Starved By a Fox Spirit, My System Levels Skills Infinitely

Zhang Chen’s life is a nightmare of endless hunger. He's unknowingly been a meal ticket for the beautiful, \"benevolent\" fox spirit next door, who steals his food under the guise of \"repaying a favor,\" leaving him on the brink of starvation. He’s a human battery, fueling her mysterious needs. But when a dropped piece of bacon reveals a hidden \"Golden Finger\" system—a power to pick up points and infinitely upgrade skills from anything (even the fox's pilfered goods)—Zhang Chen's fate irrevocably changes. His first skill, the \"Light of the Righteous God,\" inexplicably hurts the vixen’s soul form, turning his tormentor into his personal XP farm! Now, with the vixen unknowingly supplying him with power, Zhang Chen is hunting for more. He’s found an ancient tomb overflowing with points, but what ancient dangers lie within, and what terrifying truths will he uncover about his 'kind' neighbor's true nature?
