Roy and Genosis didn't sleep because they waited all night for Black, so they slept until lunchtime in the morning and didn't get up until lunchtime.

Peter woke them up for lunch.

Peter looked at the four children who were busy eating lunch, and then asked, "Roy, I'll show you an interesting book later, you'll love it." I found a book in the library today that is perfect for you. ”

Roy was stunned and said, "Then we'll have to finish lunch." ”

After lunch, Peter searched for a while in the library on the first floor, and then found a book.

""Introduction to the Alchemist?" Roy looked at it and was stunned again: "What is this?"

Peter said: "This is a chemical synthesis book based on alchemy. ”

Afterwards, Peter laughed and said, "Actually, I am very interested in alchemy, but unfortunately I don't know how to use thunder element magic. ”

"The essence of alchemy is thunder elemental magic. With the exception of metathesis reactions, the essence of most chemical reactions is the transfer of electrons between microscopic particles. Although alchemy is based on chemistry, most of the time, it is the reverse process of chemical reactions. Alchemy is nothing more than the use of thunder and lightning to do the reverse reaction of some chemical reaction that is not reversible under normal circumstances......" Roy shook his head helplessly.

"I don't understand what you're talking about. Peter shook his head and said, "But what is written in this book has something to do with your cultivation, he said that alchemy can make some potions that can increase the speed of cultivation to build a foundation and strengthen the foundation of Peiyuan, and can also make some ointments that can repair wounds, think about it, it's pretty good for you." ”

Roy said embarrassedly, "I know all of this, and besides, I have better textbooks here." ”

Then Roy took out several heavy books in his Void Ring.

"Basic Organic Refining Reactions", "Introduction to Inorganic Alchemy Reactions", "Practical Application of Physical Chemistry in Alchemy", "Alchemy of Biological Agents", ......

In these books, alchemy reactions are generally used to refer to alchemical reactions. Originally, alchemy was simply a technique for smelting inorganic metals, but as people studied chemistry further, alchemy also shone brightly. And alchemy is an improved alchemy of organic chemistry, if I remember correctly, alchemy is a first-level discipline, and alchemy is a second-level or third-level discipline. Roy introduced Peter.

As for the classification of subjects, Peter knew about it, but he didn't bother to bother. What Roy means is that alchemy is a sub-discipline of alchemy.

"Then I don't usually see you practicing alchemy, or alchemy?" Peter was stunned, seeing so many strange books, if he didn't know thunder elemental magic, he might have copied Roy's books into his library. Peter's thirst for knowledge was almost endless.

Roy said helplessly: "Cultivate alchemy...... Oh no, cultivating alchemy takes a lot of equipment and time, and the equipment also costs money. ”

Peter asked strangely, "Don't you still have a lot of money?" Roy said embarrassedly: "Money is actually an excuse, mainly because there is no space for instruments." Also, there doesn't seem to be enough equipment to buy in the vicinity. ”

Peter pondered for a while, and said, "I can inquire about the instrument, but it would be a waste not to learn such a good technique, think about it, if you can make a lot of healing potions, even if you use them yourself, it is better than going to other people's pharmacies to buy medicines." ”

Roy nodded, and said helplessly: "I haven't thought about refining medicine before, but think about it, in fact, refining medicine is more useful than simple alchemy." So, Uncle Peter, if you can find the instrument I need, you'll be fine. ”

Roy was a good alchemist, but he never used alchemy in alchemy. Using alchemy to refine medicine is far more complicated than pure alchemy, because it is the complex field of organic chemistry and biochemistry.

In fact, it is a new science, and many of Roy's books were written by the same person. But the content is very reliable, because when Roy was in the Benlei Empire, Roy had seen his father refine a lot of alchemist products with very good results. Even Roy's father, Frey, was impressed with the authors of these books.

It seems that Peter still has a network here, and in less than two days, Peter bought back a bunch of glass instruments according to Roy's request. All sorts of strange flasks, test tubes, Roy asked for a room on the third floor of this house.

The normal plan is to exercise and meditate every morning, take on relatively simple mercenary tasks in the afternoon, and go to the gladiatorial arena to participate in a gladiatorial fight in the evening.

Now Roy's afternoon time had become his alchemist's cultivation time.

The alchemists called the materials they used medicinal herbs, which were usually plants, but could also be some messy things. Roy went to the herb store and bought hundreds of gold coins of medicinal herbs, not knowing if it was enough for him to practice for a month. Of course, these medicinal materials are mentioned in one of the prescriptions in the "Introduction to the Alchemist". But these materials are very rare,

Bone water. As its name suggests, the medicine is a potion for the treatment of bone injuries, which has the functions of invigorating blood and dissipating stasis, reducing swelling and relieving pain. It is considered the lowest level of healing medicine, because it has no hemostatic effect. There are not many materials used, such as crust insects, hard bone vines, bone sand chrysanthemums, and I have never heard of the names, and they are obviously some uncommon things.

The earth shell insects were dead when they were taken out of the herb shop, otherwise the scene of flying all over the sky, Roy would have goosebumps all over his body when he thought about it. These small bugs are small, the size of a grain of rice.

The mortar is used for grinding, such as this small bug, which needs to be grinded.

