Chapter 208

Without exception, all failed.

At first.

They planned to set up a huge mirror on the North Tower.

Then radiate light to fifty kilometers away.

Calculating the time point dozens of kilometers away.

Calculating the time required for light to pass through these fifty kilometers.

But...

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

It was impossible to calculate the time it took to pass through the path.

"Your Majesty, the speed of light... is too fast; we have used thousands of methods, but we still failed."

The people of the Research Institute looked at Yan, smiling bitterly.

Yan frowned tightly.

Staring at a mirror.

In this year, he knew all of the thousands of measurement methods.

Every possibility had been tried.

But none could measure the speed of light.

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

For a long time.

He looked at himself in the mirror, who was already gray-haired, and sighed.

That's right.

He was already old.

Since usurping the throne at 28.

By now, he was nearly sixty-five years old.

Especially in recent times.

He felt increasingly powerless and physically declining.

Therefore.

He had been urging the Research Institute to speed up the research progress.

And over these years.

With the deepening of various research.

Other questions in the three questions from the gods had all been solved and answered.

The only one that hadn't been solved...

Was the speed of light!

"The three questions from the gods are the god's test for me; I must solve them in my lifetime!"

Yan clenched his fists, thinking silently in his heart.

Thus.

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

The speed of light.

Had already become an obsession deep in his heart.

The 37th year of the Great Yan Calendar.

The atmosphere of scientific research became stronger and stronger.

In the Great Yan Kingdom, outstanding achievements were made in various fields.

In the field of military weapons.

Sun Huyuan, who invented cannons and muskets...

Through research into the 'Chemistry' volume of the Heavenly Books.

Purified the concentration of gunpowder, greatly increasing its power.

At the same time.

He improved both muskets and cannons.

Creating muskets and cannons that didn't need to be lit, but could be fired directly by pulling a trigger.

Making combat much more convenient.

And inventions among the common people emerged like bamboo shoots after a spring rain.

Tens of thousands of inventions emerged.

Many theoretical submissions from the public were also published in the 'Great Yan Science' journal.

The wheel of civilization was rolling forward.

However...

For Yan.

The measurement of the speed of light that he cared about most...

Had no progress at all.

The people of the Research Institute tried countless attempts, but in the end, they couldn't determine the specific value of light.

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

In one second, it could circle the Blue Star beneath their feet more than ten times.

It had already reached an incredible degree.

But this was not what Yan wanted.

What he wanted...

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

The 38th year of the Great Yan Calendar.

The Great Yan Kingdom was thriving and becoming increasingly powerful.

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

There was still no progress.

And this year, Yan was already sixty-six years old.

"Is it true that I cannot completely solve the three questions from the gods in my lifetime?"

Looking at himself in the mirror, who was getting older and older.

Yan sighed long.

After hesitating for a long time.

With staggering steps, he came to the temple.

Kneeling beneath the statue of the god.

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

"Yan, greetings to the great god."

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

He bowed long on the ground.

Asking this question.

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

But...

Over these years, he felt his body getting older and his strength failing him.

Worried that he wouldn't live to see the day the speed of light was measured.
