Wang Erniu was struck by a purple thunder at the beginning of the founding of the Ming Dynasty and traveled to the fairyland mentioned by his master Zhang Sanfeng. In this world, there are thirty-six Taoist caves and seventy-two blessed lands, as well as the Buddhist kingdom, the underworld, the demon world, and the demonic realm. Wang Erniu relied on the various Taoist spells taught by Zhang Sanfeng to develop invincibly in this world.
