HP: After binding to the strongest wizard development system

Charlie took the potion bottle and shook it curiously. At the same time, he showed a big and bright smile to Till: "Why should I worry about the potion you boiled? Let me show you the effect tomorrow!"

Charlie's heroic look made Tier narrow his eyes with satisfaction. She came over to talk about this matter, said goodbye to him and everyone, and returned to the Ravenclaw table.

As soon as she left, many Gryffindors who had a good relationship with Charlie overwhelmed him, questioning him about what Teal had said to him and what the potion was for.

Bill stood up leisurely, rescued his younger brother, and relied on the double pressure of the senior and top student to successfully get him to sit back in his seat.

But before Charlie could breathe a sigh of relief, Bill lit the table, narrowed his eyes and asked him: "Why is Till looking for you?"

Charlie: ...

***

That night, just as Teal expected, Charlie used his delicate and smooth hands, which were completely different from the skin color above the wrists, to perfectly demonstrate how effective Teal's "hand-protecting potion" was.

The excitement brought by this publicity effect is real. Before Till left the library, many Gryffindor girls came to find him, but most of them were stopped outside the library by the angry Mrs. Pince. .

As the "culprit" who destroyed the peace of the library, Till reluctantly walked out and led the group of girls away under the glare of Mrs. Pince.

When they came to an open space away from the library, everyone asked Thiel about the "Hand Potion" one by one. Thiel also perfectly used his academic master and "supplier" momentum to tell everyone to be quiet. After that, I started my first step in business.

She only has three large bottles of "Hand Protection Potion" left on her body. It is definitely not enough to sell it to only three people. But fortunately, this "Hand Protection Potion" is very effective. It only takes a small amount to get a lot of it. Good results.

A large bottle of "hand protection potion" can be used by at least four people.

Till left one bottle for Mgina and Tonks, and the remaining two large bottles were sold to eight girls on the spot for fifteen silver sickles each.

This price is considered cheap. Not including the cost, Thiel only earns about seven gold galleons, and the cost price of each pot of "hand protection potion" is controlled by Thiel at five gold galleons.

Potion materials are not cheap. Even someone as wealthy as Tyr would have to work hard not to waste any potion materials in order to save consumption this morning.

Till felt that he didn't make much, but among the girls present, not the majority could easily take out fifteen silver coins.

Three gold galleons are already the monthly living expenses for most students. Students with poorer family conditions cannot afford even one gold galleon every month.

So when there were only eight places available, everyone who came for the potion didn't fight enthusiastically.

"Til, will there be more in the future? I want to buy a few bottles for my family to try." A girl who obviously has no shortage of money happily holds a bottle of "hand protection potion" and helps her three A friend advanced Yin Xi Ke.

Apparently, she had become one of Teal's prospective customers. Till answered her with a smile: "Of course, this is just the first time. In the future, my parents will open a potion shop in Hogsmeade Village, which will sell many special potions."

"Hand protection, skin care, hair care, whitening... they will be researched gradually." Till will paint a picture for everyone first. As for when they will be researched, it depends on whether she has enough time.

After Tier finished speaking, the girls surrounding him cheered, but soon became confused again.

Naturally, a few girls chatted happily about buying more, but more girls lowered their heads in confusion or loneliness.

Till took in everyone's reactions and after thinking about it for a moment, she knew the reason. She immediately added: "At present, the formulas of various magic potions will be adjusted, and the prices will also fluctuate up and down."

"But I assure you, whether it is so cheap that it only costs one silver Sickle, or it is so expensive that it costs several gold galleons, the effect of our potions will not be weakened." Thiel worked hard to expand his potential customers. .

She didn't know if the girls listened. Anyway, when everyone left, their moods improved a lot. Several of them even held Till's hand, asking them to apologize as soon as possible.

After watching everyone leave, Till sighed at how busy she would be in the next period of time, but she didn't feel the pressure.

To make money, customers have to have needs. When they have no need for you, no matter how busy you are, it will be in vain.

[Host, what are you going to do? 】The system didn’t bother Teal much today, but it didn’t feel bored either. It spent the whole day arranging Teal’s next tasks.

Just waiting for Till's store to open.

Till returned to the library and smiled obediently at Mrs. Pince, who was looking over. He didn't waste time replying to the system in his mind: "Tomorrow I will go to Hogsmeade Village, buy the shop, and ask someone to find someone." Renovate. 】

[After I come back, I will probably adjust the potion formula again to reduce the cost. ] Tier opened the book and frowned with a headache, [I felt relaxed when I was reading the book, but now that I have actually done it, I realize that there are so many things to consider. 】

[Perhaps the host should consider its main service recipients in the future. ] The system gave Tier serious suggestions, [Just like the group of "customers" you received tonight, they are all attracted by the effect, but some people have money and some have no money. They face You name the price and there will be a different reaction. 】

Thiel told the system without hesitation: [I never planned how expensive the potion would be from the beginning. 】

[I want to make money and expand my industry. Small profits but quick turnover is the way I should go, instead of relying on high fees to only attract rich people and push my shop to the so-called aristocrats who only account for a small number. 】

The system was very satisfied with Thiel's answer and knew that Thiel was someone who could listen to advice. It directly pointed out Thiel's cognitive bias: [In this case, the host should not use the values ​​​​that he has developed since childhood to study costs. , the host may be able to change the perspective and treat the adjustment of the potion cost from another perspective. 】

[You mean, I have to assume that I am poor? ] Thiel understood, [When I think I have no money in my pocket, I will do everything possible to save costs so that I can earn greater benefits with less cost. 】

【Yes! The host is so smart. 】The system simulated the sound of applause, and I really appreciated Thiel's one-click answer.

Because Till has never been short of money, when it comes to selecting potion ingredients, she thinks about using them well and has never thought that some potion ingredients can be completely removed.

In this way, the cost will naturally not be low.

Tier's slightly frowned brow relaxed, feeling more confident about adjusting the potion for tomorrow.

She even "drawn inferences" and when she set out for Hogsmeade the next day, she was already so into the mood that she started bargaining with the owner of the shop she liked.
