In the following days, Jack just did his routine. Completing Greed's compulsory portal while grinding inside the endless wave portal.
After repeatedly going through the endless wave portal, he was getting more used to the mutated soldiers inside that portal. Hence, his speed of clearing the waves picked up. On his best day, he could even complete five rounds.
Since he counted twenty-two trees that had portals, he wondered what would happen after he completed all of them. Maybe Greed would let him go? Then one day, he saw a twenty-third portal on a tree that didn't have one before.
'Motherf*cker…! Did he add a new one? This is not going to end then,' Jack thought with apprehension.
During his foray into the portals, he met one that he was interested in as much as the endless wave portal. The portal was the one he entered today. The portal took him high up in the sky and placed him on the back of the neck of a large red dragon.
