"A month or so?" Just before, Goya subconsciously regarded the potions he had taken as an instant magic. In her opinion, only the magic in the stories that she had dreamed of when she was young might have such a magical effect. Hearing Tang Bai say that it could only last for a month, Goya's delicate and charming face couldn't help but show a little loss, because this seemed to be different from the conjecture in her heart.

"It can last for at least a month, and the length of time the effect lasts varies depending on the person's constitution." Tang Bai patiently explained to Goya. If it is aided by other potions with specific effects, the effect will last and last longer. But now, Tang Bai doesn't need to take them all out in one go.

"What are you going to do about the price?" Ding Churou on the side looked at Tang Bai with some embarrassment. Hearing this, Goya also restrained the loss in his heart, and waited for Tang Bai's answer with Ding Churou. She was also curious about what kind of price her young boss would set for such a magical potion.

If the price is too high, although the effect of these drugs is extremely significant and amazing, the high threshold is undoubtedly equivalent to giving up a large proportion of female customers. After all, the effects of this agent are not once and for all, or for years without worrying about its failure and rebound.

The one-month timeliness is too short and the price is too high, so there will definitely be many customers who choose other maintenance methods.

Goya naturally hoped that the price of these magic potions would not be too high, and it would be better if they could be within a reasonable range of what she could bear. Not only will she be able to afford it, but she can even make a bold guess that these potions will attract enough attention that the people who use them will become their most loyal customers.

But what made Goya nervous and uncertain was that she didn't know what the cost value of these magic potions was, which even Ding Churou, who had calmed down, couldn't be sure in her heart.

After Ding Churou sent back to the family those truth-spitting elixirs and recovery potions that he had traded with Tang Bai before, the entire family had spent considerable effort and did not analyze the ingredients in them, but they definitely contained some herb ingredients that could not be identified at present, which was undoubted. Many people in the family attribute the source of these ingredients to the crevices.

Ding Churou couldn't be sure if there would still be these herbs from the cracks among these beauty potions and body shaping agents. What she couldn't be sure of was how many of these herbs from the cracks Tang Bai had in his hands, and how long could the amount of these herbs in his hands last?

If the amount of these herbs from the cracks was limited and non-renewable, Ding Churou would rather Tang Bai sell all these herbs to the Ding family and make them into the potions that the Ding family needs, so that they can have their due effect rather than wasting them on ordinary people.

"It is impossible to distribute goods on a large scale in the early stage, so a threshold must be set. You may temporarily establish a membership system where only the highest level of membership will be eligible to use these potions. The membership fee and threshold for this level can be set higher at the beginning. As for the pricing of these potions, there is no need to set them too high, you can negotiate them. Tang Bai waved his hand.

Beauty potions and body resizers, which are created deliberately for the beauty of witches, are not very expensive, and there is no difficulty in cultivating the herbs needed to make them. As long as there is enough cultivation land in the Harry Potter world, Tang Bai will be able to minimize the cost of production.

In some ways, magic is much more efficient than technology.

Even if Ding Churou and Goya set the price of these medicines to be the same as some first-line brand cosmetics, Tang Bai would have a lot of profits.

For Tang Bai, his original intention of buying this club was just to provide a cover for his future source of funds, so that his parents and others could feel at ease, and by the way, he would establish some of his social connections.

Ding Churou glanced at Goya, reached out and grabbed Tang Bai's sleeve, and took him away. Looking at Ding Churou, who wanted to speak and stopped, although Tang Bai was a little suspicious in his heart, he didn't resist, and let her pull him for a while.

Seeing the appearance of Ding Churou and Tang Bai, Goya on the side also stayed in place with great interest.

"Do the ingredients used to make these potions overlap with the ones we traded last time?" Ding Churou was sure where the two of them were standing, and after Goya, who was not far away, couldn't hear their words, she stopped and looked at Tang Bai and asked softly.

Hearing this, Tang Bai glanced at Ding Churou, whose expression had become a little serious, and in a blink of an eye, he deduced the inner meaning she wanted to express in her words. "Don't worry, the herbs used to make these potions are not the same as the herbs used to make restorative and truth-spitting elixirs. You don't need to worry about making these potions, which will weaken the number of potions I trade with your Ding family. Tang Bai explained.

Ding Churou also breathed a sigh of relief when she heard this, the importance of the restorer to the Ding family is self-evident now, whether it is her or the Ding family behind her, they will definitely not want to damage the quantity of the restorer because of this.

……

Night.

In front of an empty railroad track, a train roared from a distance, sliding to a standstill as it approached Tang Bai.

Tang Bai held the gold galleons and Aztec gold coins in the palm of his hand, and stepped into the car door, and when the door closed, the familiar female voice also sounded in Tang Bai's ears:

"Please select the currency you want to use to pay for your trip."

"Gold Aztec coins." Tang Bai replied softly.

"With this coin, you will enter the period of the sixteenth-eighteenth centuries. You can also use this coin instead of a gold Galleon to enter the world of Harry Potter. A melodious female voice echoed clearly in the carriage: "If you want to enter the time period between the 16th and 18th centuries, please enter the Harry Potter world first, and then enter the Harry Potter world transfer station." During this time, you will consume one gold Galleon, and one Aztec gold coin. ”

"In other words, I can't use Aztec gold coins directly from the real world to enter the sixteenth-eighteenth century?" Tang Bai frowned, he couldn't determine the specific time of the Caribbean pirates in his memory, but he also knew that it was around the seventeenth century.

For Tang Bai's question, the inexplicable existence in the carriage gave an affirmative answer.

"Please select the time you need to enter!" The female voice urged.

"Harry Potter." Tang Bai took a deep breath and exhaled.
