The bright light, which exceeds the acceptable limit of the human eye, instantly illuminates the room.

"Ah, meineaugen! (German: Damn it!) ）”

Bismarck covered his eyes and screamed. Chu Feiyue smiled a little embarrassedly, found an iron box and put the sunlight glass ball in it. After waiting for about a minute with his eyes closed, Bismarck's eyes could barely see anything. While touching the tears that kept flowing from the corners of his eyes, he gritted his teeth and looked at Chu Feiyue.

"Chu, if you don't give me an explanation, I won't let you go!"

"Quite simply, I think we can use light as a conductor of oscillating cycles. The sheer speed of light can ensure that it can send the waves into the enemy's machine at the moment of impact, and nothing can be faster than light, can it? Chu Feiyue shook the iron box with the opening above, which could almost be used as a flashlight.

"My Cocoa Bean Star Man Box! Oh my God, it's a classic collector's edition, and it hasn't been produced since 1968! ”

However, Bismarck's direction of attention didn't seem to be quite the same as Chu Feiyue's, he was more concerned about the box in Chu Feiyue's hand.

"Huh?" Chu Feiyue lowered her head and looked at the iron box in her hand.

With a round body, a simple smile, short, spring-like limbs, and a superhuman costume with an "S" logo on his chest, maybe this is a European anime character?

Chu Feiyue was speechless, handed the box to Bismarck, he carefully placed it on the table as if he was holding the most fragile treasure, looking at it as if he was looking at his favorite lover, which made Chu Feiyue shudder.

"Alright, Bismarck, I don't want to hear you tell you about the relationship between you and this Cocoa Bean, get back to business." Chu Feiyue held her forehead and said helplessly.

Bismarck then took his eyes off the silly-looking iron box and looked at Chu Feiyue: "Oh, I'm sorry, what did you just say?" ”

Sure enough, you didn't listen to me at all, didn't you just listen to what I said? (╯‵□′)╯︵┻━┻

"I mean...," Chu Feiyue sighed and said, "I think we can use light as a conductor of oscillating cycles. The absolute absolute speed of light can ensure that it will enter the enemy's machine at the moment of impact. Is there anything you'd like to add to this idea? ”

"Running out? Is it OK to run out? I don't have much research on this. Bismarck frowned, and spoke generously about his soft feet.

"It doesn't matter, I can make a device that converts light into kinetic energy, even if the power is not very high, but as long as it all condenses to a single point, it can definitely penetrate any armor. What worries me the most now is how to spread out the oscillating cycles, because if all the waves can only propagate along the optical path, they will not be able to diffuse. ”

"Since you can handle it, it's best, let's make the test first. For the rest of the problems, look at the real thing to make adjustments, maybe it will be a little easier. Although he didn't know what Chu Feiyue was going to do, Bismarck still agreed.

As soon as he said it, Chu Feiyue began to make a small photodynamic converter, and Bismarck was on the side. Chu Feiyue is a skilled worker, so the work progress is quite fast, and in less than two hours, a small photodynamic machine was completed. Of course, this has a lot to do with the fact that Bismarck has a lot of materials and tools here. He actually converted half of the toilet into a parts warehouse, I really don't know how he got so many various types of parts into China...

Anyway, how did he squeeze into a pile of steel parts to go to the toilet?

Finally, the solar glass ball that is the power source is poured into the card slot, and the originally dim indicator light becomes green.

"Well, okay, then try the effect..."Chu Feiyue turned on the switch of this strange-shaped machine, forming a bright beam. Chu Feiyue aimed this beam of light at a steel plate that was placed on the windowsill, which Bismarck originally intended to use as armor, and then instantly adjusted the condensation of the beam to a higher level.

"Poof—"

With a soft sound, the pure white laser, which was so thin that it was almost invisible, pierced through the twelve-millimeter-thick steel plate. The steel plate shook twice and fell. Chu Feiyue turned off the machine, took the steel plate, and handed it to Bismarck.

On the steel plate, from the first hole all the way up, a straight gap has been cut!

“oh**！ Chu: Is this really what you did? I'm a special steel, and it's cut off like this? Bismarck's fingers ran a finger along the crack in the steel plate, which was still a little warm.

"It's assembled right in front of your eyes, and there can be fakes." Chu Feiyue shrugged her shoulders, "Now, I have proven that the piercing power of light is absolutely qualified, so next, we need to think about how to make the oscillating frequency free from the limitation of the light path..."

