The ancient demon god spent thousands of years cultivating the cursed dark demons, and used the entire city as a sacrifice to open the dark demon realm in an attempt to break through the seal and come to the world. Antique explorer Jackie Chan, Taoist exorcist father, and clever girl Xiaoyu rely on the power of twelve talismans and ancient Taoist exorcisms to resist; at a critical moment, a young man who has been hiding in the city and has inherited the bright armor for generations appears. He restrains the shadow monsters with the pure power of light and shadow, and joins forces with the talisman lineage to defeat the demon carrier of the Holy Lord.
After the war, the two sides saw clearly that each other's strengths were complementary and their goals were the same, and they formally concluded the Talisman-Light and Shadow Eternal Guardian Alliance. They exchanged tokens and divided labor to check and balance the darkness in the world: the Talisman restrained the demonic curse, and the armor purified the dark energy of shadow. Everyone cleaned up the battlefield and set up double seals to eradicate the remnants of the evil spirit. They thought the city had returned to peace, but they didn't know that the Holy Lord's remnants had not been destroyed. He pretended to escape and hid in the mountains, secretly planning a series of sinister plots to alienate the alliance, cultivate monsters, and awaken the eight demons. A hidden and more sinister conspiracy wave was slowly sweeping the entire city.
