Bi Lin saw that there was indeed a small "Xu" word embroidered on the cuffs, and the thief was caught by the owner, she only felt that her face was hot for a while, and she had to smear ginger juice, otherwise her little face would be red into a monkey's buttocks.

"This ...... The surname Xu in the world is not a certain person for you, this is what I took in the Xu Guo Mansion, this is the mark of the Xu Guo Mansion! ”

The young man just smiled, "You don't have to argue, I don't recognize this word if I embroider it?" I'm not going to take your clothes off you. But I was scolded by my husband for what you harmed, so you must make amends to me. ”

"Want you to make amends?" Bi Lin smiled disdainfully, "No way! ”

"Since this is the case, then I can only be offended, you can come with me to Mr. Zheng to judge, and just return my innocence!"

As he spoke, he grabbed Bi Lin's wrist, and was about to get up, but there was a sharp pain in his hand, just now he was still holding the other party's wrist, but in a blink of an eye, it became the other party breaking his fingers.

The young man gritted his teeth and whispered, "Don't let go yet!" Otherwise, I'm not going to be polite to you, and my fists aren't vegetarian. ”

Bi Lin laughed softly: "Which one are you scaring about, if you really have the ability, you will be restrained by me, do you want to find someone to judge!" ”

"Naturally, I have to find someone to judge!"

"So you don't beg for mercy!" Bi Lin secretly added a lot of strength, the young man grinned in pain, cold sweat broke out on his forehead, and he only gasped, not shouting or screaming, just glaring at her viciously.

Bi Lin felt a little hairy in her heart, if she was restrained like this by Xiao Biao, she would have been crying and begging for mercy, does this stunned boy really want me to break my finger to know how powerful this girl is?

Just thinking about it, he suddenly had a pain in his head, and there were two crisp sounds, and a fan knocked on the door of each of the two people's heads, "You two little ghosts just run to the academy, and you dare to make trouble in the classroom, honestly, what is your name, see if I don't sue Mr. Zheng, deal with you well." ”

The young man took advantage of the strength of Bi Lin's hand to loosen, quickly broke free, got up and arched his hand: "My name is Xu Huizu, it was Mr. Ma who specially asked me to come over to listen to his lectures, the first time I came to the academy, I didn't understand the rules, and I asked the senior to be tolerant, so I don't have to tell Mr. Zheng." ”

"Xu Huizu?" Bi Lin tilted her head to look at the young man's appearance, and muttered, "No wonder it looks familiar, I haven't seen it for many years." ”

Ru Yu, who was wiping the blackboard, turned around and played the round, "Brother Huang, forget it." It's normal for a baby to fight, so why bother with it. ”

Huang Fugui nodded, "Since Mr. Ma called you here, forget it, listen to the class when you go back, don't mess around anymore!" ”

Xu Huizu thanked him again, "Thank you, senior!" ”

Bell ......

The bell rang outside, and the classroom immediately fell silent, and Ma Du walked slowly into the academy with his hands behind his back. A student saluted with everyone, Ma Du pressed his hand and motioned for everyone to sit down, his eyes swept around the classroom, and said with a smile: "I am really happy to see so many people, and I thought that no one would come to listen to this useless course, and I was afraid that I would not be able to save face and specially found a few people to support the party, it seems that I am too worried." ”

The students below laughed sneeringly, Wu Fuzhong got up and said: "Mr.'s class can broaden people's horizons, the elective course "Ming Geography" opened last year has benefited me a lot, if it is released in the future to do things for the functional ability to know the folk customs and customs, it will be able to get twice the result with half the effort, I believe that Mr.'s navigation class can also benefit the disciples for life." ”

"Wu Fuzhong said well, knowledge is always useful, and using it for a while does not mean that it will not be used for a lifetime, just like the money in your pocket, it doesn't seem so important to eat and drink at home, but when you want to go out, you find that your pocket is empty, then it won't work."

"That's the end of the, now let's get down to business!" Ma Du beckoned: "Xu Huizu, why are you running so far, come to the first row!" And Li Zengzhi has listened carefully to today's class, and I want to take the school exam for you when I go back! ”

"Oh." Xu Huizu responded, looked at Bi Lin, who was bowing her neck next to her, and went to the first row of the class and sat with Li Zengzhi.

"My classmates who have studied "Daming Geography" with me know that the land that supports and nurtures us is vast, complex and changeable, with the grassland Gobi in the north, the desert yellow sand in the west, the plateau stone forest in the south, and the boundless sea in the east.

