The next morning, there was a meeting at the base.
When everyone arrived, the commander spoke solemnly, saying that a level three contact occurred at Base 153 last night. According to the available intelligence, it was judged to be No. 032 Feather Angel. The giant weapon Kui Niu and the Angel died together. The driver, Comrade Jian Bu, protected him in the fierce battle. The base gave up the opportunity to escape and ultimately died heroically. This contact resulted in a total of 133 deaths and 206 injuries, making it the battle with the heaviest casualties in the past two years.
Everyone stood and observed silence.
After the meeting, the Operations Office received an internal report, which was more detailed information on the third-level contact of the 153 base last night. Angel No. 032 came from the Qinghai-Tibet Plateau and overlooked Dujiangyan City on the Qionglai Mountains at an altitude of 4,000 meters. All weapons could not catch up with it. The giant Kui Niu attacked with half its body, using six high-altitude balloons with a radius of six meters and a height of 2,200 meters to drag it to the stratosphere tens of thousands of meters above sea level. It penetrated the sky at high speed with free fall and sprayed insecticides with it. The entire battle lasted only one hour and forty-seven minutes to break down the Feather Angel. After the Feather Angel died, its energy spiraled up and down in an extremely narrow vertical space, punching the earth through.
"Punched through the earth?"
"We estimate that it penetrated the earth." Chen Yu sat on the edge of the bed, holding a book in his hand, "Because the afterglow it shot upward is 400,000 kilometers high. There is no reason that it would be shorter downward. In the three-dimensional universe The material is like air in front of angels, and it easily creates a super deep hole that has never been reached in human history."
"Can we see the United States from here?" Phytophthora asked.
"If the hole doesn't collapse, yes." Chen Yu nodded.
Phytolacca spread out the materials in his hand on the bed. Between the fine words were black and white photos of Mohu, which were taken by drones at night. Feather Angel is just as its name suggests, it is a distant, thin, and exuding The shadow of the glow glows because the freely moving gas molecules in the air collide with the angel and are annihilated, leaving only photons to escape. It floats on the top of the mountain like a cloud and is as gentle as a feather.
Faced with such a huge angel, humans generally adopt the most cautious attitude, because it is likely to be close to the p-yang limit. Once it reaches the p-yang limit, the angel will collapse inward into a black hole.
This was the first time Shanglu saw Kui Niu.
The last image of Kui Niu left in this world is only half of its body. It looks like a dry animal skeleton in the light beam of the spotlight. In order to reduce weight, this giant machine abandoned its lower body and removed all its armor. Five hangings were hung under it. The kilometer-long cable and the Riemann probe are hoisted up to reveal a giant jellyfish or squid.

"What a pity." Chen Yu whispered.
"Do you know him?" Shanglun asked.
"You mean Jian Bu?" Chen Yu said, "He was on duty at 151 and he is a very nice person."
"What kind of person is he?"
"I'll give you an example, and you'll understand." Chen Yu covered his face with the book, "There is a large asylum in Mianzhu, which is dedicated to taking in the elderly who lost their children in the collapse and had nowhere to go. Some people Take care of their lives and help them take care of their funerals, because they all have a son named Jian Bu."
Phytolacca walked out of the dormitory, raised his head and looked at the dark and low sky, imagining that earth-shattering blow falling from the sky.
"That's awesome."
he said in a low voice.

