This old man didn't use his full strength to the very end, which left Malin feeling somewhat regretful. He knew this was because Gaiate was afraid he couldn't hold back his power, but how could the old man know that his son also refrained from using all his strength to avoid beating his father to death with a single blow.
Without any blessings, and with his power somewhat restrained, Malin simply didn't want to kill his foster father with one strike.
Well, anyway, he had done his best, whether this old man would die out there, that was up to fate to decide.
With that thought, Malin felt he had done all he could, just like Maya, although she was reluctant, she eventually watched her father get on the train—the weekly service to the Central Administrative Province. There, Gaiate would take the train to the human heartland, and then he would travel eastward to the Eastern Kingdom, near the Great Death Zone.
