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

The light and shadow in the hall continued to shift slowly.

The sun model that was hovering above Qin Tian's palm had now transformed from a stationary fireball into a star that was moving at high speed.

It traced a bright trail in the void, trailing behind eight planets that seemed to be pulled by an invisible rope, rushing forward with the sun.

Ying Zheng frowned slightly.

Is the sun moving?

He watched helplessly as the giant fireball, carrying the eight planets, drew spiral trajectories in the void.

The circular orbit of the revolution is stretched as it moves through space, weaving into a complex and beautiful spiral curve.

Every planet revolves around the sun, and the sun itself is also moving forward, so the actual trajectory of a planet is not circular, but spiral.

Like a stretched spring, it extends forward in circles around an invisible central line.

"Brother Zheng, the sun isn't stationary either," Qin Tian said calmly. "It's also moving across the starry sky, and at a pretty fast speed."

"Approximately 230 kilometers per second."

The hall fell silent for a moment.

Meng Yi opened his mouth as if to say something, then closed it again, then opened it again.

His mind was racing, calculating something at 230 kilometers per second.

When the Imperial Advisor took them flying, the astonishing speed was already rare in the world.

But the sun runs faster than the imperial advisor? More than twenty times faster?

Meng Yi gave up on the calculations. His brain couldn't keep up.

Ying Zheng's gaze was fixed on the rapidly moving sun model, his pupils reflecting the intense light.

"Where will it run to?" Ying Zheng asked.

"Run towards Vega," Qin Tian said. "But don't worry, it won't reach Vega. The solar system has its own orbit in the Milky Way, just as the Earth revolves around the sun, the sun also revolves around the center of the Milky Way. It doesn't run aimlessly, but runs on a huge orbit, endlessly repeating itself."

Ying Zheng nodded slightly.

He understood this concept; it's the same principle as the Earth revolving around the sun and the moon revolving around the Earth.

Big circles contain smaller circles, and smaller circles contain even smaller circles, layer upon layer, with no one at the center; everyone revolves around something else.

On Qin Tian's palm, the solar system began to shrink, shrink, and shrink again.

That once enormous, blazing, and radiant sun grew smaller and smaller, more and more insignificant in the field of vision.

At the same time, even more light appeared in the void, hundreds of millions of countless points of light.

The sky is full of stars.

A complete and magnificent picture of the Milky Way, with countless stars shining in the void, some as bright as torches, some as dim as dust, some floating alone in the empty space, and some gathering in groups to form huge star clusters.

They come in various colors, some red, some yellow, some blue, and some white, as if someone had scattered a handful of colorful gems in the dark, each one emitting its own unique light.

And in this sea of ​​starlight, there is a huge band of light that stretches across the entire field of vision.

The band of light was formed by countless dense stars, like a river woven from light, flowing from one end of the field of vision to the other, winding and magnificent.

The entire Milky Way appeared in Qin Tian's palm.

Ying Zheng's breath caught in his throat for a moment.

He saw the band of light.

He used to think that the Milky Way was a river in the sky, a place where gods lived, a sacred realm that mortals could not reach.

But now, in Qin Tian's palm, he saw that the Milky Way had transformed into a huge disc-shaped structure composed of countless stars.

It resembles a disc suspended in mid-air, emitting a pale blue light.

The center of the disc bulges outwards, while the edges are flat. Four enormous spiral arms extend outwards from the center, resembling a windmill slowly rotating in the void.

The sun he had just been watching, the sun that carried the eight planets across the sky, had now shrunk to an almost invisible point of light in the complete picture of the Milky Way.

If Qin Tian hadn't specifically marked the location of that light spot, Ying Zheng wouldn't have been able to find it at all.

"Brother Zheng, this is the Milky Way. It's the galaxy where our solar system is located."

Qin Tian gently tapped the tiny marked dot of light with his finger, making it flicker slightly so that Ying Zheng could see its location.

"The solar system is here, on one of the spiral arms of the Milky Way. This spiral arm is called the Orion Arm, near the edge of the Milky Way. Not the center, but... a village, I guess."

Ying Zheng's lips twitched slightly.

His solar system, which he had just thought was incredibly vast, was merely a village in the Milky Way.

"At the center of the Milky Way," Qin Tian's finger moved to the area of ​​greatest light, "is a black hole with immense gravity. It's a celestial body with such strong gravity that even light cannot escape. Anything that gets close to it will be sucked in and never come out. All the stars in the Milky Way, including the Sun, revolve around this black hole. It's like the center of a giant vortex, holding the entire Milky Way within its gravity."

"The solar system revolves around the center of the Milky Way," Qin Tian's voice continued, "How long does it take to complete one revolution? About 250 million years."

Ying Zheng's fingers trembled slightly.

250 million years.

It takes one year for the Earth to revolve around the sun.

The sun takes 250 million years to orbit the center of the Milky Way.

The Earth has rotated 250 million times, while the Sun has only rotated once.

His entire life, on the timescale of the Milky Way, is simply an immeasurable, infinitesimally small quantity that approaches zero.

"By the way, Brother Zheng," Qin Tian suddenly remembered something, and his tone became more serious, "the sun is also a star."

Ying Zheng turned his head slightly and looked at Qin Tian.

"When we look at the stars in the night sky, those twinkling points of light are basically stars. Each one is the same size as the sun, some are larger than the sun, some are smaller than the sun, but they are all essentially the same thing—stars."

Every star is a sun.

Ying Zheng took a slow, deep breath.

He thought those stars were lights in the sky, windows of palaces where gods lived, and decorations used by heaven to adorn the night sky.

He never imagined that every star was a sun.

Every sun may have its own planets, and every planet may have its own mountains, rivers, land, oceans, and all life.

When he looked up at the starry sky, he saw not decorations, but countless suns.
