"Are you finished?" Zhou Mo stopped playing with the glass pieces in his hand, raised his head and asked.

"The villain has finished speaking. Young Master, please go quickly. The clan leader is really angry. If you don't go, something big will happen."

Zhou Mo said: "It doesn't matter. You go back and tell your uncle first that I have something important to do and I really can't leave. Please give him a few days of grace. At that time, Zhou Mo and I will visit him and apologize to him."

"This is inappropriate." The servant said anxiously, "How big of a thing can it be, bigger than the clan leader?"

Zhou Mo smiled and said, "I'll keep it under wraps for now. You go back and tell your uncle that I'm going to give him a surprise so that he can calm down first."

"I know, that villain has to leave first." The servant had no choice but to accept the order and leave.

Because of his uncle's urging, Zhou Mo also wanted to speed up the progress, so he paid the jade craftsmen three times their wages that night. After a busy night, although some materials were damaged, two circular plano-convex lenses that met the requirements were finally successfully ground.

Early the next morning, after another polishing process by the polisher, the two circular plano-convex lenses, one large and one small, were finally completed. When placed under the sun, they were crystal clear, with a slight green light on the sides.

Although if you look carefully, you can still see some bubbles and impurities inside, it is definitely enough.

By focusing the sun, Zhou Mo used a lens to burn an ant on the ground to death, and also accurately measured the position of the focus of the lens. After simple calculations, he could calculate the diameter and length of the lens barrel.

Zhou Mo found a goldsmith with excellent skills in the clan and asked him to make two gold tubes about one foot in length out of pure gold to use as the lens tubes of the telescope.

The reason why gold is used is because gold is soft and can be processed into any desired shape as long as the master is skilled in craftsmanship.

For example, if you want to perform micro-processing on the two ends of the inlaid lens, fine-tuning the angle and position of the lens to make the image clearer, using gold as the raw material, it is relatively easy to modify.

The eyepiece can also be slightly rounded to avoid scratching the corners of the eyes.

Of course, the main reason is because there is no shortage of money.

Two days later, the telescope was finally completed, and after half a day of debugging, the image finally became clear.

Zhou Mo couldn't wait to try it out.

Although the field of view is not wide, the brightness is not high enough, the halo and chromatic aberration are also obvious, and the hand-held observation jitter is also very severe.

However, there is a bird sitting on a tree dozens of meters away, and it is really clear to see.

Zhou Mo suppressed his inner excitement and hurriedly found someone to make a wooden stand. He used bamboo of suitable size and cut it into a semicircle. He stuck the telescope tightly on it at the front and back positions and fixed it firmly with ropes.

I also used yellow paper to make a simple hood on the objective lens to reduce light interference and improve imaging brightness.

Although this is not very beautiful, and it is not very convenient to move, it frees both hands and can be placed on the table. When observing, the stability of the picture has been significantly improved.

In the evening, when the sky was getting dark, Zhou Mo enthusiastically took his telescope to his uncle's mansion in the western suburbs of the county.

As soon as he entered the door, the servant saw Zhou Mo coming and said, "Sir, you are finally here. I will quickly inform the master."

"No need. Uncle should still be in the attic, right?" Zhou Mo stopped him and said.

The servant said: "Here you are. Master's habits are clear to you. At night, as long as the weather is fine, you always go to the attic and stay for half a day."

"I'll go up by myself. You don't have to worry about it."

"Yes." The servant agreed and retreated.

Zhou Mo looked up and saw that the attic was high, with candlelight shining slightly on the top. He climbed up the rotating wooden stairs in the building, climbed halfway, and looked down, his pupils were shadowy and deep.

I even feel a little weak in my legs.

This was his favorite place to play when he was a child. Even though it was a bit dangerous, the thrill of his heartbeat and the sense of accomplishment that came from having the courage to overcome the danger made him immersed in it. He still remembers it clearly.<

/p>

Above the attic, the wind is stronger than below.

Zhou Qun was standing on the edge of the railing with his hands behind his back, raising his head at a forty-five-degree angle, concentrating on looking up at the stars, his robes swaying in the wind, and he looked quite magnanimous.

The weather is sunny today, with the first quarter moon hanging in the sky, dense stars, and the Milky Way flowing by. It is relatively rare in Sichuan, and Zhou Qun does not want to miss this opportunity.

