Slight clouds flashed across the supposedly calm blue sky. Like the calm that Petra has been keeping. The calm that he woke up from the results of concentration training with Kin the past few days.
Therefore Petra pulled back the hem of the long skirt that she was wearing in her hands, afraid that she would lose control like the last time she did basic training with Kin.
"Remember Petra, the basic key and the most important factor in this practice is patience in trying to control the fire element. Because in essence, fire has a close connotation of the emotional fire of humans. And the embers are created from the overflowing emotions of the master. One point of failure in If you control yourself then the result is no joke. It's not only your memory that is lost, your life may also be lost. Burned by your fire." Kin said meaningfully, it was one cloudy day at their practice.
