"The hardness of those stones is remarkably high," Chu Tianjiao said. "When that sailor's steel saber hit the ground, it made a sound like metal clashing. That sound startled everyone. Sasha picked up the blade and actually saw a fine but distinct crack along the edge. When I went to examine those white stones, I couldn't find a single nick or even the slightest trace of an impact."
"An intensity that can shatter a steel saber without leaving a scratch?" Chu Zihang frowned slightly. "And it's a pure white solid. Does such a substance even exist in nature?"
"It might not exist in nature, but it's nothing unusual to find such things inside a Nibelungen," Chu Tianjiao said in a low voice. "Those crew members seemed to have some method of roughly measuring it; the hardness of those stones was almost comparable to diamond. Some of them were very interested in the stones on the island. Bringing this kind of unknown stone material out could fetch a huge price. But I knew we had no time to waste, so I urged them to move on. Our primary mission was to climb the altar on the island, but even that wasn't our ultimate goal. I knew I had to climb to the very central island; I had to see that white humanoid wrapped completely in bandages, face-to-face. That was the obsession that drove me to risk my life and enter this Nibelungen."
