In a corner of the residence, Bo Zhengtong, the head of Bazhou, was talking to a middle-aged man. The intense conversation could be described as a debate. Yuwen Wen, who arrived in a hurry, was quite surprised to see this scene because he saw Zheng Tong having a "talk" with others for the first time.

Who is Zheng Tong? The grassroots official of Liang State, and the "Ma Yi Shen Xiang" on the streets of Jiangling, the capital of the country, is based on "professional qualities". It is a omniscience of astronomy and geography, and it is clear and clear, regardless of whether it is clear rules and hidden rules.

When you talk to people and talk to ghosts, your tongue skills are so sharp, and you can also observe words and expressions, and you can understand people's hearts with great ability. Your acting skills are superb. You are already the domineering person in the "Ma Yi Divine Appearance".

However, today Yuwen Wen actually saw Zheng Tong's mood fluctuations. The other party's verbal battle was not lost to others except to lose to him.

Many people will involuntarily make small movements when they are emotionally excited. Yuwen Wen's ears will involuntarily move when they are emotionally excited. He found that Zheng Tong would clench his fists when he is emotionally excited, and repeatedly clench his left hand, relax, and clench his clench.

This is how Zheng Tong is performing now.

Yuwen Wen was quite curious about the man. He felt that it was definitely not easy for those who could quarrel and make Zheng Tong lose his advantage. He gained the upper hand because Zheng Tong could be refuted by the knowledge of later generations, but now this person is so good, I am afraid that there is real information.

As the saying goes, "It depends on the owner to beat a dog." Although Zheng Tong is not Yuwen Wen's dog, he is also his subordinate. When he is in trouble, the boss will naturally have to cover him. Yuwen Wen, who had just successfully destroyed the three views of the alchemist, joined the battle with confidence:

"Zheng Zhubo, I wonder who this person is?"

"Assistant Liu, Zhang Zixin, Qinghe, lived alone in seclusion on the island for more than 30 years. How did the armillary sphere bring to the island? The armillary sphere requires hydraulic power to operate. Where does the hydraulic power come from just the island? Is it tidal power?" Zheng Tong asked, not realizing that Yuwen Wen had arrived nearby at all.

"Zheng Zhubo, this matter is a subtle and why bother to bother me? Liu, why should Chen Xing not see him?" The middle-aged man asked back, but did not notice that there was one more person around him.

"No, as the saying goes, a slight mistake can lead to a thousand miles of mistakes. If Zhang Zixin's armillary sphere is nothing, how can his observations be credible?"

"This is a big mistake! What Zhang Zixin said, "The sun goes after the vernal equinox will be slow, and the autumnal equinox will be fast." Isn't it right? Also, "The moon in the new moon will be in the sun path, and the sun will be eclipsed. If it is outside the sun path, even if it is not a loss," said Zheng Zhubo, who doesn't know?"

"These two things Zhang Zixin said are not false, but Chen Xing's 'see', and 'fu' may not be as he said. Zu Wenyuan Zeng said..."

A gust of wind blew, rolling up fallen leaves on the ground. Yuwen Wen became messy in the wind, not because he was ignored by the two, but because he basically couldn't understand the content of the debate between the two sides.

It is said that it is basic because Yu Wen Wen at least understands some of the nouns quite well, but it is these nouns that make him regret not being the first, and he feels that he shouldn't have come here and is involved in the debate for no reason.

Zheng Tong called the other party "Assistant Professor Liu", so the middle-aged man should have the surname Liu. As for the assistant teacher, as the name suggests, it is similar to the assistant teacher in later generations, and Yuwen Wen already feels that it is not good.

Nowadays, those who can be called assistants can only be teachers who teach knowledge in the Imperial Academy and serious scholars. According to popular sayings in later generations, they are academic masters second only to great scholars. No matter how "unique" Yuwen Wen is, he cannot argue with academic masters second only to great scholars.

