I Can Become Stronger by Fighting in the Pirate World!

My name is Feng Feifan. When I woke up, I found myself waiting to be shot at the shooting range. The green algae man next to me said that I will become a great swordsman in the future, but I may have to stop here. What about you? Feng Feifan looked confused and didn't know what was going on. He heard the gunshot. A boy with a straw hat stood between the two people and blocked all the bullets. He said, you two look very strong? Be my companion! I am the man who wants to become the Pirate King! At this moment, Feng Feifan is bound to the battle system. As long as he keeps fighting, he will become stronger. He will give a newbie a gift package of the pulls version of the Thunder Fruit that is not afraid of sea water (Anilu's Thunder Fruit will not be affected).
