When a Mortal Cultivates Immortality, I Will First Deceive and Then Sneak Attack

Cultivation + no system + no harem + decisive killing + caution + no invincibility. This is my first time writing an article about evil cultivators and I try to keep my three views in mind. The content is dark and dark, so if you don't like it, don't read it. Wang Teng traveled through time and became Wang Teng, but it was not my son Wang Teng who had the qualifications of an emperor. As the worst time traveler, the moment he was caught by the evil cultivator, he was destined not to become a mortal. From then on, he was born as a cruel, murderous, and cautious old devil.
