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
"It is senior Yi and his apprentice!" a junior grim reaper exclaimed when they saw Yi Bing and Huo Ling passed by.
Yi Bing and Huo Ling heard the voice and saw two junior grim reapers who were on the park. They went to them and turned back to their human form.
"It is you two." Yi Bing muttered as he looked at the two junior grim reapers in surprise.
"Senior recognized us!" the one who spoke just now exclaimed in both surprise and joy.
"You know them?" Huo Ling asked and looked at Yi Bing, before he turned back to look at the two junior grim reapers again. He felt that these two are familiar… but he doesn't know why and how they are familiar.
Yi Bing started and looked at Huo Ling. Then, he remembered that Huo Ling met these two once during one of Huo Ling's reincarnations when the two junior grim reapers went there for a mission – fetching souls.
