After lunch, Shang Lu rode Chen Yu's broken bicycle along the mountain road back to the dormitory, of course, he could go back in the tunnel, but he felt that the wind in the cave was strong and cold, and it happened that there was no big sun outside today, the breeze was gentle, Shang Lu whistled, wore a white hat, and his trouser legs rubbed against the lush weeds and bushes on the side of the road, and the broken bicycle "creaked".

"Commercial ——! Go back? ”

There were cadres who knew Shang Lu on the side of the road and waved at him.

"Go back, don't be on duty in the afternoon, don't be on duty, don't be on duty, don't be on duty, la!"

Shang Lu rode over the top of the slope, spread his legs, and his bicycle rushed all the way down the gentle slope.

"Superintendent?" Someone called out to him by the side of the road, and when he heard it, it was the voice of a girl.

"Yes, yes!"

Shang Lu twisted his neck and looked back, his eyes widening.

"What does the leader command? I will definitely do it within the scope of my duties! Don't give up -! ”

"Bang!" As soon as it hit the ground, the bike crashed into the weeds at the end of the downhill corner.

It's rare to have such a leisurely day in 151, when Shang Lu came to report, the base was under the threat of the 092 lighthouse angel, and it has been in a state of combat readiness, it can be said that he is in the line of fire, and the enemy supports, and now the 092 lighthouse angel has been successfully eliminated, and the huge threat to human survival no longer exists - simply put, it is time to finally kill a small boss, and it's time to rest, if the future facing humanity is an RPG game, then the lighthouse angel is just a small monster encountered halfway, No one knows when the game will be cleared, and no one knows if there will be a final boss.

It may be a never-ending struggle, and every time you risk your life to destroy an enemy, there will always be more enemies waiting in line.

There will be 093 after 092, 094 after 093, and 095, 096, and 097 after 094, assuming that the winning rate of human beings against each angel is 90%, then the probability of winning ten games is 35%, and the probability of winning all twenty consecutive battles is 12%.

As long as there are enough angels, the chances of humanity winning forever are infinitely close to zero.

And it only takes one defeat for all the previous victories of humanity to be wiped out.

When he became his own institute, Shang Lu always thought so.

But most of the people in 151 are different from the people who have come to their own places, which makes Shang Lu, who has been in Science City for a long time, unable to adapt for a while, the people here seem to have some kind of blind optimism from unknown sources, they discuss new songs on the Internet in their spare time, discuss the beautiful girls of the art troupe, and the guys in the workshop office still have the heart to rehearse their embarrassing welcome ceremony, even if it is the most annoying 1047 in the 110 workshop system - he is also a good person who is silly and silly (Shang Lu really thinks he is a good person), Every day, he worked hard for the position of the chief engineer of the base until the day he died.

In 151, there were so many people around Shang Lu, except for Old Man Ji, the only person who showed a strong sense of long-term distress was the business chief, who was worried about what to do if the oil reserves were exhausted every day, so he went all out to tackle coal-fired aero engines.

In comparison, the City of Science is a place with an annual suicide rate of more than 7 per 10,000.

Shang Lu rode his bicycle into the gate of the courtyard and saw a motorcycle parked in the courtyard, and the confidential messenger from the mailroom of the division office was getting off the motorcycle, and a locked iron box was tied to the back seat of the car.

"Merchants?" The little soldier was a little surprised to see Shang Lu riding a bicycle in, "Hey! You came just in time, you have your special delivery! ”

"Just delivered?" Shang Lu braked the bicycle in front of him, and his legs were clubbed on the ground, "It's been three days." ”

"Hey, do you know that confidential items are delivered slowly?" The communicator took out the list and asked Shang Lu to sign for it, "Come on, come on, sign for it, I'll go back and pay it." ”

Shang Lu took the pen and paper and bowed his head to sign his name.

The correspondent opened the lock of the iron box with the key, and took out a large khaki cardboard box from inside, which was tightly sealed with tape and seals, and the seals were covered with bright red seals:

Archives of Chengdu Institute of Automation, Chinese Academy of Sciences.

314 Office of the Working Committee.

Shang Lu signed for the express mail and moved the cardboard box into his dormitory room.

Chen Yu was not on duty this afternoon, and was leaning on the bed reading a copy of Yu Hua's "Xu Sanguan Selling Blood", when he saw Shang Lu coming in with a heavy cardboard box, put down the book and asked, "Little Chief Engineer, what did you buy on Jingdong again?" ”

"Erotic lingerie." Shang Lu entered, panting and placing the box on the floor, and then pushed in.

"So much?" Chen Yu said, "That's enough for you to wear until you are 80 years old." ”

"Half of yours." Shang Lu tore off the seal, took out the key to cut the tape, opened the box, and there were dozens of thick blue cover notebooks neatly stacked inside, and he took out the notebooks one by one and counted them.

Chen Yu put down the book, crawled over and picked up a copy casually, only to see that the blue cover of the notebook was printed with black CASIA and the emblem of the automation institute, which was obviously sent by Cheng Zi, he glanced at it and saw a dark red chapter printed on the upper right corner of the cover: Top Secret.

