Drive a RV and go farming in ancient times.

"This is?"

"Yeah, it's what you think."

As soon as Xu Huaiyi arrived home, he mysteriously pulled his wife into the study, took out something from the bag he was carrying, and handed it to her like offering a treasure, with a look of begging for praise on his face.

At first, Gu Huanxi thought he had brought her some gift, such as jewelry or books. It turned out to be a slightly thick piece of cloth. When she first took it in her hand, she didn't realize what it was until she saw the grid pattern outlined with red lines. Then she reacted.

Yet, I still find it a little hard to believe.

After reading it over and over again, Gu Huanxi spread it out on the desk, picked up a pen, dipped it in some water, and casually wrote the word "Gu". The mark was clear and the font was as black as ink. After waiting for a while, it gradually disappeared.

“Did you research this?”

"Well, what do you think?"

Gu Huanxi wrote a few more words and said sincerely, "Very good. Although compared with the one in my previous life, the quality is a bit rough and the cloth is not smooth enough, but at the moment, it is definitely a magical tool for calligraphy. Awesome, awesome..."

Xu Huaiyi was so pleased with the compliment that he said, "This is the primary version. It will be upgraded in the future. Please stay tuned."

Gu Huanxi heard this and said, "You don't have to be too particular about it."

Xu Huaiyi was stunned, "Why?"

Gu Huanxi lowered his head and wrote as he explained casually, "Most of those who buy this kind of water writing cloth to practice calligraphy are children from poor families. They choose this because it's cheap, not to save trouble, but to save paper and ink. If you keep improving, the cost will inevitably increase. Will we raise the price then? If we raise the price, then the meaning of inventing this will be small. If we don't, we can't treat business as charity."

Xu Huaiyi subconsciously said, "Those who can go to school are mostly from good families. How can they be short of this little money?"

Gu Huanxi glanced at him and said, "I'm not trying to discourage you. Those children may not like to practice calligraphy on the water writing cloth. Anyway, their families have enough paper and ink. The target audience of this thing must be poor students. Isn't the original intention of your invention for their sake?"

You only need to invest once and use it for a long time. It is very friendly to poor students. They only need to buy another brush. The cost of studying is high, and a large part of it is spent on paper and ink.

Xu Huaiyi was speechless for a moment, then smiled dryly and flattered, "Who said my original intention was for them? I did it for you. The things sold in the bookstore don't have any special features. This water writing cloth is unique at the moment and must be competitive. With it, we won't have to worry about customers in the future."

Gu Huanxi snorted and laughed, without commenting.

"Wife, what I said is true..."

"Oh, then take this as my appreciation."

Xu Huaiyi, "..."

Who could have wronged him? His original intention was really for his wife, well, 70% of it, and the remaining 30% was for the poor students who had to give up because of the high cost of paper and ink.

When he was fleeing from famine, he was deeply impressed by the scene of the children in the village holding branches and carefully writing on the ground. At that time, he thought of water writing cloth. However, he was busy later and had no time to think about it. It was not until his wife started to decorate the bookstore that he began to study it secretly.

After dinner, Xu Huaiyi showed the water writing cloth to Jiang Yong and asked for his advice.

Jiang Yong's reaction was much more excited than Gu Huanxi's. After understanding the use of this thing and experiencing it personally, the light and eagerness in his eyes were like a young man seeing the girl of his dreams. He praised it three times in a row, which showed his love and satisfaction for the water writing cloth.

Gu Xiaoyu also tried it out of curiosity, and immediately understood his father's intention, "Dad, use it to practice calligraphy, you can save paper and ink."

Xu Huaiyi nodded. "With it, it can at least reduce the burden on children from ordinary families."

"Are you going to sell it in the bookstore run by your mother?"

"Well, what do you think? Will there be a market for it?"

Gu Xiaoyu said with a firm tone and full of confidence, "Of course there is!"

Xu Huaiyi laughed, patted his head, took out a few simple boxes and handed them to him, "I'll share some with you and your fellow apprentices. Although our family has no shortage of paper and ink, you probably don't need them now, but after all, they were invented by Dad, so they are rare items. Keep them as a souvenir."

"How can it not be used? My son thinks it is very useful..." Gu Xiaoyu took it, opened the box, and saw a few things inside, "What is this?"

Xu Huaiyi explained casually, "These are the things you need to practice calligraphy. The materials used are all the cheapest, including brushes, water dishes, pen holders, and copybooks. They are made into a set, suitable for beginners. It's cheaper to buy a set than to buy a single water writing cloth."

Gu Xiaoyu deeply felt that the father he knew was a business genius with a great business mind.

Jiang Yong also agreed with this and asked curiously, "How much does this set cost?"

Xu Huaiyi said, "One hundred coins, what do you think?"

Jiang Yong asked in return, "Is there still a profit at this price?"

Xu Huaiyi nodded honestly, "Yes, there are, but not too many. But I don't plan to make a lot of money from it, so I'll just take it as small profits but quick turnover."

Jiang Yong sighed sincerely, "This is a blessing for the poor students. They should all be grateful to you. You have done them a great favor..."

Xu Huaiyi waved his hands hurriedly, "No, no, I'm not that great, what's the favor? I'm just doing business, it's not free, I also made a profit from it, although I didn't make much money, but it can bring popularity to the bookstore, which is better than anything else, I won't do business that will make me lose money."

