Upon realizing that this Purple Thunder was not a real tribulation, but rather seemed to be refining his own body, Yusuf Zuck completely gave up resisting when the third bolt of lightning struck down.
Of course, although he had given up on resisting, the Blood Beads in his mind did not. They continued to release a purple glow that cleansed his entire body, while also absorbing the energy of the purple lightning.
With no serious harm befalling his body, Yusuf Zuck confirmed that the Purple Thunder could not kill him, and he completely let go of any worries.
And as the lightning bolts kept striking down, Yusuf Zuck could distinctly feel his body getting sturdier, and his strength climbing substantially.
The thunder struck down a total of eighty-one bolts, and after the eighty-first lightning bolt, Yusuf's body was laced with blue electric arcs that flashed and shimmered as they coursed through him.
