After the mysterious cloak man Mobius left, Rosen took out all the materials and placed them on the table in the alchemy room one by one.

The materials were very complicated, including a large piece of brass, a fist-thick block of graphite, some dense papyrus, a small puff of refined flour, a large piece of pure quartz, and a precious ebony stick, etc., all in total, more than twenty things.

Veronica looked at this, touched that, and asked, "And then, you use these things to tame thunder and lightning?" ”

Rosen shook his head: "No, not to tame, but to make a battery." In my battery, it was filled with thunderbolts of a docile nature. ”

"Electric ...... Battery? ”

This time, Veronica and Anne spoke almost in unison.

The reaction of the two women was not unexpected by Rosen, for earthlings, chemical batteries are commonly used daily necessities, but for people in other worlds, 'battery' is completely unfamiliar words that have never been seen before, and it sounds like Rosen created it.

Rosen thought for a moment and tried to explain: "Uh~ I ask you, Mustang is generally very irritable, right? ”

"Of course." Veronica nodded.

"But if you put a wild horse in the stable and raise it for a while, it really can't be bred for a few generations, and the wild horse will definitely become a domestic horse, and its personality will become more and more docile, right?"

Hearing this, Anne thought she understood, and she said, "You mean, you want to catch the wild thunderbolts and domesticate them?" ”

"uh~~~"

Rosen couldn't really evaluate Anne's ability to associate, so he smiled wryly and said, "Pretty much the same thing." Let's put it this way, the 'battery' I call is equivalent to a stable, which contains not wild thunderbolts, but domestic thunderbolts, and its character is extremely docile, even if you touch it with your hands. ”

Hearing this, Veronica slapped her palms and said with a light smile: "Interesting, very novel statement, very intriguing, if you say it to ordinary people, you can convince the other party at once." ”

"You don't believe it?" Rosen asked with a smile.

Veronica pouted at the material on the table, "Unless you make this battery, what you say is out of the blue, and it's no different from fart." ”

Rosen looked at Anne again: "Anne, do you believe it?" ”

"I ...... I don't know. Anne looked dazed, she had actually been persuaded by Rosen, but Veronica was not wrong, so she was confused.

Lawson looked at the materials and fiddled with them, but suddenly shook his head and sighed.

"What, Lu? Don't forget, you and Morbius have a pact. Veronica raised an eyebrow.

"It's not." Rosen picked up the brass block on the table and said, "Look at this piece of brass, it actually contains two basic elements, namely copper and zinc. I need zinc to make a battery, but now I don't have a high-temperature stove to melt this brass. With my ability, it is not possible to separate the zinc directly from the brass block. ”

In brass, there are very strong metal bonds between various metal atoms, and with the ability of his current two-layer electromagnetic sickle, although he can barely separate some zinc elements, the efficiency will be very, very low, and it will not meet the requirements of use at all.

didn't think about it, but Veronica smiled slightly: "It's simple." ”

Before she finished speaking, she picked up the big brass block on the table, and a pair of white and smooth hands held the brass block, and then rubbed it back and forth, the hard brass became as soft as mud in her hand, and the boxy brass block was suddenly rubbed into a brass stick.

"~~~" Rosen's eyes widened, this hand 'holding copper into clay' means is really shocking.

"Celestial!" Anne's body tensed up, and the power was far beyond her limits, it was terrifying.

Veronica didn't notice it, her hands kept rubbing, rubbing, and squeezing back and forth, and the brass blocks quickly changed shape in her hands, first into sticks, then into balls, and then into irregular lumps of mud.

Under the pressure of such violent force, the temperature of the brass block rose rapidly, and the texture became softer and softer, and after about five or six minutes, a drop of brassy liquid that glowed red dripped from between Veronica's fingers and landed on the wooden tabletop, making a 'snort' sound, and a large cloud of green smoke came out.

