As he searched, the cruise missile approached Buckingham Palace.
If something didn’t change, it would scatter the 200 smaller explosives and an area of the city with a radius of 3 kilometers around the palace would truly be blown away.
And then…
“To zero!!”
A new voice reached Villian’s ears from a distance.
Immediately afterwards, the cruise missile malfunctioned instead of scattering the smaller explosives in every direction. Even when it reached the designated point, the missile’s outer shell did not open, the flame propelling it from the back disappeared, and it fell to a road outside the palace grounds like a wild pitch. The cruise missile had to have weighed quite a bit, but it rolled while bouncing multiple times instead of piercing into the road.
