50,000 years ago, Hell was destroyed because of too much Foul from the resentment of the souls that later turned to Soul Eaters and devoured everything in their wake, leaving nothing of Hell. The gods above in Heaven, in order to take care of the newly-died souls, created the Afterlife Department comprised of grim reapers. Huo Ling was delivering food that day when he met Yi Bing and the guy gave him a warning. When he arrived to the customer's unit, he was killed. Huo Ling: you set up a death flag for me! Yi Bing: I'm a grim reaper. I'm the flag myself. Let me help you solve the mystery of your death. Huo Ling: your sister! Alternative title: The Different Ways I Died at 23 Update: daily
"Sure!" Jin Wu agreed with Yi Bing's decision. "A master and disciple pair." He said.
This is a sensible decision. Although Yi Bing and Jin Wu are colleagues for a long time now, but their personalities clash against each other, and they have never once collaborated with each other. Instead, they have been working with their respective disciples recently, and so they could work better with their disciples than with each other.
Also, Huo Ling and Mo Shi are their disciples, and are weaker than them, so naturally, they have to take each of them with them to protect them. Thinking this, Jin Wu grinned at Mo Shi.
Mo Shi felt all the hairs on his body rose at their ends when he saw Jin Wu staring at him and is grinning. "Uhm… can I pair with Huo-ge, instead?" he asked and glanced at Yi Bing with a pleading look. He still hasn't forgotten about Jin Wu's harassment to him before! Although Jin Wu said that he is just joking, but he can't let it go!
