In the end, Luo Xiaotian survived well.

Later, he learned that even if the soldiers on the city wall accidentally let go, he would not fall, and the winch wheel set on the city wall would firmly jam the rope when it accidentally fell, and as long as he grasped the guardrail, there would be no danger.

In other words, if you don't grasp it steadily, you will fall?

Well, it's great that there are no accidents, this is Brown's job, but he has been on leave for the past two days, so Professor Scripps can only give this job to himself, so Brown won't deliberately take a leave of absence because he knows that this kind of work is going to happen, right?

The next time you meet him, be sure to ask.

After returning to school, Luo Xiaotian was finally able to continue his experiment of charging his mobile phone.

However, Luo Xiaotian has not yet figured out the principle of the magic array, this kind of magic array that releases miniature lightning is not like a battery, and he can't find where the positive and negative poles are, so Luo Xiaotian has no choice but to use a silver bar to draw out all the currents.

This can be regarded as the first time that Luo Xiaotian has used his own independent laboratory.

The laboratory was very small, and there was nothing in it, Luo Xiaotian set up the magic array and the silver bar as a wire and plugged it into the charging port of the mobile phone, and then stepped back a considerable distance, and set up two layers of mirror wall techniques in front of him.

Use the mage's hand to carefully place a small magic crystal in the center of the magic array, according to calculations, this magic crystal can support the magic array to continuously release miniature lightning for fifteen seconds, I hope the phone will not explode in these fifteen seconds, but... In case of any accidents, Luo Xiaotian can also verify the correctness of his other guess.

Start the experiment.

The mage's hand dissipated, and the magic crystal accurately fell in the center of the entire magic array, and the magic array began to operate.

Through the mirror wall technique, Luo Xiaotian saw that the screen of the mobile phone flashed, and then began to light up continuously, and the "sizzling" sound of the electric current could be clearly heard from afar.

Then, the red battery logo appeared, and in this way, it looked like it was half the battle!

"Boom!"

The phone exploded again, and black smoke filled out, mixed with debris flying everywhere, hitting the wall with a "crackling" sound, and even Luo Xiaotian's mirror wall technique appeared in a circle of ripples.

It's a failure, but it's okay to hold on for another five seconds. Then, it's time to test another conjecture.

When the black smoke cleared, Luo Xiaotian walked to the place where the mobile phone was originally connected, the silver bar made of silver coins had been bent by a violent explosion, and there was still a mobile phone in the place where the mobile phone was originally placed.

Sure enough, the phone seemed to have gained some kind of magical familiarity as it traveled through time, and no matter how many times it exploded, it would reappear in its original place.

Yes... Suddenly there was a feeling that the golden finger after crossing was wasted, think about it, if Luo Xiaotian obtained this strange attribute by himself, wouldn't he be invincible? No matter who the enemy is, how powerful it is, first of all, they will never be able to kill themselves, as long as they blow themselves up, they can be resurrected, and they will not die and get eternal life.

This is the highest state of the art that explodes, right?

Picking up the mobile phone on the ground, Luo Xiaotian pressed the power button with the idea of what to do, but unfortunately the phone did not react, and I don't know if it was because there was too little electricity charged in the previous moment, or every explosion would consume the remaining power in the mobile phone.

Then, there are two options next, the first is to find a way to effectively use the magic array to generate electricity, and the second is to find a new magic array.

After all, according to the previous situation, although it is only a little bit, but the phone is indeed charged with electricity, then this method is feasible.

Luo Xiaotian plans to continue to carry out the original plan, and use the magic array in the "Primary Magic Array" to re-study, at least to find a way to separate the positive and negative poles in the magic array, and this possible method may involve something that users only need to keep in mind and only researchers will study.

In short, it seems that trying to find a way to charge your phone is not a common hassle.

......

This is the third consecutive day that Luo Xiaotian has been reading books in the library this week, here, Luo Xiaotian needs to find inspiration from the vast books like the sea, and at the same time, Chrissy is by his side, and he can also ask his "senior sister" about these questions.

As for asking Professor Scripps directly, I'm sorry, Professor Scripps has been so busy these two days that he can't even find Chrissy.

"Ronald, the last time you asked me about the lightning magic circle, and now you are too, why are you suddenly interested in this magic circle?"

"Ahh I'm just interested in the magic array of the electric system, wondering if the flickering current can be used for any other purpose. ”

Wait, why do you have to be entangled in the current generated by the magic array? Luo Xiaotian suddenly found that he seemed to have fallen into some kind of misunderstanding, he still knew the principle of electromagnetic induction, so why didn't he just make a generator out? Even the magic motor he bought in Fink City before was left, and he didn't even need to manually generate electricity by himself.

Just do it, Luo Xiaotian threw the book in his hand aside and stood up.

"Ronald, where are you going?"

"It's okay, Chriss, you continue to read, I suddenly thought of something I must do, so I left first!"

Coils and magnets are not a problem, and now it is necessary to figure out how to generate direct current, otherwise it may be necessary to make something like a rectifier.

Luo Xiaotian didn't know this very well, but the first thing he had to do was to make a prototype that could generate an electric current, and only then could he really see the current before he could do the next thing.

Luo Xiaotian grabbed a handful of silver coins from his pocket and threw them on the table in his laboratory, melting them down into wires with very little resistance.

The next magnet needs to be bought somewhere else, if Luo Xiaotian is not mistaken, this kind of thing is available in the magic prop shop, of course there is a magic prop shop in Phoenix, and it is next to the Imperial Academy of Magic.

Luo Xiaotian suddenly felt that the feeling of eagerness in his heart was getting stronger and stronger, as if he longed to see that he had succeeded in creating a generator in the next moment.

Just as the emergence of electricity marked the second technological revolution, Luo Xiaotian also wanted to see if the emergence of stable current would lead to what kind of grandeur it would cause in the magic world.

Coming out of the school, Luo Xiaotian walked straight in the direction of the magic prop shop, because it was built next to the Imperial Academy of Magic, so business here has always been very good.

"Ronald?ha, we're meeting again!"

Gray robes, a slightly chubby body, ah... What's your name?... Forget it, in short, again, Luo Xiaotian saw Fink City, as well as the owner of Solomon's magic prop shop.
