I don't think shuhang will use or have any patterns at all , the grades of a golden core are something an Mc would likely completely ignore ,mutate or far surpass .
Fang Ming has the immortal core , Leylin had blackfire nightmare, Fang Yuan had creation etched , Yang Qing had supreme yinyang unity core ,Wang Lu had primal chaos non phase twin unity .. .
Max grade is too average for an Mc ,unless its a darker struggle story like Wang Lin where its barely even average .
I'm rooting for the mystery route for his patterns. He'll be unable to see how many patterns he has since they are hidden under the full plate armour that has become one with his whale.
