With Fang Qiuling's words, the bottle placed in the center of the alchemy circle began to glow.

Unlike the chaotic and violent form of the first "chaos", the Mana that forms a complete cycle is quite gentle. Like a gentle tulle, it slowly wrapped the bottle.

A sparkling and soft glow soon leaked out of the bottle, and the dark gray transparent liquid gradually became more transparent.

Fang Qiuling had unconsciously let go, and the alchemy circle was already completely under Eliza's control. However, Eliza didn't notice it, her eyes were a little more joyful, and she was looking at the bottle in the center of the circle with anticipation. It feels really good to watch your own strength change the potion in the bottle little by little, and this kind of scene that seems to be fruitful after labor.

The sparkle did not last long. As the liquid in the bottle all turned into an equally transparent dark gray liquid, the glow began to fade.

"Eliza-san, you're doing a great job. The process of Mana's infestation is almost over. Now slowly, little by little, the mana output is reduced. and limited intervention in the Mana circuit in the circle. ”

Eliza didn't dare to speak casually, nodding her head or waving her arms to indicate that she heard. The first time she ran the alchemy circle, she was afraid that she would accidentally interrupt the process of infecting the secondary energy elixir. But in addition to nodding and waving, Cat Mei also has other body language that indicates hearing and understanding.

I saw that the vertical ear on the top of Eliza's head turned twice quickly, and the vertical ear of the Q bomb accurately expressed the meaning of "received", "understood", and "no problem". This made Fang Qiuling a little confused, but Fang Qiuling was only in a daze, and then continued to guide:

"I have already talked about the origin and evolution of the six-pointed star circle. According to its evolutionary history, in the simple process of alchemy, alchemists split the six-pointed star into two triangles and used it. The upward triangle, it is seen as 'fire'. The downward triangle, which is seen as 'water'. The integration of 'water' and 'fire' with each other, the growth of each other, and the cooperation with each other is one of the core theories of alchemy. ”

The ears on top of Eliza's head began to turn again.

"At the beginning of alchemy, the magic is injected from the nodes at the top of the triangle on the 'fire' side, driving the nodes on the left and right sides, then activating the nodes on the triangle on the 'water' side, then converging on the nodes at the top of the 'water' triangle, and then returning to the 'fire' triangle along the outer arc loop. Although there is a circuit between the two triangles, the operation of magic is completely unrelated. They echo each other in the form of resonance, and gradually balance each other, reaching the equilibrium point of magic. Once the balance of 'water' and 'fire' is reached, the magic is restored to mana. Of course, different power systems have different names for the 'energy' restored by the circle, wizards and warlocks call it 'Mana', shamans call it 'elemental', priests and paladins call it 'divine power', and the sword fairies of the East Road call it 'spiritual power'...... However, no matter what the name is, there is no difference in their essence, they are all the embodiment of the Source Power in reality. ”

Eliza's ears twitched twice, then froze. Should be...... I understood the first part, but the second part didn't.

Fang Qiuling blinked, and decisively limited the content of the lecture to the alchemy array: "The last step in the alchemy process is to stop the alchemy array so that it no longer has the additional magic power that appears. What we have to do is to slowly stop the alchemy circle. When activating the alchemy circle, start from the 'fire' side, then stop is the opposite, starting from the 'water' triangle. ”

Fang Qiuling also stretched out a hand and put it on the wooden board.

"There are several things that can be done to stop the circle. For example, the easiest and most brutal way is to run away, and the farther you run, the better. It's nothing more than a 'boom' explosion. As long as you run fast enough, the explosion won't blow up. ”

Eliza's earlobes were lowered, and the meaning should be ...... ">_<".

"Hey, kidding, let's get down to business. When the circle is activated and enters the running state, the mana of the internal loop is in balance. Increasing the infusion of mana from the side of the 'water' triangle slightly disrupts the balance in the circuit, causing the mana on the side of the 'fire' triangle to drain, and then restoring the balance again. Repeat this process, then the magic in the circle will be exhausted little by little, and the circle will eventually stop working. ”

Fang Qiuling's hand on the wooden board slightly emitted a silvery-white glow.

