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

Qin Wan didn't expect that people in ancient times respected patented technology so much. She handed over her drawings, but these people didn't even think of taking them for themselves.

Qin Wan didn't say anything, which made Manager Li a little nervous, "Madam Zhao, is that not possible?"

Qin Wan came back to her senses and said, "Okay, of course. Here comes the money again."

She had used up a lot of the materials for the bullets, so of course she had to buy some new ones. Also, iron was not as hard as steel, and she knew some methods of purifying steel. Qin Wan wanted to try it when she had nothing to do, and then make a sharp dagger.

"Okay, I wonder how much Manager Li plans to spend?"

Shopkeeper Li originally wanted to offer 50 taels of silver, but Qin Wan did not agree immediately, so he raised the price, "80 taels of silver, I wonder if Madam Zhao is satisfied."

Shopkeeper Li paid this money because the rapid-fire crossbow was completed a few days ago, but Qin Wan did not come to pick it up in time, and it was seen by a nobleman, who also ordered a set.

Manager Li had already received the deposit, so he was so generous to Qin Wan.

Qin Wan didn't hesitate. "Deal! Shopkeeper Li just needs to give me another 72 taels of silver."

Qin Wan knew that the reason why Manager Li would pay was entirely because she had the support of the Zhenbei Marquisate. Besides, the drawings had been seen by others, so he could have done it secretly behind her back. Now that he was willing to pay, he was already a gentleman.

When Shopkeeper Li saw Qin Wan agreed, he immediately smiled and said, "Madam Zhao, please wait a moment. I will go get the money right away."

Qin Wan had already put away the crossbow and picked up the bag of pistol parts.

Caihuan and Caiping didn't expect that Qin Wan could earn 80 taels of silver just by drawing a random picture.

They immediately felt that the handkerchiefs in their arms no longer smelled good. They embroidered them stitch by stitch, and each handkerchief only cost 50 cents.

Soon, Shopkeeper Li took out the silver and said, "Mrs. Zhao, please check it and see if it is correct."

Qin Wan always valued money. She counted it herself and found seven ten-liang silver ingots and one two-liang silver coin.

"The numbers are all correct, Shopkeeper Li, is the old gentleman here from that day?"

Shopkeeper Li shook his head, "Old Man Chu didn't come today, what other weapons does Madam Zhao have to make?"

Shopkeeper Li's eyes were bright at this time.

Qin Wan shook her head. She would not reveal the machine gun blueprints. She just wanted to ask the old gentleman a few questions. "No, since the old gentleman is not here, forget it. Shopkeeper Li, I'll take my leave first."

Shopkeeper Li personally sent Qin Wan to the door of the store. Coincidentally, at this moment, a tall figure appeared.

Qin Wan and him were separated, but she recognized who he was. It was Master Xie whom she had seen from afar that day.

Qin Wan didn't stop and walked towards her own carriage.

Xie Yu'an also glanced at Qin Wan. In fact, in this era, there were very few ladies coming to the blacksmith shop. If she was a farm girl, it would be normal, but Qin Wan was obviously not one of them.

Xie Yu'an had a good memory, and when he came to Yanbei City, he naturally sorted out all the relationships in the city, including the situation in the Zhenbei Marquis Mansion.

After retracting his gaze, he asked Shopkeeper Li, "Shopkeeper Li, is my custom-made crossbow ready?"

Shopkeeper Li stretched his neck and breathed a sigh of relief when he saw that the carriage outside had moved.

Oh my goodness, what a coincidence, these two almost ran into each other.

If he were caught, he would be so embarrassed.

"Thank you, Master. The crossbow is ready, and so are the arrows you ordered."

Xie Yu'an was very satisfied, "Okay, please bring it out, shopkeeper!"

Qin Wan had sharp ears, and even though she was sitting in the carriage, she could hear the word "bow and crossbow". She guessed that Mr. Xie must have ordered the one she had.

However, she accepted the silver, and was even with the blacksmith shop.

Afterwards, Qin Wan went to the pharmacy again and bought saltpeter and sulfur. Because of the unexpected money, Qin Wan bought more.

Thinking that she might get scratched while testing the pistol, Qin Wan went to the pharmacy and bought ointment for treating scratches, as well as pills for treating minor daily illnesses.

In short, when I left the pharmacy, only 72 taels of silver were left out of the 40 taels.

Caihuan and the two maids had a new understanding of Qin Wan's squandering.

In their opinion, Qin Wan bought useless things, which was a waste of money.

Finally, Qin Wan went to the grocery store again and bought a few copper basins and limestone.

After some shopping, Qin Wan finally finished her shopping. "Let's go back home!"

Cai Huan said at this time: "Madam, can we go to the cloth shop to have a look?"

"Oh? You want to buy clothes?"

Qin Wan didn't know how to make clothes, and she had forgotten that women at that time would cut and sew their own clothes.

Cai Ping interrupted, "Madam, we want to sell the handkerchiefs we embroidered."

Qin Wan thought she was a very good boss, "Okay, let's go to the cloth shop."

So, everyone went straight to the cloth shop. When Qin Wan saw the finished clothes, she couldn't help but bought five new sets of clothes. Of course, they were all made of ordinary materials, the kind of cotton clothes that ordinary people would wear.

Her clothes are very worn out when she does blacksmithing.

The cloth shop owner escorted Qin Wan out with a smile on his face, "Madam, you are welcome to patronize our Qixiang Cloth Shop again next time."

Qin Wan nodded, "Okay, please stay, Madam Boss!"

After Qin Wan got on the carriage, the proprietress turned around and looked at her husband with a smile on her face, "Hey, I finally sold those clothes that I had wasted my money on."

The cloth shop owner smiled and said, "Well, I met the goddess of wealth today. There are not many ladies like today who are rich and not picky about fabrics."

"That's right. Next time I make ready-made clothes, I will definitely choose that kind of good material."

The cloth shop owner shook his head and said, "Forget it, let's just sell cloth honestly and don't copy the shop across the street."

"That won't work..." The couple started discussing the development of the cloth shop again.

Qin Wan was sitting in the carriage, still regretting that she didn't see the old blacksmith today. It was not easy for her to come out.

At this time, the old blacksmith that Qin Wan was thinking about had been taken to the military camp.

"My Lord, that crossbow was made by this old man."

Zhao Zhen took the cotton cloth and bandaged the wound on his arm, "Oh? Old man, did you really make that crossbow?"

Chu the blacksmith came to the military camp and didn't dare to lie. "My Lord, that was a customer who came to the shop to order. She provided the blueprint of the crossbow, and I made it according to the blueprint."

Zhao Zhen became curious, "Who is the person who made the reservation? You left your name, right?"

The imperial court strictly controlled iron products, and buyers could also be traced.

"My Lord, that person claimed to be the eldest lady of the Zhenbei Marquisate!"

Zhao Zhen: “….”

Zhao Zhen didn't expect that he would be asking about his own family, and his newlywed wife whom he had only met a few times.

Zhao Zhen narrowed her eyes and became curious about Qin Wan.

Xiao Jingrui didn't expect it to be Qin Wan. He had tried the crossbow and found it very sophisticated.

Zhao Zhen couldn't believe it, "Did she draw that blueprint?"

Chu the ironsmith was also not sure, "This old man has no idea either."
