Otaku Engineer in Great Tang Dynasty

The Ye family in Nanyang has a long history. The family belongs to the descendants of Ye Wang, the ancestor of the Ye family in Jiangnan. Ye Wang was originally from Ye County of Nanyang County (now part of Henan). He was once the prefect of Yanmen. At the end of Han Dynasty, he was the doctor of Guanglu. In the second year of Jian'an, he crossed the river from Qingzhou to the south. He lived in Danyang Jurong (modern Jiangsu Jurong) and moved south for the Ye family. Ancestor. It was passed down to Ye Ju, and he was appointed as the order of Qiantang (now Hangzhou, Zhejiang). He loved the people like his son and was called "Father Ye". Ye Ju settled in Qiantang with the people's retention and became a prominent local family. After Ye Ju's death, he was buried at the right of Maoshan in Songyang, Zhuzhou, and is known as the ancestor of the Ye family in Kuozhou or Maoshan.

Ye Ju has four sons. The second son Ye Jianshi was promoted to general Zhechong and stayed in Songyang. From then on, Ye Jian’s descendants lived on the right of Maoshan Mountain. Because of the construction of the temple, they were known as Maofengguang (Kuang) Yuan Ye family. The famous Taoist Ye Fashan in the Tang Dynasty was the 19th grandson of Ye Ju!

So it's not unreasonable that Ye Fashan comes from the Ye clan in Kuozhou!

"Do you know my uncle?"

Ye Fashan was puzzled after hearing Li Chunfeng's mutter.

His uncle Ye Jingneng is now in his seventies, and Li Chunfeng in front of him, no matter how old he looks, is at most twenty or thirty years old, logically speaking, there should be no intersection with his uncle!

"When Uncle Ling was still the Imperial College to sacrifice wine, Pindao once had a relationship with him, but Uncle Ling might not remember it!"

Li Chunfeng smiled slightly, but did not want to elaborate.

Ye Fashan was not reluctant. Two Taoist priests who have left a lot of color in the history of the Tang Dynasty have exchanged the Taoism for half an hour. Seeing that it is almost noon, Li Zexuan invited the two to go to Yanhuang Academy. canteen.

After seeing the magnificent dining hall with a clear window, Li Chunfeng couldn't help but sigh in the bottom of his heart for the pride of Yanhuang Academy. Ye Fashan was not surprised because this kid had just visited here.

At this time, the students have not finished school, and there are almost no students in the college who dare to skip classes to eat in advance, so the cafeteria is not crowded at all, only a few teachers who have no class in the morning eat here in advance. After they saw Li Zexuan, they greeted Li Zexuan with a smile, and said nothing.

The three of them ordered a few dishes, a pot of Gentle Township, found a seat by the window, and began to drink.

"Dao Master Li, my cousin plans to go out and seek the Taoism next year. In this regard, you are his elder, and you will have a good life to teach him some experience!"

After drinking a sip of wine and taking another sip of Feihuang Tengda, Li Zexuan looked at Li Chunfeng and started talking about business.

He has only met Ye Fashan for more than a day. It is reasonable to say that he has not been acquainted with him to the point of worrying about him, but he just can’t help worrying about it. Perhaps he, who has traveled from modern times, knows that Ye Fashan is destined to be extraordinary. To care?

"Haha! Lord Hou, this is worrying that Lingdi is young and might be in danger when he goes out?"

Li Chunfeng took a sip of wine, with a pair of eyes that seemed to be able to insight into world affairs. He glanced at Li Zexuan and said with a smile: "When Poverty Road was nine years old, I traveled far away from home and went to Nantuo Mountain to watch and study art. I haven't encountered any evil people on the road. Moreover, my brother has a high forehead, raised eyebrows, and a full sky. This is the appearance of great wealth and nobleness, and there will be no accidents in a short time!"

Only then did Li Zexuan know that the Taoist priest in front of him was more fierce. He began to wander the world at the age of nine. He couldn't help but secretly said, are these ancient people such evildoers?

"Thank you for your good words~!"

Li Zexuan felt a little peaceful, and at the same time he felt a little clear. Li Chunfeng could see Ye Fashan's face clearly, how could Ye Guozhong not see it? No wonder the old man is not in a hurry, he is probably under his control!

"Hehe, if you want to say that Xie is also a poor way to thank Master Hou, I am afraid that the dog is causing trouble to Master Hou in this Yanhuang Academy!"

Li Chunfeng said politely.

