On the second day of Jiuzhangtang's class, more than twenty supervisors spent a whole painful morning bombarded by Lu Sanlang's exercises. In the afternoon, Zhang Shou used the three words Tianyuan Shu to arouse the supervisors.
After gaining great interest, he threw out the killer weapon of the one-variable equation, then irresponsibly handed over the explanation task to Lu Sanlang, and left quietly.
It's hard to be a teacher, not to mention that he now has to attend up to eight classes a day, which is hard to bear. Naturally, he has to rely more on the self-study of Lu Sanlang or the supervisors.
Moreover, he was asked to explain the simplest one-variable equation to a group of supervisors who had no idea what an equation was. He felt that his patience was completely insufficient, and he was also very angry at the loss of Taizu's simple mathematics textbooks.
When he arrived at the University Archway of the Imperial College, he saw that the carriage sent by Zhang Kang was already waiting there. Of course, there was also Ah Liu who would always appear when you needed him. He had gradually become accustomed to such bumps and was tired.
He dozed off unknowingly after getting on the carriage for most of the day. It was not until finally there was a knocking sound on the wall that he suddenly woke up.
"Master, the Ordnance Bureau is here."
Zhang Shou patted his cheeks and finally regained his spirits. Then he got out of the car and found himself standing in a quiet alley. Not to mention the harsh knocking sounds of tools and even the sound of people talking.
His voice was almost inaudible, and it seemed very inconsistent with the three words "Ordnance Bureau". An official in green shirt came forward and took the initiative to clear up his doubts.
"The Ordnance Bureau's office is here, but the factory is underground. All the land nearby has been assigned to the Ordnance Bureau. Many of them are empty houses, so there is no sound. This is the first time Dr. Zhang comes here. I'm afraid he doesn't know the rules here.
Even the prince or even the prince cannot enter the weapons bureau unless ordered to do so, so my uncle asked me to take you to his other private residence here."
Seeing that the other party explained in detail, Zhang Shou immediately thanked him with a smile - it is a confidential unit, and it is normal to have strict rules. As for the map, it may be a very precious thing for those merchants and even the fleet, but for the Ordnance Bureau,
, should be more valuable than those important weapons and equipment, especially, what he wanted to see was the map of the world outside the Ming Dynasty, so it would not be surprising if he could bring it out.
Since there was no one else on the road, Zhang Shouxiao had no choice but to chat with the green-shirted official who was leading the way. Only then did he learn that the other party was Li Wei, an eighth-rank official from the Military Bureau. Although he was only one rank shy of a doctor of the Imperial Academy, he
He was not stupid enough to think that there was really only a slight difference between the seventh and eighth grades, so the other party behaved respectfully and distantly, so he stopped talking after asking a few questions.
When he stepped into an ordinary-looking courtyard, the man in front of him, Li Dianbo, suddenly asked: "Dr. Zhang, are you here to unlock the fourteen-ring exquisite box?"
Without thinking, Zhang Shou pretended to be stupid and said blankly: "What fourteen-ring exquisite box?"
Seeing Zhang Shou's confused expression, Li Dianbo naturally didn't expect that such a famous young talent like him would pretend to be confused, so he said in a deep voice: "That is a secret box that has been kept in the Ordnance Bureau for many years.
The ring text lock will cause self-destruction if you are not careful, so it has not been opened for decades. Dr. Zhang, your ability to decrypt is well-known, so I naturally thought that was why you came here."
Since he decided to pretend to be stupid, Zhang Shou naturally decided to pretend to the end: "Haha, I just have a small friendship with Uncle Weinan. They met last night. I was curious and hoped that Uncle Weinan could be accommodating and let me see this.
A map of all the kingdoms of the world.”
Li Dianbo laughed immediately, with a clear look of disapproval on his face: "There are all the countries in the world, and those alien lands are only dozens or hundreds of small countries at most. Dr. Zhang, you will know when you see those maps.
"
Regarding such a reaction, Zhang Shou couldn't help but become more and more confused. However, he soon knew the answer. Because when he stepped into a room in the middle and saw Weinan Bo Zhang Kang, this man was quite old, but he was still able to
Seeing that Xiongyi was not like a barbarian at all, he waved away Li Dianbook and then pointed to the east room.
"Because it's not an important thing, I brought it out. You can go in and have a look. Since you said you didn't want to lend it out and just wanted to take a look, I'll give you fifteen minutes. I think it should be enough, right?"
"Of course it's enough, thank you uncle."
Zhang Shou thanked him and immediately entered the east room without hesitation. Even during the day, the room was still lit with lights, and with the help of the light, he could see the three maps hanging on the wall at a glance. But because
The light was still not ideal. He only saw a rough outline, and then he discovered an unexpected item on the table below the map.
That's a huge globe.
His first reaction was that many people in the West do not seem to believe that the earth is round these days, because Columbus's voyage, which can truly prove that the earth is a sphere, has not yet begun. Even with Emperor Taizu, the sage and Ming Dynasty,
You have actually given up on the idea of a round sky and a round earth and believe that the earth is a round ball?
Just when he was suspicious, Zhang Kang's faint voice came from behind: "This is something left by Emperor Taizu. He said that he had a dream. He dreamed that he was taken high into the sky by the Emperor of Heaven and found this
The world is not a round sky and a square, but a ball, so I finally ordered the craftsmen to create this. Then I drew these lines and maps on it. Of course, I made more than a dozen at a time."
