"The energy copper content in high-energy super crystal batteries is relatively high. Calculating at an 8% ratio, this requires 80,000 tons of energy copper."
"Currently, due to the lack of energy copper to manufacture super crystal batteries, fulfilling orders has become a big problem."
Ling Shuiling already understood, "This time opening the World Gate is for mining energy copper?"
Yang Fan nodded, "Actually, a few months ago, the exploration team discovered a large energy copper ore vein, but it's buried over 3.5 kilometers deep."
"Due to the Sea of Death Black Sand being extremely dangerous, large movements while mining easily attract powerful monsters or even the Primordial Evil Race, which is why the vein couldn't be developed."
"After several months of research, the official preparations are now fully ready, so the mining of energy copper has officially started."
Ling Shuiling uttered "Oh" and asked a question, "How many tons of energy copper does this ore vein contain?"
