Li Jie invited Ma Hama and Guo Zhenglin to sit down in the official room by Li Jie, and immediately a scribe brought tea, and Li Jie asked: "Since the two of you are not sent by Guo Jianzheng, why did you come to me?" ”

I saw Ma Hama and Guo Zhenglin glance at each other, and then Ma Hama spoke: "Li Siji, today Ying Tianfu suddenly posted a notice, saying that you want to prove that the earth is like a ball in front of the imperial city in three days, do you know about this?" ”

"Of course I know, in fact, this matter was originally what I asked the prince to let the court announce!" Li Jie smiled slightly, after nearly a month of preparation, he now has enough certainty, and he has also heard the rumors in the city, so he simply uses the imperial court to announce it, so that more people can see it with their own eyes and expand their influence.

"What? It turned out that you asked the prince to announce it, so you are really sure enough to prove that the earth is like a ball? At this time, Guo Zhenglin, who had not spoken, finally asked with a shocked face.

"What, you're interested in how I prove it?" Li Jie looked at the two of them with some amusement, although they said that they were seeing him in private and had nothing to do with Yuan Jianzheng, but he would not believe the two of them so easily.

It seemed to feel Li Jie's suspicions, and Guo Zhenglin hurriedly explained: "Don't misunderstand Li Siji, although Yuan Jianzheng supports Gaitian's theory, it doesn't mean that everyone in Qintianjian supports Gaitian's theory, for example, I have always insisted that Hun Tian's theory is the right way, and the deputy director of Ma Jian Hui Ke also insists that the earth is like a ball!" ”

Li Jie has also been observing Guo Zhenglin's expression, and found that he looked sincere when he spoke, and it really didn't look like he was lying, but when he heard the name "Huihuike", he was confused, so he asked: "What is Huihuike?" ”

This time, it was the Maha Ma who explained with a smile: "The predecessor of the Hui Hui Branch was the Hui Si Tianjian, and most of the people in the department were Semu people who worked for Meng Yuan, and later His Majesty expelled the Tartars and restored China, and we also took refuge in His Majesty......

With Ma Hama's narration, Li Jie realized that when the Meng Yuan Dynasty reused the color people, there were many Central Asians and even Europeans in the Qin Tianjian, many of whom were missionaries, and their astronomical calendar was different from that of the Central Plains, but it was also quite desirable.

However, later Si Tianjian was changed to Qin Tianjian, and Huihui Si Tianjian was also merged into Qintianjian, and a separate Huihui Department was set up, and Ma Hama was called the deputy supervisor, in fact, he was mainly in charge of the Huihui Department.

"I see, so what did you mean by coming to see me?" Li Jie nodded first, and then asked again.

"I'm ashamed to say that although we insist that the earth is like a ball, and we have argued with Yuan Jianzheng a few times, but we can't argue with him, so we have been trying to find evidence that the earth is like a ball over the years, although there is no big gain, but we have also found some evidence, if Li Sijian needs it, we can provide some help." Mahama finally said what he meant.

Li Jie finally understood when he heard this, Ma Hama and Yuan Jian were having academic differences, but they were subordinates, and it was estimated that they were also suppressed in the officialdom, and now Li Jie and Yuan Jian were making a bet, it was like pie in the sky for them, of course, they were also worried that Li Jie would lose, so they took the initiative to help.

"And how can you help?" Li Jie suddenly asked with interest, although he was completely sure, he also wanted to see how far astronomy had developed in this era?

"This ......" I saw Ma Hama and Guo Zhenglin glance at each other, and then said with some shame, "Don't hide it from Li Si, all we have is some indirect evidence, such as when people stand on the beach, when they see the returning ship, they can only see the mast first, and then see the hull little by little, which shows that the sea surface is an arc, not a plane, and there are ......"

Guo Zhenglin and Ma Hama put forward some argumentation methods that they could think of, but they could only be indirect proofs.

Among them, Guo Zhenglin represents the Hun Tian theory of the Central Plains, and Ma Hama is influenced by the ancient Greeks and religion, and adheres to the European geocentric theory, and the two theories are almost the same.

Both men are quite accomplished in their respective fields, and the methods of argumentation they put forward are also varied, but most of them do not stand up to scrutiny.

"Thank you for your advice, but I already have a good idea of how to argue that the earth is like a ball, and I'll see it in three days!" Li Jie interrupted the two with a slight smile.

"Li Siji, do you really have confidence?" Ma Hama still asked with some suspicion.

"Don't worry, in three days, no one in this world will believe what Gai Tian said!" Li Jie laughed again, but he refused to say how he wanted to prove it.

Ma Hama and Guo Zhenglin also glanced at each other when they heard this, although they could see a little suspicion in each other's eyes, but it was not easy to question Li Jie now, so the two had to stand up and say: "That's it, then we won't bother Li Siji, and we will be there in person in three days, hoping to provide some help to Li Sijian then!" ”

"Okay, then I also hope that the two of you can personally witness the destruction of the Gaitian Theory!" Li Jie also stood up at this time and saluted, and after speaking, he personally sent the two out of the ordnance prison.

After leaving the ordnance prison, Ma Hama immediately said to Guo Zhenglin: "Brother Guo, in your opinion, is this Li Sijian really sure or false?" ”

"This ......" Guo Zhenglin also showed a look of embarrassment, and after a long while, he finally spoke, "I can't say for sure, but looking at the way he speaks, it shouldn't look like he's telling a lie, maybe he's really sure." ”

"Not necessarily, I heard that this Li Siji had suffered from madness before, and it is possible to say crazy things." Ma Hama guessed that some madmen were talking nonsense seriously, but they couldn't see the slightest flaw at all.

"That was all in the past, and now Li Sijian can get the attention of the prince, so as to enter the Zhan Mansion as an official, and I heard that he has made great contributions, and there was originally a reward, but because of the bet with Yuan Jianzheng, the reward has not come down, I think this person should really have the ability." Guo Zhenglin disagreed with Mahama's point of view.

"I also hope that he is really capable, but throughout the ages, how many brilliant people have wanted to prove that the earth is like a ball, but who can really come up with evidence?" Mahama also showed a pessimistic look at the end.

When Guo Zhenglin heard Ma Hama's words, he couldn't help but sigh, and his confidence in Li Jie in his heart was also much less all of a sudden, and after a while, he suddenly shook his head and said: "It's useless for us to guess now, everything will be known in three days!" ”
