Hua Ci was currently at the Spirit Stream battlefield, and her cultivation had reached her own limits with no way to improve further, which is why she repeatedly lowered her own cultivation to refine the Ten Thousand Poisons Bead.
The potency of the Ten Thousand Poisons Beads' toxicity was not only related to the amount of cultivation Hua Ci had expended during their refinement but also connected to the potency of the poisons she ingested.
The first time Hua Ci gave Lu Ye the Ten Thousand Poisons Beads, she was not yet familiar with this technique and considered it practice, and to prevent Lu Ye from detecting anything suspicious and becoming unnecessarily worried, she did not expend too much cultivation.
But as the number of Ten Thousand Poisons Beads she refined increased, she became more proficient in the process.
This time, the Ten Thousand Poisons Beads that Lu Ye received had undoubtedly involved the expenditure of much more of Hua Ci's cultivation than before.
