In his past life, the Lingxiao Sword Emperor accidentally was reincarnated as the young man Chen Bahuang. With the help of the mysterious supreme treasure Hunyuan Book, he re-started his cultivation and embarked on a journey to find the truth behind his family's old case. Facing successive trials, he resolved difficult problems by virtue of his wisdom, courage, and swordsmanship experience, and also learned trust and responsibility amidst the support of partners such as Ji Mingyue and Xuanyuan Jiuge. All the way from Qingcheng to the Great Zhou Academy and Hantian Mountain, he continuously guarded his companions, broke through himself, finally forged the Tier 9 Lingxiao Sword, and discovered that a broader mystery still awaited revelation.
