The continuous processing performance of the Portable Smart Brain is 100 quintillion operations per second, which is 100 times that of Sunway TaihuLight. As for the first-tier super brain, its continuous performance is $10^{36}$ operations per second; the second-tier super brain reaches $10^{45}$ operations per second; and the third-tier super brain even achieves $10^{54}$ operations per second. With each tier upgraded, the performance differs by a factor of 100 million.
Manufactured based on quantum technology, the Portable Smart Brain is completely immune to viruses and hackers. Quantum phenomena originate at the microscopic level, but they can have a significant impact on the real world. No matter how far apart two entangled particles are, as long as the state of one particle is measured, the state of the other particle will be affected accordingly. If anyone attempts to observe the particles during transmission, the state of the particles will change, and the entangled state will be destroyed. This property makes it possible to create a quantum communication system that is theoretically impossible to destroy or hack, because a snooper merely performing an observation will destroy the information. Therefore, using a Portable Smart Brain is exceptionally secure. The Portable Smart Brain has become standard equipment for citizens in advanced civilization societies, and civilized citizens generally are equipped with one from childhood.
Seeing this, Li Xiangdong remembered the several Portable Smart Brains he had once taken out from the Ring. He immediately searched them out, picked one up, and put it on his left wrist.
The Portable Smart Brain looked similar to a wristwatch on the Blue Star, slightly larger than mechanical men's watches on the market. Both the dial and the strap were silver-gray, except there was no glass screen.
On the front left, there was a black dot about one millimeter in size, which the manual indicated was a camera and a laser head.
On the right side, there were two slightly protruding buttons, which were the startup button and the projection button respectively. Pressing the front button caused a speck of light to flash on the smart brain's camera, and the smart brain started up. Pressing the projection button again brought up a beam of light right above the smart brain. The operation was somewhat similar to the light screen of the Ring earlier, allowing one to carry out personalized settings step by step according to the prompts.
He originally wanted to casually name the Portable Smart Brain "Xiaobai", but realizing that name was used far too much, he casually gave it the formal name of "Xiaoqiang", with the boot password being "Great Luck and Success".
Each Portable Smart Brain had a specific number, which could be used for communication just like a mobile phone number. The Portable Smart Brain could call directly like a walkie-talkie on the Blue Star, except that the connection distance was much greater; they could connect directly without a communication network within a range of one-tenth of a light-year of each other.
How far of a distance is "one-tenth of a light-year"?
Taking the Solar System as an example, the currently detected outermost edge of the Solar System is the Oort Cloud, which has a diameter of about 2 light-years. If calculated based on the orbit of the dwarf planet Pluto, the diameter is about 11.8 billion kilometers (about 0.00025 light-years). In other words, although the communication range of the Portable Smart Brain cannot cover the entire Solar System, it far, far exceeds Pluto in the Solar System.
What was most advanced was that the Portable Smart Brain emphasized the word "Smart". The smart brain possessed extremely high intelligence and could connect to the network via wireless internet to learn independently, rapidly adapting to the language and culture used by members of different civilizations.
The smart brain's multimedia functions were also formidable, coming with a super nano-mini speaker and microphone. It could play videos, browse the internet, take photos, record audio, and shoot videos through the light screen—not a single function was left out.
The smart brain also possessed a black technology that the Blue Star Civilization was currently exploring: human-computer interconnection. It actually supported a direct connection between the human brain and the smart brain, provided there was one prerequisite: the user's spiritual force must be able to project outward. Li Xiangdong could not comprehend this point yet. After checking some materials, he learned that after taking the Genetic Potion for the second time, human spiritual force could be greatly stimulated, allowing most people to achieve human-computer interconnection. Since it could not be achieved right now anyway, Li Xiangdong understood the relevant principles and did not continue researching it.
The office functions were even more freakishly powerful: voice-input-to-text conversion, memos, video conferences, and so on. Operations did not require moving one's hands; just speaking and giving commands would do.
Having hurriedly finished reading the manual, Li Xiangdong immediately commanded Xiaoqiang to search for a wireless network, select the home network to connect, and simultaneously enable the learning function. With the network connection successful, before long, the smart brain actively emitted a sound: "Master, based on the current network speed, autonomous learning will take 1 to 3 hours. Please wait patiently."
Hearing the voice emitted from the smart brain, it took Li Xiangdong a good while to react. This smart brain really was no joke; it truly could converse with people.
Li Xiangdong listened and asked casually, "Xiaoqiang, can other Portable Smart Brains connect to the network and learn at the same time?"
The smart brain responded immediately, "Master, there is no need for other smart brains to connect to the network. Once this smart brain finishes learning, as long as learning sharing is enabled, other smart brains can complete their upgrades in just a few seconds."
"The functions are truly powerful!" Li Xiangdong couldn't help marveling. Comparing a Blue Star smartphone to a Portable Smart Brain was like comparing primitive stone tools and wooden sticks to a modern automatic rifle; they truly were not products of the same era.
Time always flies when one is focused on studying. By the time Li Xiangdong snapped out of it, it was already evening. Perhaps because he had just consumed the Genetic Potion not long ago, he didn't feel hungry even though he hadn't eaten at noon.
Just like that, Li Xiangdong had just synchronized the upgrade of five smart brains when over on her side, Li Yin had already finished washing up, put on her slippers, and came to look for Li Xiangdong.
"Brother, you're so awful! You didn't tell me beforehand that after drinking that beverage, I'd sweat so much all over. It smells to high heaven!"
As soon as Li Xiangdong opened the door, Li Yin launched into a barrage of complaints right off the bat.
"Look at you, hurry up and go look in the mirror. Not only have you grown taller, but your skin is whiter, more tender, and you've become even prettier!"
"Really?!"
Li Yin clattered back to her room to look in the mirror. "Ah! Wonderful! The skin on my face really has become much smoother."
With a burst of exclamations, another sound of pattering footsteps went back downstairs.
Little Sister couldn't wait to share her changes with Dad, Mom, Grandpa, and Grandma, and she also wanted to see their results.
Li Xiangdong also went downstairs to the living room and found that Grandpa, Grandma, Dad, and Mom had all come out.
Grandpa and Grandma had changed the most. Their originally completely gray hair had almost all turned black, the age spots on their hands and faces had also vanished, and even their wrinkles were barely visible.
Dad and Mom looked as if they had suddenly grown ten years younger. Originally middle-aged people approaching fifty, they now looked about like young people in their thirties.
Seeing everyone staring at him, Li Xiangdong knew the family had plenty of questions and that he still had to make up a story to hoodwink them.
"Ah, I was too hasty just now and didn't tell everyone about the true effects of this beverage. Actually, the biggest function of this beverage is to improve physical fitness. After drinking it, not only can it make people younger, but it can also enhance strength and speed, and can even make one smarter."
