In his past life, Yusuf Zuck cultivated by leaps and bounds, killing beyond his level, and since embarking on the path of cultivation, he never truly trained seriously!
How to put it?
Everything he did relied on external aids, propelled by Purple Blood Beads or miraculous treasures.
He never sought solitude in a cave to comprehend the realms, grasp the Heavenly Dao, and feel nature, like other cultivators!
He didn't have to do anything; consuming miracles and supplements alone would make him stronger!
Such a situation was abnormal; any cultivator seeks to connect with the heart of nature, pursuing the truth of the Dao through understanding.
Yet he only chased after increased power, like a penned pig that grows fat with constant feeding, without experiencing the natural life.
Thus, he was a failure.
And today, when he again imitated his past by fattening himself with supplements and Elixirs, it suddenly ceased to work.
