Black Emperor Ointment!
Unranked Elixir!
It sounds strange, but in reality, it's not.
In the Immortal Cultivation World, there are quite a few rare elixirs that belong to the unranked category.
Of course, this is not to say that Black Emperor Ointment is inferior; rather, its rank is not fixed.
The rank of the elixir is not determined by the pill formula itself, but by the limitations of the main material!
In other words, the better the main material, the higher the rank of the Black Emperor Ointment that can be refined.
According to the pill formula given by Han Zhan, a First Order main material can be used to refine a Second Order Black Emperor Ointment, a Second Order main material can refine a Third Order Black Emperor Ointment, and as for the Fourth Order Level Black Emperor Ointment, it requires at least a Third Order main material for successful refinement.
What is the main material for Black Emperor Ointment, you ask?