"Since this was made by Emperor Chengtian in a dream, the first of the three pictures is also a map drawn by placing a sphere on a flat surface. The next two pictures were compared after the fleet sailed.
Picture, although the small countries encountered are slightly different, the general outline of the land is similar. Emperor Taizu is worthy of being born from the sky..."
Zhang Shou, who had already approached, listened absently to Zhang Kang's introduction, but did not look at the map on the wall. Instead, he concentrated on looking at the longitude and latitude lines on the globe, and at the clear outlines of the seven continents and four oceans.
Look at the territory of the Ming Dynasty marked above, as well as the densely populated major countries on the European continent.
He was also someone who kept a huge globe at home and collected various historical maps of the world in his study. So after he fiddled with the globe carefully, he found that the positions of the seven continents and four oceans were not much different from what he had remembered.
, with considerable accuracy, he immediately judged from the approximate locations of the Kingdoms of Spain and Portugal that this was a world map from the 14th and 15th centuries.
At that moment, he had completely concluded that Emperor Taizu was not only a map controller, but also a map controller with full map skill points. It was absolutely impossible for him to mark the Kingdom of Spain while also thoughtfully marking Cass.
The Kingdom of Ti and the Kingdom of Aragon, not to mention, he couldn’t remember the dividing line that was as winding as a dog’s gnawing!
But soon, his eyes were attracted by the color blocks representing the Ottoman Empire and the Byzantine Empire. At this time, Zhang Kang's voice sounded in his ears at the right time.
"After the big ship sailed across the sea, the imperial court naturally devoted all its efforts to searching for the larger countries in Emperor Taizu's dream, and these two countries were naturally at the forefront of the investigation. Although they are far away from our country, they are not of my race, and their hearts must be
We have to be on guard against the differences. But in the end, when several ships came back after all the hard work, the news they brought back was completely different. Dr. Zhang, you can look at the second picture."
Zhang Shou raised his head to identify it carefully, and finally found on the second map with distorted proportions that was difficult to read. The Byzantine Empire had lost Constantinople and its territory had shrunk. The Ottoman Empire, which was once dominant in later generations, except for the
To the east of the Aegean Sea, the land from the former Mysia, Lydia to Ephesus occupies a large area, and the forward has crossed Constantinople and invaded the former Thracian territory occupied by the Byzantine Empire.
land.
After recalling the expansion history of the Ottoman Empire, he vaguely realized that the territory of the Ottoman Empire should not be completed yet. But Zhang Kang's next words suddenly made his heart move.
"When Emperor Taizu came to the throne, he defeated the Timur state. Timur later paid tribute and became a vassal. To the east of the Timur state was the Ottoman state that Emperor Taizu dreamed of. Emperor Taizu ordered
The frontier army continued to recruit troops from the north and defeated Timur's army repeatedly. Timur could only press westward, and the Ottomans suffered several major defeats. Later, when his strength increased and he wanted to march eastward, he died on the way.
Later, after our big ship arrived and made inquiries, we found that the Ottoman territory was nothing more than this..."
Before Zhang Kang could continue, Zhang Shou suddenly asked: "When was this map drawn? Will there be any further information to draw it again?"
"No. That area is really too messy." When he mentioned it was too messy, Zhang Kang frowned and then said nonchalantly, "And those small countries in the west are fighting each other every day and are very poor. They can't bring much profit from trade.
, In contrast, India is rich in produce, so before the Yingzong, most of the fleets sailed south through the Strait of Malacca and sailed to India. Some people in the court had ideas, but for some reasons, they were shelved.
.”
The purpose of the imperial official ships going to sea was to find out whether Taizu's descendants were scattered abroad, which would endanger the royal rule in the future; while the purpose of private merchant ships going to sea was to dump goods in exchange for gold, silver, gems and spices. In this way, the original territory was still
The Ottoman Empire, which had not expanded to the largest extent, was despised because it was defeated repeatedly by the Timurid Empire. The small countries in Europe were also despised.
Before the discovery of America, which was rich but backward, those small European countries could not produce much gold, silver, oil and water at all!
Zhang Shou glanced at the three maps on the wall and finally came to a conclusion.
The first one used the transversal McLaren projection map, which was most commonly used in the future, and drew the information on the globe on a flat surface.
The second picture is based on the first picture and has been modified based on the information on sea voyages. However, the modified information is limited to the Ottoman Empire, the Byzantine Empire and some small European countries, and many of the dividing lines are simple and crude.
Straight line, he knew that the fleet's knowledge of those countries was very superficial, and they had probably only visited them once or twice.
As for the third map, it basically followed the second map, but modified the central position to put the Ming Dynasty as the center of the world. The adjusted map revealed a strong sense of the Celestial Kingdom.
.
It must be said that Taizu hoped that the people of the country could open their eyes to see the world, but now it seems that the eyes have been opened, but the extent is limited.
In the final analysis, civil strife kills people. It is amazing that the Ming Dynasty has not fallen apart despite several civil strife!
He sighed secretly, then smiled at Zhang Kang and said, "Thank you uncle for granting my presumptuous request."
Seeing Zhang Shou's satisfied look, Zhang Kang couldn't help but smile: "I know you scholars like to say that it is better to travel thousands of miles than to read thousands of books. Now that you have seen the map, please pay more attention to the fourteen-ring lock.
"
"That's natural." He agreed happily, but Zhang Shou secretly chuckled in his heart.
