The Nanyang Ye family has a long history, and the family belongs to the descendants of Ye Wang, the ancestor of the Jiangnan Ye family. Ye Wang was originally from Ye County, Nanyang County (now Henan), once served as the Taishou of Yanmen, was a doctor of Guanglu at the end of the Han Dynasty, crossed the river from Qingzhou in the second year of Jian'an, and lived in Jurong in Danyang (modern Jurong, Jiangsu), the ancestor of Ye's southward migration. The fourth passed to Ye Ju, Ren Qiantang (now Hangzhou, Zhejiang) order, loved the people like a son, and was known as "Father Ye". Ye Ju settled in Qiantang with the help of the people and became a local nobleman. After Ye Ju died, he was buried on the right side of Maoshan in Songyang, Baizhou, and was called the ancestor of the Ye family in Kuozhou or Maoshan.

Ye Ju had four sons, and the second son, Ye Jianshi, was promoted to the general of Zhichong and stayed in Songyang. Ye Jian's descendants live on the right side of Mao Mountain from then on, because of the construction of the ancestral hall far away, people are called Mao Feng Guang (Kuang) far Ye Shi. Ye Fashan, a famous Taoist priest in the Tang Dynasty, is the nineteenth grandson of Ye Ju!

Therefore, it is not impossible to say that Ye Fashan is from the Ye family in Kuozhou!

"Does the Dao Elder know my uncle?"

After Ye Fashan heard Li Chunfeng's muttering, he was puzzled.

His uncle Ye Jingneng is now in his seventies, and Li Chunfeng in front of him, no matter how you look at it, he is at most twenty or thirty years old, and it stands to reason that he should have no intersection with his uncle!

"When Uncle Ling was still the prince of the country, Poor Dao had a relationship with him, but Uncle Ling may not remember it clearly!"

Li Chunfeng smiled slightly, but he was reluctant to elaborate.

Ye Fashan was not reluctant, the two Taoist priests who had left a strong mark in the history of the Tang Dynasty exchanged Taoism for half an hour, and seeing that it was about to be noon, Li Zexuan invited the two to the canteen of Yanhuang Academy.

After seeing the clear and magnificent canteen, Li Chunfeng couldn't help but sigh at the pride of Yanhuang Academy in his heart, Ye Fashan was not much surprised, because this kid had just come here to visit.

At this time, the students have not yet finished school, and there are basically no students in the academy who dare to skip class and eat early, so the cafeteria is not crowded at all, and only a few teachers who have not had classes in the morning eat here in advance. After they saw Li Zexuan, they hurriedly greeted one after another, Li Zexuan smiled and didn't say anything.

The three of them ordered a few plates of side dishes, a pot of gentle countrymen, found a seat by the window, sat down, and began to drink.

"Daochang Li, my cousin plans to go out to seek Taoism next year, you are his elder in this regard, you have to teach him some experience!"

Taking a sip of wine, and then taking a sip of Feihuang Tengda, Li Zexuan looked at Li Chunfeng and got down to business.

He has only known Ye Fashan for more than a day, and it stands to reason that he is not familiar enough to worry about him, but he just can't help but worry about it, maybe he has traveled from modern times, and he knows that Ye Fashan is destined to be extraordinary, so he can't help but care, right?

"Huh! Master Hou is worried that Ling Di is young and may be in danger when he goes out, right? ”

Li Chunfeng took a sip of wine, his eyes seemed to be able to perceive the world, he glanced at Li Zexuan, and said with a smile: "When Poor Dao was nine years old, he traveled away from home and went to Jingyun Temple in Nantuo Mountain to learn art, and he didn't meet any villains along the way. Moreover, the younger brother's forehead is high, his eyebrows are upturned, and the heavenly court is full, which is the appearance of great wealth and nobility, and he will not encounter unexpected disasters in a short period of time! ”

Only then did Li Zexuan know that the Taoist priest in front of him was even more fierce, and he began to travel the world at the age of nine, he couldn't help but secretly say, are all these ancient people so demonic?

"Thank you Dao Chang Ji Yan~!"

Li Zexuan's heart was a little relieved, and at the same time, he was a little enlightened, Li Chunfeng could see Ye Fashan's side clearly, so how could Ye Guozhong not see it? No wonder the old man is not in a hurry at all, it is probably all under his control!