"Eliza-san, feel it carefully. I'm going to slowly inject magic into the 'water' triangle, very slowly, very slowly. With your perception it should be able to capture. ”

As the silvery-white brilliance in Fang Qiuling's hand gradually increased, the brilliance on the alchemy array gradually dimmed. The process is slow, and those who have been watching the circle may not even notice it. However, Eliza does not see with her eyes, but perceives with her "heart".

In Eliza's perception, the "brightness" of the alchemy circle continued to weaken with the injection of Fang Qiuling's magical power. From the beginning it was as bright as a bonfire, to the light of a grain of rice on the tail of a firefly. Fang Qiuling's way of injecting magic power was very ingenious, due to the bursts of pulse waves, each time it caused the loop to oscillate, but as soon as the oscillation was generated, it would be calmed by the next magic pulse.

"When the 'water' triangle is injected with mana, it can also reduce the mana injection on the side of the 'fire' triangle at the same time. This will stop the circle faster. However, whether it is to inject mana from the 'water' triangle or reduce the mana injection from the 'fire' triangle, it is necessary to pay attention to the balance of mana in the circle circuit at all times. A slight imbalance of mana is our goal, and the natural adjustment of the circle and our active guidance will restore the balance of the mana in the loop, thereby weakening and reducing the total amount of mana in the circle. The total amount of mana gradually decreases, and the mana in the loop will run slower, and finally all the mana gathered on the circle will be dispersed, and the circle will stop. ”

Fang Qiuling paused slightly, and then showed the expression of "full of malice" when he just said, "As long as you run fast enough, you won't be able to explode".

"Eliza-san, do you know what the consequences will be if the magic of the circle is out of balance?"

- The consequences? What can be the consequences, of course, it will explode directly.

Eliza's eyes froze for a moment, then widened wider than ever. The vertical ears on the top of the head also turned wildly.

- Brother Thurik! I know, I know! Please don't!

"It seems that you don't need to say it, you already know." Fang Qiuling nodded with satisfaction, "Eliza, you can let go." The circle has stopped. ”

"Ah...... Oh! ”

Eliza jumped up and hid behind Lily in an instant, revealing only a small head, looking nervously at the magic circle in Fang Qiuling's hand.

"Don't be afraid, don't be afraid."

Lily whispered to comfort Eliza, and Lily was also startled when Fang Qiuling said "what consequences" just now. Fang Qiuling is also very nervous sometimes, in order to make a "deep" impression, he can make the lower limit very low when doing things. In order to let Eliza deepen her image and understand in advance what a magical imbalance is, it is not impossible to directly let the wooden board in her hand "boom".

So Lily spoke directly: "Hey! Don't blow it up! ”

"Why?"

"No why! Just don't blow it up! ”

"Oh, okay. If you don't blow it up, don't blow it up. I just want to hear a loud ......" Fang Qiuling shrugged his shoulders, and then he remembered, "By the way, I still plan to keep this thing as a teaching aid, it really can't be blown up, it can't be broken." ”

Eliza's little face suddenly puffed up, puffing up like a little pufferfish.

- Stinky brother, bad brother! Just know how to bully Eliza!

"Alright, that's the end of today's make-up lesson. Eliza-san, I'll leave this thing to you. Fang Qiuling snickered and stuffed the bottle on the magic circle in his hand to Eliza, "Eliza, don't forget the rules of alchemists." ”

- The rules of the alchemist?

Eliza's puffed little face suddenly became more rounded.

At this time, which one can be said to be the rules of an alchemist? It's nothing more than taking a sip of it after the potion is refined.

If this rule is reasonable, Eliza thinks it is completely reasonable, and there is no problem at all. However, what I am holding in my hand now is the energy potion that has been infected by Mana, and if there is no mistake in the refining process, the effect of this potion is better than the energy potion sold in the adventurer's guild!

If she really took a sip now, Eliza felt like she wouldn't have to sleep tonight. As for why Eliza knew she didn't have to sleep all night, of course, it was because she accidentally drank it once. The pot is to be carried by Old Tom. Old Tom had a habit of putting things around, and once Eliza came to play in his broken wood house and saw that she was thirsty, and then saw a bottle of "water" on the table, so she took it and drank it, but she didn't expect it to be an energy potion......

Lily quietly tugged at Eliza's sleeve and grabbed Shino again. Then the three of them began to whisper.

