After seven years of fiefdom, Li Shimin asked me to return and become the crown prince.

"this...Is it really a starry sky? Incredible, too incredible!"

Li Chunfeng took the telescope away from his monocular in astonishment, with shock on his face.

After a moment of astonishment, he continued to look through the single hole, and the sky was still repeating:"This is Yaoguang, one of the twenty-eight constellations, this is Tianxuan, and Wei..."

The names of the stars came out of his mouth one by one, but the shock on his face did not dissipate at all, on the contrary, he became more excited.

The stars were extremely clear in his eyes at this moment.

"The moon? There are holes all over it?" Li Chunfeng looked almost crazy, and his tone was somewhat puzzled. Finally, he said,"There is no Guanghan Palace and no Chang'e on the moon!"

"It turns out that the starry sky is so big. Beyond the Milky Way, there are endless"four, six, seven" galaxies, but they are beyond our sight!"

"....."

"Is this the world outside the earth?"

Perhaps because he was too shocked, Li Chunfeng's speech was somewhat incoherent and he didn't know what to say.

Just like that, in the cold night wind���Cheng Feng watched for a quarter of an hour, but he still didn't stop observing.

"Fellow Daoist Li, let me take a look!" Yuan Tiangang was also a little anxious. He didn't understand what Li Chunfeng saw.

However, seeing the shocked expression on Li Chunfeng's face and the telescope he was holding tightly, he knew that Li Chunfeng had seen something incredible....It was something beyond his imagination.

However, after he finished speaking, Li Chunfeng seemed not to hear Yuan Tiangang's words, and still looked at the starry sky reluctantly.

It was like a person seeing a delicious food, or a scholar seeing a shelf full of strange books.

""Li Daoyou!" After another stick of incense, Yuan Tiangang finally couldn't help it and his voice became louder.

In fact,

Li Chunfeng's demeanor really touched his heart. Since he knew Li Chunfeng, he had never seen Li Chunfeng lose his composure like this.

"Brother Yuan, I was too excited just now!"Li Chunfeng finally came to his senses. Looking at Yuan Tiangang's expectant expression, he could only reluctantly hand over the telescope in his hand.

Looking at that expression, it was as if he was giving away tens of thousands of strings of money.

Yuan Tiangang nodded, and regained his original immortal style, slowly taking the telescope.

He was curious about what Li Chunfeng had seen that made him so surprised, but now there were so many people watching, and he couldn't behave as unmannerly as Li Chunfeng.

So Yuan Tiangang took the telescope, followed Li Chunfeng's example and closed one eye, and looked inside through the single-aperture telescope with the other eye.

Eh...

After taking a look, Yuan Tiangang thought he had seen it wrong, so he moved the telescope away to look at the sky again, and then looked through the telescope again!

He repeated it five or six times!

Finally, Yuan Tiangang also became like Li Chunfeng, repeating the names of the stars one by one, from confusion to shock, and then to confusion again.

Time passed little by little!

Yuan Tiangang looked for a full half an hour, and his two wrinkled hands were frozen white, but he still had no intention of moving.

"Zhao Xin, bring the telescope over here!" Li Kuan waved his hand. Yuan Tiangang was already quite old, and it would be terrible if he got sick from the cold.

""You two, come inside and chat, have some hot tea!"

They were asked to sit down, and after drinking some hot tea, they finally calmed down from their shock. They had received too much knowledge today, and were a little confused.

"Prince, is this the Milky Way you saw before?"Li Chunfeng's eyes were still a little dull. No wonder Li Kuan said he wanted to take them to stargazing.

They were superficial. Li Kuan really wanted to take them to stargazing.

"This is just a small telescope. There are even bigger ones in Lingnan that can observe more distant stars!"Li Kuan also took a sip of tea and said slowly,"It's almost the same as you guessed. The ground under our feet is a ball, but the ground under our feet is not the center, but the sun!"

As he spoke, Li Kuan wrote the word"sun" on the table with water. (To read the novel, go to Faloo Novel Network!)

Next, Li Kuan explained the heliocentric theory and the revolution and rotation. The two looked even more incredible.

This was beyond his expectations.

"If the place we are on is a ball, then won't we fall off when it rotates?" Yuan Tiangang frowned. Although he had such a guess, he really didn't know the answer to this question.....

"No!" Li Kuan shook his head:"Because in the universe there is no so-called up and down. Wherever you look up, you can see the starry sky and the universe. Secondly, there is gravity, which attracts people to the earth, just like the sun pulls the nine planets and the earth pulls the moon!"

Li Kuan briefly explained gravity.

However, what he said seemed to be a little beyond the scope. They didn't understand this, but they were still trying to think about the explanation given by Li Kuan.

Gravity?

Gravity?

The sun is the center?

One piece of information echoed in their minds, like a bell, constantly echoing.

"Yes... gravity is like a magnet. If Chunfeng really has such gravity, all our conjectures and speculations will be established!" Yuan Tiangang finally played the advantage of his age at this time, and connected all the words said by Li Kuan. Indeed!

As long as there is the gravity that the King of Chu said, everything makes sense.

Li Chunfeng also began to nod, but then he thought of something:"Your Highness the King of Chu, do you really have a bigger telescope that can see farther?"

Li Kuan just said that he has a bigger telescope that can see farther, how can he not be excited.

In every era, mankind's desire to explore the universe will not stop.

"Naturally." Li Kuan nodded

"1.4 Sir, can I borrow a large telescope to take a look?"Li Chunfeng and Yuan Tiangang's eyes lit up instantly.

"In Lingnan, if you like it, I will send someone to Lingnan to get it tomorrow!" Li Kuan said while looking at the expressions of the two people. Knowing that the time had come, he hesitated and said,"But, this king also has something that he wants your help with!"

Li Chunfeng and Yuan Tiangang looked at each other and said,"I don't know what His Royal Highness the King of Chu wants. I will never refuse anything within my ability!"

Li Kuan had already promised him to use a larger telescope. He could give up such a magical thing, so why not let them help with something?

For the sake of the telescope, even if it was impossible, they would try their best to do it. Li

Kuan smiled slightly, and then slowly said,"Do you two know the art of pulling stars?".
