The Great Devil Emperor Development System

One hundred thousand years ago, as humanity rose to power, the new Demon Emperor Xiao Ting and his predecessor faced relentless bullying from the stronger human race, leading to the old Demon Emperor's demise in despair. In his anger, Xiao Ting vows to protect the Demon Emperor Sutra, a precious treasure of the demon clan, and commits to intense cultivation. After a millennium of training, he unexpectedly masters the sutra, advancing from its initial ten floors to an astonishing 99,999. Upon emerging from seclusion, he discovers the “Devil Emperor Development System,” a humble yet quirky system that expresses dismay at Xiao Ting's full-level status, revealing that the tales of new systems being powerful may be misleading.
