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
At first, Sha Jiu thought that Yi Bing was harming Hai Ba so he loathed Yi Bing. But, after that, he noticed that Yi Bing really has some problems. So, it wasn't intentional what happened between him and Hai Ba before. However, Sha Jiu really couldn't let go because Hai Ba has suffered, and can't become a combatant grim reaper anymore. While, on the other hand, Yi Bing just shone brighter.
"What's wrong with Yi Bing?" Sha Jiu asked as he pulled himself from his thoughts. "After I contemplated what happened before, I can swear that Yi Bing has really lost his power at that time. But, why did he recover it after? How did he recover it?!" he asked.
"I don't know!" Gu Shi answered.
Sha Jiu frowned. "I am more curious of how Yi Bing regained his power than hate him for what he did." He said.
"… so that's why you are very particular as to what's happening around Yi Bing?" Gu Shi helplessly said. As expected of a researcher!
