Pirate's Full-level General

In 1462 of the Haiyuan Calendar, the 13-year-old Youdian entered the school at the same time as Karp Warring States, and then he was hanged and beaten in the training camp of the Navy Headquarters.
In this world of talent and Devil Fruit, all Youdian can rely on is the sweat of hard work and the system.
'Ding!The host also needs to run 10 laps around the naval headquarters, and the six-style-shaved can reach the full level! '
'Ding!The host also needs to poke the stone 100 million times with his finger, and the six-style-finger gun can reach the full level! '
...
'Ding!The host also needs to smash 1 mountains with armed-colored domineering fists, and armed-colored domineering can reach full level! '
'Ding!Host...'
Listening to the system's repeated prompts and the ** cultivation task, You Dian only felt a lot of pressure!
However, when he defeated Whitebeard with one punch, and the fist wind blew away the golden lion, and the fist force shocked Roger, only then did he realize that the practice that was comparable to hell in the past was indeed very valuable.
