America: I'm a Cultivator, Not a Psychopathic Killer

[No System + One Man, One Path + No Harem] Zhang Lingxu thought he had a bit of bad luck. Back then, he transmigrated to a cultivation world for no apparent reason, without being given a System or a golden finger. His life was so miserable he was practically reduced to selling his body. After trying every possible method for over a thousand years, he finally reached the late stages of the Golden Core realm, just a hair's breadth away from Nascent Soul, only to be branded a demonic cultivator by the so-called righteous sects. Then the righteous cultivators surrounded him and attacked him as a demonic cultivator, sending him back to Blue Star. He thought that with his experience as a Golden Core grand cultivator and his cultivation techniques, he would soar to great heights this time, with the Great Dao within reach. But Blue Star's spiritual energy was practically nonexistent... (Note: The protagonist is indeed a demonic cultivator, but he's not some deranged serial killer. If you want a dark demonic cultivator with no limits, this isn't the book for you!)
