Peng Cheng hurriedly stepped forward and arched his hand: "But Mr. is looking for Peng?" ”

Zhou Fugui looked Peng Cheng up and down, and said with a slight smile: "My name is Zhou Fugui, and I am here to find Peng Xiucai." ”

When Peng Cheng heard that the person in front of him was Zhou Fugui, the number two person in Xingjing, he was speechless with excitement.

It took a while to come back to his senses, "Peng Cheng came to see Steward Zhou." ”

"No need to be so polite, the president asked me to take you to see him, come with me." Zhou Fugui nodded and smiled.

When Peng Cheng heard that the supreme ruler of Xingjing actually wanted to see him, he immediately became excited again, and hurriedly said, "There is a housekeeper of Lao Zhou." ”

When Peng Cheng followed Zhou Fugui to Zhou Xian's mansion, Zhou Xian was waiting for them in the main hall.

As soon as they entered the main hall, Zhou Xian looked at the polite young man brought by Zhou Fugui.

"President, this is Peng Cheng." Zhou Fugui introduced.

"Peng Xiucai is really a talent, come! Sit down and talk. Zhou Xian looked at Peng Cheng and nodded and said.

Peng Cheng also looked at the supreme ruler of Xingjing, a little surprised by Zhou Xian's youth, and a little nervous.

"Thank you, President." Peng Cheng said a little nervously.

After seeing Peng Cheng sit down, Zhou Xian said, "Do you know why you were invited?" ”

"I don't know, but please make it clear to the president." Peng Cheng arched his hand.

"Your civil service exam score of eighty-nine is the first in the whole, so I want to meet you." Zhou Xian said straight to the point.

Hearing Zhou Xian's words, Peng Cheng said in surprise: "I'm the first? ”

At that time, I was so excited that I didn't pay attention to other people's results.

"Of course, otherwise I wouldn't have come to you, I'm curious how you know so much miscellaneous knowledge." Zhou Xian nodded and asked.

"Since I was a child, I liked to read some miscellaneous books, so I know a little bit about them." Peng Cheng hurriedly said.

"I see, what we Xingjing needs is a talent like you who is proficient in all kinds of knowledge, like the kind of person who only knows the Four Books and the Five Classics, we don't accept it." Zhou Xian said with satisfaction.

"Thank you for looking at it, Peng Cheng will do his best to do things for Xingjing in the future." Peng Cheng said excitedly.

Peng Cheng didn't expect that Xingjing needed talents to learn miscellaneous studies, and it seemed that he had come to the right place.

"What kind of subjects are you good at or interested in?" Zhou Xian asked again.

"I like astronomy more, but the imperial court strictly forbids people to study astronomy, so I rarely mention it to others, and I secretly watch the sky at night alone." Peng Cheng said without concealment. gòйЪ.ōΓg

Hearing that Peng Cheng likes astronomy, Zhou Xian became interested, "What are you studying astronomy for?" Is it for divination? ”

"I don't know anything about observing celestial phenomena and divination, and my night watching celestial phenomena is just a hobby since I was a child, which makes the president smile." Peng Cheng smiled bitterly.

"Okay, with your love for astronomy, how about I make you the director of the observatory?" Zhou Xian asked with a smile.

"What is an observatory?" Peng Cheng asked puzzled.

"An observatory is a building dedicated to observing and studying the sun, moon and stars in the sky." Zhou Xian explained.

"What is the use of studying the sun, moon and stars? A building was also needed to be built specifically for observation. Peng Cheng continued to ask.

"The observatory is too important for humanity." Zhou Xian said affirmatively.

Peng Cheng still didn't understand the meaning of Zhou Xian's words.

"Since you like to watch the sky, do you know why there is day and night? Do you know why there are four seasons of spring, summer, autumn and winter? Do you know why the sun shines? Zhou Xian asked three questions in a row.

Zhou Xian's three questions stumped Peng Cheng, he had thought about why there were problems of day and night before, but no matter how he imagined, he couldn't think of them, so he didn't think about these questions later.

Peng Cheng seemed to know the answer to all this when he heard Zhou Xian's tone, his eyes were full of longing, he looked at Zhou Xian and said, "I don't know about these, please tell me the president." After speaking, he bowed to Zhou Xian.

Zhou Xian looked at Peng Cheng's longing eyes and moved in his heart, and said: "The reason why there is day and night is because the earth where we are is is a big ball, I call it the earth, the earth has been rotating itself, it can be called rotation, when we turn here to the side facing the sun, it is day, and when we turn here to the other side, it is night." ”

Zhou Xian's words exploded in Peng Cheng's mind like thunder, and Peng Cheng's mind was completely shocked, he had never heard this kind of statement, and what he had been instilled was the doctrine that the sky is round and the place is round.

