Time-Travel Dad

The main protagonist of this work is the father. He worked hard for the family for most of his life, but he was tortured by illness and died in the last half of his life, leaving behind three children and a wife. Neither of the children got married, and one already had a child, but he died before he could enjoy the joy of being a grandfather. When he left, Dad unknowingly went to a place where souls should not go. He practiced there for an unknown amount of time, and finally got a prototype. It turned out that it was the residence of a hermit master who cultivated immortality. He accidentally broke into that place and understood their conversation about cultivating immortals, so he had the opportunity to complete the prototype. Later, when the ghosts came to catch him, he went through a lot of hardships and wanted to return to the world just for that unfulfilled wish. He accidentally traveled through time when he jumped down from the reincarnation gate. . . This novel and its characters are purely fictitious.
