In the following days, Lin Xuan once again devoted himself to his work, spending most of his time in the company every day, leading the two major technical teams of Xuanyu Intelligence and Xuanyu Technology to complete the development of the computer version of the intelligent voice butler and several foreign language versions of the intelligent voice butler.

Working overtime and staying up late has become their daily routine, and Lin Xuan doesn't even have much time to spend with his mother and girlfriend.

After nearly 20 days of hard work, Lin Xuan finally led the team to complete the development of several foreign language versions of the intelligent voice butler, such as English, Korean, Japanese, French, German, and Russian.

The core module of the computer version of the intelligent voice butler, as well as various functional modules, are also basically completed, and Lin Xuan is expected to be completely completed on the eve of spring.

This software, Lin Xuan named it "Intelligent Security Master", its general function is similar to that of the intelligent voice butler APP, but on this basis, Lin Xuan has improved the facial recognition and gesture recognition engine, which can identify some facial expressions and simple gestures of the user by controlling the computer camera, which can be regarded as the first step in human-computer interaction.

Not only that, Lin Xuan also focused on the development of functional modules in information security, by replacing part of the operating system source code, and even the kernel program, so that the system performance has been improved, and at the same time, an independent firewall is added to the outer layer of the entire system program.

This is equivalent to adding a wall to the outside of the system that originally left the back door, and then re-opening a new gate, which will automatically encrypt the information in and out, so as to realize the blocking of the back door of the system, the guarantee of information security, and the encryption algorithm used is also uncrackable by the current computer technology.

Therefore, Lin Xuan is confident that as long as this software is installed, it will definitely be able to ensure the information security of all computers at present.

After these 20 days of precipitation, the paying users of the intelligent voice butler have basically stabilized at the number of 180.6 million, but there will still be a dozen increases every day.

As for the graphene preparation equipment that Lin Xuan talked to Chen Yu before, Chen Yu has also found different foundries according to Lin Xuan's requirements, and according to some information provided by Lin Xuan, he has produced several different mechanical components that make up the final equipment.

Now it has been placed in a warehouse temporarily rented by Lin Xuan, waiting for Lin Xuan's final assembly and experiment.

Of course, the reason why Lin Xuan found different foundries to customize different parts at the same time, and also had to assemble them himself, was also to prevent technology leakage.

On this day, after completing the performance test of several foreign language versions of the intelligent voice butler, Lin Xuan drove Chen Yu to the warehouse he rented.

"It seems that assembling this equipment is also quite a project!" Looking at the large machine parts placed on the floor of the warehouse, Lin Xuan had a headache, and secretly said that if he had a mechanical arm from the "Iron Man" movie, Du Man, it would be good to be an assistant.

"Third child, do you want someone to come over and help assemble it!" Chen Yu opened his mouth and said.

"No, I just don't want to be known about the principle and structure of this equipment, so I didn't let the foundry directly produce the finished product, but then I have to work hard for you to help me!" Lin Xuan said with a wry smile.

Chen Yu looked at the huge mechanical components, and the corners of his mouth twitched, it seemed that he was going to work hard for the past two days.

"Okay!" Chen Yu said helplessly.

The production equipment that Lin Xuan wants to assemble is actually not complicated, and the precise and complex parts, he has already asked the foundry to do a good job, and he only needs to manually assemble and splice several large components of the equipment.

But despite this, Lin Xuan, with the help of Chen Yu, also installed it for nearly two days before finally assembling the entire equipment.

Looking at the equipment in front of him that didn't seem to be much different from ordinary CNC machine tools, Lin Xuan nodded with satisfaction, now that the equipment is assembled, the next step is to carry out processing tests!

With a hint of anticipation and nervousness, Lin Xuan took the graphite crystals that Chen Yu had helped prepare early in the morning and put them into the raw material into the hatch, and connected the liquid nitrogen storage tank to the refrigeration system of the equipment.

Immediately, after some debugging and setting on the control panel, the hatch was closed and the start button was pressed.

After the equipment was running, it didn't make too much noise, and soon the completion indicator light of the equipment lit up, Lin Xuan immediately opened the discharge hatch, casually pulled out a transparent film from it, pinched it with two fingers, and brought it to Chen Yu.

"See, this is graphene material!" Lin Xuan said with a happy face.

Chen Yu took a closer look, the film was very thin, and if you didn't look carefully, you wouldn't even be able to see its existence.

"The thickness of the single layer of graphene is only 0.335 nanometers, and the 200,000 pieces of film are superimposed together, which is only as thick as a human hair, and its light transmission is also very good. The ones I hold in my hand are estimated to be thousands or even tens of thousands of graphene! Lin Xuan spoke again.

"This is graphene, it's incredible, it's so easy to prepare, this preparation technology is too awesome!" After a short period of consternation, Chen Yu couldn't help but show an excited look on his face.

He knows very well that materials and energy are the two most profitable industries, because he is related to all aspects of the entire basic industry, and at this stage he also deliberately consulted a lot of information about graphene, thoroughly understood the huge impact of graphene on the entire industrial science and technology, and also knew the value of this new material.

As a new type of nanomaterial, graphene has the advantages of extremely high mechanical strength, good electrical and thermal conductivity, specific surface area, very good chemical stability, etc., and can be applied to many fields such as electronics, information, energy, materials, catalysis and biomedicine.

It can be said politely that the mass production of graphene will definitely cause a scientific and technological change, or even change an era, and the various products derived from it are also promising.

It's a pity that so far, countries around the world have spent huge sums of money on research and development of graphene preparation, but there has been no good way.

And now, their Huaxia, no, to be precise, their company, has mastered the preparation technology of graphene, so will their company be short of money in the future?

Not to mention the continued production of graphene composite materials or derivative products, just selling graphene materials is definitely like printing money.

At that time, I am afraid that even my father will take the initiative to find his own company to buy materials, and he will finally be able to stand up in front of that family in the future.

It's cool to think about!

"Third child, I'll go to the government to buy land and build a factory in the next few days!" Chen Yu said excitedly.

"Don't need it yet, boss, I'll change my attention temporarily!" Lin Xuan waved his hand and said.

"What do you mean?" Chen Yu's face froze, and he looked at Lin Xuan in surprise.

"I want to wait for the intelligent security master to finish, and directly tell Director Wang about graphene, so that he can breathe through it!" Lin Xuan said in a deep voice.

"Are you going to work with the government?" Chen Yu immediately guessed Lin Xuan's intentions, and his face sank slightly, "Then our graphene may have to be banned from export!" ”

Chen Yu knows very well that if exports are banned, then although they can also make a lot of money, after all, the domestic market is still limited, and the foreign market is infinite.

"Alas—even if we don't cooperate with the government, they will ban it, and it won't be a matter of official paper when the time comes!"

"Well, too!" Chen Yu also thought of this, and nodded slightly, no matter which country has to keep high-tech materials strictly secret, let alone graphene, the king of materials of great significance to national defense.
