I will make Qin Shi Huang immortal in the Great Qin Dynasty.

The Laniakea Supercluster in Qin Tian's palm began to shrink, and his field of vision continued to widen.

A massive, fibrous structure, composed of countless superclusters and stretching for nearly 10 billion light-years, appeared in Qin Tian's palm.

That is the Hercules Corona Borealis Great Wall, one of the largest known structures in the universe, spanning over 10 billion light-years and containing tens of thousands of superclusters, hundreds of millions of galaxies, and trillions upon trillions of stars.

Ten billion light-years.

One light-year is the distance light travels in one year. Light travels 300,000 kilometers per second. What does 300,000 kilometers mean? It's enough to circle the Earth seven or eight times.

It circles the Earth seven or eight times in one second, and there are 365 days in a year, which is 86,400 seconds in a day.

Qin Tian's numbers popped into Ying Zheng's mind one by one. For the first time in a daze, he did the math: seven and a half times the Earth per second, 650,000 times a day, and 230 million times a year.

The distance that light travels in a year is equivalent to circling the Earth 230 million times.

He silently repeated the number in his mind: 230 million times.

Two hundred and thirty million rings. And the Great Wall of Hercules and Corona Borealis spans ten billion light-years.

It would take light 10 billion years to travel from one end to the other.

Ten billion years.

He felt slightly dizzy.

"Brother Zheng, this is the observable universe."

"The diameter of the observable universe is approximately 93 billion light-years."

Nine hundred and thirty billion light-years.

The universe itself has existed for no more than 13.8 billion years.

In other words, from the moment the universe was born, light began to travel through the universe. It has been traveling for 13.8 billion years, but it has not even covered one-seventh of the diameter of the universe.

In most parts of the universe, light has not yet reached, and humans will never be able to see any information in those areas.

"There are approximately two trillion galaxies like the Milky Way in the observable universe."

Two trillion galaxies.

What is two trillion multiplied by several hundred billion? Ying Zheng didn't bother to calculate it; he gave up.

This number was beyond his comprehension and beyond his imagination.

The planet he stood on, the empire he lived in, the achievements he built, and the immortality he pursued were nothing but a speck of dust in the face of these two trillion star systems.

"And this is only the observable universe."

Qin Tian emphasized the word "observable".

"Beyond the observable universe, there is the unobservable universe. The observable universe is only a small part of the entire universe that we can see. Because the speed of light is finite and the age of the universe is finite, there is a limit to our vision. Light beyond this limit does not have enough time to reach us, and we will never be able to see those regions."

How large is the unobservable universe?

Qin Tian's smile was somewhat faint, carrying a hint of inexplicable melancholy.

Nobody knows.

Silence fell once again in the hall.

Ying Zheng closed his eyes.

He no longer needs to look at those images.

Those images are deeply etched in his mind and in his soul.

From this day forward, he will no longer be able to see the world the way he used to.

He used to think he was very big.

The territory of the Great Qin Dynasty stretched from the sea in the east to the quicksand in the west, from Beixianghu in the south to Shuofang in the north. All the land under heaven belonged to the king, and all the people on the shores of the land were his subjects.

He is the master of the world, the ruler of all things, and a god who stands at the top of the world, looking down upon all living beings.

But what is that "world"? It's a small piece of land on Earth.

What is Earth? It's an ordinary planet in our solar system.

What is the solar system? It is a small star system on the Orion Arm of the Milky Way galaxy.

What is the Milky Way? It is an ordinary galaxy in the Local Group.

What is the Local Group? It is a tiny, insignificant part of the Virgo Supercluster.

What is the Virgo Supercluster? It is part of the Laniakea Supercluster.

What is the Laniakea Supercluster? It's part of the Hercules Corona Borealis Great Wall.

What is the Great Wall of Hercules and Corona Borealis? It is one of the countless enormous fibrous structures in the observable universe.

What is the observable universe? It is a small part of the entire universe that we can see.

So what is he?

What was the First Emperor of Qin, anyway?

Ying Zheng opened his eyes and gazed at the vast, breathtaking cosmic landscape in Qin Tian's palm. A slow smile curved his lips.

He didn't know these things before, so he was like a frog in a well, with a limited perspective.

Now he knows how vast the sky is, how vast the world is, and how insignificant he is in the universe.

On a cosmic scale, he is not even a speck of dust.

The Earth he inhabits is not even a speck of dust in the observable universe.

His Milky Way galaxy is not even a speck of dust in the observable universe.

The Milky Way galaxy contains 300 billion stars, and the observable universe contains 2 trillion galaxies.

There are two trillion galaxies, and each of them contains hundreds of billions of stars.

He stands on a planet that is one in two trillion times a hundred billion. What is he?

But he was not discouraged.

It is a sad thing that he did not feel his own insignificance.

On the contrary, he felt an unprecedented sense of exhilaration.

Because he still has time, he can go see, conquer, and possess.

The universe is so vast that his imagination cannot contain it.

But it is precisely because the universe is so vast that his ambition has enough room to expand.

His previous goal was to unify the world, but that "world" was only so big.

What is his goal now? He doesn't know. He hasn't figured it out yet.

But he knew one thing: from now on, nothing was impossible.

What is the solar system? What is the Milky Way? What is the observable universe?

He has a national advisor, he has immortality, he has time.

He can take his time.

Ying Zheng stood up, his hands behind his back, gazing at the radiant cosmic image slowly rotating in Qin Tian's palm, his smile growing ever deeper.

"The Imperial Advisor."

"Um?"

"I used to think that the Great Qin was the whole world."

Qin Tian didn't reply, and waited quietly.

"I now understand that the Great Qin is not the world. The Great Qin is merely a speck of dust in the world."

Ying Zheng turned around and looked at Qin Tian.

His eyes were so bright that Qin Tian was slightly taken aback.

"But I don't care."

"The Qin Dynasty is but a speck of dust, and so shall I be but a speck of dust. Dust has its way of living, its ambitions, and its ways of conquering."

"One day, this speck of dust will make the whole universe know its name."

The main hall remained quiet for a long time.

Meng Yi stood to the side, his eyes slightly red.

Looking at His Majesty's domineering demeanor, he felt a burning emotion welling up inside him, as if it would pierce his chest.

Qin Tian looked at Ying Zheng's incredibly bright eyes and smiled.

"Brother Zheng, with your words, I know my journey through time was worthwhile."
