Weird, my gaming life

[Bizarre - ruthless - no female lead - plentiful content - all plot holes will be filled]
Reborn into a bizarre world, abandoned by her biological mother and reborn as an orphan.
This is a world dominated by aristocratic bloodlines, where the bizarre and unpredictable run rampant.
Because Lin Yuan did not have the bloodline of a noble family, he could not become an Awakener. His mother had to choose between two options, and he returned to the orphanage.
He should have had a miserable life, but because of his innate ability to enter dreams while fully conscious, he entered a game called "The Great Jianghu" from his previous life, becoming an NPC native with a built-in system panel, and was able to return to reality with the martial arts skills from the game world.
Reality: You monster, I knew you weren't human a long time ago, so quickly reveal your true form.
Hmm... Koi Fish Mystery, what kind of mystery is that? Is it the koi fish I know?
Rebirth is a mystery – is it a cheat code or something else? For a moment, Lin Yuan was completely confused!
The various protagonists' cheat abilities from the novels I read in my past life have now transformed into all sorts of bizarre phenomena in this world, and they have begun to coexist with the chosen awakened ones in a strange manner.
Am I the only one with a cheat ability...?
