Otaku Engineer in Great Tang Dynasty

The "Geography" textbook Li Er wanted to read is being "watched" by several university graduates at this moment~!

"Hey~! The earth under our feet is actually spherical~? How is this possible~?"

(Li Tai has long known that the earth is spherical, so he won’t be surprised to see these things)

At first, it was just that Xiao Deyan did not restrain his curiosity, and quietly opened the book that Li Tai left behind. When he saw the first page, he couldn't help exclaiming, an inexplicable exclamation. It also attracted the attention of the two scribes next to him, but Xiao Deyan couldn't control these at this moment. He had put all his mind into the book, and he wanted to find out~!

The first chapter of the "Geography" textbook compiled by Li Zexuan talks about the earth and maps. After saying that the earth is spherical, Li Zexuan gave some proofs that can be given under the conditions of this era to prove that the earth is spherical. .

After Xiao Deyan read it, it really felt like thunder was thundering, and his head was buzzing. The ideas in this book were originally intended to be refuted, but after reading this chapter, he could no longer speak his refutation. It's just that the earth is spherical, which makes it difficult for him to fully accept it for a while~!

"My God~! The earth under our feet is so big~! Datang actually only occupies such a small area~! There are so many countries in the north, west, and south of Datang~?"

"70% of the earth's surface is ocean and 30% is land~? How is this possible~?"

"The longitude line from south to north passing through the Taiji Palace is called the prime meridian or zero degree longitude. It increases from the zero degree longitude to the east and west to 180 degrees, and from the equator (0° latitude) to the south and north. The poles increase to ninety degrees, dividing the earth, and each place corresponds to a longitude and latitude~! Sis~! Who wrote this book~?"

"Who came up with this latitude and longitude line? It's too bold. He wants to use my Datang as a reference to divide the world~! This idea~! This bravery~! It's absolutely incredible~!"

At first only two people were attracted, but when they saw the highlights in the book, the three people exclaimed for a while, and finally attracted all the scribes in the house.

Gradually, with the passage of time, everyone in the house was shocked by the grandeur of the "pointing to the sky and painting the earth" reflected in this book. No one ever told them that the earth is round. No one has ever told them how big the earth is, how much land and oceans occupy each, and no one has ever divided the earth by latitude and longitude lines. Only after reading the first chapter of this book, these scholars felt that the worldview in their minds had already They have been completely subverted, and they are still in a state of bewilderment.

"Xiao Xueshi, Your Majesty sent someone to come and said that he was going to help His Highness King Wei take away the "Geography" he had read before~!

Just when everyone was shocked and did not say a word, a small servant walked in outside the door and bowed his hand to Xiao Deyan.

Seeing outsiders coming in, dozens of scholars gathered around the table quickly scattered around the table with guilty conscience.

After all, this book is Li Tai's private book, and it is illegal for them to read it without permission.

Xiao Deyan's face blushed, he stood up and looked at the young man and asked, "The "Geography" textbook~? What geography textbook~? Your Highness can make it clear~?"

Although the young man felt the atmosphere in the room was weird, he didn't dare to raise any questions. He directly replied: "His Royal Highness said it was the book he had read before~!"

Xiao Deyan suddenly realized that, he picked up the book on the table and took a look, some reluctantly handed it over, and said: "That's it. You can take it to the person sent by your majesty~!"

"No~!"

The young man took it solemnly, and then backed out.

Everyone in the room glanced at each other, and Xiao Deyan sighed: "So this book is called Geography~! It's really an amazing book~!"

Another scribe also sighed: "Yes~! Let’s not say whether the things stated here are correct or not. The person who can put forward these views is definitely a stunning genius~! Just this courage! With this courage, the old man can hardly stand it~!"

Xiao Deyan nodded in agreement and said, "Brother Xie is reasonable~! I just don't know who wrote this book~! Why did it appear in the literary museum out of thin air~?"

This Xie brother is Xie Yan, also a bachelor in the Li Tai Literature Museum, and one of the future compilations of "Kuo Di Zhi".

Xie Yan replied after hearing the words: "It seems that someone sent this book to His Royal Highness Wei in the morning. After receiving the book, His Royal Highness has been reading through it, and he didn't even eat lunch~!"

Xiao Deyan frowned and said, "His Royal Highness said that this book is the "Geography" textbook, textbook textbook, where does the school use this textbook~? I really have never heard of it~!"

Xie Yan thought for a while, and suddenly shouted in shock: "Yanhuang Academy~! Only such a strange existence as Yanhuang Academy can use such weird teaching materials~! And your Royal Highness made me wait for the past few days to collect the mountains and rivers. Zhi~www.ltnovel.com~ may have something to do with this "Geography" textbook~!"

When Xiao Deyan heard this, he agreed: "Brother Xie's analysis is good. In this case, the person who wrote this book can only be..."

………………………

"Pointing to the world and dividing the world~! This kid is so bold~! Not bad~!"

In the Ganlu Hall, Li Er received the book "Geography" retrieved by the people below from the Palace of the Wei Dynasty. After reading it for a while, he touched his palm and laughed.

The reason why it is right is mainly because Li Zexuan defined the zero-degree meridian as the meridian passing through the Taiji Palace. This makes Li Er, who pays attention to the holy name, feel very proud and satisfied.

As for the theory that the earth is spherical, Li Tai introduced it to him before, and now that it says it in the book, I am not surprised.

"Is this the world map~? Why is my Datang only occupying such a large area~? And why are there so many missing in my Datang's territory~?"

Turning the textbook back casually, a big map instantly attracted Li Er's attention. After looking at it carefully for a while, Li Er raised his head and frowned.

Li Tai gave a dry cough and explained: "Father, although Datang has a vast area, it is really only that big on the earth. As for why there is a lack, this is because Mr. Li is not very concerned about the mountains and rivers of my Datang. If I understand, I handed over the task of perfecting this book to Erchen~! After receiving the book today, I am planning to start perfecting~!"

Li Er nodded, he stared at the map for a long time, then raised his head, an indescribable look flashed in his eyes, and said to Li Tai: "Okay~! The blue bird, you go back~! This book's Perfect, you must pay attention to it~!"
