Lou Wuye was shocked by what this person with Yun Ming's face was talking about. But just based on the reaction of this young Yun Ming, Lou Wuye knew that they did not have the same timeline. After looking closely at the kind of prison he was in he had remembered reading this type of prison. This is owned by that notorious race. The Ye Guis.
They made an underground water prison where the Ye Guis would torment the traitor of the clan. The main element of the Ye Guis race is fire, being soaked in water for a long time weakens them greatly and affects their cultivation. Not only would it result in regression in strength, but his fire element would also be converted to water. Once that happens then his Ye Gui Bloodline would disappear completely and he would be exiled with less lifespan as punishment.
