There were three main steps to refining pills.

Tempering, condensation, and living beings.

Tempering was to burn spiritual herbs with fire and refine them into spiritual liquid.

The condensation was to control the temperature of the flames and then condense the spiritual liquid into the shape of a pill.

As for living beings, they were the last and most important step. They would give birth to spirituality on the condensed medicinal pills.

Only pills with higher spirituality would have higher grades.

It was said that the legendary immortal-grade spirit pills had the same spirituality as humans and could even transform into humans.

Of course, the current Li Hao definitely could not refine an immortal-grade spirit pill.
