Chapter 78

Above the statue.

Qin Mu hovered in the void, watching the increasingly aged Yan below.

Birth, aging, sickness, and death.

Are the natural states of ordinary living beings.

"Without realizing it, thirty-eight years have passed..."

Qin Mu sighed softly.

In order to evolve the Blue Star.

He had been using his origin power to accelerate the entire universe.

One day in the outside world.

Equals one year inside.

Calculating the time.

There were only a dozen days left until the Hundred Schools Civilization War.

And Yan...

Had also transformed from an ambitious youth into an old man nearing the end of his life.

Regarding this request made by Yan.

He thought for a moment.

Then left a line of text in the void.

"The speed of light is the ultimate speed in the world and cannot be measured by conventional logic."

"The best method of measurement is the gear method."

Subsequently.

Qin Mu explained this method in detail.

This method.

Was actually something physicists on Earth had conceived in the 17th century, before he had transmigrated.

And below.

Yan looked at the text appearing in the void.

His body suddenly began to tremble.

He kept muttering to himself: "So that’s it, so that’s it..."

After a long while.

He finally recovered from the shock.

After paying his respects.

He hurried away from the Temple, heading toward the Great Yan Research Institute.

"The speed of light is the ultimate speed in the world; guided by the god, we can use the gear method..."

He informed the researchers of the gear method for measurement.

Everyone was suddenly enlightened.

Their expressions became excited all at once.

At this moment.

They finally saw hope in measuring the speed of light!

The thirty-ninth year of the Great Yan Calendar.

After a year of preparation.

On the North Tower.

An experiment to measure the speed of light attracted the attention of the entire Great Yan nation.

The Great Yan Research Institute prepared a lens, and after the sun came out...

They used the lens to focus the light source.

Then.

They placed a gear between the lens and the light source.

Further away on the other side of the lens, they placed another lens and a plane mirror in sequence, with the plane mirror located at the focal point of the second lens.

The light emitted by the light source became parallel light after passing through the gear and the lens, and the parallel light converged at a point on the plane mirror after passing through the second lens.

After reflecting off the plane mirror, it returned along the original path.

Because the gear had gaps and teeth, when the light passed through the gaps, the observer could see the returning light; when the light hit a tooth, it would be blocked.

The time from the start until the light disappeared for the first time was the time taken for the light to make a round trip.

And by using the rotation speed of the gear...

The speed of light could be calculated.

This was a very clever way of converting the speed of light into rotational speed.

Soon.

After multiple measurements.

The Great Yan Research Institute obtained the corresponding rotational speed data.

They began the calculations.

And arrived at a shockingly large value.

"Your Majesty, it has been measured; the speed of light is approximately 300,000 km/s."

Upon seeing this value, Yan could not help but widen his eyes.

It wasn't just him.

Everyone in the Research Institute...

Was terrified.

They had imagined that the speed of light was very fast.

But they had never imagined...

That the speed of light could actually travel nearly 300,000 kilometers in one second!

After a dozen seconds of silence at the scene.

Yan slowly raised his head and looked at the sun in the sky.

He muttered: "The speed of light... is actually this fast?"

At this moment.

He finally understood why the god called light the ultimate speed in the world!

Subsequently.

He took a deep breath and said in a deep voice: "The next issue of 'Great Yan Science' will publish the results of the speed of light research!"

"Prepare the carriage; I am going to the Temple to report this discovery to the god!"

Not long after.

Yan arrived at the Temple and knelt beneath the huge, majestic statue of the god.

He reported the research findings regarding the speed of light.

With this.

The Three Questions of the Gods had all been solved.

In the thirty-nine years since he ascended the throne.

He had been conscientious and diligent.

Having exhausted most of his life, he had finally completed the test set by the god.

"You have done very well."

Above the shrine, a line of text appeared out of thin air.

Yan stared blankly at this line of text, unable to stop his tears from flowing.

This was affirmation from the god.

Affirmation of his achievements over these decades!

And above the statue.

Qin Mu looked at the increasingly aged Yan and sighed softly.

To be honest.

Yan’s development over these years was indeed done very well.

But as time passed...

The aging, sickness, and death of mortals would be unavoidable.

He was considering whether to intervene and help Yan modify his body to extend his lifespan.

After all...

Up to now.

Yan was the most suitable leader for developing a technological civilization.

He could absolutely lead human civilization to continue climbing the technological ladder.

The fortieth year of the Great Yan Calendar.

Yan’s body grew increasingly aged, plagued by various illnesses.

Just as Qin Mu was considering whether to intervene.

Within the Great Yan nation...

A spontaneous wave of medical research had broken out.

"Have you heard? His Majesty is old, and his body is failing!"

"The Great Yan nation cannot do without His Majesty; we must find a way!"

"Medicine, the best way now is to find a way to develop medicine and find a way to extend His Majesty’s life!"

"That’s right! 'Great Yan Science' even discovered bacteria; we can definitely make His Majesty’s body better!!"

"..."

Throughout the entire Great Yan nation.

Countless people spontaneously began to study medicine.

Researching methods to boost physical vitality, enhance resistance, and so on.

In this year.

All the research results published in "Great Yan Science" were in the field of medicine!

The medical level of the entire Blue Star began to climb!

"I didn’t expect Yan’s prestige among the people to be so high..."

Qin Mu saw this scene and was filled with emotion.

This wave of nationwide medical research...

Was not initiated by Yan.

It was entirely spontaneous among the people.

Various theories about medicine emerged like bamboo shoots after a spring rain.

And the level of Great Yan’s physicians also saw a qualitative improvement.

Those famous doctors...

All volunteered to go to the palace to treat Yan.

In the palace.

Yan looked at his graying temples in the mirror.

He was filled with emotion.

He had originally thought...

He wouldn’t live past these few years.

But he hadn’t expected.

The people of the world would spontaneously research medicine.

Countless famous doctors volunteered to treat him and extend his life.

After continuous treatment, the rate of his physical decline slowed significantly.

Moreover.

With the increase in his resistance, his illnesses were not as frequent as before.

"The hundreds of millions of subjects of the Great Yan nation, I will never let you down!"

He took a deep breath.

In his eyes, endless ambition burned.

He had not yet built a vast empire.

There were still so many worlds waiting for him to conquer.

He...

Could not fall yet!

Above the palace.

Qin Mu looked at Yan, whose vital signs were becoming increasingly stable, and smiled.

In that case.

He wouldn’t need to intervene.

Just at this moment.

The system’s voice sounded quietly.

"Ding! The coordinate deduction for the ownerless abandoned world is complete!"

Qin Mu’s eyes lit up.

To deduce this coordinate.

The system had spent a full six days.

And on the Blue Star...

Six years of evolution had also passed.

"I wonder what kind of extraordinary world was randomly found this time..."

Qin Mu’s mind stirred.

Mastering the coordinates of this world, just as he was about to open it...

He sensed an aura from it that even made him feel a bit terrified.

"A civilization world evolved by a middle-tier god?"

His pupils could not help but shrink.
