Xuanhuan: I Can Sacrifice Anything

Yi Qingchen transmigrates to a fantasy world. His divine blood is stolen and his cultivation crippled, but he awakens the Altar System.

Sacrifice a secret technique, and he masters it instantly.

Sacrifice a pill recipe, and he instantly learns alchemy.

Can't beat an enemy? The System lets him borrow against his future. He can kill them first, then make a sacrifice.

Yi Qingchen: “System, I have this strange feeling that even sacrificing a rock could make me stronger.”

System: “That's not a feeling. It's true.”
