Pseudo-Crossover, Mainly Chinese Paladin, Reverse Transmigration Till the Doomsday of the World

On an unknown date in an unknown month of the year ■■■■, an earthquake accidentally damaged a biochemical research facility in a certain country. The containment room for the Zombie IV biovirus, which was in use, suffered a leak, and none of the researchers survived. Seventeen days later, the Zombie IV virus had spread throughout the country. Nations around the world hastily joined forces to impose a blockade, but it had little effect. The virus has an incubation period and is primarily transmitted through blood. Those infected gradually develop a fear of light, wind, and water, become bloodthirsty and violent, and lose the ability to think. Eventually, they become mindless walking corpses. There is no cure. The United Nations hastily began developing a vaccine, but its headquarters was attacked with nuclear weapons by a person infected with the Zombie IV virus who had not yet completely lost consciousness. The research program was put on hold. Four months later, the Zombie IV virus had spread across the globe. Humanity stood on the brink of extinction. Actually, I wrote this while gripped by nuclear panic. I went to the supermarket to buy groceries and saw the long line for iodized salt. Buying iodized salt may seem a little absurd, but the nuclear threat really is like the Sword of Damocles hanging over our heads. Ever since I was little, I've been told that Japan is just across a narrow stretch of water. As its neighbor, I felt especially frightened at a time like this. I somehow thought of 2012 and wondered, could humanity really be wiped out by nuclear radiation? It seemed strangely similar to the accidental leak of the T-virus in Resident Evil, and I couldn't resist the urge to write this story. I'm scared. I thought that if I wrote it down and turned it into fiction, I might be able to stop taking it seriously and stop panicking. It will be somewhat like Resident Evil, with touches of Silent Hill and Immortal Sword. I'll also borrow a little from FF7. Updates will be irregular. I can't write about truly serious issues, given my limited life experience and writing ability. So it will definitely end up being a Mary Sue story.