Rosen looked at Veronica's hand again, it was still white and delicate, and the brass juice with a temperature close to 1200 degrees couldn't hurt her hand, which ...... What a strong flesh this is.

Veronica suddenly asked, "Is this enough?" ”

"Enough! That's enough! ”

Lawson immediately activated the power of alchemy, wrapped the hot brass juice in Veronica's hand, and then began to purify it.

This piece of brass, with a total weight of about 4 kilograms, of which about 30% is metallic zinc, which is lifted in liquid state with Rosen's current strength

Pure, very relaxed.

In just five or six seconds, the liquid brass in the air split into two pieces, one purple-red and the other blue-gray.

"Fuchsia is pure metallic copper, and the blue-gray piece is the metal zinc I need, and it is also one of the important raw materials for batteries." Rosen explained.

Anne looked at the copper, and a little star flashed in her eyes: "I really didn't expect that pure copper would be so beautiful." ”

Rosen smiled slightly, and with a movement of his mind, the high-temperature copper water in the air was divided into two pieces, one large and one small, the large one did not move, and the small one of the irregular spheres slowly transformed into a model of a pistol with a precise and domineering shape.

Immediately after, the blue-gray metallic zinc quickly unfolded and flattened into a piece of metal resembling parchment.

After doing this, Lawson waited for the two pieces of metal to cool down, and his mind moved slightly, and the pistol model flew towards Anne: "Give it to you." ”

"Mine? Thank you! Anne was pleasantly surprised. She could see that it was a kind of musket, and looking at this shape, it was more beautiful than her destruction of the world, and the whole body was glowing with a purple-red metallic luster, and she liked it at once.

Rosen was not idle, he put the zinc skin on the table again, and then began to toss the graphite blocks on the table, the graphite is soft and easy to process, and in a short time, Rosen got several slender graphite pillars.

Then he began to fiddle with the refined flour again, blending it into a paste and adding a few strange things to it.

Veronica couldn't read at all, and she couldn't help, all she could do now was watch.

About 1 hour later.

Rosen let out a long breath, and in front of him, there were several more short and thick cylinders, the periphery of the cylinder was wrapped in very dense papyrus, and the paper was soaked in wax oil, and the ends of the cylinder were shiny copper sheets, which looked very peculiar.

Veronica, like Anne, had never seen anything like it.

"This is the battery?" Veronica asked.

"yes, that's the battery." Lawson nodded.

As long as there is an electrolyte as a medium and two metals with different activity as the poles of the battery to form a circuit, it is a galvanic battery. In fact, just inserting copper and iron into a potato forms a 'potato' battery.

His current battery is made in imitation of the earth's zinc-manganese dry battery, with only a few minor changes. It's not that other batteries can't do it, but zinc-manganese dry batteries are mature products with simple structure and relatively stable performance.

"There's a tame thunderbolt in there?" Veronica looked at her unsightly battery with a look of disbelief.

"Yes, I don't believe it."

Lawson used scissors to cut an extremely fine zinc wire from the zinc sheet, and directly shorted it on the positive and negative poles of the battery, and in an instant, the zinc wire turned red, shiny, and fused.

The whole process took less than 3 seconds, and what happened was not earth-shattering.

However, Veronica was stunned, speechless.

Anne reached out to cover her mouth, looking incredulous.

For a long time, Veronica looked at the battery on the table with a look of awe, pointed to the battery, and said humbly: "No, this is definitely not a battery!" This is a cage of thunder and lightning! It must possess terrifying magical powers, otherwise it would never have been possible to tame thunder and lightning! ”

Lawson was speechless: "......."

This is just a dry battery, 2 yuan a section in the earth supermarket, as for it?

Anne was also shocked, she didn't look at the battery, but at Lawson, the maker of the battery, and didn't speak, just looked at him with a look of adoration.

Both Veronica and Anne are well-informed people, and now, they are all shocked like this.

Just looking at the reactions of the two women, Rosen felt that the so-called flash wand he was about to build was difficult to sell for a lot of money.
