[Siren Breathing Technique: Level 5 (Maximum)], Special Effect: Intermediate Speed, Bone Shrinking Transformation.]
..
"So, the fifth level is the limit of the Siren Breathing Technique?"
Levi felt the black gas from the Siren Seed entering his limbs.
He quickly punched out. His fists were like phantoms, and each punch carried wind.
Then, with a whip kick, the air seemed to crackle.
"My attack speed has increased quite a bit. Let's go test my running speed."
Levi came to the venue where he had tested himself before.
His entire body tensed up, and his back arched slightly like a cheetah with its eyes on an antelope. Then, with a bang, the black gas from the Siren Seed and the Frost Wolf Seed burst out from his legs and core area!
Levi turned into a blur.
His current speed was much faster.
One, two, three, four seconds.
In just four seconds, Levi had reached the finish line.
