Because of Pan Feng's death, the Divine Soul Imprint within this hammer-shaped Spiritual Artifact had already dissipated due to the dispersal of its master's Divine Soul, making it easy for Ye Zhen's Divine Soul Seal to imprint upon this hammer-shaped Spiritual Artifact.
However, this did not mean that Ye Zhen could now activate this hammer-shaped Spiritual Artifact. After the imprinting of the Divine Soul Seal, Ye Zhen could only initially activate this hammer-shaped Spiritual Artifact, controlling the leakage of its Spiritual Energy and barely manage its transformation in size.
To use it to attack others, it would be impossible without several days of Divine Soul Nourishing, and to wield it as if it were an extension of his arm would require a much longer period of Divine Soul Nourishing.
Nevertheless, this development thrilled Ye Zhen to no end; he had not expected to obtain a Spiritual Artifact so easily, even though it was only a Low Grade Spirit Artifact.
