Traveling to the Foot of the Deep Mountains, I Relied on the Mountains to Counterattack

Mu Yun traveled through time! When she died on a mission, her soul traveled to the body of a thin girl named Mu Yun in a small village at the foot of the Qinling Mountains, the largest mountain range in the Kingdom of Apocalypse, a huge mountain range spanning the central and northern parts of the country. The little girl's parents are dead. She has an elderly grandma and brother at home, and a young sister. What should I do if my family is old, weak, sick, disabled, and impoverished? Don't be afraid. In his previous life, Mu Yun, as the last heir of the ancient martial arts family, went hunting in the mountains, fished in the rivers, and even farmed with the folks in Mujia Village to get rich. Seeing that the good days were coming, the dissolute and unscrupulous rulers of the Apocalypse Dynasty did not let them go. They either collect exorbitant taxes or recruit men, or even bring people to blatantly rob them. Mu Yun, her double sword and jade-faced Rakshasa, couldn't stand it! With one turn, he took the whole village with him, and joined forces with the ascetic general Gu Wenqian to bring peace to the troubled times and restore a peaceful and prosperous era to the people!
