Berexi looked at Li Hengxin's back in a daze, with mixed feelings in her heart, was his slap for himself?

As the granddaughter of the Prime Minister of the Empire, Weinuo is undoubtedly the proud daughter of the sky, even in the Imperial Academy, which is full of nobles, there are only a few students who can compete with it. Pen, fun, and www.biquge.info

But today, in front of other students, Li Hengxin slapped her ears fiercely, not only Bei Leixi's heart was shocked, but even Weiwei Nuo felt dazed, looking at Li Hengxin's back, her heart continued to fluctuate, you can know how angry she is in her heart now, and finally she turned around angrily and ran away with red eyes.

Li Hengxin, who was not happy, wanted to find Omar, first the teaching office, and then his magic tower, but he didn't see a figure, and he was depressed and just wanted to go home, but Omar came head-on.

"Where have you been? I've been looking for you for a long time and I haven't found you. Li Hengxin's tone was a little unkind.

"I ...... I'm going to the dispatch office to pick up this month's supplies, Li, you don't look good, nothing happened, right?" Omar asked with concern, as his first friend, Omar didn't mind Li Hengxin's tone, but cared about him first.

"I'm sorry...... I'm fine. Li Hengxin let out a long sigh, knowing that he shouldn't vent his temper on his friend: "Go, see what you have received...... I searched for you for a long time and couldn't find ......"

The two of them returned to the magic tower, and Omar took out the materials he received from his space bag, there were hundreds of magic crystals, as well as a little bit of precious magic metals and some ordinary metals, or magic materials, such as cursed flowers, starlight plants and other magic plants, in short, varied, strange.

"Omar, do you have a way to make that kind of magic communicator? It's a magic prop that can be used by two people to talk to each other at a long distance?" Li Hengxin asked on a whim, as an earthling who is used to using mobile phones, if there is no such thing, he always feels that something is missing, and it is so difficult to find someone.

"Of course you can, but the magic communicator requires a high-level magician to use, and the farther away it is, the higher the mental power consumed, and the maximum range can't go beyond the imperial capital at all, and every word you say has to be sent out with spiritual power, it's simply a crime. Omar said helplessly.

"So troublesome?" Li Hengxin's brows furrowed.

"So basically no one can use a magic communicator now, it's just mental torture, and when what needs to be said is finished, the mental power is almost consumed. "Omar is clearly familiar with the magic communicator.

There is obviously no so-called signal in the Omis continent, and all long-distance information is transmitted by spiritual power, which undoubtedly increases the consumption of spiritual power.

"Sophia, bring me the information about the 21st century walkie-talkie, the kind of direct signal exchange. Li Hengxin said to Sophia.

"Omar, follow this, help me make one. Li Hengxin took out a drawing, which was drawn by Sophia.

"What kind of drawing is this?" Omar looked at the dense circuit drawings, and a feeling of vomiting came to his heart, although alchemy is very magical, but it can't make such a complicated thing, Li Hengxin obviously believes in alchemy too much, Omar's face is a little embarrassed: "This ...... It's a little bit more difficult......"

"Forget it, I'll do it myself. Li Hengxin knew that this was too embarrassing for Omar, so he was ready to do it himself, the connection of the circuit board was a very delicate thing, Li Hengxin took out a full set of tools, and prepared to manually make a few walkie-talkies.

Omar also watched Li Hengxin's actions seriously, although Sophia could create a walkie-talkie immediately, but unfortunately it was incompatible, the things she created belonged to a unique type, even if she created two walkie-talkies, it would not be able to talk.

Even Li Hengxin can't complete this complicated process, but whenever he makes a mistake, Sophia will point out from the side and point out the crux of Li Hengxin.

Omar was a little dumbfounded, he didn't know about Sophia's existence, he thought that Li Hengxin could write down such a complex circuit diagram just by relying on his own head.

However, time also passed quickly, and Li Hengxin also entered the point of forgetting to sleep and eat, and even forgot to go home.

"Omar, help me make this copper so thin as a hair...... The exterior is then wrapped in snake skin...... Do more in quantity"

At this moment, Omar is completely willing to make a move, what Li Hengxin needs, Omar will provide him, although Omar doesn't know what Li Hengxin wants to do, but his strong desire for knowledge makes him a little unstoppable.

