Wo De Yingzi Hui Guaji

By chance, Li Yunmu found a supercomputer from humanity’s dark ages. After that, his pathetic life would never be the same! Aptitude? Talent? Who needs those? I have neither aptitude nor talent, but my shadow can keep grinding experience for me in real life even when I'm away. XP, mana, weapon mastery……. all of them could be hacked, so I'm gaining experience even while I'm asleep.
