Yue Wen had actually thought before about which Spirit Plant seeds to plant first.
To begin with, he could not grow those supreme natural treasures himself, things like the legendary Nine-Turn Reincarnation Immortal Lotus, Azure Sky Myriad-Age Emperor Grass, True Immortal Coiling Dragon Peach, Supreme Forget-Worry Fruit...
Their growth cycles were measured in tens of thousands of years, sometimes even spanning several spiritual energy eras. Even if Immortal Dew Valley could provide a hundred years of growth in a single year, they would still take centuries to mature.
He only had a few precious planting spots for Spirit Plants right now. If he planted natural treasures with such long growth cycles, who knew where Yue Wen would be making his fortune by the time they matured?
Of course, the most important reason was still that he had no seeds.
Whenever seeds of Spirit Plants of this caliber became available, even if they needed thousands or tens of thousands of years to grow, many sects would treasure them, planting them and tending them carefully to leave for future generations of disciples.
What suited Yue Wen now were plants with growth cycles of less than a hundred years, preferably ones that matured in a few decades or less, so he could see results and reap the rewards within a few months.
The seeds also had to be relatively easy to buy, with publicly available sales channels.
Finally, the Spirit Plants he grew had to be useful. Ideally, they would directly aid his cultivation.
Yue Wen logged onto Treasure Forest's website and browsed their stock of Spirit Plant seeds. After careful selection, he finally chose three varieties suitable for the Black Silver Corpse Puppet to plant.
The first was called Moon Palace Cotton.
This was an Immortal Seed cotton widely cultivated by growers.
