One Piece: Starting as a Marine Lieutenant, I Slack Off and Get Stronger

[Naval faction, satirical style, enjoyable read, reasonable] Question: What should I do if I accidentally transmigrate to the world of One Piece, where pirates run rampant and war is raging?
A: Join the Navy! Paid training, monthly income over 10,000 RMB; a large platform with fast promotion opportunities;
Accommodation and meals provided, transportation (on a warship), backed by the World Government, stable job, working until 99 is not a dream! Navy Headquarters Lieutenant Carl stated that the above situation is basically true, but it does nothing to stop him from slacking off! Who told him he has a slacking-off system, where he can become stronger by slacking off every day!
