Luffy, how can you become the Pirate King if you don't work hard!

Luffy picked up the pendant that had altered the timeline, still looking cheerful. He hadn't expected the so-called Pirate King training system he had activated to be so ruthless.
"Sleep only one hour a day, and any lack of focus will result in an electric shock punishment!"
"When I learned to multitask and painstakingly squeezed out time, I was able to sleep for six hours that night! But then I dreamt that I had to practice math all day! Who taught me math?"
"You ask me who my teachers are? Zoro, Mihawk, Dorry and Brogy, Crocodile... Even the Admirals can come and be my sparring partners. The Seven Warlords of the Sea are the lowest tier."
"My teachers during the day are usually Nami, Vivi, Robin, and Hancock..."
"Master Kaido? Who's that? Don't even try to get close to me, everything I have is a result of my own actions!"
Marineford War.
Seeing Luffy descend with all three types of Haki, Akainu was filled with impotent rage, shouting, "Impossible! Absolutely impossible!"
Luffy drew his Supreme Grade Sword, entered Gear 5 Nikka mode, and his attack was covered in Conqueror's Haki. "Enough talk, take this!"
The war ended, and Luffy heard the warning sound in his ear again, feeling like crying but unable to shed a tear.
"When will I become the Pirate King?"
Plan: Luffy, how can you become the Pirate King if you don't pull a fast one!
