The first page only took an hour, and the second page was an hour and a half, and the longer it took to get to the back, because each page contained more and more information, and some of them contained tens of thousands of potion information, even if there was a cheating of the original main god core, it would take time.

Especially the thirty-first page, which is full of some legendary potions, some legendary potions in the wizarding world, some of them don't know if they are true, they all have magical effects, and the content in it is amazing, up to a million kinds, plus the variables of guessing, the content is even more terrifying, the content of this page alone is more than the previous thirty pages combined, and this page alone took him a week to imprint in his soul.

After reading everything, Ye Qing fell asleep directly on the bed, too tired.

After reading all the contents, his potions science has reached its peak in terms of potions understanding, and it is estimated that the mentor Ms. Crystal is not as strong as him in this regard.

"How much have you watched?"

When returning the book, Ms. Crystal gently stroked the crystal on the page and asked casually.

He thought for a moment and said:

"I read thirty pages."

She turned her head and fixed her eyes on him, with no expression on her face, but he was sure that she was astonished in her heart, but only surprise, not horror, and after a while she put away the large book, and said to him:

"From now on, you're going to spend three hours serving me every other day until you become an official wizard."

"Yes, teacher."

He followed her and came to her lab again.

This time was different from before, after reading the entire book, he could recognize all the various potions here, and he also clearly knew the habits and medicinal properties of potions, as well as how to cultivate and pick them.

The mentor, Ms. Crystal, was busy standing in front of the laboratory table, and he was watching carefully from the side, when suddenly she said the name of a potion:

"Two Devil May Cry flowers in the second row of the fifth column!"

Ye Qing immediately turned around and came to the other side of the laboratory, there were more than a dozen rows of long shelves leading straight to the ceiling, each shelf had several layers, and they were filled with all kinds of potions, all of which had been preliminarily processed.

Devil May Cry is a plant with black petals, the flowers are open, and the inside is a layer of black like oil, I don't know if it's pollen or what, in the center of the flower, there is a greasy human figure twisting, like a ghost.

Reaching out and grasping the root of the Devil May Cry flower, the potion let out a scream, and several large leaves on both sides rolled up, and the serrated edges of the leaves snapped together like teeth to bite his hand, but the strength was not enough to bite through his skin.

Grabbing two potions that were constantly struggling and screaming, she reached out and pointed, and the two potions flew towards her, and the potions seemed to feel their fate in mid-air, struggling more fiercely, and the screams became sharper, the crystal lady was not affected at all, and with a wave of her hand, the two potions fell in a crystal basin like a basin in front of her.

The pot was half a basin of transparent liquid, viscous like jelly, as soon as the potion fell into the jelly, it began to melt, and soon the whole plant merged into it, and a scream stopped, and the whole pot of transparent liquid turned black.

Next, she instructed Ye Qing to keep taking strange potions, a green mushroom bouncing like an umbrella, a large cotton flower with a light rootless flower, a death fruit that is completely a skull, etc., most of which are quite dangerous, and mortals may be eaten by the potion when they encounter it.

It took Lady Crystal nearly an hour to fuse the potions into them, then condense them into an extremely thick original potion, and then use some kind of magic to purify the dregs and refine them into a bottle as clear as the blue sky.

These potions have different colors, and the colors of the original potions fused together are also cloudy, but in the end, the finished potions are so beautiful, Ye Qing guessed that the most important thing is to purify the residue of the medicine in the back.

It's a pity that he can't do this spell, this is a spell dedicated to potions, if it is a technique, he can simulate, but the spell must be learned by hand, and it is impossible to see it just by looking at it.

Fortunately, he could learn this spell, and he would be qualified to learn it when he advanced to advanced pharmacy.

This spell is a potions spell unique to Lady Crystal, in fact, the pharmacists of each school have different potions spells, and the success rate of refining potions is not the same for different spells, and the aspects of expertise are also different, Ye Qing can learn this spell from Lady Crystal, but if he wants to go further in this area, he must create a potions spell that suits him.

In the following time, in addition to helping Ms. Crystal every other day, Ye Qing also tried to mix potions in his laboratory.

He himself has a foundation in pharmacy, and his level is not high, he is only a beginner in pharmacy, which is not much different from the potions in this world, and he only needs to make a slight adjustment to adapt.

The crystal tower belongs to one of the five towers of the Five Ring Tower, the supply of various materials has always been a priority, and there will never be a shortage of materials for potions, Ye Qing will spend one magic stone per month and the two magic stones he earned before on exchanging potion materials.

