Although it is not a Divine Grade item, a Holy Grade Ultimate is extremely precious to Pei Kuang.
It's essential to know that although the Qianwang Holy Tower possesses Holy-grade cultivation methods and Martial Skills, they are merely Holy-grade Middle and Low-level. Now, obtaining a Holy Grade Ultimate all at once, of course, allows his power to ascend to a new level.
It doesn't mean that Holy-grade items cannot reach the Divine Martial Stage...
Any cultivation technique can possibly allow someone to cultivate to the Divine Martial realm; it's just that the weaker the technique, the greater the difficulty. As Lady Li would say, in the vastness of Canghai Wujiang, there are many who have cultivated to the Divine Martial Stage using Holy-grade Ultimate techniques.