Both of them had forgotten the time, the night had already fallen, and they had not eaten for a whole day, but they had no appetite at all.

"Omar, refine a few according to this appearance. Li Hengxin pointed to the shell of the walkie-talkie on the drawing and said, "Use wooden materials, you don't need precious magic metals." "Li Hengxin will let him do more no matter what he wants Omar to do, because walkie-talkies are needed more to be useful, what is a walkie-talkie for!

"Husband, the materials here are simply not enough to make the batteries needed for walkie-talkies. Sophia said to Li Hengxin.

Li Hengxin took this half-finished walkie-talkie and sat down quietly, the battery seems to be the biggest problem! Without energy, this walkie-talkie is a waste.

No, this walkie-talkie should belong to the type of the public, and it shouldn't become the patent of a few people, right, the magic crystal!

With the energy content of the magic crystal, it can provide energy consumption for a long time, but the biggest problem is the conversion of energy, how to convert the energy in the crystal into electricity, or the electric element.

"Omar, do you have a way to convert the energy of the magic crystal into an electric element?" Li Hengxin asked as he turned his head.

"Of course, this is very easy, as long as I can transform the energy of the magic crystal into various elements through the transformation of the magic array. Omar can finally say it proudly.

"Then you can show me a show. Li Hengxin said.

Omar took the crystal and began to depict a palm-sized magic circle on the parchment drawing, and then pressed the crystal on the parchment, when one end of the magic crystal touched the center of the magic circle on the parchment, there was an immediate sizzling sound, and bursts of blue light flashed on the magic array.

Li Hengxin grinned, and the solution was in front of him: "Omar, it's time for you to do it......"

The magic array is carved on the inner shell of the walkie-talkie, and the magic array is adjusted through a button, and if you want to turn off the power, then press the button, the magic array will be in an incomplete state, and the power supply will disappear.

However, for walkie-talkies, the power consumption is very small, a low-level crystal can work for more than three months without interruption, after all, a battery on the earth can be used for two or three days for mobile phones, and the energy contained in such a low-level crystal is even more considerable.

Through the signal connection with Sophia, Li Hengxin has experienced that the walkie-talkie he and Omar made has been successful, and in addition to being excited, Li Hengxin and Omar together again continue to make walkie-talkies, but after the first one is completed, the next few are much simpler, and most of the materials have been completed.

The first walkie-talkie Li Hengxin and Omar took nearly a day to complete, while the latter ones only took half a night to complete.

"Ah...... It's done!" Li Hengxin finally stretched his waist: "Huh, it's dawn!"

"Li, we've been doing it all day, and you haven't told me what you're going to do? Now that it's done, it's time to say it, right?" Omar looked at Li Hengxin expectantly.

"Magic communicator!" Li Hengxin said with a smile: "Now you take a communicator and go downstairs, and then adjust this frequency here......" Li Hengxin explained the usage and efficacy of this walkie-talkie.

Omar walked down the stairs suspiciously, and began to cough tentatively into the walkie-talkie, obviously embarrassed.

"Omar, do you hear it?" Li Hengxin's clear voice came from the walkie-talkie, Omar's eyes lit up, he suddenly lost his sleepiness, and he had no doubts in his heart, and said excitedly: "I heard it, ......it was very clear" Omar, who had not heard the phone, was very excited, and perhaps other people would be shocked by the advent of the walkie-talkie, but Omar was more proud, because he participated in the manufacture and design of the walkie-talkie.

"Very well, now you walk out of the school gate, we start testing the effective distance, and every kilometer crossed, we have a conversation. Li Hengxin said.

Omar was very excited, holding the walkie-talkie in both hands, like a treasure, the two of them forgot to go to class at all, Li Hengxin also moved in the opposite direction, so he kept pulling the distance, and finally the test concluded that the effective distance of the walkie-talkie was about twenty kilometers.

If Omar admired Li Hengxin before, then Omar now worships! There is no need for any consumption of spiritual power, as long as a small amount of crystal energy is consumed, he can walk and talk to Li Hengxin at the same time, and he doesn't mind the white eyes of passers-by at all.
