With a Piece of Contract, I Will Settle the Cause and Effect with the Wealthy Family

Ten years ago, grandpa lost his Taoist foundation and used forbidden magic to save the Qin family from extinction. The two parties signed a contract and promised that when the Qin family became prosperous, they would betroth their granddaughter Qin Ruxue of the same age to Tang Fuling and share one-third of the family property. Many years later, the Qin family violated the contract and treated Tang Fuling coldly when they came to visit with the contract. Ridicule, prevarication, betrayal... Retribution soon followed. Since people's hearts are not trustworthy, then use the mysterious way to settle the cause and effect! Tang Fuling used the art of looking at the earth and observing the Qi, tearing apart the illusion of grandeur, and arousing evil spirits in the mansion... Tang Fuling will get back everything she promised in the past...
