Time Travel: The First Female Imperial Teacher of the Qin Dynasty

"Mr. Lin, this is mud," Zhang Han explained.

"Mud?" Lin Anlan was extremely surprised.

"Yes, it's mud." Zhang Han affirmed.

"Are you sure this is mud?" Lin Anlan confirmed again and again.

"I'm sure." Zhang Han nodded firmly.

Lin Anlan walked forward, picked up a small handful, and rubbed it. It was indeed the same as mud, but it was obviously not ordinary yellow mud. She looked at the former in surprise: "How did you do it?"

Zhang Han replied: "I followed Mr. Lin's method, found clay, and then added iron ore powder."

"Oh, that's how it is." Lin Anlan suddenly realized.

"There's one more thing." Zhang Han quickly opened the lid of another box, which was filled with neatly arranged floor tiles.

"Is this a brick?" Lin Anlan pointed at the brick and asked, "What are you doing with the brick?"

Zhang Han explained: "Mr. Lin, this is not an ordinary brick, it is made of mud."

"Oh?" Lin Anlan picked up a brick and looked at it carefully. It was indeed different from the traditional blue bricks and the color was slightly pale.

"You've thought it through very carefully." Lin Anlan praised.

"Thank you Mr. Lin for your praise." Zhang Han was very excited.

"Thank you for your hard work." Lin Anlan looked at Zhang Han with admiration in his eyes.

"This is what I should do." Zhang Han said modestly.

Lin Anlan scooped some powder with a shovel, threw it into the sand, stirred it evenly, then tested the adhesion himself and tested the firmness with a hammer. The results were perfect.

She took out a piece of paper and handed it to Zhang Han: "This is the ratio of mud and sand. Take it and you can produce it in large quantities in the future."

"Mr. Xie Ling." Zhang Han was ecstatic.

"Oh, there are these too." Lin Anlan turned back to the table, took out a dozen drawings and handed them to Zhang Han.

"Mr. Lin, what is this?" Zhang Han asked puzzledly.

Lin Anlan said: "They are all drawings of buildings, ironware and the like. I drew them for fun when I had nothing to do."

"These drawings are full of treasures." Zhang Han flipped through the drawings one by one. The more he looked, the more shocked he became. Each one was priceless.

"What is this?" Ying Zheng asked, pointing at one of the drawings.

"Glass." Lin Anlan took a look and replied.

Ying Zheng asked in confusion: "Isn't Daqin already able to produce colored glaze?"

"That's different. Although colored glaze is also glass, its color is too bright and not pure, and its workmanship is not delicate enough. Its aesthetic value is greatly reduced. The drawing I designed can make the glass more pure and transparent, and can better reflect its aesthetic value."

Ying Zheng sighed with emotion: "Girl, I don't know how to praise you anymore."

"I'll take these drawings." Zhang Han carefully put away the drawings, fearing that they might be damaged.

Lin Anlan shook his head: "It's useless even if there are more fun things. My heart is not here."

"The girl's heart is all over the world." Ying Zheng looked at Lin Anlan with burning eyes.

"Maybe." Lin Anlan did not comment.

"By the way, this is for you." Zhang Han suddenly remembered something, took out a switchblade from his arms and handed it to Lin Anlan.

"What is this?" Lin Anlan looked at the familiar switchblade in astonishment.

Zhang Han replied: "Switchblade."

"You did it?" Lin Anlan asked in surprise.

"Yes, it was made according to the drawings given by Mr. Lin."

Lin Anlan sighed: "I didn't expect you to produce it so quickly."

Zhang Han said: "The craftsmen in the Shaofu are all talented people, but they had no place to display their talents before. Now that they have the opportunity, they will naturally go all out."

"People are forced to do things." Lin Anlan agreed deeply.

"By the way, girl, what is the purpose of this project bidding conference?" Ying Zheng suddenly asked.

Lin Anlan said with longing: "It means finding workers to build houses. Now we have mud and red bricks, we can start building houses. With the status of Shaofu and the support of the national treasury, we can realize the dream of having cement houses all over the city."

"Project bidding conference?" Ying Zheng and Meng Yi looked at each other, bewildered.

"To put it simply, it is to let merchants participate in engineering construction and save the court's manpower and material resources." Lin Anlan explained.

"Merchants are profit-driven and I'm afraid they will take advantage of this." Ying Zheng said worriedly.

Lin Anlan said: "It doesn't matter. What Daqin lacks is merchants. Through this cooperation, merchants can be vindicated. However, the imperial court is in the driver's seat. They can only drink soup, and we have to eat the meat ourselves."

"How can we get them to willingly pay for the construction?"

Lin Anlan smiled grimly: "No need to spend money, no need to pay wages, they will be grateful."

"This..." Ying Zheng was stunned.

"Mr. Lin is truly a god." Meng Yi was filled with admiration.

"You are cheating again." Ying Zheng cursed with a smile.

Lin Anlan pouted and said, "I have a vicious heart. Is this the first day you know this?"

Meng Yi exclaimed: "Mr. Lin, your trick is too cruel, it is simply the originator of cheating people."

"Merchants have money. Letting them pay more will also be beneficial to the construction of Daqin."

"Mr. Lin is very smart." Meng Yi gave a thumbs up.

"Are you scolding me?" Lin Anlan said unhappily.

Meng Yi waved his hands quickly: "Absolutely not."

"Okay, let's eat." Lin Anlan took out a few jars of wine and a pile of food.

Ying Zheng looked at the pieces of paper that Lin Anlan took out, and asked curiously, "Girl Lin, what is this?"

"Drink, eat." Lin Anlan tore open the oil paper and took out a duck in pickled sauce.

"Mr. Lin, what is written on this paper?" Meng Yi looked at the densely packed symbols on the paper with a confused look on his face.

"Mathematics." Lin Anlan replied.

"Mathematics?" Ying Zheng and Meng Yi looked at each other in shock.

"These are some mathematical formulas and mathematical knowledge," said Lin Anlan.

"What's the use of this?" Ying Zheng asked puzzledly.

“It can simplify arithmetic and make calculations more convenient. These methods are very useful to businessmen and can shorten the calculation time by ten or a hundred times.”

"Really?" Meng Yi looked surprised.

"Yeah." Lin Anlan nodded.

"Girl, where did you learn this?" Ying Zheng looked curious.

"I taught myself." Lin Anlan said.

"Mr. Lin is truly a scholar." Meng Yi admired him very much.

Lin Anlan said calmly: "These are all elementary mathematics, nothing special."

"What are these?" Ying Zheng asked, pointing at the Arabic numerals on the paper.

"Arabic numerals."

Ying Zheng wondered, "Why are these numbers so strange?"

"These numbers are simpler and easier to calculate. I renamed them Daqin numbers," said Lin Anlan.

"This is too amazing." Meng Yi was shocked.

Lin Anlan smiled and said, "These are the most basic mathematical knowledge. There are more advanced ones. I will teach you after you have mastered them."

"This is enough for us to study for a few years." Ying Zheng sighed.

Lin Anlan shook his head: "These are the most basic things, don't worship me too much."
