Pirates' Centenary General

Luo Xiu traveled to the pirate world and brought a system with him. This is a perfect protagonist template! I thought I was going to be awesome, but this system has not been loaded for a hundred years. When Luo Xiu's 100th birthday came, Luo Xiu thought that his time travel would end in vain. But just when he was hoping, the system was finally loaded! With the support of the system, an old man who had been forgotten by the times finally entered the public eye again. Luffy: "Grandpa, how did you practice this fist? Why does it hurt more than grandpa hitting people?! I'm a rubber man!" Whitebeard: "Is this guy really a hundred years old? Why do I feel he is stronger than Kaido?" Garp: "This old man is called Laodang Yizhuang. Compared with the old man, I am simply a scumbag." This novel and its characters are purely fictitious.
