【Invincible battleship + the main cast travels with the ship + plot-changing System + one heroine + people have their eyes on him + not a goody-two-shoes + not a simp】 【Not a goody-two-shoes! Not a goody-two-shoes! Not a goody-two-shoes! Important things must be said three times! Malicious reviewers, your registrations are wiped clean!】 Oh no! What do I do if I accidentally smash the Going Merry to pieces? Ding! You have changed the plot by 100%. Congratulations, Host, you've received a reward... Luffy, the Arlong Pirates smashed your ship to pieces. I saw it with my own eyes! I know you're in a hurry, but hold on a second. What a coincidence: I happen to have a ship right here... All right! You're a pretty interesting guy, and that ship looks delicious too! Then it's settled. Become my partner, Falgar Lang! Haha... No problem! From this moment on, I'm going to change the plot like crazy! I'll be swimming in rewards!
