The Background Character in an Infinite-Flow Novel Decides to Save Themself

Lu Renjia was a lucky person. Even though he wasn't physically strong, after entering the infinite-flow world, he managed to hold on until the end through brains and good luck. He was also an unlucky person. He died at the final stage, in an utterly ridiculous way: the corpse of the boss, who had fallen from a high-rise before dying, landed on his head and killed him instantly. He was just one step away! One step away from a new life. After Lu Renjia died, he discovered that all these disasters had come from a novel. He saw people observing the world from on high cheering and congratulating each other on the story's ending and the protagonist's victory. No one cared about Lu Renjia, who didn't even have a name, only a codename: "that really good-looking pretty boy." Lu Renjia :) Congratulations, my ass, you MNIX#$%#%$! The world restarted. Lu Renjia dyed his hair white, put on a hood, and leaned against the entrance to the protagonist team's beginner level. He rolled up his sleeves to reveal his lovely arm muscles, struck what he thought was his most handsome pose, and wore an expression that said he had everything under control. Hey, protagonist team, I'm freaking here! Theme: Justice will never be late
