Chapter 70

The 30th year of the Great Yan calendar.

In this year, various inventions continued to show explosive development.

Among them was one invention...

That played a crucial role in solving the last of the three questions from the gods.

That was the grinding of glass products and the appearance of the magnifying glass!

Someone among the public discovered that after grinding glass, it could magnify objects.

Depending on the angle of the grinding and the size of the convex lens formed...

It could magnify to higher levels.

After Yan inadvertently saw this invention.

He very keenly associated it with the last of the three questions from the gods.

In the three questions from the gods.

Drinking boiled water would not make one sick, but drinking river water...

Was prone to causing diarrhea and various discomforts.

Clearly.

There was a fundamental difference between river water and boiled water.

And because of this...

The difference between river water and boiled water had always been a key focus of the Great Yan Research Institute.

But relying on the naked eye.

One could not see the difference between the two at all.

And the appearance of the magnifying glass.

Provided Yan with another line of thought.

A magnifying glass could magnify objects; could it magnify boiled water and river water?

Thus.

The Great Yan Research Institute began using magnifying glasses to observe river water and boiled water.

At the very beginning.

The magnification of the magnifying glass was too low, and nothing could be seen at all.

Helpless.

Yan could only issue an order for the research institute to increase the magnification of the magnifying glass as soon as possible.

And as the magnification increased...

The observation of river water and boiled water became increasingly clear.

Gradually.

In the river water, Yan actually discovered many tiny, constantly twitching and floating black things!

When he saw this scene, he was startled.

Subsequently.

In the observation of boiled water.

He discovered...

That there were significantly fewer floating black objects in the boiled water.

"Could it be that these things are what make people have diarrhea and get sick?"

Comparing the two phenomena.

Yan muttered: "But what are these black things? Why do they make people sick?"

Research continued.

In the time that followed.

The Great Yan Research Institute continuously increased the magnification of the magnifying glasses.

Finally, they saw the overall appearance of these black floating objects clearly.

They were incredibly ugly, and occasionally there were some small, long, worm-like things.

They looked exactly like the worms that grew in the stomachs of some commoners after they contracted malaria.

With this.

The last of the three questions from the gods was also solved.

Yan was incredibly excited.

He left the Great Yan Research Institute immediately and headed to the temple.

Kneeling on the prayer mat.

He looked at the statue with a pious expression: "Great, all-knowing god, Yan, over the course of four years, has finally answered your three questions..."

Subsequently.

He explained them one by one, stating the discoveries of universal gravitation, the speed of light and sound, and the black objects in the water.

"My life has its limits, but knowledge is limitless; Yan understands this teaching of the god from that day even more now."

Yan's expression was complex, filled with emotion.

In these past few years.

The development of the Great Yan Kingdom could be described as changing with each passing day.

The emergence of various inventions had changed the lives of the commoners, making them increasingly convenient.

And with the in-depth research into the three questions from the gods...

He also felt the vastness of knowledge more and more.

The more he knew, the more he discovered his own insignificance.

Although the Great Yan Kingdom had already solved the three questions from the gods.

But...

Even up to now, there were still many things he had not figured out.

For example, what exactly was the essence of that force pulling objects toward the ground?

Where did it come from?

How powerful was it?

The speed of light is faster than the speed of sound, but exactly how fast is the speed of sound?

And how fast is that speed of light, which can travel dozens of miles in an instant?

The black objects in the water are hideous and terrifying, capable of making people sick.

But why can they make people sick?

Every question was extremely profound.

The current Great Yan Research Institute could not answer them at all.

And above the statue.

Qin Mu was suspended in mid-air, looking down at Yan.

The Yan of today.

No longer had his former arrogance.

He had gained some steadiness and groundedness.

And that innate thirst for knowledge...

Had not diminished in the slightest.

This was exactly what he wanted.

After a moment of thought.

He waved his finger, writing in the void.

"The Great Yan Kingdom has solved the three questions within four years; I am very pleased. I hereby bestow three volumes of heavenly books, titled 'Mathematics', 'Physics', and 'Chemistry'."

