This is a matter that cannot be changed anymore. Over a month ago, when discussing Princess Weisaiya's marriage, Beirong had already sent an envoy with a dowry, which is now almost reaching the capital.
It is normal for the Beirong Prince to leave now. After all, Princess Weisaiya and King Qi's wedding still requires a month, and at this time, rumors in the imperial court suggest opening trade with Beirong.
Such a significant matter requires the Beirong Prince to return and consult with the Beirong Emperor.
However, just as he was preparing to leave, he heard about the auction. Upon learning it was about a new loom technology from the Chu family's weaving workshop, the Beirong Prince immediately sent someone to investigate.
After receiving confirmed information, he directly dispatched a close subordinate official to stay behind and personally attend the auction for the loom, while he needed to return first and then hurry back.
