When heavenly pirates crossed the upward stream to the paradise first half of grand line they met with a big whale which Zack remembered as Laboon in the anime, an island eating whale.
He could also recognize the mark of straw hat pirates badly drawn on it. Now he was sure that the straw hats have also arrived the paradise.
After talking with Crocus who was also a member of pirate king's crew he was sure that straw hats have just entered grandline. So he estimated that they are on there way to arabasta kingdom to overthrow the rebellion happening due to the meddling behind the scenes of crocodile who was also one of the Shichibukai.
After having a little party with crocus they started travelling towards Arabasta kingdom. They didn't need any log pose etc because seiryu was already installed with the map of whole world by Eve, Zack just have to tell it to move and it moves on its own.
"Boss is there any particular reason we are headed towards Arabasta kingdom?" Asked Robin while reading a book.
"It is for you Robin." Zack said.
Robin lifted her head while gazing at Zack and asked "For me?"
"Yes for you and don't ask me anything because it will not be a surprise if i were to tell you in advance." Zack said and closed his eyes and continued to enjoy the soothing rays of sunlight.
Robin looked curious but didn't ask any further because she knew that Zack will not tell him now.
Robing sighed and continued reading her book while enjoying a cup of juice.
********************
After two days in an endless desert Straw hats were moving towards Katorea. Which was now made the base of rebellion army lead by koza. They have rested the previous night in Yuba, which was the previous base of rebel army.
And Vivi had proposed to move to katorea when they learned from Toto that the base was shifted due to the shortages of supplies. So when they started moving towards Katorea luffy who was walking with them suddenly sat down under the tree and didn't move an inch even when the others urged him.
After that there was the argument between luffy and Vivi about why is she carrying the whole burden on her shoulders to which vivi retorted that i have nothing other than my life to bet on.
To which Luffy angrily shouted that "Then bet our life also, because we are FRIENDS."
when he said that vivi started crying.
'Clap Clap Clap.' they suddenly heard clapping sound and turned to see that who was it.
It was none other than Zack who was standing there and clapping.
"ZACK" when strawhats saw who it was they became very surprised and shouted his name well except chopper.
"Good speech and also very good friendship." Zach said while also smiling mischievously. when straw hats were guessing the purpose fo Zack's presence here they say a magnificent ship came flying and stood hovering above them.
"Hey zack why are you here? Luffy asked him again.
"Well why are you here?" Zack questioned him instead of answering him.
"I am here to kick crocodiles ass and stop the rebellion happening in vivi's country." Luffy replied him seriously.
"ooh so that is why you are here. OK so i will also tell you why i am here, but first introduce your new friend to me." Zack said while pointing towards a scared chopper who was learning about the recent adventures of Heavenly pirates. As he listened to nami's explanation he was getting more and more scared of heavenly pirates.
"Oh he is chopper our docter's ship. He is an amazing docter." Replied luffy while also introducing chopper.
"Ok so now it is my turn to tell you that why am i here. Hm~~ let's see ~~ well you can say that i am here to do the opposite of what you wish to do." While saying this Zack suddenly became serious and released a tiny amount of his Haoshukou Haki to intimidate straw hats.
It was totally effective and they became tense.
"What do you mean you bastard." Asked sanji angrilly.
"As you heard me. I am here to take princess vivi to crocodile." Said Zack seriously.
"As if we will let you take her. She is our nakama." Said luffy as he took his fighting stance.
"Heh~ as if you could stop me. You are weak." Replied Zack.
"TRY US!" luffy loudly shouted and all the other members also took their stance. When they were ready to fight, nami usopp and chopper were clearly terrified while the others were also tensed well except luffy who was acting like....well....Luffy?
Because they were clearly aware of the strength of a guy who can easily defeat an admiral. But they still steeled their hearts and prepared to fight.
"Ok so you want to fight me right? Ok so be prepared to die. But you have to first defeat one of my crew member. if you can beat him then i will just leave but if you loose i will take princess to crocodile as well as you might die." Said Zack while also releasing his killing intent.
"Gulp~" Straw hats gulped in unison while cold sweat can be seen running down their faces.
