So now he only needs to emit a little ultrasonic wave from time to time, and he can sense the situation within a kilometer radius.

Within this one-kilometer radius, it is clear at a glance how many people there are, who is where, who is carrying a gun, who is in a shooting posture, etc. From now on, it is not so easy for the enemy to assassinate him.

Of course, in addition to indirectly improving the working capabilities of various extraordinary sensory organs, the most satisfying aspect of this biological secondary brain is its portable supercomputing function.

This portable supercomputer has powerful computing power and is directly connected to the "consciousness" of the human brain, possessing super-high comprehension capabilities.

No matter you want to use it to calculate a problem, assign a task to it, or even want it to control your body to do something, it can be used.

Except that its IQ is slightly lower than that of the third-generation and second-generation artificial intelligence Jarvis, it has no other shortcomings.

Of course, in the future Lin Feng may be able to program the third-generation artificial intelligence Jarvis into the biological secondary brain, so that he can have a truly portable artificial intelligence.

But after thinking about it, Lin Feng decided not to perform such a dangerous operation. After all, there is a risk of the artificial intelligence Jarvis getting out of control.

"Let's get the injection first."

After thinking about many things, Lin Feng picked up a large bottle of needle-free syringe containing the biological sub-brain, stabbed it directly into his neck artery, and then pressed the needle-free syringe.

Speaking of which, this biological secondary brain was specially developed to adapt to his genes, and it has a security lock to prevent cracking.

Once it leaves his body for a long time, it will begin to gradually disintegrate and destroy everything in the cells, preventing the enemy from cracking the biological secondary brain's technology.

At this time, the biological secondary brain contained a part of the body fluid of his active cells and had not yet started the self-destruction program, so Lin Feng had to implant it immediately.

Otherwise, once the body fluids containing his active cells lose their activity and the biological sub-brain activates the self-destruction program, it will be disastrous.

After all, neither he now nor in the next few decades will be able to create the same biological secondary brain.

Of course, just because it cannot be manufactured now does not mean that the biological secondary brain cannot divide and multiply itself.

After all, it is more similar to a biological cell because it has the same ability to divide and replicate itself as a biological cell.

Once it detects that Lin Feng's body nerve cells are not covered and entangled, it will self-divide and proliferate and entangle that part of the nerve cells.

On the contrary, if it leaves the body, it will activate the self-splitting, destructive and disintegration program to prevent the enemy from obtaining the technical information to crack the biological secondary brain.

Therefore, as long as there is a need, Lin Feng can use his self-division and proliferation to create countless Lin Fengs.

This makes him like Orochimaru, who cannot be killed no matter how hard you hit him, unless all his secret methods of resurrection are destroyed.

But these are all things for the future. After all, it is not easy to build a safe resurrection base.

Moreover, it is not an easy task to suppress the activity of the removed body tissue.

Lin Feng needs to develop a durable fully automatic device, and then keep cutting that part of the body tissue just like the original planarian experiment, so that it is always in a state of being cut and repaired.

Only in this way can we avoid problems for decades or even hundreds of years.

In this way, even if the Earth's civilization is destroyed by a cosmic gamma ray, after dozens or even hundreds of years of buffering, the surface will cool down and give it a chance to rebuild human civilization.

So Lin Feng, having made his decision, began his busy research and development work. As for finding and secretly building a resurrection base, he also instructed Jarvis to be in charge.

However, the outside world does not know that Lin Feng has been injected with a biological secondary brain with a value of 6.6 million experience points.

They didn't know what Lin Feng's acquisition of the biological secondary brain meant to human civilization. Of course, whether they knew it or not didn't matter, because the effect of this biological secondary brain was too strong.

Lin Feng will not let them know for at least a hundred years. After all, no one wants to expose their weaknesses, especially when it comes to their own resurrection.

On the contrary, even if the third-generation brain-computer interface chip is released in the future, it will not be a biological secondary brain.

It is the third-generation brain-computer interface chip developed independently by Xingtu Technology!

……

Time passed slowly, and in the blink of an eye it was already a week after the press conference.

On this day, the first batch of 10 users who received implants of the second-generation brain-computer interface chips can finally officially activate their second-generation brain-computer interface chips.

This directly attracted the attention of countless people around the world, making billions of people around the world pay close attention to this matter.

It can be said that on this day, no matter you are a top superstar, a business tycoon, or a political leader, you cannot snatch the news attention of the second-generation brain-computer interface chip.

Among them, many of the smart people who were the first to try it out naturally prepared for live broadcasts early on.

So on this day, they started live streaming directly on platforms such as Bilibili, Douyin, and YouTube.

"Hello everyone, I am 'Sun Qifa', from Jiangsu, welcome everyone to watch my live broadcast."

At this moment in the live broadcast room, a middle-aged man was smiling and greeting hundreds of thousands of netizens in the room.

"Stop talking nonsense and start the brain-computer interface chip."

"Yes, Daxia people, hurry up. It's 8:16 over there, but it's : over here. I've been waiting until now just to see the result. Hurry up."

"That's right, stop talking nonsense."...

Netizens in the barrage complained about the anchor Sun Qifa, and Sun Qifa was helpless under the pressure of people.

So he took back his 2,000-word speech and said:
"Okay, then I won't waste any more time and just start the live broadcast."

Before this live broadcast, he had actually activated the second-generation brain-computer interface chip.

The so-called activation of the brain-computer interface chip is naturally in front of a special magnetoencephalography instrument, and then the artificial intelligence Jarvis controls the second-generation brain-computer interface chip to activate a certain cocoa growth electrode.

The dedicated magnetoencephalography instrument will then record the location of the cocoa-grown electrode in the brain, allowing the artificial intelligence Jarvis to record it and establish a personal brain database.

This process is actually quite troublesome. After all, the second-generation brain-computer interface chip has more than 3 billion cocoa-grown electrodes.

In addition, during the activation process, the human body may feel pain, convulsions, or other abnormalities.

But the good thing is that it only needs to be activated once, and it will not need to be activated again in the future. After all, the information of the cocoa growing electrodes in various parts of the brain has been recorded.

The positions of the more than 30 billion cocoa-grown electrodes implanted in various parts of the brain will not change easily, so there is naturally no need to waste time by repeated recording.

Therefore, the host Sun Qifa can directly start the test mode without activating the mode first. (End of this chapter)
