Anyone who has studied chemistry knows that silver is a metal that is very easy to replace, whether it is aqua regia or nitric acid, it can be easily replaced. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

But Lake does not have nitric acid on hand, and without nitric acid, there is naturally no way to configure aqua regia, after all, aqua regia is made of aqua regia is a mixture of 1 volume of concentrated nitric acid and 3 volumes of concentrated hydrochloric acid, but don't forget that the melting point of silver is very low, only 900 degrees Celsius (at room temperature), so Lake and Elaine plan to directly melt the silver in the black iron gold ore.

This is not a problem, especially after Lake has a witchcraft oil lamp in his hand, the oil used in this oil lamp is a thing called black crude oil, which is black, and the temperature can reach 1000-5000 degrees Celsius when ignited, so it is still easy to use it to melt silver.

Moreover, the melting point of black iron gold is much higher than that of silver, and it does not change even at a high temperature of 3,000 degrees Celsius.

Something that can already be used to make magic weapons with black iron gold, if it melts at a simple temperature of 100 degrees, then when the time comes to take this kind of magic weapon to fight, isn't it too bad?

A random fire witchcraft on the other side came over, and I saw that my magic weapon immediately melted into iron juice, and that kind of scene was simply not too sour.

Because Lake's sorcery oil lamp is not large, it took Lake and Elaine three days to melt all the silver.

It took more than three days to finally melt all the raw ore one by one, and instead there was an extra lump of black metal in the hands of Lake and Elaine.

The only difference is that the black metal in Lake's hand is the size of an adult's fist, while Elaine's is only half the size of a child's fist......

When Lake and Elaine finished distributing the black iron gold, they began to loot other resources.

......

One day, Ryker and Elaine were collecting a red fruit, which can slightly enhance the strength of a person's body after eating, and just after the collection was completed, Lake's face suddenly changed, and he took out a crystal ball in his hand, on which Orison's cold face appeared.

"Lake, you hurry back to the base now, I've already sent you the coordinates!!" Orison's face was a little gloomy, and Lake could even see that Orison's finger bones were a little white as he held the Blood Spirit Witch Staff.

"Yes, Mentor. Lake didn't hesitate and immediately agreed.

"Looks like something bad has happened!!" Lake had a faint feeling in his heart.

"What's wrong with you?" Elaine next to her also noticed that Ryker's face was a little wrong at this time, and asked.

"Elaine, my mentor summoned me to go back, do you want to go back with me now, or continue to search for resources?" Ryker asked with a glance at Elaine.

"The resources in my hands now are almost enough for me to be promoted to a third-level wizard apprentice, and it's also very dangerous outside, I don't want to risk it, so I plan to go back with you. Elaine's face turned a little red, in fact, the world of the Frogmen had completely fallen a few months ago, and the Frogmen world had completely become a colony of the Wizarding Academy of the Tower of Black Rope at this moment.

Tens of thousands of resources are now being transported to the Tower of Hesso's Wizarding Academy.

And those demon frogmen have become a group of precious slave resources in the hands of the Wizarding Academy of the Tower of Melinace.

After all, the Devil Frog Man is also a sub-human no matter how it is said, and he also has intelligence, and even these Demon Frog People can also do witchcraft, which is simply the most ideal slave (except that they are too ugly to meet the aesthetics of human beings at all). But in any case, the slaves of the Devil Frogmen are already very good.

Lake glanced at Elaine with a smirk, but didn't expose her lies, and returned to the base with her.

The so-called base is a floating island that comes across the border, temporarily serving as a base for this expedition to the other world.

When I returned to the base, I could see a huge floating island with a diameter of more than 50 miles floating in the sky, a "ladder" hanging down from the island, and many puppet slaves were constantly transporting some goods, from the world of the Frogmen to the Wizarding Academy of the Tower of Hessor.

Lake tugged at his black Cloak of the Slayer, the silver-white Pretender mask on his face glowing strangely in the sunlight.

"Let's go up!" There were no wizard guards on the "ladder" leading to the island, only two sculptures that looked like them, and the intellectuals didn't recognize what they were.

After the sculpture was shown in front of the statue, the token of the Wizarding Academy of the Tower of Black Rope was revealed, and then Ryker and Elaine easily climbed this "ladder"!

After arriving on the floating island, Elaine said goodbye to Ryker, and she went to find her mentor, Frynn.

And Lake, under the guidance of the crystal ball, soon found the address of his mentor Orison.

As the official wizard of the Wizarding Academy of the Tower of Hesso, Orison's treatment is not bad, at least he has his own fixed den on this floating island......

This floating island is really big, there are a lot of people, the island is bustling, most of them are wizard apprentices, and the meaning of doing business here is woody!!

Looking around, there are more than n people setting up stalls on the entire island, and after a closer look, Lake found that most of these things are the original products of the Devil Frogman world, and after these wizard apprentices harvest them, they can't use them themselves, and then they simply take them here to sell them.

With a casual glance, Lake found a lot of good things, but Lake didn't stop, but instead accelerated his pace, no matter what, he still had to find Orison first, and then see what went wrong.

Thinking of Orison's dead face, Ryker's body trembled, that is his mentor, his own backer, if Orison is mad and ignores Ryke, it will not be good for Ryker to mix in the Wizarding Academy of the Tower of Hethor.

For this kind of person, how dare Lake snub?

So Lake took three steps and two steps, eager to spread a pair of wings and fly over......

Well, Lake himself has wings, it's just not appropriate to be exposed on such occasions.

I still can't walk slowly, but fortunately, Orison's room is not very far from Lake, and it is only a third of the hourglass time. Lake came to a manor.

Lake's first reaction when he saw this manor was the luxury of Nyima!

This floating island is, in general, a space fortress, a military base.

Although the space on it is not small, most of it is some weapons or something, so there is really not a lot of room to spare......
