I Deliver Food to Slay Demons

I, Yan Siye, am twenty years old, an orphan, and my profession is a delivery rider. It was dusk that day, and I was ordered by the platform to bring a bowl of Malatang to the ancient temple of the City God. Unexpectedly, the clay-gold body actually said: "Young man, you have strange bones and three flowers looming on your head. You are truly a unique talent for cultivating immortals!" I lowered my head in confusion, but saw the note in the order clearly written: "Add more spicy food, more coriander, and no green onions, thank you. - The ancestor you have never met before paused."
