Ling'er taught Ye Mo five unique second order seals. Among them, three of them could only be refined by those in the second order seventh tier, one could only be refined by those in the second order eight tier, and one that could only be refined by second order ninth tier.
Ye Mo was able to easily refine the first three seals. The mortal gate in his brain was capable of sustaining the backlash from the seals when he was refining them. He was not very confident in the next two seals. He failed one time after another, nearly finishing up the heart-stones he had in his Dimensional Bracelet. Ye Mo was forced to go to the League Points Hall to exchange his points for some heart-stones.
