My Spirit Root Is Up for Rent

One hundred and twenty years after the spiritual qi revival, spiritual roots have become the most valuable asset of the age. The rich rent roots to cultivate immortality; the poor sell theirs to pay off their debts. Xu Guitian was born with a top-grade spiritual root, yet he is so poor he can only rent it out. No one knows that his spiritual root keeps a ledger. Every bit of cultivation his renters gain and every technique they comprehend is copied exactly and returned to him when the lease expires. Talented prodigies cultivate for him, sects pass on their techniques for him, and powerful families shower him with resources. This generation of renters is working very hard.
