The reason Hilbert showed interest in revealing himself to outsiders was not just because he didn't want to disturb Rommel's plans… If he had any issues, the proud disciple of Kamente Tower he had sought out and spent a long time with alone would also have problems.
Moreover, because the battle on the screen had come to an end.
Delphus got what he wished for… Just when he dared not easily take out the 'Order Jewel' for a risky attack, that Black-Clothed Mage used nearly all his strength to unleash two Eighth Ring Necromancy Spells on him: Black Flame Technique.
Hilbert could see clearly that Gilbert used this spell outwardly to spread over everyone around, forcing them to resist desperately… The spreading ability of the Black Flame Technique cannot be exempted by ordinary defensive spells.
Of course, it's not to the extent that it can't be extinguished, but it will inevitably consume a large amount of Mana.