The work office finally touched the legendary rabin-shang wall. They crowded in front of the computer screen in amazement, watching the twisting curve descending all the way, and then jumping on the value of 0.12, six After more than ten tests, the closest one was close to 0.12, but the next test result went back up, as if there was an invisible wall blocking it. It was approaching mid-to-late November, and Shen Jiang had been working on the meg-bci system for more than 160 hours, doing thousands of questions. Wang Feng's songs were recited by heart, and the meg-bci system was making rapid progress, singing along - - Until today, "Bang!" The ground suddenly hit the south wall. My uncle Wang Xiangbing opened his eyes wide and said it was amazing. What the director said was actually true.
Li Wenxuan said, did you always think what he said was false?
Wang Xiangbing said that we cannot be superstitious about authority. Do you understand? We must maintain the ability to think independently and look at problems with a critical eye...
"The bridge!" Bai Shu yelled funny.
Shanglu opened the door and came in.
"Director, is our work fruitful?" Wang Xiangbing gave a thumbs up and pointed toward the computer, "We have reached 0.12. If we go to the next step, we will be successful."
Phytolacca sat in his seat, put back all the messy folders on the table, and stacked all the experimental logs.
"When we did this in the Science City Chengdu Institute, the reason for our final failure was that we couldn't take the last step. Do you still remember that I told you about the characteristics of the meg system? It has excellent performance in time resolution and spatial resolution. It is balanced and has no major shortcomings, but it is naturally less accurate than the intrusive ieeg system. This is determined by its structure and is an inherent shortcoming."
"So we need to tailor-make a single-person stand-alone machine." Bai Shu said.
"Yes, but this is not a panacea." Phytolacca said, "I have never said that a tailor-made system will definitely be able to break through the rabin-shang number wall. Judging from the current test results, with the experimental accuracy Continuously improving, it still hit the same wall as previous experimental results."
"What is the nature of the rabin-shang wall of value?" Li Wenxuan asked.
Phytolacca thought for a moment and chose an easy-to-understand explanation.
"I can only tell you my own understanding, and it may not be correct... We all know that the meg system is essentially guessing what the driver's brain is thinking. Since it is guessing, it is essentially a probability theory. The problem, simply put, is that the rabin-shang number is the superficial manifestation of this probability."
Probability is the most common and magical thing in the world. It symbolizes some kind of unity. If you use something to describe it most appropriately, then it is undoubtedly "a big invisible hand". In meg During the development process of the system, the algorithm may be right or wrong in identifying and distinguishing human brain activity. A single test may have no trace or pattern. Once the number of tests increases, the commonalities in the differences will immediately become apparent.
The rcbi team said that the Bayesian formula is the theoretical basis that supports all AI algorithms. It is also a powerful tool for people to infer what this black box is doing. If pure mathematical language is used to describe the wall of rabin-shang numbers, then I'm afraid the end result will be layers of Bayesian formulas like a layer cake.
"We hope to chop the brain and the meg system into pieces, cut them into the smallest neural activity units, and cut them into the most basic chip circuits. In this data space composed of the human brain and AI, let the two One-to-one correspondence between spaces, but obviously this is impossible. The human brain is a black box for us now, and AI is also a black box for us now. So it is better to let AI imitate the brain and let the black box learn from the black box. We cannot What AI understands may not be incomprehensible. This is what I told you before..."
"Build an electronic second brain." Zhang Zhong asked, "Then what should we do next? Continue to do the questions?"
"It still has to do the questions." Phytolacca nodded, "But in the second stage, it has to learn some more abstract content."

"Wow, you sound so incompetent. You are the kind of incompetent parents who ask their children to do things they cannot do themselves. If they cannot break through the rabin-shang number wall, they expect the meg system to break through on its own." Shen Jiangshi Shi Ran leaned back on the chair and looked at the ceiling with both eyes, "When this AI imitates my brain to a certain extent, it will be able to guess what I am thinking very accurately, and then the rabin-shang number wall will break through." Yes, right?"
There was a little pride on Shen Jiang's face when she said this, and Shang Lu's wishful thinking was clearly understood by her.
"Yes." Phytolacca sat down on the chair opposite her and put his hands on his knees, "That's what it means."
"Is it that smart?"
"No." Phytolacca shook his head and admitted straightforwardly, "Theoretically, it should imitate your brain. The more comprehensive the imitation, the better. But we obviously don't have this technical level. Even the latest and most powerful transformer models can't do it. So, on an implementation level, we hope it captures the preconscious part of your brain."
"subconscious?"
"No, it's not the subconscious, it's the preconscious." Shanglue explained, "You know that the rabin-shang number is a comprehensive measure of the accuracy of the bci system. Take the time accuracy as an example. The current meg system can achieve the same in time accuracy. Millisecond level, about 5 milliseconds, that is to say, when an idea sprouts in your mind, it can be perceived after 5 milliseconds, but ieeg can shorten this time to less than 1 millisecond. The difference is 4 milliseconds. You are on the battlefield. Having dealt with angels before, I know that 4 milliseconds is enough to turn the tide of the battle."
"Then shorten this time! Supervisor, this is what you do."
"If it were so easy to shorten, the rabin-shang wall would not be called a wall." Phytolacca said, "The MEG system is head-mounted, and the ieeg is invasive, separated by such a thick brain tissue. , skull and scalp, the signal analysis speed of the former will inevitably be slower. This is determined by the mechanical structure, design form and working principle of the system, and cannot be modified. "
"What should we do?"
"There is a fact that you must understand, leader. When you form a certain idea or have a certain idea in your mind, it will be too late to understand it."
Shen Jiang was stunned for a moment: "What do you mean?"
"If meg and ieeg are compared to two athletes running a race, then the starting line of the two people is inconsistent." Phytolacca explained, "Due to a congenital defect, meg is 20 meters behind the other when it starts. When you start the gun, , its defeat is sealed.”
Shen Jiang was stunned.
"If you want the MEG system to beat the IEEE, or you want to shorten the time accuracy to less than 1 millisecond..." Phytolactin went on to say, "Then it must get a head start and start before your starting gun sounds. In other words, It has to know what you’re going to think next before you do!”
