The Things That the Demon King from Another World Begged Me to Take Him Away from Me

It was just me doing nothing in my previous life, but in this life, time travel actually turned me into a ball? Surprises come one after another. I have maxed out my magical skills at the beginning, killed the strongest demon god, harvested heaven-defying props, infinitely improved levels, and countless wealth. If I want to jump off a cliff to hunt for treasure, it is my destiny. As I walk on the road, wealth will come rolling in! The mythical beast is my mount, the demon king is my little brother, and the son of destiny is my toy. When my country is established, I will become the king and emperor. If you want a strong attack, all you need to do is use your little brother to destroy the country with one ride and break the sky with one sword. This novel and its characters are purely fictitious.
