Austin's discovery stemmed from a theft in the lab.

In the past month or so, in the secret realm laboratory he is in charge of (mainly researching the properties of various secret metals), the inventory of secret copper has often disappeared.

When Donner heard this, he thought that Austin had discovered the miraculous phenomenon of all the secret copper falling into "void". But that's not the case.

At first, Austin didn't pay much attention to this matter, after all, secret copper is the most common secret metal, the price is low, and the corresponding management is also very loose, and it is understandable that there are occasional omissions.

However, when the thefts continued one after another, Austin finally couldn't sit still. One day half a month ago, he summoned all his more than 30 apprentices to the laboratory, and before he could speak, the perpetrator of stealing the secret copper immediately confided his true feelings.

Speaking of this, Austin took out a small golden ball from his bosom and said, "Only then did I know that my laboratory had become a den of thieves, and every child had a few of these small beads in his pocket. ”

As he spoke, he handed the small secret copper ball the size of a glass marble to Donner, and continued, "My lord, I hope you will forgive those children...... I found out afterwards that this happened because there was no fireplace in their dorm. You know, the winter in Pamplo is really hard. ”

When Austin said this, he couldn't help but be a little embarrassed, because William, the acting city lord of the school city, was on the side, and when he said this, he was complaining about the living conditions of the school city.

However, Donner didn't care about this at all, the moment he took the secret copper ball from Austin's hand, his face changed, and he immediately asked, "There are no magic crystals in here, right?"

"Yes, my lord, there are no magic crystals," Austin smiled knowingly, "I was skeptical when I took this little thing from the children, but I thought about it, how could those children get their hands on the magic crystals? ”

"Dwarven totem?" Donner's brow furrowed even tighter.

"That's right, it's the dwarf's totem. Austin explained, "One of those kids had spent two years at the engineering academy in Fog City and had seen the totem pattern on the dwarven sword...... According to the child, a few months ago, he had made a small secret copper dagger in the laboratory, and imitated the pattern of the dwarven totem, and used the magic gold from the experiment to draw the same pattern on the dagger......"

Donner listened attentively to Austin's narration, not only with a solemn expression, but even subconsciously slowly stood up.

"My lord......" Austin was a little frightened.

"Then you say, what does the dwarf totem have to do with this secret copper orb?" Donner asked impatiently.

At this time, everyone in the courtyard had already sensed his abnormality - even after learning that Todd had discovered the true magic element just now, Tang An did not lose his temper like this.

"It was so, when the boy had finished making the dagger, he did not dare to take it for himself, for fear of being discovered, and pressed his little work into a thin sheet of secret copper with the clockwork forging machine in the laboratory. According to him, the totem pattern on the surface of the dagger disappeared when it was pressed by the forging hammer, and the secret copper was always warm. Auston continued.

"So, after the winter, they concocted these secret copper balls according to the law to keep warm?" asked Donner.

"Yes, sir. Austin nodded.

At this time, Lisa, who had been silent, suddenly stretched out her hand to Donner and said, "What is it?" She couldn't understand the conversation between Donner and Austin, but seeing that the two had been talking for a long time, it seemed that the center of the conversation was on this inconspicuous metal ball, so she became curious and couldn't help but ask.

Donner handed the ball to Lisa and instructed, "Don't use mental power to probe. ”

Lisa nodded, took the secret copper ball, put it in front of her eyes and looked at it for a moment, and said disdainfully: "Except for some warmth, it's not magical." With that, he returned the ball to Donner.

Donner ignored Lisa's cynicism and asked Austin instead, "How long have they been using?"

"Do you mean this secret copper bead?" Austin said, "It should be almost two months." ”

"It's been at this temperature, and it's not going to fail?" Donner asked in a deep voice.

Austin's expression was a little nervous, he didn't seem to expect that the Duke would pay attention to this little discovery here, and he was not very sure about the question.

"There shouldn't be any exhaustion...... I do not know. He replied honestly, then scratched his head before saying, "My lord, I think this method may be used to warm the apprentice's dormitory, after all, secret copper is not expensive." ”

"Heating?" Donner looked at the secret copper bead in his hand, frowned, and said to himself almost inaudibly: "Dwarf totem...... The answer lies in the dwarven totem. ”

Everyone on the spot, only Lucia and Lisa's perception can hear Donner's self-talk clearly, but Lisa can't understand Western, but Lucia understands, but she is even more confused.

"What's the answer?" she couldn't help but ask.

Donner suddenly looked up, looked at Lucia, and suddenly seemed to think of something, and asked thoughtlessly, "Do you remember the magic spell?"

"I remember. Lucia replied with a puzzled expression.

"Read a paragraph and try it. Donner said.

"Water or wood? I'll only do both. Lucia said.

"Try them all. Donner said as he stretched out his hand towards Lucia, and on the flat palm of his hand was the secret copper bead.

Lucia didn't know what he was going to do, but she began to chant the incantation.

"Wake up...... Wood spirits sleeping in the air. ”

The tone of the wood spell is much brighter than that of the fire spell, and it is said that because of the different pitches of the mantras, the fire and earth mages are mostly male, and the water and wood are mainly female, and the wind mantra is dominated by the tone of the mantra, so both men and women practice it. Of course, this law only works in Middle-earth.

As the sound of Lucia chanting the incantation sounded, Donner frowned slightly and closed his eyes, as if thoughtful. He tried hard to feel the temperature of the secret copper bead in his hand, and seemed to feel a slight change, but he was not sure.

At this moment, in addition to Lucia's incantation, another voice sounded in my ears, like a strange sound of hooring, and like a wounded beast roaring.

Donner opened his eyes and saw that Lisa's mouth was half-open, and he immediately understood what was going on. Lisa couldn't understand the spells spoken in the Western, but the magic spells had nothing to do with the meaning of the language, only the tonal frequencies at work, so Lisa could hear Lucia chanting the wood spell on that basis alone.

Compared to the magic spells that circulated in Middle-earth, Lisa's spells directly issued with fixed frequency changes had a much more obvious effect. Donner could feel that the wood-based magical elements around him were becoming extremely active. This change is very different from the effect of mental agitation. To give a more figurative example, the former is like the smell of flowers in the spring air, and the latter is like a hurricane.

Now, Donner doesn't have to close his eyes to capture it, he already has a definite answer.

I saw him clench his fists tightly, and then laughed mercilessly.
