Act-1

Bypassing the dilapidated cafeteria, following the path full of fallen leaves and mud, and passing through the new library, which has not yet been officially put into use, Jiang Tian and Ji Luo came to the front of the school's laboratory building.

Looking at this familiar and unfamiliar experimental building, Jiang Tian felt an indescribable feeling rise in his heart.

Wencheng Institute of Engineering as the province of the end of the crane of science and engineering, the faculty is weak, the source of students is not as good as the medical school next door, but, as the only university in Wencheng, the Municipal Education Commission still attaches great importance to it, millions of machine tools said to buy, tens of thousands of stress testing experimental equipment to buy is dozens of sets.

It is precisely because of the investment of the Education Commission and the school in these engineering equipment regardless of the cost that the school's machinery and mining majors can stand out in the competition of the surrounding cities and attract heavy coal engineering enterprises from this province or even other provinces to recruit talents here.

Walking into the basement of the laboratory building and coming to a diesel generator, Jiang Tian asked while fiddling: "Ji Luo, I don't seem to have asked you, which major are you a student in?" ”

"Department of Information." Ji Luo looked at Jiang Tian's face stained with diesel fuel after a while, so he took out a handkerchief from the pocket of his skirt and handed it to Jiang Tian, "Senior, do you want to wipe it?" ”

Jiang Tian shook his head, the movements of his hands did not stop, he said: "It's still early, when I finish this generator and turn on the electricity in the laboratory building, we will be able to manufacture some simple weapons." When the time comes, we will be able to go out safely with our weapons in hand, so that we can obtain some basic living resources. ”

Ji Luo nodded yes, Jiang Tian's choice was right, they had to obtain the living resources that could allow the two of them to survive. However, until then, they need to take something to defend themselves.

Now that the aliens have invaded Earth, their enemies may be everyone but them!

"Click, Click, Click, Click, ......Click, T

After a while, Jiang Tian successfully repaired and started the diesel generator with half of the fuel, and after connecting the lines of the laboratory building with the generator after the amplified voltage, the lights in the basement suddenly turned on.

"Okay, let's use these machines in the basement to make some simple weapons." Jiang Tian took the handkerchief handed by Ji Luo for the second time, wiped the dust and diesel stains on his face briefly, and then got up and walked to several machine tools more than one person high in the depths of the basement.

After going around and doing some simple debugging on the machine tools, Jiang Tian slowly breathed a sigh of relief: "Whew, fortunately, these machine tools are still usable." ”

And just as he was about to get some steel for a simple initial job, he saw two good things behind a fallen chair: "Huh? There's also an electric drill and welding torch here? That's great, I thought I could only make some cold weapons, and at most sharpen some blades, but now with these scrap steel and welding guns, it's enough for me to make a proposed perpetual motion axis. ”

"Perpetual Axis?" Ji Luo, who was helping to carry scrap steel, heard this term, his eyes lit up, and he said in surprise, "Senior, what you said shouldn't be a perpetual motion machine, right?" ”

Jiang Tian glanced at her with a smile and teased: "Let's not talk about the machine, civilized you, me and him." ”

"Don't be kidding, senior, tell me quickly, is it really a perpetual motion machine ......?" Ji Luo asked.

Jiang Tian nodded and said, "Well, indeed, but the output power of the perpetual motion axis made of these materials is not high." By the way, if you go to the mechanical principles laboratory, which is the laboratory on the second floor, take some gears down, and use these steel materials to make gears, the strength is too low.

Well...... Also, you walk around the dormitories to see if there are any things left behind such as power banks or data cables, if there are any, bring some back, if not, it doesn't matter, it can only be said that it takes a little more effort. ”

"yes, I see." Ji Luo wrote down what Jiang Tian needed in his heart, and quickly left the basement where the environment was noisy, dusty, and dusty.

Next, Ji Luo searched the campus over and over again for the materials Jiang Tian needed, and Jiang Tian skillfully controlled all the tools in the basement, methodically manufacturing the perpetual axis that this principle process had been deeply imprinted in his mind.

Soon, before the fuel for the diesel generator was about to run out, Jiang Tian finally made this black technology that should exist in fantasy...... Perpetual Axis!

It is a hollowed-out sphere the size of a football, through the void, you can see countless small gears floating and rotating in the air, and in the center of the gear wrap, there is a glowing ball of light that appears to be an energy body.

Although Jiang Tian said before that the output power of the perpetual motion axis produced would not be too high, after completion, the finished product slightly exceeded his expectations.

The instantaneous output power of this perpetual motion axis is about 110 kilowatts, which is roughly the output power of an ordinary car.

However, the Perpetual Axis can also be used as a bomb, and its explosive power is about the same as that of a TNT bomb of the same volume, and it is not much of a problem to throw it over and blow up a small six-story building.

It's just that I don't know if I can kill or blow up the defense of the so-called "demon", but, with the current conditions, in the same amount of time, Jiang Tian can't find a more useful device than the perpetual motion axis.

After all, it is a matter of probability that they go out and encounter demons, and because Wencheng is not valued by aliens, the probability of encountering aliens will be greatly reduced. Then, the perpetual motion axis, which can be used as a generator and a bomb, is the best choice.

"Senior, did you succeed?" Ji Luo wiped the sweat from his face and panted.

Jiang Tian smiled and nodded: "Well, it was successful." This is the perpetual motion axis, which can replace the noisy diesel generator as a clean energy source for our temporary activities around the school. ”

Ji Luo looked at the hollow metal ball that exuded a faint ice blue light that kept floating and changing positions at the center, and suddenly said, "That...... What about the weapons we use to defend ourselves when we go out? ”

Jiang Tian pointed to the perpetual axis and said: "I have connected some wires for energy output on its periphery, and when the time comes, we can connect the abandoned cars outside through these external wires, as a tool for us to travel, just right, its output power is about the same as the output power of an ordinary car engine, but if you travel on the road around the school, there will be no problem." ”

Ji Luo took a deep breath and looked at Jiang Tian coldly: "Senior, are you avoiding my question?" ”

Jiang Tian shook his head and said, "This is also our weapon, and if necessary, it can be used as a bomb." When it explodes, it will produce a shock wave and an electromagnetic storm, and as for the power of the explosion, there is no problem in blowing up the six-story experimental building where we are now. ”