Assistant teaching is a position established by the Imperial Academy. The Imperial Academy is the highest institution of learning in a country. The Imperial Academy of Zhou State has six doctors, who are the lower doctors, and four destinies; six assistants, who are the higher scholars, and three destinies.

It’s nothing to just look at the quality rank. The key is that you can be an assistant to the Taixue teaching staff. If you are a doctorate in the Taixue teaching staff, you will be an assistant to the teaching staff. Anyway, you are all top students.

There are other nouns "armillary sphere", "Chenxing". The armillary sphere is the equipment used to observe astrological signs in this era. Chenxing refers to Mercury among gold, wood, water, fire and earth. In other words, Zheng Tong and Dr. Liu are arguing about issues in the astronomy field.

Astronomy? I knew that the earth was round and circled around the sun. Then there were nine planets in the solar system, and the twelve zodiac signs, which were almost the same!

Seeing that it was a field that he didn't understand at all, Yuwen Wen was afraid, and thanks to the question that he had not attracted attention, he decided to leave, but just as he was about to turn around, Zheng Tong discovered: "Eunuch? He is a shameless job!"

"Assistant Liu, this is the Duke of Xiyang County, and the governor of Bazhou, Yuwen, is named Wen."

Yuwen Wen complained when he heard this, and the middle-aged man came back to his senses when he saw this and bowed to his salute: "It turned out to be the envoy of Yuwen. In the lower capital, Liu Zhuo, whose courtesy name is Shiyuan, he was just out of rude."

"Envoy, Liu Shiyuan is an assistant teacher in the Imperial College. Today, I am here to discuss with the Imperial College."

"Ah...haha, what are you discussing? It's so intense? I heard it next door." Yu Wen Wen smiled, but he felt extremely helpless.

"I am discussing the matter of Chenxing with Master Zheng Bo," Liu Zhuo replied, "I have heard from Master Zheng Bo mention it, saying that Master Yuwen is quite knowledgeable about astronomy and arithmetic, and I wonder what opinions are there on this?"

'Which ear did you hear me say that I was proficient in astronomy?' Yuwen Wen roared at Zheng Tong in his heart, like countless grass and mud horses galloping by. He didn't know what was going on.

Yuwen Wen was about to admit defeat, but then he found that Zheng Tong was making gestures to him, and then he was excited.

"I am ashamed of being aware of it. I learned Western astronomy, which is slightly different from Central Plains astronomy... But he has quite some experience in arithmetic." He had a modest expression, without any intention of blushing.

"Western? Could it be Persia or Fuji?" Liu Zhuo was quite interested when he heard this. "I wonder how the calendars used by these two countries are different from the Central Plains?"

"Is there a parallax of sun and moon? How many years can I calculate the difference between the ages?" he asked incessantly, "I can calculate the difference between the ages of about seventy-five years and November that Zu Wenyuan calculated.

"I believe that the twenty-four solar terms should have 'stabilizing sun'..."

"Does Western countries measure sun shadows? I believe that the ancient book says that 'the shadows of thousands of miles are one inch different' is actually a fallacy..."

Yuwen Wen listened to the other party's question as if he was listening to a book of heaven, what were the "sun and moon parallax", "period", and "date of the sun". He couldn't understand at all. Seeing Liu Zhuo's expectant expression, he felt bitter in his mouth.

If a poor student meets a top student, he will have to be even more embarrassed!

Yuwen Wen came to Yecheng this time and arranged a task for Zheng Tong who was accompanying him, that is, to recruit talents as much as possible, especially academic masters who are proficient in classics, history, and collections. He wanted to set up a provincial school in Bazhou, and the academic masters urgently needed to take charge.

As a result, Liu Zhuo seemed to be very proficient in calendars. Those who are proficient in calendars these days must be proficient in astronomy. He also has first-class arithmetic skills and is also an assistant teacher in the Imperial Academy. I think he has a good knowledge of classics, history, and collections.

The key is that the name of "Liu Zhuo" is a bit familiar, but Yuwen Wen was anxious to remember whether this person was left in history.

