The blacksmith lady is killing people in the harem, and her son is responsible for it.

Qin Wan chose a hammer and a sharp dagger. Thinking that she couldn't find iron ore at this time, she could only turn her attention to other iron products, so she chose a kitchen knife and some farm tools.

"Boss, I want all of these. Can you tell me how much they cost?"

Li Mubai frowned as he looked at all the iron products. "Madam, do you want all of these?"

Qin Wan nodded, “Well, can’t I buy it?”

The shopkeeper thought of the carriage at the Marquis' Mansion and shook his head, "It's not impossible, but Madam needs to register it. When the government checks, I have records here."

Qin Wan breathed a sigh of relief. As long as she was willing to sell it to her, it would be fine. "Well, can the shopkeeper calculate the cost?"

The shopkeeper took out an abacus and counted the money. "The kitchen knife is 80 coins, the sledgehammer is 1200 coins, the dagger is 130 coins, the shovel is 500 coins, and the sickle is 150 coins. The total is 2060 coins."

Qin Wan calculated it and found it was equivalent to more than 2 taels. She now understood the current prices.

Based on this calculation, the several hundred taels of silver notes she had on her were considered a huge sum of money.

Qin Wan counted the money she had on her and thought that her goal could be bigger. Instead of using Xiuzhen's pistol, she could go back and draw a bigger machine gun.

The money she had was enough to build it.

Qin Wan took out a small silver note worth five taels and handed it over.

"Madam, do you want the change in silver or copper coins?"

Qin Wan came just to get copper coins, because her bullets required copper.

Now that the restrictions on iron are so strict, she doesn't even dare to ask where to find pure copper.

"All they need are copper coins!"

"Okay!" The shopkeeper acted quickly and immediately returned 2940 coins to Qin Wan.

Qin Wan put three strings of copper coins in her bag, then took out the paper she had prepared long ago and handed it over, "Boss, I have something else to trouble you with. I want to order some parts."

The shopkeeper was now curious and took the paper, "Oh, let me see."

When the drawings of the crossbow and the parts diagram of Soo-jin's pistol came into the hands of the shopkeeper, the first thing he paid attention to was the crossbow.

Xiuzhen's pistol is just scattered parts that need to be assembled, but the crossbow is a finished product.

"Ma'am, I don't know if this is..."

The shopkeeper looked at it carefully, but didn't quite understand it.

Qin Wan immediately said, "Boss, I wonder if you could call the blacksmith over so I can explain it to you."

The shopkeeper nodded, "Madam, please wait a moment."

The shopkeeper immediately ran to the backyard. A moment later, a gray-haired old man came out and asked, "Where is the blueprint?"

Qin Wan handed over the blueprint of the crossbow, "Old sir, it's here!"

When the old man saw the blueprint, he didn't pay much attention at first. After he figured it out, his eyes lit up and he asked, "Little girl, where did you get this blueprint?"

Qin Wan smiled and said, "Old sir, you don't need to ask me where it came from. I want to ask if you can make it?"

The old man looked at Qin Wan with a questioning look in his eyes. "If I'm not mistaken, the crossbow on the blueprint is a rapid-fire crossbow. It's a weapon!"

Qin Wan found it funny. "Of course it's a weapon. The crossbow on the blueprint is an improved one, which is very suitable for women's arm strength."

The old man glanced at the carriage of the Zhenbei Marquis Mansion outside and said, "You are from the Zhenbei Marquis Mansion."

"Well, my name is Qin Wan, and my husband is Zhao Zhen, the eldest son of the Zhenbei Marquis Mansion!"

Qin Wan was not polite at all and dragged Zhao Zhen out for a walk. Sometimes, it is effective to use the power of another to bully others.

"Okay, we made the crossbow."

When I saw a few other scattered parts, I asked curiously, "What is this? Why is there no complete picture?"

How could Qin Wan say, "I made this for fun, old man, just follow the parts in my drawing."

The old man was now even more curious about Qin Wan, but knowing that Qin Wan could not speak, he was not in a hurry. With the drawings, he could study it himself.

He has been dealing with iron all his life, so he will definitely be able to figure it out.

“Okay, we can do all these things.”

The old man gave a positive answer, and Shopkeeper Li came to make a quotation, "Madam, I calculated that this is a custom-made product, including the labor and materials, the total cost is 10 taels of silver."

Caihuan gasped beside her. She really wanted to persuade Qin Wan.

Qin Wan also felt that it was not cheap, but she urgently needed these things for self-defense, otherwise she would feel insecure. "Okay, when can it be ready?"

Seeing Qin Wan's straightforwardness, the old gentleman replied, "Madam can come to the blacksmith shop to pick it up in seven days."

Qin Wan didn't expect time to pass so quickly, so she nodded, "Okay!"

Shopkeeper Li smiled and said, "Then please pay a deposit of 2 taels of silver, and the remaining 8 taels of silver will be paid when you come to pick up the goods."

Qin Wan did not touch the copper coins, but instead took out two taels of silver and gave them to the shopkeeper.

Caihuan and Caiping were both very confused. They thought Qin Wan was sick and bought some useless things.

They have been serving people for so long, but they have never seen any lady with this habit.

And those farm tools, you are not a farmer on the farm, what do you need them for?

He is usually stingy and unwilling to give rewards, but he spends money lavishly.

Cai Ping and Cai Huan, both with gloomy faces, helped Qin Wan get things.

The driver Zhang Bing saw that the three people had been in the shop for so long and had been waiting anxiously. Then he saw the farm tools in the arms of the two maids, "Caihuan, what are these farm tools for?"

Cai Huan glanced at Qin Wan and whispered, "This is what the eldest young master's wife wanted."

Qin Wan ignored the two people's muttering, put the big hammer in the car, and ordered: "Let's go to the grocery store."

Zhang Bing did not dare to hesitate, "Yes, Madam!"

Qin Wan also needs some other materials. The most important thing is that the bullet is composed of four parts: the shell, the bullet, the primer and the propellant. She already has iron and copper, so the only thing missing is gunpowder.

Gunpowder is mainly made of saltpeter and sulfur, supplemented by wood ash. You just need to buy some saltpeter and sulfur.

In the end, Qin Wan bought saltpeter and sulfur at the pharmacy.

Qin Wan came out and felt that everything went smoothly. She had bought everything she wanted. "Okay, let's go back!"

The coachman Zhang Bing immediately changed direction and headed towards the Zhenbei Marquis Mansion.

Unexpectedly, halfway through, the road was blocked.

"Caihuan, go and see what's going on ahead?"

"Yes, Madam!"

Qin Wan sat in the car, lifted the curtain and looked forward.

Soon, a team came over here. In the middle of the team stood a handsome man in a crescent-white robe, which made him look particularly stern.

Qin Wan was also very emotional, and complained in her heart: I came to ancient times just to see handsome men.
