The system prompted me asking which of the swords was to be used in the skill. My Emperor Qin’s Sword was the main sword used in attack and defense, thus, I decided to use the Cold Iron Sword instead. Soon after the interface flashed before me, and prompted me to choose a trajectory path. The range of the attack was 50 yards. I could also choose between a straight or curved track. The trajectory and angle were fully customizable. Tsk, this skill sure does take up a lot of energy.
