The story takes place in the last years of the fictional Dasheng Dynasty - rituals have collapsed, Yin Qi has become stronger, corpses are hidden in the court, and mysterious cases are spreading all over the world. Hua Qianshu, a young man, was originally an unknown flower farmer at the foot of Qingwu Mountain. He was unusually left-handed and alienated by his tribe. Once when he was digging up the soil to plant chrysanthemums, he dug out an ancient tree species that was as black as ink and had blood-like veins. After planting it, it blossomed into a crimson flower with floating petals. Not only does this flower not wither, it can also connect to the underworld, allowing the soul of the deceased to temporarily stay in the world of the sun and reveal the true words before death. As a result, he was involved in a series of unsolved cases: the annihilation of the Cao Gang, the sudden death of the stargazer of the Qintian Prison, and the collective loss of speech of the guardians of the imperial mausoleum... As his psychic skills became more and more advanced, he discovered that each murder case pointed to the "Zuo Family Burning Temple Case" twenty years ago - and the inside of his left wrist was branded with a dark gold seal with the same pattern as the roots of the other shore flower. The main plot is to use the flower as a guide, trace the soul to solve the case, and seek revenge against the fate. Finally, it is revealed that the flower on the other side is actually the ancient "Judge's Wood", and the Zuo family was originally the contract holder of the Netherworld Division in the human world.
