"This is the nurtured Ghost?"
After being subdued by Lu Chenzhou, the Ghost had become obedient, but this was all an illusion. Should the day come when Lu Chenzhou's strength became weaker than it, this creature would surely turn against its master. The power of Ghosts was not static; the pool of water that gathered the Blood of Demons could also promote its evolution. Becoming a Shadow Level entity wasn't out of the question.
Of course, as a subordinate to the Divine Spear, whether it could transform depended on the will of the spear's owner. As long as Lu Chenzhou didn't allow it, the Ghost would never Breakthrough Realm.
Considering the chasm between major Realms and that Lu Chenzhou had not yet broken his own Second Shackles, he would certainly not allow the Ghost to advance; to do so would be akin to digging one's own grave.
In a thought, he left the space of the Divine Spear.
Lu Chenzhou gripped the spear in his hand and thrust it into the void!
"For the Tiger Form!"
