Chapter 45 Dorabooma and the Black Somersault Cloud
In the laboratory.

Bulma first took out a pair of strange-style goggles and gloves, put them on Uchiha Hikaru, and also put on a pair himself, and then took out a device that looked like a flashlight. After pressing the switch, a narrow and blade-like light purple beam was immediately released, extending to two or three meters before spreading slightly.

"This is a laser sword. The components of the beam include ultraviolet, infrared... and gamma rays and X-rays. As long as you press a button, they can be released in the form of high-energy beams, and then constrained by magnetic fields to form the shape of the sword. You can adjust the intensity of the light here when using it..."

"However, this kind of beam will cause some damage to human skin. You need to wear goggles and gloves, and be careful not to hit others... If Xiaoguang is you, there will definitely be no problem in using it."

"Um……"

Uchiha Hikaru watched Bulma displaying several lightsabers one by one, and pondered for a moment: "Have you paid the copyright fee to the Jedi Order?"

"what?"

Under Bulma's puzzled gaze, Uchiha Hikaru didn't explain too much. He walked over and took a lightsaber and tried to wave it a few times: "These beams...are not tangible?"

"Of course, it's just light, how could it have an entity..." Bulma's tone was matter-of-fact.

Also.

Whether it is lasers or rays, they are essentially just electromagnetic waves. They will pass through directly when they come into contact with each other. They cannot crackle for a long time like fluorescent tubes.

"But what you said, Xiaoguang, is theoretically possible."

Boomer rubbed his chin and thought: "If the laser is replaced by ultra-high-density plasma, and a strong constrained magnetic field is used to control their shape, it can indeed cut objects like a real sword... But the plasma particles After colliding with neutral air, energy will be lost immediately. This problem must be solved to allow the lightsaber to maintain for a long time..."

While Uchiha Hikaru looked confused, Bulma had already given up this idea and walked to the next workbench:

"and this."

"This is an ultraviolet protective clothing. It is heavier than an ordinary coat. When you wear it, just press the switch, and it will instantly form a strong sun-like light, forming a 360-degree all-round illumination around the body without blind spots. It's as bright as day. If there are no trees or buildings to block it, it can cover a radius of two hundred meters, and the energy can last for about two to three hours..."

"...Sun Fist, right?"

Uchiha Hikari couldn't help but complain.

And Boomer continues:
"But last time I heard what you and Tanjiro said, I wasn't sure if this thing would be useful, so just to be on the safe side, I invented a new thing. Qiang Qiang~ This is it!"

"I named it 'Mini Bracelet'. As long as you wear it on your wrist and press this button, your whole body can shrink to the size of your index finger, and then you can hide it in your pocket."

With that said, Bulma demonstrated live. As the button was pressed, her body shrank to only a few centimeters at a speed visible to the naked eye. She stood at the feet of Uchiha Hikari and waved.

"...6"

Uchiha Hikaru admitted that he did not understand science.

But in her mind, shrinking a person instantly to the size of an index finger is much more incredible than a laser sword or plasma. But listening to Bulma's tone, the invention process of this thing seems to be more complicated than the previous two. It went much smoother... Considering that there is a magical thing like a universal capsule in the Dragon Ball world, the principle of changing size anywhere may not be complicated at all.

only……

(This technology tree is not an ordinary crooked one...)
Moreover, even counting from the last time she found the Dragon Ball, the time left for Bulma to invent was only more than two months at most, during which she had to go to school... The efficiency of this invention was really a bit ridiculous.

"Are there any other new inventions, Dorabooma?"

Uchiha Hikaru blinked and looked at Bulma expectantly.

Under her gaze, Bulma scratched his head in embarrassment: "No more... Actually there is another plan that is being improved, which is a firearm version of the laser sword, tentatively named 'High Energy Particle Gun', but that one has just been made. There are many technical issues that have not been resolved before the samples are released, so I won’t show them to you, Xiaoguang, this time.”

"..."

There really are...

Uchiha Hikaru was a little speechless. She had previously thought that no matter how talented the 16-year-old girl Boomer was, her level would be limited. In the original plot, things like her inventing a spaceship and a time machine were almost ten years later. But now it seems...she underestimated the value of the word "genius".

"Limited level" is only compared to the older generation of top scientists such as Dr. Breeve and Dr. Gro, but compared with ordinary scientific researchers, Bulma no longer knows how high he is.

(It seems that I can take the time to talk to Bulma about the idea of ​​the "gravity training room" and come up with this training method in advance...)
Uchiha Hikaru chatted with Bulma for a while, and after verbally finalizing the departure date for Demon Slayer World, he stood up and left.

Then he flew all the way to the holy land of Karin and climbed to the tower to visit the Cat Immortal.

I can tell.

The Neko Sento was a little happy about Uchiha Hikari's arrival.

After all, Kalin Tower is isolated from the world, and the gods above rarely come down. Only this lonely old cat stays here every day. There is no one to talk to. He can only pass the time by observing the lower world. After a long time, it is still quite good. lonely. Uchiha Hikaru had already anticipated this, so the Neko Immortal brought a large number of gifts——

A pile of comic books, novels, CDs, and two video players.

"What is this, an invention of the human world?"

"Well, it's something to help you pass the time."

It's a pity that the entertainment industry in the Dragon Ball and Naruto worlds is not very developed. If the entertainment products from the 21st century earth can be brought here, Neko Sennin will not have to worry about running out of things to play in the next few decades.

After briefly teaching the Neko-Senji how to use the video player and demonstrating it himself, Uchiha Hikaru asked the Neko-Senji for advice on the problems he had encountered recently when practicing "Qi".

That night, Uchiha Hikaru used the kitchen utensils left last time to cook and stayed on the tower.

I stayed like this for three or four days.

She was just about to leave to go back.

This time, Uchiha Hikaru didn't ask for any more fairy beans.

After all, she had brought a big bag with her when she went back last time. Although there were a lot of fairy beans at this time, including several jars, and the Cat Fairy himself didn't care much about fairy beans, she couldn't ask for them too often. , but annoying.

As long as you come to visit from time to time and make a good emotional investment, you can just pick up a few jars in the future and realize the freedom of fairy beans.

——It is better to be taken away by her than to be devoured by Yajirobei in the future.

And the god in the temple would probably have to be introduced by the Cat Immortal before he could have a chance to meet him...

but.

Although Uchiha Hikaru didn't speak, Neko Sento suddenly called her before she left.

"What's wrong, Master?"

"...I did not promise to be your master."

The Cat Sage first denied Uchiha Hikaru's title, and then said: "Didn't you say last time that you wanted me to give you a somersault cloud? In fact, in addition to the golden somersault cloud, there is also a black one, this kind of somersault cloud. You don't have to be pure of heart to be a cloud, even people with evil hearts can sit on it. If you don't mind it, you can take one back with you."

As if to prove his words, the Cat Immortal raised his crutch and waved it, and soon a purple-black cloud flew from the sky and landed in the Kalin Tower.

"Eh?"

Uchiha Hikari looked at the somersault cloud, vaguely thought of something, and asked a little unnaturally: "Master, you don't want to throw me down when I'm halfway flying, do you?"
