I Used the Post-Mortem Technique of the Song Dynasty to Let Forensic Doctors Around the World Break the Defense

I, Song Ci, traveled through time and became a temporary forensic doctor in a modern police station. On the first day of work, he was faced with a "perfect" corpse that even high-tech instruments were unable to do anything about. The doctors and experts frowned, and I silently took out the vinegar and scallion pancakes. All the forensic doctors in the room looked at me as if they were a madman. It wasn't until I used the principle of "steaming bones to detect injuries" to smoke out the toxins from the bone fractures, and used the "blood shadow theory" to deduce the true shape of the murder weapon, that the "irrefutable evidence" captured by the surveillance cameras turned into a joke - they gradually stopped laughing. When a series of unsolved cases were solved one after another, the bald chief medical examiner tugged at his remaining hair, and his world view was completely shattered: "This is unscientific! What is the principle of spectral analysis of your onion cake?!" I calmly put away my "Redress of Wrongs": "Not all knowledge is written in your textbooks." Now, the International Forensic Organization has sent an invitation, hoping that I will reveal the "Oriental secrets". And in front of me, there is an ancient corpse that has not decayed for thousands of years - it seems to be my... Self's remains in my previous life. This time, it seems like the game has gone too far.
