Chapter 624: Burning your Life Force has a Fatal Weakness. 

"W-What have you done…?"

Nawdren completely ignored whatever Nux was saying and questioned with a pale face.

A deadpan expression appeared on Nux's face.

He then shook his head and sighed,

"So as I was saying,

Burning your Life Force has a Fatal Weakness.

It exposes your Life Force which is usually located deep inside your body under many different 'barriers'."

Nux revealed and suddenly, Nawdren's expression changed.

Exposing his Life Force…

Then for Nux, who could Devour Life Force…

"Yep, what you are thinking is correct,

Burning Life Force in front of me, who has the ability to Devour it…

It is nothing but offering your life to me."

"!!!"

Nawdren's eyes widened in horror.

"And you know what's worse?" Nux brought his face close to Nawdren and questioned.

Nawdren glanced at Nux and gulped, fearing the words he would speak next.

"You don't just expose your Life Force, you also expose the 'connection' you use to exchange your Life Force and Mana.
