OMG! She’s a Real Deity

The ancestor of the Moon Clan is three thousand years old when she wakes from her sleep, and she comes down the mountain for one person. Three hundred years ago someone saved her life, and that person has been reborn. The Ford family in the city has had a bad stretch. The old chairman fell into a coma without warning and there has been one accident after another at the family's construction sites, and people say the Fords have offended something. The eldest grandson remembers what his grandfather told him, that when there is real trouble you go to the Moon Clan village and ask for someone. He half believes it. He climbs into the mountains kneeling every three steps and kowtowing nine times, and brings back a woman who looks under thirty. At the Ford house she takes no tea and no food. She walks once around the construction site, pulls a few nails out as she goes, and the old chairman wakes up. She tells the family that someone has been doing this to them on purpose. A rogue cultivator has his eye on the jade pendant the Fords have passed down for generations. With it and three other tokens he can cut the dragon vein that runs under the city. The family's second son is being used by him, and the chairman's wife takes against the visitor at every turn. She breaks the arrays he lays with the strength of three thousand years of cultivation. When he raids the Moon Clan village she goes back into the forbidden ground and takes back the power she had left there, and for the last fight she sets up the Four Symbols array. Along the way the four great families' sacred objects are recovered.