Li Zexuan shook his head and said, "The Daoist is joking, and Linglang has always been among the best in the academy, so why bother to say that the academy should thank the Daoist for his excellent tutoring!"

A cultivator is also a human being. Even if Li Chunfeng's heart is still like water, even if he meets others praise his child, the corner of his mouth can't help but draw a curve at the moment. He picked up the wine glass and smiled: "Haha! It's also easy to be thankful It’s boring, I’m thankful for your hospitality today~!"

Li Zexuan nodded and had a drink with a smile.

At this moment, Li Chunfeng suddenly said: "Honor, the channel has discovered a star very close to us with a telescope these days. Although it is farther than the moon, it is much closer than the stars in the sky at night. It’s just that Pindao finds it strange that this star can only be observed in the early morning, and at night, it can’t be found at all! Moreover, there is actually a circle of light around this star, which looks absolutely beautiful and poor. Dao rummaged through the astrological charts left by the ancestors, but couldn't find the record of this star, which is really weird!"

The astrological chart is not a patent of modern people. The ancient Chinese began to observe the celestial phenomenon very early, and achieved many achievements that modern Chinese people are proud of. They invented astronomical tools such as the astronomical instrument, such as the celestial sphere and the seven political instruments, and the heaven and earth instruments. In the Sui and Tang dynasties, people combined astronomy and numerology, and the theory of astronomy came into being. It was based on the idea of ​​"the unity of nature and man" and used the changes of stars to infer the good and bad of personnel. By observing the changes in the sky astrology, people can infer the good fortune and bad fortune in the world. Three elements, four elements, twenty-eight stars, seven political and four constellations, etc. are all the basis for the inference of star fate.

After Li Chunfeng finished speaking, Ye Fashan widened his eyes. He never expected that the cylinder with brackets that he saw in the atrium of Guanghua Building was actually used to observe the astrology, and listening to Li Chunfeng's meaning, it was actually Observing the astrology for a long time, why does this sound so mysterious?

Li Zexuan was surprised, because listening to Li Chunfeng's description, he might have discovered Saturn accidentally!

Saturn can be regarded as one of the more peculiar planets in the solar system. From the telescope, it looks like a straw hat. The presence of the halo makes Saturn the most beautiful among the stars, which amazes viewers. At first, people thought that only Saturn has a halo in the solar system, but it was not until the late 1970s to the late 1980s that the successive discoveries of Uranus, Jupiter, and Neptune changed this view.

The astronomical telescope made by Mo Lingwei did not have a large aperture and magnification, and the imaging effect was not good. Therefore, it was ruled out that the stars Li Chunfeng saw were Uranus, Neptune, and Jupiter. Compared with these stars, Saturn's halo It is more obvious and easier to be found. If you are lucky, you can see Saturn's halo with the naked eye even without a telescope.

"Congratulations, you have discovered a new star. In time, maybe Dao Chang can make the existing astrological map more perfect, and then you can leave a name in history!"

Li Zexuan folded his hands and smiled.

He did not mention the nine planets in the solar system he knew, oh, it should be the eight planets. Some things are too easy to get, and people don’t cherish them. Sometimes, when a quiet "prophet", let the world It’s also a good feeling to discover what you already know.

Li Chunfeng hurriedly waved his hand and said: "This is not the credit of Pang Dao. Without the help of the astronomical telescope of Yanhuang Academy, Pang Dao would not have discovered this. Besides, Pang Dao still has one thing left unsolved, that is why this planet is at night. Can't observe? And why is there a halo around the star?"

At this time, Li Chunfeng, when he talked about his new discoveries, he forgot to "don't eat and sleep." Although Li Zexuan had never shown his talent in astronomy, his instinct told him that Li Zexuan must know .

Li Zexuan thought for a while, and prompted: "The Chief Dao can think about why the moon can only be seen at night, but not during the day? The principle of the star that the Chief Dao observed can only be seen during the day. Maybe similar to the moon!"

The angular distance between Saturn and the sun is smaller than that of Mercury. It basically rises and sets with the sun. So when the sun rises in the morning, as long as the weather is clear and the air visibility is high enough, it can be clearly seen with ordinary telescopes. Seeing the halo of Saturn, Galileo used a self-made telescope to discover Saturn in this way!

"As for the halo around that star, the Taoist leader can figure out what the halo is if he understands why the moon shines!"

Saturn's halo is made up of debris from the collision of comets and asteroids with larger Titans. Auras may contain a lot of water, and they are composed of ice cubes and snowballs ranging from a few centimeters to several meters in diameter. Under the sunlight, these substances reflect and form the light bands that people see.

