Chapter 128

It was exactly this thing...

That defeated the immortal cultivation path he had practiced since childhood and conquered their immortal cultivation world!

Thus.

Five years ago.

He used all the savings he had earned from his labor over the years to buy a complete set of the three volumes of heavenly books from a bookstore.

They were "Mathematics," "Physics," and "Chemistry."

The knowledge in them was incomparably profound and complex.

He delved into them and studied them entirely on his own.

He felt more and more that the three volumes of heavenly books contained vast knowledge.

"So the principle of the steam engine originates from the kinetic energy in 'Physics'? Converting kinetic energy into mechanical energy can unleash such astonishing speed, comparable to an immortal cultivator's sword flight?"

"The principles of those terrifying cannons and firearms actually also come from 'Chemistry'? Did they use these to defeat us immortal cultivators?"

"The 'Mathematics' volume is the most profound; every industry is inseparable from mathematics..."

Every day Shen Lian studied, he had new insights.

As for the spells he used to practice...

He had long since forgotten most of them.

In the Great Yan Kingdom, all kinds of life were extremely convenient.

Riding a steam train was faster than their sword flight.

There was no need for spells at all.

Moreover.

The "Great Yan Law" also stipulated that extraordinary beings could not use extraordinary powers at will without permission.

Violators would be punished with a cane for minor offenses and life imprisonment for major ones.

The next day.

After Shen Lian finished his day's labor.

He saw a notice posted on the construction site.

It was issued by Yan.

Informing all of Great Yan that anyone who could find a material that could conduct sound...

Would be granted official titles and noble ranks and rewarded heavily!

Seeing this, Shen Lian suddenly became excited.

He was originally of captive status.

If he found this material...

Could he get rid of his captive status and become a free citizen?

Thinking of this.

Shen Lian also began to ponder, trying to find this material.

However...

It drew ruthless mockery from his fellow immortal cultivator companions.

"Forget it, even the Great Yan Research Institute can't solve this problem, how could you possibly solve it?"

"Shen Lian, don't forget, you are an immortal cultivator! Do you want to betray the glory of immortal cultivators?"

"Studying these things all day, it's not even certain if transmitting sound over a thousand miles can be realized. However, we can use spells to achieve secret sound transmission over a thousand miles!"

"Transmitting sound over a thousand miles, how is that possible? Yan even said he wants people hundreds of kilometers away to hear the sound. At such a long distance, at least a seventh-rank immortal cultivator would be needed to do that!"

"..."

Shen Lian ignored the mockery of his companions.

For him.

This was a once-in-a-lifetime opportunity to change his status!

Every day after that.

After finishing his prescribed labor, he would try to think and research.

Searching for a carrier that could conduct sound.

In this process, he even began to use the unique spiritual sense of an immortal cultivator.

Before being captured, he was a second-rank immortal cultivator.

His spiritual sense was very sharp.

His perception of sound was even more precise.

He could test the sound conduction performance of materials in detail.

Gradually.

Every day he would test and sense dozens of materials.

But without exception, they all failed.

These materials either had extremely strong sound resistance or lacked the ability for long-distance connection.

Or...

The sound transmission speed was simply too slow.

They did not meet the requirements of the Great Yan Research Institute at all.

Half a year later.

His attempts still had no progress.

While his fellow immortal cultivator companions mocked him.

They also persuaded him to give up.

Telling him to just be a salted fish honestly.

And spend the rest of his life peacefully.

But Shen Lian's gaze was extremely firm and could not be shaken at all.

He continued to search persistently.

Great Yan Calendar Year 77, end of the year.

Southern City.

A super rainstorm arrived.

In the sky, there was lightning and thunder.

A torrential rain poured down.

Shen Lian, who was testing sound conductivity in the wild, had no choice but to interrupt the test.

And hurried back.

"Boom!"

Suddenly.

A long, narrow white lightning flashed in the sky.

Immediately after.

The roar of thunder exploded in the air.

Seeing this scene, Shen Lian remembered the explanation in the book that the speed of light is greater than the speed of sound.

The speed of light is theoretically the fastest speed currently.

Greater than everything in the world.

And sound...

