With two fire spears, David was able to clear a large number of zombies at the front of the march that were currently making their way towards him and his father.
Thanks to his attack, the semblance of order that was in the marching zombies—not because they were sentient enough to do so, but because they just happened to perfectly fall in line—got destroyed.
A few zombies were obliterated to pieces. Some had their limbs blown off. Some fell hard on the ground, which caused the other zombies behind them to trip over them, creating a chain effect.
After doing this, David jumped back and fell behind his father as Malachi took the lead.
To this move, Malachi was not surprised. If anything, he seemed satisfied.
David was also physically strong, but his main strength was not that. It was his explosive power, which made him a great damage dealer and at the same time, a great support.
