If the outside world knew that Ye Feng was already using top-grade Celestial Marrow Stones for cultivation when in the Martial God Realm, they'd definitely scold him for wasting heavenly resources.
Indeed, in the hands of ordinary people, treasures like top-grade Celestial Marrow Stones are generally only used by powerhouses above the Martial Immortal; who among those below the Martial Immortal could afford such treasures?
Moreover, those who can use top-grade Celestial Marrow Stones are generally powerhouses among the Martial Immortals, and ordinary Martial Immortal powerhouses aren't qualified to use them.
Yet, when it comes to Ye Feng, not only do top-grade Celestial Marrow Stones get used by this Martial God, even the Celestial Spirit Stones are used by him.
Because the cultivation technique Ye Feng utilizes is not on the same level as common cultivators'.
