Roger turned around and looked at the rabbi's dim eyes.

He knew it would be cruel to continue disturbing the old man at this time.

But Roger said, "That, Rabbi, I know you're very sad now."

"Yes, I'm very sad. I sent out a team of guys, but I don't know how many of them can come back."

"Well, maybe, there is a way to make you less sad."

“No.”

"There is a proverb from the East: There is no itch to have lice, no worries if you have too much debt. Perhaps, if you have another sad thing, you won't feel so sad."

"What do you want to do?"

"I want to ask you to borrow some money."

"you......"

"Do you think it's better now?"

"I......"

"I know you have no money, but you Jews must have hidden money, you can raise it or ask them to borrow it.

"I didn't want you for nothing. I asked you to borrow, and at the interest rate of usury, nine out of nine and thirteen, the profit will be increased. No problem, I agree."

"You didn't think so."

"Who said that I wrote the loan note and built the city lord's emblem seal, you can't believe it?"

"But believe it, the city lord will definitely not admit it when he comes back."

"Then I'll give you a mortgage, how about Toledo City?"

"You're kidding."

"That city lord's mansion."

"You're still kidding."

"You can take any valuable things in the city lord's mansion."

"When I came out of the dungeon of the City Lord's Mansion, I only saw the bumpy walls."

"Wall? OK, I'll give you the wall."

"I'm already very sad. When will you tease me?"

"I didn't tease you. The walls of the city lord's mansion are made of good stones, you know."

"I know this. What do you mean, tear the wall and give me the stone?"

"Yes, the four buildings on the city lord's mansion form a rectangular frame, and I live in it.

"Fuck, I said why can't I run out? There is something wrong with this Feng Shui.

"I decided, I want to tear down a row of buildings and give you the stones, how about it?"

"If this is the case, it's not impossible..."

"That's it."

Roger found a pen, but he didn't see the paper.

He tore a picture in the Old Testament on the lecture stage and wrote the contract in the blank space.

"Your Excellency, what you have torn the Bible."

"That's right, let the Lord be a testimony."

Roger took out the city lord's emblem ring, dipped it in wax and poked it on the paper.

"Take it, go to the butler of the city lord's mansion. If you give him the money, I will find someone to demolish the house now."

"He will be sad."

"Then let him come to me, and I will give him something even more sad."

Roger left the synagogue with pride.

He didn't care about how the rabbi and the butler handed over. This was all the affairs of the lower-ranking people, and he only did the key things.

For example, find someone to demolish the house.

Roger came to the headquarters of the Castilla Mason Guild.

This building is not the tallest and most luxurious in Toledo. It looks like a few stone houses are stacked together.

After walking in, Roger did not see the luxurious decoration, and the simple lines and some stone sculptures came into view.

But whether it is outside or inside, Roger has a feeling that the architecture is beautiful.

He was immersed in it without realizing it, and he explored the source of beauty.

A noun appeared in Roger's mind, which was also what he learned from the Internet in his previous life.

"Golden division!" Roger couldn't help but shout.

"I didn't expect that the city lord also knows what he is doing."

Roger turned his head and saw a strong man with an honest look on his face, his hands were big, and there were many calluses in his palms. He could tell that he was a man who worked all year round.

The man introduced himself: "I am the president of the stonemason guild, Peña."

"Bah, bah, bah..."

Roger made a few times without making a correct pronunciation. There was a pronunciation in this word that made his tongue feel a little overwhelmed.

"It's Peña, why don't you call me Shi Tou? It's actually the same thing."

Roger looked at President Shitou and smiled honestly, as if it was his fault if Roger couldn't read his name correctly.

"President Shitou, did you build this house? It's very skillful."

"Sir, I was the one who was in charge of the construction, not the one I designed. It was one of my friends, Fibonacci, who helped me design it."

"Fibonacci, I seem to have heard this name somewhere."

Roger pondered for a while.

He raised his head suddenly, and he thought that the Fibonacci sequence that caused him to fail in his previous life was made by this guy.

He thought that the mathematical problems of medieval people caused great harm to modern students.

He joked that he might as well do him and “eliminate harm for the people.”

Roger asked: "Is Fibonacci here?"

“No, he is not here, he is from Pisa, Northern Italian.

“He followed his father to do business with the Arabs in North Africa. We communicated through letters.

“He told me the 'Gold Dharma' in his letter and suggested that I build a house according to his design.”

Roger didn't really want to kill a mathematician.

He asked, “Has Fibonacci ever said how he learned the golden division?”

"Fibonacci said that he learned from the Arabs, and to his knowledge, the Arabs learned from the distant Orientals."

Roger thought that the distant East was either India or China.

He was very proud to make a conclusion that he must have learned from Chinese people.

At the invitation of President Stone, Roger visited the entire building.

Then they sat down and rested on the balcony on the second floor.

Roger then remembered his purpose.

"President Stone, I..."

A neat "huha" sound in the yard downstairs interrupted Roger's words.

Roger stood up and looked downstairs. He saw a group of strong men in an orderly queue, practicing spears.

Roger instantly left his affairs behind him, and he felt that the situation in front of him was even more important.

"President Stone, what's going on?"

The president stood by Roger's side, he said:

"These are all brothers in our club, including stonemasons and apprentices.

"When we do construction, everyone needs to know how to cooperate. On the construction site, we also need to be disciplined and not messy, otherwise something will be easy to get into trouble.

"Since my grandfather's time, we have used military training to strengthen everyone's discipline and tacit understanding of cooperation."

Roger watched the training of these people for a while.

He felt that these people were much better than militia, and they were completely at the level of professional sergeants.

"President Stone, you know what we are doing now. I need them to join my troops and help defend the city."
