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

"Brother Zheng, how are you feeling?" Qin Tian's voice came from the side.

Ying Zheng slowly stood up and stretched his shoulders and arms.

He felt that his body was different from before; yesterday's treatment had brought him back to a healthy state from a critical condition.

But today's feeling is different; there's something new inside him.

It flows slowly, endlessly, like a river that has been revitalized, gradually awakening the slumbering land on both banks.

"It feels extremely comfortable." The light in Ying Zheng's eyes revealed his excitement. "My body is full of vitality, as if... I've become much younger."

Meng Yi stood to the side, watching from beginning to end, his eyes wide open.

He doesn't understand.

The Imperial Advisor placed his hand on His Majesty's back for half an hour.

Meng Yi didn't sense anything.

But one thought was crystal clear in his mind: from this day forward, the fate of the Great Qin Dynasty was truly about to change.

Ying Zheng turned around, faced Qin Tian, ​​solemnly clasped his hands together, and bowed deeply.

"Thank you, Imperial Preceptor, for teaching me the method of longevity."

Qin Tian waved his hand: "Brother Zheng, don't be so polite. How are you feeling?"

"I feel extremely comfortable. My body is full of energy, like I'm thirty again."

Qin Tian nodded. The circulation of Yuan energy within the body is itself an excellent way to maintain health.

Ying Zheng's meridians were opened up by his Yuan Power, and the basic circulation was restored. He then completed a full cycle on his own, and the long-blocked energy channels in his body were reactivated. It was natural that he felt comfortable.

"Brother Zheng, from now on, operate according to this method. Operate it every day without interruption. At first, it may feel a bit strenuous and the speed may be slow, but that's okay. Keep at it, and it will become smoother and smoother. With accumulation over time, quantitative change will lead to qualitative change, and you will be able to reach the Yuan Disciple realm."

"Accumulated over time," Ying Zheng repeated these four words, nodding slightly, "How long will it take?"

Qin Tian thought for a moment and said, "It varies from person to person. Some people are fast, some are slow, and it's related to talent, comprehension, and effort. With Brother Zheng's talent and comprehension, plus the foundation I laid by guiding you through the three cycles of the Heavenly Cycle, it shouldn't be too slow. I can't say exactly how long it will take, but it certainly won't be like the few years that ordinary people need."

He paused, then added, "Brother Zheng, cultivation is something that can't be rushed."

Ying Zheng nodded.

"Brother Zheng, let me show you something else." Qin Tian's tone was as if he were sharing an interesting story with a friend over tea, "to broaden your horizons."

He extended his right hand.

Yuan energy surged from his palm and slowly gathered in the void.

It transformed from a chaotic mass into a miniature world with intricate textures.

Inside the main hall, all three people's gazes were fixed on the sphere that was floating above Qin Tian's palm.

That's Earth.

The azure ocean, the yellow-green land, and the white clouds drifted slowly across the surface of the sphere, and even the outlines of the mountains and the course of the rivers on the land were clearly visible.

Ying Zheng saw the places he had flown over the day before.

"Brother Zheng, this is the world we live in. It's called Earth."

Ying Zheng's gaze lingered on the Earth for a long time before slowly rising and landing on Qin Tian's face.

"Are all the places we visited yesterday listed here?"

"They're all here." Qin Tian nodded. "Southeast Asia is here, India is here, the Middle East is here, Ukraine is here, Europe is here, Africa is here, and North America is here."

His fingers lightly touched the globe model, and each spot he touched would light up slightly, as if in response to his touch.

Ying Zheng's gaze followed the movement of his finger.

"I've already covered most of it yesterday, so I won't repeat myself today." Qin Tian removed his hand from the Earth model, but the model didn't disappear; it remained suspended above his palm, slowly and quietly rotating.

Then, a second small ball appeared next to Qin Tian's palm.

That little ball was much smaller than Earth, about a quarter the size of Earth.

Its surface is not azure, but grayish-white, covered with countless pits. There are no clouds, no ocean, only a lifeless gray expanse.

"This is the moon," Qin Tian said calmly. "It's the moon that hangs in the sky every night."

Ying Zheng's gaze suddenly sharpened.

moon?

The moon that countless people look up to every night.

Is the moon a sphere?

A sphere that, like Earth, floats in the void?

Ying Zheng frowned slightly, then quickly relaxed.

He accepted the fact that "the earth is a sphere" yesterday, and accepting that "the moon is also a sphere" today is not so difficult for him.

One ball is a ball, two balls are also balls. Since the earth can be a ball, why can't the moon be a ball?

"The moon revolves around the earth; this system is called the Earth-Moon system," Qin Tian continued, his finger gently moving the moon model, and the gray-white sphere began to slowly rotate around the earth.

Ying Zheng's gaze followed the spinning ball for a long time.

"The moon is a bit smaller than the Earth," Qin Tian said. "It's barren, with no air, no water, and no life can survive on it."

Upon hearing this, Meng Yi couldn't help but interject, "Grand Preceptor, what about those pits up there?"

He pointed to the dense craters on the surface of the moon model, his tone filled with childlike curiosity.

The craters, varying in size and depth, covered the entire surface of the moon, as if someone had smashed countless craters into a grayish-white mud slab.

"Those are impact craters," Qin Tian explained. "There are many rocks of all sizes in the sky called meteorites. When they hit the moon, they created these craters. The moon has no air and no wind or rain, so these craters will never disappear after they are created; they will remain there for billions of years."

Meng Yi nodded thoughtfully.

He memorized this information, though he didn't know how he would use it in the future. But the things the Grand Preceptor said were always reasonable.

Ying Zheng withdrew his gaze from the moon and returned it to Qin Tian's face.

His expression didn't change much, but his eyes told Qin Tian that he was waiting for what was to come.

Qin Tian did not disappoint him.

The Earth-Moon system began to shrink, shrink, and shrink again.

The Earth and the Moon turned into two tiny points of light, and a blazing fireball appeared in the space above Qin Tian's palm.

The fireball was enormous; if the Earth model was a green bean, this fireball was a watermelon.

Its surface was wreathed in blazing flames, and the orange-red light illuminated the entire hall, casting a golden-red glow on the faces of Ying Zheng, Meng Yi, and Qin Tian.

"This huge fireball is the sun."

Ying Zheng paused slightly in his breathing.

The sun, like the moon, is an eternal and unchanging entity that has existed since the beginning of time.

The earth is a sphere, the moon is a sphere, and the sun is a sphere.

The sun is not a disc hanging in the sky, but a huge burning sphere.

"The sun may look small, but that's only because it's so far away from us. Farther than you can imagine." Qin Tian's tone was calm and confident. "How far? From Earth to the sun, it's about 150 million miles."

Ying Zheng's pupils contracted sharply.
