Polu knocked on the door, but no one answered, and the door did not open. He knocked again, but five familiar magic circles appeared on the door. If he recalled it carefully, he seemed to have seen it in the teacher's book?
Cold sweat soaked his back: "It won't explode even if you enter it wrong, right?" If it exploded at this size, how far would it be safe to run?
He hesitated for a while, then decided not to take the risk, and knocked on the door a few more times. The magic circle suddenly disappeared, and the door opened silently inwards.
Zhu Yiwei showed her head from the door and smiled softly: "Bolu? Why are you here? This is the first time I have seen you here in a long time. Is there something wrong?"
She opened the door and motioned for Polu to follow him in. Polu looked curiously at the furnishings that were different from those in his memory. He casually replied: "Ah, I have something to discuss with the teacher. How is the progress of your research?"
"It's not good." When she heard that he was not here to find her, her face with her back to Bolu suddenly became cold.
After walking around a patchwork of test benches, Polu said to her with a smile: "You look much better when you smile than when you first came here with a straight face." He waved to say goodbye, leaving Zhu Yiwei in a daze, far away.
Walk towards Landau from a distance.
"Teacher, this door is pretty good. Can you try to install one for yourself later?" He lowered his head and walked into the large and spacious laboratory.
Behind a large area of crystal tubes, Landau was observing the solutions emitting dangerous blue light and copying something in his hand. Polu walked over and said: "Teacher, I'm back!"
"How is it? We are not in danger, are we? How is the effect of the artillery?" Landau spoke, but the work in his hands did not stop.
"It's pretty good, but there are a lot of things that can't be hit by artillery."
"Huh, that's just because the kinetic energy is not enough. Increase the caliber and try again."
"That won't work." Bolu laughed: "We can't make bigger cannons for the time being. We have encountered problems in iron-making. Now the Great Melting Furnace has stopped production. That's why I came here."
"Huh? Why don't I know? No one has come to see me." Landau seemed to take it seriously. "Wait a minute, let me finish the work here first."
He speeded up his hand, quickly recorded the situation in the crystal tube, and then put down the notebook in his hand.
"Why has production been discontinued? What's the problem?" He sat down in front of the workbench.
"The quality of steel is unstable, and we need a method that can analyze the composition of steel." Bolu placed a cup of steaming tea in front of him. "How did those alchemical processes complete the separation of meaningless components in the past? I now
I haven’t figured out a good solution yet.”
"What kind of stupid question are you asking? Of course it relies on magic power!" Landau's face showed an expression like "How can I have a stupid student like you." At the same time, he guided an analysis array and a classification array. Monitoring and analyzing at the same time
The magic circle, while operating the classification magic circle, uses the corresponding magic wave from the classification magic circle to gather specific impurity solutions together, and then takes out the controlled objects..."
At this point, he paused and glanced at Polu. "If you don't have enough control, you can just use a spoon to scoop it out, but can't it be separated? Isn't the rest just metal with very good purity? High-level magic
All conductive materials are purified using this method."
Bolu was dubious: "Teacher, please don't lie to me. Although I know there is such a thing as a classification circle, but when you tell me about the whole process, how can it be so simple? Can it still be used to do this?"
"It's that simple! Do you think that all high-level alchemists are just doing it for a living? This problem can't be solved? Then what else can you do? The classification circle was invented to separate various solutions and metals that are difficult to dissolve and separate.
Extract impurities." Landau showed a matter-of-fact expression.
"Then why haven't I heard of it before? Doesn't it mean that iron can be extracted directly from iron ore?" The intensity of Zentraedi star technology frightened Bolu. So as long as it is strong enough, it can even be extracted from iron ore with bare hands.
Ore to draw weapons?
"Are you stupid? The classification circle can't do this kind of thing. It can't change the properties and can only classify the same substances. So if you release this circle on a pile of ores, you will get nothing more than ore powder.
It may be that the metal is extracted directly. And it is much more difficult to extract from the solid than the liquid, so it still has to be smelted when it needs to be smelted."
Langdao was stunned and couldn't help but laugh. "I almost forgot that you haven't been studying for a long time. Okay, it is indeed quite difficult for you. You really need to be advanced to analyze and classify the operation of the double array.
