Great Navigation: Rebuilding the Glory of the Navy!

Cooper travels through the world of pirates. Loaded with the most powerful sit-up system - the will will never die and the fight will not stop! Not only can Luffy do unlimited sit-ups to restore blue and health, but so can I, Cooper! And you can get rewards by completing system tasks: three-color domineering, sword and sword skills, magical powers... Watch Cooper start as a second lieutenant in the navy and single-handedly change the pattern of the entire pirate world! … Akainu: "Cooper is more suitable to be a Marine Admiral than me." Kizaru: "It's so scary. Cooper can catch up with my speed of light with his body~" Teacher Kai: "Is this guy immortal? Maybe he is the strongest creature." Whitebeard: "I have a hunch that this man may end the era of great pirates!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