It's definitely not okay to go one night without sleeping. Although she is still young, Eliza still has some confidence in her appearance. It's definitely not as good as Shino, but as a little beauty, staying up late and not sleeping will have dark circles under your eyes, which is the enemy of beauty!

Since you don't plan to drink it, you have to find a "substitute ghost". For the dead ghost, the body should be stronger, in case of poisoning, it can be saved; The energy potion has the effect of "refreshing the mind", and it is best to be the person who is on duty tonight; In addition, it is better to "cheat" the guys, otherwise most of them will not drink. Who in the team fits these bills?

Before Lily and the others could come up with a result, Old Tom helped them out.

"Yo, you're done?"

"Well, yes......"

"Where's the stuff?"

"Here."

Eliza raised her little hand, and the bottle in her hand reflected the light of the campfire, looking red.

Old Tom bent slightly down to take the bottle. He still looked at the color of the liquid in the bottle, then opened the lid and smelled it.

Eliza immediately sensed Old Tom's intentions, and quickly jumped up and exclaimed, "Daddy, I haven't drunk this thing yet!" Not yet, not ...... yet."

It is the responsibility of an alchemist to test medicines, and it is a responsibility that cannot be shirked. As a good student, Eliza clearly remembered what Fang Qiuling said about "professional ethics" when she first took an alchemy course. If you have not tested the medicine yourself, you must not give it to others.

Old Tom touched Eliza's head, and his face, which had always been described as "fierce and vicious" by Fang Qiuling, was a little more kind: "It's okay, Dad, I'll help test it." ”

"No! No way! ”

Eliza was a good and serious boy, and she grabbed Old Tom's hand and jumped unrelentingly, trying to get the potion back.

"Didn't that stinky boy make me a teaching assistant before today's class? Teaching assistants have the duty and responsibility to protect students from harm. Old Tom held his hand high so that Eliza couldn't reach it, "Don't worry, Daddy, I'm familiar with this thing, it's fine." Didn't your Uncle Ed take a sip just now, it's fine. ”

So saying, Old Tom opened his mouth and brought the bottle to his mouth......

- Wait!

Old Tom's hand froze for a moment, and then he hurriedly took out the cup he usually drank from his waist, poured a small half cup, and then poured it into his mouth.

Fang Qiuling's previous remarks about sharing cups and cutlery had already disgusted Old Tom. As an old Tom who doesn't have any "that inclination", he now also prepares his own cutlery and never shares it with anyone else.

Old Tom loved to drink. Perennial drinking has more or less damaged his taste buds, and the slight bitterness of the energy medicine is usually not experienced by him. But as the dark gray transparent liquid entered the mouth, the tip of the tongue immediately became heavily bitter, and the bitterness had a distinct burnt taste. Compared to the energy potion bought from the adventurer's union, the bottle of energy potion refined by his own child in his hand was quite poor in taste.

“…… It's bitter, and it smells mush. ”

Old Tom's brow furrowed into a pimple.

Fang Qiuling's voice came from the side: "The heat was not well controlled when cooking the medicine, and the herbs were generally overcooked. More of the 'bitters' in herbs are released. In addition, I didn't pay attention to controlling the temperature when filtering. Seeing that the liquid medicine in the pot could not be filtered, he took it and reheated it. After heating, it was not filtered and condensed, and then it was burned on the fire. This burned more than once, and the bottom part of the pot was all mushy. Hehe, there is a pot that is simply burnt. It should be heated without stirring. ”

Regarding the work of Old Tom directly resulting in the drug test, Fang Qiuling said that it was not strange at all. Although Old Tom looks like five big and three thick, in fact, this white-haired old man also has a tender side. Of course, don't say that to his face. The consequence of saying it is a direct old punch.

"Daddy, how do you feel? Do you have an upset stomach or difficulty breathing? ”

"Shhh...... No, neither. ”

"What about the spirit? There is no feeling of being cheered up. ”

"Hmm...... Yes, I didn't feel anything about the entrance just now, but now I have. But it doesn't seem to be very strong...... A little bit of feeling. ”

"Oh, normal. The effect of the potion is relatively slow, which is probably caused by the insufficient infestation of Mana and the long time...... Well, that means it's fine. Safe! ”

Fang Qiuling gave a thumbs up, and in response to him was the white eyes of the surrounding brushes.
