It Reasonable for Me to Have Countless Guards in an Auction House?

(Semi-Taoist + Auction House + Summoning + Fantasy) Upon waking up, Yang An discovered that he had encountered a legendary time-travel event and arrived in a magnificent fantasy world. Furthermore, it grants access to a supreme auction house system. But this damn system of mine seems to be a little different. Who says an auction house can only be an auction house? I am the master of the Supreme Auction House, the mastermind of the All Heavens Merchant Guild, the mastermind behind the Heavenly Court, the creator of the Underworld, and the greatest merchant in the Three Thousand Dao Domains—Emperor An Tian! What? You think you can enter my auction house without an invitation? Go away, can't you see I'm busy? Yang An waved his hand. Then the music started, and then the dancing began. This is the story of a protagonist who is in deep danger and struggles step by step with his own system. If it is not well written, please be gentle with your criticism. It is not entirely about hiding one's true abilities, but it also has its hidden strengths.
