No Problem
This test was one designed by a Perfect Sky God, but considering there didn't seem to be a cultivation limit, the tests were instead designed by the level of the person in question. Once the test realized that Ryu was in the Immortal Ring Realm, it likewise properly adjusted itself and the tasks Ryu received were slotted in to be at this level.
Up until now, Ryu had relied on Selheira to deal with the combat aspects of this trial, not to mention his own expertise as a Ruin Master, but now it required his skill in potion making, something that he didn't find too difficult at all.
The first few tasks were simply Common Grade potions, and from what Ryu could tell, he would receive a pass so long as he managed to hit 75%.
