If Liangchen hears Lao Jun's heart, he will definitely kneel and cry, although those things are powerful, but the restrictions are too great, and they are disposable!

That's it, the truck is so big, you can't carry it on your body, and where can ordinary people have that kind of expensive guy?

Of course, he is just fooling Lao Jun now, and he doesn't care about the rest, anyway, Lao Jun doesn't know how to use it, maybe in his opinion, it's similar to the magic weapon he uses, light and portable.

"Liangchen, what you said about physics, I must learn! I must learn!" Taishang Laojun took Liangchen's arm.

"Lao Jun, listen to me, learning is not a problem, the problem is ......" The problem is that I don't understand it, but since Lao Jun asked, Liangchen can only catch the ducks on the shelves.

After thinking about it, he decided to start with the simplest physics knowledge - mechanics!

"Otherwise, you see I don't have anything now, next time I'll bring a book, and then slowly teach you how?"

There are no books, and Liangchen doesn't know how to talk about it.

"Isn't this there?" Lao Jun shook his beard unhappily, and a remote-controlled plane was placed in front of Liangchen.

Forehead...... You...... Laojun, although it is true that you are a god, but you can't jump so much at once, right? You don't want to think about it, this remote-controlled plane involves too much knowledge, okay? You don't understand the basics.

Seeing Lao Jun holding his mouth, Liangchen casually told him about it.

So he took the remote-piloted plane and first removed the battery.

"This is called a lithium battery, and it stores electricity in it, well, it's similar to the Qianyuan mirror of Our Lady of Jinguang, but the stored power is much less. You see here, when you need electricity, you take it here......"

After a long time, Liangchen started with lithium batteries, talked about the air flow of the wings of the aircraft, and explained why the plane was able to fly.

Then he explained electromagnetic waves, which the remote control emitted to the internal circuit board of the remote control aircraft received. Call high and low level, analog-to-digital conversion, digital-to-analog conversion.

Then he talked about the working principle of the circuit board, and told him all kinds of originals, of course. Basically, Liangchen knew each other in high school, and some skipped if he didn't understand.

As for how it works, Liangchen is half-understood, half-witted. But explaining to Lao Jun, a person who doesn't know anything, he is blowing a lot.

It's just those so-called high and low levels. But it was understood by Lao Jun as "yin and yang", and Liangchen did not refute him, but followed his meaning, using yin and yang to represent high and low levels, which cast a thick layer of mystery on the circuit.

In the end, Liangchen finally finished speaking, and I don't know how much Lao Jun knows, anyway, he talks about his own, and Lao Jun nods vigorously.

"Okay, that's about it. As for the question of circuits, it is too broad. And electromagnetic waves, well, I'll go back and ask Master to discuss it with you in depth. ”

Liangchen had never found it so tiring to talk about knowledge, and at this moment he finally knew what it was like for the teacher to give a lecture back then.

Taishang Laojun also breathed a sigh of relief, "Oh, listening to your words is better than reading for ten years! I didn't expect this electricity to be so useful!

Esoteric? Esoteric, that's right! I've been studying things for years, and I'll finish it in an hour for you!

"Well, after all, when it comes to the laws of the Heavenly Dao, it is normal to be profound. I don't know how much Lao Jun understands?"

Liangchen still pretended to be mysterious. Then probe the foundation of Lao Jun a little bit to prepare for the next explanation to him. Otherwise, the next time he catches the duck on the shelf, he really won't have any ink!

Lao Jun was ashamed and said, "The old man is stupid, he just understands various components and the principles of aircraft flight. There is also an electromagnetic wave, which is somewhat similar to my air control items, that is, the circuit, the old man really can't figure it out. ”

Burst......

Liangchen almost spurted out a mouthful of blood, Mom, what kind of freak is this? You understand so much in an hour? You don't seem to understand basic mechanics, do you?

And even electromagnetic waves are understood!

Fortunately, you didn't understand the circuit, otherwise, I would have mastered the theory of electricity in an hour, I really wanted to cry, if it wasn't for the fact that Liangchen was interested in middle school, and he also took two courses on physics in college, so he understood it, otherwise he wouldn't have understood it at all.

However, for Taishang Laojun's electromagnetic waves and air control items are somewhat similar, Liangchen is a little very interested!

He can't fly, and it's not a matter of a day or a half to learn now, he's not an old gentleman, and his comprehension is not so high.

But it would be nice if he could learn how to control items in the air! Although he can usually put things into the Qiankun bag with a big wave of his hand, or take out the contents of the Qiankun bag.

However, that is based on the Qiankun bag and can only be passed between the Qiankun bags. If you usually drink a cup of tea or something, you can't just move your mind, and the teacup will be in your hand.

He's not that good yet. Unless you use the Qiankun bag, put the teacup into the Qiankun bag at close range, and then take it out of the Qiankun bag. It's a bit unrealistic.

Liangchen cleared his throat, straightened out his emotions, and then praised, "Laojun, I didn't expect your comprehension ability to be so high, I studied with Master at the time, but it took me three years to learn all the knowledge thoroughly." By the way, what do you mean by electromagnetic waves and control items?"

Hearing this, Lao Jun was very proud, which means that he has a strong ability to penetrate the laws of the Heavenly Dao?

For the connection between electromagnetic waves and mind control that Liangchen said, he didn't think it was a secret at all, anyway, it was not difficult for mind control items, as long as the gods with a little talent understood it.

It's just that if you want to associate electromagnetic waves with mind control, Lao Jun has comprehended it with his comprehension ability. It just so happened that he discussed this as a learning experience and Liangchen.

"It's actually quite simple. You're not saying that electromagnetic waves are actually a kind of particle vibration, and electromagnetic waves of a specific frequency can be picked up by a specific receiver, which is actually the same as mind control.

For example, if you want to control the fruit, you have to stare at it, then see its vibrations clearly, and channel a vibrating wave through a spell that is connected to the fruit.

Then pull the wave back, and the fruit will follow to your hand. Of course, if you're not familiar with it, you'll need to hold it up with a ball of air underneath the fruit.

If you are familiar with it, you don't need it, the fruit will vibrate and soon come to your hand! And the familiar person doesn't need to stare at it, just send out a few vibrations at random to be able to pull it over. ”

Saying that, Lao Jun smiled, and without looking at it, he searched for an apple and pulled it in front of him.

"Actually, it's just a very simple spell, it depends on your observation of the vibration of this apple, and the control of the vibration of the airflow!" (To be continued.) )
