The East Sea Dragon King now was really scratching his head; although their Dragon Palace had better things, they couldn't bear to part with them. You have to know that their Dragon Palace has to pay tribute to the Ancestor Dragon Hall every year, and after that period of repeated 'cooperation' with Nezha, their family wealth really wasn't much.
As Ao Longwang was troubled, the voice of Suan Ni came to his ear.
Suan Ni's message was simple: Isn't there a piece of Divine Iron left by Dayu for measuring seawater in the depths of the East Sea? Introduce this to him; this object is full of spirituality, and you can just send him off with it.
Do you think Suan Ni, this fourth brother, is being kind by giving this idea? Wrong!
