At this point, Shu Feng's physical constitution had far surpassed that of the King of Goblins, yet he still hadn't advanced to become a Spirit Master. This was because he had not yet vaporized his Spiritual Power.
Only by vaporizing his Spiritual Power could Shu Feng officially step into the Spirit Master Realm. The quality of vaporized Spiritual Power was far higher than the level of Spiritual Power Shu Feng currently possessed.
Using the same amount of Spiritual Power, the Membrane of Spiritual Power generated by a Spirit Master's Spirit Shield Technique was more than ten times stronger than that of a Spirit Warrior. This was precisely why it was extremely difficult for a Spirit Warrior to defeat a Spirit Master.
Ordinary Spiritualists would generally hit their limit after their Spiritual Power Value reached 9,000 or 10,000, and it would become exceedingly difficult to increase it any further.
