As the sun began to set, casting long shadows over Ryo's base, he stepped outside to check on the water tank and solar panels. The evening air was cool, with a light breeze rustling the leaves, but something else caught his attention: the persistent presence of the female zombie. She followed him wherever he went, like a shadow glued to his every step.
Ryo stopped near the water tank, glancing back to see her standing a few paces behind him. Her pale skin seemed to glow in the fading light, and her white eyes watched him intently. She never made a sound, only following as if bound to him by some unseen force.
He sighed, feeling a mixture of intrigue and annoyance. "You're not going to leave me alone, are you?" he muttered under his breath. But deep down, he knew this was part of the experiment's success. The question was, how much more could she evolve? Would she become even faster, smarter, or maybe more dangerous?
