Standing in place, Thomson looked up at the sniper with a high posture, and then at Yang Lei, who was bending over and mopping the ground, couldn't help but shake his head, and sighed, it seems that it was a mistake to bring this guy here today, he believes that if the Holy Garden is also like the other four major powers, adopting a system of allowing students to learn freely and relaxing their management, then Yang Lei is definitely a well-deserved scourge!

"Teacher, it's all cleaned" Seeing that Thomson was still angry, Yang Lei was obedient this time, and said obediently: "The windowsill has been wiped three times, and the ground has been taken off twice, and there are no dead ends in all directions of 360 degrees, which is guaranteed to satisfy you!" ”

"Humph!" Thomson didn't believe it, he wouldn't be fooled a second time for this slippery head, and then inspected the entire laboratory, including behind the door and in the corner of the wall, it was really spotless, and he saw Yang Lei's hateful face again, which reminded Thomson of an old saying in Huaxia.

If you know today, why bother in the first place.

After the acceptance was completed, Thomson picked up the torque wrench in his hand and began to walk slowly towards the sniper, standing on the ladder, facing its engine and not knowing what was being tinkering.

"Hand me a hex flange bolt!"

Hearing Thomson's words, Yang Lei ran to the tool table, found a black thumb-sized bolt, and handed it to Thomson, now he is too late to please the tutor who plays a vital role in the final exam, looking at the attentive Thomson, and then stammered: "The teacher's technique is very skillful, the teacher's serious work looks so manly, the teacher ......."

"Get out of here while you're talking!"

"Teacher...... What I'm trying to say is, you seem to have twisted a little bit more......"

Thomson ignored Yang Lei, who was entertaining himself, and quickly turned the torsion plate in his hand, and Shuo was angry: "You kid is sharp-eyed, and he seems to know how to count, but, unfortunately, I tell you that you miscalculated!" ”

"Twist the triple buckle to lock the bolt, send the half buckle to flow out of the buffer space, if I'm not mistaken, the jitter and abnormal noise that this sniper made when it starts is because his designer took two and a half mouths at the time, so it fell off in a long time of jolting and vibration......"

"Mecha dynamics?"

"You know?" Thomson was a little surprised, because Yang Lei said the wrong thing just now, he thought that he had no training in this area, but it is no wonder that mecha dynamics is a knowledge point that the maintenance department will talk about in the next academic year.

"Since you know mecha dynamics, then I'll rely on you to ask a few questions, if you can answer them, we'll write off today's matter, and I'll give you permission not to take the final exam for this school year, how about it?" Thomson also wanted to know how much ink was in the stomach of this student who had been buried in the sea of people, only the old principal Konstantin had discovered.

"I want to try" Hearing Thomson say that he could be exempted from the exam, Yang Lei suddenly came to his senses.

Seeing that the other party was stimulated by his own success in learning, Thomson shook the wrench in his hand slyly and asked, "What is this thing called?" ”

"Torque wrenches, also known as torque wrenches, torque wrenches, torque adjustable wrenches."

"Hmm, barely qualified, listen up, my next question is, how many types of torque wrenches can be divided into, and what is its purpose?"

"There are three types, according to the power, they are electric, hydraulic and manual, and the hand torque wrench is divided into preset, dial and digital display."

"The main feature of the torque wrench is that the torque can be set, and adjusted according to the size of the torque required, mainly used in all kinds of mechanical maintenance, such as fastening bolts, generally for the fastening of high-strength bolts must be first tightened and then finally tightened, that is, the first electric wrench is locked to a certain extent and then the process of detection with a torque wrench, and each step needs to have strict torque requirements, like the hexagonal flange bolt held in the teacher's hand, this method must be used......"

Looking at Yang Lei intently, Thomson's eyes slowly changed, and finally asked, "Having said so much, will you use it?" ”

"Used."

"Will it or won't?" Once a fair federal soldier, Thomson hated this kind of ambiguity, which felt like a perfunctory statement.

"Yes!"

"Come up and try it." Thomson spontaneously cleared the space to the side, eager to see if this guy with no hair on his mouth was bragging after all.

Yang Lei did not hesitate, stepped on the ladder, took the torque wrench in Thomson's hand, and then demonstrated.

He held the sleeve in his hand, using the unique technique that Asimov had told him before, his right arm gradually strengthened, twisted three and a half times, only to hear the wrench make a crisp click, and soon fixed the flange bolt to death, and finally marked it with red oil, the whole process, Yang Lei's posture is standard, the technique is skillful, and outsiders can see that he is a veteran at a glance.

"Boy, who did you learn this bolt twisting technique from?" Thomson asked in amazement, for such a unique technique quickly reminded him of an ace technician who had disappeared from the Federation two years ago.

Hearing Thomson's words, Yang Lei was not happy at the time, thinking, what is stealing, it is obviously above board, and besides, he didn't want to learn it when Asimov taught him before, but now it seems that this is really a practical technique that can make people impressed.

"One...... Strange old man with raunchy lines! ”

"Konstantin old school?" Thomson said to himself, but it's not right to think about it, Konstantin's daily living habits are very checky, and it doesn't look like Yang Lei is raunchy as he said, he knows that Yang Lei is fooling himself.

"Since you don't want to talk about it...... Then I won't ask, but I think it's a bit too simple to get the exemption qualification at the end of the year just because of this" Looking at Yang Lei's gritted teeth, Thomson showed a sly smile, little ghost, I want to play Infernal Affairs with me, and I am still a little tender.

"Well, I won't embarrass you, as I said in class, this sniper is now facing a problem that produces jitter and abnormal noises when the engine starts, as long as you fix it, I will let you pass the annual exam!"

"Is that true?"

"I testify against my personality!"

"Cut...... Personality is worth a few bucks. ”

“……”

"Okay, it's a practical lesson in advance" Yang Lei got down the ladder, looked at the sniper covered in crimson paint, and said: "It's a pity to have such a beautiful mecha, it's better like this, if I really fix it, how about borrowing me to play for two days?" ”

"Heroes see the same thing, a good mecha should be galloping on the battlefield, not quietly sitting in a corner waiting for mold, if you can really fix it...... According to what you say, this is just the way to go. ”

Thomson's eyes lit up with a special emotion, and looking at the sniper reminded him of the thrill of piloting the mech in the Storm War, only after undoubtedly seeing the metallic mechanical arm......

Taking a deep breath, he said to Yang Lei firmly: "I think with my qualifications, I can apply to the school for your temporary ownership of this AB01." ”

"A gentleman's word?"

"It's hard to chase a horse!"
