Even if Fang Qiuling was not very willing, but the three bottles of potion were all placed in front of him, and it was impossible not to do it.

Some time ago, the days were too exciting, either dealing with goblins or fighting orcs, and then fighting with bone racks and zombies several times. At present, Fang Qiuling has lazy cancer and is in a "slack period". I really don't want to move......

Most of the refining process for secondary energy flasks and energy flasks is the same, with the difference being only the final "activation". Activate the ubiquitous mana in the space, infuse it into the potion, and soak the potion "mana" to achieve magic. This process is called "activation". However, most alchemists will charge it all at once, and sell the secondary energy potions that have been soaked in Mana as energy potions.

It turned out that it was only the amount of a bottle of energy elixir, less than five hundred milliliters, Fang Qiuling planned to be lazy, and the formal alchemy circle would not be drawn, and he would directly use the forbidden blood alchemy circle to get it, and it would be over in about ten minutes.

However, now that there are three bottles of potions to be soaked in Mana, it is not very suitable to use the blood alchemy circle.

The alchemy circle of blood, as the name suggests, is a circle drawn with blood, that is, the alchemist directly outlines the circle with his own blood. Because the "material" used to draw the circle is blood, it is very reminiscent of "dark magic", and the temple must have banned it, and the alchemist guilds of various kingdoms also have a negative attitude towards this alchemy circle. In addition, the ultimate blood alchemy circle is almost the same as the sacrificial circle, except that the carrier of power dedication has changed from the existence of gods, godheads, saints, etc., to a specific artifact. Therefore, the Blood Alchemy Circle was naturally labeled as a taboo.

As far as Fang Qiuling knew, there were not many alchemists who had mastered the skill of the Blood Alchemy Array in Elune. On the one hand, it is listed as taboo and it is no longer possible to obtain relevant knowledge from formal channels. On the other hand, it is also because the inheritance of the relevant knowledge has been lost, and this skill can be regarded as lost magical knowledge.

However, for players, the Blood Alchemy Circle is not a secret at all, and slightly more experienced players can draw it out of thin air. This technique has a very obvious advantage, you don't need to prepare special materials to outline the alchemy circle, you only need to blet blood, which is very suitable for laziness or cost saving. But the flaw of this technique is also obvious, which is commonly known as "bleeding". Health is deducted during alchemy, not mana consumed during regular alchemy. It is precisely because of this biggest disadvantage that those professions with extremely high health but zero mana have basic alchemy abilities - emergency refining of some magic potions for first aid, or a temporary alchemy enchantment or something to temporarily improve a little combat effectiveness.

As a player who had practiced alchemy to the master level, Fang Qiuling was familiar with the Blood Alchemy Array. From the most basic small magic circle to the ultimate forbidden circle, you know it by heart. Several elementary and ultimate circles can be drawn directly even with their eyes closed.

The total amount of the three diluted vials of energy potion added up to almost 1,400 milliliters. A small blood alchemy circle can't be handled, that is, two bloodsheds. If you use a higher-level Blood Alchemy Circle, you can get it all at once, but the "raw materials" required are three times as large as the small Alchemy Circle!

Draw the alchemy circle of blood to bleed. Fang Qiuling felt that it didn't matter if he let out blood once, but twice was a bit of a problem. A higher-level circle is three times the amount of a small circle, which is a bigger problem, and it will directly be anemic!

Fang Qiuling's purpose in using the Blood Alchemy Array was to be lazy. It takes more time to build a standard alchemy circle, mainly because of the magic resonance of the circle, and half an hour is the minimum. And the alchemy of blood, it can be done in ten minutes, and there is no need for magic resonance at all, because the blood released is all your own!

Now it seems that it should really take more than half an hour to make the alchemy array, and it is more cost-effective to soak the mana of the energy potion in five minutes. Anyway, the completed alchemy circle will not be wasted, and you can still practice for the kitten charms in the next few days, killing two birds with one stone.

Thinking of this, Fang Qiuling had no choice but to sigh and start working honestly.

Anyone who has knowledge of geometry in the present world knows that the judgment of the naked eye is actually very "emotional" and full of all kinds of errors. Obviously, it is the same pattern of shape and size, but because one is horizontally placed and one is erected, what the naked eye sees is one large and one small. Obviously, they are two lines of different lengths, but due to the relationship between them, they look exactly the same length.

