A monthly expenditure of one thousand Lingyu was naturally nothing to Lu Ye. He now had eighty million Lingyu on him, along with quite a few Spirit Crystals. One thousand Lingyu was but a single hair from nine oxen!
But that was merely the cost of cultivating with Lingyu. In truth, his cultivation relied more on the Talent Tree's devouring and refinement. The Lingyu he spent all went toward purchasing Fire Element treasures, and that expense was truly terrifying.
Take his advancement from the mid stage to the late stage, for example. If he had cultivated step by step with Lingyu, Lu Ye estimated that at most he would have used one or two hundred thousand Lingyu.
Yet his actual expenditure had been a full ten million Lingyu—a difference of nearly a hundredfold.
However, Lu Ye had decided to consolidate his cultivation for now and deliberately rein in his progress, so his consumption of Talent Tree fuel would not be too great unless he lost his mind and ventured deeper into the Myriad Phenomena Sea again.
That was basically impossible.
After determining the cost of his current normal cultivation, Lu Ye swept his hand, and all manner of Fire Element treasures immediately piled up beside him in a small mountain.
