Yan Fei hadn't expected Yang Qi to give him such a huge surprise, developing an unprecedented type of steel cement using the discarded and useless underground rocks. As long as this steel cement could be popularized globally, Dream Island would see a massive influx of wealth.
After all, the total amount of iron ore in the world is limited, and iron ore is expensive. Once Dream Island's steel cement hits the market, as long as it is reasonably priced, it will immediately seize a large market share originally belonging to iron ore. From this perspective, beneath Dream Island lies an iron ore mountain, a super mine that is a billion times larger than all the iron ore deposits on Earth combined.
Yan Fei immediately asked the most critical question, "What's the production cost of this steel cement? Does it exceed the mining and refining costs of iron ore?"
