HIt The Priates

Now thanks to the new techniques development, fighting with the robbers on the sea, we don't use knives and guns. We have new weapons. We use MP3.
This weapon use loud sound that human ears can not receive to attack the pirates ship that may be away from 1000 km place. It's very powerful. This kind of weapon doesn't waste bullets, but it also cost a lot of money sixty-nine hundred thousand NT dollars, for this kind of weapon.
