There is a mechanical exoskeleton in the metal cabinet, the mechanical exoskeleton is also known as the power suit, which is the same series used in the special operations training base at that time, it is a more advanced version, this mechanical skeleton is very complete, equipped with a power unit, which can enhance the strength of the soldier's limbs, and give a certain degree of joint protection, in addition, due to the complexity of the military environment, this skeleton has an expansive design, which can be equipped with machine guns and telescopic bayonets in both arms, and can even be equipped with missile weapons on the back, and the head can expand communication equipment. At the cost of sacrificing a certain degree of joint flexibility, the lethality can be enhanced.

Ning Fei likes this kind of mechanical skeleton very much, and he often wears the one without a power unit in the training base at that time, because wearing an exoskeleton will make people feel safe and will not easily hurt themselves, after all, it is a mortal body. The structure of the mechanical exoskeleton and the control principle of the power device are not complicated for Ning Fei, if it weren't for the inconvenience of his legs, he really wanted to try it, and he didn't know how much gap there was between him and the super soldier after wearing the complete mechanical skeleton.

Ning Fei smiled bitterly at himself, it would be good if he could stand up again, what else did he want to do so much.

Ning Fei continued to look at other equipment, there were all kinds of pistols, the most delicate one, only the size of a palm, probably specially made for easy carrying, in addition to a sniper rifle, as well as a miniature homing missile, which could be equipped on a mechanical skeleton, and some laser-cut weapons, similar to a simplified version of the one in Kevin's hand.

There was also a helmet with a bulletproof mask in the corner of the box, Ning Fei reached out and took it, pushed up the transparent bulletproof mask, folded the mask into the top mezzanine, and put the helmet on.

Nimfer pulled down the mask, and suddenly an electronic sound came from his ear, the helmet system activated, and the transparent bulletproof mask showed an augmented reality interactive interface, showing a series of prompts - "The system is not matched to the mechanical skeleton", and many functional modules on the interface were disabled, except for the communication module available. This helmet is a control system, the control method is still relatively traditional, it is voice and gesture control, Ning Fei is a little interested in this system, so he casually looked at it, in addition to the communication module, there are also aiming, machine gun shooting, missiles, power adjustment, arm weapon switching, detection and other functional modules, but because they are not put on the mechanical skeleton and the corresponding attachment device, they are all in an unusable state.

Ning Fei wore a helmet and sat in the study for a while, until he began to feel sleepy, a little drowsy, and wanted to take a nap.

Exhausted, he closed his eyes.

After sleeping for about six or seven minutes, it can only be said that he was a light sleep, and there were many complicated illogical pictures flashing in his mind from time to time, if Dr. Wiener knew, he would probably think that this might also be one of the sequelae of brain trauma, and then Ning Fei suddenly shook his whole body, and suddenly woke up from the shallow water, his heart fluttering.

He took off his helmet, looked at the mechanical exoskeleton in front of him, and suddenly thought of a possibility.

Mechanical exoskeleton can give additional help to the limbs, mainly relying on the supply force of the power device, so if you design a control system to dynamically adjust the size of the auxiliary force, you can make your legs with dyskinesia, regain the balance of the limb strength, your legs with the assistance of this system, you can regain motor function through activity training, just like adding a mechanical prosthesis to the paralyzed, the metaphor is not very auspicious, the principle is similar.

I don't know the effect, but I have to do something!

Ning Fei took out the phone and called Caitlin, and the phone was quickly connected.

"Caitlin"

"Ning Fei? You're awake! Caitlin was surprised on the other end of the phone.

"Yes, it's me."

"We thought you were ...... How are you now, have you recovered? Caitlyn asked.

"I'm ...... now Well...... To make a long story, I had a long dream after falling into a coma, and then I woke up to find that my injuries were healed, but I couldn't walk, and then the brain surgeon said that everything was fine with my body, maybe there was a psychological problem...... I know this statement is a bit ...... mess", Ning Fei replied quickly.

"It sounds messy, is your head really okay?"

Ning Fei paused for a moment and sorted out his thoughts, "I'm fine, but I need your help, Caitlin. ”

"No problem", Caitlyn said without hesitation, "what needs to be done?" ”

"Listen to me, here's the thing, I need to build a device now to help me walk again, I need some repair tools for mechanical exoskeletons, I should be able to find the corresponding toolbox in the base, as well as circuit welding tools, and then I also need a computer, almost first", Ning Fei thought for a while, and added: "If you have time, help me bring a bento, the takeaway service won't work here." ”

"No problem, what flavor do you need?"

"Whatever, just don't be spicy."

"Wait for me for forty minutes."

......

Caitlin's professional habits lead to a really precise concept of time, forty minutes, no more than a point, no less than a point, neat and tidy, never dragging the mud and water.

Ning Fei was inconvenient to move, and watched Caitlyn move everything to the study, expressing her gratitude.

After Caitlin put everything away, Ning Fei was really hungry and devoured the bento.

"Bento 50 yuan, remember to transfer it to my account", Caitlin casually handed the bill to Ning Fei, she was attracted by the contents of this room, and walked to the metal cabinet behind the bookshelf.

