Su Chenbi, the son-in-law of a sick man in the Age of Dharma, accidentally activated the golden finger of the "deduction simulator" by touching his fiancée Luo Zhaoming's personal jade, which also awakened the remnant soul of the ancient immortal that was sleeping in his body. From being forced into marriage to showing their sincerity to each other, the two used their powers of deduction to decipher ancient ruins and suppress disasters in troubled times, while also uncovering the cause and effect of Luo Zhaoming's remnant soul and Su Chenbi's past life - it turned out that he was once a quasi-sage Taoist couple who fell in the great catastrophe, and she reincarnated her remnant soul for seven lives just to help him regain his path to enlightenment. The exciting points focus on the deduction of skills to overcome difficulties in seconds, the Taoist couple joining forces to crush powerful enemies, loving each other in the past and present life, and finally joining hands to re-establish the ancient order and become the supreme heavenly partner.
