National Luck: Angry Qin Shihuang at the beginning

Dealing with rebellion while gaining great benefits from rebellion is really contradictory, so I simply don't mention his name, it's better to pretend to be foolish and earn money.

Therefore, "Governor Li of the Qin Kingdom Alliance" is quite mysterious to the Daqin people who came to Taibei later.

Although Governor Li is very mysterious, Fang Yizhi, who has stayed in Taibei for less than three months, has heard that Governor Li is easy to meet. As long as there is a legitimate reason, as long as he is near you, most likely to ask for a meeting All can be seen.

"Yizhi, if you have a chance, with your progress in studying physics, I think the governor will probably take the initiative to find you in a short time."

From the beginning of the first emperor, it has been continuously recorded in the scriptures that emperors wanted to find fairy mountains in the East China Sea in order to live forever.

Although Fang Yizhi, a Confucian scholar, does not believe in the theory of ghosts and gods, "reading thousands of books and traveling thousands of miles" has always been the pursuit of Confucianism.

Fang Yizhi, who was originally planning to study at the Qin Academy of Sciences, heard that there was a fleet going thousands of miles to explore the end of the sea, and this guy couldn't sit still.

Traveling thousands of miles is not only about tempering the will, but also for Confucian scholars to explore the world, the customs of the people's livelihood, and of course, the purpose of making friends with comrades.

But since ancient times, except for the eunuch Sanbao leading the fleet to go to the ocean, he has not found the end of the sea. The feat of seeking the end of the sea is too attractive for the 21-year-old Fang Yizhi.

What's more, he also heard that the leader leading the fleet voyage this time is the dean of the Academy of Sciences. Such a person must be well-educated, and he can increase his knowledge without delaying his studies.

After obtaining the approval to accompany him, Fang Yizhi hurriedly wrote a letter to his family and boarded the ship, because the alliance didn't even require him to prepare the expenses.

Although Fang Yizhi's family is quite wealthy, but someone paid to travel around the world for free, and it is full of sense of accomplishment to say it later.

You must know that in this era, there are only three kinds of people who can travel the world. They are either wealthy, knowledgeable, or famous all over the world.

"Oh, really? Then I have to step up my studies. By the way, brother Zhou Haoyu, I carefully compared the density problem you mentioned two days ago, and it seems to be true! But what effect does the density of this substance have?"

"Ha, I can't remember how to answer you about Yizhi's question and the rest, but it's just right on this boat.

You see, our alliance uses water as a reference, and the density of water is set to 1. I have already explained the concept of density to you.

Then we found that the density of most wood is lower than that of water, so wood can float on water.

Conversely, copper and iron are denser than water, so they sink when they meet water. "

Fang Yizhi is really interested in physics, but after all, he has only stayed in Taibei for a short time, and he has never studied in school.

A few days ago, Zhou Haoyu was mainly introducing terminology and new vocabulary brought by Zhu Tao to him, otherwise there would still be many difficulties in communication.

Fortunately, Fang Yizhi had learned Arabic numerals and algorithms a few years ago, and also learned a lot of scientific terms from "Xu Xiake's Travel Notes", otherwise it would have taken a lot of effort.

"Brother Zhou Haoyu, how is the density of the tile vat compared to water?"

Hey, as expected, he was born smart, and immediately opened up the problem.

"Yizhi asked a good question! The density of the tiles is obviously higher than that of water. If you throw the tiles into the water, they will definitely sink, but the tile vat can float on the water. Why don't you think about it?"

"Could it be the shape of a clay vat?"

"There's this reason." Zhou Haoyu looked at Fang Yizhi and laughed, maybe this is someone with great wisdom?He didn't think about these problems when he learned these things.

"Then...then...in this way, isn't it...doesn't it mean that copper and iron can float on water as long as they are in the right shape?"

Now Zhou Haoyu couldn't bear it anymore, this Fang Yizhi is really powerful, but he can think of it in a few words.

"Is it... really possible?"

Hearing Zhou Haoyu's answer, Fang Yizhi was surprised now.

"Our alliance has built iron ships that can float on water."

"What, is it really possible?"

"Yes, but it's useless, and only small boats can be made."

"Why is this?"

"You know about riveting, right? Iron ships need to be tightly riveted with iron plates or steel plates to prevent water leakage. We can't make such large iron plates, and the manual work is too expensive.

What's more, the iron boat can't move after it's built, and the sail can't move it, and the speed is too slow to paddle with human power. "

"Ah, what's the use of that?"

Seeing Fang Yizhi frown, Zhou Haoyu smiled again, he couldn't say that the alliance is researching the steam engine.

"Then find a way to make it move, get up!"

Zhou Haoyu first answered a few questions from Fang Yizhi, and then began to explain the basic textbook of alliance physics to him.

Fang Yizhi also learned the habit of taking notes with pencils while listening to the lectures, and listened carefully to the explanations, and the time passed quickly.

Zhou Haoyu is very familiar with the boat going up and down on the sea. Ever since he met Zhu Tao, he has been either a student or a teacher.

An hour passed, and the content of a chapter was finally finished.

Because it is only a physics course, Fang Yizhi needs to go back to observe and review the exercises after class for a few days after completing the teaching of a chapter.

"Brother Zhou Haoyu, since you are both descended from China, why don't you...why don't you submit to my Great Qin and seek the well-being of the common people in the world?"

After the course was over, Zhou Haoyu waited for Fang Yizhi to digest it as usual, and then answered some of his questions, but Fang Yizhi asked this question instead.

"Yizhi also thinks that we can solve the problem by submitting to Daqin?"

Zhou Haoyu pondered for a while, and then asked Fang Yizhi back. In fact, he has faced such questions many times over the years, but when facing people with different identities, he needs to answer them from different angles.

"I don't care about other things, I just heard that your annual income has far surpassed that of the Great Qin Dynasty, and my Great Qin court is only short of money and food, which makes Xiaoxiao show off his prestige. As long as there is money and food, northern exiles and thieves will no longer be nothing."

There are definitely a lot of gentry in the Qin Dynasty who are stupid. As part of the ruling group, under the imperial power society, it is too easy for these gentry to earn money, so that they rarely think about the future other than enjoying the present.

But this definitely does not include a considerable number of Confucian students who have the ambition of "regulating the family and governing the country and the world". Tongcheng, as a holy place for Ming thought and academics, has more Confucian students with the heart of serving the country.

Intellectuals with ideals and aspirations seldom confine themselves only in books. The so-called "cultivation, study and inheritance" of Confucianism also contains the purpose of letting Confucian scholars understand the sentiments of the people.

The Fang family in Tongcheng is not a Confucian family, and Fang Yizhi's ability to study abroad is also affirmed by the family.
