Dharma's Edge: Fourth Stance

In that very second, two heads burst through the boat, roaring at them. Ling Xiao gasped when she saw this.

Her eyes lingered on Li Chen's side profile before she faced the beast. A sharp glint flashed through her eyes as she spun her swords, generating a gale that made Li Chen's hair flutter. 

"Crimson Destroying Twin Slash"!

Two massive crimson arcs swooshed out. The scaly necks of the beasts.

'She uses more of her body's essence than star energy,' Li Chen said inwardly. 

He stood by Ling Xiao's side, examining her like a weak scholar. Her body exerted its strength to execute her strikes. Body cultivators naturally have essences like beasts because they choose to nourish their bodies, transforming them into behemoths.

The body naturally produces and stores essence, a powerful energy that can serve as a substitute for star energy, but star energy functions similarly to fuel for elements.
