“...... I heard that the headquarters of the Court Mage Guild of the Kurkut Empire was attacked, and the prisoner is unknown, but it is said that it is very likely to be someone from Cloudsdale. ”

"Hmmm......"

Hearing Latinia's words, the maid nodded absentmindedly, and the eyes of several 'people' present were attracted by the bare thread in front of her.

"I feel ......"

Ziegler, whose eyes were closed, suddenly opened his eyes, and at this moment, his eyes were full of surprise, and he couldn't help but murmur: "It's really a successful construction!"

"But the last time it lasted only three and a half minutes, let's see how long it can run this time. The maid shook her head and sighed.

There were only four of them in the vast laboratory, and even Latinia's attention was completely absorbed by the circle made of copper wires, and she subconsciously held her breath.

Sting!

Cervantes looked at the pocket watch in his hand and pouted, "The running time, three minutes and forty-six seconds, is sixteen seconds more than the last time." ”

However, it didn't work!

Everyone present couldn't help but sigh, although it was better than the last time, it was only sixteen seconds more, and it was completely useless.

The maid wanted a magic circle that could effectively and continuously run for a long time, but after studying for a month, it had gone from only about thirty seconds at the beginning to more than three minutes now, which was already a big improvement.

But this little progress is of no use to them.

Scientific research takes a lot of time and energy, and sometimes the results are often not satisfactory, and the results of scientific research are not achieved overnight.

Everyone understands this truth, but the current problem is that the material of the copper wire itself is insufficient, once it is energized, the magical nature of the copper wire will change, and it is easy to be eroded by magic.

When eroded by magic, the physical properties will change due to a chain reaction, and then the copper wire will fuse.

After the copper wire was fused, the magic circle naturally collapsed, and if it hadn't been for the protective spell that had been set up a long time ago, maybe there would have been a wind of magic in this laboratory.

When Ziegler heard about this phenomenon, he ran over and begged to join the team, and even left "Complex Variable Functions" behind.

It was so interesting for him that he had predicted that if this kind of thing could be mass-produced, the world would be turned upside down.

The red dragon frowned, pondered for a while, and then suddenly proposed, "Why don't we reduce the efficiency of the copper wire to attract mana?"

"But can this still form a circle?" said Latinia with worry written between her brows.

Hearing this proposal, the maid thought about it in her mind for a moment, then raised her eyebrows and nodded happily, "Yes!"

"The magic power is related to the strength of the magic circle, and it is related to the strength of the spell, but as long as there is a certain amount of magic power, then the magic circle must be formed!"

After explaining to Latinia, the maid turned to her and ordered, "Seth, take out the prototype and make a new mold according to the picture I will give you." ”

They don't have time to go to the factory to make new molds, so the molds used in the lab have been made by Cervantes lately, and he is the only one who has this level of processing technology...... Or rather, 'power' and 'control'!

The so-called 'prototype' is a piece of steel, Cervantes condensed the fire element on the tip of his index finger, and the sharp nails immediately sank into the steel, and compared with the images in his memory, little by little on this piece of steel.

When the 'mold' was made, the black dragon pressed the copper wire into the mold, and it took only seven minutes to complete a new circle composed of copper wire.

Even though she had seen it a few times, Latinia couldn't help but look strange when she saw Cervantes carefully take out the copper wire circle.

This black dragon had this level of control and power, otherwise, they would probably have to live next to the forge.

Cervantes put down the copper wire circle and connected the wires at both ends, so that the copper wire formed a closed loop.

The circle in front of me obviously has some more structures that seem to be more cumbersome, this is clear at a glance, and you don't need to ask to know that those cumbersome structures should be used to reduce the attraction of the magic circle.

"Electrified. ”

At the sound of a reminder from the maid, Cervantes picked up his pocket watch and remembered the time.

The electric current passed through the copper wire, and the circle was activated in an instant, and the four people present could feel that the magic power was converging towards the copper wire circle.

A breeze appeared in the center of the circle, and the maid bowed slightly, it seemed that the circle was still functioning normally.

When the magic power was about to penetrate into the copper wire, it suddenly became blocked, and when it was reflected in the perception of the four people, the speed of the magic power gathering was much slower than the previous magic circle.

Especially in the magic vision of the red dragon and the black dragon, they can clearly see that the 'volume' of magic power gathered has decreased a lot.

If it used to look like a cloud, now it looks like a mist, and the effect is very obvious.

The 'mist' shrouded the Copper Circle, and Cervantes and Ziegler carefully observed every part of the Copper Circle.

If it was the previous ones, then after two minutes, they could almost see the 'circuit breaker', but now the time has passed-

"Five minutes. Cervantes reminded softly.

The seconds and minute hands were constantly turning, and Cervantes' hand holding the pocket watch could even feel the internal gears turning.

"Six minutes!"

Even Cervantes couldn't help but get excited.

This circle has been held out until the sixth minute, which means that this method has a certain viability!

It's a pity that at this moment, a "stab" sound sounded in their ears, and the four people who had just become excited sighed because of this voice.

Failed......

"It's an overload ......"

Ziegler didn't even need to check it, Ziegler had already said the reason for this failure, "Although the circle was able to operate normally for six minutes, there was a problem that we were not aware of before this - the magic that lingered next to the circle not only activated the circle, but also strengthened the current, so this time, it was because of an overload." ”

"'Overloaded'?" muttered the maid, her brow furrowed slightly.

This is a difficult problem, if it is a problem with the circle, they can continue to modify it, but if you want to make a circle with copper wire, then 'electricity' is a necessary condition.

However, the current situation shows that copper wire may not be a particularly good material.

Although the price is low, once an overload occurs, the circle will collapse, and the mana booster will always exist, and as long as the circle continues to operate, then this situation will get worse and worse until the circle is 'overloaded'.

Although it would be a good idea to use this principle to make an electromagnetic gun, they are now making products that can be used in daily life, not cutting-edge weapons.

I'll talk about the electromagnetic cannon later, but now let's think about the situation in front of us!

The four of them were lost in thought, and the laboratory fell silent as they all looked at the destroyed circle in front of them, silent.

"Or ...... Replace it with something else?" Latinia tried to make a suggestion.

But as soon as she finished speaking, the maid shook her head, "It's not suitable, the price of other materials is a bit high in this era." ”

"I've got a way to do it!"

At this moment, the black dragon suddenly screamed, startling Latinia and the maid.

"If the current keeps increasing, won't we be able to drain the 'redundant' current?" (https:)