Although the three magic stones were not a lot, if he only changed the most basic materials, he could change a lot, which was enough for him to use for a long time.

Telling Miss Keykey that she needed to retreat, Ye Qing locked herself in the laboratory and began to try to concoct the potions of this world.

The first potion is called the hemostat, which is supposed to be the simplest potion in the wizarding world, and the first time always starts with the simplest.

The hemostatic agent has more in common with the life medicine he once concocted, both are therapeutic agents, but the healing drugs are all-round treatments, and the hemostatic agents are better at recovering from body injuries.

According to the potion blending method in this world, it is slightly different from his previous blending method, because the potion here is extraordinarily thick, and it is not suitable to use a test tube beaker or the like, most of them use a larger container, and finally directly use spells to purify the last step.

He can do the simplest spells, and he will have one when he is learning elementary apothecary.

After carefully studying the method of preparing hemostatic agents several times, Ye Qing began to prepare hemostatic agents.

This didn't bother him, after all, he was a man who even blended perfect-level life elixirs, although the world was different, some rules were still interoperable, and it would never be a problem to mix the simplest potions.

After only two failures, he found the trick, the third time in one go, and then ten consecutive attempts all succeeded, and the quality was better than the first, and by the ninth time, the perfect quality hemostatic agent had been prepared.

"Interesting!"

Holding a small transparent glass bottle in his hand, it was a viscous red liquid, and inside was a hemostatic agent of perfect quality, which he used in a small glass bottle, so it looked like a life potion.

The effect of this hemostatic agent is even more magical than the secondary life potion he once concocted, it can be used both inside and outside, it can restore three hundred health points at a time when taken internally, and ordinary wounds can be healed immediately when used externally, including muscle lacerations, as long as it does not hurt bones, muscle injuries can be smeared with this viscous red liquid.

The hemostatic agent is a hemostatic ointment, and the formula is the same, but the study of pharmacy is deeper, because it needs to be further purified, and the spells of primary pharmacy cannot be purified to that extent.

He only looked at this once and didn't continue, but changed the potion and started trying.

This potion is called a fire potion, and it is a combat potion that explodes when thrown out, gushing out a large amount of flames and burning, which is equivalent to an incendiary bomb, and is a type of combat potions.

In fact, he wanted to try the body refining elixir, but unfortunately this elixir was too demanding, and it would only be involved in at least advanced pharmacy, and his current level was not enough.

In the next time, in addition to being an assistant to Ms. Crystal, Ye Qing tried to concoct potions by himself, and all the potions he concocted were sold in exchange for gold coins to maintain the cost of pharmacy. These are the most basic potions, and it is impossible to exchange them for magic stones, only gold coins.

It's just that this kind of days only lasted less than a month and had to be stopped, for no other reason, mainly because it was discovered.

On this day, he went to work as an assistant to Lady Crystal as usual, and before the experiment began, she suddenly took out a bottle of potion and asked him:

"This is the potion you've been mixing and selling all this time?"

In her hand is a bottle of a type of frost potion, which is one of the several elixirs that Ye Qing has prepared in this month, and it will explode when thrown out, and an extremely cold aura gushes out of it, which can freeze a range of about ten meters in diameter, and can cause three hundred points of damage to the target, the power is not as great as the flame potion, but it is better than having a freezing effect.

There was no need to hide it in front of Lady Crystal, and there was no way to hide it, he directly admitted:

"Yes."

"Don't sell it outside in the future, sell it inside the tower, and buy as much tower as you want."

Lady Crystal didn't waste much time here, and with a casual remark, she put aside his potion and said to him:

"You have a very high talent in potions, starting tomorrow, take an extra hour to study potions with me, and the tower will buy your potions at half price, do you have any opinions?"

"Nope!"

Ye Qing responded decisively.

Don't say that he has no opinion, he can't say if he has an opinion, and this is still a good thing, the only primary potion he is preparing now is worth a few dollars, and learning advanced potion knowledge from her is a sky-high price, you must know that the real potions light tuition is thousands of magic stones, and he doesn't have that money.

Three months later.

In the early morning, in a forest more than 100 kilometers away from the Fifth Ring Tower, a group of gray-robed people walked along the path of the forest, carrying weapons such as swords and longbows, and occasionally a few people held short staffs.

Among them, a particularly tall gray-robed man walking in the center of the team held a delicate staff in his hand, walking in the crowd with a calm face, his mouth kept opening and closing, he didn't know what he was talking about, and next to him was a teammate who kept looking around with a vigilant face.
