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
Yi Bing's face is as dark as the bottom of the pot again while, in contrast, Huo Ling's face is as bright as the sun today. His heart nearly stopped (though it had already stopped) when he saw Huo Ling fell from the building. His whole body became cold (though it has always been cold) after he received a fright from Huo Ling. He didn't expect for the other to be mischievous to this extent. His mind had become blank.
It was only later when he saw Huo Ling appeared that his brain started after it malfunctioned from fright. He wanted to harshly scold the other, however, when he saw the other's satisfied and peaceful expression, all the words he is about to say has disappeared.
