Yang Shi wished for utilizing the potency of the Soul Nourishing Pill to its maximum. So, he forged some silver needles. However, these are not ordinary silver needles.
They are made from Profound Silver ores, which are used as supplementary materials while forging True grade weapons.
However, equipment made from purely Profound Silver ore isn't much powerful compared to even spirit grade weapons.
Yang Shi forged thirty six needles, each of them was like strands of hair. Although their attacking capability is low. Yang Shi made them for different purposes.
Yang Shi started to inscribe rank one talisman as he circulated his soul qi. He made talismans till his soul qi was almost depleted. When he saw his soul qi was depleted completely, he stopped making talismans.
