I Make Crazy Money in the Fairy and Demon Battlefield

My dad said: Stop fighting, fighting wastes your life. Make more money and you can hire people to fight. I am the son of a debt-escape demon, and I was born with countless debts. To do this, I have to work hard to make money. Until one day, I can pay back all the money my dad owes me. Or crush all my dad's creditors. So even when I get to the battlefield of immortals and demons, I have no interest in practicing. I just want to make money, and keep making money. This novel and its characters are purely fictitious.
