Rule Horror: I Can Make Unlimited Trial and Error

[Horror + supernatural mysteries + livestreaming + no female lead + deduction + unlimited retries] The eerie domains of the myriad heavens descend, and endless livestreams begin. The chosen challengers struggle to survive in the domains' endless cycles. Treasures hidden in the instances, bodies strengthened beyond human limits… The victors can obtain everything they have ever dreamed of in the real world. The losers get only death. Death terrifies people, and ordinary folk do everything they can to avoid it. But just as the System of the Myriad Heavens' Eerie Domains calls its participants, Challengers. There will always be those who look forward to a challenge.
