Heavenly Dao Formula

Having said that, the lightning strike wood itself cannot produce lightning, but in people's consciousness, it is the proof that the lightning remains in the world, so it has become the best material for the shock technique.

This may seem contrary to logic, but it does not violate common sense.

Xia Fan found a huge mystery appeared in front of him.

To what extent does common sense have to be common to be considered "common sense"?

Utopias obviously don't count, he had already confirmed this during his wanderings, but common sense can be reversed.

When people realize that lightning strike wood has nothing to do with lightning, will this material still be effective?

Having said that, he seems to have never tried the effect of lightning strike wood.

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

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

"It won't... hurt?" Luo You'er asked cautiously.

"Probably a little."

"Eh!"

"Just a little bit." Ning Wanjun showed no fear, "Then what can it prove, or what benefits can it bring?"

"I think it might allow you to see the other side of the world." Xia Fan thought for a while, "If you're lucky, maybe you can master the shock technique on the spot?"

Qiuyue trembled, "Your Highness—"

"Interesting, then come." The princess said without hesitation.

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

...

An hour later, everyone gathered in the small room again.

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

This is the first time he has seen the materials originally dedicated to the shock technique.

This piece of wood is one finger long and two thick, with a complex hollow structure in the middle, as if it had been instantly carbonized by lightning, leaving only intertwined meridians. In order to prevent moths and decay, its whole body has been brushed with tung oil, making it look crystal clear, and you can even see its new branches—it is obvious that the wood still has life when it is picked off.

It is not an exaggeration to say that the chance of being scorched by the thunder and not being burned by the fire is unique.

"How much can this kind of lightning strike wood usually be sold for?"

"About a few hundred taels are still available." Ning Wanjun said generously, "However, the price inside the Privy Council Mansion is much lower than the market price, so you don't have to worry too much about using it."

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

Xia Fan pointed his finger to the ground, secretly driving the streamer technique.

A bolt of lightning shot out from his fingertips, and disappeared from sight in an instant.

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

It turns out that he can also use the lightning strike wood to trigger the shock spell!

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

Such a shock technique is not to mention driving an electromagnetic gun.

In other words, if he used conventional introductions to practice alchemy from the beginning, his level would probably be about the same as that of ordinary new alchemists.

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

People's intuitive feeling can transform qi into reality, even if this feeling has no internal connection. At the same time, this does not mean that basic research is meaningless, and the correct understanding direction can amplify the effect of transformation.

What he is curious about now is, if everyone thinks that lightning strikes wood cannot produce lightning, will this introduction still work?

"So, what kind of experiment are you going to do?" Ning Wanjun hugged her chest and said, "Could it be that you just want to waste my family's wealth?"

Not only her, everyone present saw that Xia Fan lightly cast a shock spell on the ground, which neither caused any earth-shattering effects nor caused any changes. A precious lightning strike wood just disappeared without a trace .

Although the princess is generous, she cannot accept the act of throwing silver into the water.

"Just now I just wanted to be a demonstration, and the real experiment is about to begin." Xia Fan said nonsense, "Where do you think the source of lightning comes from?"

The question immediately distracted the princess.

"Beyond the sky?"

"Rain." Luo You'er was the second to answer.

"Maybe it's... gods." Qiuyue clasped her hands together.

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

"Indeed, even the sky can be removed." Xia Fan winked at her, "It's always around us, every moment."

"Every moment? Are you sure?" Ning Wanjun doubted.

"The next thing I have to do is to verify this scene—ordinary people can create and store lightning without resorting to any alchemy."

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

One of the simplest Leiden bottles that Xia Fan will make.

He still vaguely remembers the story about catching thunder and lightning with a kite.

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

If there is no glass bottle, I use a crystal cup from the princess as a substitute, wrap it with a thin gold leaf, and ground it with a copper wire. The interior is filled with salt water, inserted into the thin copper wire that is wound around the end, and finally sealed with paper and wax.

It doesn't use any weird materials, and the finished product is just a sealed cup. No one can imagine that such an ordinary thing will be related to the thunder and lightning in the sky.

But in Xia Fan's eyes, when two conductors are separated by an insulator, their essence has constituted the most basic capacitance.

After that is to charge the capacitor.

The most primitive charging method is undoubtedly frictional electrification.

Rubbing the jade bracelet with silk can transfer the charge to the silk. By rubbing the silk into contact with the copper wire at the top of the cup, an electric charge is introduced 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-sex charges on the outer wall will be repulsed and will flow away along the grounding line, and more opposite-sex charges will be attracted. Because there is an insulator in the middle, the two cannot be neutralized, and they will remain in the form of an electric field. From a macroscopic point of view, it means that the capacitor is charged.

After rubbing repeatedly for more than a hundred times, Xia Fan looked at the princess, "The lightning has been stored in the cup."

"How to prove it?" Ning Wanjun's face was full of doubts.

"Just open the cup."

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

"As I said, it's just a little bit of pain."

She swallowed, and cautiously approached the cup—even though her expression said disbelief, her body showed full vigilance. She held the cup with one hand, and slowly approached the cup with the other. Just when she was about to touch the sealing wax, a blue-purple flash exploded between the princess' fingertip and the copper wire at the top.

"Snapped!"

The princess let out a soft cry, and subconsciously let go of her hands.

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