Compiling a book in these years is not a simple matter, like Luo Hongxian in order to compile "Guangyu Tu", I don't know how many books he consulted, and I don't know how much effort he put in, it's been five or six years, and he can only finish half of it.

This is a big reason why Yang Cong has not started compiling "The Principle of Knowing Things" for a long time, he has limited energy alone, and it is impossible to complete such a huge project, and at this time he has no books under his hands at all, if he is allowed to compile it alone, it is estimated that he will not be able to complete such a huge work until he dies.

However, this time was different, he happened to have some free time, and met Luo Hongxian, who was particularly interested in geography, so he decided to start compiling "The Principle of Gewu Zhizhi. Geography", as for the rest, you have to slowly gather talents before you can start.

In order to have a good beginning, Yang Cong also worked hard, these days he almost ran to Luo Hongxian as soon as the morning ended, the two discussed for a long time, or decided to make that kind of folio page, on one side is a simple map with symbols, on the other hand is a topographic map of mountains, rivers and cities, the two sides are compared, it looks very clear, I don't know how many times the previous map.

As for the content of the entire geography, of course, not only includes the territory of the Ming Dynasty, but also the whole world, however, Yang Cong only roughly remembers the outline of the world map and the general location of some major countries, and is really detailed to the mountains, rivers, roads, cities, etc., he is also blind.

What to do with this problem?

Yang Cong originally thought that this problem would be difficult to solve, and he might really have to catch a few businessmen from Europe, or directly fight with the navy of the colonial power, and capture his navigation map in order to slowly complete the world map, but unexpectedly, Luo Hongxian thought of a simpler way, that is, to turn the book.

He really didn't expect that there were still a lot of books in the Hanlin Academy, and the three attics in front of the Hanlin Academy were all used for books, and the books in them were simply as vast as a sea of smoke, and the dense bookshelves were full of books, and there were books in the whole three buildings!

When Luo Hongxian used to draw the "Guangyu Map", he turned out relevant books from it for reference, and he only turned the books that recorded the situation of the Ming Dynasty's territory, and he rarely went to turn over the rest, and he didn't have time to turn it over.

Yang Cong found that he really picked up a treasure, the collection of books in the Hanlin Academy was beyond his imagination, not only related books on geography, but also books on astronomy, equipment, metallurgy, water conservancy, etc., and the three attics were equivalent to a huge encyclopedia, but there were too many books and too many miscellaneous books, and a person could not finish reading them in his life.

As long as he has enough manpower, he can basically translate the scientific and technological knowledge of this era, that is to say, as long as he combines the knowledge of later generations with the content recorded in the collection of books in the Hanlin Academy, a set of "The Principle of Knowing Things" is almost complete.

Of course, this is also a rather huge project, he can't fully carry out it at this time, now, what he can do is to turn out the records of geography in the collection and add his own later generations to see and hear, and compile it together with Luo Hongxian into "The Principle of Knowledge. Geography.

This workload is also quite large, but it also brings him a lot of surprises, the collection of Hanlin Academy not only contains books that record the territory of the Ming Dynasty, but also atlases from the tribute of various surrounding vassal states, as well as detailed records of Zheng He's voyage to the West, as well as various geographical books in the Northern Yuan Dynasty of the former dynasty.

This guy, the former Northern Yuan Dynasty is a big empire across the entire Eurasian continent, they not only have a detailed map of their own territory, but also a detailed map of the hostile European continental countries, with these books, the terrain and landforms of the entire Eurasian continent are almost out, as for Africa and North and South America, just roughly mark it first, anyway, those places are basically colonies of European countries in this Age of Discovery, and there is no need to make too detailed marks on the map.

Yang Cong originally thought that the maps about the Eurasian continent on the "Kunyu Wanguo Quantu" were brought from Europe by Western missionaries later, but now it seems that this is not the case at all, the Ming Dynasty originally had relevant maps, but no one put them together and merged them into a complete world map.

This is not surprising, because people's energy is limited, like Luo Hongxian, who is obsessed with geography, spent five or six years to draw half of the map of the Ming Dynasty, he didn't even have time to look through the geography books outside the territory of the Ming Dynasty, let alone others, unless the emperor decreed, otherwise no one would be bored to do this, and the reason why "Kunyu Wanguo Quantu" was born was because Wanli was curious about the world.

It can be said that a rough map of the world can be drawn using the collection of the Hanlin Academy, and if you add Yang Cong's later experiences, the map drawn is even more comprehensive than the "Kunyu Wanguo Quantu".

This discovery really made Yang Cong and Luo Hongxian excited, and they were obsessed with "The Principle of Knowing from Things. Half a month passed in the compilation of the Geography Chapter.

On this day, Yang Cong still went down the morning court as usual, rested a little, and went straight to Luo Hongxian's room, but he didn't expect that Luo Hongxian already had guests there.

This person is Zhao Shichun, the editor of the Hanlin Academy, and he is also an idle guy.

Yang Cong has also heard of this Zhao Shichun's deeds, this guy can be described as a wonder, he is the first in Jiajing's five-year Bingxu Branch Examination, that is, Huiyuan, and at that time, Jiajing had a conflict with the courtiers because of the dispute over the Great Rites, so he did not hold a palace examination.

This guy, I don't know if he has too much sense of justice or doesn't match Jiajing, he just stepped into the official career and got on the bar with Jiajing, and if he has nothing to do, he will play and criticize Jiajing, it's not right here, it's not right there!

Well, you have been working against the emperor these years, and the result can be imagined, his career has almost been ruined.

Jiajing launched a fight to help who could carry it, and after he got a few letters, Jiajing was furious, and directly ordered him to be imprisoned and beaten for a few days, and then dismissed him from office!

However, almost ten years have passed since this incident, and Jiajing may have found out what was wrong, and reinstated him to the Hanlin Academy.

In other words, he is such a second-class and third-class talent, and he has been in officialdom for more than ten years, and he is only a seventh-grade petty official!

This guy, what are you doing with Luo Hong first?

Before he could ask, Zhao Shichun took out a copy of the fold as if offering a treasure and asked him to evaluate it.

Yang Cong opened the fold and saw that he didn't faint at the wrong point.

This guy, he actually wanted to criticize Jiajing again, he should not be superstitious about any immortal arts, but should be diligent in government affairs signal orders, extensive visits, and incorruptible .......

Big brother, can you be reliable, will you have good fruit to eat if you hand it over?

Do you really want to persuade Jiajing to be diligent in government affairs or do you want to slap others in the face, go against the emperor, don't you seek death!
