But before he threw it, Di Tou couldn't help but pause for a moment and observe the needle. Being made of Spiritual Sense, the needle didn't have a physical appearance, and Di Tou could only 'see' the needle because it had been formed from his own Spiritual Sense. Beyond that, because of the somewhat lacking nature of the technique he had practiced, there seemed to be a slight shimmer in the air if one stared precisely at where the needle was floating in the air.
Of course, although this was a flaw, it could be considered a rather minor one. After all, in the midst of a fight, who had the attention to notice such tiny details like these? and even if they did notice, the amount of attention they'd have to split off to notice the hints of needles might not even pay off, as they were still in the middle of a fight!
