Xiao Yuehua washed out a bowl of soapy water, then twisted a few circles of bamboo strips and fixed them together. She dipped it in a little soapy water, stood it up facing the wind, and immediately blew out a series of bubbles.

Xiao Yuehua said proudly: "Look, isn't it fun?"

Li Dan nodded vigorously and begged, "Senior Sister, let me try it too."

"Okay, this is for you. I'll go make a few more." Xiao Yuehua handed the bamboo ring in her hand to Li Dan, and ran over to start tinkering again.

"The reason why we can see the world is actually with the help of light. An object must emit light for us to see it."

Wang Zhen, Li Xian, Li Xian, and Wang Pingan sat in front of Wang Zheng. After recording, Li Xian looked up and asked, "But many objects don't emit light?"

"Reflection. When light shines on an object, the object will block the light back, which is actually equivalent to shining. The flatter the object, such as a mirror, the greater the intensity of reflection."

Li Zhi looked at the sun again before handing the telescope to Li Xian and said, "Take them to one side to watch. Remember not to watch for too long at a time. Take turns."

Li Xian and a few others looked at each other, not knowing what expression to give. They were not shocked at all, as they had already gotten used to it.

Wang Zhen laughed cheerfully and said, "Why not let me try it first?"

Wang Zheng took out a telescope again and said with a smile, "This is made by me using black crystal. You can use it to look at the sun for a while, but remember not to use it for too long. You need to take a break every ten breaths at most."

As Li Zhi was about to move the telescope toward the sun, Wang Zheng quickly stopped him, saying, "Your Majesty, you cannot do that."

Li Zhi was still frightened, and as he looked at the telescope in Wang Zheng's hand, he became a little hesitant.

Wang Zheng smiled and said, "Your Majesty is the master of this world. As for the affairs of heaven, let them be. In fact, in my opinion, the title of Son of Heaven is often a burden.

The title of Son of Heaven was okay during the Han Dynasty, but nowadays, only foolish men and women take the title seriously. In the eyes of aristocratic families and Confucianists, it is just that.

Hearing this, Li Zhi nodded. This was indeed the case. It would be strange if Wang Zheng gave a direct answer at this time.

In the past, there have been cases where people used low-power telescopes to look at the sun and ended up with eye burns, decreased vision, or even blindness. If you look at the sun with this high-power telescope, you will probably go blind immediately.

Li Zhi asked anxiously, "What did the third brother see?"

Li Zhi was stunned for a moment, then he took the telescope from Wang Zhen and looked at the sun. After a while, he put down the telescope and frowned in thought.

Li Xian was watching with envy and couldn't help asking Li Zhi, "Father, can you show me?"

Li Zhi raised his eyebrows and smiled, "What new gadgets have you come up with, or what new discoveries have you made? Do you want to show them to me?"

Li Zhi took the telescope and looked into the distance, then nodded and smiled, "It's quite far, but I don't know if I can see the moon."

Wang Zheng smiled and said, "I would like to say that the blazing sun is like a fireball, while the moon and stars themselves do not emit light, they just reflect the sun's light. The sun, moon and stars should all be like our earth, very large spheres."

Li Xian frowned and said, "But the black stone is polished very smoothly and doesn't reflect light very much?"

Wang Zheng nodded and explained, "It is precisely because I have seen it that I say the sun is a big fireball."

The waiting was torment. During the day, Li Zhi would occasionally look at the sun with a high-power telescope. As soon as the sun set, he would immediately become irritated and pace back and forth on the deck with the telescope in his hand.

If it were midsummer, the sun and the moon would appear in the same sky. However, the moon came out a little late in early summer, which made Li Zhi very anxious. Finally, he sat down next to Wang Zheng and sighed helplessly, saying self-deprecatingly: "I am a fake emperor. At least I can't do anything about the sun, moon and stars in the sky."

Wang Zheng nodded and praised: "That's true. No light means darkness, so black doesn't reflect light. The reason why we can see black is just because of the contrast with the surroundings."

Wang Zheng smiled and took out a telescope, saying, "This is something I made slowly because I was bored recently. Today is the fifteenth day of the lunar month, the sky is clear and there is no wind, so I can take a good look at the moon."

After the kids left with their telescopes, Li Zhi asked Wang Zheng, "Has the steward seen it?"

Wang Zhen looked at his teacher and saw that he was smiling and silent, so he replied, "I saw a big fireball with black spots on it."

Li Zhi nodded and then asked, "What are those black spots on it? Don't tell me that they are firewood, Steward."

If it were really useful, there would be no change of dynasties.

Wang Zhen took the telescope handed to him by the gentleman, first looked around, then slowly moved it to the edge of the sun. After finding that there was no problem, he looked at the sun. After a while, Wang Zhen put down the telescope, frowned and began to think.

"I don't know either. Perhaps if I watch it for a while longer, I might be able to get some guesses, but they may not be the correct answers."

Li Zhi was stunned for a moment, then immediately put down the telescope and said with a wry smile: "I was careless."

Li Zhi came over and asked, "What do you want to prove by saying this, Chief Steward? I can't wait any longer."

Then Li Zhi sighed: "I didn't expect the sun to be a burning fireball. Now I am even more curious about the moon at night."

Li Zhi laughed and said, "Haha, since the chief steward doesn't believe in ghosts and gods, it doesn't matter what you say. But I can't just do what I want. I have to put up with many things even if I have to deceive myself. After all, we have been here for so many years, and I can't change suddenly."

Wang Zheng smiled without comment, raised his hand and pointed to the sky. He didn't know when the moon came out.

When Li Zhi saw the bright full moon in the sky, he quickly put the telescope to his eyes and looked at it, making “tsk tsk” sounds with his mouth as he looked.

After a long while, Li Zhi put down the telescope and asked Wang Zheng, "Have you ever used this telescope to look at the moon?"

Wang Zheng shook his head and smiled, "No, after all, the nights along the way are always cloudy."
