After selling all the shaping seeds and fireshell fruits he brought, he got a total of 60 low-level magic crystals, and Aaron spent 10 magic crystals to buy a batch of seedlings again.

Both the Molded Vine and the Shell Tree can only be harvested once, so the ones left on the balcony are useless, and Aaron is going to get them away when he goes back and replace them with a new batch.

"In a month and a half, I earned 50 magic crystals, which is very good, much better than those who take risks to do tasks!

Aaron walked to his treehouse with his things, muttering to himself how much more he could earn than by cultivating these magic plants after learning to refine potions. Gao is for sure, but he doesn't know how much higher, anyway, he has always heard others say that pharmacists are the most lucrative profession.

After returning to his lodgings, Aaron planted a new batch of molded vines and fireshell tree seedlings, and those that had already been harvested were removed and kept useless.

"50 low-level magic crystals, it should be enough to buy the most basic potion knowledge with Wren, I don't know how many purchase materials can be left for testing......" Aaron doesn't even have any basic knowledge of potions now, those materials in the library, only some brief introductions about potions, and no little potion knowledge is recorded, which shows that these knowledge are very strict, unlike other knowledge, at least the most basic knowledge will be free and open.

After planting a new batch of magic plants, Aaron couldn't wait to leave the tree house and hurried to Wren's residence.

"Aaron, aren't you already busy with today's work, why did you run back again?" As soon as he arrived at the door, Bruce just opened the door and walked out: "Seeing that you are so anxious, are you in any trouble?"

"I've been staying in my residence all day, what kind of trouble can I cause! I'm done with today's work, I'm going to go to Mentor Ren to buy paid knowledge. Aaron walked up to Bruce, paused, and replied.

Bruce nodded: "Oh, I see, by the way, what kind of paid knowledge do you want to buy, is the magic crystal enough, not enough for me to add a little to you." ”

"I have enough knowledge of the basic knowledge of pharmacy I want to buy, I have enough magic crystals, thank you for your kindness!" Aaron had taken Bruce's 10 magic crystals before, and of course he was embarrassed to ask him for them again this time, so he naturally refused the other party's kindness.

"You also want to learn pharmacy! Don't you think about it, this thing is very magic-burning crystal, my grandfather asked me to worship under Mr. Wren, just to learn pharmacy with him, it's been almost half a year, I still haven't made much progress, I can only refine the simplest shaping potion!" Bruce sighed. "You know, it has cost me thousands of magic crystals in the past six months, even if you are very talented in this area, you also need a strong economy as a backing, you have to think carefully, don't waste magic crystals and time in vain. ”

Bruce himself was to learn potion refining, so he worshiped under Wren, and there was a grandfather of an official mage as a backing to provide resources, and he spent half a year on it, but his grades were very average, so he knew the difficulties involved.

Bruce knew that Aaron was not like himself, he had a strong financial backing, and when he said this, he also hoped that Aaron would not delay the learning of other knowledge because of this, which was a good intention.

"Thank you for the reminder, I'll pay attention, but I still want to try, if it's too difficult, I'll give up, I won't ......stumble on this," Aaron thanked tactfully.

"Well, since that's the case, then I won't advise you anymore, don't force it. Bruce shook his head helplessly. "Then I'll go first, you go to Teacher Ren to buy pharmacy knowledge. ”

After saying that, Bruce left here in a hurry, not knowing where to go, anyway, every time Aaron saw him leave, he looked like he was in a hurry.

"It took Bruce half a year and thousands of magic crystals to learn to refine one of the basic potions, and looking at this potion is several times more difficult than I imagined......" Looking at Bruce's distant back, Aaron fell into deep thought. "But yes, if it was so easy to become a pharmacist, it wouldn't be the richest profession......

Wren walked out of the real room, entered the living room, and saw Aaron who was waiting: "Aaron, did you have something to do with me?"

Wren had told him not to be interrupted or disturbed when he was in the real room, and when he just came in, Aaron found that Wren was in the real room, so he could only wait in the living room

"Teacher, I'm going to buy you the basics of pharmacy. Aaron stood up and replied with his mouth open.

"Yes, the basic knowledge of pharmacy was originally 50 low-level magic crystals, I can give you a discounted price, 40 will do. Wren frowned when he heard Aaron's intention, and he wanted to persuade him, but then dismissed this thought.

