Capítulo 399: Floor Hundred.

Han couldn't stop the chuckle that came out when he heard that Orochimaru swallowed Gretha. For some reason, he couldn't see anyone else but Gretha doing something so stupid. Han decided that he would get Orochimaru to release her when it gets back. Gretha might be an idiot, but Han needs her alive to help him on the upper floors. It won't be good to not have anyone to watch your back when you're in hostile territory. 

It sounds crazy to me whenever I think about it, but Gretha is actually the strongest out of all my allies. And she will be the most useful up there.

She knows the celestial plane like the back of her hand because she has lived there for years already. If there is anyone that can watch my back, then it is her. I just can't believe that crazy woman is the only person I can trust to watch my back up there. I really have my work cut out for me. Han sighed in tiredness.
