Atlas' lowest floor was a restricted area that almost no one could access. The reason for such high-level security was that it contained that magic tower's energy pool.
As its name suggested, the energy pool took the form of a large reservoir where the Pseudo Rank 7 Magic Tower stored massive amounts of natural energy and Origin Power.
Due to its level, Atlas' energy pool contained extremely potent, wild, and unrefined forces. The liquid that filled the reservoir took a grayish golden color, and the flesh of average Rank 5 life forms would melt if it entered into contact with it.
Even Rank 6 life forms would not dare to maintain extended contact with the grayish golden liquid in the energy pool.
Despite all that, there were two large bodies submerged inside the energy pool at this moment. They were both badly wounded, and the energy that most life forms considered poison due to their wild and unrefined state was like a panacea for them.
