There is a Sword Fairy by the Dilapidated Lake

The protagonist Ning Qing happened to catch up with the overthrow of her family after traveling through time. He was formerly a down-and-out dandy. He relied on calculations, leverage, maneuvering, and risking his life to escape. He fled to a foreign land with a group of remaining tribesmen, seeking to survive in the cracks between the clan, the court, and the aristocratic family. Fortunately, he possesses the rare treasure "Lingzhi Zhizhi", which can instantly refine the essence of plants and trees to feed his own cultivation. There is also a strange space hidden in his body that can cultivate spiritual fields and nourish spiritual intelligence, which finally gives him the confidence to make a comeback. It wasn't until he touched the sword that he truly found what he wanted to do. The whole book contains the opportunities, cultivation, and killings that should be expected in a fairy tale, but also the tension of family survival, conspiracy in troubled times, and taking advantage of the situation to break the situation. That year, a broken house came to the Poluo Lake. From then on, there was much happiness in the world and few gods in the sky.
