Crown of the Underworld CU

He, who had it all, fell into a trap but also through space and time, losing his life to gain a new one as the light of a new dawn fell upon him, as glorious as his past life has been. And so he shouted his first cry.

From the famous and respected young emperor of the largest empire in the continent Uzar which tamed the silver dragons and built the largest magic academies to a world of... "science and technology" ?

"What... what is this sorcery !? Where are my dragons ! ahh!"
In a nursery, a three and half years old boy named Charles and nicknamed Charlie, cries in anger holding on a book "Imaginary creatures".
He looked around watched the other children playing around and the adults observing him with amusement.
' I want to go home... it's already been so long and tried but magic keep failing. '
Clutching his little hands into fist, raised them and shouted.
" Fine ! If it is so, I shall conquer this world too !"
'But how... that is the question. And then, I must return home.'
Laughter could suddenly be heard around him. The adults couldn't resist. It was a funny little kid indeed. But a young girl looked at him in confusion yet awe before smiling.

Seven years later, he knew how. A translucent window suddenly appeared before his eyes as he took his first step down the stairs. Unluckily for him, he regained consciousness in the hospitable with a broken left arm. However, the window was still there.
' What's this ? Magic ? no... a system. What's a system ? ah ! What's this, Stats ? Charm 32 ! Charming I am indeed ! Quite true. Intelligence 9... Wut ? '
And the title of the system was "Reach the top". He then finally smiled and laughed startling the nurse that came to check on him.
' What's wrong with the kid !? He didn't seem to have a concusion.'

So who has killed him and throw him into this bizarre world and why ? What will he do ? Will he suceed ? How long will he take to return to avenge himself ?

P.S. : It's a parallel world of ours. Some things are the same, others aren't.
