With a thought, a "Rasengan" appeared in Qian's palm.
Immediately afterward, a large amount of wind-style chakra poured into it.
Very quickly, the Rasengan's shape changed. Four chakra-formed Wind Blades appeared around it and began spinning at high speed.
At the same time, an ear-piercing sound of friction spread from his palm, as if the surrounding air had been torn apart.
No, it was not as if—the surrounding air really had been torn apart.
The rapidly spinning Wind Blades directly ripped open the air around them, bringing up a whistling gale.
Qian stood there, his hair blown into wild disarray, while the skin on his cheeks faintly stung.

"'Fire Release: Great Fireball Technique.' This name doesn't seem very suitable anymore..."
In that case, it was only normal for its Proficiency growth speed to increase.
This was no ordinary ninjutsu. It was the S-Rank Forbidden Technique—Wind Style: Rasenshuriken!
