The burly man named Feng Tie was an Earth-level Army Commander at his peak.
He was acquainted with the Grandmaster Hengshan, a notorious flower thief; the two had once explored a secret realm together.
Within that realm, fraught with difficulties, several Earth-level Army Commanders perished.
Only he and Grandmaster Hengshan managed to escape.
Thus, he learned Grandmaster Hengshan's greatest secret.
Grandmaster Hengshan had received an inheritance from a visitor from beyond the skies and, emulating Thornblood, modified Strange Spirits, eventually merging with them to gain a bizarre power.
Illusion Technique!
The main reason Grandmaster Hengshan became a widespread scourge, renowned and yet never caught, was precisely because he mastered an Illusion Technique.
He always walked away with impunity.
This secret was probably known only to Feng Tie.