Chen Yu's hand shook: "The top secret documents were brought to the dormitory?" There are no three irons and one device in the dormitory. ”

"yes." Shang Lu didn't care, "Temporarily store it for one night, and take it to the office tomorrow." ”

"Violating the regulations." Chen Yu said.

"If you violate, you will violate, God knows you and I know." Shang Lu buried himself in counting the number of notebooks, "You can also see it if you want, although in principle, the people in your headquarters need to be approved by the chief engineer to see this." ”

Chen Yu flipped through the notebook in his hand, which was densely packed with scribbled handwriting, formulas, tables and hand-drawings.

"Who wrote this?"

"I wrote it." Shang Lu sat on the floor, "I stayed in the institute for the experimental logs and technical documents of the previous years, and I thought I would never need them again. ”

Chen Yu couldn't understand what was written in these notebooks at all, not only Chinese but also English, he frowned and looked at it for a while, feeling that it didn't matter if this thing was certain and top secret, because few people in the world could understand it.

"Explain, little chief, what are these things?"

"I'm collaring ...... Something I left over from when I was working in the RCBI group. ”

"RCBI group?"

"The Research Center for Brain-inspired Intelligence, which used to be a department under the Institute of Automation, is now a technical research group, called the Brain-inspired Intelligence Research Center Group." Shang Lu explained, "When I was in graduate school, I was in this department, and I studied the bipedal walking machine system under the control of the BCI system, and later focused on the harmless technology realization of the BCI system near the end of the human brain nervous system. ”

Chen Yu nodded as if he didn't understand.

At this time, he felt that the little chief engineer was from outer space.

They are all the same age, and he can only be an ordinary staff officer of the Operations Section of the Headquarters, but the small chief engineer is unfathomable - he only scolds his mother when facing Riemannian geometry and general relativity.

"You know that drivers rely heavily on the BCI system to operate giant machines and fight against angels, but invasive BCI can cause serious damage to the driver's brain, and the more you use it, the more damage it gets, so that there are uncontrollable consequences." "Our group's original goal was to find a new way to abandon the invasive BCI and find another way to test a non-invasive, completely harmless BCI system for drivers, the Deep Magnetoencephalography Neural Interface System, also known as MEG-BCI," Shang said. ”

"The result?" Chen Yu asked.

"A complete failure." Shang Lu replied, "The Institute of Automation was the first institution to carry out the research and development of the BCI system, and it was also the first institution to abandon the non-intrusive BCI system, because the non-invasive BCI system could not meet the requirements at all. The Rabin-Shang number of the BCI system can only be used against the angels if it is less than 0.12, and everyone must make the Rabin-Shang number lower than 0.12 within this framework...... To be honest, I have never been clear about what this standard represents, only that this is the bottom line, and now I finally know, it represents whether the driver can perform a wide phase theory calculation of EEG signal recognition and processing accuracy. ”

"I tried my best, the MEG-BCI system has never been able to break through the red line of 0.12, the accuracy of non-invasive BCI is too low, it is impossible to accurately capture the abstract thinking of the brain through the skull, brain tissue and scalp, in fact, when I joined the group, no one in the entire institute was engaged in the research of non-invasive BCI, everyone felt that this was a dead end, and they all tacitly agreed that they could only exchange the lives of the driver for the lives of all mankind." Shang Lu continued, "Only I don't believe in evil, I think I will be able to build a general model and find a way to get the best of both worlds, without harming the driver, and achieve the 0.12 standard." ”

Shang Lu paused and sighed.

"But how can there be such a good thing in this world?"

"Little Chief Engineer." Chen Yu said, "You have worked very hard. ”

"Of course I worked hard, I tried my best, I found a lot of people to be volunteers, to analyze the magnetic signals of each of their brains, the construction of the MEG-BCI system is much more complex and difficult than the invasive BCI, because the signal is weak, the latency is high, the signal-to-noise ratio is low, and the algorithm used has to be sharper, but the brain is really too elusive...... Everyone is different, they all think differently, and if this is an equation, then there is no solution to this equation at all. Shang Lu said, "I just spent a long time looking for a solution that didn't exist, until the whole group was disheartened." ”

Chen Yu didn't dare to speak, he was just a weak and ignorant swing.

Shang Lu put all his notebooks in order and dusted them off.

"Since you're already disheartened, why did you bring these materials over today?"

"Because the gods and Buddhas are blessing Shen Jiang." Shang Lu replied.

Chen Yu was stunned for a moment, not understanding what this meant.

"Because Jesus Christ, the Buddha, the Jade Emperor, and the Immeasurable Heavenly Venerable, are blessing Shen Jiang, that's why she is so lucky to meet me! The only person in the world who hit his head against the south wall! Shang Lu sneered, but his smile was a little bitter, "It is impossible to find a solution to this equation, and it is impossible for anyone to find a solution, but I will work hard...... You can find a special solution for her that only suits her! ”
