Let You Be Treated as Medicine Dregs, and You Will Kill the Demon Lord?

"In this world of cannibalism, good people don't live long, bad people live tiredly, and only ruthless people can live forever." Shen Lian traveled through time and became a "drug slag" in the Demon Sect's death row, and was forced to practice the life-extending magic skill at the beginning. Fortunately, he awakened the mysterious jade book and had endless longevity. From then on, he embarked on a crazy and magical path of "exchanging his life for his path". … The evil spirit fills the body just to open up the orifices; Corpse bones are used as firewood, just to forge the demonic body; Burning a thousand years of longevity just to swing out that sure-killing sword! … Many years later, when Shen Lian stood at the top of the world of immortality, his feet were covered with bones. Someone asked him: "Old Demon Shen, you have killed countless people in your life, aren't you afraid of being punished by God?" Shen Lian wiped the blood on the knife and said lightly: "God's punishment? I have lived for so long, God has changed me several times, and no one can accept me." "Since I can't take it away, it means... I'm right."
