Xiao Mingzhan was influenced by her optimistic and positive attitude, and the corners of his mouth curled up slightly, "Okay, with Ranran as my backing, I feel at ease."

"Well, be down-to-earth and help me take proper care of my big brother."

"good."

At this time, a report came from outside Xiao Mingzhan's house, and everything was ready to set off.

He hugged Gu Xinran and left the space reluctantly.

Looking at the empty room, I feel a little disappointed. When will I be able to avenge myself and have peace and prosperity in my country?

Alas, civil unrest has broken out in Lan. Not only has it cost the people a lot of money and manpower, but countless people have been displaced. It is better for the war to end as soon as possible.

How can we win the war as soon as possible? After pondering for a while, I actually came up with an idea.

If you want to do your job well, you must first sharpen your tools. We can help improve weapons, but gunpowder is not an option. This kind of hot weapon with great destructive power is harmful to nature.

But bows and crossbows are fine. In the early days of the apocalypse, she relied on a five-chaser crossbow to save her life.

He got up and walked towards the study, took out a homemade charcoal pencil, and started drawing seriously on the paper.

The whole picture, structural diagram, and component diagram are all carefully displayed on the paper.

After the large army set off, Xiao Mingzhan, who was sitting in the carriage, looked into the space and found that his young wife had not left, but was writing and drawing seriously in the study. Out of curiosity, he slipped into the space again.

Gu Xinran was completely immersed in drawing and didn't even notice that there was an extra person in the study.

Xiao Mingzhan stood quietly behind him, watching carefully. The more he watched, the more shocked he became. This was completely different from the bow and arrow he usually used, but the principle was the same. It was just more convenient and more efficient.

Once this weapon is made, one archer can be worth three to five archers today. It is so powerful. With this weapon, fighting will be even more powerful.

His Ranran knows too much! He knows that Ranran has secrets, and he won't force her to tell him. As long as he knows that she has him in her heart, that's enough.

After Gu Xinran finished painting, she stretched and noticed Xiao Mingzhan with a burning gaze behind her.

With a look of surprise, he said, "Brother Xiao, it's great to see you again so soon. Come and see the five-shot crossbow I designed."

He pulled him to sit next to him and carefully explained the key points of making the quiver, pull rod, firing pin... as well as the working principle of the entire crossbow.

The more Xiao Mingzhan listened, the brighter his eyes became. He hugged Gu Xinran excitedly and kissed her on the forehead. "Ranran, you are really my lucky star. This crossbow is amazing."

Gu Xinran touched the place where she had been kissed and smiled shyly, "Hey, this is nothing, it's just a five-shot crossbow. Those crossbow carts and crossbow beds that can fire ten arrows at once are truly divine weapons for defending and attacking cities. Mine is more flexible and lightweight. If I equip a battalion of crossbows, I can achieve a surprise victory on the battlefield."

Xiao Mingzhan's eyes became even more blazing after hearing her words. He thought, "I know one thing, and I know everything. Now that I understand the principle of the repeating crossbow, how difficult will it be to make a crossbow cart and crossbow bed?"

The possibility of his father's death and the sadness and anxiety caused by the capture of Liaozhou all disappeared. Ranran was truly his savior.

He had to quickly order his men to make it, hoping it could be used soon.

He picked up the blueprints excitedly and said, "Ranran, is it okay for me to take these? I'll gather the staff now and tell them to hurry up and make them. Just wait and see the finished product."

Gu Xinran smiled and nodded, "These are specially prepared for you. Take them and get busy. I also need to rest."

He yawned as he spoke, rubbed his sore eyes, and continued, "Be careful on the road. Just let your subordinates do the work. You should also make sure to rest."

Xiao Mingzhan nodded and slipped out of the space.

Gu Xinran had been on the road for more than twenty days and was very tired. He returned to Lingquan Courtyard and had a good sleep.

The next day, he woke up to Xiaomei's knock on the door. After having breakfast with his family, he took out the various pills he had prepared last night and distributed them to the corresponding people.

Everyone expressed their gratitude, and the happiest person was my third aunt. She only needed to take a small pill every day, which was much better than the days when she had to drink bitter medicine.

Then, under the guidance of my third uncle, we went to a small courtyard near the back door, which was filled with spirits, fruit wine, and various medicinal herbs for soaking in wine.

Duan Qingxiang wanted to help, but Gu Xinran deliberately said, "Third uncle, my master said that my unique recipe for making wine can only be passed on to the next sect leader. Otherwise, you can join the sect and take over the position of sect leader. It just so happens that I don't want to do this anymore."

When my third uncle heard this, he realized the matter was so important that he waved his hand and ran out of the yard.

Gu Xinran laughed and asked Xiaomei and Xiaolan to guard the door. She worked as hard as a tiger and finished it in an hour.

The remaining time cannot be wasted. It is a rare opportunity to come to the picturesque Yunzhou Prefecture, so I must take a good look around and replenish some things that are not available in the space.

Led by an old maid, several people came to the most prosperous commercial street in Yunzhou Prefecture. They visited cloth shops, clothing stores, jewelry stores, grain stores... They all went around to investigate the market and understand the prices.

The things her grandmother prepared for her were already complete. She didn't buy anything for herself, but she bought a lot of clothes and small items for her grandparents, brother, and Xiao Ba who didn't come to Yunzhou Prefecture.

Of course, Xiao Mingzhan’s gift was also indispensable. Thinking of her future husband, she shook her head and sighed, and decided to pay more attention to him recently.

She focused on the rouge and powder shop, looking at the skin care products, lip balm, and incense... She found that these things were of poor quality and high price, and there was no perfume in that era.

Her desire to make perfumes and skin care products became even stronger. It is said that the money of children and women is the easiest to earn, and such a good business opportunity cannot be missed.

While walking around, I saw the sign of "Ruyuanling Wine Shop" from afar. The shop is located at the intersection of the commercial street and the food street, with an excellent geographical location.

There was a long line at the door, with a constant flow of people, both men and women. Gu Xinran and the others mixed in the crowd and heard various discussions:

"It's truly a truly worthy spirit wine! I gave Grandpa a jar of longevity wine as a gift, and he's been taking two sips a day for just two weeks. Guess what? The trembling old man can now walk around freely!"

"Sister, look at my skin. Isn't it whiter and smoother? Wow, it's truly a beauty-enhancing wine!"

"Alas, the wine is good, but it's too expensive. This banquet will cost me a lot of money. But it's worth it to let foreign businessmen see the good wine of our Yunzhou Prefecture."

"Not too expensive, you get what you pay for. It's just that the purchase is limited and the quantity is so small. If you come too late, you won't be able to buy it, which is a shame!"

…

Gu Xinran smiled brightly after hearing this. Haha, looking at this situation, the winery is like a hen that can lay golden eggs anywhere.

She glanced into the store through the crowd. The layout was exactly the same as that of Jinzhou Prefecture. The people inside were busy, so she didn't bother them.

Just as he turned around, he ran into his third uncle who was inspecting the store. He smiled broadly and said, "Ranran, what a coincidence, let's go take a look together. This is my first time in this store. I've seen the account book and it really makes a fortune. Since you're the boss, you have to inspect it."

I can't offend my third uncle, so I'll just wait and see. Gu Xinran nodded. As soon as he entered the winery, he heard a harsh noise.
