By the time Liu Changxu stayed behind to oversee mining operations at the sun-gold iron vein, extracting the sun-gold iron had already become extremely difficult.
He therefore entered the mine himself to investigate the actual conditions. Liu Changxu discovered that his clansmen mainly relied on their own magic power, magical artifacts, and lower-grade first-tier magical mining picks to extract the sun-gold iron ore.
These had barely sufficed when mining first began, but once they reached thirty zhang underground, they encountered tremendous difficulties.
At around thirty zhang underground, the sun-gold iron ore grew increasingly high in quality, and increasingly hard as well. Sun-gold iron was, after all, a primary material for refining first-tier supreme-grade magical artifacts, so the difficulty of mining it was easy to imagine.
When a lower-grade first-tier magical mining pick struck the sun-gold iron ore, sparks flew everywhere. Before long, the pick would be ruined.
Using ordinary magical artifacts not only yielded poor results but also risked damaging those precious artifacts. For clansmen who already lacked magical artifacts, the losses far outweighed the gains.
As for using spells such as the Wind Blade Technique to mine sun-gold iron ore, that was even more difficult. Qi Refinement cultivators' spells lacked sufficient power, and mining also consumed a great deal of magic power.
Thus, the clansmen mostly mined sun-gold iron ore from the shallow layers, with no choice but to abandon the high-quality ore deep underground.
After learning the basic situation firsthand, Liu Changxu immediately gathered the clansmen involved in mining for a meeting to discuss the work.
At the meeting, Grand Elder Liu Qiusheng first gave Liu Changxu a brief account of the mining situation. "Changxu, based on our preliminary surveys and estimates, this sun-gold iron vein should be a micro vein. However, our limited abilities have prevented us
