Sam hadn't used the full power of his Thunder Blade attack, so he had enough spiritual energy left, though the tornado itself was formidable—and direct contact would have seriously injured him.
At least now, Sam had a clear sense of Lisa's full power. Though she'd grown much stronger than he remembered, he was more confident in his chances to win.
'I'll have to go all out, or I'll lose.'
Lisa realized the same thing. Next, she began assaulting Sam continuously with her techniques.
It took time for her to form another tornado, so she needed to keep Sam at bay until then.
Before she could activate her next technique, what if Sam pushed her back? That was why she wanted to keep him at a distance, bombarding him with wind blades.
These blades were invisible to ordinary eyes, but Sam's shadow vision allowed him to see every one.
His quick reflexes let him dodge most of the attacks.
