I, 68 Years Old, Traveled Through Time and Became the Only Person Who Can Laugh.

I, Shen Qingchen, 68 years old, Emeritus Professor of Anthropology, University of Cambridge. After studying civilization all my life, I thought I had seen it all. Until I traveled to another world - a world where technology is 400 years ahead of the earth, but no one laughs. There is no art, no chit-chat, no tears. All people are implanted with "thought stamps" when they are born, leaving only rationality and eliminating sensibility. Emotions are diseases and need to be "calibrated" regularly. And I am the only one here who can laugh. I wanted to find out the truth, but found that the scientist who invented the steel seal 100 years ago left a diary. The last page said: "Here it comes. It says emotions are an obstacle to evolution. I wanted to go back on my word, but it was too late." Who is it? When I finally found the answer, the being who called himself "The Will of the World" said to me: "You're finally here. I've been waiting 100 years - for someone to clean up this mess."