"Uncle and nephew are here to see you." A voice came from behind.

Hearing this familiar voice, Zhou Qun became furious.

I personally ordered someone to come to him two days ago, but he dared to disobey and disrespect me.

As for the gift he mentioned, Zhou Qun doesn't care about it at all.

What is a surprise? It's just an object. No matter how surprising it is, what else can he have that Zhou Qun hasn't seen before?

To put it bluntly, even if it is something from Liu Chan's palace, as long as Zhou Qun wants it, he can find a way to get it right away.

What surprises can he have for Zhou Mo?

Moreover, what Zhou Qun hates the most is others disturbing him when he is observing the sky and thinking about the universe.

He understands Zhou Mo, just as Zhou Mo also understands him.

He knows that Zhou Mo certainly knows what he hates most.

Either she never comes, she refuses to come when called, but she chooses this time to come. What else could be the reason other than to deliberately anger him?

Zhou Qun suppressed his anger and turned around, only to see Zhou Mo's bright and excited smile.

This smile is exactly the same as when he was a child, when he was mischievous and his tricks succeeded!

The anger in Zhou Qun's heart suddenly became even greater.

However, now that he is an adult and is still a high-ranking official in the court, can he still take off his pants and beat his ass like he did when he was a child?

The anger in his heart was suppressed by Zhou Qun.

"Uncle, look what good things my nephew has brought you."

Zhou Qun threw up his sleeves and said angrily: "Don't look!"

"Uncle, don't be angry. You must take a look at the good thing that my nephew finally made. Well, what should I name it?" Zhou Mo pondered, "If you have it, let's call it Tianji Tube. After all,

, you can get a glimpse of the secrets of heaven with it, and the mysteries are endless."

"What? Heaven's secret cylinder? You are really ignorant, fearless, and extremely arrogant. I have been observing the astronomical phenomena for decades, and I still dare not talk about the secrets of heaven. How do you know what secrets are?" Zhou Qun said angrily.

Zhou Mo ignored him and just placed the shelf on the ground, fixed the gold "celestial cylinder" on the shelf, put on the hood, bent down again, made simple adjustments, and pointed it at the moon.<

/p>

In the field of vision, the craters on the moon are clearly visible.

Although he had already expected it, at a glance, Zhou Mo's heart was still filled with excitement at the damn charm of science.

He couldn't wait to show his uncle a look.

Zhou Qun looked on, feeling baffled. He managed to rely on years of self-cultivation to secretly suppress the anger in his heart, so as not to explode immediately.

"Come on, uncle, look through this hole."

Zhou Qun glanced at Zhou Mo doubtfully.

"Uncle, look at the look in your eyes. I wonder if my nephew can still deceive you. Take a look. It's just that the mystery in this mirror is too shocking. After seeing it, uncle must be calm and don't get too excited."

Seeing Zhou Mo's determined look, Zhou Qun also became curious and said to himself: "Just have a look. If it's a prank again, no matter how important the court officials are, I won't break your legs."<

/p>

Half convinced and half doubtful, he also imitated Zhou Mo's posture, lowered his waist and leaned in front of the eyepiece.

Zhou Mo commanded from the side: "Uncle, close the other eye."

"The eyes can be a little closer to see more clearly."

"Don't move your hands randomly. If you move your hands, you won't be able to see clearly."

"Uncle, what did you see?" Zhou Mo asked impatiently.

Zhou Qun did not respond to Zhou Mo, but his breathing became faster and faster due to excitement.

Hearing his uncle's rapid breathing, Zhou Mo thought to himself, sure enough, his uncle may refuse anything, but it is absolutely impossible to refuse this.

Zhou Qun suddenly said: "This is... yes, that's right, that's it. Sure enough, sure enough, my guess was right."

"Uncle, what is right?" Zhou Mo asked.

"The shape of the moon is not a round cake, but like an egg. I have guessed this many years ago, but I can't be sure."

Zhou Mo smiled and thought, the moon and the moon are common knowledge that every three-year-old child knows in modern times. My uncle has been watching the celestial phenomena for half his life, but he is just guessing, but he can't draw a conclusion.

Sure enough, if a worker wants to do his job well, he must first sharpen his tools.

The uncle said again: "It's wrong, it's still wrong."

"What's wrong?"
