Click, holding precision tool pliers, Chu Han, who was wearing goggles, was holding tweezers and carefully placing the last chip.

"The eight tentacles should be branded with an ultra-high voltage arc, and the arc welding machine should also work."

Casually sliding on the virtual screen on the right side, Chu Han retrieved the method and steps of arc welding, and lifted the welding torch with his right hand.

The blue arc was mixed with high-heat sparks, which burst from time to time, and a burnt smell soon filled the air, and the lights in the bedroom became flickering and dimming.

That's right, this scene of "sparks with lightning" was made up by Chu Han in the bedroom.

(The student dormitories of the college are generally four-person or six-a-side, and Chu Han and Huang Yuan occupy a dormitory)

Boom! The door suddenly opened, and the alloy door slammed against the edge of the wall with a loud noise, and Huang Yuan, who looked like a small mountain, leaned sideways and squeezed in from the door frame.

The cold muffled sound frightened Chu Han's body, and the tip of the welding torch drew an "S"-shaped arc directly against the chip, and those fine conduction wires were directly scalded into a lump by the high temperature, and the things that had worked hard for two or three days were scrapped instantly.

"Holy! Huang Yuan, I'm fighting with you! ”

Ten minutes later, Chu Han, who had vented his anger, sat on the edge of the bed decadently, took off his glasses and rubbed his eyebrows.

After straightening his hair like a chicken nest, Huang Yuan stepped forward with a dead face and grabbed Chu Han's shoulder.

"I said glasses, why don't you go to the shooting range to practice guns, what kind of welding are you tossing in the dormitory, don't forget that Teacher Chen Chen also set a goal for you."

Hearing Huang Yuan mention the words "practicing guns", Chu Han suddenly felt extremely bored in his heart.

"Alas, I'm worried about this now, for two months, even if I don't sleep, I can't guarantee that I can practice a 90% hit rate of the kilometer target. I don't think Mr. Chen Chen's words are as shallow as they sound on the surface, and half of the books he listed for me are about gun modification, and many sniper masters are themselves mechanical masters. ”

"You mean, you can use a modified gun to shoot targets, damn it, that's the idea."

"Stabilizers, calibrators, clamping or something are easy to do, just lack a smart chip, although I can write a capture program, but the hardware can't do it, and finally get a semi-finished product, and it will be destroyed by you at once!"

"Hehe, buddy didn't mean to, but I also have to criticize you, isn't there a god of the Armament R&D Department living in the 578 dormitory, you invite him to a meal, what hardware can't be done?"

Chu Han: "......"

————

"Are you sure this is the Headmaster's Office?"

Chen Chen, who was dressed in civilian clothes, carried Ru Yan and glanced murderously at the young man next to him, who suddenly felt a chill on his neck.

"This is indeed the principal's private study, but it looks a little 'retro' on the surface......"

As the assistant principal, the young man's words are very subtle, what kind of retro is this, it is clearly ancient!

The paint on the lintel is dry, it seems that it has never been renovated, and the corridor is lined with alloy walls on both sides, but in this study, it is still an old kiln brick.

"It's Teacher Chen outside the door, please come in!"

Through the yellowed wooden door, an old and gentle inquiry came from the room, and Chen Chen no longer hesitated, and pushed the door directly.

The expected brightness and grandeur did not appear, and the study looked a little cluttered.

Thick curtains are tied in front of the floor-to-ceiling windows, half-unraveled and half-opened, making the light source a little dim. On the left-hand side is a bookshelf with a number of books on history and language; On the right-hand side is a shelf with a dazzling array of strange things.

There are swords in the cold light, rum with green hair, shells and stones picked up from the seashore, and exquisite starship models......

In the center is a quaint desk, and not far from the desk is a leather sofa, on which a thin old man in formal clothes sits with a cane leaning against him.

"Headmaster, Mu Tianxing?"

Haha, the old man looked up and chuckled a few times, and patted the sofa cushion in front of him with his hand.

"Isn't it like that, let's sit down and talk first!"

Chen Chen sat down in front of the old man as he said, and Ru Yan was still holding it in his hand.

