The Old Dragon Kings didn't really mind Nezha's fondness for seafood; after all, they lived in the sea. Guess what they ate?
The other shrimp soldiers and crab generals were about the same. They didn't consider seafood without spiritual wisdom as part of their kin.
They mainly feared Kong Xuan.
After Nezha and Kong Xuan had their fill, they returned to the Western Spirit Mountain.
Currently, Buddhism's operations aren't going well; they're just managing to keep things running. The saying "a man with money commands, a man without struggles" has been true since ancient times.
Running such a large organization like Buddhism requires money everywhere.
People join Buddhism for resources and cultivation techniques, not to live on air.
Old Li's current policies, although not as extreme as when Nezha broke through the formation, do allow taking private jobs and finding some means to earn incense and spiritual materials, as long as no wrongdoing is involved.
