A secret Empire program that improves agents' physical capabilities and pheromone levels through drug injections. Xie Ren participated starting at age 14, receiving injections three times per week for over 600 total. Side effects include severe pain, high fever, muscle spasms, pheromone instability, and extreme rut period instability. Of 37 experimental subjects, only Xie Ren survived; the other 36 died from organ failure, pheromone rampage, or nervous system collapse.
