Young Zhang Chu accidentally traveled to the country of monsters in "The Classic of Mountains and Seas" and was surrounded by three beautiful monsters at the beginning. The old Zao tree appeared and gave him divine power, and he was regarded as the leader of the village by the old Zao tree. Relying on his interpretation of the ancient sacred book "The Great Wilderness Sutra", Zhang Chu has since led Zaoye Village on the road to cultivating immortality. He took Tong Qingshan and Xiao Putao as his disciples and led them to practice, and experienced strange legendary stories of the demon ruins along the way. The demon treasure is a kind of demon elixir that contains the essence of the demon, which can improve people's cultivation. Zhang Chu and his party obtained treasures, ate demon treasures, and opened life wells along the way, until they reached a forbidden area where the legendary demon king fought. Zhang Chu gradually revealed the secret of his own bloodline.