Hearing this, Jiang Yong was at a loss whether to laugh or cry, "You are so humble and honest..."

Xu Huaiyi said shamelessly, "I am honest, but I am not humble at all."

Jiang Yong, "..."

He was silent for a moment, then changed the subject, "Have you arranged everything for the bookstore?"

Xu Huaiyi nodded. In order not to let his wife down, he had rehearsed the opening process several times in his mind. "Everything that needs to be arranged has been arranged, and the staff and gifts are also ready. Don't worry, I will make sure you don't lose face."

Jiang Yong nodded, "I am still confident that you can do the job, but what gift are you talking about?"

Xu Huaiyi smiled and said, "Keep it secret for now, you will know tomorrow."

"Do you still need to keep me in suspense?"

"Hehe, just think of it as giving you some anticipation. If I tell you in advance, there won't be any surprises."

Jiang Yong smiled indulgently, "Okay, then I'll wait and see. What about the banquet?"

Xu Huaiyi said, "We'll be staying at Shuiyunxuan. I've already booked a room with Su Zhe. For quietness, we've booked a courtyard. The environment is pretty good, and everything is elegant and refined, which is what scholars like. The dishes for the banquet were also discussed with Su Zhe. There are the specialty dishes and special dishes of the restaurant, as well as a few new dishes, which are recipes given by Ah Li's mother."

After Jiang Yong asked, he left with satisfaction.

Xu Huaiyi held the iced sour plum soup, relaxed his body, and drank half a cup comfortably. Noticing that his son was hesitant to speak, he said with a smile, "Just say whatever you want to say. Is there anything we need to avoid?"

Gu Xiaoyu said, "The master treats you much more attentively and kindly than he treats me."

Hearing this, Xu Huaiyi was stunned for a moment, then jokingly asked, "What's wrong? Are you still jealous?"

Gu Xiaoyu's porcelain-white face immediately turned red, and she said with some embarrassment, "My son doesn't have it!"

He really didn't feel resentful, nor was he jealous, but he couldn't really explain what his mood was.

Xu Huaiyi was amused by his reaction, "Hahaha, it's okay to be jealous, it's normal, but are you jealous of your husband or your father?"

Gu Xiaoyu, "..."

He really didn't!

Xu Huaiyi teased him for a while before saying, "Mr. Jiang is your husband. To maintain his dignity, he should not be too close to you, otherwise he will not be able to control you guys. You don't have to be so polite to me. I speak more casually, and I seem to be closer to him. In fact, he cares more about you."

Gu Xiaoyu felt that this was not the case, but he did not argue any more. His father just had a kind of affinity that made people want to get close to him. Not only Mr. Jiang, but even his uncle was rude and cold to others, but when he was with his father, he was casual and comfortable as if they were a family.

The next day, the bookstore opened.

The couple got up early. In fact, there was not much that Gu Huanxi could be used for today. After all, although she was the owner of the bookstore, she was restricted by this era and as a woman, she could not show her face in public to entertain guests.

Customers who came to buy things were greeted by the shopkeeper and the waiters, and the distinguished guests invited by Mr. Jiang were received by Xu Huaiyi. She just walked around in the backyard and took care of the children. However, she was not disappointed. After all, for someone with social anxiety, this arrangement was just what she wanted.

After dinner, the group went to the bookstore.

The plaque has been hung up, but it is still covered with red silk, waiting for the auspicious time to arrive.

The door of the bookstore was wide open, and the stone slabs in front of the door had been washed with clean water, making them as smooth as new. On both sides were placed a row of flower baskets, which were half a person's height and very delicately woven. The flowers and plants inside were colorful and the shapes were elegant and refined. There were also colorful flags hanging from the second floor, fluttering in the wind, which was also a fresh and creative idea.

Such a card is definitely eye-catching.

When Jiang Yong saw it, he couldn't help but praise it.

All the guys were dressed in new clothes and welcomed everyone in with renewed energy.

After entering the house, even Jiang Yong, who had been there several times before, couldn't help but be amazed again.

He was like this, so the children who had not been there were even more shocked. They held their breath, were overwhelmed, and everything they saw was curious.

“Is this a bookstore?”

"Oh my god, isn't it so beautiful?"

"Aunt is so awesome!"

The children all knew that the bookstore belonged to Gu Huanxi, and that she was the one who had been in charge of the decoration. The praise was sincere and full of amazement.

Gu Huanxi accepted it with a smile, "Go and have a look. If you like something, let the guys pack it for you when you leave."

The children didn't hesitate to thank him and went to have a quick visit. They looked so excited, as if they had discovered treasure and were going to dig for it.

Seeing this, Ah Li also staggered after him.

Speaking of which, the layout of the bookstore is nothing in later generations, but it is absolutely explosive now. No matter where it is, it is unique, quiet and elegant, which caters to the kind of extraordinary temperament that literati yearn for.

When you step into it, it feels like you are far away from the hustle and bustle of the city. There is silence in your ears, with only the sound of flipping papers. Leaning on the soft sofa, your whole body and mind gradually relax. There are no more intrigues and calculations, no more impetuous pursuit of fame and fortune. All you have is a cup of tea and a handful of books.
