The impoverished young Lin Yun embarks on the path of the Spirit Guard to save his younger sister. Every breakthrough comes at a terrible cost: his sworn brother dies in battle, his beloved self-destructs, he kills his sister with his own hands, loses his sight, and suffers a split personality. At last, when he reaches the pinnacle of the Void Realm, he chooses to give up eternal life and use all his power to bring back those he has lost.
