Using the same trick that I did for the clockwork heads of these bozos, I cast Tidal Break at the thickness of two meters in front of each of the incoming bullets that were probably confused on why their targets were on the ground. Obviously, it wasn't like it wasn't going to change its trajectory and not hit me.
As they collided with the concentrated barriers, they unleashed a shrieking of magnetic pulses before expanding to the size of a disco ball, then imploding themselves like a dead star.
There weren't any chemical substances from the imploding graviton, but it seemed like I was at the right call to manifest the barrier before the bullets could reach the clockwork people and me.