- "There's no need to get into tension, Instructor Chen has actually been in contact with the two of us. ”

"Ao, why doesn't Chen have an impression?"

- "On Tianxun, that is not an auxiliary public account, but my personal account, you ask me for a map, recovery liquid..."

"Hmm... This is not the key to Chen's coming to you, I think you should tell me what I want to know. ”

Chen Chen's words paused a little, he really thought it was the official account before, and he sent a request to ask about it, but the other party responded vigorously every time, and then left him a string of "ellipses".

No wonder, the headmaster's instructions, does the academy dare to delay? That's really the reason when you think about it.

"Okay, since Instructor Chen wants to hear it, then I'll tell you what I know. More than half a century ago, the Dark Star Domain was recovered by the Federation, but in fact, it was only a nominal recovery, and there were still resistance forces in many places. There are empire-run rebels, rebel armies in the Dark Star Domain, and even some underworld forces. ”

"The turmoil lasted for a decade or two before it was suppressed one after another, some were eliminated directly, and some were pacified, and in order to maintain stability, the Federation signed a memorandum treaty with these people, promising to exchange high-ranking officials for peace. This is also the reason why the quality of officials in the Dark Star Domain is uneven. ”

"In the past few years, the exploitation of the Dark Star Domain has become more and more serious, the lives of the civilians have been difficult, and with the bewitchment of people with good intentions, rebellions and uprisings have emerged one after another. In fact, Instructor Chen should also know that the military funds allocated by the Federation to the Dark Star Domain are a little reluctant to even maintain stability, let alone suppress the rebellion. ”

"Therefore, this requires the wealthy businessmen and crocodiles to donate money and efforts, and the army is slowly infiltrated by other factors... After that, the old man didn't have to explain. ”

After the old man said this, he shook his head helplessly, he didn't explain why Mu Xue was able to mobilize the army, but told Chen Chen the truth from the root.

He admires Tianxing, in fact, he is just one of them, there is nothing unusual.

"Speak of illegal things as a matter of course; Blame the exploitation and oppression of officials on the rebellion of the civilian population! Mu Tianxing, do you think Chen won't dare to kill you? Or do you think Chen is ignorant of the world? I just want to hear one thing today, who exactly is behind all this! ”

The situation in the Dark Chen Domain was treacherous, the old man couldn't help but say it too simply, Chen Chen's intuition told him that the truth of the matter could never be so simple.

"Instructor Chen, do you think I'm behind it? The old man is half of the earth, how can he-"

"But you are not old-hearted, you have been the speaker of the Canaan Star for three terms, and the current Murong Executive is your junior, I will give you one last chance to confess everything!"

The knife was unsheathed, and Chen Chen, who had a fierce expression, had unabashedly released the killing intent in his heart. In his opinion, everything about the old man was a posturing and an attempt to cover up the truth of the matter.

The room was as silent as water, the principal closed his eyes and thought about it for a long time, although Chen Chen was young, he felt extremely tricky, as ruthless as a wolf, and he would not give up until he pounced on his prey.

"There is a rebellion on planet Dylan, and the rebel leader Auroris Sjie was a pawn of that man, and he is demagogic with the situation of a cult, get rid of him, and you will get the clues you want. I'm really tired of it, old man, but I can assure you that the Canaan Star will not be the same as yesterday. ”

The old eyes looked directly at Chen Chen, without any waves.

"I'll check it out, if you lie to me-"

"Take those five students and let them go through the experience too. If things are false, it is up to you to kill or chop them. ”

......

In the afternoon - shooting range, Chen Chen stood behind Chu Han and watched him calmly knock down the targets one by one.

Forty-six bullets hit 44 thousand-meter targets, which is already a terrifying hit rate.

"With the addition of a sight glass, the distance between objects has been shortened, and the talent is amazing, and the courage is careful!"

Secretly muttered in his heart, Chen Chen had never given people such high praise, Chu Han was definitely the first.

"Well done, I did read the book I gave you, but I promised to give you a few days later in the gift. The college arranged a trip for us, you go back and pack up and leave in the evening! ”
