The Lucky Star Blessing the Whole Village - Chapter 347 - 343:

Our protagonist Caam is a man from Earth that was reincarnated into this world as a demon. In order to survive, he spared no effort in avoiding the sparks of battle and without noticing it, he became strong himself.

I was forced to live in captivity for the rest of my life because I happened to be aware of the fact that I was a saint. I was truly a ‘real’ saint, but that didn’t matter, because there was already a designated saint in the temple.

When I died from all the abuse I endured, I was sent back to a time before all those previous events in my life had happened. After 15 regressions, I was exhausted. I prayed, “I don’t want anything to do with this, so please just let me die,”

And at that moment when I could finally be able to die, someone said, “How about being my daughter?”

…. That monstrous duke had adopted me.

My past life: Ordinary. Mediocre.

What I want in this life: Riches. Power. Influence.

My goal: To be a prodigal son. A waste youth with riches and power. Maybe even sidekicks.

My name is Ye Lang, I’m an alchemist, and I’m also here to squander as much money as I can.
