Lu Li once developed a sword art on his own which was not a kind of Xuan Skill. Nonetheless, his was powerful as well. The only feature of his moves was fast, each move faster than the previous one.
For two months, Lu Li had been thinking that the Profound Meaning contained in the tornado must have something to do with wind or strength. After all, the force contained in the wind was formidable.
For two months, he had tried to feel the wind and the force in the tornado. He tumbled to the truth at this moment. He had been working in the wrong direction. What he should take away from the tornado was not the wind or the force, but the speed.
Fast!
Speed was actually a kind of force and could generate lethal effects.
For example, there was a rock. If it was an average rock, some warrior could just break it. But what if the rock was traveling at the fastest speed?
