'Baby steps.' Lith thought, using his own fingers as a scaffolding for the spirit magic barrier. Soon his left hand was covered by a thin and eerie green glow.
'This stuff wouldn't block a pen stroke and is thinner than a hair, but it's still a barrier.' He thought. 'Now let's try to move it away from my fingers.'
A sudden knocking on his door made him yelp and shattered the infant spirit spell.
'Nice job.' Solus laughed. 'If we ever have to use it in battle, we must hope that our enemy is as silent as a mouse.'
"Lith? Do you mind if I come in? Phloria asked.
"Not at all." Lith tried to open the door with a spirit spell and failed miserably. Even from barely a few meters of distance, the green glow was so faint that Solus's mana sense could barely perceive it.