The students all knew that Ma Du's class could ask questions at any time, and Ru Yu stood up from his seat and said: "Back to Mr. Hui, there is a saying that the sky is round and the place is round, but since I have seen the twists and turns of the coastline on the map of the Ming Dynasty, I know that the earth is not square, but the sky may be round." The sun and moon revolve around the earth at opposite ends of the earth, respectively. ”

"Ru Yu said it very well, but it was still wrong! I don't know if the sky is round, but the earth is round! Madu stretched out his hand and violently lifted the red cloth on the table, and a huge sphere came into view, "This is the world we live in!" ”

"Ball! It's a ball! ”

"How can it be a ball!"

"Then we're not going to fall off the ball!"

The students were chattering, mostly shocked and incredulous.

"Who said just now that it would fall off the ball, Ru Yu is not you, I remember that you did well in the exam, did you learn in vain!"

"Sir, you mean gravity?"

Ma Du nodded and said, "That's right, smart!" ”

"Sir, do you have any arguments to prove that the earth is round?"

"It's simple, another day you go to the dock to observe the departure of the big ship, you can find that the ship is not slowly getting smaller and disappearing in the line of sight, but slowly sinking, the curve of the earth limits our vision to about ten miles, of course, if we can climb higher, we can ignore the influence of curvature to see farther, if we can fly to the moon, we can see a big ball like us!"

"Did you ever fly to the moon?"

"Not really!"

"Then how do you know what the earth looks like when seen from the moon? Where are the moon and sun? How can there be day and night? ”

"This ...... Not the point! If we talk about it for a few days, we can't finish it, we have to talk about the sea! Ma Du hurriedly turned back to the topic, "Carry this to the middle for me, everyone will gather around and see it clearly!" ”

Madu walked to the middle and explained: "This is our home, I call her Earth, but most of it is surrounded by the ocean, and it is not an exaggeration to say that it is a water ball. This red part is the territory of the Ming Dynasty......"

The students immediately blew up, because the territory of the Ming Dynasty was too small, and in their hearts the Ming Dynasty should occupy the entire Eurasian continent, leaving a few small islands the size of sesame mung beans, which were specially reserved for the central country to pay tribute, not only these students, this is almost what all traditional literati think.

"Huh...... From this point of view, it is really not big, but in fact it is the most extensive and powerful country in the world......"

The students nodded in unison, looking as if they were taken for granted.

Ma Du continued: "Although the other places are wide, the country there is not as large as the Ming Dynasty and the capital, and even most of them are wild and uninhabited, in the north of the Ming Dynasty is Mongolia, and in the north of Mongolia is the vast ice field......"

He told the students what he told Lao Zhu in Penghu again, and all the students were amazed by the world.

"That's right, this world is much bigger than we imagined, the farthest place is 20,000 miles away, the road is far and difficult beyond imagination, there are no roads at all, but the sea gives us a chance, this is the reason why I take a sailing course, as long as we are fast enough to ship and stock up on enough food and water, we will have the opportunity to ride the wind and waves to reach Japan, Ryukyu, Nanyang, Tianzhu, and even the new continent on the side of the earth!"

Madu waved his fist full of passion, and at that moment a discordant voice appeared, "Sir, why should we risk leaving our parents' family and going to the Wild Lands? ”

This question hit the nail on the head and caught people off guard, and the whole classroom was silent, only the sound of breathing could be heard clearly.

Ma Du once assumed that similar questions were thrown to different people, and Lao Zhu had already answered them in Penghu, and he was pregnant with jewels and jade Qiongyao disdained rubble.

Zhao Desheng said: "If the emperor sets up a yamen overseas and lets my children and grandchildren go to be officials, then they will go, but it is better to stay in Yingtian and take care of it." ”

Shen Wansan said: "If the savages there can take out the things that are in their eyes, Shen doesn't mind going there to open a shop, but it is better for his wife and children to stay in Jiangnan and enjoy happiness." ”

Lao Cui said: "It's good to have land! But it's too far away, and I always have to come back to burn paper and sweep the graves of my ancestors, and I have to return to my roots when I die. By the way, where do savages eat Mahou eggs? ”

When Songhua eggs arrived in the twenty-first world, they were translated as "hundred-year-old eggs" by foreigners, and it is estimated that it is difficult to arouse their appetite, and I am afraid that it will not be easy to sell.

People leave their homeland, and the plot of the homeland of the Chinese is engraved in the bones, but where there is something to eat, few people go to other places to live, let alone overseas.

Counting the large number of Chinese people who moved overseas, almost all of them were in the troubled times of the late Song Dynasty, the late Ming Dynasty, and the late Qing Dynasty, and they had to move to Nanyang to survive, but now that the world is peaceful, there will be a brilliant and prosperous era soon, and a Ming Dynasty that is stronger and richer than in history, I am afraid that it will not leave.

So the student's question, Ma Du was prepared, he took out a small thing from his sleeve and stuck it on the globe.
