In 2121, a terrible pollution disease swept through the world.

“We call it distortion, but perhaps, the history records of later generations will call it an evolution.”

The world experienced involution.

Today, that person’s head split into two. Tomorrow, that flower would grow fangs. The day after that, that fish would climb ashore with its legs…

Patient A: When I first grew 18 tentacles, I was having a great time eating [beep—] by the seaside. As soon as Dr. Lu came, he cut 17 of them for me. He’s really a brilliant doctor!2

Patient B: I am a poisonous mushroom. My spores are highly toxic and can be parasitic. I gave birth to hundreds of thousands of microspores, which made it worse for my already poor family. Dr. Lu helped me practice family planning when he came. This great kindness will forever be remembered!

Patient C: I have eight mouths. I was a picky eater and only ate meat, so I set up a slaughterhouse for this purpose. But then, Dr. Lu cured my picky eating. This woman of faith is willing to be a vegetarian for the rest of her life in exchange for Dr. Lu’s happiness and well-being in this life.
