Stop pretending, I'm a security guard, a five-star general!

Everyone says the ultimate goal in life is a government job, but according to him, becoming a security general at eighteen is the pinnacle of his life. He's awakened a life-playing system where he earns rewards for completing system tasks. So, intercepting delivery drivers, beating up troublemakers, and repelling thugs have become his daily routine. Everyone asks, "You're just a security guard, why work so hard?" He shakes his head; a wave of his iron fist and no one dares approach; his keen intuition and no one dares to scheme against him; a five-star general and no one dares to mess with him. Not only that, he's also a popular novelist, a five-star rated delivery driver, a doctor who can bring the dead back to life… "Don't be obsessed with me, I just know a lot!"
