Extreme Yang Qi
"Wow… I didn't know you could do that… Preserving Yin Qi to cultivate later… Dual Cultivators are truly something else," Lian Li mumbled, feeling as though she'd just learned of a whole new world.
"It's not uncommon in our world. In fact, some dual cultivators even store their own Yang Qi or Yin Qi and sell them to other dual cultivators— of course, only the powerful ones with unique Yang Qi or Yin Qi would be able to sell it."
"W-Wait a second… Selling Yang Qi and Yin Qi?" Lian LI stared at him with a gawking look, and she couldn't help but wonder if he'd done such a thing in his previous life.
Su Yang smiled when he saw her face, and almost as though he could read her mind, he responded, "Yes, I have done it before— selling my Yang Qi to dual cultivation sects. In fact, my Yang Qi used to be so popular that sects fight just to have a chance to buy it."
