Yu Ren traveled from the barracks to the Ninth Living Base, which is the Federation's farthest base on the alien planet from the frontline battlefield, and from this point of view, the Ninth base is the safest place on the alien planet.

In order to become a mecha warrior, Yu Ren paid a lot, and for this he even risked participating in unknown experiments. Actually, he didn't think it was really risky, after all, it was just an experiment to make him a mechwarrior.

But when he actually came to the experimental site of Base Nine and saw all the people who participated in this experiment like him, he knew that this experiment was very risky, because all the people involved in this experiment were not mecha warriors.

It's normal not to see the special and first grades, they don't need this kind of experiment to improve the ability to operate the mecha at all, but many level 2 and 3 mech warriors do. To be reasonable, let the second- and third-level mecha warriors who can fly mecha themselves participate in this experiment and improve their strength, then the Federation will definitely be able to increase many first-level mecha warriors in a short period of time, and many of them will be promoted to special grade.

But there wasn't a single mecha warrior in the test site.

"Corporal Yu Ren, your number is 927."

Are you the 927th person to participate in the experiment? Yu Ren didn't see so many people in the laboratory area, there were only about three or four hundred people, and so few of them were people who had participated in the experiment before, or had they already been ...... because of this experiment

"Okay."

Yu Ren, who had completed the physical examination and changed his clothes, was led by the relevant personnel to a room-like room, with a large area, about fifty beds neatly arranged, and some of the beds were already lying on the same subjects as him.

The clothes they wore were very similar to the hospital gowns, completely different from the uniforms they normally wore in the base, each of them had a plastic bracelet on their hand, with only their own number on it and no other function, and the communication bracelet had been taken away.

"927, please lie down."

According to the instructions, Yu Ren lay on a bed, and next to him there was more like a doctor than a researcher, took out a bottle of saline-like medicine from the cart next to him, and began to hang the needle on Yu Ren, who was not suffering from any disease.

Yu Ren, who was looking at the hanging bottle with his eyes open, soon fell asleep with sleepiness, and when he woke up again, he felt that the back of his neck was cold, and when he subconsciously reached out to touch it, he was stopped by the person next to him.

"Don't touch it yet, because it hasn't grown with your flesh yet, and the touch will make you feel pain, which in turn will affect your nervous system, and the most serious consequence is paralysis of the whole body."

Yu Ren's movements froze, and he looked at the white coat beside him with some horror.

"Don't be nervous, you have safely passed the most dangerous phase of this experiment, and we have tested it, and your adaptation rate is very high, which is unexpectedly high." The white coat looked at Yu Ren and said with a smile: "Please come with me." ”

Yu Ren got up, and his movements were not affected by anything more on the back of his neck, except for the cold feeling, as if nothing had changed.

In the process of leaving the ward-like room, he finally saw what was on the back of his neck, and how it came from.

Not to see the back of his own neck, but to see the back of someone else's neck.

On a hospital bed that passed, the person who fell into anesthesia, his body was fixed by a restraint belt, and the illness was flipped under the operation of the person next to him, and a gap appeared at the bottom of the bed, revealing the back of his head.

After shaving his head and disinfecting, an intelligent robotic arm slowly pressed on the back of his head, leaving behind a round metal device like a chip, about five centimeters in diameter.

"Don't be nervous, this stage is very risky, but so far it has not caused anyone to die."

"What the hell is that thing?"

"Brain-computer interface."

The white coat that led Yu Ren was a native of Yingzhou, and when he led the way in front, he introduced it in a low voice.

"You've successfully installed the brain-computer interface, so you can learn more about this experiment. I will give you a general introduction, if you don't understand or want to know more details, you can ask questions after my introduction. ”

"Okay."

"The experiment you are participating in is Project Ares, which we commonly call the God of War Project, which is simply to create the most powerful mecha warriors and help us win this war."

