In Blue Star, Legendary BOSSes are incredibly rare, with most of them located in the deep sea.
Thus, legendary items and equipment are extraordinarily precious.
Don't be fooled by Zi Liyuan's wealth and influence now, in reality, he only possesses a few legendary items. This is an issue of shallow foundations.
Without a family backing him, not a second-generation rich or powerful, relying purely on himself, even if he rises rapidly, he still can't match those families that have accumulated resources for hundreds or even thousands of years.
Even if Zi Liyuan plunders the military's resources and uses Origin Treasure Chests to open treasures, the highest quality of equipment and items he can get is Purple Epic Quality.
While legendary materials indeed can be obtained, turning them into legendary items or equipment requires finding someone capable of crafting them.
Any professionals with such skills are big shots in their own right, and the things they're involved in are numerous.
