Wooyun spent the next few days training alongside his master to get the first layer down. Right now, he was in the process of developing the foundational technique known as the Petal Vein Flow. This technique allowed the user to circulate both positive and negative qi through two mirrored pathways. Negative qi flows through "shadow veins," designed to prevent spiritual damage.
"This is used as a base for all the following techniques you'll be introducing into your body as you pass each layer. Without this, you won't be able to move forward."
So everything rests on me mastering this petal vein thing, huh? Wooyun taught at the time, but once he'd come to terms with his feelings, it was easier for him to let the two energies in. Once Junghwa gave his approval, he was finally able to move to the second technique: the ink step bloom.