The white coat paused slightly, and continued: "Its essence is to use neural link technology to drive the mecha, after the installation of the brain-computer interface, combined with the new mecha cockpit, theoretically speaking, there will be no more operational difficulties in piloting the mecha, and everyone can become a mecha warrior in the true sense." Because, when you enter the cockpit of the new generation of mecha, no matter what action you make, the mecha will make exactly the same action at the first time, and you control the mecha as if you control your hands and feet, and when you make non-standard tactical maneuvers, it is as easy as blinking your eyes. ”

Yu Ren was shocked: "It's so simple? ”

He has been training hard for nearly ten years to become a mecha warrior, but he has never been able to pass the relevant exams, and now he can become a real mecha warrior with just a brain-computer interface installed on his head?

It's definitely good news, but it's actually a bit bitter, because it means that his previous ten years of hard work don't make any sense.

"It's just theoretical." The white coat explained: "After all, the mecha is not a human body, because of the mechanical structure, many of the action mechas that we humans can do cannot be completed. When you control the mecha as if you are controlling your own body, the first thing you need to do is to maintain the center of gravity, which is actually very difficult, many people who participated in the experiment before could not do this, and when driving the mecha, they could not fight at all, and they would fall directly after taking a few steps. ”

"In addition, the mecha can also do some actions that our human bodies can't do, and if you can't get familiar with the mecha you drive, you can't give full play to the strength that the mecha should have. So, we want people like you to succeed. ”

Yu Renleng said: "People like me? ”

"Your nervous system is strong, which is a prerequisite for participating in the God of War program. Over the past many years, you have been working hard to train your mecha piloting skills, and you are familiar with almost all mecha standards in our Federation. Although you haven't been able to pass the exam, it only means that you are hand-disabled and not brain-dead, and now you don't need to use your hands to operate the mecha, so the hand-disabled is not a problem. ”

Hand crippled.

Yu Ren was slightly embarrassed, although the existing mecha driving methods, although using more intelligent technologies such as brainwave sensing and voice control, mainly relied on the control of the joystick and control pedal by hands and feet to complete the control of the mecha.

The flexibility of the hands and feet is very high, and because of the height of the mecha's viewing angle and the 360-degree viewing angle, the requirements for hand-eye coordination are also very high.

and so on, all of which are the reasons why Yu Ren's hand is crippled and he can't pass the exam.

"Then why don't you let real mechfighters participate in this experiment?" Yu Ren asked: "They must know more about mecha than I do, and they are used to piloting mechas, so it is impossible for them to be unable to control their center of gravity, or they don't know what actions the mecha can make and what actions they can't make." ”

"As I said earlier, a strong nervous system is a prerequisite and the most important condition." "Our mechwarriors are good, all excellent, but not all of them have strong nervous systems. Theoretically, they can all participate in the program, but in order to achieve better results, we have to go through a physical examination to determine the most suitable person, and this has to mention the word synchronization rate. ”

"Synchronization rate?"

"Yes, synchronization rate."

The white coat led Yu Ren through the two metal gates, constantly brushing the permission certification.

"The specific definition of the synchronization rate, you can understand it through the operation manual, I will briefly tell you first, it can probably be understood as: when your idea becomes the specific action of the mecha you drive, the time it takes to consume, and the accuracy of the action is comprehensively determined, the higher the synchronization rate, the better, if it can reach 100%, it is equivalent to completely treating the mecha as your body to operate, to use your favorite word in Longzhou people to describe, that is, the integration of man and machine."

Yu Ren probably understood, and asked curiously: "Is it possible to be higher than 100% synchronization rate?" ”

"How is that possible, the full score is 100 points, and you can still score 101 points?" The white coat laughed and said, "Don't say it's 100% synchronization rate, as long as you can achieve 80% synchronization rate, then you can really pass this plan and become a new generation of mecha warriors." ”

"80%?" Yu Ren gained confidence.

