Li Dai had exchanged nearly one hundred million contribution points, effectively trading away almost all the spirit medicine she had grown in her space that was under five thousand years old. As for those over five thousand years old, her space was overflowing with them. After all, one day outside equaled fifty years in the space; one year outside was over eighteen thousand years in the space, and ten years outside amounted to nearly two hundred thousand years within. She was confident that in another few decades or a century, the age of the spirit medicine in her space would reach at least a million years.
This was a terrifying rate of growth. Fortunately, however, the space belonged exclusively to Li Dai. It could not detach from her, nor could it develop into a complete, independent world. Therefore, unless Li Dai willed it so, no matter how aged the spirit herbs and plants became, they would never develop sentience.
Of course, for any type of spirit plant, a higher age naturally meant more potent medicinal effects. However, taking the most basic spirit medicines as an example, even if a first- or second-grade herb reached an age of a million years, there was a limit to its efficacy. Take, for instance, the first-grade Hanzhu Grass; its peak medicinal limit was five thousand years. Even if it continued to grow for longer, a fifty-thousand-year-old Hanzhu Grass would not differ much in effect from a five-thousand-year-old one.
