The Most Powerful Upgrade System in History

Have you ever seen someone kill a chicken and reveal a god-level bloodline? Have you ever seen a toad-killer reveal divine martial arts? Have you ever seen women all over the world go crazy for a man like him? With the dragon-slaying knife on his shoulder and the sword of the gods in his hand, I just asked, "Fuck, who else?" Long Fei, an otaku, traveled through time with a violent system. Killing monsters and killing people also upgraded, crushing the three realms and destroying all those who disobeyed!
