Leonard Churchill was very clear that facing such an opponent, a direct confrontation wouldn't cause much damage.
He was more focused on observing and learning.
Seeing the old man unleash four spells consecutively, Leonard Churchill was amazed by his power, but what was more important was, "How does this guy master so many laws?"
The four cards used just now also meant that the old man had at least mastered the laws of ice, fire, earth, death, wood, and at least five other elements.
Normal card masters usually focus on mastering one or two laws. Because with more, it's jack of all trades and master of none, and the Elemental Affinity can't possibly be that high to train them to the Sixth Tier.
"Strange..."
Leonard Churchill's mind raced, "Being able to cast four Sixth Tier Mystery Level spells in such a short time must be due to the high technique bonus of a Forbidden Magic Device. Could it be the sealing of 'spells' that enables multi-elemental spells?"
