The silence lasted for quite a while. In the end, Si Long, standing beside them, broke it and asked Huo Yuhao, "What kinds of rare metal ore do you need?"
Huo Yuhao casually listed a few. Si Long thought for a moment, then shook his head. "We can't do it. Even all of Gengxin City doesn't have reserves that large. If it were just iron essence or other metals that aren't particularly rare, perhaps we could scrape a batch together. But the kinds you want are too high-end, and the quantities are too large. And you need a continuous supply... I don't think any power on the entire continent can meet your needs."
Huo Yuhao's heart sank at that. What he had just listed were only some of the rare metals essential to making Class 5 and Class 6 Soul Tools. Huo Yuhao understood one thing clearly: the development of Soul Tools could not be separated from rare metals.
Although Lou Gao's smelting technique could make up for some of the shortcomings in this area, it was not mature, and Huo Yuhao would not be able to use it anytime soon. Moreover, Huo Yuhao knew that once he began promoting Soul Tools, he would definitely have to make high-grade ones. They would even be his focus in the short term.
Although low-grade Soul Tools did not require high-quality metals, their uses were very limited. If Huo Yuhao only promoted low-grade Soul Tools, then as time passed, Soul Tools would ultimately be reduced to dispensable toys.
Moreover, Huo Yuhao's goal was to root Soul Tools in the hearts of the people of the Douluo Continent, allowing them to continue developing. That meant high-end Soul Tools were essential.
Although Soul Tool technology could develop slowly, if the Douluo Continent could not even
