There's a Catch to the Immortal Sect

Song Yang transmigrated to a cultivation world, but he had no spiritual root. Fortunately, at the age of twelve, he obtained an incredible System. As long as he completed the tasks it assigned, he would receive all kinds of rewards, including spiritual roots. The only problem was that the spiritual roots he received were a little strange. “Junior Brother, your light spiritual root is really useful. Can I borrow it too?” “Sure. One mid-grade spirit stone per day.” “Junior Brother, here's two mid-grade spirit stones. Take them.” Once he had the money, Song Yang provided excellent service, inserting the spiritual root into his senior brother's body.
