When Su Dawei walked into the Secret Pavilion, Li Chunfeng had just done his routine every day.

In the middle of the Secret Pavilion, there is an altar.

It is somewhat similar to the Temple of Heaven that later generations worshipped the sky.

The functions of the Secret Pavilion are not only to collect the Yi Ren and suppress the weird things, but also to observe the astronomical phenomena, the Ming calendar, and the geoscience.

Su Dawei led the way through Zhi Jinwu in the secret pavilion and came to the altar. He happened to see Li Chunfeng holding a heavy book in his hand and holding a pen in his right hand, step by step from the high-level temple of heaven in a strange posture.

"Minister's Officer, what are you doing?"

Su Dawei was a little confused.

If Li Chunfeng was doing it, he was holding a scroll and a brush in his hand.

He said he was mapping the celestial phenomena, and his walking posture was so enchanting, it was like hemorrhoids.

Li Chunfeng didn't know what Su Dawei was thinking.

If you know, you may not be able to hit you with a thunder.

He handed the brush and book in his hand to the people around him with a little pride. While cleaning his hands in the copper basin held by the servant, he smiled at Su Dawei: "Why, I haven't seen it before? I just left Yubu."

"Yu Bu? Stepping on the Gang Bu, the method of praying for sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial

Su Dawei asked subconsciously.

He knew that when he watched the Romance of the Three Kingdoms in his previous life, Prime Minister Zhuge finally prayed for his birthday to the Big Dipper, but Wei Yan flew up and kicked the Longevity Lamp.

"It's not about praying for me, it's about measuring the vastness."

"The doctor of the Secret Pavilion, who can understand what he says."

Li Chunfeng laughed.

"I'm measuring stars."

"Broad day..."

"Looking at the sun, even during the day, you can deduce many things according to the different sunlight projection positions."

Li Chunfeng pointed to the high platform behind him: "This is the most suitable place for Chang'an to observe sunlight. Look, there is a stone plate on the altar and a needle in the plate. You can infer the time based on the sun shadow. There are also twelve zodiac stars engraved on the stone plate..."

Li Chunfeng's father Li Bo served as a minor official in the county government during the Sui Dynasty. He was not successful in his ranks and abandoned his official position and became a Taoist priest. He was quite knowledgeable and called himself Huang Guanzi? He wrote "Laozi" and wrote ten volumes of local chronicles, "Fu on Astronomy and Elephant", etc.

Li Chunfeng, who was known as a "child prodigy" since childhood, was influenced by his father. He was well-read and particularly fond of astronomy, geography, Taoism, and Yin and Yang.

In the seventh year of Daye in the Sui Dynasty, Li Chunfeng, who was nine years old, went to Jingyun Temple in Nantuo Mountain and became a disciple of Taoist Zhiyuan.

In the second year of Wude of Emperor Gaozu of Tang Dynasty, Li Chunfeng was recommended by people to become Li Shimin's record room and join the army.

In the first year of Zhenguan, Li Chunfeng, who was 25 years old, wrote a letter and put forward eighteen opinions on the "Wuyin Yuanli" written by the Taoist priest Fu Renjun. Taizong accepted seven of them. He was appointed as the General of Li Chunfeng and joined the Taishi Bureau.

Li Chunfeng is also the first person in the world to rank Feng.

His famous book "Yi Sizhan" is the earliest monograph in the history of world meteorology.

He also made the "Tuibei Tu" with Yuan Tiangang, which was predicted until a thousand years later.

Li Chunfeng? Is he definitely a strange man in the astrological numerology of the Tang Dynasty? He is a great master and a great master among the strange man.

"stop."

Su Dawei reached out to Li Chunfeng, who was very excited and honest, and said, "I'm here today..."

"Do you know that I have annotated "Laozi" and also wrote ten volumes of local chronicles, "Fu on Astronomical Elephant", etc., I am just not idle."

Li Chunfeng said, smiling at Su Dawei: "I'll take you to see my improved new armillary sphere later."

New armillary sphere? That is, copper casting of the ecliptic sphere.

It has existed since ancient times.

After Li Chunfeng improved it, he changed the original two-level armillary sphere to triple.

The outermost is the six-hexa ritual? The middle is the three-chen ritual, and the innermost is the four-you ritual.

This instrument can measure the ecliptic longitude and latitude, equatorial longitude and latitude, and horizon longitude and latitude.