"Hehe, if you want to say that Xie is also poor, you should thank Hou Ye, I'm afraid that the dog will cause trouble to Hou Ye in this Yanhuang Academy!"

Li Chunfeng said politely.

Li Zexuan shook his head and said: "The Taoist chief is laughing, Ling Lang's grades in the academy have always been among the best, why make trouble, the academy has to thank the Taoist for his good tutoring!" ”

Cultivators are also human beings, and when they meet others praising their children, Li Chunfeng can't help but draw a trace of arc at the corner of his mouth at this moment, he picked up his wine glass and said with a smile: "Haha!" This thank you is so boring, a cup of poor Taoism to the marquis, you should be grateful for today's hospitality~! ”

Li Zexuan nodded and took a drink with a smile.

At this time, Li Chunfeng suddenly said: "Master Hou, the channel has used a telescope to discover a star very close to us in the past few days, although it is farther away than the moon, but it is much closer than the stars in the sky at night. It's just that what makes Poor Dao feel strange is that this star can only be observed in the early morning, and at night, it can't be found at all! And around this star, there is actually a circle of light, which looks very beautiful, and the poor road has searched through the astrological charts left by the ancestors, and has not been able to find a record of this star, which is really strange! ”

The astrological chart is not the patent of modern people, the ancient Chinese began to observe celestial phenomena very early, and achieved many achievements that modern Chinese are proud of, inventing astronomical tools such as the armillary heaven and earth seven political instruments, heaven and earth instruments. In the Sui and Tang dynasties, people combined astronomy with numerology, and the theory of astrology came into being, which was based on the idea of "the unity of heaven and man", and inferred the good and bad luck of people with the changes of the stars. By observing the changes in the sky and the stars, people can speculate about the good fortune and misfortune in the world, and the three walls and four elephants, the twenty-eight constellations, and the seven politics and four surpluses are the basis for the inference of the astrological destiny.

After Li Chunfeng said that, Ye Fashan's eyes widened on the side, he never expected that the cylinder with a bracket he saw in the atrium of Guanghua Building before was actually used to observe the stars, and listening to Li Chunfeng's meaning, he was actually observing the stars in half a day, why did this sound so mysterious?

Li Zexuan was secretly surprised, because listening to Li Chunfeng's description, it was very likely that he had inadvertently discovered Saturn!

Saturn can be regarded as one of the more peculiar planets in the solar system, in the telescope, its appearance looks like a straw hat, and the presence of the halo makes Saturn the most beautiful of the stars, which makes the viewer amazed. At first, it was thought that only Saturn had rings in the solar system, but it was not until the late 70s and late 80s of the 20th century that the discovery of the rings of Uranus, Jupiter, and Neptune changed this view.

The astronomical telescope made by Mo Lingwei has a small aperture and magnification, and the imaging effect is not good, so it is ruled out that the stars seen by Li Chunfeng are Uranus, Neptune, and Jupiter.

"Congratulations to the Dao Chief, you have discovered a new star, in time, maybe the Dao Chief can make the existing astrological chart more perfect, and then it will be famous in history!"

Li Zexuan smiled with a smile.

He didn't tell him about the nine planets in the solar system, oh, it should be the eight planets, some things are too easy to get, people won't cherish them, sometimes being a quiet "prophet", let the world discover what they already know, this feeling is also very good.

Li Chunfeng hurriedly waved his hand and said: "This is not the credit of Poor Dao, if it were not for the help of the astronomical telescope of Yanhuang Academy, Poor Dao would not have made this discovery, besides, Poor Dao still has one thing to solve, that is, why can't this planet be observed at night?" And why is there a ring of light around the star? ”

At this time, Li Chunfeng, as soon as he talked about his new discoveries, he forgot that "he didn't say anything when he ate and didn't say anything when he slept", although Li Zexuan had never shown his talent in astronomy, but his intuition told him that Li Zexuan must know.

Li Zexuan thought for a while and prompted: "Dao Chief, you can think about it, why can you only see the moon at night, but you can't see the moon during the day?" The star that the Dao Chang observed that can only be seen during the day may have a similar principle to the moon! ”

The angular distance between Saturn and the Sun is smaller than that of Mercury, and 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, you can clearly see Saturn's rings with ordinary telescopes.

"As for the aura around that star, as long as the Dao Master understands why the moon is shining, he will be able to figure out what that aura is!"

