Seventeen-year-old Li Luo and Su Xiaotang were preparing to travel around the world on their way back to their family after ten years of Tianheng training. They unexpectedly discovered that Jiulong, which had been sealed by the Six Spirit Gods, broke through the seal. Since the six major families no longer have pure bloodlines, the only way to prevent Jiulong from being used by evil is to sign a contract with Jiulong and become the inscription of a weapon. On the way, he accidentally met Lin Mubai from the light department, Baili Yanhua and others from the fire department, but was accidentally kidnapped by the cult Han Yin and one of the dragons was taken away. At the peak of the decisive battle, Li Luo discovers a shocking secret.
Ten years later, only Su Xiaotang was left clinging to the temple.
