Chapter 77

"Your Majesty! We succeeded! It can be preliminarily determined that gravity is about 9.8m/s; it is this force that keeps pulling objects down!"

"As long as the upward force exceeds this force, theoretically, we can even fly in the air continuously!"

After calculating the magnitude of gravity.

Yan looked at the dense, constantly overturned calculation manuscripts in the research institute.

Also feeling incredibly excited.

Taking a deep breath.

He said: "I intend to start a scientific journal, selecting the latest research theories from the Great Yan Research Institute every month, as well as excellent inventions and creations from within the Great Yan Kingdom, to publish them so that the whole world will know!!"

Subsequently.

He looked around at everyone and reminded them: "Gravity is only the tip of the iceberg of the three volumes of heavenly books; you must not be arrogant or complacent, but must continue to work hard and continue to study the heavenly books!"

The people of the research institute became solemn.

They bowed and saluted him one after another: "We will strictly follow Your Majesty's teachings!"

Everyone's expression was full of fanaticism and worship.

They understood very well.

Without Yan, there would be no new look of the Great Yan Kingdom changing with each passing day.

The territory of the Great Yan Kingdom...

Could not have explored the wilderness and the ocean.

Now it has even conquered a world, obtained three giant mines.

And captured 400,000 laborers!

In terms of prestige.

The Yan of today, in the Great Yan Kingdom, is only second to the god.

The 34th year of the Great Yan calendar.

The Great Yan Research Institute continued to study the three volumes of heavenly books, learning mathematics, physics, and chemistry from them.

Creating many novel inventions and creations.

At the same time.

In the 'Great Yan Science' journal, many heavyweight research results were published and announced to the world.

Among them.

The most famous was the systematic introduction of bacteria in river water.

According to the records in the heavenly book, this kind of organism is tiny and is collectively called bacteria.

Some bacteria are harmless to the human body.

Some bacteria, however, spread diseases!

And with the deepening research into 'Physics', one of the three volumes of heavenly books.

A high-magnification microscope was developed.

Through the microscope.

The people of the Great Yan Research Institute discovered dozens of types of bacteria for the first time.

And classified these bacteria and gave them names.

At the same time, they made various petri dishes to cultivate and observe the bacteria.

The habits and hazards of these dozens of types of bacteria...

Were all clearly summarized and explained.

They even believed that human illness was very likely caused by these bacteria.

This series of theories was published in the 'Great Yan Science' journal.

Shocking the entire Great Yan Kingdom!

The 35th year of the Great Yan calendar.

The Great Yan Research Institute formulated another series of experiments, attempting to solve the second of the three questions from the gods.

The speed of sound and the speed of light!

Before this.

They only knew that the speed of light was faster than the speed of sound.

But exactly how much faster...

No one knew.

After hundreds of failed experiments and adjustments.

The Great Yan Research Institute finally found the best way to calculate the speed of sound.

Let a person stand at the very top of the North Tower.

Looking at a cannon firing ten kilometers away.

When hearing the roar of the cannon, record this time point.

Testing this cycle hundreds of times.

Obtained hundreds of different time data.

Then...

From these times, divide by the distance between the two places, and take the average value.

Concluding that the speed of sound is about 343m/s.

The appearance of this result.

Made Yan overjoyed.

He directly ordered people to publish it in the 'Great Yan Science' journal and announce it to the world.

Subsequently.

The ambitious Yan.

Directly formulated the next topic for the Great Yan Research Institute: calculating the speed of light!

"Within one year, the speed of light must be calculated!"

Immediately after.

The Great Yan Research Institute invested in the research and measurement of the speed of light.

And Qin Mu was standing outside the Blue Star.

Watching this scene.

The corners of his mouth couldn't help but twitch a few times.

After conquering the martial arts civilization.

In these three years 0

The Great Yan Research Institute had indeed achieved amazing research results.

Whether it was bacteria, or the calculation of gravity, or the calculation of the speed of sound, there had been great progress.

The technological civilization was also developing slowly.

But...

The speed of light is simply too terrifying.

