Kill the Boss at the Beginning, but Then You Can Only Pretend to Be X.

The male protagonist accidentally traveled through time and wanted to be the second generation ancestor. But he didn't want to meet an enemy who would take advantage of the death of the family ancestor to seek revenge and destroy the family. The male protagonist awakens the system but finds that his ancestor is not dead, and he wants to refine the entire clan and make himself an immortal. He relied on his intelligence and wisdom to balance his ancestors and his enemies, and then caused them both to fall. Unexpectedly, he was considered by all parties to be the person who had taken away the body of the ancestor, so he was involved in the trend of great changes in gods, immortals, demons, ghosts and demons, and had to deal with it several times.
