Di Jiu could refine eight-patterned grade-seven immortal pills with a middle-grade cauldron. Now that he had a high-grade one, he was certain that he could refine the Seven-Patterned Foundation Elixir, no matter how difficult it was.
Since there were only enough herbs to refine one cauldron of elixir, Di Jiu refined several cauldrons of other grade-seven immortal pills after refining the cauldron, just in case.
Apart from the first cauldron of elixir, which included eight-patterned grade-seven immortal pills, all the other batches of immortal pills that Di Jiu refined were nine-patterned.
This showed that he wasn't lacking in alchemy proficiency or alchemical fire. He just needed a good cauldron.
