Department of Maintenance, Class B.

At this time, two minutes have passed since the class, and in the sacred garden with a strict education system, the students have already returned to their positions, waiting for the arrival of the teacher, but now even the teacher who is lecturing is in place, but there are still students who have not entered the class, looking at the man on the podium who is about to go crazy, everyone can't help but sweat for Yang Lei.

Thomson, that's right, the first time the students hear his name, they will think of the domineering heroic weapon in the shooting game, in fact, in the Storm War, Thomson, who served as the senior technician of the 38th Mechanized Brigade of the Federation, is like a fierce dragon on the battlefield, although he can't manipulate a powerful mecha to kill the enemy, but if there is a problem with the Allied mech, he will definitely be the first to rush to the front line.

In the eyes of ordinary people, the mecha maintenance division is more like a logistics force, in fact, take Thomson's lost arm as an example, after getting the information that his comrade-in-arms mecha is short of energy, he rushed to the front line to deliver the energy core and was bitten by a mutant beast that suddenly attacked.

Looking at Yang Lei standing at the door, Thomson's eyes had a hint of suspicion, and then he was relieved. The regulations issued by the old principal Konstantin have all been read by all the teachers in the school, how could Thomson not know that Yang Lei is the late auditor. Moreover, after the last time he fought with this kid, his left arm still has a dull pain sometimes, and the damage of the dark energy is really great!

He thought that maybe this Huaxia kid could surprise him again in this maintenance class.

The next moment, after seeing the scarred face who was not smiling on weekdays, waved his hand lightly, and motioned for Yang Lei to take a seat, all the students showed incredible expressions, even Thomson was so polite to him, it seems that this new backstage is very hard!

Similarly, in order not to disturb others, Yang Lei chose the position of the last row, but despite this, the students in front couldn't help but move quickly to the side, for fear of being stained with this plague god covered by the principal.

Seeing this, Yang Lei was quite helpless, but soon, he noticed an obscene figure next to the trash can.

"Watt...... Watt......"

Yang Lei didn't expect that Watt, who looked weak on the outside, would dare to sleep openly in class, and after kicking him awake, the two of them then became embarrassed, staring at Thomson on the podium, and he was looking forward to what the man would say next.

"What's the origin of his arm?"

At the beginning of the lesson, Thomson gently raised his right arm, grabbed the chalk, and wrote on the blackboard, the font was sonorous and powerful, very standard, but in this case, the metal arm in his sleeve was undoubtedly exposed to the air, and everyone had long been surprised by this.

"Oh, the bionic arm, controlled by the mind, do you know the brainwaves? After the spinal cord implant, it's really no different, at least tying your shoes, and pulling the zipper of your pants is not too difficult, you know......" Watt let out a smirk.

"Thoughts?" Yang Lei muttered to himself, could it be that this Thomson is also a spiritual powerhouse? He focused his eyes on the black bionic arm again, quietly took out the heavenly news from his pocket, and while Thomson was not paying attention, he tracked and filmed the mechanical arm, and then put it in the palm of his hand to search for this information.

With the continuous development of federal science and technology, bionic technology is also growing rapidly, bionic arm, that is, the prosthetic limb in the mouth of ordinary people, its main role is to replace part of the function of the lost limb, so that the amputee can restore a certain degree of self-care and work ability, to a large extent, this makes people who lost their arms due to illness or accidents see hope, and regain their lives, such as Thomson in front of him, one of the most powerful bionic arm owners in the world.

The power of this robotic arm with nerve grafting technology is that it is no different from an ordinary person, and it is controlled by his own brain. Signals from the human brain move to the nerves in the upper arm, driving muscle activity. The motion sensors inside the robotic arm then trigger a mirrored human action through the detected activity.

For now, the state-of-the-art bionic arm has a total of fourteen preset movements, including tying shoelaces and pulling drawers.

Some of the robotic arms can even play the piano and pinch coin-sized objects with ease, which is why Thomson was able to write a beautiful board book even after losing his arm.

In addition, the bionic arm is made of stainless steel and titanium alloy, which can enhance the firmness of the momentary force, and of course, it can also be covered with a more realistic silicone skin, but Thomson does not deliberately disguise his shortcomings.

Every time he calmed down and saw the metallic sheen on his mechanical arm, all the things on the battlefield in the past would come to mind, and he thought that it was an honor, just like the scars left on his face from the fight with the mutant beast, which looked ugly to outsiders, but it was a medal that belonged to a warrior!

Despite this, the bionic arm still can't let him do whatever he wants, but it is more than enough to deal with the current daily life, and this bionic arm does not cost him a penny, it is completely tailored for him by the most famous design master in the federal bionic world, which is a kind of tribute to this veteran who retired from the front line.

"Wow wow wow...... The latest Tianxun, a high-tech product, Yang Shao, this must be the rich woman who gave it to you again, borrow me to play for two days! Watt looked at the triangular sign in Yang Lei's hand, as if he remembered something, and whispered: "This shouldn't be given to you by the little princess, right?" ”

"Noise." Ignoring Watt, who kept chattering, Yang Lei looked at Thomson's tall figure on the podium at this time, as if he felt much greater than Iron Man!

"Today's federation is becoming stronger, maybe our predecessors never thought that this planet could develop to this point today, the mecha civilization has become more and more mature, just like the car before the storm war, therefore, our maintenance technology is also getting more and more attention, okay, please open the thirty-eighth page of the mecha basic maintenance manual in your hands......"

Ten minutes before the end of class, Thomson clapped his hands and signaled everyone to be quiet, and then took out an irregularly shaped abandoned engine from under the lectern, and said: "This is an abandoned engine that is too noisy when starting, and there will be strong shaking, due to time constraints, I will not ask you to troubleshoot and fix this, but the first step to fix the engine failure is to take it apart, so I want to see everyone's hand speed......"

"This is also the class assignment I gave you in this maintenance class, who will try it?"
