My name is Chang An, your name is Gu Li

After Chang An dealt with the matters of Naji and Na Zheng yesterday, he stayed in the room alone, looking a little bored. He could only randomly pick up some books from his bookshelf to read. When the time came, he would eat and then go to bed on time.

This morning, it was still dark, not yet bright. He had just sat up from the bed when he heard a faint sound of footsteps coming from outside the courtyard. He was a little surprised. Was his hearing a benefit of traveling through time? His hearing was so sensitive.

The footsteps in the courtyard were definitely Huaiqin's. As Chang'an stood up from the bed, Huaiqin came into the room with a basin of water. As she placed the basin on the shelf, she shouted:

"Sir! It's time to wash up. After washing up, it's time to go to the Imperial Academy to study."

"what?"

Chang An didn't expect that after traveling through time, he thought he could be a stable second-generation official, playing with his lovely wife every day, but he never thought that he would have to go to school?! He had no choice but to accept his fate and go to the basin to start washing.

"Young Master, hurry up. The news about the diamond and platinum that you asked Huaiqin to inquire about yesterday has been sent back this morning. Let's go check it out after school."

After washing up, Chang An was helped by Huaiqin to put on his clothes. Then he carried the bookcase, put the diamond jewelry drawings in his arms, and went to the door with Huaiqin. The servant had already parked the carriage, Chang An got on the carriage, and told the servant:

"Just like yesterday, let's go buy some buns first, and then go to the Imperial College."

"Good son."

The carriage started moving, and Huaiqin sat opposite Chang'an as usual. Chang'an felt a little strange about this, but after checking his memory, he found out that Huaiqin was Chang'an's study partner. Chang Wenmeng originally wanted to find a book boy for the original owner, but was strongly rejected by the original owner, because Huaiqin had been serving Chang'an since childhood. Thinking of this relationship, the original owner gave Huaiqin such an opportunity to study together.

Arriving at the Imperial College, Chang An followed Huaiqin to his classroom. After finding his seat, he sat down. Because his seat was close to the wall, Huaiqin sat on the ground close to the wall.

After Chang An sat down, Huaiqin placed the book on Chang An's desk. The students passing by also greeted Chang An politely, and Chang An responded one by one according to his memory.

At this time, a student sat directly next to Chang An, bowed and greeted him, "Brother Chang."

"Brother Du." Chang An returned the greeting.

This is Du Chengming, the third son in the family. His father served as the Du Shui envoy in the court and was a good friend of Chang Wenmeng. Therefore, Du Chengming and Chang An also became friends since childhood.

"Brother Chang, I heard that you went to the house of the wealthy businessman Gu Ke yesterday. What was the matter?" Du Chengming asked with a gossipy look on his face.

"I'm talking about marriage. I've arranged a marriage with Sanniang from the Gu family." Chang An replied.

"Oh, Brother Chang, don't you usually disdain to meet with businessmen? Why did you go to propose marriage yesterday?"

"I have to do what my father ordered." Chang An said with a smile.

"This is not like you, Brother Chang. Could it be that the third wife of the Gu family is as beautiful as a fairy? Otherwise, you would never agree to this marriage." Du Chengming held Chang An's arm, his face full of expectation for his answer.

"Whether she is as beautiful as a fairy, you will know when you come to my house for the wedding." Chang An patted Du Chengming's hand and said half-jokingly, "If Brother Du also wants to experience the feeling of getting married, you can go back and ask Envoy Du to talk to you."

"Forget it then. It's better to wait until you have achieved success before getting married." Du Chengming changed the subject as soon as he heard what Chang An said: "Brother Cui, Brother Zhao, Brother Zhang and I have discussed it. After school today, the five of us will go to Zuiyun Tower to drink and compete in poetry."

"After school today, I have to deal with Najib's matter, so I won't go with you. When this matter is resolved, I will definitely compensate you."

Du Chengming originally thought that Chang An would agree immediately, but he did not expect that he would decline politely. This made him feel a little aggrieved: "It must be that Gu Sanniang is so beautiful that she could make Brother Chang so interested in getting married."

After hearing this, Chang An smiled faintly and did not respond. Just as Du Chengming wanted to continue speaking, the teacher came in, and Du Chengming was so scared that he hurried back to his seat. The teacher's surname was Zhou, and he looked a bit old, so he looked very majestic.

......

After a long morning, it was finally time to get out of school. Although Chang An had been asked to answer questions in class, he was able to answer them easily with the knowledge from his previous life and the talent he had in this life.

Chang'an carried the book box and came to the gate of the Imperial College with Huaiqin. The servants had been waiting there for a long time.

Chang An handed the book box to the servant and said, "Let's go to the West Market. Huaiqin will tell you the place later."

"Yes, son."

Chang An quickly got into the car with Huaiqin and asked the servant to drive there.

……

The servant drove to the West Market and stopped in front of a shop. Chang An got off the carriage and looked around: opposite the shop was a clinic, and to the right of the shop was a jewelry store. When he walked into the shop, the waiter saw a customer getting off the beautiful carriage and knew that a big deal was coming, so he hurriedly stepped forward and asked enthusiastically:

"Sir, do you want to buy something?"

