Gao Yuan had already destroyed three artillery positions, each ammunition explosion obliterating at least dozens of meters around it.
As for the lethal radius, that covered at least a hundred meters—if the shells were launched into the air before detonating, then it would be truly impossible to estimate how extensive the damage could be.
Actually, it's not that easy to set off shells; if they aren't fitted with fuses, even an explosion of the propellants might not trigger sympathetic detonations in the shells. But the problem is this place is the front line, the forward position of artillery. As soon as there's a call for fire support from the front, or when it's time for daily artillery fire, they have to fire immediately.
Therefore, most of the shells piled outside were equipped with fuses, meaning that as soon as the propellant exploded, those shells would detonate one after another.
