Finally, he took out three metal tubes from his pack.
Each tube was about the thickness of a finger and twenty centimeters long, its surface covered in dense runes.
These were the "Erosion Source Agents" Qiao Zonghan had given him before he left, specifically designed to contaminate energy veins.
The principle was simple: inject high concentrations of chaotic energy into the source of the vein, contaminating the energy purity of the entire lode. Contaminated Black Stone couldn't be used to forge equipment; any attempt to force its use would lead to an energy rampage.
The Federation's energy purification technology was at least a generation ahead of the Celestial Wolf Civilization's. Once the Federation secured this lode, they could purify it and have it operational again in three months at most.
'Three should be enough.' Xu Wuyi tucked the metal tubes into a hidden pocket inside his combat suit.
All preparations were complete.
