Demon Immortal

This is an ancient cursed place where no living creature can sense the aura of heaven and earth, and is regarded as a land abandoned by the gods. Due to an accident, the two brothers discovered a shocking secret here: it is not that there is no spiritual energy, but that all the spiritual energy has been absorbed by an ancient formation, which is used to suppress a taboo object that can reverse immortals and demons. The gears of fate thus begin to turn... Humans, immortals, and demons can only become immortals with a thought. Immortal cultivators fall into the path of demons, demons become enlightened and become immortals with just one thought, and people become demons and immortals at will.