Fang Qiuling was admitted to the university majoring in mechanical manufacturing, which has a course called mechanical drawing. This course is a hands-on, applied course that teaches students how to use drawing tools such as T-rulers, compasses, pencils, etc., to sketch and dimension complex mechanical parts.

This course is undoubtedly the specific use of geometry in the mathematics course, and it has very strict and clear requirements, because the workers in charge of manufacturing are processed and manufactured according to the finished drawings. Even a mistake in a line or a shift in a curve will cause the machined part to be unusable.

And Fang Qiuling can proudly announce that his score in this course has not been lower than ninety, and he has also scored full marks several times! He has a lot of experience in how to make maps quickly and accurately. The work of sketching a magic circle is the same as mechanical drawing.

In Elune, the skill tree in the "math field" is mostly hidden. I don't know where the technology of "geometry" is, and scholars have not yet completed the induction and summary of common geometric figures. When drawing magic circles, the casters mainly follow the teachings of their teachers and the descriptions in the books. The accuracy of the magic circle is often determined by the experience of the person who draws it, and it is not surprising that there are many problems with the magic circle drawn.

Every year, because the magic circle is not standard, the magic array explodes, or the strange monster bound in the magic circle breaks free, which leads to the injury and death of the caster. Of course, Fang Qiuling would never make such a low-level mistake.

Since it is necessary to work "overtime" at this point in time, how can a person work overtime? Grab an assistant to help.

- Eliza, it's up to you!

Of course, it certainly can't be said so bluntly. Eliza was a good boy, and she would have been willing to ask her to help with the work. But in this case, Eliza's parent, Old Tom, will definitely have an opinion.

"Eliza, let's continue yesterday's lesson." Fang Qiuling shook the three bottles full of secondary energy elixirs, "The content of today's class is to infest the potion with Mana. Eliza, let's review the part of the basic course about Mana infestation in the previous day. First of all, what is Mana infected? ”

Eliza sat upright with a pencil in one hand and a small notebook in the other, and knew at a glance that she was a good child with excellent character and learning.

"Mana infection refers to a natural and unstoppable activation phenomenon of mana on objects and human bodies with a high concentration of mana in the spatial range."

"Very well, Eliza. The second question, Mana infestation, is this a good thing or a bad thing? ”

The question of "hmm......" is a bit of a junior, and Professor Fang Qiuling did not mention it in his content, but he described in detail the possible consequences and phenomena of Mana infection. Eliza was stunned for a moment before she said in an uncertain tone, "Eliza thinks this is sometimes a good thing, but sometimes it's a bad thing. ”

Fang Qiuling casually took the wooden board that Sino had found, then nodded slightly, and motioned for Eliza to continue.

"In the process of alchemy, we need to gather as many manas as possible and inject as many manas into the alchemy object as possible to make the level of mana infection as high as possible. In this way, the effect of the medicine will be good. However, when Mana infestation is not needed......"

Eliza is stuck, and her knowledge and experience are not enough to exemplify the undesirable phenomena that occur when Mana is overinfected.

"Eliza-san, you're right. When it comes to alchemy, usually, we want the higher the level of mana infestation, the better. Fang Qiuling specially added an accent to the word "usually", "But there is a limit to everything." The more the merrier means that you can reach the upper limit as much as you can. However, once the upper limit is exceeded, the potion that could be used to heal will become a mutation-inducing ...... It can't be said to be a poison, and the side effects are huge, but it is estimated that it can't kill people. ”

Eliza nodded as if she didn't understand.

"That's a bit too far, Eliza, you're still a beginner, so you don't have to worry about Mana's over-infestation for the time being. Because your strength is not yet possible to cause Mana to go berserk. But you have to know that Mana is not only a friend of the caster, but also an enemy of the caster at times. ”

"Yes! Teacher! ”

"Alright, that's the end of the review. This is followed by today's specific lesson, how to gather as many manas possible. Fang Qiuling knocked on the wooden board in his hand, "I don't say that you should have guessed it, today is about the alchemy array." ”

The cat's ears on the top of Eliza's head were straight, and the tail behind her was unconsciously erected.

