"Rex, it's time for you to come out." Kraft was in the deepest level of the Dungeon Maker with the System's supervision as he unlocked the very last fox which the System had kept.
Aside from Pei who was currently making sure of Jin's condition in his fight against Zeru, the rest of the foxes were present to witness the unlocking of Rex's cell box.
Its outer form was very similar to a giant and very advanced level complicated Rubik's cube. Numerous combinations were unlocked, including Legendary Grade sealing inscription charms to prevent him from coming out.
Pepper's task to discover the properties of the magical living armour plate was interrupted once more, as the System needed her to remove the previously added custom made barrier, the Reverse Aegis. It had been a perfect addition to Rex's holding cell since its property to absorb almost every type of energy in order to maintain its barrier form was a boon for the berserk fox.
This was my Panditor's most favourite chapter. (for obvious reasons.) He and I put in a lot of effort to make this chapter one of the more important world building chapters in the novel.
