Over thirteen years, Zhao Lingyin's master Wu Gong, along with the other alchemists of the Hundred Arts Hall's Medicine King Hall, had also researched the remaining valuable hundred-odd pill formulas in the Outline of Huijue Pill Formulas, including thirty fifth-grade formulas and over seventy formulas below the fifth grade.