Chang An nodded and said, "I heard that your family sells diamonds and platinum. Can you let me take a look?"

When the waiter heard this, his enthusiasm immediately waned by half - diamonds and platinum are both not very valuable things. Craftsmen may buy diamonds to make tools, but no one is interested in platinum.

"Okay, sir, please wait a moment, I will go get it right away." After the waiter said this, he turned around and left to get the goods.

Soon, the waiter brought a plate of things over, displayed it in front of Chang An, and said, "Sir, these are diamonds and platinum."

Chang An looked down at the tray, which was divided into two areas, with some diamonds on the left and two pieces of platinum on the other. He reached out and picked up a diamond, turned to the door, raised the diamond in his hand, and looked at it in the sunlight. After confirming that it was a diamond, he picked up a piece of platinum, squeezed it with his fingers, and then observed its color.

After all this, Chang An put the things back on the tray with satisfaction and asked, "How many diamonds and platinum do you have? I want them all. You can name the price."

The waiter was immediately happy when he heard this. Although diamonds and platinum were not valuable, quantitative changes would lead to qualitative changes. Roughly speaking, it was a big deal. He said quickly, "Sir, wait a moment. I'll go get it."

Huaiqin, who was standing behind Changan, saw his master doing this and asked in confusion: "Master, what do you want so many diamonds and platinum for?"

Chang An said: "Of course it is to make a unique engagement token that is the only one in the whole Tang Dynasty."

"What can this be made of?" Huaiqin was still confused.

"Don't ask, you will know in a few days." Chang An kept it a secret, and fortunately Huaiqin didn't ask any more questions.

Soon, the waiter came to Chang An with a piece of paper and said, "Sir, this is the list of diamonds and platinum you wanted. Do you think the price is right?"

Chang An took a look at the list. Ten pounds of platinum and four hundred grams of diamonds would only cost a few dozen taels of silver. He couldn't help but sigh in his heart: diamonds and platinum were really worthless in ancient times.

He handed the bill to Huaiqin. After taking a look at it, Huaiqin went to the counter, took out a sufficient amount of silver from the purse at his waist, and handed it to the shopkeeper along with the bill.

At this moment, the waiter in the shop came out with a small box and a large box. Chang An looked at the two boxes, came to the shopkeeper and asked, "Shopkeeper, can you do me a favor?"

"Sir, please speak." The shopkeeper said when he saw the man in front of him was so polite.

"To be honest, I want these diamonds and platinum to make jewelry. Could you trouble the shopkeeper to ask someone to help me carry these things and take them to the blacksmith and the jewelry store?" As he said this, he gestured to Huaiqin, who then took out another ingot of silver from his purse and placed it in front of the shopkeeper.

After seeing the silver, the shopkeeper smiled and said, "Okay, okay... Anyway, there are not many customers in the store right now, so let the doctor in the store go and help. What do you say, sir?"

"Naturally."

At this point, the waiter who was listening to the conversation picked up the box, which was very considerate. Then Chang An and Huai Qin led the waiter out and went directly to the jewelry store next to the store.

When the waiter at the jewelry store saw someone coming, he came forward and greeted, "Sir, do you want to buy anything?"

"We don't buy anything, but we would like to ask, can you help us make jewelry?" Chang An said, and was afraid that the other party didn't understand, so he added: "We provide the materials, and you are responsible for making the jewelry for us, and you set the price."

The waiter looked at Chang'an, then at the box beside him, and said, "I'll go ask our boss." After saying that, he turned and walked into the inner room.

When the waiter came out, another man followed him. Judging from his attire, he should be the shopkeeper.

The shopkeeper saw Chang An standing in the shop and asked, "Sir, do you want to make jewelry?"

Chang An nodded.

"What kind of jewelry do you want?"

When Chang An heard this, he took out the drawings from his arms, handed them to the shopkeeper, and said, "Please take a look and see if it can be made."

The shopkeeper looked at the drawings and the patterns on them and couldn't help but marvel at them. He asked, "Whose famous artist's drawings are these? It looks like if they were made, they would be extremely exquisite."

Chang An smiled and said, "This is not the work of any famous artist. I just drew it myself. I will use it as an engagement token for my wife when we get married. I will make one of each style. We can talk about the extra materials later."

The shopkeeper nodded, not quite understanding, and then asked, "Jewelry can be made, but the diamond part used for embellishment and as the focus seems to need to be polished. And this diamond is extremely hard, how should it be polished?"

“This is easy. No matter which diamond you want to polish, just use another diamond to polish it.” Chang An said.

The shopkeeper suddenly realized what was going on, and then he carefully put away the blueprint and said, "Since we already know how to polish diamonds, we will start working now. And since these jewels are what Master Naji needs, then we can hurry up and call in more people. It will be finished in two days."

Chang An heard this and knew that the gifts were in place, so he raised his hand and saluted, saying, "Thank you very much, boss. After the work is done, I will pay you twice the usual fee."

The shopkeeper responded with a greeting: "Then I would like to thank you first, sir."

After that, Chang An arranged some things in the jewelry store, then turned around and went out and returned to the shop. Just as he was about to get on the carriage, he suddenly saw an acquaintance standing in front of the clinic opposite the shop...