In Wren's impression, Aaron has an excellent memory and a high comprehension ability, and in the past two months, everything that needs help only needs to be reminded once to remember it completely, and he has not made a single mistake.

For some reason, he felt that Aaron might have a certain talent in studying pharmacy, and because of this, he did not dissuade him, but had a kind of anticipation.

Aaron took out a small bag from his bosom, poured out some low-level magic crystals, and counted them carefully: "Teacher, here are 40 low-level magic crystals, you can take them." ”

Wren smiled faintly, took the magic crystal handed by Aaron, and didn't confirm whether the number was correct, so he put it away: "You wait, I'll go to that thing and come to you." With that, he went to a room.

After a while, Wren returned to the living room with an extra crystal ball in his hand, the size of a fist, about the same as the one Gandalf had left for Aaron.

"In this crystal ball, the basic knowledge of pharmacy is recorded, you have to remember, you can only look at the things here twice, and then they will disappear, and after you learn them, you can't share them with others. Before handing it over to Aaron, Wren admonished with a stern expression. "The crystal ball contains shaping potions and nutritional potions, formulas of two basic potions, and then if you don't understand or have doubts about this aspect, you can come to me. ”

"Thank you, teacher, I see!" Aaron took the crystal ball and nodded repeatedly.

Wren looked at Aaron with a happy look on his face and smiled with relief, remembering that when he first came into contact with pharmacy, he was also similar. "Well, if there's nothing else, you can go back, I'm going to go in and continue experimenting......"

"Teacher, I don't have anything else to do, I'll go back now......"

Watching Aaron walk out the door, Wren said to himself, "I hope you can surprise me......"

Before returning to his residence, Aaron first went to the trading area and bought 4 copies of the raw materials for the shaping potion and the nutrition potion, each of which was 1 low-grade magic crystal, a total of 8 of them, and the last 2 were used to buy some equipment for refining potions.

"Washing tablets, analyzing the basic knowledge of pharmaceuticals, establishing a real model, and simulating the refining and outflow ...... of real plastic agents"

"Drop! task establishment, simulation of real yàn in ......"

Aaron sat in his chair and waited for the results of the chip. The safest way is to use the chip to analyze, simulate the real yàn, and get the most secure steps, as well as precautions, so as to maximize the success rate.

Aaron knew very well in his heart that he was not a genius, but relied on the ability of the chip to have his current achievements.

Aaron sat in a chair with his right hand on the table, closed his eyes, his fingers tapped regularly on the table, and time passed bit by bit......

"Drop, the task is completed, ......" Ten minutes passed, and the chip finally responded.

Although it is only a short ten minutes, the chip has been simulated hundreds of times, and a set of more complete and higher success steps have been summarized and analyzed.

The table was filled with test tubes, beakers, utensils, glasses, catheters, and many other equipment, very similar to the equipment needed for chemical practice, and at first Aaron felt very nostalgic for this, remembering some of the practical things he had done in school.

First, the raw materials are simply processed, and then according to the prompts of the chip, some black powder is packed into a test tube, and the bottom of the test tube wall is burned with a flame lamp to heat the black powder.

"The temperature has reached the condition!" Soon the auxiliary prompt of the chip sounded, reminding him that the black powder in the test tube had reached the required temperature.

After receiving the prompt, Aaron hurriedly picked up a straw, sucked a few drops of clear liquid from a vessel, and dropped them into the test tube.

Hiss...... Hiss...... Hiss......

As soon as the liquid touched the high-temperature powder, it immediately hissed, and billowing white smoke filled the test tube.

As the test tube vibrates, the billowing white smoke gradually changes color, transforming the car into light green, followed by the black powder also turning light green, and finally, the green smoke disappears, as if absorbed by the powder.

With this done, Aaron uncovered the tube and continued to use the straw to add the clear liquid from before, this time without any smoke.

However, Aaron continued to use pliers, clamping the test tube and shaking it slowly, and the light green powder inside absorbed the transparent liquid, and the particles became a little larger, but the color did not change at all.

Then Aaron repeated this step more than a dozen times, and the powder in the test tube gradually became larger, and now it can no longer be called powder, but has become a fine crystal particle, gently shaken, hitting the wall of the test tube, making a dangdang sound.
