Arthur had prepared himself for the worst.
He knew he would have trouble with the second step of Flame Core Concealment, Constriction.
After all, the day before, he'd had trouble with a similar second step of the king's own tailored version of this process.
On the bright side, Arthur had the Age of Phoenixes. The mysterious book had provided him with far more information than his father had offered him. Tricks and techniques he could try.
At least, that was one thing Arthur had looked up to.
And even then, he'd never once thought the 'Age of Phoenixes' to be some miracle worker.
No… Arthur knew what his unsealed core for the boiling ball of mayhem looked like… even though always appeared more chaotic each time he saw it.
The inferno ball of flames kept gnawing at his confidence to contain the behemoth of a core.
Arthur maintained steady breathing for a few more seconds and managed to calm himself down.
