You are a person who has been reincarnated into another world. This world is filled with magic, monsters, etc. Your curiosity of this world has turned yourself to become a genius in this world, but because of your unsated curiosity, your mind starts to shift.
During your time at the academy, you were considered to be a kind and great student, excelling at everything, but the truth is, you have secretly killed some people, from adventurers to mage, to study them during your day off at the academy. You experiment on many things such as monsters, dragons, stones, and even humans. This goes on until you turn 35 years old.
You had a successful career and was given a noble rank, and you have secretly built a huge name for your self within the criminal society, and you have even built a huge organization that could rival a kingdom military strength. When you were experimenting on some human underground, you were caught by the authority and were sentenced to death. After that, you are deemed to be the most evil person ever.
People thought you were dead, but you've actually transferred your consciousness into another clone of you that you created. Your full memory and knowledge are still fully intact to yourself. You then continue your experiment. This goes on for around 700 years. Even though you lived that long, you still have to swap your consciousness multiple times to another clone before your body rots. You've also got caught multiple times and are sentenced to death multiple times.
During those 700 years, you've gained strength and power and were even managed to control an entire kingdom from the shadow. The strength that you gained from those 700 years is the peak of human strength in that world, but the knowledge and wit that you own could rival those of gods. With those strengths, you have experimented with ancient monsters, fairies, demigod, lesser god, etc. You've also created many incredibly strong underlings, many identities for youself, from doctors, teacher, professor, merchant, mercenaries, etc, and from those experience, you could disguise yourself perfectly to be come a man, woman, a child, etc.
The current years are 1267. People with fine clothes are walking around the town, guards that are patroling around are carrying their guns, and magics are floating all around the place.