"No, no, no, no... Wait a minute, Chu, haven't you thought about it? Why do we use a frequency oscillator? Bismarck suddenly waved his hand and said.

"Why?" Chu Feiyue was stunned for a moment, "Of course, it's used as a weapon, short-circuiting other people's machines and making them stop running." ”

Bismarck nodded and pointed to the machine on Chu Feiyue's hand.

"Since it's a weapon, what is it that has the power of the one you hold in your hand right now? All it takes is a flash of light, 'puff-puff-', everything is broken, what are we going to do with all that fluctuating energy? ”

"But light can only go in a straight line... Bill, I seem to understand what you're saying, you mean, make an optical path cutter? Chu Feiyue lowered her head, thinking about the possibility of this line of thought.

Probably, should, almost, yes.

"Let's try again."

Chu Feiyue looked down at the photodynamic machine in her hand, picked it up, and turned it on again. Bismarck took out another steel plate and placed it on the windowsill, but this time, Bismarck also found two books as thick as a Chinese dictionary and fixed the steel plates one after the other.

The light swiped quickly, and it was put away by Chu Feiyue again. The killing of this machine is too great, and it is very likely to kill people if you are not careful.

The steel plate did not look like it had changed, but when Bismarck wanted to remove it, he only took half of it off...

Bismarck picked up the top part of the plate, while the bottom half remained between the two dictionaries, the incisions between them so smooth that they could even reflect light.

"Oh, Chu, are you sure you're not making a laser?" Bismarck shook the steel plate in his hand and asked with a funny expression.

"Of course not, the laser relies on heat to cut, it melts the object. With the help of the speed of light, I generated a huge kinetic energy to directly cut the object, and the most fundamental starting point is different. The main difference is that my light doesn't produce high temperatures, so you let the laser try? ”

As soon as this issue was mentioned, Chu Feiyue, like other scientists, praised his invention vigorously.

"Okay, you won, really." Bismarck raised his hand and begged for mercy, "Now, now that we have proven that this light can be used as a weapon, should we think about how to maximize the power of this weapon?" ”

Indeed, this kind of photodynamic machinery belongs to the directional type, and there must be a stable line to exert its power. But they didn't know what shape the other party's machine would be, so they needed to design a mobile template with multiple options and accept control, and finally they needed to make a platform that could move on the template to carry the superweapon.

These are all things that can be completed by consuming a lot of brain cells and blank manuscript paper, and they cannot be completed by a flash of inspiration.

They were busy together until the sun went down, and it was time for dinner before Chu Feiyue left. Originally, Bismarck wanted to celebrate the new breakthrough of the machine with Chu Feiyue again, but thinking of his roommate's strange taste buds and special hobby of destroying people's three views, Chu Feiyue was insensitive to this, and fled after saying hello. Bismarck scratched at the stubble he hadn't shaved for days, and went to eat his favorite old vinegar with some regret.

When Chu Feiyue left, he took the sunlight glass bead with his hand, and after several times, the sunlight stored in this bead had been almost used, and it looked a little dim, and it was still a little hot in his hand, which was a sign that the energy solidification was about to collapse.

Fortunately, such a super light source can only be made by Chu Feiyue, otherwise it would really be a mess in the world. Although because of the particles of light, the beam will disperse after a certain distance, and it no longer has such a strong kinetic energy, but that is also a matter of tens of meters later. Within this range, there are sunlight glass balls as an energy source, and Chu Feiyue's photodynamic machinery is the super weapon of the gods to block and kill the gods and Buddhas.

And most importantly, it's really simple to make zuò!

Before Chu Feiyue could go home, his phone rang. Today, in the twenties of the twentieth century, the legendary "On the Moon" of the Phoenix has long become an old song among old songs, and it is too maverick to be used as a ringtone.

In the surprised eyes of the surrounding crowd in one way or another, Chu Feiyue's old face turned red, and she took out the phone and looked at the caller ID, it was her sister.

"Hello? Qin Yue. ”

"Well, I'm not coming back today, well, I know, don't make trouble for others."

"I know, I won't poison myself myself, don't worry."

"Well, that's it, noon tomorrow? Take me with you? ”

"Okay, it's absolutely on time."

"Yes, haha, I'll see you tomorrow."

Hanging up the phone, Chu Feiyue sighed silently. Although it's a good thing that my sister has her own circle of friends, and I should be happy for her, but living together has become a common thing in life, and the sudden change is really not used to it.

Where are you for my dinner today...
