I Sell Weird Things in the World

My name is Chen Ping'an, and I am the sixth-generation shopkeeper of the "Wuwu Sheng" medieval shop. This store does not sell anything, it only accepts items. Contain those "concepts" that fell into the world from the cracks of mythology. An elixir that traps people in 996 reincarnations forever; a fish-gut sword that unsheathes itself on a full moon night and goes on a journey; a Nian beast that is so depressed that it swallows the laughter of children because there is no more joy in the world. I thought that my whole life would be so peaceful. Until that day, a customer I couldn't refuse came to my door and handed me a blood-stained pawn ticket. "I heard that you accept everything? Then... The 'gods' forgotten by you humans, do you accept them?" That day, I realized that the store my grandfather left to me contained the last spark of human civilization. And I am the last person responsible for watching it go out or be rekindled.
