In The Multiverse With Two Golden Fingers!

Lionel suddenly woke up in a strange forest, with no memories of his previous life except for his personal name, he realized that he was reincarnated!
Want to know why did he realize he was reincarnated?
He still keeps all his memories of all the novels, fanfics, manga, and manhwa that he read, even the anime and Marvel movies are still in his mind so that they have become very clear because his mind is empty of everything else other than them.

[You have obtained the 'Destiny Steal System' main system]
[Ding!]
[You've got the 'dimensional chat group' subsystem]
Suddenly he heard a mechanical sound in his mind, making his mind blank.
(The novel will be a multiverse, the first world is One Piece, the second world is against the gods, I haven't decided the rest yet)
{There's a really huge harem here, so if that's not your interest just don't read on}
