I Open a Courier Station in the Underworld

At one o'clock in the morning, Lin Ye, an unemployed young man, received an employment notice from the underworld - he became a "Yin and Yang Courier", delivering express delivery to ghosts who died in vain, with resentment, and with obsession. A three-year-late apology letter dissipated the resentment of a female student who jumped from a building; a real-name report letter cleared up the injustice of a migrant worker whose body had been buried for three years; half a love pendant gave the bride in red an answer to her twenty-year wait; a peace charm allowed a girl who had been trapped in a dry well for twenty years to finally "go home"... For each completed order, Lin Ye can obtain Yin De rewards and unlock magical powers such as night vision, ghost speech, and loyal soul protection. But as the express station's business gets better and better, he discovers that his grandfather's death was no accident - the underworld judge code-named "Yu Jun" is controlling the dark transactions between the Yin and Yang worlds. When his grandfather's remnant soul blocked the fatal blow for him, and when the three Yin Spirit Jade Pendants were finally gathered together, Lin Ye grasped the Yin and Yang Spirit Ruler and stepped into the gap between the Yin and Yang worlds: "Grandpa has guarded justice all his life, and I will guard it."
