The Plan

Looking at Whitebeard who becomes a walking killing machine, Xin first needs to wake him before he really razes the whole Marineford into the sea.

Whitebeard punched out using his tremor ability on Xin's stomach but Xin calmly recessive it, with the weird vibration that he felt, Xin, felt that the strongest devil fruit is not that strong at all.

He kicked Whitebeard to his head and then combo him using three consecutive kicks, after that, he used a drop kick making Whitebeard's huge body pummel down to the ground.

Boom!

"Pop!"

Marco tries to help Whitebeard but Xin appears in front of him to stop his action.

"Don't come, Whitebeard is unconscious right now, if you come closer, you will accidentally attack by him"

"I can help to heal Pops, I can use my flame."

"You can't, your devil fruit can be used to heal but not to wake up someone," Xin then pushed him away and raised his hand blocking Whitebeard's gigantic legs.

Tori Tori no Mi, Model: Phoenix

The Tori Tori no Mi, Model: Phoenix is a Mythical Zoan-type Devil Fruit that bestows the power to transform into a phoenix at will. It was eaten by Marco.

This Devil Fruit grants the power to transform into a large phoenix shrouded in blue flames, as well as a human-phoenix hybrid at will.

Instead of burning, the phoenix flames have immense healing properties. By cloaking themselves in the flames, the user can rapidly regenerate from all injuries inflicted onto them, lethal included, much like how a phoenix is said to rise from its own ashes.

Thus, the user boasts enormous resilience, able to undergo extreme punishment without so much as feeling pain or being slowed down. In Marco's case, injuries like his body being perforated all over, having his head run through, or parts of his head and neck blown off have elicited little reaction from him, the wounds simply disappearing in the flames almost as quickly as they were made.

On top of self-healing, the phoenix flames may be applied to other living targets in order to mend them, but in that capacity to heal others, the flames have a smaller effect. Once the flames have lit other people, they stay with and continuously heal them.

But as Xin said, healing is for the wounded one not for the unconscious, and the unconscious is not a sickness whatsoever but a debuffing state.

Boom!

Xin's body did not move at all but the impact on the other side of his body is devastating, even Marco throws like a sandbag by the impact of the kick.

Xin then pushes his feet, then kicks him away from the other thwn dash chasing Whitebeard while unleashing a set of combo kicks to try to wake him up.

When he was about to kick again, Whitebeard suddenly grabbed his feet and grinned towards him, stopping his body from being thrown.

"Are you going to help me to massage my head using your skinny feet? Gu ra ra ra ra ra~" Whitebeard laughed unbridledly..

"So you finally woke up and slept?"

"That's to your message i finally awake, let me give you my thanks for waking me up," Whitebeard then throws Xin in the middle of the plaza hitting Marien and Pirates.

He then prepared his stance holding his Naginata, with one push his arm turned darker with the Naginata and a bubble started to condense on the tip of it.

"Kid! Try to recess my attack!"

"Run!" Someone suddenly shot in fear making them discover that they are all the range of Whitebeard's attack, but it's too late, Whitebeard already slash horizontally.

Xin jumps out from the ground and kicks his weapon using his leg coated with golden Haki making the attack change direction.

He was about to land when Whitebeard actually arrived near him grabbing his head and pushing it on the ground.

With tremor ability, he tries to shake Xin's head and push it down but Xin grabs his hand while raising his head while one of his feet is stepping on Whitebeard's head.

"Kid, you are the first one who ever stepped on my face, Roger cant even do that."

"Then Roger is too weak, I can step on your face easily."

"Well, Roger is really weak," he then raise Xin and is about to throw again but Xin's is faster than him, he hooks his leg around his neck escaping from his clutch then pull him back ward and perform a german suplex imbedding Whitebeard's huge head in the ground.

Xin who is about to jump away to rake distance recessive a kick from Marco who tries to save Whitebeard.

"Pops!"

Whitebeard pushed his arm upward, removing his head from the floor. He started to move his head and said," Don't worry, I just want to fight his kid before we save Ace, I want to check what kind of enemy you guys will face in the future."

"-Pops….. We can still go back…. You can just let us save Ace.."

"No need Marco, I know my condition more than the doctor on our ship and you…. My time is running out….. My last wish is to die while fighting and not while lying around…"

"....."

"It seems you forgot us, Whitebeard." Akaino then kicks him from behind but Whitebeard blocks his kick with one swipe of his weapon.

"Do you think we need help from a kid to take you down?"

"Durarara~ if not?"

Whitebeard and Akainu punch at the same time, a gigantic molten magma fist and tremor punch hit each other creating a huge explosion around.

Magma starts to fly everywhere, the house around starts to burn while Aokiji becomes a fireman helping everyone to put out the fire or else even if they save the Marineford from Whitebeard, they will only leave with burning ground by Akaino's ability.

Whitebeard and Akaino start exchanging punches not even bothering what kind of damage they create while Xin sits back again near Ace.

"Ace, get ready."

"What do you mean?"

"I will let you escape, bring your friends back, don't look back, don't try to save Whitebeard."

"No! I can't do that! I can't leave Pops.``

"Ace….. Whitebeard is dying right now…. His life force is almost exhausted… any moment he is about to fall…"

"...." Ace
