The strange metal that had been knocked down was hurriedly transported to the blacksmith's shop.

Since there was no concrete plan, Robier just tried to melt the metal block.

"Being able to transmit energy, this thing is kind of like, wire?" That's right, it's wire, but the wire transmits electricity, and this metal can transmit all kinds of energy.

The fighting spirit of the knight and the magic power of the magician, if these two things are classified into the same kind, it is the energy in the crystal nucleus of the demonic beast.

Both knights and magicians rely on the Monster Crystal Nucleus to replenish them.

"Export the energy in the Demon Beast Crystal Nucleus? Lydia looked at Lei Zhe strangely, she didn't quite understand what Lei Zhe meant by asking this question.

"No, I mean that the magic of the Demon Beast Crystal Nucleus will be automatically released through manpower. Lei Zhe shook his head, rarely looking at Lydia in front of him seriously.

"Think about it. Lydia was silent, carefully recalling the books she had read, she was still very good academically, at least a scholar-level existence.

"It's okay to use the magic array, the recovery tower of the magic academy, and the mage towers in various cities, don't there be magic arrays, and the magic power in the crystal nucleus of the magic beast is stimulated through the magic array, and then it fills the air for the magician to quickly absorb and restore the magic power. ”

"Hey, why didn't I think of this problem, it can indeed be like this, as long as the magic power in the crystal nucleus is attracted through the magic attraction array, and then people can absorb it. Lydia laughed, not caring who came up with the answer first.

"But why are you asking this? Do you want to build a recovery tower here? I don't think it's necessary, you don't have many knights under your command, and it doesn't make much use of building this recovery tower. Lydia looked at Reich strangely.

The reason why Lei Zhe asked this question was nothing more than to let Erin have better conditions for learning magic, but with Erin's current strength, there was no need for this.

"Is there a way for you to make such a formation?"

"You want me to portray a magic circle, that's not a simple matter, anyway, I only have the obligation to teach Erin and Lilith magic, but not to help with coolies. There was a hint of cunning in Lydia's eyes.

Lei Zhe understood very well what this woman wanted and said directly: "As long as you can make it, you can directly open a price for how many gold coins." ”

"200 gold coins, not one less boy!"

"Okay, let's do it now!" Lei Zhe heard that two hundred gold coins were not much, and he directly agreed within the acceptable range.

Seeing Lei Zhe so refreshing, Lydia felt as uncomfortable as eating something disgusting, the price was going to be lower, and seeing Lei Zhe's appearance was obviously higher, the price would agree, for her lack of money, it was a blood loss.

But the price has already been agreed, and she is not a person who likes to go back on her word, so she can only acquiesce to this price.

"Now, have you seen everything?"

"How to build, you just say the design drawings, as for the size, make it as big as possible. ”

"Easy, you just need to ......," Lydia pointed to the side, and Lei Zhe drew the design drawings.

This is a cylindrical magic gathering tower, because of the special requirements of Lei Zhe to close the entire tower, around the tower needs to build a dark room to store the magic crystal nucleus, the formation will transport the energy in the crystal nucleus to the magic tower in a special way.

In this way, the magician in it can meditate in it to improve their magic strength and get the supplement of magic, this recovery tower is not uncommon in the magic academy, and its structural principle is also very simple.

Needless to say, since she could do it, Lydia was immediately assigned to work as a coolie in the magic tower, for which Lydia regretted very much that she did not ask for more money, because the weather in Turku was really not something that people could bear.

"You try to transfer the fighting spirit into it now. ”

Colmar nodded, picked up an iron rod made of special silvery-white metal, and began to release Dou Qi, the silver-white metal began to light up after absorbing Dou Qi.

A puff of white gas began to bubble out from the other end, visible to the naked eye.

"Fighting spirit?" Colmar was stunned, it really came out from another direction, which Lei Zhe could also see, but Lei Zhe also noticed that the surface end of the metal was also emitting white gas.

The point of release of vindictive energy is not and concentrated.

It's like a leaky wire.

"You're trying this. ”

Colmar took an iron rod and injected Dou Qi into it again, and white Dou Qi came out again from the other end.

"My lord, is that one in the iron bar?"

"Well, you guessed it right, I heard you say that iron can block and contain Dou Qi, which is why your iron sword can gather Dou Qi and slash it out. Lei Zhe nodded and said.

The silvery-white special metal will have some leakage when absorbing energy, which is naturally a waste, but after wrapping a layer of iron, this problem will be blocked, because iron can absorb energy into it, and the energy absorption ability of iron is very strong, and it is impossible to penetrate the surface of iron at that leakage speed.

But the energy is released from the other end, and the iron will reverse-feed the energy back.

It's a bit of a waste of resources, but it's a viable approach at the moment.

There are other ways to block the energy of the magic crystal nucleus, and the energy is not offensive power, and it will only be condensed into a special killing move in the hands of a mage or rider.

Energy is like water, sealed without leakage.

"Rober, now I give you the only task to find a way to make the iron pipe thinner in this way, the finer the better, and there is no need to consider whether it is strong or not. ”

Robbiel nodded, just melt and condense the filament, and then wrap it in molten iron, which is not too rare, but it is relatively slow to produce.

Everything was on track, and Lei Zhe waited for the development with peace of mind.

"This is a simple light magic array, this is heated, this is ice, this is water......"

Lydia pursed her sexy red lips, although she was a little dissatisfied with Lei Zhe coming to class, but there was no way for people to learn or refuse, not to mention that she was very accomplished when she watched the three students stunned and listened very carefully.

In the school is a place where strength is recognized, as a magician, she is not good at fighting, and she has no money to engage in scientific research in alchemy, so she quickly left the magic academy.

After a few years of wandering, she didn't make much money, her strength was too weak, and the mercenaries didn't like to team up with her.

"Why are you so interested in this? Lilith looked strangely at Lei Zhe, who was taking notes seriously.
