Cells at War: I Became a Cell in Another World

What if your body was a feudal empire at war? Transmigrated into the microscopic Cells at Work universe, our hero discovers a shocking truth: organs are kingdoms, cells are citizens, and humanity itself is just a cog in an alien bio-factory. As a humble cell navigating the Heart Kingdom and Liver Duchy, he must fight pathogen invasions, crush cancer cell rebellions, and unravel the cosmic conspiracy—Earth is merely an immune cell in a higher-dimensional being's body, and we're all neurons in something far greater. The human empire's survival depends on one cell's awakening.
