In the end, Gu Yunzheng still told her the pill formula for the Fiend Suppression Pill. However, the value of this Fiend Suppression Pill wasn't just in the herbs required; it also had to be of a high level, at least at level 6. Pulling out baleful aura was the hardest thing to do. In an era where spiritual energy was depleted, low-level alchemists were hard to come by, to say nothing of alchemists who could produce high-grade pills that could attract a heavenly tribulation. This had never appeared, or had stopped appearing, in the world.
Even for a major family, obtaining high-grade medicinal pills was simply harder than ascending to the heavens.
This was why Gu Yunzheng felt that bringing up the Fiend Suppression Pill was no different from not saying anything.
