Don't Mess with the Delivery Guy, I'm the Immortal Master of the Immortal Realm

A fairy from the fairy world fell into modern times and started delivering takeaways in order to survive. He shrinks down to deliver food, cooks elixirs in a rice cooker, and draws talismans to ward off evil spirits. His appearance and ability are both outstanding, and he has become popular all over the Internet! He works in a low-key manner to cultivate immortal power, and in a high-profile manner suppresses evil and destroys enemies. The delivery boy is actually a big boss in the fairy world!
