Mr. Shen, Your Fire Magic Is Too Strong! (Seeking Monthly Votes)

Shen Le obediently placed an order with the Special Affairs Bureau for a huge pile of books, guides, and operating manuals on artifact refinement, then worked hard at studying them.

After studying for a while, he finally found a way to refine materials containing Yin-tainted auras into spirit artifacts. There were roughly several possible routes. The first was to saturate them with a larger quantity of Yin-tainted materials, such as blood:
