The upgrade this time seemed to be particularly long, unlike before, it didn't take long to complete the upgrade.
Of course, Li Mu was not in a hurry. He had nothing to do anyway, so he could wait patiently.
Just like that, about an hour later, the system's sound finally sounded again.
"update completed!"
"The brain computer has been successfully upgraded to level 4, and the upgrade progress is 13201/100000."
As soon as the upgrade was completed, Li Mu suddenly raised his head.
At this moment, he could construct an exact model in his mind of whatever he saw. Just like the room in front of him, he could construct an exact model in his mind at a glance. .
Even if it's a wrinkle on the quilt, or an ups and downs in the gap between the floor tiles.
Likewise, his clearer vision also allowed him to analyze almost all dimensions.
He lifted his arm and looked at his skin.
Every hair on the skin was clearly visible in his eyes - he could even see the diameter and number of each hair.
If a person with hair several times thicker than Professor Wu Mengyuan stood in front of him now, he would probably be able to tell at a glance how many hairs he had, down to single digits.
Of course, this kind of improvement is only the most superficial, and Li Mu can clearly feel it in his mind as a deeper improvement.
Problems that once took him a long time to think about can now be solved quickly. For example, when he deduced dimensional force, he needed the problem Witten encountered for comparison.
But now, he no longer needs to rely on this kind of comparison. He can deduce the existence of dimensional force by relying on his own thinking.
"This improvement is really drastic..."
Li Mu was a little surprised in his heart.
At this time, he knew very well how awesome he was now.
"By the way, what is the current computing power equivalent to?"
he asked curiously.
The system responded: "The current computing power of the computer in your mind is equivalent to 20 NVIDIA Tesla A100 graphics cards."
Li Mu's face immediately showed a surprised expression.
This time the comparison was actually about graphics cards!
Of course, both graphics cards and CPUs have strong computing power, and as far as current technology is concerned, the general computing power of graphics cards is generally higher than that of CPUs.
As a professional graphics card, the A100 graphics card is widely used in a variety of professional research. With its extremely high computing power, the price of such a graphics card is as high as tens of thousands of yuan, which is higher than the RTX3090. Several times more expensive.
"It seems like this upgrade is really impressive."
Li Mu sighed with emotion, but before he was happy for a long time, he noticed that the energy required for the next upgrade was as high as 100,000!
"Holy crap! One hundred thousand, why don't you go and grab it!"
How long does it take to save 100,000?
The system has no indication of this.
"Okay, okay, 100,000 yuan can't change it. Now that I've reached level four, shouldn't I be given an extra reward or something?"
Li Mu complained.
In the past, after he upgraded, he would be rewarded with one simulation of the real universe environment, but now he is not rewarded when he reaches level 4?
However, at this time, the system said: "The rewards for this upgrade have been loaded during the upgrade process."
Li Mu was stunned: "What the hell?"
Have the rewards for this upgrade been loaded?
"The upgraded brain computer is loaded with Bluetooth function and installed with Bluetooth 5.0 protocol."
"The host can now turn on the Bluetooth function of the brain computer, connect with any electronic device that supports the Bluetooth 5.0 protocol, and transmit relevant data."
Li Mu: "??!!"
Damn it!
Can the computer in your mind finally be connected to real electronic devices? !
God knows how long he had been thinking about this matter.
Then he tried it immediately.
He took out his mobile phone and turned on Bluetooth. Then he turned his mind to the computer in his mind. After entering the panel, he found that there was a Bluetooth connection function on it.
With a thought, he entered the Bluetooth connection panel, and sure enough, the name of his mobile phone appeared among the connectable devices.
"Start Bluetooth connection."
After giving the command, no window indicating a successful connection popped up on his phone, but the phone's interface was already displayed on the computer in his mind.
Next, he can directly use his thoughts to control the mobile phone interface in his mind.
After thinking for a moment, he directly clicked on the music player and started playing Jay Chou's Qilixiang.
As the sound of howling wind sounded in my mind, the prelude of Qilixiang began.
"The sparrows outside the window are talkative on the telephone poles..."
Li Mu narrowed his eyes and enjoyed the music playing directly in his mind.
