I Mine Other People’s Spirit Bones to Become the Supreme of the Immortal Dao

On the first day after I transmigrated, someone dug out the index finger on my right hand. They forced me to take a knife and carve up other people’s bones. My hands shook like I had Parkinson’s. Luckily, I was bound to the [Life System]. Whenever I removed a spirit bone and transplanted it into someone else, I gained ten times their cultivation speed. And so, the man-eating West Tower became my personal mine. The team leader wanted to dig up my secret? I gave him a bone, and he cultivated on my behalf. The supervisor wanted to use me as a consumable? I took him out and became the boss. The spirit-blood master sister next door wanted to drain me dry? ...Well, let me borrow that marrow bone too. Later, the whole Kingdom of Delusion was fighting over the spirit bones I produced, but no one knew that the crazier they fought, the closer I came to becoming the Supreme.
