, the preparation of graphene has always been a problem.

At present, it is basically difficult for the existing preparation methods to achieve high quality and mass production of graphene materials, let alone be commercialized.

Therefore, if the problem of graphene preparation is completely solved and this material can be truly commercialized, then it will definitely make earth-shaking changes in the science and technology of the whole world.

It will even completely break the current world's scientific and technological pattern and open a new era of science and technology.

It can be said that whoever masters the technology of graphene mass production will master the wealth of the future.

It's as if you can produce gold and oil by yourself, and with exclusive technology, you can definitely harvest the wealth of the whole world.

It's exciting to think about.

Li Xiao knew very well that although he had gained a lot of money this time, this money was nothing in front of those really rich people.

And when there is a certain amount of money, it is just a string of numbers.

After all, people still have to realize their self-worth, be recognized by society, and have social status and reputation to be truly successful!

And graphene materials can let themselves have it all.

After Li Xiao returned home, he immediately claimed the two prizes.

At the same time, a huge amount of information was quickly integrated into his mind, all about the technology related to graphene preparation.

Not only that, but he also obtained a lot of manufacturing drawings for graphene preparation equipment.

The amount of information that was integrated into his mind this time was a bit large, and because of the time difference, Li Xiao couldn't help but fall asleep.

In the kitchen, Li Xiao's mother, Ma Dongmei, was preparing lunch.

She knew that Li Xiao was coming back today, so she deliberately got up early and went to the market to buy pork ribs and chicken wings, and prepared Li Xiao to make his favorite cola chicken wings and braised pork ribs.

"Dongmei, my son is asleep!" Li Yu's father, Li Jianye, walked into the kitchen and said softly.

"Huh? I slept, alas, I made it early, and I didn't even eat lunch! Ma Dongmei said with some self-reproach.

She forgot about the jet lag of her son, so she prepared lunch at the usual time.

"You do it first, wait until it's ready, and then tell him to get up and eat!" Li Jianye said.

"Don't call him, let him sleep, it's jet lag, I won't do it, otherwise this jingling noise will make the child sleep badly!" Ma Dongmei said.

"Huh? So what are we going to eat at noon? Li Jianye asked.

"Isn't there leftovers from last night!"

Li Jianye: "......"

Li Xiao slept directly until dark, when he opened his eyes, it was already more than seven o'clock in the evening, and he thought he was in the United States in a trance, but the smell of braised pork ribs in the air made him instantly realize that he had returned home.

He felt like he had long, long dreams in which he seemed to be a scientist and experimented again and again.

Gollum......

Sitting up from the bed, Li Xiao's stomach began to scream.

And the extra memory in my mind also instantly emerged, it is the relevant knowledge about the preparation of graphene, and even many application technologies.

The system-rewarded graphene preparation technology is a kind of bioengineering to prepare graphene, which is a very subversive method for the current world.

The approximate way is to use a bacterium called Nearchaea to prepare graphene with a monolayer of carbon atom structure.

You must know that the current mainstream are mechanical exfoliation, liquid phase exfoliation, chemical oxidation, etc., which are either difficult to mass produce, or the quality of the graphene produced is not good.

True graphene refers to a single-layer hexagonal network structure made of carbon atoms.

The graphene materials usually referred to are graphene with less than ten layers, and it is difficult to manufacture this graphene material in large quantities by the current manufacturing method, let alone a single-layer graphene material.

This shows how powerful this preparation technology is.

Moreover, the equipment of this preparation technology is not complicated, mainly the equipment for bacterial culture, which can be used with certain improvements with the existing bacterial culture equipment on the market.

The only challenge is to find and grow Nearchaea bacteria.

This is a kind of bacteria that exists in the deep sea, generally only exists in the deep sea sunken wood below 10,000 meters, and belongs to an extremely rare bacterium that has not even been discovered by humans at present.
