New Emperor

"Well well what a grand reception! i am flattered."

Zack said while smiling towards Big mom whose ugly face was looking more ugly due to anger.

"Ma Ma~ You damn brat, you sure are one brave fool to come to my territory to challenge me."

Big mom said while laughing in anger.

"Oh no no i didn't come here to challenge you." said jack.

"if you are not here to challenge me then why are you here?" asked Big mom while being a little bit confused.

"I am not here to challenge you, i am here to destroy you." Zack said in a matter of fact tune.

"MAMAMAMMAMA~ you are here to destroy me? Ok now i am really angry. Children ATTACK!" Big mom suddenly burst with anger and ordered her children to attack.

"OOH!" suddenly each of Big mom commanders as well as other pirates attacked heavenly pirates.

"Guys TOTAL ANNIHILATION! " Zack also ordered Heavenly prates to attack and he himself directly shot towards big mom while his fist turned dark with armament haki. Seeing Zack rush towards her big mom's fist also turned black and she sent her fist towards Zack.

"BOOM!!" when both there fists collided it created a very huge shock wave which interrupted some of the fights happening nearby, at the same time both Big mom as well as Zack unleashed their conqueror's haki but it at once became clear that big mom was on the losing end as Zack can easily see some sweat on the face of big mom.

'As i thought big mom's conqueror's haki is the weakest haki among-st all the emperors.' Zack thought inside his head.

"Haha you really are the weakest amongst all the current emperors." Zack said to Big mom.

"Damn Brat! you are courting death, come here Nepoleon." Big Mom became angry when she heard Zack calling her the weakest emperor, and directly started using her devil fruit's ability to make her hat into a sword and directly slashed towards Zack.

But on the other hand Zack just coated his hands and started to fight her using bare handed martial arts.

As their fight was getting intense, the other heavenly pirates were also bringing hell upon Big mom's pirates. They were too strong due to their training which was personally handled by Hang Wei who was the creator of one piece world.

On the other hand Big mom pirates including the commanders were getting slain by the hands of heavenly pirates.

And all the devil fruits were being collected with Hang Wei, due to the barrier which he erected over the whole cake island before the fight began. And all the dead bodies were being turned into undead due to the influence of heavenly world, controled by Eve. And after turning into undead they also started attacking Big mom's pirates.

After fighting for more than an hour Zack started to get bored because all of Big mom's fighting patterns were clearly understood by him and there was no longer any thrill in that fight, so Zack also started to use his devil fruit.

"Black Hole!!" Zack shouted and tapped his foot on the ground and pitch black darkness started to move towards Big Mom, who seeing this began to feel fear, and tried to jump away from that darkness but some black tendrils shot out from ground and tightly held Big Mom in her place. After which she was devoured by black hole.

When she was devoured by darkness then Zack directly put his hand into the void and said "Memory tempering!" and after some time Zack recalled all his power back and with a thud Big mom was thrown on the ground.

A little while later big mom stirred awake and when she saw Zack standing near her she directly knelt in front of him and said " Master! Charlot linlin at your service." with utmost loyalty.

Yes some time ago Zack found out about another hidden ability of his perfect darkness fruit which is to temper with the memory of people and right now he used the same ability to change Big mom's memories and made her his loyal slave.

"Hm good stand to the side." Zack told her to stand to the side because now she was blocking his view.

"As you wish master." she said and stood to the side and also watched the massacre of big mom's pirates. But there was no change in her expression.

After some time no one was left alive from Big mom pirates and all of them were turned into undead.

"Very good! Now as it was planned you just teleport to your ships which are now stationed near the territories of Big mom and take every thing which belonged to Big Mom's pirates under our wing." Zack then ordered his commanders when they assembled in front of Zack.

"Young Master! there are marine battleships encircling the whole cake island. I think that they planned to attack us when we are at our weakest after our fight." Hang wei came and told Zack.

"HM!!! well continue with the plan and take over the territories, and as for those marines i will disperse them. Now is not the time to destroy them." Zack told them to carry out the assimilation of territories. It is not that he couldn't destroy them now but if he did that it will hinder his plans for future.

"Young master do you want me to take out those battle ships?" asked Hang wei.

"No i will deal with them now. Summoning Jutsu!" Zack declined Hang wei's offer and then made some hand seals and put his hand on ground.

