Zhang Bin bargained with the Dragon Vein, and finally reached an agreement.
Twenty thousand top-grade spirit stones in exchange for one person's worth of dragon marrow.
In essence, it means that in the future, when Zhang Bin can refine dragon marrow, he can refine to his heart's content until he can no longer refine it.
If the Taiqing Sect also finds another genius who can refine dragon marrow, they can also refine it. Similarly, it would cost twenty thousand top-grade spirit stones per person.
Both parties were very satisfied with the result.
For Zhang Bin, because he could freely enter and exit the Dragon Blood Forbidden Zone, he could naturally collect countless top-grade spirit stones, so for him, acquiring top-grade spirit stones was no different from acquiring top-grade spirit stones. Hence, he felt he got a great deal.
