Zhou Shu thought that he had overestimated the mineral reserves here, but he realized that he had still underestimated them.
With the efforts of hundreds of miners day and night, the few warehouses that had been prepared were quickly filled.
Thousands of kilograms of various materials were piled up in a mess.
In the end, Zhou Shu and Shi Songtao felt numb about it.
The lack of manpower became apparent again.
Shi Songtao was the only one working on purifying the ore. Even if he had temporarily mastered the Iron Smelting Hands Technique, there was only so much work he could do alone.
He was not nearly as fast as miners could dig.
Zhou Shu didn't care much about purifying the ore.
In any case, he could slowly purify it in his own camp. If it didn't work, he could just bring the ore back to Great Xia.
