joy who had killed baldy , recieved his bounty from marine officer. He had started killing more pirates and recieved their bounties. joy was killing only those pirates who had done crimes like raping , killing , burning towns and other crimes like that.
joy was killing pirates not for fun , but he had a purpose . Yes a purpose . According to system if joy killed nearly 77 pirates with bounties ( even if bounty is only 50 belli it can be counted) he will get special privilege of choosing a nickname for himself which will be spread worldwide. If joy ever got a bounty he will get that nickname that he chooses for himself . And right now he was killing pirates on four seas ( North blue , South blue , East blue and West blue ) for that purpose. Joy was taking full advantage of transportaion skill by using it to go to other seas.
When joy geats near an island he get off from his ship and store the ship in his inventory which then present itself in inventory like (🚢) this. While joy was killing pirates here and there on seas his name was spread in four seas and nearly all pirates and bounty hunters were aware of his name. Since most of them has not saw him , they does not know how he looks but gave him a nickname of " mask devil " because he was wearing the red mask with long white teeth outside of it's mouth and two black little horns.And because those people who saw him were all killed (except garp and luffy . and the villagers of fuusha village has forgot him because he was small at that time and whenever he visited the village for some reason he had put the mask at that time , and navy soldiers also had not saw his face ,so basically no one had saw him)
Joy had saw jonny and zoro but had not met with them since they had not seen his face therefore they does not know him.Right now joy was on an island of North blue. he was training . joy was thinking " although i am strong but it is due to system and i myself had not train very much because without the help of training i may have been only level 20 or 30 right now. and i don't know the origin of system , i also don't know , the system will leave me or not , so it is better to prepare myself beforehand. " . since joy is very precautios person therefore he was thinking far into the future . he also has an advantage because he knows what will happen in the future . joy was thinking how to save Ace and whitebeared . well he can save both of them directly but that will change the plot . Although joy does not give a s*** about butterfly effect but still he is concerned if it will effect the power,strength of luffy since Ace will be saved then luffy will no longer be thinking of training.
Joy was thinking of going to THAT place and he will deal with the problems that come in the future after that .
Joy = system how much transportation is left.
System = joy you have only two transportation left and there is still 11 hours left for it to be full.
joy = Ok system transport me to THAT place.
System = what THAT place , just imagine it and you will reach there.
joy = system you don't understand , i am creating suspense. don't you know suspense.
System = okay okay just do what you want.
joy started imagining THAT place and then
WHOOSH
joy disappear and reappear somewhere on Grandline. OF COURSE AT THAT PLACE .
