The second most important resource that he could buy was crystals. Crystals were an important cultivation resource for Tiki, Dreyer, and even himself.
They needed to use crystals to progress in their immortal cultivation and to practice witchcraft. As the main source of strength for Tiki and Dreyer, Yoze didn't want them to face any hurdles that would slow them down.
And the most important hurdle that Yoze was able to get rid of was the lack of crystals. Before he had even received the money from the Thorn Rose Sect Tiki and Dreyer didn't have much to worry about when it came to the number of crystals since he had enough money.
But Yoze still felt that it was better to buy a huge amount of crystals now for a few reasons. The first was that buying the crystals now would not negatively affect them and instead would allow them not to worry about buying crystals in the future when they needed them.
