Before advancing to the Third-Level Great Sorcerer, Green had already been arranged to reside within the Seven-Ring Holy Tower, assigned a Demon-Hunter Laboratory far larger than during his time as a First-Level and Second-Level Wizard.
It seems this Ancestral Blood has indeed long been positioned by the Seven-Ring Holy Tower as a precious artifact, certain to aid Second-Level Wizards in advancing to Third-Level Great Sorcerers!
The entire Demon-Hunter Laboratory is a hundred meters high, with a length and width of a thousand meters each. The gigantic building is constructed from synthetic metal and special materials from various worlds. The vast hall is spacious enough for the Thousand-Eyed Giant Crab and Enigmatic Thousand-Headed Bird to fly freely, meant for Great Witch Hunters to place large experimental equipment.
Besides this, there are dozens of small laboratories for the wizards to decide their purposes according to their needs.
