Necromancer Mixed in with Forensic Medicine

"This body died of homicide. The murder weapon was a single-edged knife about 15cm long. The time of death was between 23:00 and 24:00 last night." An Yin pushed up his glasses and signed the autopsy report. No one knew that the youngest forensic director in Xingjiang City was actually an undead archmage who had traveled from another world. Anduin, the undead monarch who once dominated the Milan plane, is now trapped in this body named "An Yin". Although there is no magic in this world, he found that every time he dissected a corpse, he could absorb weak soul energy. Relying on the spell-casting skills accumulated over thousands of years, he just used a scalpel instead of a staff, used an anatomy room to set up a magic circle, and cast a simplified version of undead spells in this magic-free world. From serial murders to mysterious disappearances, there's no case he can't solve - after all, the dead never lie to him. Until one day, a specially treated corpse was sent to the autopsy room, and even he found the restrictions remaining on the corpse troublesome. When three men in black robes suddenly appeared in the morgue late at night, and when the police department began to investigate his "abnormal crime detection rate," An Yin pushed up his glasses and showed a dangerous smile: "It seems that someone wants to play hide-and-seek with the Necromancer?" "Remember, in this world without magic -" the scalpel rotated on his fingertips, and blue runes appeared on the ground, "I am the only law."