'BOOM' with a bang sound a cloud of smoke appeared in their vicinity. When the smoke dispersed a very big beast apeared which resembled a large turtle, but with a crab-like shell, it had spikes all over its body, and three shrimp-like tails. Under its shell, it had red, muscle-like tissue. It had a pair of human-like arms and hands, but no hind-legs. His face was concealed between a large forehead and lower jaw — both of which had spikes. Its eyes were red and had crimson pupils.

Its right eye was constantly closed.

"ROAR!!" as soon as that beast appeared it roared and a very powerful aura was released from it.

"Master why did you summon me? Do you need my assistance?" that beast asked Zack who was now standing on its head.

"Yes Isobu i have a task for you. There are some pests surrounding this island i want you to get rid of them but keep the casualities as minimum as possible." Zack ordered isobu while smiling.

"Of course master just watch." saying this Isobu turned towards the coast while Zack jumped away from Isobu's head and landes between dumbfounded Heavenly pirates.

"Haha now just watch the show." Zack told the others, and then they shifted their attention towards Isobu who had entered the water moving towards that side which was lead by Akainu.

--------------------------------------------------

Meanwhile the marines were waiting for the signal to attack. As before the island was covered by some sort of barrier they were not able to see what was happening inside. But some time ago the barrier disappeared but there was total silence on the island as if there was nothing happpening.

As the admirals were debating to attack or not, the surrounding area of the island started to get covered in some sort of mist which made their vision severely restricted.

Akainu wanted to attack the island but that mist delayed his plans. He became very angry. As he was about to order his subordinates to advance, his face suddenly changed and he atonce used geppo and jumped in the air. The moment he jumped in the air he heard a loud "BANG" sound and saw a cloud of smoke rising from his previous place.

What he saw made him drenched in cold sweat because four of the battleships under his command had totally vanished and two of his vice admirals also turned to ash, while other two vice admirals were quick to use geppo which saved their lives.

These three people glanced at one another and atonce retreated. They wanted to get away from this mist as fast as possible.

Aokiji and Kizaru also heard the loud sound and they atonce contacted with one another but they also became totally dumbfounded when they were not able to get in contact with Akainue's troops.

They atonce converged with one another and ordered to retreat.

After some time they retreated a fair amount of distance away from the mist. When they got out of the misty area they saw three people hovering in the air and were astonished to find out that they were precisely Akainu and two other vice admirals who were in Akainu's fleet.

Akainu also saw them and moved onto that ship where both Aokiji and Kizaru were waiting.

When he landed on that ship Aokiji atonce asked him that

"Akainu, What happened? Where is your fleet?"

When Akainu heard him his face turned very bitter and told them that what happened.

"I don't know. When this damned mist covered us i was about to advance to whole cake island that i sensed danger due to observation haki and atonce jumped into the air. After that we heard a loud sound and when the mist dispersed due to the explosion our fleet just vanished."

"Hm~ it looks like we underestimated the severity of this matter. I don't know what is happening on that island but one thing is for sure, the world is going to stir." Kizaru said in his laid back voice.

"True. But now our mission is total failure. Lets go back to headquarter and give our report to fleet admiral and wait for the news of whole cake island." Aokiji said and ordered the fleet to head towards the headquarter.

The morale of the whole fleet was at the most bottom due to the loss of their four battleships including the marines stationed on them as well as the two vice admirals who vanished in that attack. And on top of all this they didn't even know what hit them or what was happening on whole cake island.

--------------------------------------------------

"Wow boss! this beast is amazing. He totally destroyed four battleships with one attack and made the marines run with their tail between their legs." Jewelry bonny said while eating one big piece of meat.

"Yes he is amazing. Now all of you go and fulfill your orders. I want all of bigmom's territories under control before dawn. Now go!" Zack told the heavenly pirates who then activated teleportation seals on their hands and teleported to their ships which were stationed near the different territorie of Big Mom's before the fight began on the orders of Zack.

--------------------------------------------------

When dawn came it brought a tsunami in the world, due to the changes which were caused by the power shifting which happened in the span of one night.

And the appearance of one powerful younku who emerged in one night whose name resounded in the world.

"Zack The Heavenly Yonku."
