The story tells the story of Xiao Qingchen, the prince of Northern Liang, who stayed in Beijing for three years, kept a low profile, and finally returned with the ancestral sword "Hanjiang", but he was immediately involved in a huge conspiracy sweeping the world. The suspicion of the royal family, the resurgence of the Annihilation Cult, and the appearance of the mysterious "Star Hub" all point to a terrifying plan that can subvert the world - the arrival of "Heart Prison".
In order to protect Beiliang, Xiao Qingchen fought fiercely against powerful enemies in the Wuhui Sea, and finally burned his body on the Star Bridge and sent his soul to the scabbard. His younger brother Xiao Qingyu was forced to grow up and take over the important task. Together with Beimang Princess Tuoba Yue, Jiange Xie Buyan, Tang Clan Tang Lianxing and other close friends, they struggled to survive in the desperate situation of the wasteland where the world was undergoing changes and the black sun was hanging in the sky. Not only do they have to face an endless stream of monsters and madmen, but they also have to resist the whispers of silence that corrode people's hearts, light fires in despair, and guard their hearts in the darkness.
