Versatile Mage: I can control you until you die

"Brother, tell me what's going on. What good stuff will you get this time?"

Shi Zheng held Xu Fang's neck and asked in a low voice.

"I have an idea, but I'm not sure." Xu Taiping answered frankly.

After all, he is not a scientist, and his understanding of most technologies comes from physical chemistry in middle and high school.

Bombs and drones are just that, after learning the principles, they try to use materials and magic circles from this world to perform reverse reasoning.

It's like a scratch-off ticket. There is a certain probability of winning, but a very high probability of not winning.

"It doesn't matter if you're not sure, everyone is born sure!"

Shi Zheng was more afraid of him giving up than Xu Fang, so he quickly complained:

“Brother, you don’t know, since those undead people collectively changed their homes in Qinling Mountains, the ancient capital has been safe, but there is no money left!

No, those companies that originally relied on the undead to survive have moved in the direction of Qinling Mountains, and teachers in small towns can hardly pay their salaries!

I’m not putting pressure on you, brother. You’re smart and can give us a clear path. By the way, you’re also the vice-president of our Bell Tower Magic Association! "

Xu Fang was so noisy that his head was buzzing.

The vice president was an honorary title given to him by Han Ji after the catastrophe in the ancient capital. At that time, the military also gave him an honorary military title.

"I'll give it a try and arrange a laboratory for me." Xu Fang said.

"It has been arranged long ago!"

Shi Zheng couldn't wait to put Xu Fang in the car and go all the way back to the Bell Tower Magic Association.

Research department meeting.

laboratory.

Basically all the materials that can be seen on the market can be found here, and a protective circle is even thoughtfully prepared.

If Xu Fang wants to do another explosion experiment, it won't blow up the room to pieces like at the beginning.

"call···"

Xu Fang took a long breath and sorted out what he had analyzed from the Wright brothers.

The phonological analysis ability is really useful, especially when visiting the array assembly line. The seemingly hidden defense is like giving a fool's tutorial.

Soon, the content was sorted out.

Putting these things away, Xu Fang began to experiment with his new ideas.

"Submarines can't do that."

The French world is different from the scientific plane. There are too many dangerous marine creatures, as well as all kinds of weird ocean currents and supernatural phenomena.

A diving facility is extremely expensive. Wouldn't it be heartbreaking to fold it in?

"Radar or sonar would be fine, but this thing..."

Xu Fang is really not trying to get along with Shi Zheng, he is really not sure about this thing!

In his previous life, he followed a popular science blogger and made his own voice-operated reversing radar for tricycles, and also built an ultrasonic mosquito-killing device, but it was not successful.

——These things are based on existing equipment and are completely different from the current pure hand rubbing.

Xu Fang touched his hair.

Hair gentleman, please be patient and you will be fine soon.

······

Xu Fang's retreat lasted for a week.

Bell Tower Magic Association, President's Office.

"Aren't you out yet?" Han Ji was a little worried: "Have you sent someone in to take a look? Don't cause any more problems."

"That won't happen. We eat all the food we bring in every day." Shi Zheng said.

Han Ji nodded: "It doesn't matter whether you can make something or not, but don't let it get to you..."

Bang!

The door was pushed open violently.

A figure rushed in and walked straight to Han Ji's desk. Who could it be if it wasn't Xu Fang?

Xu Fang hadn't had a haircut for a while, so he took off the hair tie that Jiang Shaoxu had put on his wrist and tied it into a casual short ponytail.

"you···"

"I'll say it first."

Xu Fang interrupted Han Ji, took out a large, strange-looking machine from the hidden star, and placed it on the table with a bang.

"What is this?" Han Ji didn't dare to move and looked at him with her eyes.

"Put in the magic stone and input the magic energy to try." Xu Fang said.

"Oh." Han Ji then discovered that there was a magic circle engraved on the machine, and he carefully input the magic energy into it.

drop!

The machine made a sharp sound, and then... disappeared.

Han Ji: "???"

"How is it?" Xu Fang asked.

Han Ji thought about the words and said uncertainly: "That's right... but I didn't understand it."

"Call Lao Yi." Shi Zheng picked up the phone and asked, and soon an old research staff member came over.

"The function of this magic circle is to mince the extracted energy." Xu Fang pointed to one of the magic circles and said.

The researcher translated in a low voice: "It is a magic circle commonly used on shield magic equipment. It decomposes the energy of the magic stone and spreads it to the entire shield."

Han Ji and Shi Zheng nodded in unison.

"This series of arrays can use the energy generated by the previous array to vibrate the air, thereby producing 'invisible sound waves'." Xu Fang added.

"this···"

The research officer was confused and couldn't understand Smecta.

Xu Fang explained:

"I am a sound mage. According to my understanding, sounds are produced through vibration. The stronger the mental power, the more violently the air is vibrated, and the stronger the magic is.

The vibration of water is stronger than that of air, and the solid body is even stronger, so sound magic has more advantages in water battles, and ordinary protective magic equipment cannot resist sound magic.

When fighting a space mage, if the opponent takes away the air, the sound magic will be greatly reduced. "

The research officer was still confused.

But a glimmer of understanding flashed in the eyes of Han Ji and Shi Zheng. They have been cultivating demons for many years, and their knowledge and understanding of elements are far beyond ordinary people.

"This spar,"

Xu Fang took off two crystal stones from the machine:

"This crystal is called the 'Thunder Stone' and is often used in the production of thunder-type magic weapons. The other is called the 'Moon Stone'. It has good conductivity and is often used as the energy transmission port of magic-slaying tools."

Xu Fang's purpose is to create ultrasonic waves.

The principle of ultrasonic waves is the piezoelectric effect, which also requires piezoelectric materials, vibration systems and drive circuits.

In the previous life, even if I killed him, I wouldn't be able to find such a thing.

——But again, in the magical world, talk less about non-magical science!

It doesn’t matter what your characteristics are, if I can’t find materials or replace you, I lose!

"Can this kind of sound wave be used for attack?" Shi Zheng asked.

"It's difficult." Xu Fang shook his head.

"That?"

"It can be used for positioning. Sound will be reflected back when it touches an object." Xu Fang said with a smile: "This principle is applied in the basic magic of the music system, 'Yin Xian·Tan'."

Shi Zheng looked at Han Ji subconsciously.

Han Ji is the president after all and has a better brain. He concluded: "You mean, you used this device to simulate elementary phonetic magic?"

"correct."

Xu Fang nodded in agreement: "No invention comes out of nowhere. Bombs come from fire and explosions, bees come from wind magic, and this thing in front of you is the product of music magic!"

"this···"

Han Ji, Shi Zheng and the research engineer's eyes changed again and again when they looked at the machine.

Xu Fang: "Of course, there are still many shortcomings, such as whether there are better materials, whether the signal reception can be connected to the computer... I can't do anything about these, and more research staff's wisdom is needed."

"enough!"

Han Ji suppressed the excitement in her heart, patted Xu Fang's shoulder hard, and finally said after a long time: "You have never let anyone down."

"By the way, this thing needs to have a name. It's up to you to do it."

name?

Xu Fang smiled and said: "Let's call it dolphin."

Calling a bat is too unlucky, as dolphins also emit ultrasonic waves, and dolphin sounds are the highest praise for humans in the field of vocal music!
