Gu Jingang harbored suspicions.
There was a strong possibility that Gu Sheng was not merely in the Blood Refining Realm Great Success, but had reached the Perfect level of the Blood Refining Realm!
Thinking this.
He felt deeply shaken within.
"I truly cannot fathom how Asheng cultivates— within just a few short years, not only has his cultivation reached such incredible heights, but his mastery in martial arts has also become so profoundly unfathomable..."
In recent days, it wasn't only the Iron Stone Fist.
In many other aspects of martial arts knowledge, Gu Sheng displayed a casual fluency that completely won Gu Jingang over. He even once considered calling Gu Sheng "Master Gu," but Gu Sheng deemed it inappropriate and declined.
Watching Gu Jingang's departing figure, Gu Sheng slowly shook his head, roughly able to guess what was running through Gu Jingang's mind.
Actually, Gu Jingang's guess was both correct and incorrect.
