Jellyfish Calamity

Thousands of years ago, a natural disaster struck Blue Star. An asteroid impact that lasted two and a half years pushed the planet 40 million kilometers closer to the sun. Volcanoes erupted, the environment changed dramatically, and the oceans evaporated... More than 99.9% of the life on Blue Star went extinct forever. Only the humans who had taken refuge underground in time managed to survive. Years later, however, humanity was horrified to discover that a group of the most primitive organisms had miraculously survived on the surface, and had even become part of the disaster. They were the "jellyfish." Shi Ming had once been a hot-blooded young man who swore to exterminate every jellyfish and lead humanity back to the surface. Now, though, he was a laid-back CEO who clocked in and out on time. He had a happy marriage, a stable life, and no mortgage. He thought things would stay that way, until one day he got a call from the Special Security Bureau. "Mr. Shi, your husband Yin Jiu was injured in the head by members of a terrorist organization at the seafood wholesale market. Please come right away!" Shi Ming's hand jerked, and he accidentally crushed the thermos of goji berry tea he was holding. ***Bonus scene*** A certain someone with a damaged brain glared at him. "You bastard! You put a vicious curse on me that turned the skin below my neck purple just to keep me by your side!" Shi Ming: "..." You half-blood purple person, that's your natural skin color, okay?!! - Retired powerhouse with max combat ability, bottom VS mixed-blood purple person who can do anything, top - PS: 1. An unconventional post-apocalyptic sci-fi story, with a mountain of original worldbuilding. 2. One-on-one, both virgins, mutually doting, mainly from the bottom's perspective. 3. If you spot a bug, feel free to call me out in the comments. Theme: The many ways people live under different external conditions.
