The Last Alchemist

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

The materials are very complicated, including a large piece of brass, a piece of graphite as thick as a fist, some dense papyrus, a small pile of refined flour, a large piece of pure quartz, and a long and precious ebony stick, etc., zero to one Total, more than twenty things in total.

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

Rosen shook his head: "No, not to tame, but to make a battery. My battery is filled with docile thunder and lightning."

"Battery?"

This time, Veronica and Annie spoke almost in unison.

The reaction of the two women was not beyond Rosen's expectation. To people on earth, chemical batteries are common daily necessities, but to people from other worlds, 'battery' is a completely unfamiliar word that they have never heard of before. When I heard it, it was Rosen. Made.

Rosen thought for a while and tried to explain: "Uh~ Let me ask you, Mustang's character is generally very irritable, right?"

"Of course." Veronica nodded.

"But if you catch a wild horse in a stable and keep it for a while, if that doesn't work, just breed it for a few generations. The wild horse will definitely become a domestic horse and its character will become more and more docile, right?"

Hearing this, Anne thought she understood. She said, "You mean, you want to capture the wild thunder and lightning and then tame them?"

"Uh~~~"

Rosen really couldn't evaluate Annie's ability to associate. He smiled bitterly and said, "It's pretty much the same idea. Let's put it this way, the 'battery' I'm talking about is equivalent to a stable. What's in it is not wild lightning, but domesticated lightning." Thunder and lightning are so docile that even if they are touched by hand, they will be fine.”

Hearing this, Veronica clapped her hands and said with a smile: "Interesting, a very novel statement, very inspiring. If you tell ordinary people, you can convince them in one go."

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

Veronica pouted at the materials on the table and said, "Unless you make this battery, your talk is just like farting."

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

"I don't know." Annie looked confused. She had actually been convinced by Rosen, but what Veronica said was not wrong, so she was confused.

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

"What, the secret was revealed? Don't forget, you and Mobius still have a bet." Veronica raised her eyebrows.

"No." Rosen picked up the brass block on the table and said, "Look at this piece of brass. It actually contains two basic elements, copper and zinc. I need to use zinc to make a battery. But now I don’t have a high-temperature stove to melt this piece of brass, and with my ability, it’s impossible to directly separate the zinc from the brass piece.”

In brass, there are very strong metallic bonds between each metal atom. With the current ability of his two-layer electromagnetic sickle, although it can barely separate some zinc elements, the efficiency will be very, very low and it cannot meet the usage requirements at all.

Without thinking, Veronica smiled slightly: "This is simple."

Before she finished speaking, she picked up the large brass block on the table, held it in her hands with a pair of white and smooth hands, and then rubbed it back and forth. The hard brass became as soft as The square piece of brass, as soft as mud, was suddenly twisted into a brass rod.

"Fuck~~~" Rosen's eyes widened. This method of "turning copper into clay" was really shocking.

"God!" Annie's body tensed up. This power was far beyond her limit. It was really terrifying.

Veronica didn't notice at all. Her hands kept rubbing, rubbing, and squeezing back and forth. The brass block quickly changed shape in her hands. One moment it was a stick, the next it turned into a ball, and the next it turned into irregular mud. piece.

Under such violent force, the temperature of the brass block rose rapidly, and its texture became softer and softer. After about five or six minutes, a drop of red-glow brass liquid dripped from the gap between Veronica's fingers. It fell down and landed on the wooden table with a "chi" sound, and a large cloud of green smoke came out.

Rosen looked at Veronica's hands again. They were still white and delicate. The brass juice with a temperature close to 1,200 degrees could not harm her hands. What a strong body this was.

Veronica suddenly asked: "Is this enough?"

"That's enough! That's enough!"

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

This piece of brass weighs about 4 kilograms in total, about 30% of which is metallic zinc. With Rosen’s current power, it can be extracted in a liquid state.

Pure and very relaxing.

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

"The purple one is pure metallic copper, and the blue-grey one is the metallic zinc I need, which is also one of the important raw materials for batteries." Rosen explained.

Annie looked at the copper block, with little stars flashing in her eyes: "I never thought that pure copper would be so beautiful."

Rosen smiled slightly, and with a thought, the high-temperature copper water in the air split into two pieces, one large and one small. The larger piece did not move, and the smaller irregular sphere slowly transformed into a precise and domineering pistol model.

Then, the blue-gray metal zinc quickly unfolded and flattened into a metal sheet similar to parchment.

After doing all this, Rosen waited for the two pieces of metal to cool down, and with a slight thought, the pistol model flew to Anne: "For you."

"Mine? Thank you!" Anne was very surprised. She could see that this was a kind of musket. Judging from the shape, it was more beautiful than her Destroying Heaven and Earth, and the whole body was glowing with purple-red metallic luster. She liked it at once.

Rosen was not idle. He put the zinc sheet on the table again, and then began to toss the graphite block on the table. Graphite is soft and easy to process. After a while, Rosen got several slender graphite pillars.

Then, he began to fiddle with refined flour, mixing the flour into a paste, and adding some strange things to it.

Veronica couldn't understand it at all, and couldn't help. All she could do now was to watch.

After about an hour.

Rosen let out a long breath. In front of him, there were several short and thick cylinders. The outer surface of the cylinder was wrapped with very dense papyrus, which was soaked with wax oil. The two ends of the cylinder were shiny copper sheets, which looked very strange.

Veronica, like Anne, had never seen such a thing before.

"Is this a battery?" Veronica asked.

"Yes, this is a battery." Rosen nodded.

It's just a chemical battery. The principle is very simple. As long as there is an electrolyte as a medium and two metals with different activities as the two poles of the battery to form a circuit, it is a primary battery. In fact, as long as copper and iron are inserted into a potato, a "potato" battery is formed.

His current battery is made by imitating the zinc-manganese dry battery on Earth, with only some minor changes in details. It's not that other batteries are not good, but zinc-manganese dry batteries are mature products with simple structures and relatively stable performance.

"Is there tamed lightning in it?" Veronica looked at the unprepossessing battery with a look of disbelief.

"Yes, look if you don't believe me."

Rosen used scissors to cut a very thin zinc wire from the zinc sheet and short-circuited it directly between the positive and negative poles of the battery. In an instant, the zinc wire turned red, glowed, and melted.

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

But Veronica was stunned and speechless.

Annie covered her mouth with her hand, looking unbelievable.

For a long time, Veronica looked at the battery on the table with awe, pointed at the battery, and said humbly: "No, this is definitely not a battery! This is a cage of lightning! It must have terrifying magical power, otherwise it would be impossible to tame lightning!"

Rosen was speechless: "."

This is just a dry battery, 2 yuan a piece in the Earth Supermarket, is it that serious?

Annie was also shocked. She didn't look at the battery, but looked at the battery maker Rosen, and didn't say anything, just looked at him with an admiring look.

Both Veronica and Anne were well-informed people, but now, they were shocked like this.

Just looking at the reactions of the two women, Rosen felt that it would be difficult not to sell the so-called flashing wand he was about to make for a lot of money.
