Zhang Ling's intelligence was slightly outdated, as he hadn't heard of Lin Yu's notorious reputation. Thinking she was a nobody, he urged his Snowstep White-foreheaded Tiger to advance upon her challenge.
Although it was a duel, having a Spirit Beast mount was perfectly reasonable.
The giant tiger surged forward with a roar, charging at Lin Yu. With the advantages of a long weapon against a short one, cavalry against infantry, and man against woman, Zhang Ling had the upper hand in every aspect.
Moreover, as the Second Warrior battling an unknown foe, wasn't his victory assured?
Zhang Ling sought not only to win but to do so swiftly and decisively, without dragging it out. That's why he had chosen what seemed to be the weakest opponent.
However…
Lin Yu was likely the person here with the greatest combat strength and the most intense intent to kill.
