Wizard Jason did not die. Instead, he strode out of the hall step by step, glaring deadly at Merlin with a dark expression.
Merlin was also observing Wizard Jason. He noticed that a translucent light shield had surrounded Wizard Jason's body. It kept absorbing Light Element from the outside.
"Spell Scroll? On top of that, it far exceeds First-level spell!" Merlin murmured in a low voice. He could sense that translucent light shield on Wizard Jason was also a spell. Moreover, it was a high-level spell. It was not something Wizard Jason could cast.
The only explanation for this was that Wizard Jason had a Spell Scroll on him. When Merlin had surprised him by casting Frost and Large Fireball, Wizard Jason felt that he was threatened, thus he took out the scroll and initiated the spell in the scroll.
