This upgrade seemed to be unusually long, unlike the previous ones, and it didn't take long to complete the upgrade.

Of course, Li Mu is not in a hurry, anyway, he has nothing to do now, so he waits with peace of mind.

In this way, after about an hour passed, the sound of the system finally sounded again.

"Upgrade complete!"

"The Mind Computer has been successfully upgraded to level 4, and the upgrade progress is 13201/100000."

升级一完成，李牧倏然就抬起了头。

此时的他，凡目光所见，他都能在脑海中建构起一个完全相同的模型出来，就像是眼前的这个房间，他一眼过去，就可以在脑海中搭建起一个分毫不差的模型。

Even if it's a fold in the quilt, or an undulation in the gap between the floor tiles.

同样的，更加清晰的视野，也让他几乎能分析出所有的尺寸。

他抬起手臂看了看自己的皮肤。

Every hairbrush on his skin was visible to him—he could even tell what the diameter of each hair, and how many.

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, and it would be down to single digits.

当然这种提升只是最表象的，更加深层次的提升，李牧在自己的脑海中可以清晰地感受出来。

Problems that once took a long time to think about can now be solved quickly, like the problem that Witten encountered in the process of deriving dimensional forces before.

And now, he doesn't need to use this comparison anymore, relying on his own thinking, it is enough to deduce the existence of dimensional forces.

“这次的提升可真有点猛啊……”

李牧的心中有些惊叹。

At this time, he knows very well how awesome he is now.

“对了，现在的算力相当于啥了？ ”

He asked, curiously.

The system responded: "The current computing power of the computer in my mind is equivalent to 20 NVIDIA Tesla A100 graphics cards. ”

Li Mu's face suddenly showed a surprised expression.

This time, the comparison actually became the graphics card!

Of course, both the graphics card and the CPU have strong computing power, and in terms of current technology, the general computing power of the graphics card is generally higher than that of the CPU.

As a professional graphics card, the A100 graphics card is widely used in a variety of professional research, with extremely high computing power, the price of such a graphics card is as high as tens of thousands of yuan, which is several times more expensive than any RTX3090.

"It seems that this upgrade is really powerful."

Li Mu sighed with emotion, but he didn't have long to be happy before he noticed that the energy required for the next upgrade was as high as 100,000!

"Holy! 100,000, why don't you grab it! ”

How long do you have to save 100,000?

The system doesn't say anything about this.

"Okay, good, 100,000 can't be changed, now that I've been promoted to level four, won't I give an extra reward or something?"

李牧吐槽了起来。

In the past, after he leveled up, he would be rewarded with a number of simulations of the real universe environment, but now that he has reached level four, he is not rewarded?

However, at this time, the system said: "This upgrade reward has been loaded during the upgrade process." ”

Li Mu was stunned: "What is it?" ”

The rewards for this upgrade have already been loaded?

"The brain computer after this upgrade is loaded with Bluetooth function and installed with Bluetooth 5.0 protocol."

"The host can now turn on the Bluetooth function of the computer in mind, connect with any electronic device that supports the Bluetooth 5.0 protocol, and transmit the relevant data."

Li Mu: "??!! ”

Wow!

Mind computers can finally connect with real electronic devices?!

God knows how long he's been thinking about it.

Then he immediately tried.

took out his mobile phone, and then turned on Bluetooth, and then he sank his mind into the computer in his mind, and after entering the panel, he found that there was an additional Bluetooth connection function on it.

随着他意念一动，便进入到了蓝牙连接面板，在可连接的设备中，果然出现了他手机的名字。

"Start a Bluetooth connection."

After giving the command, no window popped up on his phone to connect successfully, but the interface of the phone was already displayed in the computer in his mind.

Next, he can directly use his mind to control the mobile phone interface in his mind.

思考了片刻，他便直接点开了音乐播放器，开始播放周董的七里香。

随着一阵风呼啸的声音在脑海中响起，七里香的前奏随之开始。

"Sparrows outside the window, mouthing on telephone poles......"

