Two years ago, before Zhang Tie set for Western Theater of Operations, the seed bank that he ordered from Jiang Clan of Herbal Palace had arrived at Fire-Dragon Bounty Territory.
Although being a bit late, the seed bank contained enough seeds in quantity and quality, including 125,471 underground plants, 39,817 aquatic plants as well as hundreds of thousands of kinds of plant seeds. After the arrival of these seeds, Zhang Tie had teleported them into Castle of Black Iron and had Heller deal with them. As of now, except for over 100 rare plants, all the plants in the outside world could be found in Castle of Black Iron.
In recent years, these plants provided more and more Reiki for Castle of Black Iron. Plus the Reiki that was provided by those earlier plants, the quantity of Reiki that Castle of Black Iron could produce per day could already match that of basic energy storage that Elements Abyss could convert every day, even more than the latter.