"Uh, of course, I'll pay you 500 yuan, no, 5000 yuan, thank you for reaching out!" , Ning Fei didn't raise his head with food in his mouth.

"Come on, you don't have that much money."

Caitlin wasn't particularly surprised to see the weapons in the metal cabinet, after all, the weapons she was using were top-notch in terms of power and technology. But when the eyes swept over the delicate pistol, it was still a sight to behold, delicate and beautiful things, which women liked.

"That gun was given to you, it suits your temperament very well", Ning Fei said in the back.

Caitlyn picked up the gun, loaded it with a magazine, held it in her hand, opened the safe, and searched the room for objects to aim.

Ning Fei hurriedly put down the lunch box to stop it, "Don't don't, this is already a family with four walls, go back and find an open place to try again!" ”

"It's very good, your bill is cleared."

Ning Fei wiped his mouth after eating with his sleeve, opened the bottled sparkling drink that came with the bento and took a sip, it was really comfortable, and said to Caitlin: "Help me take out that mechanical exoskeleton, just put it on the table, and the laser cutting device on it, I can't reach it." ”

After Caitlin helped Ning Fei put all the things he needed to put them in a convenient place for him to reach, Ning Fei began to disassemble the mechanical skeleton, dismantling the parts of the two arms, and also dealing with some components for attack, and the weight of the entire mechanical exoskeleton decreased. The back of the exoskeleton is loaded with a high-performance battery pack, the design of this battery pack also has certain hidden dangers, once it is hit by a bullet or violently impacted, it is easy to cause deflagration, and the wearer is injured, Ning Fei does not need to carry an explosive package in the back, nor does he need so many high-performance batteries, so he moved part of the battery pack to both sides of the mechanical parts of the legs, even if an accident occurs, it is only a local battery deflagration, and the damage is limited.

The whole extra-machine skeleton, in fact, Ning Fei only needs the waist and legs to provide limb assistance for the legs, all unnecessary components are carefully removed, the hips, knees, ankles and other positions in the leg components are equipped with sensors and micro permanent magnet motors to detect limb behavior and provide positive and negative power, now these positions are needed to work independently, so Ning Fei also disassembled the helmet, he does not plan to wear a helmet to control how to walk on his legs, this is of course also feasible, but it seems too stupid, human beings only have one brain, But machines can learn to think with each part.

The night was already very late, and Caitlyn didn't know when she would go back to rest, but Ning Fei was still in high spirits, talking to herself while keeping her hands busy, maybe she had slept too long in one breath.

"The control system is back up, and now it's time to perform the craniotomy," Ning Fei patted the helmet on his hand.

"Cheer up, some music!"

......

The night sky of the base was already glowing, and it didn't take long for it to turn white, and the slogans of army training came from the window.

The computer is connected to the control board of the modified mechanical exoskeleton with a cable, and the modified control system is rewritten.

That's it!

Ning Fei turned on the mechanical skeleton, and the system operated normally.

"Well done, I'm a genius!"

"Knock knock knock ~ knock knock ~", there was a knock on the door outside.

Before Ning Fei could open it, the door was pushed open from the outside, and Caitlin walked in, holding breakfast in her hand, and said angrily, "I guess if you didn't hear it, maybe you died suddenly." ”

Ning Fei was happy, so he didn't care, and excitedly beckoned Caitlin to see the results of his work.

"So...... You made a pair of high-waisted iron pants all night long? Caitlyn propped her hands on the table and looked closely at Ning Fei's handmade gear, "Not to mention, this insulating tape is tattered and tangled in a punk style." ”

Ning Fei waved his hand, "Don't say that, it's just a little ugly, as long as it can be used at the moment, quickly, help the handle, I have to put it on and try this device." ”

Caitlyn helped to put on this half-body mechanical exoskeleton, although Ning Fei's legs were inconvenient, but fortunately, Caitlyn had a lot of strength, and it was easy to wear it.

Seeing Ning Fei standing up smoothly in a half-body exoskeleton, he couldn't help but admire, "This paralyzed booster machine is not bad." ”

Ning Fei adjusted the strength of the power assist parts and the sensitivity of the joint sensor, and when he was ready, he exerted force in his legs and walked forward, the leg strength was still smaller than expected, but Ning Fei felt the positive power from the mechanical bones, and then stabilized, and then raised his other foot, and suddenly used too much force, Ning Fei panicked, but the mechanical bones sensitively exerted a reverse resistance, Ning Fei stood steadily, and said with a happy smile: "Works normally, genius idea!" ”

Ning Fei suddenly felt a sudden impulse in his heart, raised his legs to speed up, continued to walk, turned back, and began to run.

One step, shaking slightly.

Two steps, steady.

Three steps, gradually speeding up ......

"Bang! Whoa~", Ning Fei stepped on a small part and fell to the ground, covering his head in pain.

Caitlyn rolled her eyes helplessly, as if she had expected the consequences of Ning Fei's death a moment ago, "You really shouldn't have removed the helmet." ”
