After checking the attributes of the Ancient Secret Medicine (Improved), Su Xiao was quite surprised. Because he had taken the addition of spirit particles and the production cost into consideration, he had drastically weakened the Ancient Secret Medicine's initial effects. When a human drank this potion, it could restore only 21% of their health—roughly equivalent to a Green Quality potion.
It was precisely this drastic reduction that greatly lowered the production cost. At present, producing one bottle of Ancient Secret Medicine (Improved) required about 80–100 points of Mana. With sufficient proficiency, the Mana required for each batch could even be reduced to around 60–80 points.
With Su Xiao's Mana maximum reaching 6,076 points, as long as he had enough time and sufficient materials, he could produce nearly a hundred bottles of this potion in a short period.
The materials were indeed not the core issue. The core was compressing the spirit particles into a semisolid state. If the Devour Core had not broken through its maximum level twice in succession, Su Xiao would not have been able to accomplish this either.
When a Bleach character drank the Ancient Secret Medicine (Improved), its restorative effect was four times stronger. That was already a considerable amount of healing. Moreover, drinking this substance could permanently enhance their Reiatsu.

If everything went smoothly, Su Xiao could even give the Bleach characters the illusion that this potion could increase Reiatsu without limit. If that happened, he was not afraid that the Bleach characters of the Soul Society would refuse to
