The second spear was called Spear Sound. This was a simple art that allowed one to create powerful explosive sounds as their spear moved through the air.
These sounds were not just for show. They were meant to stun the enemy. Kai Syaoran did not know how effective this art was but he knew the power of sound over men.
As he practised this art, the sounds made by his spear became louder with each move. Each change in his spear was accompanied by an explosive sound that shook the ground even if slightly. The sound soon became powerful enough to make even someone like Kai Syaoran flinch. The sound did not have any effect on him but if one was less experienced in combat, they may be distracted by the sound leading to their defeat.
It took only seventeen hours for Kai Syaoran to completely master the art and even begin having thoughts of making improvements to it. He chose to keep this though for later. Right now, he had to show off for the stalker lady.
