Heavenly Gate served as the bridge between Heavenly City and the Mortal World, and under normal circumstances, entry and exit required strict review—at minimum, one needed a nod from a Martial Arts True Immortal like Bai Fen to descend.
"Heavenly People might not be just servants of the Martial Arts True Immortals, they could have other uses, like food resources?"
Gu Shanhai quickly made comparisons and found that the cost of maintaining these Heavenly People far exceeded the benefits themselves; it was almost like charity.
If these Martial Arts True Immortals were into charity, they wouldn't have established Heavenly City.
Thus, their actions seemed to Gu Shanhai like raising chickens and ducks.
The cost of villagers raising their own chickens and ducks surpassed that of buying them from the market, but why do they do it? On one hand, the animals can lay eggs, and on the other hand, they are tastier and safer to eat.
