“Your mother is right, Faluel.” Solus replied. “The metal plating and the crystal case are both hollow and serve the same purpose. To accumulate and store large amounts of world energy indefinitely, allowing the tower to operate at full power when there is no mana geyser available.”

“It’s one of the last floors to be recovered because it was the first to be destroyed.” Menadion sighed. “After my demise, the tower consumed every drop of energy in the Fusion Reactor and then the Reactor itself before cannibalizing the rest of its enchantments to keep Solus alive.

“This entire floor serves no purpose once it’s depleted, so the tower core cut it off as the first withered branch in the hope of prolonging its existence while Solus looked for one of our friends to take my place.”

“Why call it Fusion Reactor, though?” Lith rushed to change the topic before the kids started asking questions about Menadion’s death. “This place stores energy. It doesn’t produce it.”

“Because the world energy accumulated here becomes immune to all kinds of elemental sealing arrays, and the tower can circulate the power of the elements just like true mages do with Fusion Magic.” Ripha replied.

“With this beauty by your side, you can instantly Tower Warp the moment you find a mana geyser, enjoy the protection of the tower’s arrays and defensive systems, shoot all kinds of spells even while under the effects of Frost Soul, or use the Watchtower to scout your surroundings.”

“What about the Prime Engine or the Cannon Vault?” Lith asked.
