Although such a thing was long as he expected, after the content of the letter was published, a faint smile appeared on his cheek.

After putting the letter aside, his eyes fell on the map on the wall not far away. This was exchanged in the system after he returned from attacking the Turks.

This world is too big, and the places occupied by the Tang Dynasty are too small. The Tang Dynasty's country cannot be just the Central Plains, and those overseas places are also places that he needs to conquer in the future.

He never showed his ambition in front of anyone, and even Li Shimin would not have thought that his ideas were so bold.

"Why is Your Highness here today?"

Seeing the little queen mother, Li Chunfeng, who was preparing to give a lecture, greeted him with a smile on his face.

"When you have nothing to do, come and join in the fun!"

After finishing talking with a smile, Xiaozheng sat down right beside him and planned to listen.

"Your Highness, otherwise, you will talk about this class?"

Everyone knows that the students in the academy like the most is to listen to Your Highness’s class. Even the gentlemen like them will have different understandings every time they listen to Your Highness’s class.

Xiao Zhengtai waved his hand gently and signaled that he was just to listen, not to give a lecture.

This kind of thing has happened before, so Li Chunfeng did not give in, but began to talk about today's course.

What surprised Xiao Zhengta was that today's course actually talked about the earth.

A class passed quickly, and all the students were so drunk that many were even confused.

The earth is well interpreted by a sentence that the sky is round, but no one can confirm why the earth is round.

"Your Highness, do you say the earth is round? This is really incredible!"

After class, Changsun Chong couldn't wait to run to Xiao Zhengtai and said with an excited expression.

"Learning is endless, and there is still a lot of knowledge in this world that you need to discover and learn."

After Xiao Zhengtai gave an ambiguous answer, he stood up and left. He had to discover the knowledge by himself and comprehend it would be more meaningful.

"Changsun, have you noticed that the lesson Mr. teaches today is very interesting! Do you think we really live in the same ball?"

Yin Yuan came over and asked Changsun Chong softly. If His Highness hadn't been here just now, he would really want to question Mr.

"Otherwise? Since ancient times, there has been a saying that the sky is round and the place is round, and I don't think this matter is fake."

After shrugging, Changsun Chong ignored him and turned around and went back to his seat to pack his things.

There are many students who have such ideas, and many people even discuss this course in private, and the controversy is getting bigger and bigger.

"Your Highness, you said this is a mess!"

In a few days, things became more and more serious, and the students were even divided into two factions, which made Li Chunfeng very helpless. He also taught according to the contents of the textbooks and had never considered that such a situation would occur.

"This is a good thing! Only when there is controversy will you be more motivated. This is better. A debate contest will be held in a few days. Let's verify it together. How about it?"

Xiao Zhengta was very optimistic about such a thing and directly put forward his own opinions.

"Okay, everything is up to Your Highness. I also want to see how Your Highness convinces them."

Li Chunfeng shook his head helplessly, turned around and walked outside, he wanted to arrange the debate.

"Your Highness, I don't understand one thing, and I hope your Highness can solve my doubts!"

At this moment, Xie Yan walked over slowly, holding a letter in his hand, with a look of confusion.

"Mr. Xie has something to do but it's okay to say it. If this prince knows, he will answer it for you."

"Your Highness, this is a friend I have made overseas. Every time I ask someone to send a message, time will not match. I even record the time many times, but every time I say differently from my friend, and it will be a day apart. I even say the daytime, and the other side says the daytime, and the other side says the daytime, which makes me very puzzled!"

Xie Yan said angrily, until now he was wondering whether his overseas friend was deliberately pranking him and making pranks with him.

"This question is easy to answer. The earth is round. When the sunlight cannot shine, it is dark night. Your friend is overseas, so the sunlight leaves our mouth. It should appear overseas, so it will be a day apart every time."

Before Xiao Zhengtai could speak, Li Chunfeng, who was beside him, started to answer.

"All nonsense!"

After these words, Xie Yan's face turned darker.

"Mr. Xie, this issue can be discussed in a debate in a few days. Please wait patiently for a few days."

Xiao Zhengtai was a little helpless. Li Chunfeng's explanation was correct, but this long-term question is really not a good answer.

"Your Highness, are you serious?"

Xie Yan looked at Xiao Zhengta with doubt. Could it be that the earth is really round? But how is this possible? If the earth is round, they are standing at this time. So, will the people standing on their other half be faced down?

Four days later.

On the Cuju field, all the students from Lishan Academy gathered to participate in today's debate.

"Hello, classmates, I am your senior, Changsun Chong. I'm very happy to see you come to participate in today's debate."

For today's debate, he did his homework and read a lot of classics just to completely block those guys' mouths today.

"Changsun Chong, don't mess with these useless things. It seems like you have won?"

Yin Yuan was very unhappy about such a move and immediately spoke up.

"Have you heard of it? Today's debate competition is about whether the earth is round."

"I've heard of this a long time ago."

"Look, is the senior who is full of confidence obviously confident?"

"Since ancient times, there has been a saying that the sky is round and the place is round. This debate seems to be unfavorable for Young Master Yin and others!"

...

As the debate competition began, the two sides had already burst into smell of gunpowder, which immediately made the students around them whisper.

"Sujing, you are watching the fun, not the ones participating in the debate, just keep your mouth shut!"

For the beginning of the debate, Cheng Chumo was so angry that his head hurt when these guys quarreled. He turned around and yelled at the students.

Suddenly, everyone closed their mouths in disappointment and did not dare to say anything.

"Okay!"

Qin Huaiyu said something unhappy and directly reached out and pulled Cheng Chumo.

I have to say that Cheng Chumo was quite intimidating in the academy. With his roar, the entire Cuju venue suddenly became much quieter.

"The prince now announced that the debate has officially begun. Please start your performance with representatives from both sides!"

After finishing talking with a smile, Xiao Zhengta stepped aside and looked at the representatives with anticipation.
Chapter completed!
