Scientific Cultivation of Immortality: Starting from the Dungeon

Until I discovered that there was a spiritual vein hidden in the rocks of the dungeon. Until I met the girl who had been delivering medicine for three years. Until I heard the voice of the sword soul - "Sign this contract and I will lend you my life." After three years in the dungeon, the wall was broken. Lin family, are you ready?
