Of course CSZ will be fine and won't have white energy corruption - GCC didn't have black energy corruption! Whatever curing him cost him, it had to be in some ways equivalent to what GCC was suffering from.

It works so well!!! And it fits in with what we learn later in the drama, that GCC's white energy is so pure it can even be blended with black energy. Or, as Ye Zun says, "His spiritual energy is pure and bright."

"Rather, they're perfectly compatible."

So GCC couldn't have had black energy corruption!
