Special forces soldier Cheng Ruoming bears a blood feud and hides under the assumed name Shen Yan in Dunhuang. On the night the Cheng household in Jiangnan was massacred ten years ago, his father, Cheng Zhuo, gave his life to protect him and embedded a bronze mirror engraved with the mysteries of the universe in his palm. The mysterious old man Lao Chaofeng forged him into a "rock," tempering him into a blade of vengeance.
When fragments of the bronze mirror turn up at the Yonggu Arsenal, a Japanese curse inscribed with the words "Sakura scatter, the road does not return" reveals the first glimpse of a conspiracy. The Seven-Star Spiral Formation in an old Huizhou residence nearly crushes him to death. The Taoist master Xuyun of Longhu Mountain helps him purge the evil force inside the mirror, but in doing so exposes an even deadlier danger: the star-core seed within him is being eroded by the taint of the Star Abyss.
The final battle unfolds at the Eye of the Guixu Sea. Facing the dimensional projection of the Star Abyss's master, Cheng Ruoming burns his body and soul, using his star core to ignite the power of corruption. The will of three generations of guardians awakens inside the bronze mirror, and the Cheng bloodline pierces through time and space like a blazing chain. As the mirror's evil god shrieks and shatters amid the starlight, he uses his mortal body as a torch to cut away the universe's festering darkness, turning filth into the fire of a reborn galaxy.
At last, he returns to Dunhuang with his newly awakened star core. In the twilight over the sea of sand, the star mark in his palm pulses in sync with the mirror's glow. The young man sheds the armor of hatred and becomes a sky-watcher who commands the star charts of civilization. Where a lone column of smoke rises straight from the desert, a new cosmic epic begins to stir like shifting grains of sand.
