Heaven is not a fairyland, but an "involved" society: Heaven is not the free and easy life we imagined, but a huge institution with strict hierarchies, complex processes, and full of "fairy KPIs" and "celestial bureaucracy." Immortals also have worries, gossip, office politics, and even a "996" work system (such as guarding the Nantian Gate, patrolling the Milky Way, etc.).
Takeout is a "dimensionality reduction attack" on the "mortal world": food in the mortal world is a luxury product for gods. Because although the "immortal meal" in heaven can replenish mana, it tastes the same and extremely unpalatable. A spicy and fragrant Sichuan dish is a supreme enjoyment for an immortal who has been in heaven for five hundred years. Take a look at how the delivery boy Chen Fan shuttles back and forth between the mortal world and the heavenly world.
