46 Nie Li’s master?

As of now, the only soul enhancing pills that Gu Yan and bunch can refine is called the Soul Assembling Pill, and the effect is extremely limited. Those three soul enhancing pills that Nie Li just listed have already been long lost. Their effects are more than ten times or even several hundreds of times better than the Soul Assembling Pill.

In the Sacred Empire Era, Soul Assembling Pill was one of the low-grade elixirs. Soul Nurturing Pill was an intermediate grade elixir, it’s effect is ten times greater than the Soul Assembling Pill. Soul Concentrating Pill is a high-grade elixir, whose effect is at least a hundred times greater than the Soul Assembling Pill. As for the Soul Tempering Pill, it’s a top rated pill. Its effect is at least a thousand times more effective than the Soul Assembling Pill. Even Legend rank Demon Spiritists would get an effect out of it.
