"Land is the foundation, and the coast is the pasture. Your master once said that people need to eat meat, and the two most nutritious and easily available meats in the world are pork and seafood.

Even though beef and mutton are a bit too dry, it’s okay to eat less or eat them when the weather is cold.”

Wang Zhen paused for a moment and continued, "People are driven by interests. Only by making all kinds of food in the sea delicious can we attract people's attention to the sea.

We don't need too much. As long as they can help us find out the water patterns along the coast, that would be a big help. As for the open sea, we have to figure it out ourselves."

"The distant sea?" Fang Zhe looked at his husband blankly and asked blankly, "The sea is so vast that we will get lost if we go a little further. How can we explore the distant sea?"

"hey-hey."

Wang Zhen drank another cup of sake and said with a tipsy smile: "Your master uncle is the best among us in politics and has gone to the desert. Your second master uncle is good at big data analysis and is very good at capturing details. In his eyes, there are basically no secrets. He has gone to the Western Regions.

With it, we can know our exact position in the sea and won't get lost. As long as we have a direction in the sea, our safety is guaranteed."

Fang Zhao fiddled with it for a while and saw Zhang Gou looking eagerly on the side, so he handed the instrument to him. Zhang Gou put his eyes close to the telescope and began to look around. It was his first time to come into contact with such a magical thing, which made Zhang Gou feel very novel.

Wang Zhen shook his head cheerfully, "Don't mind it. After all, you are still young and lost your father at an early age. It's good enough that you can learn addition, subtraction, multiplication and division by yourself. The reason why the advanced chapter is called advanced chapter is that it is not so easy to learn.

Wang Zhen smiled indifferently, waved to the disciple who saluted him, and said: "The teacher taught us that life is a matter of fate, and we should accept it as it comes, without forcing it or shirking it.

Wang Zhen pondered for a moment and asked, "How are you doing with the advanced chapters of arithmetic?"

Not to mention you, a little boy, in order to learn advanced chapters of arithmetic, there are at least a hundred Confucian scholars who come to Yuzhou every day with their gifts to seek advice.

Ever since the Yuzhou group fled to the borderland, the names of Wang Zhen and his companions naturally began to spread throughout the world, and their personalities, knowledge, etc. also spread at the same time.

Fang Numa picked up the sextant, put his eyes close to the small telescope and looked at it, exclaiming: "This telescope is so clear. Although the telescopes on the market can also see farther, they are far inferior to this one."

It just so happens that I have come to Lingnan. If your second master came to Lingnan, even if you cried to death in front of him, you probably wouldn't be able to join my Yuzhou branch. It's a special favor for him to let you enter the academy as a registered student."

However, if you want to use the sextant well, it is not enough even if you have mastered the advanced chapters on arithmetic. You have to wait until you have finished learning the popular advanced chapters and then practiced my personal secret book for two years before you can say that you can use the sextant well.

Your little aunt is very clever and can learn anything easily. She went to the Northeast, one of the four great borderlands. Lingnan is the richest and produces the most. But do you know why your master, who is mediocre in all aspects, was assigned by your master to the richest south? "

Fang Numa cooperated very well and asked, "Why is that?"

Wang Zhen looked very proud when he said this. All of the disciples taught by the master were extremely talented and hardworking, otherwise they would not be able to be by the master's side. It is not easy to stand out among those guys.

"Look, it's because of this treasure, called the Sextant, which your master developed after observing the stars for a year when he had some free time, and then worked with the people in the gym for three months.

Fang Zan blushed and said, "I can only do addition, subtraction, multiplication and division by counting beans. As for the advanced chapters, I only figured out the basics by myself because no one taught me."

"Of course. Civilian products are just for making some money to cover research and development costs. How can they be compared with military products? Besides, the telescope here is much more advanced than the military ones."

The two little guys shook their heads. Wang Zhen got up and carried out a small box from the inner room. He opened it with his key and took out a fan-shaped tool.

Fang Zhao had naturally heard of his second uncle-master. Judging from the rumors, if his second uncle-master really came to Lingnan, there would be no way he would be accepted as his disciple. Thinking of this, Fang Zhao couldn't help but feel somewhat fortunate.

As for whether you can calculate accurately at that time, it depends on your personal understanding. Your second uncle's arithmetic skills are amazing to even your master, but the error in calculating the sextant is always greater than mine."

"Thank you for your mercy, sir. I will never forget it."

Although my calculation time is slightly longer than his, the accuracy is higher than his. When using a sextant, the calculation time is not important, as long as the calculation is accurate. This is the real reason why I came to Lingnan.

"Hehe." Wang Zhen smiled complacently, "Because the sextant not only requires calculations, but also requires knowledge of astronomy and geography. When the sextant was first made, it was your master's observation of the sky. Although I am not as good as your second uncle in arithmetic, I am a little better than him in astronomy and geography.

Fang Zhao thought for a moment and asked Wang Zhen, "Sir, how do you use this treasure?"

Looking at the exquisite instrument in the box, Fang Zhao asked greedily, "Sir, can I try it out?"

No matter whether it is a person or a thing, no matter whether it is good or bad, just accept it when you encounter it and deal with it according to your own wishes. As for the result, it is not that important.

You and I, master and disciple, were originally thousands of miles apart. You were born into a noble family, and I came from a small farming family. No matter how you look at it, the possibility of us meeting was slim. But chance made us master and disciple. I will teach you well, and you just need to study hard.

As for the future, let's talk about it later. People's minds are fickle, and we in Yuzhou never believe in any oaths. It is more efficient to do things according to the current situation and the heart."

Fang Zhao was stunned for a moment, then smiled and said, "I am very lucky to be able to join the Yuzhou sect in this life."

Wang Zhen smiled, looked towards the northeast, and finally sighed with a hint of bitterness: "Sir, although your mission did not make me go against my will, it made me very embarrassed."
