The presiding guardian's Alchemy Arts had not reached the ninth grade, but he was still a top-tier eighth-grade alchemist who had studied Alchemy Arts for tens of thousands of years.
Yet when he saw Lu Ren take out Dragon Blood Blazing Fire Grass and Frost Immortal Grass and stuff them into the Pill Furnace, he was utterly stunned. He had never seen any pill that required these two ingredients.
Still, he did not dwell on it. Perhaps Lu Ren was desperately clutching at straws.

Lu Ren did not panic. With a grasp of his palm, he summoned a strand of World Extinguishing Ember Flame and tossed it into the Pill Furnace.

"I hope nothing goes wrong!"
Lu Ren said in a deep voice.

Time slowly passed.
