I Turn into Bluestone to Suppress Evil Spirits, and All My Descendants Will Be the Sixth Child

A world of immortality polluted by "deceitful ways". Traditional immortal cultivators can easily go crazy and become monsters. They can only stay sane by relying on "foreign objects" (such as magic weapons, formations, and strange beasts). I traveled through time and became a dilapidated stone tablet at the door of a cultivating immortal family. In order not to be sold as waste stone, I could only consecrate stray dogs and beggars passing by. Unexpectedly, hundreds of years later, my "descendants" would become the most feared "old six" army in the cultivating world.
