When he was done picking what he needed, he had become more difficult to kill because of his leather armor, faster because of his shoes, and stronger because of his new weapon. He felt like a completely different man.
He waved the weapon about in appreciation. "Let me go and do some more training to get the hang of this sword. Then I will grind missions."
This became what he did with most of his time. He trained, went to the real world to sleep, came back to grind missions until he couldn't anymore, and then used his new training points to buy a new weapon.
He did spend some time to trade his old weapons for some training points with others who couldn't afford to buy a new one. The durability of his old weapons has fallen, but they are still powerful, and most importantly, they are still cheap.
