The Wood Divine Thunder is fine; Yang Zhenshan has cultivated the Qinghua Thunder Skill, allowing him to freely use the Qinghua Thunder Pearl to unleash the Wood Divine Thunder.
However, the True Sun Fire is not the same; his True Sun Fire comes from the Golden Crow Eight Trigrams Furnace, and he himself does not possess the True Sun Fire. He can only unleash it by using the fire seed of the Golden Crow Eight Trigrams Furnace.
This also means that when using the True Sun Fire, he needs the cooperation of the Golden Crow.
In terms of energy operation, this adds an extra step, requiring perfect coordination between him and the Golden Crow.
Of course, there are benefits too. With the Thunder Fire Spear, Yang Zhenshan can fight using the True Sun Fire without the Golden Crow having to charge recklessly.
