When it was dawn, Roger and his party walked out of Seville's gate.

They walked up to the spacious stone brick avenue to Port Cadiz.

Miledi seemed to have recovered his health, became energetic and confident again.

She was dressed in an Arab woman, and her headscarf covered her golden hair, but she didn't cover her face.

She rode on a horse in front of the team.

But Roger was a little in a bad mood and he didn't sleep well last night.

He had a dream, and in the dream he agreed to Carmen, and they had a good time.

In the morning, he gave the waiter with two beards an additional fee, which was to compensate the inn for cleaning fees.

The bearded waiter didn't want it at first, but Roger insisted on giving it to him, so he took it away and threw it into the counter without any knowledge.

Then the bearded waiter took the initiative to fill Roger's empty wine bag with sugar-filled mint tea.

If his boss saw his generosity, he would probably make his boss cry as much as he cried.

Roger shook his head and didn't think about it.

He saw that the boy Idrissi and the girl Aisha were happily fiddling with Roger's wine bag in the caravan with the curtains open.

The wine bag sprayed mint tea out from the mouth of the mouth, and the two children shared the sweet fragrance one by one.

Roger suddenly thought that there were many problems that had not been cleared with the boy.

At that time, at the Colosseum of the Romans in Merida, the boy was halfway through the conversation, and the demon son, Evelit, came, and later forgot to ask.

Roger thought that the boy said he had skipped school from college and had to look around.

He thought, where did the university come from in the Middle Ages? This boy named Idrissi would not be a time traveler, right?

He was determined to ask clearly.

But Roger didn't want to attract the attention of others.

He thought about it and thought that saying a few codes was a good choice.

So Roger rode his horse and approached the caravan.

He said to Idrissi: "Ask you a question, hydrogen, helium, lithium, beryllium boron, what is behind it?"

Several question marks seemed to appear on Idrishi's forehead, and he said, "What, what did you say?"

Roger felt that his code might be too difficult.

If modern people do not study chemistry well, they will indeed not be able to continue.

He asked again: "What about the next sentence of 'strange changes and even changes'?"

"No, I don't know, what are you asking?"

Roger thought about it and left school for too long, so he couldn't remember what the next sentence was.

He asked the simplest question: "Have you ever eaten scrambled eggs with tomatoes?"

"I've eaten scrambled eggs, what is tomato?"

Roger frowned secretly.

He thought, was it wrong? Didn’t this guy travel through time?

He thought again, maybe this guy is pretending, I'll try him again.

So Roger changed his opinion:

"Did you know that the earth under our feet is a flat plate. When you walk, walk to the edge of the flat plate, and take another step, you will fall."

Idrissi smiled and said, "No, the ground under our feet is not a flat plate, it is a ball."

“If we keep walking in one direction, we will go around and return to the starting point.”

"Ha, I know, I know! Honestly, where did you come from?"

Idrissi was startled by Roger who suddenly became excited.

He said: "I was born in Ceuta and then followed my parents to Cadiz and they asked me to go to Cordoba..."

"I'm not asking this! OK, I'm not honest. Then I'll ask you, what's going on in college? Where did you go to? Where did you come from?"

"What's wrong with the university in Cordoba? I'm there to study law, Arabic language and literature, theology and philosophy."

Now Roger was a little uncertain, and he asked, "Is there really a university that teaches knowledge?"

Aisha interrupted from the side, "Yes, yes, when I passed by Fez, I also saw a university, Karuin University, but they didn't let me in."

Miledi didn't know when he came to Roger.

She also interrupted: "There is also a university in Bologna in northern Italy. It was founded more than 20 years ago by the Roman jurist Inelio, who teaches law and medicine."

Roger was a little stunned. There were already universities in the Middle Ages in 1110 AD? More than one university?

He asked a little embarrassedly, "Idrissi, you said that the earth under your feet is round, and you haven't walked around again, how do you know?"

Idrisy showed off his mastery as a scholar and explained very seriously:

“You will know more about reading.

"More than 1,500 years ago, a famous ancient Greek mathematician, Pythagoras, and his disciples, first proposed the idea that the earth was spherical.

"They advocate using mathematics to explain the universe, believing that among all stereoscopic figures, spherical shapes are the best.

"They believe that the appearance of the universe should be spherical, and all celestial bodies in the universe, including the earth, should be spherical.

"After more than 100 years, the famous ancient Greek scientist and philosopher Aristotle made an argument that the earth was spherical.

"Aristotle observed the astronomical phenomena and inferred that the shape of the earth was spherical from the projection of the earth on the moon during lunar eclipse.

"Later, the ancient Greek astronomer Elatostelli calculated the circumference of the earth using the difference in the incident angle of the sun in the two wells of Alexander and Thebes."

Roger was shocked. He thought, is it true? BC people calculated the circumference of the earth.

Idrissi was still preaching: "There is a famous saying you don't know if you have heard it.

“‘Give me a fulcrum, and I can pry the entire earth.”

"This sentence was said by Archimedes more than a thousand years ago. If the earth was flat, how could he pry it?"

Roger thought hatefully, why can't you pry the tablet? Just pry it over?

Idrissi continued, "You may not know about Pythagoras, Aristotle, Elatostney.

"You always know Archimedes, he is from Syracuse.

"Do you know where Syracuse is? In Sicily. Do you know what Sicily?..."

Roger, Earl of Sicily, couldn't stand it anymore.

He blushed and rushed to the front of the team.

He thought that he was embarrassed by the time travelers again, and was actually educated by the medieval indigenous peoples that "the earth is round."

He ordered: "Go ahead at full speed."

Roger ran towards the wind, and his heart gradually became angry and embarrassed.

He thought, this kid did it on purpose, he did it on purpose.

It was because he asked something that the boy could not answer that he deliberately mentioned some ancient Greek figures that he didn't know.

He made me, a time traveler, look like an indigenous person who had never read books.
