One piece: reincarnated as zoro

Jack pov

After killing that marine, I start walking back to the ship to meet vivi but then suddenly I see a guy wearing a straw hat and I instantly realize who that is, I try to walk away from him but he sees me and then come towards me.

Luffy: wanna join my crew

Jack: nah I got my own crew already.

He continues annoying me until I walk away from him,as I keep walking I see as green haired guy and I realize I found a new crew mate, I walk up to him and ask if he wants to join my crew,I ask like I don't know who he was but I know how op his devil fruit, realizing he can be defended since he can basically block most of the strongest attacks.

He tried to attack me but after beating him and his crew up he realizes my strength he instantly accepts my request for him to join my crew,but after we arrive at the ship I realize I need to train my crew or else they will fall behind,so after getting to the ship, I instantly start training barthelomew about observation haki, I was training him on the basics by throwing rocks at him over and over again for a couple weeks and in one of our training sessions he suddenly starts dodging the rocks which makes me happy cause I know he's understood the basics.

I start training vivi next since the navigator still needs to be able to defend herself but surprisingly she learns it way faster than barthomelew.

So after a couple days vivi officially learns observation haki I watch as she jumps on excitement and runs over to hug me thanking me.

I smile and then I tell her to the next island we go.