After a long time, Peng Chengcai eagerly asked: "The earth we are on is a sphere, why can't I feel it?" ”

"In fact, it is very simple to prove that the earth is spherical, as long as you go to the beach to observe the passing sailboats, you will find that we see sailboats in the distance sailing towards us, and we can see the sails first and then see the hull, doesn't this prove that the earth is spherical? If the earth were flat, shouldn't the sails be seen with the hull? ”

"I've never been to the beach, I've never seen a sailboat." Peng Cheng said with some embarrassment

"It doesn't matter if you haven't been to the beach, I'll give you another piece of evidence, have you seen the Tengu Eclipse Day and the Tengu Eclipse Moon?" Zhou Xian said with a smile.

"I've seen both the Tengu Eclipse Day and the Tengu Eclipse Moon once." Peng Cheng nodded.

"When the tengu eats the sun and the tengu eats the moon, you observe whether the moon and the sun always have a certain arc, which proves that the earth is round." Zhou Xian explained.

Hearing Zhou Xian's explanation, Peng Cheng began to believe a little that Zhou Xian said that the earth was round.

"Then why are there four seasons of spring, summer, autumn and winter?" Peng Cheng asked again.

"When the earth rotates around its own axis, it is also constantly revolving around the sun, and there is an inclination angle of 23 degrees and 27 minutes between the earth's axis and the orbital plane, so that the direct point of the sun on the earth's surface moves between the Tropic of Cancer and the Tropic of Capricorn, thus forming the four seasons of spring, summer, autumn and winter." Zhou Xian said lightly after taking a sip of tea.

Peng Cheng was stunned when he heard Zhou Xian's explanation, what revolution Zhou Xian said, the southern Tropic of Cancer, he couldn't understand any of them, and he wanted to ask something more.

Zhou Xian asked again: "You don't need to ask again, I can't finish talking about the knowledge in three days and three nights, if you are interested in this, go to our astronomy academy to learn it, and you will know these basic knowledge by then." ”

At this moment, Peng Cheng suddenly knelt down, "Disciple Peng Cheng really wants to learn astronomical knowledge, I want to worship you as a teacher, and I ask Master for permission!" ”

Zhou Xian was stunned, he didn't expect Peng Cheng to worship him as a teacher, Zhou Xian looked at Peng Cheng and thought for a while, and said, "Okay, for the sake of your love for astronomy, I will accept you as a disciple." ”

Peng Cheng was overjoyed when he heard this, and hurriedly kowtowed to Zhou Xian three times, "Master is above, please accept the apprentice's worship!" ”

"Okay, good, please get up." Zhou Xian said with a smile.

"Thank you, Master!"

"You are my apprentice, I didn't prepare any greeting gifts, this revolver will be given to you for self-defense." Zhou Xian said and handed the revolver on his body to Peng Cheng.

Peng Cheng hurriedly stepped forward to take the revolver and said excitedly, "Thank you Master for the reward!" ”

"I'll let the soldiers teach you how to use this revolver later, and you'll be the director of the observatory in the future." Zhou Xian commanded.

"Obey the teacher's orders!" Peng Cheng said respectfully.

Zhou Xian nodded with satisfaction, and said to Zhou Fugui next to him: "Uncle Zhou, arrange a mansion next to my disciple." ”

"Okay, President, I'll arrange it right away." Zhou Fugui agreed.

Peng Cheng, who returned to the inn to pack his things, felt like he was dreaming.

Before going to the master's mansion, he was just a mediocre talent, but now that he has become a disciple of the supreme ruler of Xingjing, the contrast is too great.

Peng Cheng silently remembered Zhou Xian's kindness in his heart, and secretly vowed in his heart that he would report the master's kindness in the future.

The main reason why Zhou Xian accepted Peng Cheng as a disciple was that Zhou Xian was also very interested in astronomy, and he wanted to know where the three-body galaxy he saw when he was traveling and what the mysterious ball of light in his mind was.

It's just that I don't have time to study, so I simply accept a disciple who is interested in astronomy and let him devote himself to research.

Another point is that Zhou Xian sees that this Peng Cheng has a good character and is a gentleman.

As long as he imparts some astronomical knowledge to Peng Cheng in the future, coupled with a telescope, he will definitely be able to make achievements in astronomy.
