"There is another problem," after a long period of silence, Sara suddenly spoke again, "to make the currency we'll need to melt down the ores. How can we do that with such ore?"
"Melt them down?" This time Arthur was surprised by this small yet great point.
"Currencies are like a blacksmith, making them required to melt the ores into liquid."
"…"
This time Arthur had zero clue about what to do. These ores were explosive. If they were exposed to such intense heat, they would instantly explode.
However before he could rack his brain about it, the answer came from his system.
'Ding! Why not ask the originals themselves?' the system proposed, 'Ding! After all they are the ones knowing everything about this ore.'
Arthur found this idea appealing, however he didn't try to go inside his world and ask the originals about that.
They were travelling far away from his main cities. They came across a few cities under construction, but they just passed fast on the heads of those working diligently to build them.
Besides he was quite sure this wasn't the only problem he had. He would prefer to give Sara more time to reconsider the entire process of casting a currency before asking the originals.
And his hunch was proven right.
After five hours of constant flying in silence, Sara spoke again.
"The currency needs something to hold value to."
"What do you mean? Like energy or power?" Arthur didn't get her meaning and he had the right for that. After all, this currency concept was alien to his former life as a cultivator.
The only currency in the cultivation world was spiritual energy and power.
"I know this ore is unique and quite rare," she said, trying slowly to explain things to him, "but that doesn't mean it holds any value on its own. We need something precious, something everyone in the entire universe knows its value and appreciates."
"Like what?" Arthur got her meaning by now but he couldn't get any idea about that matter.
"It's not the problem of selecting such a thing, but it's also about how to incorporate it with that ore of yours," Sara threw the ores she was holding in the air before adding, "such process requires ores to be compatible with each other. It's a complicated process with a high margin of failure."
"…"
As the last time, Arthur didn't have anything to say to her except for his silence. But she didn't stop there.
"We also need to establish an easy protocol to cast our currency, but we need to keep it strict and secure," she paused before adding, "if others knew about our process, they would easily dispatch troops here and control many ore mines. After all, this ore is abundant in this world, right?"
Just before Arthur could say anything to her, the sky suddenly dimmed.
"What's going on?" Sara felt some fear while Arthur remained silent. Yet his face showed a change the moment he spotted what caused the sky to dim at such midday hours.
It was like another sun appeared in the heart of the sky. But it wasn't just one. In Arthur and Sara's eyes, many bright purple dots appeared coming fast from the space.
"Come inside, now!" Without any hesitation, Arthur made Gege summon a portal before literally pushing Sara inside. The latter felt more panic from his actions.
However the moment she saw his face, she was puzzled. He didn't have any sign of worry or fear like her; his face showed only excitement.
That was weird to her. But for Arthur this was nothing. He was very thrilled the moment he realized what was going on.
"It's coming," he raised his head high in the sky while holding a dark fabric in his claws. It was that dark curtain that could protect anyone from the purple fire.
As for these little stars falling fast towards his direction, they were nothing more but the purple ore. This scene was what he heard about before, the falling catastrophe of the purple fire.
Luckily it fell in a place between his cities. He didn't want his new cities to get damaged.
"They came without warning or signs, right?" he tried to assess this phenomenon and see through it.
'I didn't see anything weird,' Gege said.
'I didn't feel anything strange,' the golden dragon said.
'Ding! Everything looked perfectly fine before these little stars appeared in the middle of the sky,' the system added.
"So there is no way to cause them to fall, or control their trajectory," Arthur felt some disappointment there. He thought he would figure out the way of bringing down these ores and controlling their landing location.
But now he realized he was fantasizing about this. However, just before he could lose all hope, a change occurred in his eyes.
A strange flash was spotted in the ground. At first he couldn't see it clearly amidst the bright sunny day. But when the light coming from the sun clashed with the light coming from the falling ores, the world looked darker.
"What is that?"
It was like a ray of faint green and blue light emanated from the ground. It formed a small arc that didn't exceed ten meters at most. It looked like a rainbow, but with green and blue colors only intertwining together.
"Can you tell the landing spot of the ores?" Arthur hurriedly shouted while falling fast towards the ground. He felt something was linked to these strange rays, but he wanted to make sure first before he got his hopes high.
Gege didn't delay to calculate the falling spot and compare it with the rays on the ground. She could already read Arthur's thoughts and could tell what he wanted.
'They will fall on that spot,' she said after confirming it more than once.
"Sure?" Arthur asked before landing just near that spot.
'Absolutely,' Gege's answer was decisive. The next moment Arthur took out his sword and activated his technique.
"Hopefully that thing isn't deeply buried in the ground," he muttered before starting to hit the spot below the ray of light.
But to his surprise his sword slashes didn't cause any damage at all! He felt weird at first before the golden dragon suggested something.
