The Strongest Ancestor of All Realms

An old monster who has lived for 30,000 years has regained his youth and calls himself his ancestor when he meets people. Qin Zheng, the Holy Lord of Tongtian, was besieged, lost all his cultivation, reverted back to his youth, and fell to a continent with barren spiritual energy. Whenever someone claims to be an ancestor, if they don't accept it, they will be beaten directly. In the end, calling Qin Zheng his ancestor became a symbol of strength, and those who are not strong are not qualified!