"Don't underestimate the synchronization rate of 80%, all of our experimenters who have reached the synchronization rate test stage at the moment have only achieved a synchronization rate of 86%. Most people have a sync rate of around 70%, and sadly, they're all screened out. ”

"Sifted out?" Yu Ren subconsciously wanted to touch the back of his head, but forced himself to stop and asked, "Then will this thing at the back of their head be removed?" Will there be a scar or a hole after removal? ”

At the thought of that kind of picture, Yu Ren couldn't help but shudder.

"It's not going to be demolished, because it really leaves a hole and it can cause nerve damage. At present, our technology cannot completely repair the damaged body and nerves, so this is one of the risks of this experiment. ”

Hearing this answer, Yu Ren made up his mind in his heart that he must pass the test, otherwise it would be too terrifying.

"But our brain-computer interface technology is still being studied, and this is only the first generation of products. If the research of the next generation of brain-computer interfaces goes well, according to our design, it will not be built directly into the human body, but will be attached to the back of the head like a patch. ”

"How long will it take?"

"If it goes well, a year or two."

"Then why not wait?"

"Because we don't have that much time left."

“……”

The two of them finally arrived at their destination, a very wide area, the most conspicuous of which were the six mechs parked in it. But Yu Ren was not brought to the mecha, but to an oval metal body, and there were sixty such oval metal bodies in this area, all about one meter and a half in height, with some wires and metal pipes connected to the perimeter.

"This is the new generation of mecha cockpit, you get ready, and you will go in and do simulation operation experiments later."

The white coat said, opening the oval metal hatch.

"Okay."

Yu Ren looked inside the cockpit, and his expression became surprised, because there was nothing in it except a helmet, and some of them were too short, and he couldn't stand up straight inside at a height of one meter and five.

"Once you're inside, put on your helmet, we'll inject a buffer, a special liquid that will improve your ability to resist overloads and mech impacts. The body should be curled up and you just need to think of a comfortable position. You need to be careful not to control your hands and feet, and focus on the control of the mech. ”

"Okay."

Yu Ren was ready to enter it, although it was only a cockpit, but he had used the second-generation simulation system many times and knew that it was a technology similar to simulated driving.

When the white coat was ready to be completed and Yu Ren was allowed to enter, Yu Ren suddenly thought of a question.

"Then if it's a peerless master like Lieutenant Ji Xinghe, if you use this driving mode, will you be able to fight hard? Mecha knows martial arts, and no one can stop it. ”

"Lieutenant Ji Xinghe?"

"That's right, it's the oldest special mecha warrior, he has a lot of kung fu and can fly mechas, this driving style is simply tailor-made for him."

"I've heard of him, and in theory this driving mode is really good for people like him, but here's the problem...... He is too old and his nervous system has deteriorated. We did experiments, and the best score of a person his age in the test was only 30%. ”

Yu Ren was stunned, 80% of the synchronization rate could not pass this experiment, and the 30% synchronization rate definitely did not have a chance to participate in the experiment.

The white coat continued: "After our experiment is successful, all the mecha cockpits will be gradually replaced, and you have to get used to this way of driving as soon as possible, because it won't be long before you become our main mecha warrior." Perhaps, you will become a new super, or even a new trump card. ”

"All? Replacement? ”

Yu Ren's mind had no conjecture of becoming a special grade or ace at all, and he thought of Ji Xinghe's explanation to him, which seemed to be a lie.

Ji Xinghe, as a super-level mecha warrior and a professional-level mechanic, is very likely to have known about this experiment for a long time, and knew that in the future, the cockpits of all mecha will be replaced with those that require brain-computer interfaces, and as a mechanic, he may even change the cockpit of his mecha by himself.

It's cruel.

Because after the replacement, Ji Xinghe can no longer drive the mecha. That's why he died asking for money, and his selfish reason to leave an inheritance to his granddaughter was just an excuse for him to continue piloting the mech.

"Is it possible?" Yu Ren, who was standing at the door of the cockpit, did not go in, but looked at the white coat seriously and said, "You arrange a test for Lieutenant Ji Xinghe, maybe his synchronization rate will be higher than you imagined?" ”
