章 240: Chapter 240: True Lord Golden Spirit

Inside the Metal Immortal Chart, no vegetation grew, only various Metal Attribute Heavenly Materials and Earthly Treasures were being nurtured, including the top-tier Metal Attribute Heavenly Material and Earthly Treasure, Geng Metal.

Just adding a trace of Geng Metal to a Flying Sword Magical Treasure can enhance its sharpness significantly. Naturally, this treasure was highly sought after by top Sword Cultivators and had either been mined out or fallen into the hands of top cultivators.

Zhao Yu had not found anyone selling or trading Geng Metal in both the Great Qian Empire and the Blue Sky Sea, two Cultivation Holy Lands.

One of the capabilities of that Metal Immortal Chart was that as long as Metal Attribute Heavenly Materials and Earthly Treasures were continuously inserted, it would nurture rare Metal Attribute Heavenly Materials and Earthly Treasures like Geng Metal and Taibai Fine Gold inside the Immortal Chart.
