Origin Story
话说太乙真人，一日静坐，忽觉心血来潮，预感弟子哪吒将有意外。果然，不久后，哪吒在陈塘关惹是生非，与龙王三太子发生冲突，闹得天翻地覆。太乙真人顾不得清修，立刻下山，化解了这场风波，并护送哪吒回山。这段故事说明，心血来潮并非毫无缘由，有时预示着将要发生的事情，也提醒人们要重视突发的灵感和预感。
It is said that Taiyi Zhenren, while sitting quietly one day, suddenly felt a surge of inspiration and sensed that his disciple Nezha would have an accident. Sure enough, shortly afterward, Nezha caused trouble in Chentangguan, clashed with the third son of the Dragon King, and caused great chaos. Taiyi Zhenren, unable to continue his cultivation, immediately descended the mountain, resolving the conflict and escorting Nezha back to the mountain. This story illustrates that sudden inspiration is not without reason, sometimes it foreshadows events to come, and reminds us to pay attention to sudden inspiration and premonitions.
