Lin Fan traveled through the fantasy world and became the "Holy Ancestor of the Human Race", but he was a scumbag with no cultivation. He wanted to run away, but was shocked to find that his disciples and grandsons were all "imaginary monsters"! All his mistakes and lies were imagined into an inscrutable plan. As a result, the most incompetent fake ancestor in history was forced to start an invincible legend that relied entirely on acting skills and luck with the assistance of a group of "fairy teammates".
