Chapter 69

The problem that had puzzled him before was solved.

The earth beneath their feet was indeed a sphere!

And.

Indeed covered with a boundless ocean!

It's just that...

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

This force could pull so many objects, was there anything that was not pulled by this force?

In a hurry.

He hurriedly summoned the people of the Great Yan Research Institute to hold a meeting to find this force 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.

"Didn't expect someone to develop high-explosive gunpowder so quickly, and universal gravitation is also about to be discovered..."

Yan's four national policies were issued very decisively.

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

Various measures.

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

Twenty-seventh 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.

In this year.

In order to find the force that pulled objects down, they did countless experiments.

Even...

Publicly offered a huge reward.

As long as someone could find something that didn't fall, they would be granted official titles and noble ranks, and rewarded with fiefs.

However...

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

Even a feather as light as nothing...

If you let go of it at high altitude, it would slowly fall and finally land on the ground.

Secondly.

Rainwater, snowflakes, hail, etc., at ten thousand meters in the sky, also seemed to fall because of this force.

"Your Majesty, there is news from the Explorer! They conducted various tests on the boundless ocean on the back of the earth, and the result is that any object will fall and point to the ground!"

Soon.

A report from the long-distance fleet was sent back.

Yan's expression became increasingly excited.

He finally proved the existence of this force!

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 Great Yan Kingdom finally found the answer to the first of the deity's three questions!

"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 was getting closer and closer to mastering the power of technology...

Getting closer and closer.

Twenty-eighth year of the Great Yan calendar.

Inspired by the people, the second 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.

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 497 specific data.

The sky...

Has always been a forbidden zone for mortals.

Humans simply cannot set foot there.

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

Helpless.

Yan could only continue to collect various guess 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 and aiming at a point tens of miles away to reflect sunlight, it can arrive instantly!"

"But 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 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 later.

Twenty-ninth year of the Great Yan calendar.

With the emergence and popularization of various inventions.

The national strength of the Great Yan Kingdom...

Began to climb rapidly.

The emergence of various simple plowing tools saved a lot of manpower and material resources.

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

The Great Yan Kingdom's treasury had long been filled with grain.

Fiscal tax revenue had a large surplus.

In this situation...

The Great Yan invested nearly two-thirds of its fiscal revenue entirely into the Great Yan Research Institute and into rewarding those who made significant inventions.

This caused the public's enthusiasm for invention to rise ever higher.

Every day, hundreds of inventions passed the Ministry of Works' review.

Those with practical value were then mass-produced and promoted nationwide.

It is worth mentioning that...

In this year.

Sun Huyuan, who had previously improved the gunpowder ratio, once again came up with a series of gunpowder-related inventions.

Simulating a bow and arrow, he created steel-structured muskets and iron-pipe cannons.

He completely unleashed the power of gunpowder.

As long as the fuse of a musket was lit, it could fire with a burst of flame.

Ordinary iron armor could not stop a musket's close-range attack at all.

The power of the cannons...

Was even capable of bombarding cities.

No matter how sturdy the city wall, after ten shots, it would inevitably collapse!

Upon witnessing the effects of the muskets and cannons, Yan was ecstatic.

He directly broke protocol and recruited Sun Huyuan into the Great Yan Research Institute, specifically to be in charge of gunpowder research.

As for the muskets and cannons...

They were handed over to the Ministry of Works to begin mass production and arm the entire Great Yan army.
