When a steam locomotive suddenly came to a stop while traveling at high speed, if the inertia couldn't be precisely predicted beforehand to adjust for one's center of gravity, then there would definitely be a huge loss of balance.
Balance was one of the most important things for every combatant.
Not to mention a battle between supernatural beings, even if it were just a battle between normal people, a combatant who had lost their balance was as good as a fish on the chopping board.
The Pyro Company members had extremely good physical fitness, and normal supernatural beings could not compare to them. Therefore, at the moment of imbalance, they quickly used their feet to adjust their center of gravity so they would not end up in a particularly sorry state and bump into the shadow clone's blade.
But as long as they were thrown off even a little, they would definitely expose an opening.
