"This Guo Zhen likely advanced to Fifth Grade first, and only recently completed the fourth Qi Blood Transformation... Truly deserving of being the White Whale Gang's genius, his Blood River is currently longer than mine."
Currently, Su Mu has just completed his Secondary Blood Exchange not long ago, with a Qi Blood River only three yards and two feet long, a yard and a foot shorter than Guo Zhen's on the stage.
"But Guo Zhen's Qi Blood isn't necessarily stronger than mine... His Qi Blood's purity isn't as good as mine!"
Su Mu's eyes narrow slightly; during this period, he has fought several Fifth-Grade Martial Artists and noticed that there are differences in the Blood River, not just in length but also in purity.
For instance, among those in the Jiao Blood Gang, Blood Wolf Woman and Liu E, Liu E's Blood River is a foot longer, but slightly lacking in purity.
Guo Zhen's Qi Blood purity exceeds even Blood Wolf Woman and Liu E, but still falls short against his own.