Ordinary methods could not possibly measure it.

Even the technological universe he evolved now had a diameter of 3 million kilometers.

But for light...

It was only a distance of a few seconds.

"Within one year, wanting to calculate the speed of light is almost impossible..."

Qin Mu shook his head helplessly.

The 36th year of the Great Yan calendar.

One year passed.

The Great Yan Research Institute tried over a thousand measurement methods for the speed of light.

As a result...

Without exception, all failed.

At first.

They intended to erect a giant mirror on the North Tower.

Then, project light to a point fifty kilometers away.

To time the arrival at a distance of several dozen kilometers.

To calculate the time it took for light to travel those fifty kilometers.

But...

No matter how they measured it, the light arrived almost instantaneously!

It was simply impossible to calculate the time it took to traverse the path.

"Your Majesty, the speed of light... is too fast. We have tried over a thousand methods, yet we still failed."

The researchers looked at Yan, their faces full of bitter smiles.

Yan frowned deeply.

He stared at a mirror.

In this past year, he had learned of over a thousand measurement methods.

Every possibility had been attempted.

Yet not one could measure the speed of light.

"My time... is running out..."

After a long while.

He looked at his own graying reflection in the mirror and sighed.

That’s right.

He was already old.

Since usurping the throne at twenty-eight.

Now, he was nearly sixty-five.

Especially in this recent period.

He felt increasingly powerless, his physical strength declining.

Therefore.

He had been urging the Research Institute to accelerate their progress.

And over these years.

With the deepening of various studies.

The other questions in the Three Questions of the Gods had all been solved and answered.

The only one left unsolved...

Was the speed of light!

"The Three Questions of the Gods are a test from the gods to me; in my lifetime, I must solve them!"

Yan clenched his fists, thinking silently in his heart.

Thus.

He looked at the researchers again: "Continue the research! Although the speed of light is fast, there must be a way to measure it!"

The speed of light.

Had become an obsession deep within his heart.

The thirty-seventh year of the Great Yan Calendar.

The research atmosphere advocating for science grew increasingly intense.

Within the Great Yan nation, outstanding achievements were made in every field.

In the field of military weaponry.

Sun Huyuan, who invented cannons and muskets...

Through the study of the Heavenly Book volume "Chemistry."

Purified the concentration of gunpowder, greatly increasing its power.

At the same time.

He improved both muskets and cannons.

Creating muskets and cannons that could be fired directly by pulling a trigger, without needing to be lit.

Making them more convenient for combat.

And civilian inventions sprang up like bamboo shoots after a spring rain.

Tens of thousands of inventions emerged.

Many civilian theoretical submissions were also published in the special edition of "Great Yan Science."

The wheel of civilization was rolling forward.

However...

For Yan.

The measurement of the speed of light, which he cared about most...

Had made no progress at all.

After countless attempts, the researchers were unable to determine the specific value of the speed of light.

They could only infer the lower limit of the speed of light.

It could circle the Blue Star beneath their feet more than ten times in one second.

It had reached an incredible degree.

But this was not what Yan wanted.

What he wanted...

Was a specific value, like the speed of sound at 343m/s.

The thirty-eighth year of the Great Yan Calendar.

The Great Yan nation was thriving and becoming increasingly powerful.

But in the research of the speed of light...

There was still no progress at all.

And this year, Yan was already sixty-six.

"Could it be that in my lifetime, I truly cannot completely solve the Three Questions of the Gods?"

Looking at his increasingly aged self in the mirror.

Yan let out a long sigh.

After much hesitation.

With faltering steps, he arrived at the Temple.

Kneeling beneath the statue of the god.

His gaze was as pious as it had been decades ago.

"Yan pays respects to the great god."

"Yan has come this time to ask the god how one can determine the specific speed of light."

He prostrated himself on the ground.

And asked this question.

He had originally wanted to rely on the wisdom of the Great Yan nation to solve the test left for him by the god.

But...

Over these years, he felt increasingly old and powerless.

He worried that he would not live to see the day the speed of light was measured.
