If the Blood Moon Clan merely needed a small amount of Serum Grass, Lin Li could give them the Serum Grass from the swamp. Although the Serum Grass was rare, it seemed to be a useless herb to him. If it were a barren and useless swamp, Lin Li wouldn't mind giving it away in exchange for one less enemy for the Tower of Dusk.
However, the swamp area contained an abundance of rare magical metals which, although not the main materials for forging weapons and equipment, were absolutely indispensable. In the process of forging weapons and equipment, a qualitative improvement in the performance of the magical weapon could be achieved with just a minute amount of those rare magical metals. In addition to forging, the rare magical metals were also widely used in producing mageweaths, magical accessories, and Alchemy Arrays. How could Lin Li easily give up such important ores?
