Originally, the deep pool was indeed an entrance and exit connected with the outside Cultivation World, and some Spiritual Energy would seep through.
Although this Spiritual Energy was quickly devoured by the Human God Palace, occasionally some was absorbed by the fish in the pool, turning them into what mortals considered Spiritual Fish, which, when eaten, could extend life and strengthen the body.
Therefore, these Spiritual Fish were always regarded as treasures by the major families and even the royal family of Nanxun, who did not permit their private consumption.
However, Chen Dengming certainly didn't care about this. Back when he first started in the Cultivation World, he also spent some time fishing.
The two fish in Chen Jing's hands were actually quite ordinary in the Cultivation World, with no real life-extending effects. Consuming them might strengthen the body, but Nanxun was still incapable of breeding true Spiritual Fish.