What is brain release? Is this called brain release?
Li Mu, who felt the novelty, listened to the song quietly.
"Awesome!"
He couldn't help but sigh in admiration.
Although he didn't know how the computer in his mind allowed him to hear music, he probably thought it was nothing more than direct transmission through the auditory nerve, just like the sound of the system.
No matter what, this function is really practical. From now on, he can listen to music without wearing headphones——
Ahem, well, as a scientist, of course he must first think about how this will help his research.
And this almost goes without saying.
He immediately controlled the mobile phone in his mind's computer and entered arxiv.
With a thought, he searched for the paper published by Fermilab.
Download the paper and directly use Bluetooth connection to transfer the paper to his brain computer.
Then he felt that there was a document in the computer in his mind. When he opened the document, it was this paper.
He had heard about this paper, but had not read it before. But now, with the help of the computing power of the computer in his mind, he almost finished reading the paper in just a few seconds, and then again It took more than ten seconds to fully understand what was being said.
This is the confidence that the brain computer gave him.
"The data processing method in this paper is really good."
I sighed a little in my heart.
It is conceivable that this new data processing method should also come from a person with strong mathematical ability.
In high-energy physics, how to process data collected from experiments has always been an important topic.
It’s no wonder that Fermilab was able to discover the overweight problem of the W boson.
Of course, after lamenting this matter, Li Mu immediately started downloading various other papers and various books, transferred them to the computer in his mind, and started reading them.
In this way, in just 10 minutes, he read 50 papers and a book, and basically achieved more than 95% understanding.
95% is already an extremely high number. If you want to further fully understand it, although it will take some time, it obviously doesn't take much.
This is the huge role brought by the level-4 mental computer and Bluetooth function, and Li Mu suddenly felt extremely excited.
With this function, his research will become more efficient.
Compared with the past, his speed of absorbing information has increased by countless times.
In the past, he generally could only rely on visual information to conduct research.
That is to say, information is received through one's own eyes, and then the information is transmitted to the computer in the brain for research.
From now on, his brain computer can obtain all kinds of information directly from the Internet.
Of course, this also has a huge flaw - that is, he must have an electronic device that can connect to the Internet.
Without electronic devices such as mobile phones, the brain computer loses the medium to connect to the Internet, and naturally cannot connect.
Of course, in modern society, the time when your mobile phone is not around is probably very small, so there is no need to worry too much about this.
It's just...
Li Mu lowered his head and looked at the battery of his mobile phone.
It doesn't seem possible...
Besides having to have electronic devices nearby, there are several drawbacks to this feature.
In just ten minutes, his phone's power had dropped by 5% due to continuous data transmission.
Obviously, the current battery of mobile phones is not enough to support long-term Bluetooth data transmission.
For removable devices, most of them have this problem, so it is best to use them when connected to the power supply, which leads to the problem of immobility.
In addition, there is another flaw, that is, this matter is limited by the network download speed and Bluetooth transmission speed.
Bluetooth 5.0 supports a maximum data transmission speed of 200Mbps, and this speed is only theoretical, and the actual transmission speed is generally lower.
But Li Mu suddenly thought for a moment.
It seems that connecting the brain computer to Bluetooth does not require the consent of another device.
Moreover, there seems to be no limit to the number of Bluetooth devices that can be connected to the brain computer...
If you think about it...
His heart moved, and he re-entered the computer in his mind, searching for all nearby connectable devices.
Soon, a dozen devices appeared on the list. Nowadays, due to the existence of various wireless devices, people are accustomed to turning on the Bluetooth function, which is convenient for Li Mu.
So, he directly used his brain computer to connect to these devices, and finally, after screening, two computers were left that were connected to the power supply.
In this way, you don't have to worry about power supply.
"good."
Li Mu nodded with satisfaction and said sorry to the owners of the two devices in his heart.
I'll borrow your computer temporarily.
Of course, he didn't forget to connect to his computer.
Multiple devices transmit together, bringing more information.
In this way, he enjoyed the acquisition of knowledge for the whole morning.
With this function, give him time and he will achieve omniscience!
