After Everyone in the Village Became a Star, I Was Forced to Become Invincible

The heroine is born into the cultivation world and adopted by simple village folk. For sixteen years, she studies and practices farming skills with great diligence. Only when she leaves the village to seek her origins and "gain experience," slicing the Demon Venerable into the air with a single sword, does she realize in horror that the village hunter uncle is a retired Sword God, the old medicine lady is an ancient Alchemy Saint, and the "farming manual" and "pig-raising fist" they taught her are actually supreme Dao arts lost to the ages.
