Speaking of astrology, anyone who knows a little about navigation has heard of it, but not everyone is familiar with it.

The so-called stars are naturally related to the stars in the sky. At the beginning, in the Qin and Han dynasties, there were already people who used the position of the stars in the sky to follow the angle of the sea surface to determine the direction.

There is such a sentence in the Western Han Dynasty's "Huainanzi Qi Folk Training": "Those who are confused by boat do not know things, and when they see the fight, they will be enlightened." ”

At that time, the ocean was boundless, and it was impossible to know the direction of east and west, so it could only rely on the rise and fall and transfer of the sun, moon and stars, the purpose of which was to guide the ship forward. This gives rise to the art of star pulling, which also has a rather atmospheric name called "transoceanic star pulling".

But when it came to the former Northern Song Dynasty, it was very different.

Before that, if there is the sun, moon and stars still know the direction, if it is cloudy, it can only be resigned to fate, so the south needle and water compass of the previous dynasty make the navigation orientation less difficult, even if it encounters any obscure day, there is no need to be afraid, so that for a time there are more and more people going to sea, and the distance from home is getting farther and farther.

It's hard to imagine, if there were no things like the South Needle and the Water Compass, how would Zheng Gong and his huge fleet travel back and forth to the South Seas? How do you come and go so much?

It's just that although there are many people who know the art of astrology nowadays, there are only one or two who are really proficient.

Before many students in the workshop set off for Nanjing, most of them knew that there was a treasure in this Zhenhai Shipyard, that is, the master of the cross-ocean star pulling technique that few people in the Manchu Dynasty could beat, and many of them came to him.

It's just that the time is not long, and they haven't yet known that the person who holds the exquisite art is none other than Su Fanyuan, the deputy envoy of Su who is quite nagging in their mouths.

Su Ouruo's words surprised everyone that this astrological technique could only measure the stars in the sky and the vast sea with a single stroke, and a little man who didn't seem to have grown up could study such a suspenseful knowledge.

This is just one of them, what makes everyone even more surprised is that if you dare to find someone to learn from the star pulling technique in the lecture hall of this Zhenhai Shipyard, wouldn't it be a big axe in front of Lu Ban's door?

About everyone present was trapped in these two thoughts, so they were a little silent for a while, but the master who had just spoken was indifferent, with a smile on the corner of his mouth, and he didn't speak again for a while.

Su Ouruo looked at this person and saw that he was holding an ebony satin fan in his hand, which was quite commensurate with the long shirt on his body, and it was a delicate thing.

This person's eyes are like stars, his eyebrows are like paint, and his expression is a bit unconventional, although he is making things difficult for her, he can't see the violent and vicious color at all, on the contrary, Su Ouruo still thinks that this person looks ...... It's very comfortable.

Before she could figure it out, the person in front of her immediately spoke: "Astrology? This is not something easy to learn, little brother understands this? ”

"I know a little bit about it."

"So and so I asked for a word or two. I remember that the Song Dynasty in the previous dynasty had written the book "Pingzhou Can Talk", which contained a few sentences written about this astrology, a certain forgetfulness, I can't remember it for a while today, can the little brother remember? ”

Su Ouruo thought about it, and frowned slightly: "But ...... sentence 'The boat master knows geography, watches the stars at night, watches the sun during the day, and looks at the compass when it is cloudy'?" ”

The person holding the fan nodded slightly: "That's right, I also remembered it." …… Oh, by the way, I would like to ask you again, what kind of star is this astrological technique? ”

"First look for Beidou to set Beichen, and then lead Beichen to practice, if you can't see Beichen, then change to pull the canopy."

"What if there is no more canopy?"

"You can choose the Weaver Girl and the Lantern Bone Pulling Technique."

The smile on the face of the fan boy deepened at this time, and he stared at Su Ouruo's face for a long time.

"This benevolent brother ,...... But what else do you have to ask? Su Ouruo was stared at and felt uncomfortable, so he asked.

Before he could answer, he heard a scolding voice under the porch of the door: "You are arguing and arguing again!" The old man has said it a hundred and eighty times, this is a school, a place to talk about rules, not a place for you to say a word to me in the vegetable market! ”

Su Ouruo was so frightened that his soul was almost gone! Isn't this the dad she's been protecting just now!

It's miserable, I've been thinking about how to maintain his integrity and knowledge, but I forgot for a while that I can't be seen by him, and now she can't escape even if she wants to!
