In the blink of an eye, it was already August.
Another vacation—of course, it was Severus and Lily's vacation. Manus was busy alone in a corner of the botanical garden.
He had turned this place into an isolation zone, separated not only from the main botanical garden but also with each plot of land isolated from the others.
At this moment, different plants grew in every plot, including both Magical Plants and ordinary plants, as well as fungi. Most of them looked rather strange.
"Eighth-generation Mandrake... cultivation successful. Aside from the top leaves, it possesses a complete humanoid form, but the efficacy of the Mandrake Restorative Draught has not improved significantly."
After finishing the record, Manus sighed.
"Overall, the experiment still failed... Just as expected."
The core of the Mandrake Restorative Draught's effect came from the Mandrake's humanoid characteristics, but it was only after those characteristics became widely recognized that it gained the properties needed to be brewed into Potions.
No matter how human the Mandrakes created by Manus through the Black Earth Technique looked—even if their colors were lifelike—it still could not bring about a qualitative change in that property, nor even any significant improvement.
How should he put it... This Mandrake merely had a much higher margin for error when used to brew restorative draughts. That was all.
Fortunately, Manus, who understood the principles of Potions, had not held out much hope to begin with. He had merely used practice to confirm that this path truly led nowhere.
"Let's stop here with modifying Magical Plants to improve Potion effects. Still, if the Black Earth Technique is used only to directly create existing Magical Plants, it remains extremely useful."
The good news was that Manus would never lack existing Magical Plant ingredients again.
As for Magical Creature ingredients... Well...
