The Plane Store is a truly bizarre existence; as long as it's something that can be sold and bought, you can find it here. At least when Su Jiameng was browsing the Plane Store, she saw a lot of shameless stuff. For example, underwear used by Li Bai, old clothes worn by Du Fu, and even the seminal fluid of a Divine Monarch from a Cultivation Plane! Did they think the Plane Store was a sperm bank?
Given all the above, Su Jiameng thought adding an item named "Mother Tree Main Rod" shouldn't be too much.
Of course, given the Mother Tree's immense power, she didn't want some little brat to buy this and wreak havoc on another plane, so she had to cut off all its life force before tossing it into the Plane Store to await appraisal and sale.
This resulted in a young girl, known as a shrewd merchant on a certain plane many years later, harboring deep resentment towards the dead Mother Tree.
