On the first day after returning to Luoguxiang, Yun Guyuan and Yi Qingqing came to the backyard after breakfast, moved the wood out of the space, and piled it on the open space.

Yun Guyuan went to the tool room and took out all the carpentry tools and started to work. Yi Qingqing stood by to help him move this and that, or wipe his sweat, serve him tea, and from time to time she would wash some fruit, cut it into pieces and feed it to him.

In the summer, the sun is very strong. Even if there are many trees planted in the backyard, they still cannot withstand the long-term exposure to the sun, especially in the few hours near noon.

Yun Guyuan, who was not afraid of heat or sunburn, didn't think it was a big deal, but he was worried that Yi Qingqing couldn't stand it: "Go to the house and rest for a while. You don't have to stay here with me. I don't want you to get too hot."

Yi Qingqing moved a small stool and sat under the shade of the tree next to her. She propped up her chin and looked at him. She shook her head when she heard him say, "It's almost noon. Let's go to the house to stay in the shade this afternoon. You only need to do half a day of carpentry work every day. Take your time and don't tire yourself out."

Yun Guyuan calculated the time required to make the shop items. "I do have quite a bit of time. I might as well schedule the carpentry work in the early morning and evening to avoid the hottest time of the day. I can work for two hours at a time and finish the work in a month."

"Okay!" Yi Qingqing felt that this was better than being busy for half a day at a time. The temperature in the morning and evening was just right, and it was the most comfortable to work: "I'll be with you!"

Yun Guyuan knew that she was insisting on accompanying him, so he thought for a moment and said, "Move the recliner to the shade of the tree tomorrow and lie down while you learn what you want to learn. As long as you are within my sight, it will be fine."

Yi Qingqing couldn't persuade him, so she said, "The Ghost Festival is next month, and this year's offerings haven't been prepared yet. While you work, I'll make paper figurines beside you!"

"Okay," Yun Guyuan said.

From that day on, she would make two large pots of cooling tea every night, and ask Ayuan to put them in the Yintu Guidao to freeze them. Then each of them would take a pot and put them in the space to keep it at a constant temperature so that they could drink it while working.

While Ayuan was working, she would sit under the shade of a tree and fold gold ingots, accompanied by the sound of ding-dong-dong.

Work for two hours in the morning after daybreak and another two hours in the evening before dark.

At other times, the two of them would stay in the study to read and study, or farm in Yi Qingqing's portable space. Their days were fulfilling and comfortable.

About a week later, in the evening, when Ayuan finished making a clothes rack and was about to go home, Yi Qingqing once again sensed the small stall of Yin Yang Pavilion where her family had gone out to wander.

"Ayuan, wait a minute," Yi Qingqing called out to Yun Guyuan who was pulling her to the front yard, "I'm back to my stall."

"Small stall?" Yun Guyuan didn't react for a moment.

"It's just that my Yin Yang Pavilion skill is really too small. It's like two different things from the Yin Yang Pavilion of your Yin Ling. It's more appropriate to call it a small stall," Yi Qingqing explained.

Yun Guyuan understood: "Do you want me to avoid it?"

“No need,” Yi Qingqing shook her head: “I just happen to have something to ask you, let’s take a look together!”

Yun Guyuan then stood quietly beside her without moving.

Yi Qingqing stretched out her hand and waved it in front of her. A small wooden stall with a small roof, three shelves and a dusty surface appeared in front of them.

Yi Qingqing's face was full of question marks. She hadn't seen it for half a year, and she didn't know where this small stall had gone to sell its goods. Why was it all dusty?

She checked the condition of the stall. Fortunately, there was nothing damaged, but it was a little dirty and needed to be wiped clean.

[Your Yin Yang Pavilion sold 1,000 gold ingots and earned 20 units of soul power, 20 incense sticks earned 20 units of soul power, and 5 paper villas earned 10 units of soul power. The current soul power balance is 55. Do you want to withdraw it as sign-in points? ]

Yi Qingqing nodded decisively.

She remembered that she only earned 5 units of soul power from the 500 gold ingots she sold last time, an average of 0.01 units of soul power per gold ingot.

This time I filled up the shelves with 1,000 gold ingots and actually earned 20 soul power. On average, one gold ingot is 0.02 units of soul power, so the price has almost doubled!

On average, one stick of incense costs 1 unit of soul power, and one paper villa costs 2 units of soul power on average.

Judging from the unit price, it seems that selling paper villas is the most cost-effective, followed by incense sticks, and gold ingots are the cheapest. However, in terms of production difficulty and speed, gold ingots are the easiest. With her current hand speed, she can make one gold ingot almost every minute.

The production of incense for worshipping gods and paper-made villas cannot be done quickly at all, as they are both delicate jobs.

Moreover, the incense for offering to gods has to be supplied to the incense hall, so there is simply not much left. It is more profitable to sell these 20 incense sticks than to sell gold ingots. The same goes for the paper villas.

However, the price of the gold ingots was still fluctuating. Yi Qingqing felt that she still had to figure out the reason so that she could earn soul power more efficiently.

Fortunately, she had the idea of ​​comparing prices before. She kept a sample of each of the first and second batches of gold ingots sold, which were made in the same period of time, including incense for worshiping gods and paper villas.

Now there is a ghost messenger in front of me who has seen the super-large Yin-Yang Pavilion and is familiar with the prices in the underworld. Of course I have to ask him!

Yi Qingqing found these things and said, "A Yuan, can you help me see what the price of these things would be if I bought them with soul power at the Yin Yang Pavilion that has a cooperation with the underworld?"

Yun Guyuan took a closer look and pointed at the first batch of gold ingots: "100 such gold ingots are worth about 10,000 ghost money or 1 unit of soul power or 0.1 unit of Yin De."

"This one is of better quality. 50 of them are worth 10,000 ghost money or 1 unit of soul power or 0.1 unit of good karma." He pointed to the gold ingot in the second batch.

"I've looked into the incense sticks before, and the lowest quality one costs five thousand ghost money. The one you made should be sold for around ten thousand ghost money. As for the paper villa, I'm not sure. I'll go and take a look at it for you tonight and then tell you." Yun Guyuan said.

“No, no,” Yi Qingqing waved her hand, “That’s all you need to know. Is the selling price more related to the quality of the item?”

The pricing of the Yin-Yang Pavilion that cooperates with the underworld is almost the same as her small stall, except that her small stall can only earn soul power, not ghost money and good deeds.

One of the two gold ingots was made when her paper-making skill just reached level 4, and the other was made when her paper-making skill was about 30% advanced to level 4. The former is definitely not as good as the latter, so it is normal that it is cheaper.