"Ok bring it on." Shouted luffy. While the other straw hats were thinking that 'It is bad seriously bad.'
"DAZ!" Zack called Daz bones. When daz heard Zack he simply jumped down from the ship and came infront of Straw hats.
"Boss are you sure you want me to fight these kids? They may die." Daz turned towards Zack and said.
"Yes of course. Remember in this world if you decide to start a fight then you should be prepared to kill or die." Zack said seriously. His voice was clear as Straw hats also heard that and thay became more nervous.
"Ok so start fight." Said Zack While he backed off.
"Gomu Gomu No Bazuka"
"Ittoryu Unigiri"
As soon as Zack gave space to them luffy and zoro started to attack.
When their attacks landed on Daz's body
"Thud""Tring" these voices came. And luffey and zoro felt like they just attacked an iron plate.
While on the other hand Daz only used tekkai. He didn't feel any thing from their attack.
After that Daz also started attacking them while using his devil fruit.
And this fight can only be described as total and utter devastation for straw hats. Whatever they did had no effect on Daz he was still unharmed. Hell his clothes were also fine.
Straw hats were totally desperate. Danz was originally an assassin so his moves were for fatal injury and this is what happened to all the straw hats they were bleeding from the many heavy cuts Daz inflicted on them. Now they were thinking to run away from here but they knew that it was impossible.
When luffy was again trying to attack Danz he saw Daz running towards Sanji and made his hand into a sharp spear blade and was going to pierce sanji's heart when suddenly something hit Daz on his head sending him flying through the air and then he crashed with a big boulder while the boulder crumbled into pieces due to the force contained in that hit.
When the dust cleared Daz Bonz came out of that debris and say the perpetrator who was responsible for his bleeding mouth. When he saw the perpetrator he said angrily "The hell are you doing Raiju? Why did you interfere.??" Daz was practically fuming in anger.
"You asshole! You want to die? don't you know the one you almost killed is my dear brother?" Raiju replied in such a cold voice that hearing it Daz's anger subsided greatly. He was angry but he was not fool. He knew that if a serious fight started then the one who will probably die will be him, Due to many types of poisons Raiju uses.
While they were arguing strawhats were dumbfounded specially sanji. Because they were not able to put even a scratch on that monster while using full strength, And suddenly someone sent him with a kick on his face while he started bleeding. 'Monsters, they are all monsters.' they all thought.
"Well boss i think this is enough for their lesson. They will die if they lose any more blood." Said Raiju while looking towards Zack. Who Then threw a pouch towards Raju, When she checked it she found senzu beans in it she then put one in sanji's mouth And to the amazement of the straw hats all the injuries of Sanji healed at a visible rate and in some seconds he was as good as new. After which he put those strange beans in his other crew's mouth and they all became totally healthy.
"Follow me to the ship." Said Zack and turned around towards Seiryu who had landed on the desert and with a jump he stood on his deck.
When Straw hats heard them they were a bit hasitent but still followed him to the ship when every one stood infront of him he asked them calmly. "So what do you think would have happened if Daz really wanted to kill you from the start?"
"We would be dead by now." Said zoro because he was aware of the disparity between them.
"Of course you would be dead. So now as you have entered the grand line it is time for you guys to get serious. You guys are not playing pirates here, if you remain weak like this you will die before you know it. So that is why when we arrived arabasta and learned that you are also here i wanted to check how much did you improve. But as i see it you didn't improve much. If you go on in this pace you will definatly die."
Zack told them word by word.
Yes this whole scheme was made by Zack who wanted them to learn the dangers of these seas.
Well he was sure that as the main characters they will be saved by plot armor but now he made some big changes so he was not sure that the plot armor will still work or not.
So to be on the safe side he took actions on his own.
When he finished speaking the straw hats faces were full of determination. They were really considering Zack's words and knew that he was right so they promised themselves that they will now seriously start training even the cowardly trio were filled with determination.
"Ok that is enough of serious talk lets eat something and then lets go and kick crocodile's ass."
Said Zack while walking towards the kitchen in which monnet and Robin made food for them.
Next chapter will be end of arabasta arc and they will directly go towards new world to meet big shots.
I don't like fight scenes in novels so i also made it as simple as i could.
