As he heard the sounds coming from his right side, his senses immediately heightened and he became alert.
He slowly moved his neck and looked from the small holes in his vine cot.
There, he saw some black shadows sneaking towards them.
'Who are they?' He frowned and started circulating his mana.
Fire elemental mana started to swirl around his right fist without making any sound.
Due to him solely focusing on the [Calidus Brachium], his control over it became more refined which reduced the cast time by ten seconds.
Furthermore, he found one more way to save the time when casting this spell. That was to gather and compress the mana required to activate the spell in advance, around his fist.
However, this task wasn't as easy as it sounds like because, he had to hold the compressed mana and not let it disperse until it was time to cast the spell.
To do this, one had to have high affinity with their mana and great control.
