Thanks to all that beatings and guides, before he could fully heal himself, Tobi quickly started to feel the bottlenecks, and soon he felt the black impurities were trying to find their ways around his Mana core like little maggots.
As Tobi realized what was happening, he quickly undressed himself so as not to stain his clothes, even though it was nothing more but rag.
This time with Horus overseeing him, he suffered no resistance. Discovering that it wasn't so painful after all, Tobi expelled far more impurities than the previous times, letting them all out from his pores and orifices.
The stench was so bad that he would have fainted, if not for Horus constantly providing natural Mana beside him. After removing so many impurities from his body, he was completely exhausted together with that of the training he felt like sleeping in a warm bath.
"After a bath, I swear I could eat a whole mansion filled with meat."
Horus ignore Tobi's remarks, as he stared at him.