Immediately after.

Three books flickering with a faint light appeared out of thin air above the shrine.

Seeing this, Yan was stunned at first.

After he reacted.

His expression became even more excited, staring fixedly at the three volumes of heavenly books before him.

Just a single divine book.

Had led the Ji tribe from barbarism and ignorance to the era of city-states...

This time.

The god had directly bestowed three!

"I kowtow to thank the god for his grace; Yan will definitely lead the Great Yan Research Institute and devote the rest of my life to studying these three volumes of heavenly books!"

Yan knocked his head heavily against the ground.

Qin Mu nodded slightly.

He continued to write in the void: "The power of technology is all contained within these three volumes of heavenly books. If the Great Yan Kingdom can comprehend them, its future achievements will be no less than the extraordinary!"

Yan raised his head.

After seeing this line of text, his body trembled violently.

Extraordinary!

Those two words surfaced in his heart once again.

This time, with the four worlds interconnected.

He had witnessed with his own eyes the immortal cultivators who could fly and escape, the Wu tribe with their terrifying physical bodies, and the magical elves.

All kinds of extraordinary...

Made him, a mere mortal, feel despair!

"Doesn't that mean... as long as my Great Yan Kingdom masters these three volumes of heavenly books, we can conquer those extraordinary worlds in the future?"

His eyes flickered, and he couldn't help but mutter.

Deep in the depths of his pupils.

That ambition, which had been dormant for a long time, surfaced once again.

It quickly took root and sprouted.

Burning brighter and brighter.

One day...

He would lead the Great Yan Kingdom's army to trample over the heavens and myriad worlds, conquering one extraordinary realm after another!

Wherever his gaze reached, it must be the territory of the Great Yan Kingdom!

He would build an unprecedentedly powerful empire!

Above the statue.

Qin Mu looked at the ambitious Yan and was even more satisfied.

Ambition.

Is the original driving force for the advancement of civilization.

"Moreover, it seems it's time to find some civilized worlds for the Great Yan Kingdom to practice on..."

The Great Yan Kingdom now had various inventions emerging one after another.

The combat effectiveness of the Great Yan army had also improved.

It was about time to head to other worlds...

To launch a major military exercise!

Thinking of this.

Qin Mu moved his mind and left the Blue Star.

Returning to reality.

He took out his communicator and dialed Chu Tiange.

"Hello? Principal, it's like this: the creatures I've evolved plan to find some ownerless, abandoned worlds to conduct military exercises and enhance their combat effectiveness. Do you know where I can find them?"

As soon as the call connected.

He stated his purpose directly.

On the other side.

In the principal's office.

Chu Tiange was stunned: "Enhance combat effectiveness? You want to conduct military exercises?"

Qin Mu continued: "Yes, I plan to cultivate an invincible army to prepare for the upcoming Hundred Schools Civilization War."

Chu Tiange then realized.

His eyes lit up.

In the Hundred Schools Civilization War.

One of the competition events involves the world's creatures participating in combat themselves.

He pondered slightly.

Then he said: "Coordinates for ownerless worlds are relatively precious. After all, some relatively complete ownerless worlds are comparable to a source. If you want them, you can go to the Civilization Association to purchase them."

"Depending on the world's rank and degree of abandonment, they range from 100,000 to 3 million world coins."

In the dormitory.

After Qin Mu inquired about the method, he hung up the call quickly.

The Civilization Association is an association specifically for managing various evolved civilization worlds.

In every city, there is a branch.

He glanced at his balance of world coins...

Excluding the money spent on the six thousand world flowers earlier, he had less than 200,000 world coins left.

"Let's go try my luck."

Taking a deep breath.

Qin Mu left Jiangcheng University and walked toward the Jiangcheng branch of the Civilization Association.

One hour later.

Jiangcheng branch.

Qin Mu entered.

Because he had already advanced to a Low-level God, he was soon received by a specialist.

A middle-aged man respectfully served him tea.

"May I ask, sir, what are you looking to purchase at the Civilization Association?"

Qin Mu looked at this middle-aged man.
