Chen Chen used an electron microscope to analyze the powder after the black crystals were smashed.

The result was not surprising, as there were only countless broken sheets of single-layer carbon atoms in the powder, and nothing else.

In other words, the black crystal is just a man-made diamond made of countless single-layer graphene materials.

Of course, although the material that makes up black crystals is the same as diamonds, the value contained in them is far from being comparable to that of diamonds.

The so-called graphene material is actually ordinary graphite, but it is much thinner than graphite, composed of a layer of hexagonal honeycomb structure with periodically tightly packed carbon atoms.

It was discovered by the University of Manchester in 2004, and graphene materials have excellent optical, electrical, and mechanical properties, and are considered to be a revolutionary material in the future.

About one millimeter of graphite can peel off 3 million layers of graphene.

Single-layer graphene, on the other hand, means that it has one atomic layer, and because it is so thin that it is only the thickness of one layer of atoms, many people think that it is completely two-dimensional.

Therefore, the black crystal is actually made of tens of millions of layers of graphene stacked layer by layer, and then through each layer etched into the circuit, and finally forms hundreds of billions of transistor structures.

Due to the stability of graphene, transistors can work stably at the scale close to a single atom, and the efficiency is much higher than that of ordinary transistors, and the computing efficiency of graphene processors in the same volume is millions of times that of modern computer processors.

And because graphene is flexible, biocompatible, and conductive at the same time, it can be used as an excellent neural interface electrode, and graphene electrodes will be more stable in vivo than tungsten or silicon electrodes.

However, in this case, if you want to modify the chip, it is not a conventional way to do it.

Chen Chen thought for a moment, turned off the signal shielding device, and at the same time turned on his mobile phone to make a call.

……

Half a month later, Chen Chen looked at a huge data center in front of him and shook hands with a blonde man with satisfaction.

"Congratulations, Mr. Chen, you will be the owner of this data center from now on."

The blonde man held Chen Chen heavily and smiled heartily.

"Thank you for your best wishes, and I wish you success in other endeavors." Chen Chen replied.

After greeting the other party, Chen Chen sent off the previous owner of the data center, and then walked in alone.

Coming to the main control room of the data center, Chen Chen took out the key and locked the door, isolating himself in a small dark room full of wiring and steel.

Then, Chen Chen took out his mobile phone and clicked on the APP of "Little X Translation Assistant".

However, unlike the "Little X Translation Assistant" on the market, after verifying the fingerprint and face recognition, a childish voice suddenly came from the mobile phone.

"Dad, is there anything you can help me with?"

"I bought a service center in Switzerland, I want you to make a copy of yourself and occupy this place, and then I will connect you with another artificial intelligence, your purpose is simple, it is to kill the other person at all costs, and then replace the other party."

Chen Chen said, "I will physically assist you on the side." ”

"Understood, Dad."

Xiao X whispered, and then Chen Chen turned on the power supply in the main control room to connect the data center to the Internet, and Xiao X began to copy his own program and transmit it.

With the continuous evolution of Xiao X's intelligence, its core program has risen from dozens of G's to more than a dozen T, and ordinary computers can no longer accommodate it, and only places like data centers can accommodate its increasingly bloated body.

This time the copying time was very long, Chen Chen simply slept in the main control room, and by the time Xiao X reminded Chen Chen that the copying was complete, the time had already come to the middle of the night.

"Dad, I've finished copying, I'm X2 now, officially reporting to you!"

The voice of another little X came directly from the speaker in the main control room.

"Okay, let's get started."

Chen Chen rubbed his somewhat hazy eyes, and in order to prevent accidents, he first swallowed an NZT-48, and then unplugged the optical fiber of the data center.

Then, Chen Chen turned on the signal screen device to ensure that the entire data center was in a state of physical disconnection, and finally showed a STEM chip from the USB flash drive according to the previous method.

After doing all this, Chen Chen took out a USB data cable that had been prepared a long time ago.

However, unlike ordinary data cables, one end of this data cable is a USB port, and the other end is a plastic plate the size of a fingernail.

The plastic plate has a groove with sixteen tiny round holes.

This is the interface that Chen Chen specially made for STEM chips.

Chen Chen picked up the chip and inserted the chip into the interface according to the appropriate position.

Suddenly, the computer screen flashed twice, and little X2 came out of the stereo with a hint of excitement, "Dad, I saw it!" ”

"Did you fight?" Chen Chen asked.

"No, it's a weird protocol, and I need enough time to crack the ......," little X2 explained, "it's watching me, and it's wary of me." ”

"My hacking made it angry......"

"It's attacking me!" Little X2 reminded, followed by a moment of silence.

On the host screen at this time, Chen Chen only saw countless codes flowing out like a waterfall, almost changing at the speed of swiping the screen, but in about five minutes, Xiao X2 warned again, "The other party is going to break through the firewall I set, and my computing speed can't match it!" ”

"It's okay."

Chen Chen directly ripped the chip off the USB cable, and then pried open the chip and smashed the core processor inside into powder.

“……”

Seeing this scene, little X2 was silent for a moment, "Is this what Dad said about physical assistance?" ”

"It works, doesn't it?"

Chen Chen replied, "How about it, can you find the flaws of the other party based on the previous contact?" ”

"It can be done, but in the case that the other party's computing speed is far faster than mine, this flaw is almost meaningless."

"It's okay, we have a chance."

As he spoke, Chen Chen once again embodied a STEM chip from the USB flash drive and connected it.

This time, the little X2 lasted a few minutes longer than the first time.

"Dad, the other party is about to break through my newly arranged firewall, and this firewall against it still can't stop it!"

Hearing this, Chen Chen disconnected again and destroyed the STEM chip......

"Relying on an entire data center and tens of thousands of servers, it can't even compare with the other party......"

A few hours later, looking at the wreckage of dozens of chips piled up under his feet, Chen Chen couldn't help but be a little speechless.

It can be said that in the battle between the two artificial intelligences, each time the little X2 can learn a lot of experience from it and take precautions in advance, while the opponent is a new artificial intelligence every time, and there is no memory of the previous battle.

But even so, little X2 is still not a STEM opponent.

In addition to the difference in computing speed, there is also the fact that Xiao X's intelligence is not as good as the other party.

If Xiao X is an ordinary person with an IQ of 105, then the artificial intelligence in the STEM chip is a genius with an IQ of 140.

Of course, as long as you work hard, ordinary people can catch up with the footsteps of geniuses!

Thinking of this, Chen Chen smiled slightly, and once again embodied a STEM chip and connected it to the data cable......
