Gluttonous Devouring Technique!
That technique was a Sage Ruler Technique in which Chu Kuangren had obtained from the Black Light Sage. It was an incredibly strong technique that enabled the user to establish a refining dimension within their bodies. Cultivators who were sucked into that dimension would have their blood and flesh essence subsequently processed.
If the target were ordinary cultivators, Chu Kuangren could use the Gluttonous Devouring Technique on them without fail. However, facing an Honorable, Chu Kuangren would need to first weaken his opponent till the brink of death before using that technique. Otherwise, based on his current level of cultivation, Chu Kuangren would not succeed in using that technique.
The dimension that was created by the Gluttonous Devouring Technique was one of pitch-black darkness. After the Thunder Falcon Tribe's Honorable cultivator was sucked into it, an immense fear started to well up deep inside him.
