This novel is adapted from the Chinese popular animated film Ne Zha: Mo Tong Jiang Shi. In the beginning of the world, a powerful Primordial Pearl was born from the spiritual energy of heaven and earth. The Celestial Venerable Yuanshi refined the Primordial Pearl into a Spiritual Pearl and a Demon Pill. The Spiritual Pearl was meant to be reincarnated into a human who could assist in the war against the Shang Dynasty and bring great benefits. However, the Demon Pill would give birth to a demon king that would cause great chaos in the world. The Celestial Venerable Yuanshi activated the Heavenly Tribulation Curse, stating that after three years, a heavenly thunder would descend to destroy the Demon Pill. Taiyi was ordered to let the Spiritual Pearl be reincarnated into Ne Zha, the son of Li Jing in Chentangguan. But by a twist of fate, the Spiritual Pearl and the Demon Pill were swapped. Ne Zha, who was supposed to be a hero with the Spiritual Pearl, became a mischievous and powerful demon. Despite his naughty and unruly behavior, Ne Zha had a heart longing to be a hero. However, facing the misunderstandings of the people who saw him as a demon because of the Demon Pill, and the approaching heavenly thunder, was Ne Zha doomed to become a real demon? What path would he choose?
