I picked up the dragon girl at the beginning and I used artillery fire to liberate the other world

After a few days, Wald had completely understood the electromagnetic induction phenomenon that His Highness Bai Yan had given him, and the idea of ​​designing a thermal power generator based on this principle was also completely feasible.

He had never thought that lightning, a terrifying energy unique to nature, could be controlled by His Highness Bai Yan.

First there was fire, then thunder and lightning. Wald even imagined whether the land, wind, water flow, and everything in the future would eventually be controlled by His Highness Bai Yan.

Excited, besides being excited, I am also proud.

What a great discovery this is! It may even overturn everyone's lifestyle.

After an initial testing phase of about a week, a small thermal power generator was set up.

It is connected to a wire made of copper wire and extends to a thing called a battery.

"Get ready, you can start burning coal." Wald directed his students and started the first test.

As the flames in the boiler burned fiercely, the turbine was driven by the heat and started to run.

As the moving turbine passed through the magnetic field, the small light bulb with tungsten filament on the battery lit up.

"What is this? Success?" Wald showed an unbelievable look. Although the light emitted by the bulb was not as bright as a candle, in his eyes, it was brighter than the hottest sun.

"Teacher, is this electricity?" His students couldn't help but gather around him when they saw this. They all stared at the small light bulb, unable to come back to their senses for a long time.

"Your Highness Bai Yan is simply a god! This is a miracle!" Wald shouted excitedly and couldn't help but reach out to wipe the exposed copper wire.

In just a moment, the tingling sensation made him throw the copper wire away.

The generator used in Suo Xin's test was only a tiny model, and the voltage it produced was not set too high, otherwise Wald would have been burnt to a crisp.

"Verification successful, quickly inform the engineering department that they can start construction!!"

Ignoring his unconscious arm, Wald's face turned red, and he couldn't wait to let the world see this great invention.

At night, Walder came to the Lord's Castle of Baiyan with the fully charged small battery.

"Your Highness! This is electricity!!!"

Arriving at the back garden, Wald placed the battery in front of Bai Yan.

"How is it? Isn't it interesting?" Bai Yan laughed and patted Wald on the shoulder. "I have another book on electromagnetism here. I'll show it to you after I finish copying it."

"Really? Thank you, Your Highness!" Wald nodded excitedly, even ignoring the copying in Bai Yan's words.

Looking at Wald's crazy look, Bai Yan knew that if this guy went to college to study those physics courses, he would definitely beat 99.99 percent of college students.

As early as a few days ago, Bai Yan had already designed the light bulbs and asked the factory to process a lot of them for him.

Moreover, the entire lord's castle had already been carefully planned and designed by him, and the route was already clear.

Everything is waiting for the moment when the power station is built.

"Your Highness, shall we start now?" Wald had already aligned the interface of the line with the positive and negative poles, waiting for Bai Yan's order.

"Don't be impatient, wait for me." Bai Yan remembered something, walked into the castle, and pulled up Sophia, who had been waiting on Bai Yan's bed.

He also called out Alicia and Alyssa who were eating dried fruits in the kitchen.

Finally, Iris, who was practicing, and Constance, who was guiding Iris in her practice, were pulled out.

A group of people stood in the garden in a daze, not knowing what Bai Yan was going to do.

"Ahem, I'm sorry to interrupt you all, but in order to prevent you from accidentally breaking the light bulb, I thought about it and decided to pull you out."

"Bai Yan!! Didn't I just eat a few of your dried fruits? Why are you not letting me eat them and making me poop?

Don't forget! You still owe me three gold coins."

Alyssa's face immediately turned red with shame and anger. The big thief thought Bai Yan was going to publicly criticize her for being greedy.

"You only care about eating! Wait until I finish my work, and then you can eat however you want, okay?" Being interrupted by the gray-haired girl, Bai Yan glared at her unhappily.

"You said it, don't go back on your word." As if realizing that she had misunderstood, Alyssa couldn't help but lower her head, her tone as weak as it could be.

But his wandering eyes clearly hinted that this guy was secretly delighted because he could eat Bai Yan's food for free.

"Husband, what exactly do you want us to see?" Sophia, who thought Bai Yan was going to do something to her, was pulled out of bed by him. Naturally, she felt a little resentful.

But the word "husband" still made the air quiet for a few seconds, during which time Sophia's face turned red.

"Hehe~" As Constance sneered twice, Sophia buried her head directly in Bai Yan's arms.

"Okay, stop! I'm going to announce something serious now!" Bai Yan noticed Constance's gnashing expression, and felt a little guilty inside, so he could only pretend that he didn't see it.

"Yes, His Highness Bai Yan now has two beauties, so he has to announce it."

Seeing that Bai Yan didn't want to pay attention to her, Constance felt unhappy for some reason.

However, after saying this, Constance regretted it. What's the difference between her and being jealous?

Alicia's tail had stopped wagging. She had a dazed look on her face. She and Sophia looked at each other secretly, and finally they both turned their eyes back to Bai Yan.

"Well, what I announced today has nothing to do with all this. What I actually wanted to say is - this!!"

As Bai Yan snapped his fingers, Wald, who had been shivering at the back, quickly connected the wires to the positive and negative poles of the battery.

As Bai Yan's most loyal believer, Wald naturally understood Bai Yan's desire to show off at this time.

As the light bulb flashed twice, all the rooms in the lord's castle became brightly lit.

Even in this garden, there are a few small light bulbs, adding a bit of romance.

For a moment, except for Bai Yan and Wald who was already fleeing, everyone was stunned by the suddenly bright world.

This kind of brightness cannot be compared with those crystal lamps which can only emit faint light. Just like a sun and a star, the light emitted by the light bulb brings subversive changes to the world.

"What's going on? It's so bright!" Alesha spoke first, breaking the shocked atmosphere.

For a moment, everyone looked at Bai Yan with admiration.

How did this man do it? Even light magic couldn't keep the entire castle lit for such a long time, right?

What's more, this is clearly the brightness emitted by the small glass balls themselves.

This is really incredible.
