Chapter 191

The problem that had puzzled him was solved.

The land beneath their feet is indeed a sphere!

And.

It is indeed covered with a boundless ocean!

It's just that...

He soon encountered a problem: how to find this power.

This power can pull so many items; are there things that are not pulled by this power?

In a hurry.

He hurriedly summoned the people of the Great Yan Research Institute to hold a meeting to find this power and its attributes.

At this time.

On the Blue Star.

Qin Mu looked at the rapidly developing Great Yan Kingdom and revealed a satisfied smile.

"I didn't expect someone to develop high-explosive gunpowder so quickly; universal gravitation is also about to be discovered..."

Yan's four national policies were issued very decisively.

Elevating the status of craftsmen, encouraging inventions, publishing the Divine Book...

Various measures.

All made the Great Yan Kingdom move rapidly towards a technological civilization.

27th year of the Great Yan Calendar.

Time flies.

Another year.

In the Great Yan Research Institute.

Yan was leading the people of the research institute to conduct the final simulation experiment.

During this year.

In order to find the power that pulls objects downward, they did countless experiments.

Even...

Publicly offering huge rewards.

As long as someone can find something that doesn't fall, they will be granted official titles and noble ranks, and rewarded with fiefs.

However...

No matter how they searched, they didn't find any items that wouldn't fall.

Even a feather as light as nothing...

If you let go at a high altitude, it will slowly fall and eventually land on the ground.

Secondly.

Rain, snow, hail, and other things at a high altitude of ten thousand feet also seem to fall because of this power.

"Your Majesty, there is news from the Explorer! They did various tests on the back of the earth on the endless ocean, and the result is that all items will fall and point to the ground!"

Soon.

A report from the long-distance fleet came back.

Yan's expression became increasingly excited.

He finally proved the existence of this power!

It is everywhere, always pulling objects to the ground.

Whether it is in the Great Yan Kingdom or on the other side of the spherical earth!

Thus.

The first question of the deity's three questions, the Great Yan Kingdom finally found the answer!

"Next, we must fully study lightning and thunder, as well as the problem of river water and boiled water!"

Yan took a deep breath, and a fire seemed to be burning in his heart.

The Great Yan Kingdom is getting closer to mastering the power of technology...

Getting closer and closer.

28th year of the Great Yan Calendar.

Inspired by the people, the second question of the deity's three questions...

Finally had a direction for research.

Combining various guesses given by the people, the Great Yan Research Institute finally locked the answer to the possibility that the speed of lightning is faster than the speed of thunder.

To verify this point.

The Great Yan Research Institute began to rack their brains to test the speed of lightning and thunder.

But...

Lightning and thunder only appear on rainy days.

And.

They are high in the sky.

It is impossible to test specific data at all.

The sky...

Has always been a forbidden zone for mortals.

Humans cannot set foot in it at all.

Because of this problem, the research on the deity's three questions entered a stagnant stage again.

Helplessly.

Yan could only continue to collect various guesses and opinions from the people.

Seeking methods to test the speed of lightning and thunder.

Finally.

Among the massive guesses, Yan found a constructive guess.

"Lightning looks like light, while thunder seems to be sound..."

After seeing this guess, Yan suddenly realized.

Directly chose to replace thinking.

Began to change ideas and lead the Great Yan Research Institute to conduct speed tests of light and sound.

And then...

Soon the answer was obtained.

"The speed of light is too fast; holding a huge mirror, aiming at a point tens of miles away, reflecting sunlight, it can arrive instantly!"

"While sound has a certain delay; the farther the distance, the slower it is heard..."

In the test.

Yan saw the speed of light for the first time and was amazed.

After this incident, he could finally confirm the answer to the second question of the deity's three questions.

Because the speed of light is faster than sound, lightning is seen by the world first, while thunder is a bit later.

29th year of the Great Yan Calendar.

With the appearance and popularization of various inventions.

The national strength of the Great Yan Kingdom...

Began to climb rapidly.

The appearance of various simple-structured plowing tools saved great manpower and material resources.

The improvement of irrigation methods and fertilizer composting made the yield double.

The national treasury of the Great Yan Kingdom had long been filled with grain.

Fiscal tax revenue had a large surplus.

In this case...
