"I've already defeated the Azure-eyed Golden Monkey Beast, the most likely to be defeated among the Town Mansion Spirit Beasts. It has now been removed from Miao Miao Blue Clothes' challenge options. Now, he can only choose from one of the other five Town Mansion Spirit Beasts and can't possibly do it within a short period. As long as I maintain my leading strength and keep successfully challenging the Town Mansion Spirit Beasts, the Golden Treasury Water Mansion will ultimately fall into my hands!"
This requirement doesn't seem to be particularly difficult, as the Shangxuan Star Sand Sword seems to have been specifically designed for confronting Town Mansion Spirit Beasts.
Although the Shangxuan Emperor Starlight's summoned Six Ding and Six Jia Divine Generals only lasts for a limited time, it is still, as an extremely rare additional spell that grows stronger as the player's level increases, enough to fulfil Ye Rong's requirement within the given time.
