At the awakening ceremony, Su He discovers that his bloodline is sealed by mysterious bronze markings, leaving his cultivation stuck at the third level of Body Tempering and putting him at risk of being cast out by his family. On the night of the full moon, an ancient bronze mirror left behind by his mother reveals strange Dao patterns. A young man resembling Su He appears in the mirror, hinting at the truth behind the bloodline seal.
After failing the test, Su He discovers the entrance to a hidden realm behind a waterfall in the rear mountains, guided there by the ancient mirror. The same Dao patterns as those in the mirror are carved into the stone wall, and his bloodline produces a strange resonance. When Su He touches the core of the hidden realm, the bronze mirror suddenly draws three drops of blood from his heart. A blood-red star chart appears on its surface, and a rare celestial phenomenon of nine stars aligning emerges above Qingzhou City.
