Bloodline transformation signifies that the bloodline within a martial artist's body has been nurtured and grown strong enough to be used for Vein Forging.
At this moment, the four streams of Blood Light shooting forth from Ye Zhen's back indicate that his bloodline has undergone this transformation. What is unique, however, is that among them, two of the streams are as straight as wolf smoke, shooting straight into the sky, more than ten times larger than the other two, and they faintly emit both gold and black radiance.
This signifies that those two bloodlines have already undergone Vein Forging, but it doesn't mean that Ye Zhen's Cultivation has broken through to the Vein Forging Realm.
It was only after Ye Zhen's Cultivation reached the peak of the Fifth Stage of the Soul Sea Realm and he communicated with heaven and earth that he would be able to break through to the Vein Forging Realm.
Of course, this applied only to Ye Zhen.
