Devil's System

One day Joseph woke up with a weird device on his wrist that allowed him to have another chance at life. That device allowed him to finally understand how the world worked.

There were many people throughout history who saw their dreams become true after signing contracts, striking deals with the devil.

And so Joseph will go from a normal student to the very Devil that can make any dream come true.....As long as you can pay of course.

Warning: The Mc will have a system, he will also have a harem. I'm saying this because I know that many people hate those stuff, but given that the MC is a common guy with common wants, a wish-fullfilling system and a harem is only logical.

I will also post this story on Royal Road.
