The construction of Noah's underground facility didn't take much, the workers were cultivators in the second and third rank after all, digging and soundproofing the structure was easy for beings of such power.
The structure had four separate areas, one for the slaves, one for the magical beasts, a reinforced one for the experiments, and one where Noah could rest or cultivate.
Noah entered the structure followed by the slaves that he had recently purchased and ordered everyone else to leave, there had to be no witnesses to his experiments.
"I've gathered the "Breath" that you asked for, Prince. The cultivators in the liquid stage of the third rank here are only of the fire, water, and wind element but there should be a larger variety once the link between your mansion and the archipelago is completed."
Kate spoke as she handed a space-ring to Noah, she bowed before leaving him alone in the just built facility.
