With this common item trading card, it doesn't mean everything is fine for her.

Each trading card can only be used to trade a single item. If you want to exchange for something else, you have to buy another trading card, which costs a huge amount of 5 sign-in points each time.

Moreover, these 5 check-in points are not used to buy things, but only to buy a purchasing qualification.

After buying the card, you still have to pay the price later, and the prices will fluctuate over time, leaving no loopholes for people to exploit. It is probably impossible to take advantage of it.

If everything can be exchanged, it would be more cost-effective, but the word "ordinary" has already limited the scope of its transaction.

So after thinking about it carefully, she realized that now she could only use it to buy some paper-making materials that she couldn't get herself.

There are many different kinds of paper-made materials. If she really had to use trading cards to buy them all, she wouldn’t have enough even if she emptied her check-in points.

Some substitutes that can be bought on the market or made by yourself are not considered.

In fact, what is most needed is gold and silver paper.

If she can't buy yellow paper, she can find a way to make some herself. The materials she needs can be grown in her portable space, and tools can be obtained using the tool components of the skin card, and they are very cheap.

Gold and silver ingots must be folded with gold and silver paper, and the quality must be good.

But although both gold paper and silver paper can be used to fold gold ingots, they are also two different types of paper. If you want both, you have to use two trading cards, which is not worth it.

They are all gold ingots anyway, and the way to fold them is the same, but silver ingots require less effort. It is better to just buy gold paper, fold more gold ingots and burn them to make them more valuable.

After thinking it over, she chose to exchange the trading card, and then a new product page appeared in the product column of the system store. Compared with the product pages of those magical items, this product page was gray and looked a bit shabby and faded.

【Gold Paper】

[Introduction: High-quality gold paper handmade by veteran craftsmen]

[Price: 10,000 ghost money/knife (burn to No. 444, Yinshui Lane, must be done in the main world, the fastest delivery time is mid-July, there may be delays at other times, please indicate the detailed delivery address with the payment, the transaction is protected by the system, safe and worry-free)]

[Quantity: Unlimited]

Yi Qingqing looked at the word "burn" and fell into deep thought.

When I bought things in the system store before, I paid with sign-in points, which were collected directly by the system. This time, I have to spend money myself.

Who needs to be burned? Of course, the dead.

Is she doing business with ghosts? Ghosts can make gold paper and sell it themselves? There are too many businesses in the underworld!

Never mind, there is a system to back her up, she can just give it a try when the time comes.

However, Yi Qingqing didn't care much about the price of each of the ten thousand ghost money. As a paper-folding craftsman who could fold gold ingots, ghost money was nothing to her.

I just don't know how much one gold ingot is worth in ghost money, but when the time comes, I can burn some finished gold ingots and see how much gold paper I can get in exchange for it.

However, paper cannot be burned in the portable space, it still has to be burned outside. Burning it in the portable space is in vain and it will not reach the hands of the owner.

Everything can only be planned after she gets the courtyard house.

It just so happens that it says that delivery will be fastest during the 15th day of July. At that time, just take out a basket of gold ingots for sacrifice and burn them at No. 444 Yinshui Lane.

It was not yet her usual bedtime, so she ran to take a look at the two courses that had just been unlocked today.

【Cooking Skills Teaching Course】

[Zhu Dashan (Level 2 84%)]

[Wen Family Cuisine (Level 5 87%)]

[Royal Chef (Level 5 90%)] (New)

【TCM Skills Teaching Course】

[Yiqi (Level 5 80%)]

[Imperial Physician (Level 5 90%)] (New)

The level of the Imperial Chef’s course is slightly higher than that of Master Wen, and the Imperial Physician’s course is slightly higher than that of Master Yi.

Both are a collection of knowledge from a group of people, not specific people who have ever existed.

She first entered the royal chef's skill teaching mode.

The royal chef introduced his specialties and talked for a long time without stopping. In a nutshell, he knows everything.

Not only can they cook the complicated and luxurious palace dishes, but they can also cook local folk cuisine. They are also familiar with snacks and preserves. They can cook all kinds of food, but they are best at palace dishes.

Yi Qingqing had no interest in learning those palace dishes that were difficult to make in real life, but she was very interested in eating them.

I ordered a full banquet right away. It didn't take up any space in my stomach, so I just wanted to taste the food.

Now she feels that this function of the cooking skills teaching mode is very good. When tasting delicious food, it is good enough to be able to taste the flavor. The feeling of fullness is not important. In the future, this will be a magic weapon that allows you to eat without gaining weight.

Not only did she eat the legendary Manchu-Han banquet, she also tried all the delicacies from land and sea that only the nobles in the palace of all dynasties could enjoy. It was extremely extravagant.

Because of illness in the previous life, I could only look at many things but not eat them, so my obsession with food was largely cured by this super meal.

Just for this, she felt that the 5 check-in points were worth it.

After tasting them, Yi Qingqing picked out some things that she really liked and had no shortage of ingredients, and planned to learn how to make them in real life, mainly pastries, candied fruits, and fruit wine.

After learning these, the fruits in her portable space that seem out of season outside can also be made into finished products and sold out.

Many of the sweets can be fed to Ayuan to change his taste. During this period of time, he has been working hard to accompany me running around and has been to so many places. He has worked hard.

She has no intention of learning how to cook those expensive dishes that are delicious but require too much ingredients. When she wants to eat, she can just go into the skill teaching mode and eat as much as she wants. It can satisfy her cravings, except that it won't fill her stomach.

Yi Qingqing chose to learn the imperial chef's cooking skills selectively, but she paid much more attention to the imperial physician's medical skills.

Even though she had learned many things from Master Yi, it did not stop her from learning them again from the imperial physician to verify them.

When it comes to medical skills, I never worry about learning too much.

The more solid and comprehensive your learning, the more secure you will feel.

After sorting out the two new courses and planning her study schedule and time arrangements, Yi Qingqing returned to the dormitory to rest.

Several important things were accomplished today. The paper-making materials were found, and all the sign-in locations in the Forbidden City that she had ideas for were also sorted out. Now she basically had nothing to worry about.

Basically, until the housing purchase policy was relaxed and she received her own courtyard house, she had no urgent need to sign in.

It's a good time to accumulate check-in points and take a break on the weekend. There have been a lot of activities in the past few weekends, and I'm tired and spend a lot of money.

With nothing on my mind, I naturally slept very peacefully at this moment.
