I Am the Little Master's Uncle

Who I am? Where am I? Oh, right! I am the great uncle of Lingyun Sect! The great uncle of Master Rehu who was just dug up from the grave of his ancestor. Ling Fengchen, who came from Blue Star, became a disciple of a cultivator. When he was twenty years old, he blocked a fatal attack for his senior brother. He was seriously injured and on the verge of death. Finally, he was sealed away by his master for eternity. When he wakes up again, eternity has passed and everything in the past has become dust, but he has become the great uncle of the sect. Although this is nothing. But something is still wrong. Why was it that the sect was wiped out as soon as it was dug out? ! Crooked? To be honest, apart from the sealed years, I have only been in this world for twenty years! What should I do? Waiting online, quite urgent.
