But the problem lay precisely here. Although the alchemy manual explained when each type of yellow talisman should be inserted, it did not clearly state how many talismans to use or how much spiritual power to put into them! Nor could such things be explained clearly, because no one knew the exact circumstances during a particular pill refinement. These matters could only be judged through experience, and such experience could only be passed down by elders of alchemy sects! Without their instruction, mastering alchemy through blind trial and error alone was exceedingly difficult!
Even a talisman-making Cultivation family like the Fu Family could not grasp it easily, much less Xiao Hua.
Yet Xiao Hua had his own unique methods! As he experimented with sending in yellow talismans and used his perception to observe the changes in the pill liquid, he silently pondered the formulae he had recalled earlier. He also casually formed those formulae with his hands, observing the differences and effects between formulae and yellow talismans! In the course of this contemplation, more new formulae gradually returned to Xiao Hua's memory. In the end, Xiao Hua simply stopped using yellow talismans altogether. He focused on the hand formulae instead, only sending the corresponding yellow talismans into the pill furnace according to the alchemy manual when he truly could not recall a formula!
He fumbled along like this, failing who knew how many times as time slowly passed. Only when the pill liquid within the furnace gradually solidified and the Wutuodan reached the stage of stabilizing the pill did Xiao Hua finally let out a breath. Thinking that he had already spent roughly four days in this abandoned alchemy room, Xiao Hua no longer dared remain there. He sent a formula he had recalled into the pill furnace, then left
