The Most Awesome 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 skills? Have you ever seen women all over the world go crazy for me, Long Fei? With the dragon-slaying knife on his shoulder and the sword of the gods in his hand, this handsome guy would like to ask, if he has experienced harm or not, who else is there?
