"Right here..."
Xu Jiujiu slid her slender fingers over her ring, keeping her other fair hand clenched as she put on a mysterious expression.
"Guess what it is?"
"Arcane copper?"
Xu Cheng smiled.
"You're no fun!"
Xu Jiujiu opened her palm and said listlessly, "An underground river was discovered in southern Paro Province in the Star Luo Empire. Its bed is covered in arcane copper. According to the specialists' survey, there are at least ten tons of it."
"Ten tons?!!"
Xu Cheng was startled.
Arcane copper was tougher and more malleable than mithril. Over the past three years, it had mostly been used to manufacture Soul Tools for outer space-for instance, the Protective Cabins aboard the various Interstellar Warships were largely made from it.
It was also extremely resistant to corrosion.
Many Soul Masters with corrosive attributes had tested it, and even Titled Douluos had struggled to corrode it in the slightest.
Wang Dong'er had also said that after Spirit Forging, arcane copper became extraordinarily malleable, and its upper limits were still being explored.
Previously, they had practically dug three feet into the ground throughout the entire Sun Moon Empire, yet had only managed to scrape together two or three tons of arcane copper. This was precisely where the Interstellar Warship Plan had hit a bottleneck...
With these ten tons of arcane copper, the road ahead would be wide open!
"Not bad, not bad!"
Xu Cheng raised his eyebrows.
"What reward do you want?"
"Mmm... let's do it again." Xu Jiujiu had long since tossed her older brother's instructions to the back of her mind. She hooked her fair, delicate arms around Xu Cheng's neck and breathed into his ear.
Xu Cheng: "..."
Fine, as you wish!
He immediately leaned over her.
Once again, decadent sounds drifted through the hotel...