However, while Roy was grinding, he was wondering: what the hell is going on with Blake. Strictly speaking, it's the Duchy Alice of the Duchy of Stardust. He is currently the only one of the five in Peter's Library who knows what Blake and Alice are. But Roy couldn't figure out why this was happening.

The reason why Roy couldn't figure it out was very simple, first, Roy, Blake, Genosis, and Elusa didn't know that Peter was the vice president of Cyruster College. Second, Roy didn't know that Peter secretly went to protect the short and beat up other people's families. If Roy knew, then it would have been clear at once: Alice was trying to get close to the Duchy of Stardust and Celester Academy.

Can't figure it out.

But after thinking about it for a long time, the bugs were all ground into powder.

Roy shook his head helplessly, now what he was afraid of was that it would be difficult to deal with the matter of Blake and Alice if it was discovered by the City Lord's Mansion of Demon Cloud City. Roy has seen the most of these things and thinks the farthest. Although Genesys had wisdom, Genesis's wisdom was often limited by his limited knowledge. Of course, now that Blake has decided to break with Alice, that's the best thing to do.

The insects are ground into powder, mainly for the purpose of the shells of the worms, because these shells contain substances that can accelerate bone recovery. The hard bone vine also needs to be ground into powder, but it is too hard, and the mortar is not convenient to do.

Roy wiped his palm, and on the table next to him, there was an alchemy array, and this one was also called the decomposition array. Roy put several bony vines in it. This one alchemy array is used for decomposition, and synthesis requires another formation.

The magic array is an auxiliary means for magicians, and the essence of the alchemy array is nothing more than thunder element magic, so it is a reason. Roy slowly pressed his hands to the edge of the alchemy array, and then his spiritual power soaked into the formation.

Slowly, the thunder elements in the room slowly condensed into the alchemy array, and some lightning visible to the naked eye danced in the formation.

Then, Roy used his spiritual power to put the condensed thunder element into those hard bone vines in the center of the alchemy array.

Alchemy can be fused and of course disintegrated.

It's a pity that Roy controlled too many thunder elements, and after a while, the hard bone vine in the center of the alchemy array was scorched due to the large amount of thunder elements introduced, that is, it lost its medicinal effect.

"Hmm......" Roy shook his head helplessly at the smell of burnt vines, because Blake's affairs made him unable to figure it out and became irritable.

"If you can't figure it out, you don't want to. After Roy muttered to himself, he swept the scrapped bony vine into the trash can on the side, took out the new bony vine again, and decomposed it.

Roy failed three times before he managed to break down a batch of bony vines.

It is not difficult to deal with the bone sand chrysanthemum, and it can be crushed with a mortar.

Of course, this is only the first step in the refining of medicines, the pretreatment of materials.

After it has become a powder, it can proceed to the next step: alchemy and synthesis.

This step is very complicated, it is to use spiritual power to drive the thunder element, and the mixed powder is used for the synthesis step in alchemy, because it is all powder, and it is necessary to find out the useful substances in it and refine it, so the requirements for spiritual power are very high. This was the most fundamental reason why Roy was reluctant to learn alchemy under various excuses at the beginning. According to Roy's own estimates, at present, if he wants to refine bone healing water, I am afraid that the success rate is not too high, because his spiritual power itself is not high.

And the key substances needed for the earth shell worm, hard bone vine, and bone sand chrysanthemum are clearly written in the "Introduction to the Alchemist". The key point is to fuse these key substances together through alchemy, and it is completed.

Roy carefully poured the three powders into a test tube and plugged the stoppers. Because there are no special tools, you can only shake it with your hands.

Roughly shaken evenly, Roy poured out all the powder and poured it into the center of another alchemy array. The formations used for synthesis and dismantling are not the same.

Roy pressed his hands on the edge of the alchemy array as before, his spiritual power soaked. The thunder element in the room was once again condensed into the alchemy array, and some pencil-sized lightning bolts lingered on the lines and spells of the alchemy array.

Roy took a deep breath, closed his eyes, and controlled the thunder element to modify and synthesize the molecules of the powder.

The synthesis lasted about an hour, and it was a very subtle activity, and any disturbance could cause the lightning element to be unstable and too much, causing excessive voltage and current to burn the powder. And even more unlucky, a sneeze blows the powder into the air, causing the dust to explode under the attack of the gathered thunder element. Fortunately, Roy completed the alchemy peacefully.

By this time, Roy was already sweating profusely. Because of the assistance of the alchemy array, it does not consume its own thunder magic power, but the consumption of spiritual power is too terrible.

The last step is to dissolve these powders in alcohol, because many of these powders are insoluble hydrophobic organic compounds, and only alcohol can be used for bone healing water. Originally, there was another step that should have been separated and purified for impurities, but the cost of separation and purification was too high, and Roy was too lazy to deal with it further because of mental fatigue.

The dissolving process is very simple, a volume bottle, pour the powder into it, add alcohol to the volume line, and then close the stopper and flip it up and down to shake well.

"Whew-" Looking at the bottle of 1,000 milliliters of bone healing water concentrate that he made, if he mixed it with water in the appropriate proportion, it would be done.
