Essence is born in the kidneys, blood is born in the spleen, nourished by the five organs and six viscera.
The decoctions Xu Shaohui drank weren't to replenish his essence and blood, but rather had the effect of regenerating them.
However, this effect was not very noticeable, but better than nothing.
Once all the treatments are completed, those medicines will have such a small effect on Xu Shaohui that even the regenerated essence and blood are just a little bit.
Perhaps, they can prolong Xu Shaohui's life by another eight or nine years.
Eight or nine years is actually quite a lot.
The Xu Family used countless medicines on Xu Shaohui over these years, only to keep him alive, like a plant that can't even blink his eyes.
And during these eight to nine years, his body might be somewhat weak, yet he can walk and move like a normal person, completely reversing his fate, thanks mostly to the two rare spirit medicines.
