Five years ago, the Yun family in Jinling was wiped out. The eldest son, Yun Chen, narrowly escaped death and practiced hard for five years with ten hidden masters, developing peerless martial arts and heaven-defying medical skills. Five years later, he returned powerfully as the young master of the Eternal Life Palace. Faced with Xu Qingyou, his beloved who was waiting for him, he vowed to protect her. Faced with the four major families who were carving up the Yun family's property and the Chen family of Donghai, he attacked decisively, annihilating them all with an invincible attitude, and reviving the Yun Group. After unexpectedly meeting the second senior sister and curing the head of the Dongfang family, Yun Chen pointed his sword at the Zhao family, the real culprit behind the scenes, and vowed to make the enemy pay with blood, starting a journey of revenge for the undefeated dragon.
