A new day began, and first thing in the morning, Drew passed on the tradition of evening self-study to Joseph.
Joseph's eyes lit up; yes, this was a wonderful idea.
During the day, the teacher would impart knowledge, and in the evening, the students would consolidate what they had learned, allowing them to master the material thoroughly.
Furthermore, studying together in the evening would allow them to learn from and verify each other's work, greatly increasing their study efficiency.
Joseph felt an itch he couldn't scratch; he was so distracted thinking about this during class that he didn't even understand the lecture content.
As soon as class ended, Joseph, acting as the class monitor, immediately organized the students to discuss the matter. The students were quite interested and decided to start evening self-study that very night.
Ever since evening self-study was implemented, the pace of Drew's lectures accelerated significantly. During the day, Drew only needed to explain the curriculum clearly and provide brief clarifications. The rest was left for the students to resolve on their own.
Consequently, Drew's lecture time was greatly shortened, and the amount of knowledge he could teach in a single day increased accordingly.
Thus, in less than a month, Drew had finished teaching the entire curriculum.
Once all the courses were finished, there was nothing left for Drew to do. The rest was up to the students to consolidate; Drew only needed to set questions and give them tests.
In this way, Drew had a large amount of time to attend to his own affairs.
Drew spent a few days creating a massive pile of questions, compiled them into a question bank, handed it to Joseph, and stopped worrying about it.
All management matters were left to Joseph to handle on his own. Drew felt it was time to start researching alchemy.
Previously, because of this study group, he hadn't updated his stock with new potions for several months, and even the mayor had expressed his dissatisfaction.
For the past half-year, the shop had only been selling Antidote Potion and Shadow Potion.
However, there was one piece of good news: the sales of high-quality Antidote Potion had finally opened up.
The mayor had found a major buyer in the nearby large city of Gold-Gleam Town.
They were now selling high-quality Antidote Potion in bulk on a monthly basis.
Now that Drew and the mayor had money, Drew wanted to develop new potions again.
The potion Drew wanted to research this time was a Life Potion—wait, was that a typo?
Wasn't it supposed to be Healing Potion?
It really wasn't a typo; he was indeed researching Cure Potion.
Karen knew how to make Healing Potion, which meant Drew knew how to make it too; it was very simple.
But Cure Potion was not simple; one shouldn't underestimate the difference a single word could make.
Healing Potion contained a great deal of magic power, which ordinary people could not use.
However, the magic power contained in Cure Potion was very low, and naturally, its effects were much smaller than those of Healing Potion.
But the key was that ordinary people could use it.
This was the crucial point. Developing a healing-type potion that ordinary people could use would spare them the awkward situation of having to seek out a priest the moment they suffered a serious injury.
After all, priests capable of using healing spells were all professionals. Moreover, they were rare divine-class professionals.
It was very difficult for ordinary people to afford the price of hiring them.
If there were a common Cure Potion, they could obtain effective treatment for a relatively small amount of money.
Many ordinary people would be willing to pay that, and while finding a priest might not be possible on short notice, buying a bottle of Cure Potion to keep on hand was something most could manage.
It was convenient, fast, and efficient, but were there any Cure Potion on the market? No.
The Alchemist Association had even issued a bounty, offering a high reward to any alchemist who could produce a formula for Cure Potion.
But no one had ever completed this task, and the formula for Cure Potion had never appeared.
Not even the ancient formulas contained Cure Potion.
This was because there were no ordinary people in the ancient era; the physiques of the common folk among the ancient races were extremely high, allowing them to use Healing Potion.
But the humans appearing now had physiques that could not handle it. Now, Drew wanted to solve this historical problem.
The reason Healing Potion could not be used by ordinary people was that the magic power was too concentrated for their bodies to withstand. The way to solve the problem was to reduce the concentration of magic power.
But the reality was certainly not that simple, or else this formula would have been solved long ago.
Drew searched through Karen's memories. Karen had a very deep impression of the main ingredient of Healing Potion, the Life Flower.
Such a situation where properties were completely reversed was very rare.
So, would it be feasible to change to a different main ingredient, one with lower magic power?
Or perhaps replace it with an ingredient containing natural or holy light attributes?
After all, both natural and holy light attributes possessed healing effects.
Was there any material that contained natural or holy light attributes?
Drew consulted some materials; this was a book on common and basic alchemical materials that he had borrowed from the Alchemist Association branch using Joseph's identity.
Drew did manage to find some information about natural and holy light materials in the book. Holy light materials were still very overbearing; perhaps they could be controlled when cast by clergy, but they didn't seem that overbearing yet.
However, if one were to use holy light materials for alchemy, the materials would be extremely difficult to control.
One could imagine that if holy light materials were used to make Cure Potion, it would be even more unbearable for ordinary people.
It would be better to just use a Healing Potion directly. This path clearly won't work.
Materials with natural attributes are not as overbearing; in fact, they are the best materials for crafting Cure Potion and potions.
The healing effect of natural attributes is the gentlest, but the onset time is extremely slow.
But that is not the point; the point is that materials with natural attributes are all extremely precious.
Compared to the main material of Healing Potion, Life Flower, materials with natural attributes are all very expensive.
Therefore, using materials with natural attributes to craft Cure Potion is not impossible, but it is simply not cost-effective.
If it were crafted specifically for a certain person, it would be one thing, but to develop a formula, it would require multiple experiments.
Because the raw materials are precious and cannot be widely popularized, it is truly somewhat unnecessary.
It seems this path is also difficult to tread; he must think of other methods. In the absence of substitute materials, Drew could only look for a solution starting from the original Healing Potion.
First, Drew observed the particle state of the finished Healing Potion at a microscopic level.
Then, he diluted the Healing Potion with water and continued his observation. He discovered that the liquid of the original Healing Potion did not dilute in water at a microscopic level, but instead gathered together in small clusters.
In other words, the Healing Potion liquid and water are immiscible, so when an ordinary person drinks such a potion, it is actually no different from drinking a small amount of Healing Potion.
Ordinary people with weak constitutions still cannot withstand the power of the liquid. This method would not work, though Drew never expected it to succeed; after all, if it were that simple, anyone could do it.
Drew used this method to determine the reason for failure; after all, failure is the mother of success, and summarizing experience is always good. Perhaps it could serve as a reference for the correct method.
Since the liquid cannot dissolve in water, could it perhaps dissolve in other solutions?
Could it be that as long as he finds such a solvent, this difficult problem can be solved?
Although Drew did not believe the problem would be solved so easily, it was always good to try, as failure is also a step toward success.
The time that followed was spent finding suitable liquids to conduct experiments.
