he was sure he atlest needs these many people and he had not considered eating a devil fruit or not.

he than think he needs a ship and a lot of money then he think what type of weapon he should choose then after some time he was sure he will use guns because he knew the design of guns so he start working under a blacksmith to learn ow to make guns and sword he was young he was only 15 in that body .

time skip 1 year .............

know he had enough money a to buy metariels and know how to use iron and other metals and he had bought enough gunpoweder that he can keep shouting for there years

so he start making guns and all type of guns like::::::

M82 SNIPER

M90 SNIPER

RUGER SUPER BLACKHAWK (PISTOL )

AKM

BENELLI M4

it took 6 months him make these guns and suitable ammos and sufficient ammos for than he failed many times but didn't stop.

===============================================================

know its time to hunt he took three guns from his secret locations on gone after bounty of pirates.

those were (AKM , BENELLI M4 , GRENADE LAUNCHER ,AND FEW GRENADES ) they was heavy but he has become strong after 1 year and 6 months of blacksmithing and 6 months of gun traning.

his first target was soon bunch of losser . he was sure he can beat them because he can use basic armament haki and observation haki.

he then collects information about local pirates and find about there hideouts .

first was a pirates called red skull pirates caption of those pirates have a medium size of shipe almost little big than merry and bounty of 4 million and some money about 1 million so he just go in front of gate of these pirates hiding his guns under cap and guns was on his back

then he just take out there grenades and trow them on ground neer pirates after removing there pins and he just need to wait for 30 sec and it will be boom but when pirates see him they started to badmought him and asking him why he is here

so in response he bring out his akm and start shouting randomly until he hears bang of grenades he thrown at them .....(it was just awful there was hundred of people some without hand some without legs due to immense power of his haki filled gun ...........

and then he saw truth he saw two ladies in a cage almost looking mother and daughter carrying and terfied from him and pirates .

pov mc

i think this should be enough then what should I do with these girls .

lets see

James - hi

duo of mother and daughter - pl___ease ple___ase don't kill ous i will do anything

James was not a good or bad person and he need a crew so he asked duo

james - will you join my crew

duo -- w__hat what

James - join my crew I am a pirate till know I am alone but I will get many people in future

duo - (frightened) o______________k ok

James - open the cage and ask name of duo

duo - my name is rose and she is my big sister lily is daughter lily his mother died while giving heart to her so she had same name has his mother

James - oh lily you can call me big bro ok

lily - ok big bro

james so collect anything those pirates have which can be sold and take there money until that time I will go and cash the captain of these pirtaes ok

after 3 hours

james returns and saw them complete there work so he says come with me and he pick the things

which the duo collected he than goes and sell all the things in market and take them to cloths shop and give them some new cloths which look more like pirates so afterthat they buy soon raw materials and returnto his house then rose goes to make some food

after some time they eat food rose was a very nice cook he was happy .

then the next day he told the duo his name is james and hand over two guns two them

rose - no we don't need them

james - if you are pirate you should be strong enough to protect yourselves

rose was still uncomfortable around him seeing other day how he killed hundred of man alone so she don't resist any of his orders

rose got GLOCK G17 and lily got RUGER SUPER BLACKHAWK they both was shocked they had never had sean any gun like them

james - lets start practising

duo - o__k

after 12 days .......

they was all ready they had a ship of red skull pirates they had removed his flag and it and that place of flag was empty

rose - what will be our flag

james - not now we are not strong enough to protect ourselves if we had fight in sea

rose - ok

they had collected all the guns and necesory supplies

they then started the sailying until these time rose and lily had become comfortable around him

so after 2 days of sailing they didn't see any island and was worried then james think he don't know how to use ship and navigate he was fully dependent on rose

he was sure he need a sailing master .
