Li Jie invited Ma Hama and Guo Zhenglin to sit down by Li Jie's office, and a clerk immediately sent tea. Li Jie then asked, "Since you are not sent by Guo Jianzheng, why are you here to find me?"

Mahama and Guo Zhenglin looked at each other, and then Mahama said, "Li Sijian, today Yingtianfu Office suddenly posted a notice saying that you would prove that the earth is like a ball in front of the imperial city in three days. Do you know this?"

"Of course I know, in fact, this matter was originally something I asked the prince to let the court announce it!" Li Jie smiled slightly. After nearly a month of preparation, he was now confident enough, and he had heard of the rumors in the city, so he simply used the court to announce it, so he could let more people take a look at 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 confident enough to prove that the earth is like a ball?" At this time, Guo Zhenglin, who had not spoken, finally asked in shock.

"Why, are you very interested in how I prove this?" Li Jie looked at the two of them with some fun. Although they said they saw him privately and had nothing to do with Yuan Jianzheng, he would not believe them so easily.

It seemed that I felt Li Jie's suspicion, but Guo Zhenglin hurriedly explained: "Li Sijian should not misunderstand. Although Yuan Jianzheng supported Gai Tian's statement, it does not mean that everyone in the Imperial Heaven Prison supported Gai Tian's statement. For example, I have always insisted that Huntian's statement is the right way, and Hui Hui Ke, the deputy director of Ma Jian, also insisted that the earth is like a ball!"

Li Jie was also observing Guo Zhenglin's expression and found that he was sincere when he spoke, which did not seem to be lying. However, when he heard the name "Hui Hui Ke", he was confused, so he asked, "What is Hui Hui Ke?"

This time it was the Mahama who smiled and explained: "The predecessor of Huihui Department was Huihui Sitianjian. Most of the Seme people who served for the Mongolian Yuan. Later, His Majesty expelled the Tartars and restored China, and we also defected to His Majesty..."

Following Mahama's story, Li Jie realized that it was the first time that the Semu people were valued during the Yuan Dynasty. There were many Central Asian and even Europeans in the Imperial Heavenly Prison, many of which were missionaries. Their astronomical calendars were different from those of the Central Plains, but they were also quite desirable. After Zhu Yuanzhang established the country, he specially established Hui and Sitian Prison for these people, which was alongside the original Sitian Prison.

However, later the Sitian Supervisory was changed to the Imperial Heaven Supervisory, and the Hui Sitian Supervisory was also incorporated into the Imperial Heaven Supervisory, and the Hui Hui Department was established separately. The Maha Ma was named the Deputy Supervisory Office, which was actually mainly in charge of the Hui Hui Department.

"So that's it. What do you mean when you come to see me?" Li Jie nodded first, then asked again.

"It's a shame to say that although we insist that the earth is like a ball and have argued with Yuan Jianzheng several times, we can't argue with him. So we have always wanted to find evidence that the earth is like a ball over the years. Although we have not gained much, we have also found some evidence. If Li Sijian needs it, we can provide some help." Mahama finally expressed his purpose.

Li Jie finally understood when he heard this. Mahama and Yuan Jian had a disagreement in academic terms, but they were subordinates. They were probably suppressed in the officialdom. Now Li Jie and Yuan Jian were betting that it was a pie from the sky for them. Of course, they were also worried that Li Jie would lose, so they came to help.

"Then what help can you provide?" Li Jie suddenly asked with interest. Although he was very sure, he also wanted to see how astronomy in this era developed to the point?

"This..." Mahama and Guo Zhenglin looked at each other, and then said with shame, "To be honest, we have some indirect evidence. For example, when people stand by the sea, when they see the return ship, they can only see the mast first, and then see the hull bit by bit. This shows that the sea surface is an arc, not a plane, and there is also..."

Guo Zhenglin and Mahama spoke in the left and right, and proposed some argumentation methods that they could think of, but they could only be indirect proofs.

Among them, Guo Zhenglin represents the Huntian theory in the Central Plains, while Mahama was influenced by ancient Greeks and religions, and adhered to the European geocentric theory. These two theories are almost the same.

Both of them have great attainments in their respective fields and have proposed various arguments, but most of them cannot stand scrutiny.

"Thank you for your advice, but I have long been confident in the argument that the earth is like a ball, and I will know it in three days!" Li Jie interrupted the two with a smile.

"Li Sijian, do you really have confidence?" Mahama asked with some doubts.

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

Mahama and Guo Zhenglin also looked at each other when they heard this. Although they saw a little doubt in their eyes, it was difficult to question Li Jie now, so the two had to stand up and say, "That's the case, then we won't disturb Li Sijian. We will also be there in person in three days, hoping to provide some help to Li Sijian at that time!"

"Okay, I hope you can personally witness the destruction of Gai Tian!" Li Jie also stood up and said politely, and after that, he personally sent the two of them away from the Military Weapons Prison.

After leaving the military weapon surveillance, Mahama immediately said to Guo Zhenglin: "Brother Guo, in your opinion, is this Li Sijian really sure or fake?"

"This..." Guo Zhenglin also showed a embarrassed look. After a while, he finally spoke, "I can't say it, but looking at how he looked when he spoke, it shouldn't seem to be telling lies. Maybe he is really sure."

"It may not be true. I heard that Li Sijian had had crazy symptoms before, so it is possible to say crazy." Mahama guessed that some lunatics were talking nonsense seriously, but they could not see any flaws at all.

"That's all the time. Now Li Sijian can get the attention of the prince and enter the Zhan Shi Mansion as an official. I heard that he made great contributions and had a reward, but because of the bet with Yuan Jianzheng, the reward has not yet been received. I think this person should be really capable." Guo Zhenglin disagreed with Mahama's point of view.

"I also hope he is really capable, but from ancient times to the present, how many talented 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.
