After saying that, Aya let go of Silas’s hand and kept the bottle back.
A purification potion was a rank 6 potion that was hard to make. Only rank 6 alchemist or above would be able to make it. Some special alchemists can make it at rank 5 but it was rare.
For Aya, it was easy as long as she had enough materials.
The problem was, the materials were also rare and there were not many of them sold. Whenever there was some, Aya would buy them.
Because the purification potion was very important.
Moreover, a purification potion could only be made by either a rank 6 alchemist or an alchemist with light magic. Because the light magic could replace some of the materials.
Aya is a light magician.
Aside from some materials that still have to exist, she replaced the rest with her own magic. It was more efficient and cost effective.
"I..." Silas wanted to say some words and looked at Aya’s eyes. For some reasons, he felt that he was completely seen through by this student of hers, which was a strange feeling. No one else had ever made him feel really hard to read and kept on interfering with his life.
After a moment, he replied, "I understand."
The person who casted the curse was that b*stard elder. But he couldn’t fight back at all when the few people who faced him were all the higher ups of Wansu City.
It was only now he realized that there were actually more rank 6 magic warriors in Wansu City.
If not because promotion to rank 7 was dangerous, there might be a few more rank 7 magic warriors in Wansu City.
His magic was strong, but he was not willing to expose his trump card.
Moreover, Silas also knew that it was his mother who was in the wrong. Even if she died in the end and Yansu City’s schemes failed, but it would not change the fact. So he didn’t fight back and when he realized what they wanted to do, it was too late.
The curse was placed.
Dark magician could slowly erode the curse and this was what Silas was planning to do. But he couldn’t do it in the open and only did it quietly.
But the process alone would take a long time.
The best way to remove a curse was through purification magic, a high rank light magic spell. And the purification spell was a rank 7 spell.
In other words, only rank 7 light mage could possibly erase the curse.
And curse magic itself could only be learned starting from rank 5 because any lower and the cost of their curses would be their own lifespan. Even if many people were desperate, they still would want to live longer. The lower their mana, the higher the lifespan consumed.
Moreover, lower ranked curse would only take effect when the caster was still alive.
Once they died, their curse would also be erased naturally.
So Silas also thought about killing the caster when there was a chance.
"How much is the purification potion?" Silas asked.
He had never been to the Central Magic City, but he had heard that purification potion could only be made by a rank 6 alchemist. If it was the rare light element alchemist, then they had to be at least rank 5.
It was by no means low.
Aya looked at Silas strangely. "You won’t be able to pay me back even if you work for your entire life."
At least, the current Silas would never be able to pay back so much money. Unless he managed to reach rank 7 and then hunted higher ranked magic beasts, he would never be able to pay back the money.
But thinking about Silas’s talent...
Well, he might be able to reach rank 7 soon.
But even if he reached rank 7, he would not necessarily be able to hunt those rank 7 magic beasts and obtain their magic core.
He knew that he was poor because he spent most of his money for his mother. Now that he didn’t have to take care of his mother anymore, he could collect money for himself.
How could it be possible that he couldn’t pay it back?
As long as he worked hard, it should be possible, right?
"The most commonly used currency for rank 5 or above potions are to use the magic crystal," Aya said slowly. "And magic crystal can only be found in areas with high mana concentration that are heavily protected by rank 6 or above magic beasts or formed by a rank 6 mage through consuming the entire mana to condense it, which would require him or her to rest for a few days to accumulate enough mana again."
"Another method to obtain magic crystal is through purification of magic cores, but not many people know how to purify it. After all, the magic spells used for magic core purification itself can be considered rank 6 magic spell, which is by no means low rank."
"A rank 5 magic potion costs around 1 magic crystal. A rank 6 magic potion costs 5 to 10 magic crystals. And rank 7 magic potions costs 100 magic crystals at the minimum. Magic crystals could also be exchanged with magic cores, but you need rank 7 or above magic cores to exchange for one or even make one from the magic core."
"And if I’m not wrong, the exchange rate is 10 rank 7 magic core for 1 magic crystal. It can be more or less, but it’s definitely very expensive."
Aya looked at Silas with a playful look. "Purification potion is a special rank 6 potion, so it usually costs around 50 to 70 magic crystals. So do you think you can pay it back, Teacher~?"
The last tone was purposely lengthened in a playful manner.
Silas fell into silence.
He looked at Aya with a complicated expression. "Should I pay with my body or my life?"