"The function of the alchemy circle is to gather the free forms of Mana in the space to speed up the penetration of Mana or form a magical resonance, so it is necessary to choose materials with a better affinity for Mana to draw and carve. At the same time, it is necessary to consider the repeated use of the alchemy circle after a painting to reduce the repetitive drawing work, so the material selection needs to be tough enough to resist the Mana backlash that occurs during the alchemy process. Based on the requirements of these two, Eliza, what materials do you think is better? Planks, how's that? ”

"Well, Eliza thinks...... Wooden planks are not a good material. It's relatively brittle, and fire should often be used in the alchemy process, and if you accidentally burn it, it will ......"

"That's a good answer, Eliza. Wooden planks and wooden materials are really not very suitable. But there is nothing else for now, so I have to leave it at that. However, not all wooden materials are not suitable for drawing alchemy circles, for example, the cold fir and cold forest pine of the endless glacier in Shino's hometown are very good materials. This is because of the regional relationship, because the trees of the Endless Glacier have been in a cold environment for a long time, which causes the trees themselves to be soaked with wind and ice elements. The fire sunflower tree and Yangui on Huolong Island in the south are similar. However, these special woods are hard to come by if they are not local. Even if there is, the price will not be cheap. ”

Fang Qiuling put the plank on the ground, and then made a simple compass out of a dagger, rope, and stick.

"Most of the metals are Mana's 'bad conductors', and although the more common Adamantite and Mithril are 'good conductors', the price is too scary, and the same weight of Adamantite and Mithril is almost equal to ten to twenty times the weight of gold, and it is generally not available. Although metals such as cold iron and flame steel are also good, the gathered mana will obviously have elemental attributes, and it is not recommended to refine specific elixirs, not to mention that their prices are also very ......."

Fang Qiuling sighed and continued in a serious tone:

"Eliza, the teacher is also a poor person. I haven't seen anything really good, and now I have to talk big and lie to you. ”

"Poof......

Eliza, who listened to the class with a serious face, and Lily, who was cheeky and rubbed the class, laughed out loud.

Old Tom, who pretended not to care, but always pricked up his ears to monitor the quality of teaching, pouted, and a look of contempt appeared on his face.

- This stinky boy is talking nonsense and deceiving people again!

"Ahem, get down to business, get down to business...... The wood is brittle, and the mana affinity of the metal is not good. So most of the time we choose to use stones, drawing on large slates. Once the slate is finished, the slate is carved so that the circle leaves at least one knuckle depth on the slab so that it can be used repeatedly. After all, drawing an alchemy circle is a time-consuming and energy-consuming task. If there is no problem with drawing and carving, then we can consider making a stand under the slate and making the slate directly into a table. With the addition of alchemy utensils such as flasks, measuring cups, heating tools, etc., the simple alchemy workbench is completed. ”

- Except for the core alchemy circle, the other things are basically the same as the equipment used in the chemistry laboratory class in the present world.

"There are many kinds of stones, and the requirements for selection are nothing more than those two points. If possible, you can choose obsidian. Obsidian is hard and thick, obsidian naturally has a fire element, and obsidian is an ice element, both of which are very good. The price is also appropriate, but it needs to be processed after getting it back, which may be a bit time-consuming. ”

A cheeky Lily raised her hand.

"What's wrong, Lily?"

"Is obsidian okay?"

“…… Of course. Fang Qiuling glared at her, "I know that there is an alchemy table made of obsidian in the Temple of Eros, and that thing is the core of the 'Third Workshop'!" ”

"Hehe......" Lily gave a thumbs up, "Awesome, even the 'Third Workshop' knows it." ”

How could Fang Qiuling not know about this thing. As a master alchemist, when refining high-level potions, you need to borrow various bonuses from the alchemy workshop to increase the acquisition rate and success rate of potions. Players need a lot of resources to build their own alchemy workshop, which is basically impossible to achieve without the support of the player's guild. Therefore, borrowing the NPC's alchemy workshop for temporary use is the choice of most alchemists when refining high-grade potions.

The third workshop of the Temple of Eros is the favorite of idle players and small guild players like Fang Qiuling. Because the Goddess of Love Temple has a low fee, a superior geographical location, and relatively low prestige requirements, you can also stop by to see the beautiful young lady. Fang Qiuling has to go almost every day in the game.

"Not only do I know about the 'Third Workshop', but I also ......"

Fang Qiuling suddenly covered his mouth.

- It's so dangerous, I almost missed it!
