I Bought the Villains With Money

[If more than three people doubt the death, the soul will be saved.]
I was betrayed by my uncle and my trusted lover and stood in front of the guillotine.
Even if I die, I swore to avenge my enemies and sharpened my blade of revenge.
“I, Cassion Richte Petrora, cannot accept Diana’s death.”
I had my head decapitated, and when I opened my eyes, I returned to my 13 years old self.
I made a vow as I shed tears of joy.
“The revenge I was planning to avenge in hell, I will give it to you in this lifetime.”
***
The only thing I had was money, and what I didn’t have was people.
So, I gathered people with money…
“Let’s poison him, *cough*. You have a lot of money, so you can handle that, right?”
Said the twisted sickly prince,
“Are you sure you want to save the body? Can I open it?”
Said the doctor who was crazy about anatomy,
“Just give me the information. If you could do that, I will do anything for you.”
Said the clueless aunt who had no sense of justice and conscience, Zoe, in the presence of information.
“Be my disciple.”
Even the best con artist on the continent wanted to make me his disciple.
Somehow, I only gathered people who smelled like villains.
Will I be able to get my revenge on my enemies safely?