Li Chunfeng was thoughtful when he heard the words. After a long while, he handed his hands and said: "Master Hou is really talented and learned, and I have been taught by the poor!"

"Don't dare! When the telescope becomes more perfect in the future, I believe Dao Master will be able to discover more stars, and then I will celebrate the Dao Chang again~!"

Now Mo Lingwei and Yan Shaoning are rushing to build a batch of military telescopes for the military, so the improvements to the astronomical telescopes are temporarily put down. But Li Zexuan believes that as the workshop's technology for making telescopes becomes more and more mature, the telescopes produced will definitely become more and more advanced. At that time, maybe Li Chunfeng can use the telescope to find all the major planets in the solar system!

In that case, Li Chunfeng might take advantage of the trend to put forward the heliocentric theory, but I just don't know if he will be regarded as an outlier because of this. After all, when the western heliocentric theory was just proposed, many people suffered because of this.

Ye Fashan was stunned to listen to their conversation. Before that, he was proud of his knowledge. Of course, he had heard a lot about Li Zexuan and felt that this cousin could rely on his own efforts. In a high position, he still has the ability, but he did not expect that his knowledge is so profound. He has never heard of many things, but Li Zexuan can talk to Li Chunfeng. This is the gap!

At this moment, Ye Fashan became more determined to go out to seek the way. If he refused to step out of the house, he would have to be a frog in the well for the rest of his life!

……………………………

Nearly half an hour after a lunch, the three came out when the students were over.

After lunch, Li Zexuan went back to the Yunshan courtyard to rest for a while, while Ye Fashan meditated in the backyard.

In the afternoon, Li Zexuan brought Ye Fashan, who was "out to collect the wind and harvest", to prepare to return to Chang'an. Originally, he planned to take this cousin to the west of Yunshan to see if the villagers would encounter wild beasts when collecting medicine, but Ye Fashan couldn't bear to see the beast killed, so he gave up.

When I came, I walked over. When I returned, Li Zexuan said he didn’t want to go any further. He felt that he was a waste of time, so he “borrowed” two horses from the guards of the academy. Rush away.

"DaDaDa~!"

All the horses of Li Zexuan's Guards were ordered with horseshoes. Walking on the hard and flat concrete road, the sound of the horseshoe and the ground was particularly clear.

Not only do people like to walk on flat concrete roads, but horses also like them. Once on the concrete road, you can obviously feel the speed of the horse running under the crotch.

At this speed, they finished walking on the cement road after a short while, and after another half an hour, they finally got off the trail and walked onto the official road, but a large group of officers and soldiers came oncoming. Add up to a few thousand people.

"Call~!"

When Li Zexuan saw that for the head of the person~www.ltnovel.com~, he quickly controlled the horse to stop, and jumped off the horse to meet him.

"Master, are you going to lead soldiers to the south~?"

Li Zexuan asked.

Yes, the person here is Li Xiaogong. There are dozens of officials behind him.

Li Xiaogong saw that Li Zexuan came, so he asked the army to move forward slowly. He later hurried to catch up with Li Zexuan. Then he replied to Li Zexuan, "Yes, now the prototype of Shibosi has been built. The officials are already in place. Your Majesty is in a hurry, so this king can only take them to Guangdong in such a haste~!"

It can be seen that Li Xiaogong himself does not want to go to the south at this time. After all, the New Year will be in more than a month. If Li Xiaogong goes to Guangdong now, it is very likely that the New Year will have to be spent there!

"Then prince be careful all the way!"

Li Zexuan clasped his fist.

"Yo~! This little guy is...?"

Li Xiaogong only then saw Ye Fashan and asked curiously.

Li Zexuan introduced: "Master, this is my cousin Ye Fashan, a member of the Ye family in Nanyang, Chang'an who just arrived yesterday!"

"Cousin?"

Li Xiaogong pondered for a moment, and suddenly realized: "Oh! Your mother's family is willing to come over to find your mother? Haha, the king also knew about your mother's affairs back then, but I didn't expect that Ye family would still be subdued in the end, haha!"

Li Zexuan was speechless. Hearing what Li Xiaogong meant, he had known about the Li and Ye family for a long time, but this guy was really tight-lipped, and he didn't know how to say it in advance. He was really old and cunning!

"Haha, by the way, Xiaoxuan, take a closer look at this king's team, who is your old acquaintance?"

Li Xiaogong suddenly lowered his voice and said mysteriously to Li Zexuan.
