The Seven-Leaf Brocade Grass from Lord Beiyuan Family's possession was a gift from the imperial family.
This kind of treasure is coveted by all, for a single item could represent an Innate Expert.
Lord Beiyuan himself was reluctant to part with it, as it could truly be said to be an heirloom treasure.
However, he was ultimately an ennobled figure, different from ordinary clans.
If such an item were in the hands of those clans, it could ensure the continuation of the family line; even if the family fell into decline, they could eventually rise again with its aid.
But as a member of the ennobled hierarchy, so long as he made no missteps, the continuation of his family line was assured. Similar treasures could turn up at any time—like this one, bestowed by the royal family.
It's like an heirloom antique that to ordinary folks is a lifeline, which when they are in dire straits they can sell to finance a resurgence.
