Although the public auction had ended, the private negotiations had just begun. However, these were no longer Ye Wudao's concern; they were matters for the Dostone Clan.
All Ye Wudao needed to do was ensure the safety of James and the Fallen Angel Cross in his possession in Hua Country before the negotiations reached an outcome.
The European Lion Knight Order, originally there to target Ye Wudao, now abruptly redirected their aim to prepare against James. James, unless he was a fool, would understand that the Lion Knight Order wouldn't allow him to safely bring the Fallen Angel Cross back to Europe. They would surely try to deal with him in Hua Country before he could return to Europe with the item. Once back in Europe, they would lose any chance to confront him.
