I don't know if it's because Luo Xiu carries a Buff that increases comprehension ability by 10%, so he has such a powerful divergent mind, and in the originally inconspicuous earth magic, Luo Xiu found a path to success.

It didn't take Luo Xiu too long to learn the low-level alchemy, and after two days and one night, he could skillfully turn a stone into gold.

Although with his level of magic, he could only change a very small amount of gold, but it was enough, he just wanted to figure out the mechanism of this spell.

In the process of casting spells, Luo Xiu always carefully perceived the changes in matter, at first he couldn't perceive anything, just watched the stone change, but after many exercises, Luo Xiu began to feel the doorway.

The stone itself contains metallic elements, but it is more silica, and after casting the spell, Luo Xiu gradually captured the transformation of silica into metallic elements under a certain action, and then formed oxides of gold, copper and iron.

I don't know if it's because Luo Xiu's mana is limited, or because the spell itself is flawed, the purity of the gold made of "turning stones into gold" is not particularly high, and there are a lot of impurities in it.

But Luo Xiu didn't care about this, as long as he could point out the gold, he was already very happy.

And since it can turn rocks into gold, it is natural that rocks can also be turned into other substances.

The third time Luo Xiu asked Malfoy to borrow all the earth-based magic books, and he wanted to continue his studies in this magic.

……

As he studied magic and science, he used fire magic to transform several of Hagrid's carpentry tools into electrician's tools, and also fired a crucible.

At the same time, in order to prevent Quirrell, possessed by Voldemort, from attacking Hagrid, Rosho carried a wand to accompany Hagrid to patrol the Forbidden Forest every night.

In fact, Quirrell tried to ambush Hagrid several times, but eventually retreated, Hagrid mocked him as a "cowardly poacher", and Rosho knew that Quirrell must be hatching a conspiracy.

With Voldemort behind the scenes, he and Hagrid were not destined to have a good time.

Therefore, the plan to build the Ark Reactor is particularly important.

A week later, the diligent Luo Xiu had a reward.

Earth-based magic became the second sub-discipline to be promoted to level 2 by Luo Xiu after light magic, and after level 2, Luo Xiu's mastery of alchemy reached a higher level.

He had already figured out the laws of alchemy, and knew how the spell could change matter on an atomic level.

And as long as he concentrates on imagining the microstructure of other elements while casting the spell, then he can transform oxygen and silicon into the metal elements he wants.

Fortunately, Luo Xiu, who has a certain foundation in chemistry, is very familiar with the atomic structure diagrams of the various elements he needs, which makes him play a role in the field of earth magic.

The first is the lead needed to prepare the battery - Luo Xiu stared intently at a stone in front of him while casting the spell of "turning stones into gold", but at the same time, what appeared in his mind was a diagram of the atomic structure of the lead element.

"A little stone into gold!"

A flash of light flashed, and the fist-sized stone changed, and in that instant, the space around it seemed to begin to collapse.

Immediately after that, the stone turned into a lead block, and Luo Xiu shouted excitedly!

"Great! I'm going to have a battery! ”

According to the same method, Luo Xiu "transformed" the materials needed to prepare the battery one by one, in fact, this is a material conversion, but the mechanism of its conversion is still unknown.

Luo Xiu's magic level is limited, and the number of materials he can convert is also limited, but fortunately, whether it is to prepare the battery or the Ark Reactor, Luo Xiu does not need many materials - he only cares about whether the composition of the material is pure enough, not whether the number of materials is enough - earth magic can just meet him.

The next step is to prepare the battery, and Luo Xiu forged the components needed for the battery step by step.

Plates, lead parts, cluster boxes, comb plates, electrolytes, caps......

Hagrid, who had never seen these things, was dumbfounded, he thought at first that Luo Xiu was making a delicate lunch box, but after seeing it, Hagrid understood that what Luo Xiu was going to do was far more complicated than he imagined.

"What the hell is this? Repair. Hagrid asked as he paced over from time to time, drinking mead.

"It's a battery, a powerful battery." Luo Xiu said with a smile.

Still incomprehensible, Hagrid shook his head and walked away.

Finally, three days later, the battery was finished.

Luo Xiu dragged it to the door of the cabin and began to charge it.

"The energy from the thunder magic can finally be stored." Luo Xiu said happily.

"Lightning and thunder!"

As the incantation was pronounced, a dazzling thunderbolt shot out from the tip of the wand and struck directly at the battery that Luo Xiu had prepared himself.

The storage is complete - the next step is to put it into the production of the Ark Reactor.

And once the Ark Reactor is built, the entire Hogwarts will have no power to match it.

Looking at the direction of the Forbidden Forest, Luo Xiu was full of ambition.

"Voldemort, if you had received a boxed lunch in the first part, would the whole Harry Potter world become more interesting?"

——————

Hagrid was shocked by the appearance of the battery, and he never imagined that wizards could store the electricity generated by magic.

Fortunately, Hagrid was a simple and honest man, and did not report Rosho's invention to Dumbledore, otherwise, the Ark Reactor plan would have been stillborn.

In the following period, Luo Xiu began to develop magic and technology.

In fact, the more Luo Xiu learned about magic, the more he found that magic and technology have a lot in common.

The reason for this is that the two are probably the same thing in themselves.

Technology is a technology that human beings first grasp the principle and then deduce, while magic is another technology that human beings skip the principle and master through the accumulation of experience.

The Ark Reactor is being made in an orderly manner, and at the same time, Luo Xiu is also considering what kind of weapon he wants to use the Ark Reactor to make.

The world of Harry Potter is still different from the world of Marvel after all, and the weapons here also need to take into account the attack of magic.

During a chance reading, Rosho found a popular science book called "What Fantastic Beasts Are Afraid of" from one of Hagrid's few surviving books, in which the learned author mentioned that many magic spells would fail when they encountered a metal like silver.

"Anti-magic metal" - this is how the author describes silver, which also gave Luo Xiu a revelation.

If you want to fight Voldemort, or most of the enemies in the world of Harry Potter, the core is to defend against their magic.

And since there is anti-magic metal in this world, once a set of armor made of anti-magic metal is created from the Ark Reactor, Voldemort will become no threat.