Li Mu narrowed his eyes and enjoyed the music playing directly in his head.

What is brain amplification? Is this called brain release?

Li Mu, who felt the novelty, listened to it quietly

"Awesome!"

He couldn't help but sigh in admiration.

Although I don't know how the computer in his mind makes him hear music, I guess it is nothing more than using the auditory nerve to directly conduct it, just like the sound of the system.

Anyway, this function is so practical that he can listen to music without headphones in the future-

Ahem, well, as a scientist, he certainly has to think first of all about how this will help his research.

And that's hardly going to say.

He immediately took control of the phone in his computer and entered the arxiv.

As his mind moved, he searched for the paper published by Fermilab.

He downloaded the paper, connected it directly via Bluetooth, and transferred it to his computer.

Then he felt an extra document in his computer, and when he opened it, it was the paper.

He had already heard of this paper, but he had not read it before, and now, with the computing power of the computer in his mind, he had read it almost in just a few seconds, and then it took him more than ten seconds to fully understand what was being said in it.

That's the confidence that the computer gives him in his head.

"The data processing in this paper is really good."

I admired it 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 the data collected by experiments has always been an important topic.

It's no wonder that Fermilab was able to spot the overweight problem of the W boson.

当然，感慨完了这件事情后，李牧就马不停蹄地开始下载了其他各种各样的论文，以及各种各样的书籍，传输进脑海计算机中，看了起来。

In this way, in just 10 minutes, he read 50 papers and a book, and basically achieved a level of more than 95% comprehension.

95% is already a very high number, and if you want to fully understand it further, it will take some time, but obviously it will not be much.

这就是四级脑海计算机以及蓝牙功能带来的巨大作用，李牧顿时感到了无比的兴奋。

With this feature, his research will also become more effective with half the effort.

Compared with the past, the speed at which he absorbed information directly increased I don't know how many times.

In the past, he could only rely on visual information to conduct research.

That is, they receive information through their own eyes, and then transmit this information to the computer in their mind, so as to study it.

From now on, his mental computer can access all kinds of information directly from the Internet.

当然这也就有一个巨大的缺陷显现了出来——那就是他的身边得有一个能够连接网络的电子设备。

Without electronic devices such as mobile phones, the computer in the mind loses the medium to connect to the network, and naturally it cannot be connected.

Of course, in modern society, the time when the mobile phone is not around is probably very small, so there is no need to worry too much about this.

It's just that......

Li Mu looked down at the battery level of his mobile phone.

I don't think it works......

In addition to having to have electronic devices nearby, there are several drawbacks to this feature.

In just 10 minutes, the battery level of his phone has been reduced by 5% because it has been transmitting data.

Obviously, with the current mobile phone's battery, it is not enough to support long-term Bluetooth data transmission.

For mobile devices, this problem mostly exists, so it is best to use it with a power supply connected, which leads to the problem of non-mobility.

In addition, there is a flaw, that is, this matter is limited by the network download speed and Bluetooth transmission speed.

Bluetooth 5.0 supports up to 200Mbps data transmission speed, and this speed is only theoretical, and the actual transmission speed is generally lower.

However, Li Mu suddenly thought for a moment.

It seems that the computer connected 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 computer in mind......

If you think about it......

His mind panned, and then he re-entered the computer in his mind, searching for all the nearby devices that could be connected.

Soon, more than a dozen devices appeared in the list, and now due to the existence of various wireless devices, people have become accustomed to turning on the Bluetooth function, which is convenient for Li Mu.

So, he directly used his mental computer to connect to these devices, and finally filtered through the two computers that were connected to the power supply.

This way, you don't have to worry about the power supply.

"Not bad."

Li Mu nodded with satisfaction, and said sorry to the owners of the two devices in his heart.

Let's borrow your computer for now.

Of course, he didn't forget to connect to his computer.

Multiple devices are transmitted together, which brings more information.

In this way, for the whole morning, he enjoyed the acquisition of knowledge.

With this feature, give him time and he will become omniscient!
