Having said that, lightning strike wood itself does not produce lightning, but in people's consciousness, it is a proof that electric light remains in the world, so it has become the best material for seismologization.

This may seem illogical, but it does not defy common sense.

Xia Fan found a huge mystery in front of him.

How common sense must be to be considered "common sense"?

Fantasy obviously doesn't count, he's confirmed it on his wanderings, but common sense can be reversed.

When people realize that lightning strikes have nothing to do with lightning, will this material still be effective?

Then again, he never seemed to have ever tried the effect of lightning striking wood.

"Xia Fan?" Li's voice pulled his divergent thoughts back to reality.

Xia Fan pondered for a moment and looked at the audience solemnly, "I want to conduct an experiment, and I hope you can cooperate with me to complete it." ”

"No...... Does it hurt?" Luo You'er asked cautiously.

"Probably a little. ”

"Huh!"

"Just a little. Ning Wanjun was not afraid, "Then what can it verify, or what benefits can it bring?"

"I guess I can see you to the other side of the world. Xia Fan thought for a moment, "If you're lucky, maybe you can master the earthquake technique on the spot?"

Qiu Yue shuddered, "Your Highness—"

"Interesting, let's do it. The princess said without hesitation.

"By the way, Your Highness," Xia Fan stretched out his hand to her, "Do you still have more lightning strike wood there?"

......

An hour later, the crowd regrouped in the small room.

In addition to gathering all the materials needed for the test, Xia Fan also had an extra lightning strike wood in his hand.

This was the first time he had seen the materials that were originally intended for the Seismis.

This wooden root is about one finger long and two fingers thick, and presents a complex hollow structure in the middle, as if it has been carbonized by lightning in an instant, leaving only intertwined meridians. To prevent moth-eaten and rotten, its entire body has been brushed with tung oil, making it look crystal clear, and you can even see its newly sprouted forks—apparently the wood was still alive when it was plucked.

The chance of being scorched by thunder and not burning in the fire is not an exaggeration.

"How much does this lightning strike wood usually sell for?"

"There are still about a few hundred taels. Ning Wanjun said generously, "However, the price inside the Privy Council is much lower than that on the market, so you shouldn't have too much burden on it." ”

If you put it in a previous life, this is probably a typical template for the perfect boss.

Xia Fan pointed his finger to the ground and secretly drove the streamer.

A bolt of lightning burst from his fingertips and disappeared from view in an instant.

And a few hundred taels of silver also turned into a wisp of green smoke.

As it turned out, he was also able to use lightning to strike wood to cause earthquakes!

The only obvious difference is that the power of the spell has been reduced to an extremely low level. If he used lightning strike wood when facing Ueno Kuji, then it is likely that by the moment of discharge, the opponent's long knife would have already pierced his body.

This kind of seismic technique, let alone drive the electromagnetic cannon.

In other words, if he had practiced the magic with the usual introduction from the beginning, his level would probably be about the same as that of an ordinary new alchemist.

Xia Fan felt that the veil of the world had been lifted a little more.

People's intuitive feelings can transform qi into reality, even if the feeling is not intrinsically connected. At the same time, this does not mean that basic research is meaningless, and the correct understanding of the direction can amplify the effect of transformation.

He was now curious about whether the primer would still be effective if everyone thought that lightning strikes wood could not produce lightning.

"So, what is the experiment you are going to do?" Ning Wanjun hugged her chest and said, "Wouldn't you just want to spend my family's money?"

Not only her, but everyone present saw that Xia Fan lightly cast a seismic spell on the ground, which did not cause any earth-shattering effect, nor did it cause any changes, and a precious lightning strike wood disappeared into invisibility.

Although the princess was generous, she could not accept the act of throwing the silver into the water.

"I just wanted to do a demonstration, and the real experiment is about to begin. Xia Fan said nonsense, "Where do you think the thunder power comes from?"

The question immediately distracted the princess.

"Beyond the Vault?"

"Rain. Luo Youer replied secondly.

"Maybe it'...... God. Akizuki made a gassho movement.

"There are no gods in this world. Li said lightly, "Thunder and lightning are just a celestial phenomenon. ”

"Indeed, even the heavens can be removed. Xia Fan winked at her, "It's all around us, all the time, all the time." ”

"Are you sure?" Ning Wanjun doubted.

"The next thing I'm going to do is verify this scene - without the help of any magic, ordinary people can create and store lightning. ”

In order to minimize everyone's doubts, he did not directly use the finished product to demonstrate, but assembled the test props on the spot.

Xia Fan wants to make one of the simplest Leyden bottles.

He vaguely remembered the story of catching thunder and lightning with a kite.

The key to this is the small bottle attached to the end of the kite string.

If there is no glass bottle, it is replaced by a crystal cup from the princess, wrapped in a thin gold leaf, and grounded with copper wire. The inside is filled with salt water, inserted into a thin copper wire that is coiled around the end, and finally sealed with paper and wax.

It didn't use any strange materials, and the finished product was nothing more than a sealed cup, and no one could have imagined that something so mundane could have anything to do with the thunder and lightning in the sky.

But in Xia Fan's eyes, when two conductors are separated by insulators, their essence has already constituted a most basic capacitance.

After that, it's time to charge the capacitors.

The most primitive charging method is undoubtedly frictional electrification.

Rubbing the jade bracelet with silk allows the charge to be transferred to the silk. When the silk touches the copper wire at the top of the cup, the charge is channelled into the bottle.

These charges will be evenly distributed on the inner wall of the cup due to the presence of salt solution, while the same charge on the outer wall will be repulsed and will flow along the ground line, and more opposite charges will be attracted. Due to the insulator in the middle, the two cannot be neutralized, and they will remain in the form of an electric field, and from the macroscopic performance, the capacitor is charged.

After rubbing it more than a hundred times, Xia Fan looked at the princess, "The thunder and lightning have been stored in the cup." ”

"How can you prove it?" Ning Wanjun's face was full of suspicion.

"Just open the rim. ”

"There won't be any security issues, will it?"

"I said, it's just a little pain. ”

She swallowed and cautiously approached the cup—her body was vigilant despite her disbelief on her face. She held the cup in one hand and slowly approached the rim with the other, and just as she was about to touch the sealing wax, a blue-purple flash exploded between the princess's fingertips and the copper wire at the top.

"Smack!"

The princess snorted softly and subconsciously let go of her hands.

Everyone could clearly see that the cup, which should have been ordinary, shot a brief but dazzling electric light at the princess.
