Transmigrating into the calamity of Journey to the West, he is reborn as an unknown little demon in the mountains. He knows full well that Journey to the West is ordained by Heaven, and that most little demons cannot escape death during the tribulation. By chance, he awakens the Delay-to-Get-Strong System: the longer he holds up the pilgrimage team, the stronger his cultivation and supernatural abilities become. He has no interest in Tang Monk's flesh and devotes himself to obstructing the pilgrimage party. Under the watchful eyes of gods and Buddhas across the heavens, one little demon throws the entire Journey to the West into chaos.
