Yang Shi mumbled as he planted all herbs in Mystical Roc Garden.
Well, Although these herbs need to be thousand years old for being mature, it doesn't strictly take over a thousand years.
Many things can be a catalyst for the growth of medicinal herbs. For example, the Spring Fertile Soil can reduce the time for the maturity of herbs by one-third.
That means:- a herb, which would have taken one thousand years to mature, will mature in six hundred and sixty seven years. Not to mention, it could be still reduced.
