Lin Xinghai was shocked because what shot out were not tennis balls, but iron balls.
The iron balls were faster, leaving at most 0.5 seconds of reaction time between leaving the port and hitting the ground.
0.5 seconds was cutting it extremely close, and the most terrifying part wasn't even the speed.
What was terrifying was that some kind of magnetic device must have been installed on the walls on either side of the shooting range, and it was currently releasing an irregular magnetic field.
This caused the falling iron balls to be pulled by the magnetic field, making them constantly change trajectory as they descended.
Faced with such a variable, even Lin Xinghai was flustered, only barely managing to hit the first iron ball.
And unlike before, he failed to hit the center of the iron ball; the bullet only struck its edge.
In other words, he had almost missed.
