What Duke taught Robert was only the basic part of the Light Divine Breathing Technique, which could only support his cultivation to the Great Knight Realm. The high-tier part of the content has not yet been given to him.
If Robert's talent is indeed good in the future, and he can quickly master the Light Divine Breathing Technique, then the high-tier parts are not impossible to impart to him.
However, high-tier Breathing Technique involves the Life Seed Elementalization, content that is very core to any faction.
Duke would not easily let it out unless Robert could make sufficient contributions.
He doesn't need players to have high loyalty, as long as they can do enough things for him.
"The Divine Breathing Technique is divided into two parts. What I'm giving you now is just the basic part. If your performance is excellent later on, I might consider granting you the true extraordinary path." Duke said.
