Kill the World Flying Immortal

In a desperate world, the lower world is kept in captivity like a pasture by the upper world, and human sacrifices are made every year as a "blood tax." The young man Chen Tie was born into a family of ordinary miners. He numbly endured his fate until the angel arrived and a bloody massacre fell before his eyes, leaving his family in ruins. He was forced to wander, and on the verge of life and death, he accidentally obtained a mysterious bone fragment recording a strange skill, and he embarked on the treacherous path of cultivating immortality. Under the guidance of an old fox-like supporting character, he sneaked in the darkness, struggled in the conspiracy, and gradually gained insight into the cruel truth of the world of cultivation and the conspiracy to monopolize the practice. From an ignorant boy to a serious hero, Chen Tie endured the humiliation and worked hard step by step, vowing to overturn this man-eating world, break the shackles of the sky, avenge blood, and create peace.
