Chapter 339

It was precisely this kind of thing...

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

Thus.

Five years ago.

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

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

The knowledge within was incomparably profound and complex.

He delved into them, self-studying the entire way.

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

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

"The principles of those terrifying cannons and firearms actually also come from 'Chemistry'; is it by relying on these that they defeated us cultivators?"

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

Shen Lian had new insights every day he studied.

As for the spells he practiced before...

He had already forgotten most of them.

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

Riding a steam train was faster than their sword flight.

Spells were simply not needed.

Moreover.

The "Great Yan Law" also stipulated that transcendents were not allowed to use transcendent power at will without permission.

Violators would be punished with a staff, or in severe cases, imprisoned for life.

……

The next day.

After Shen Lian finished a day of labor.

He saw a proclamation posted at the construction site.

It was issued by Yan.

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

Could be granted titles and ranks and rewarded heavily!

Seeing this, Shen Lian became excited all of a sudden.

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 kind of material.

However...

It drew ruthless ridicule from his fellow cultivator companions.

"Forget it, a problem that even the Great Yan Research Institute can't solve, what makes you think you can solve it?"

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

"Studying these things all day, it's not even certain if thousand-mile voice transmission can be realized; however, we can achieve thousand-mile voice transmission into secrets by using spells!"

"Thousand-mile voice transmission, how is this possible? Yan even said he wants people hundreds of kilometers away to hear the sound; at such a distance, at least a seventh-rank cultivator would be needed to do it!"

"……"

Shen Lian ignored the ridicule of his companions.

For him.

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

Every day thereafter.

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 a cultivator.

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

His spiritual sense was very sharp.

His perception of sound was even more refined.

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, all failed.

These materials either had extremely strong sound resistance or did not have the ability for remote connection.

Or...

Simply the sound transmission speed was extremely slow.

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

Half a year later.

His attempts still had no progress.

The rest of his cultivator companions, while ridiculing him.

Also advised him to give up one after another.

Telling him to honestly be a salted fish.

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.

Lightning flashed and thunder rumbled in the sky.

The torrential rain poured down.

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

And ran back in a hurry.

"Boom!"

Suddenly.

A long, narrow white lightning flashed across the sky.

Immediately after.

The roar of thunder exploded in the air.

Seeing this scene, Shen Lian remembered the explanation in the book about light speed being greater than sound speed.

Light speed is theoretically the fastest speed at present.

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..."

Investigating the principles of nature, researching natural science to the fullest.

This point.

Is something the cultivation civilization cannot compare to at all.
