Starting Demon Lord: Do I Have to Join This Bad Class?

Su Yan traveled through the world of immortality and aspired to be a famous and upright family and shine the lintel of his family. After going through all kinds of hardships and passing the "Tianyan Sect" entry examination, I was told, "Congratulations! You have been admitted to the 'Demon Abyss' system on a merit-based basis and will immediately take up the position of intern demon master in the 'Black Wind Ridge Demon Cave'!" The worldview collapsed before his eyes: Immortal sect and demonic path, are they just two major functions of running the world? The Immortal Alliance is responsible for spiritual energy production and "civilization upgrading"? Mo Yuan is responsible for creating chaos, stress testing and resource recovery? Both sides are positions of heaven and one is indispensable! Su Yan's Demon Lord career starts with hell-level KPIs: Monthly Panic Indicator: Scaring mortals to tears counts as performance! Stress test indicators: To attract righteous disciples to clear copies, the casualty rate cannot be high or low! Resource recycling indicators: alchemy waste, expired talisman water, battlefield garbage... All are expensive... No, free recycling! The salary is pure magic yuan, the benefits include five insurances and one fund, promotions depend on work reports, and performance deductions will be made if you fish for fish! Su Yan has KPI in his left hand and cool operations in his right hand. Under the pursuit of the righteous genius, the offensive of the scroll king by the fellow demon lord, and the cold assessment of the heavenly HR... Su Yan has only one simple wish: to keep her job and get off work on time! By the way, The balance of this world is broken. Who is the evil boss behind the scenes?
