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
Aside from that 'exhibition match', no other unexpected events happened. Yi Bing, Huo Ling, Shou Ji and Shi Jiu successfully passed. Yi Bing's opponent forfeited while Huo Ling's opponent underestimated him, thinking he is easy to bully because of his appearance. Reality proven him to be cruel and he suffered mentally like Shou Ji's opponent did.
Shi Jiu's opponent is a fair opponent. They are equal in mental strength and physique but Shi Jiu is stronger than him spiritually. But, Shi Jiu proposed a physical fight and also weapons and Shi Jiu won. His opponent also has no hard feelings and accepted his defeat, congratulating him.
