Elder Hai Sheng!

It is impossible to even describe the pain of having one's life force absorbed by the Blood Demon Grand Magic. Only someone who has experienced it could possibly know the feeling. If you had to liken it to something, it would be like having an acidic liquid injected into your veins. As it filled your body, it would melt your flesh and blood, transforming your innards into a shapeless mass.

Then it would be slowly extracted as life force. In this case, Meng Hao acted like a bridge, delivering that life force to Chu Yuyan.

If the Demonic cultivator could cry out right now, it wouldn't lessen the pain, he could at least vent some of the torment he was experiencing. Instead, the pain simply existed in his heart as an undispellable torment.
