A mortal was selected by the Immortal Sect and was supposed to be a sacrifice for "killing love and ascending to immortality", but before he died, he heard the devil whisper: "It was an immortal who killed your whole family, not a devil." From then on, while using the immortal way to reach the sky, he was pulled by the devil at the same time. Every time he ascends to another realm, he becomes closer to an immortal; every time he sees people's hearts clearly, he becomes more like a devil. Immortals have levels, and the higher the level, the more they disguise themselves as heavenly principles; demons have no levels, only primary and secondary, and whoever can expose people's hearts is the master demon.
