Blergh!
As soon as Lee attempted to move the wind particles, he involuntary convulsed and spewed out a mouthful of blood. And then another one.
This wasn't what he went through after regaining consciousness when Arax fed him the earth spark. Back then he only coughed up the blobs of impurities that had accumulated while he was unconscious.
Now he was actually internally bleeding. And externally as well. Blood was seeping through most of the tiny cuts across and for a split moment Lee felt as if he was a sieve.
Fortunately, he didn't bleed out. Lee forced himself to calm down and performed a simple breathing exercise, designed to normalize the flow of elemental energies, and that stopped the bleeding pretty quickly.
One didn't have to be a genius to realize that the damage was caused by the wind element that tore him apart from the inside. Either there was a trick to using it, or a technique, but it was clear that before attempting anything Lee had to recover first.
