If the refining process was done correctly, even becoming an Innate Supreme Treasure was not an impossibility. The mere thought of it excited Xin Yun to the point of not knowing what to do.
Choices like this were in fact quite scarce. Among the better-known examples was the Seven-Leaf Plantain from the Plantain Tree, which was similar to the location of the Red Gourd. There was also the Seven Treasures Wonderful Tree in the hands of Saint Zhun Ti, which was actually an Innate Spirit Root, a branch of the Bodhi Tree, bearing an uncanny resemblance to the Red Gourd!
Regrettably, none of the seven leaves of that Plantain Tree survived to maturity; they were picked by someone before they could. The most mature leaf was only refined into the Plantain Fan, the one in the hands of Princess Iron Fan, which was deemed unworthy by saints and ended up with Minghe Old Ancestor.
