The Celestial Master's Secret Cases: Hundred Ghosts at Night in the Town

Si Tianjian destroyed the family and I was thrown into death row. When he was about to die, the "amber pupil" in his left eye awakened - the iron nail transformed into a spirit and broke out of prison! Cannibalism in ancient paintings, rice crying at night, ghost fetuses in imperial mausoleums... I use the power of enlightening all things to form a "weapon spirit" investigation team to solve the mysterious cases in the capital. Unexpectedly, every murder case points to a century-old conspiracy - someone wants to gather hundreds of extremely resentful souls to turn the world into a ghostland on a dark night. Fortunately, he meets Li Qingyue, an orphan from the previous dynasty. Their swords are facing each other, but they are dependent on each other for life and death. When I revealed my life experience, I realized that I was actually the last "gate" protecting Yin and Yang. The gatekeeper uses his body as a wall. I bet the entire dynasty on this battle!