In the air, it can reach a propagation speed of 314 m/s!

Thinking of this.

Shen Lian couldn't help but sigh, "The Great Yan Kingdom's research on these natural phenomena is truly unique..."

Exhausting the principles of nature and studying natural science to the fullest.

This point.

Is something the immortal cultivation civilization cannot compare to at all.

And at this very moment.

A flash of inspiration seemed to pass through his mind.

"Speed of sound and speed of light, the lightning just now..."

Shen Lian turned his head, gazing at the scene of lightning and thunder in the sky.

His heart trembled violently.

The speed of light surpassed sound.

And the lightning just now...

Isn't that the best embodiment of light?

"If I use lightning as a carrier to propagate sound..."

Shen Lian couldn't help but swallow his saliva.

In the pouring rain, his breathing became rapid.

This must be feasible.

Because the phenomena in nature have already confirmed the feasibility of this matter!

This matter seemed to open a brand new door for him.

After returning to his residence.

He hurriedly recorded this conjecture of his.

And in the days that followed, he constantly perfected this conjecture.

"It is definitely unrealistic to want to use lightning as a carrier for sound; lightning is hard to come by and extremely difficult to popularize."

"Then can I find a way... to store lightning and use it to propagate sound?"

"But what can store lightning?"

Shen Lian racked his brains.

And began to turn his research direction toward how to store lightning.

And after his fellow immortal cultivator companions learned of his idea...

They all began to mock him for being obsessed.

Actually trying to store lightning!

Even more so, no one believed he could solve the problem of transmitting sound over a thousand miles.

Gradually.

Throughout Southern City, people heard that there was such a weirdo named Shen Lian among the immortal cultivators.

Actually trying to catch lightning, store it, and use it to transmit sound!

Great Yan Calendar Year 78.

This year.

Shen Lian ignored the cold mockery of others.

But walked firmly along the path he had chosen.

He tried various materials.

Finally...

He found a material called tin foil.

He combined these materials and loaded them on the inside and outside of a glass bottle.

"After a year of observation, lightning can move or stay still. When it moves, it can be transmitted through many items, and when it stays still... it can be preserved!"

Shen Lian looked at the glass bottle he had made in his hand, his mood becoming more and more excited.

This is the principle of the bottle he made.

"Locking" the lightning inside it.

So that it will not dissipate, and storing as much lightning as possible!

"Next, I need to wait for a thunderstorm!"

Subsequently.

Shen Lian began to wait patiently.

This time, he would prove to everyone in Southern City...

That he was right!

Finally.

A month later.

A super rainstorm swept through Southern City again.

In the sky, there was lightning and thunder.

A torrential rain poured down.

"Boom!"

The roaring sound was incessant.

And at this time...

Shen Lian took a large kite and walked out of Southern City.

Arriving at an empty high slope.

On this high slope, a huge metal iron rod stood.

Dozens of meters high.

And the large kite Shen Lian prepared could fly to an altitude of hundreds of meters!

After the people of Southern City learned of this news.

They all held umbrellas and watched from afar.

"Is Shen Lian crazy? Relying on being an immortal cultivator to provoke lightning?"

"Is he not afraid of being struck to death? If his cultivation hasn't reached the third rank, it's impossible to block lightning at all!"

"Everyone look, he placed a large bottle under the iron rod!"

"Could that be the container he made, trying to hold the lightning?"

"..."

The people around stood in the distance and began to mock and joke.

Especially the martial artists, immortal cultivators, giants, and mages.

They all felt that Shen Lian was courting death.

"Boom!"

Thunder suddenly rose in the sky.

And Shen Lian used a spell at this time.

Creating a strong wind.

Making the kite rise higher and higher into the sky.

Higher and higher.

One hundred meters.

Two hundred meters.

Three hundred meters.

At an altitude of four hundred meters.

"Crackle!"

A white light suddenly appeared and lit up in the sky.

Cutting through the sky.

Dragging a long, narrow trajectory.

Its tail...

Was pulled by the kite and struck directly on the kite.

Seeing this, Shen Lian was not shocked but happy.

He hurriedly took a step back.

And tied the tail end of the kite to the iron rod.