"In the fifteenth year of Zhenguan? When I was writing the Book of Jin, I also wrote the three plots of "Astronomy", "Law Calendar", and "Five Elements"? To summarize the research results of previous generations? It is sad that I am not as good as before. In recent years, except for reviewing and annotating the "Ten Sutras" with Liang Shu, Wang Zhenru and others, I have no other achievements.

I just hope to complete the new calendar this year, but I also forget about my wish."

The "Ten Classics of Calculation" includes "Nine Chapters of Calculation" and "Zhoubian Classics", which still have teaching purposes in later generations.

"Stop! Tai Shi Ling, I really have something important."

When Su Dawei looked at Li Chunfeng today, he only felt that his nose was not the nose, and his eyes were not the eyes.

Showing off, Li Chunfeng is purely showing off on purpose.

No, he deliberately wanted to make a point.

"Don't play with silly, do you know what I'm going to do today?"

Su Dawei grabbed Li Chunfeng's sleeve and kept him who was about to turn around and escape.

"Ami, why do you have to catch this muddy water?"

"Do you think I am willing? Your Majesty asked me to examine Li Yifu and Guo Xingzhen. What can I do?"

"Even if you need to review, you have to bring all your staff and follow the process, right? I'm very embarrassed if you come alone."

Li Chunfeng stared into Su Dawei's eyes: "What are you thinking about? I know, but I don't want to go into it."

After saying that, he shook his hand gently, and a soft aura came out of his sleeve.

The sleeves suddenly became slippery and took off from Su Dawei's hand.

"You leave now, I can pretend that you haven't come."

"It's too late. You can think I haven't come, but today I don't dare to think I haven't come."

Su Dawei stared at Li Chunfeng's eyes: "Believe it or not, I will come to you, Your Majesty already knows it."

"You cheat me, forget it."

Li Chunfeng was so angry that his beard was about to rise up, and he shook his sleeves: "Stop, let's do whatever you want. Remember, I haven't come to the Secret Pavilion due to illness today, and you have never seen me."

Seeing Su Dawei nodding, he added: "Also, I have never mentioned anything to you, including witchcraft, you have thought of it yourself. I also want to finish the calendar."

After saying that, Li Chunfeng left.

Really left.

This old man ran faster than a rabbit.

Su Dawei could only smile bitterly as he looked at the direction where Li Chunfeng disappeared.

Li Chunfeng, I didn’t expect that you, a guy with thick eyebrows and big eyes, also learned to avoid disaster and protect yourself.

But it's normal to think about it.

If Li Chunfeng does not have the ability to look at the wind direction, where did his idea of ​​measuring the wind power level come from?

Who is the old minister who can live from Wude to the present day to Wude?

It is clear that this case may become the biggest rebellion case of Li Zhichao since Changsun Wuji and Fang Yiai's conspiracy.

Li Chunfeng naturally avoided it and was afraid that he would not be able to do so.

Su Dawei shook his head slightly and said to the person in the secret pavilion standing aside with a dull face: "I want to see Guo Xingzhen."

Since the incident, Guo Xingzhen was subdued by the strangers of the Secret Pavilion and was directly detained in the Secret Pavilion prison.

The Secret Pavilion has the responsibility to suppress the strange world and collect the strange people and balance the movements of various races. In the Secret Pavilion, there are naturally dark prisons.

Of course, Su Dawei’s request is both reasonable and unreasonable.

Li Chunfeng himself doesn't want to get involved.

Su Dawei wants to examine Guo Xingzhen, that is right.

But he did not bring the people from Dali Temple and the Ministry of Justice. It was obvious that it was a bit inconvenient and wanted to ask Guo Xingzhen alone.

This matter can be big or small.

It depends on what Li Zhi thinks.

In short, except for Su Dawei, no one in the court today dares to bet on the emperor's mood.

Bypassing the corridor, passing through the place where the astrological constellations were measured several times, and after several times of ban, Su Dawei finally came to the prison of the current Secret Pavilion.

Thinking about the past few days, it seems that I have had an indissoluble bond with the prison cell.

The prison of Dali Temple before was now the prison of Secret Pavilion.

Maybe I will go to the Ministry of Justice prison in a while.

True, it's hard to describe.

As Yi Ren, who was leading the way, pushed open a stone door, Su Da was intimidated and stepped in.

When he crossed the threshold, he obviously felt a mysterious power sweeping through his body.
