In the hidden storage room:
Maximus and Luna were resting after killing more than a hundred undead.
"It's exhausting," Maximus sighed as he rested.
Although he seemed to be only playing the piano and assisting in the battle, it was really tiring.
He was like a grand maestro guiding all their movements and tunes; without mana, he could only use his bare soul power.
"You're still amazing, husband," Luna said, her eyes shining.
"Hmm."
Maximus then looked at the undead crystal core.
"This can be used to replenish the soul or strengthen the body," Maximus concluded as he felt the energy within.
"It's a pity, we can't use it too much." He added
"Anyway, it'll be gone after we get out of the trial," Luna said.
Although the undead crystal core functions like a magic crystal, it's impure; taking too much without restraint will turn one into an undead.
