Lord Mighty's leap was nothing short of an incredible physical feat. He didn't only cross tens of meters with a single jump. He had also perfectly controlled his strength, arriving exactly where he planned to land.
That alone showed how Lord Mighty was no mere brute. His explosive energy and physical prowess were scary, but his ability to implement them in such a perfect display of battle experience was scarier. However, Khan didn't experience anything remotely close to fear.
In the past, Khan wouldn't have been able to move freely while his body was tense. That was one limit of the Lightning-Demon Style. Yet, the Transcendent Step was a different beast, allowing him to use the mana inside his legs to perform sharp, explosive sprints.
Khan could attack Lord Mighty before his massive arm could move by another centimeter. That was the depth of his aerial combat mastery, but someone had challenged him in that field anyway, without even wielding flying techniques.