You have to be able to guide the same huge amount of magic power to operate it. Your little control is really not enough."
"That's just right. Since you're not busy now, let me give you an assessment. It's almost time to do the math." Landau stretched out his hand and constructed a new array model in the air: "It is made purely of mental skeleton.
Then guide it and show me how to operate it."
Bolu looked at it: "Isn't this the shaping circle?"
"Yes, the first level assessment, I know you can do it, let's go through the formalities, hurry up." Bolu quickly formed the formation, smooth and natural.
"Yes, it seems that the hard training before was not in vain. Okay, let's move on to the next step."
A magic circle that was similar to the shaping magic circle but seemed to have been changed appeared in Landau's hands. He did not rush or disperse the magic circle, as if he wanted Polu to learn the magic circle on the spot.
Bolu carefully observed it, built it according to the sample, and corrected a few subtle errors. After that, the circle finally started to operate successfully.
Landau nodded and showed an appreciative smile: "That's right, continue. Pay attention, the key this time is the control of changes."
This time, the magic circle in his hand is no longer a fixed whole. There is a set of runes in it that are constantly changing, causing the magic circle to emit different colors of spiritual light.
"Teacher, this is a dynamic magic circle, right? I haven't practiced it before, is it a bit too difficult?" Bolu, who had never tried this seemingly advanced technique, felt a little lack of confidence.
"Try it, and you won't be charged any money anyway. If you learn this, you don't have to stop and switch the arrays, and the processing efficiency will be greatly improved." Landau, who was maintaining the array, seemed very relaxed, and he could even open it.
A joke to relieve Polu's nervousness.
Polu carefully observed the flickering structure of the magic circle's runes. Facing an empty wall, he began to use a mental skeleton to build his first dynamic magic circle in his life. The skeleton was built well, and he waited until the runes in it were flipped to proceed.
During the change, he felt a heavy
The burden weighed on his spirit. The huge pressure made him feel a little depressed, and the swaying mental power gave him a dizziness that only occurs when spinning rapidly. He took a hard breath and used all his concentration.
, successfully transformed the skeleton 5 times.
Unfortunately, this flip is very slow, but I can only support this number in one breath.
"Try!" He gritted his teeth and injected the magic power he could channel into the skeleton. The magic power lit up like a neon light in each filled rune and skeleton, and began to work.
"1!" The rune was converted once. The conversion with magic power is much more difficult to control than just converting a skeleton. It seems to have a heavy inertia. It will start to move on its own after you toggle it for a while.
"2!" Polu's dizziness has reached a very severe level. He is swaying and trying desperately to stabilize the magic circle in his hand.
"3!" There seemed to be something ringing in his brain. He felt no longer dizzy. The area around his vision gradually darkened, leaving only his unconscious arms surrounding the glowing magic circle. "Convert!
Turn it for me!" He murmured, moving his lips that had turned blue and white, staring blankly at his hands, and the hot air exhaled from his nostrils brushed against his own lips. The last conversion of the runes
It was completed with difficulty! The magic circle automatically rotated.
Polu gave up control of the magic circle, waved his hand, and dispersed the magic circle. He sat down on an empty chair next to him, supporting his thighs with his arms, sweat dripping from the hair on his forehead to the ground, and suddenly
Take a breath.
The leaves of the natural ancient tree hanging on his chest now transferred a kind of warm energy to him. This made him feel a little better from the headache caused by the completely dried up mental power. Landau handed over a test tube: "Drink
Lose."
Bolu took it and poured it into his mouth.
There was a strange taste like an iced drink. His throat hurt from being stabbed. Only then did he regain a little strength: "Teacher, what is this?"
"I found the recipe for a mental recovery potion in the library a few days ago. I happened to see such a thing, so I tried to make two of them to see if I could sell them to mages."
Bolu was stunned as he held the empty test tube: "So this is considered a drug test?"
"It's okay. The potion is definitely not poisonous. It mainly depends on the recovery effect. Stop talking now and have a good rest."
Landau stepped aside and began to pour something on the workbench.
