Was Long Yi aware of this matter?
Without any surprise, how could Long Yi not know? He basically killed all the humans himself. It never crossed his mind that the Emperor of the Sanctuary Empire would stoop to such despicable means as to send an assassin, especially since Long Yi, who detested such methods, showed no mercy and killed all the enemies. Originally, he intended to deliver the news to the Emperor of the Sanctuary Empire personally, partly to probe the enemy and partly to further fuel the fire. However, Little Zi insisted that such a trivial matter wasn't worth Long Yi's effort; a mere maid could resolve everything.
After much insistence from Little Zi, Long Yi could only agree. However, Long Yi had actually been following from a distance all along, and it was precisely because Long Yi used a contract to summon Little Zi that she mysteriously disappeared at the end. So, of course, there were no traces of magic, because it wasn't magic at all!
