At the same time, Xia Fan was sitting in the small room of the Lingbu Department, giving his first lecture.

Since the last time she watched the test firing of the electromagnetic cannon, the princess has been interested in shocking. He thought that the other party was just talking, but he didn't expect Ning Wanjun to be very serious, every time he saw him, he would ask when the last sentence would start to be taught, so he simply called all his people together and opened a seismic class.

In addition to the princess and maids, there were also Li, Luo Youer and Wei Wushuang sitting in the audience.

These people are all Xia Fan's very trusted partners, and if they can all master the convenient shaking technique, it will also be a great improvement for their own power.

And his first sentence surprised everyone.

Except for Lai.

"The introduction I actually used wasn't lightning wood, it was something else. ”

"Isn't it lightning strike wood?" Wei Wushuang was the first to react, "What about its origin and rarity?"

"It's very cheap, and ordinary blacksmiths can provide it, and it's about half a tael of silver. Xia Fan displayed a copper wire pendant in front of everyone, "If there is a skilled craftsman, its cost can be reduced by about seven or eight percent." ”

"Again...... Lower seven or eighty percent, on the basis of half a tael of silver?" Luo You'er gasped. As a disciple of the family, she knew all too well what this meant.

Just selling the formula of the medicine is enough for Xia Fan to spend money for the rest of his life!

"He can't sell it. Ning Wanjun guessed everyone's thoughts, "This amount of money is too big, enough to cover it with his life—if he doesn't have the ability to protect himself." ”

Although her tone was pretending to be calm, the princess still set off a monstrous wave in her heart.

Is this the hearer as it is heard!

It's too much!

A salt-making technique, a seismic primer, these are all things with extremely broad prospects, and he can actually "hear" them? His mind does not seem to be affected much, and the unfairness of the heavens is undoubtedly reflected here.

Perhaps even among the listeners, he was lucky enough.

After all, judging from the vigilance of the Privy Council, there is definitely more than one listener, and if they are all like Xia Fan who can bring earth-shaking changes, the world should have been chaotic a long time ago.

After the monstrous waves, there is an indescribable satisfaction.

After all, such an amazing listener is now at her disposal.

And she personally selected it from the taxi exam!

No, Ning Wanjun coughed twice, he hasn't verified it yet, and it's not too late to be proud when he confirms, "You mean, this thing can completely replace the lightning strike wood?"

Xia Fan threw the copper wire pendant into the princess's hand, "I have tried many introductions, and there are no less than five that are stronger than the lightning strike wood, but the most obvious transformation effect is still this copper wire pendant." ”

There are no less than five!

This sentence caused a wave in everyone's hearts.

Wei Wushuang didn't know what to sigh about, "When I was in Qingshan Town, I knew that Brother Xia must be extraordinary, but I didn't expect it to come to this point. ”

After Ning Wanjun got the pendant, she took a closer look.

It was the size of a thumb and weighed about the size of a stone, wrapped in thin copper wires on the outside and a black stone on the inside.

Judging from the appearance alone, this thing has nothing to do with the seismic method.

With a puzzled thought, the princess walked to the room where there was no one, meditated on the spell casting process, and softly pronounced the name of the spell, "Earthquake Return, Streamer!"

The copper wire pendant remained motionless, and nothing changed in the room.

"Your Highness......" Qiu Yue raised his forehead, "Fangshu is not something that can be learned overnight. ”

"But I've tried it with lightning strikes. She wondered, "Even if it doesn't work, it has to change a little, right?"

"How much did you use?" Qiu Yue said in surprise, "Does Grandpa Li know?"

"It's only five or six, and he won't care if I use it to practice the arts. Ning Wanjun glanced at Xia Fan, "After visiting the Shikao, I specially prepared a box of lightning strike wood, which was originally intended to be given to you as a reward, but it seems that you don't need it anymore." ”

Qiu Yue's tone was full of distress, "That's all silver......"

"Ahem, thank you princess for your kindness. Xia Fan cleared his throat, "Have you succeeded in your practice?"

"The last time it should have been done," Ning Wanjun wondered, "but this thing doesn't seem to be able to be activated by my qi, and it makes me feel no connection with thunder and lightning." ”

"No connection?" Xia Fan couldn't help but be a little surprised, "Hmm...... It's better to try someone else first. ”

Luo Youer and Wei Wushuang took the copper wire pendant in turn, but the result was exactly the same as the princess.

The technique not only pays attention to the mind, but also highlights a problem of proficiency, but even if it fails, it is at most not effective, as long as the idea is okay, the copper wire pendant will still be consumed. However, it turned out that no matter how much they tried to use the shock technique, the introduction remained in their hands without moving.

In the end, only the fox demon remained.

"Sister Li, work hard!" Luo You'er couldn't help but cheer her up, as if the fox demon had become everyone's hope at this moment.

In the eyes of everyone, Li picked up the copper wire pendant.

She remembered that Master had said that magic was a process of reconstructing thoughts, and that the more details could be constructed, the more Qi could be used to reshape them. For a moment, she seemed to recall the rainy night of her childhood, when the wind and rain outside the bamboo forest were blowing, almost wetting her fur. Just as he crossed a puddle, the surface of the water reflecting the night sky was suddenly lit up by electric light—

"Earthquake Return, Thunder!"

Boom –

A thunderclap seemed to come from a long distance, short and faint, and disappeared without a trace in a moment.

"It's done?" Luo You'er looked happy, as if she had her own credit for this.

"No, the copper wire pendant is still in her hand. Wei Wushuang shook his head.

"The thunder just now ......"

"Probably a double technique. ”

Xia Fan looked at Li in surprise, he had long known that the disciples of Qingjian were extraordinary, but without the help of introductions and talismans, he could cross two hexagrams to perform spells that were very different from his heart, and he could also listen to it, this talent was indeed not comparable to ordinary monks.

It's just that this movement has nothing to do with the copper wire pendant.

"How can this be?" Li Bai was puzzled.

Xia Fan also had the same idea at the moment.

In other words, this improved seismic technique has no effect on them!

"Are you sure this thing can cause a seismic technique?" Ning Wanjun doubted.

"I've been curious about this for a long time. Wei Wushuang scratched his head, "Brother Xia, does your improved introduction have anything to do with the thunder and lightning in the sky? The things in the blacksmith shop are nothing more than copper and iron tools, right?"

"Of course it does," Xia Fan said as a matter of course, "It can be used to generate electricity, although the structure needs to be adjusted slightly, but it is better than lightning striking wood - reliable......" Speaking of the back, his voice was lowered, and in the face of everyone's blank eyes, Xia Fan suddenly thought of a key point!

The biggest difference between them and themselves is that they have never seen electromagnetic rotors generate electricity.

If you haven't seen it, you can't imagine it!

It's not enough to have an introduction.

This improvement, from the very beginning, worked only for him!
