The Spirit Food formula is Tiger Bone Spirit Ginseng Soup, which can strengthen bones and temper the body. Long-term consumption can enhance physical strength, and if combined with Body Refinement Techniques, the effects are even better.
This is somewhat similar to the Physique Elixir, but since Spirit Food basically has no elixir toxicity and the medicinal effects are mild, it can often be used together with elixirs, doubling the happiness when combined.
What surprised Lu Yi the most was the Spiritual Wine formula.
The name of the Spiritual Wine formula is Concentrating Spirit Dew, a very rare type that can nourish the spirit and enhance spiritual power!
You should know that in the Qi Cultivation Stage, the enhancement of a cultivator's spiritual power is primarily augmented alongside their cultivation base.
Other methods, even those involving Divine Soul cultivation techniques, are not practicable in the Qi Cultivation Realm.
