Lin Chuan endured the pain in every one of his internal organs and examined the cultivation art the old man had given him.
Each of the ten slots in the Cosmic Light Hall could hold one hundred million spirit stones. Under normal circumstances, the spirit stones in a single slot could provide energy for one month and slow the flow of time by onefold, making a total of tenfold.
After Lin Chuan's Nine Heavens Mystic Jade was embedded in one of the slots, it directly provided an unlimited fivefold time slowdown. Together with the spirit stones in the other nine slots, time now flowed fourteen times slower than outside.
However, that time difference was achieved under normal spirit stone consumption. The cultivation art the old man gave Lin Chuan could accelerate the consumption of spirit stones in exchange for a greater time slowdown, but the consumption was no longer on the same scale as before. Raising the time acceleration by another fold would require far more spirit stones than previously.
Lin Chuan roughly calculated that twenty billion spirit stones, together with the Nine Heavens Mystic Jade, could make time in the Cosmic Light Hall flow twenty times slower than outside for one month. Compared to the current rate, that meant spending an additional 1.1 billion spirit stones in exchange for another sixfold time difference. Any higher than that, and the spirit stone consumption would become terrifyingly high, completely disproportionate to the time gained. It was not worth doing.
By that calculation, even that sixfold time difference was extremely uneconomical. Under normal circumstances, no one would do such a thing; it consumed far too many spirit stones. Not even the Immortal Allure Bu Clan, the richest family in the cultivation world, would dare to spend so extravagantly.
But this was a