Saturn's rings are made up of debris from comets and asteroids colliding with larger Enceladus. Auras can contain large amounts of water, and they are composed of ice cubes and snowballs ranging from a few centimeters to several meters in diameter. These substances are reflected by sunlight to form bands of light that are seen by the human eye.

Li Chunfeng was thoughtful when he heard this, and after a while, he arched his hand and said: "Master Hou is really knowledgeable and knowledgeable, and he has been taught!" ”

"Don't dare, don't dare! When the telescope is more perfect in the future, I believe that the Taoist can discover more stars, and then celebrate the Taoist chief~! ”

Now Mo Lingwei and Yan Shaoning are rushing to produce a batch of military telescopes for the military, so the improvement of astronomical telescopes has been put down for the time being. However, Li Zexuan believes that as the technology of making telescopes in the workshop becomes more and more mature, the telescopes produced will definitely become more and more advanced, and maybe Li Chunfeng can use the telescope to find out all the major planets in the solar system!

In that case, Li Chunfeng may take advantage of the situation 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 heliocentric theory in the West was first proposed, many people suffered because of it.

Ye Fashan was stunned when he listened to the conversation between the two of them, before this, he was proud of his knowledge, of course, he had also heard a lot of things about Li Zexuan, and felt that this cousin could be in a high position with his own efforts, and he still had the ability, but he didn't expect that his knowledge was so profound, he had never heard of many things, but Li Zexuan could talk to Li Chunfeng eloquently, this is the gap!

At this moment, Ye Fashan is even more determined to go out to seek Taoism, if he refuses to step out of the house, he can only be a frog at the bottom of the well for the rest of his life!

……………………………

After a lunch meal lasted for nearly half an hour, it was close to the end of the students' school day, and the three of them left.

After Li Zexuan had lunch, he went back to the Yunshan Courtyard to rest for a while, while Ye Fashan was meditating and resting in the backyard.

In the afternoon, Li Zexuan took Ye Fashan, who "went out to collect wind and harvested a lot", to prepare to return to Chang'an. Originally, he also planned to take this cousin to the west of Yunshan to see if the farmers would encounter wild beasts when collecting medicine, but Ye Fashan couldn't bear to see the beasts being killed, so he gave up.

When he came, he came over, and when he went back, Li Zexuan said that he didn't want to continue walking, he felt that it was a waste of time, so he "borrowed" two horses from the guards of the academy, one for one and one for ride, and rushed to Chang'an.

"Da Da Da Da~!"

All the horses of Li Zexuan's personal guard had horseshoes, and when they walked on the hard and flat cement road, the sound of the horses' hooves hitting the ground was particularly clear.

Not only do people like to walk on the flat cement road, but the horses also like it, and once they get on the cement road, they can clearly feel that the speed of the war horse under the crotch is faster.

At this speed, it didn't take long for them to finish the cement road, and after another quarter of an hour, they finally got off the trail and walked onto the official road, but who knew that there was a large group of officers and soldiers coming in front of them, and there were about thousands of people in total.

"Huh~!"

When Li Zexuan saw the person who was the leader, he hurriedly controlled the war horse to stop, and jumped off the war horse to meet him.

"Lord Wang, are you going to lead the troops south~?"

Li Zexuan asked.

That's right, the person who came was Li Xiaogong. He was also followed by dozens of officials.

Li Xiaogong saw that it was Li Zexuan, so he asked the army to move forward slowly, and he himself would catch up with him after a while, and then he replied to Li Zexuan: "Yes, now that the prototype of the city division has been built, and the officials of the key departments have also been put in place, Your Majesty is in a hurry, so the king can only take them to Guangdong in such a hurry~!" ”

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

"Then the prince is careful all the way!"

Li Zexuan hugged his fists.

"Yo~! ...... is this little guy? ”

Li Xiaogong saw Ye Fashan and asked curiously.

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

"Cousin?"

Li Xiaogong pondered for a moment, and suddenly realized: "Oh! Are people from your mother's family willing to come to your mother? Hehe, the king also knew a thing or two about your mother back then, but I didn't expect that the Ye family would still be soft in the end, haha! ”

Li Zexuan was speechless, listening to what Li Xiaogong meant, he had long known about the affairs of the Li and Ye families, but this guy was really tight-lipped and didn't know how to say it in advance, he was really cunning!

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

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