From Substitute Sacrifice to Ruthless Debt Collector!

The Saintess wants to borrow the Ice Skin and Jade Bones cultivation art from me? The demoness wants to borrow the Heaven-Devouring Devil Art and claim the title of Demon Ancestor? The Empress wants to borrow the War God Atlas? As the Dao-Lending Master, Bu Youtian can unilaterally draw up blood contracts for lending the Dao. When the time is up, he automatically collects what is owed, and you don't get to back out! So he made these lending agreements: Saintess, you have to help me cultivate! Demoness, you have to make me feel like I'm floating on air! Empress, you have to kneel before me and call me Emperor! And one rule applies to everyone: whenever you break through to a new realm, you must repay me half your cultivation! As the saying goes, no one knows of a thousand years of borrowing the Dao, but once it is repaid, I become invincible! Bu Youtian transmigrated into a condemned prisoner chosen to die in someone else's place, and unexpectedly became the Heaven-Ordained Dao-Lending Master. Peerless arts, wondrous Dao, spiritual roots, immortal bones, luck, and opportunities: if you dare sign a blood contract to borrow the Dao, he dares lend it. Throughout his long journey of cultivation, he never once worked hard at training. He simply lent the Dao on ruthless terms to the prodigies of every race, and before he knew it, he had become invincible! One day, he suddenly remembered that there seemed to be one last borrower who still hadn't repaid what they owed. “The repayment date has arrived. Dao Ancestor, repay what you owe!” The Dao Ancestor roared, “I have endured thirty-five million Chaos Tribulations and achieved eternal life. How dare you demand repayment from me?” Bu Youtian pulled out the blood contract and softly called him by his childhood nickname: “Ergou, remember when you knelt in that muddy ditch and begged me to lend you your Dao Foundation?” The Dao Ancestor who had ruled the ages immediately fell to his knees! With the Heavenly Dao as witness and the contract as proof, even a Dao Ancestor must repay what he owes!
