"Ka-chak."
A chilly aura leaked from the thick glass container and created a layer of frost on the surface of the container. Even Merlin's fingers were frozen by it.
"Guardian Monument!"
Merlin was taken by surprise. He suddenly recalled that the hundred years' ice bone marrow was a strange item; it could freeze anything once it was released.
Merlin's finger was just slightly frozen by the chilly aura but it had already gone numb and unable to move.
After Guardian Monument had shrouded Merlin's entire body, the chilly aura continued to spread and rapidly froze Guardian Monument as well. It was more powerful than Merlin's Large Frost as common spells such as Guardian Monument could not stop the freezing ability of the hundred year's ice bone marrow.
Once he realized that, Merlin quickly sealed the glass container, finally stopping the spread of the aura. For his finger, he cast Furious Flame to heat it for a long while to melt the ice crystals.
