I Slay Demons in a Strange Court

I, a time traveler who was a forensic doctor in my previous life, originally wanted to be a slave in this strange ancient world of immortality. However, due to a sudden death of a prince, I was forced to be involved in the shocking whirlpool of the court and the immortal sect. I use scientific thinking and the cultivation gained from touching corpses to speak out for the wronged souls and eliminate injustice in the world.
