Luckily, Zhang Cheng has a wicked cultivation System that lets him take life from others to extend his own. But, System, look at this scrawny little kitten. Who can I possibly kill? Does swatting a mosquito count? Yes: one second of extra life. What about slaughtering chickens and butchering fish? Yes: at least a month of extra life. The longer-lived the species, the more life you gain from killing it. What about slaughtering pigs and sheep? Yes: at least a year of extra life. Then... what about bacteria? Get lost... What about cells?… Transmigrated into a Cat: I Have a Wicked Cultivation System for Extending My Life. Come see a cat demon’s rise to glory!