Zheng Tong made a gesture just now, meaning that this talent that was "attracted" was needed to strive for Yuwen Wen, so he had to make it right now. After a moment, he had made up his mind and asked with a smile: "Assistant Liu asked, it is not the director of the official position. I wonder if Assistant Liu had ever heard of astrology?"

"Astrology? I'll say frankly that star sighting at night is the basis of astronomicality. Is it unique to Western astronomy?"

"Yes, the so-called star-watching is nothing more than using your eyes to observe stars, while Western astronomy uses an astronomical mirror." Yu Wen Wen said, and before the other party could react, he continued to ask: "Does Assistant Liu know about the Qianli Mile Mile Mile Mile?"

"I have heard recently that the things that the envoy of Yuwen presented to His Majesty are in it, and there is a thousand-mile mirror?"

"What Master Liu heard about is true. The Thousand Mile Mile Mile Mile Mile allows people to see scenery several miles away. It can be called a military weapon. However, compared with the astronomical mirror, it is like the light of fireflies and the bright moon competing for light."

"This...can the astronomical mirror see thousands of miles away?"

"Haha, Assistant Liu is good at astronomy. Do you know how Saturn looks?"

"Gold, wood, water, fire, earth and other stars are all shining with stars. How can you tell what you look like?"

"But with the astronomical mirror, we can see that Saturn has a halo, surrounding it like a circle!"

Liu Zhuo was stunned when he heard this. Before he could come back to his senses, he heard Yuwen Wen continue: "July ears have big red spots and the moon, and it is full of circular pits."

"To observe the sun with an astronomical mirror, in order to prevent sunlight from burning eyes, you must use ink glass to block it. This shows that the sun is actually round and there are black spots on it."

"The sky is full of stars, but in the astronomical mirror, it looks different. In addition to the five elements of gold, wood, fire, water and earth, there are several stars surrounding the sun and surrounding circles, but they are not distinguishable by human eyes."

"Encourt, Euncourt! Where is that astronomical mirror? Can you find out next?" Liu Zhuo asked anxiously. If it weren't for the etiquette, he would have really grasped Yu Wen Wen's shoulder and shook it.

"I spent a lot of money to create an astronomical mirror. Its body is as thick as a bowl, less than five feet long, and it is very inconvenient to carry. It is still on the observatory platform of Xiyang City, Bazhou Prefecture."

"Bazhou? Bazhou..." Liu Zhuo lowered his head and pondered with a tangled expression. Zheng Tong saw this and said, "Assistant Liu, the envoy has a thousand-mile mirror on his hand. Although it is not as good as an astronomical mirror, it is quite interesting to watch the moon."

Seeing Liu Zhuo's expression of Ai Ai, Yuwen Wen waved his hand in a generous manner: "If Assistant Liu wants to see it, then just watch it casually, but this thing is quite precious and must be limited to use it only in the residence."

"Assistant Liu is not going to stay in the residence tonight. Let's use this Mileage Mile to watch the star sign at night." Zheng Tong struck while the iron was hot.

"This...this is just annoying..." Liu Zhuo had forgotten to refuse and felt embarrassed. Seeing this, Yuwen Wen decided to add another fire. He cheered himself up and said:

"Is Assistant Professor Liu proficient in counting?"

“A little research.”

"Then you must know the number of Pythagoreans?"

“This is natural.”

"I am aware of Western arithmetics and know that there is one science called geometry, and there is another science called trigonometry, which is studied called trigonometry."

"The triangle contains the number?" Liu Zhuo felt enlightened when he heard this, "Is it similar to the number of Pythagoreans?"

"Of course, it's just that there is development. Sima Yang Ji of Bazhou got Yiren to teach Western arithmetic secrets. This secret recordes the mystery of trigonometric functions in trigonometry, and I have also learned a little..."

"Encourt! Can this trigonometry be revealed one or two?"

"It's better to talk inside?"

"Please, please..."
