Akainu was slowly recovering, Aokiji was held back by Jozu, Kizaru was occupied by Marco, and Whitebeard, being elderly, could not break through the encirclement of the marines for the moment.
Meanwhile, Ace, using the chaos of the battle, had descended to the battlefield below, only to be intercepted by five Vice Admirals, one of whom was Momonga.
Sengoku, fully aware of Luffy's identity, directly announced via Den Den Mushi that Luffy was the son of Monkey D. Dragon, the leader of the Revolutionary Army.
The Whitebeard Pirates also learned that Luffy was Ace's brother, prompting various division commanders to rush to Luffy's aid to help him break through.
However, most of them were no match for Mihawk. It wasn't until Flower Blade Vista intervened, stopping Mihawk, that Luffy was able to escape. But then Luffy was blocked by Moria, only to be assisted by Jinbe.
On Li Xing's side, after dealing with Garp, he slowly walked towards Luffy. Suddenly, a cloud of smoke appeared, and Smoker blocked Li Xing's path.
"This is Marine Headquarters! I will absolutely not let you run rampant!"
Li Xing shook his head and said, "Even if this were Mary Geoise, I could still do as I please. Do you think you can stop me?"
They had little common ground. Smoker immediately enveloped Li Xing in smoke, then soared into the sky before diving rapidly, wielding his Seastone-tipped Jitte.
"Come to think of it, I haven't tried Armament Haki yet." As soon as he spoke, Li Xing threw a punch. Even through the air, he could hit Smoker with Armament Haki. Of course, it was invisible. Smoker was knocked unconscious by the punch.
"Advanced Armament Haki, never seen it before, have you?"
Just as Li Xing was about to leave, Tashigi leaped into the air with a sword, attacking him. Li Xing swung one hand, and just as he was about to collide with Tashigi, a Nichirin Blade appeared in his hand. A slash sent Tashigi flying.
"You're still too far from wielding a sword against me!"
Then Li Xing appeared before Luffy, holding his sword horizontally at Luffy's chest. Luffy dodged by bending over.
"Li Xing, what are you doing? Aren't we allies?"
"Who said I was with you? I'm here to make you grow. Your current strength is too weak. I'll teach you what combat is!"
With that, Li Xing swung his sword. But at that moment, Crocodile lunged in front of Luffy, blocking Li Xing's attack.
"Bastard! I haven't settled the score from last time!" Crocodile's face was grim, as if he were going to devour Li Xing.
"Another one? You're just a defeated opponent. What can you do?"
"Desert Storm!"
Crocodile didn't want to waste words with Li Xing. He unleashed a sandstorm with one hand, blowing Li Xing into the sky. Li Xing chuckled in mid-air, his Nichirin Blade transforming into a long, red bow.
"Blood Demon Art! Heart Piercer!"
Li Xing drew the long bow to its fullest and shot a red flash, aiming at Luffy. Luffy suddenly saw a vision of himself being impaled and dying. He stopped in his tracks, causing Li Xing's arrow to miss.
"You damn guy! Are you looking down on me!"
Crocodile was furious. Li Xing was fighting him yet still intended to attack someone else, completely ignoring him. It was truly detestable.
Just as Li Xing was preparing to shoot a second arrow, Whitebeard punched forcefully, knocking Li Xing from the sky.
Mihawk also understood. Without Luffy saying a word, many people were willing to help him. Luffy possessed the most terrifying power on this sea. His objective of measuring Luffy had been achieved. Mihawk immediately stopped his actions and moved aside.
Li Xing, however, now had his sights set on Mihawk. He wanted to test the skill of the world's greatest swordsman. His long bow transformed back into a sword. Li Xing instantly appeared beside Mihawk, forcing him to engage in combat.
He didn't know until they fought that Mihawk felt immense pressure. Li Xing's swordsmanship was simple, yet every strike was sharp and ruthless, no weaker than his own. When did such a powerful swordsman appear on the sea?
...
On the other side, Luffy had reached Ace's side. The two brothers broke through the encirclement of the Vice Admirals together. Ace was rescued, and Whitebeard gave the order to retreat.
But Sengoku was not to be trifled with. He unleashed a shockwave palm strike. Whitebeard returned a punch, and the collision of their powers sent many weaker individuals flying.
Kizaru and Aokiji had also defeated Marco and Jozu. As they were about to advance, Ivankov winked, forcing the two Admirals back. Kizaru, being the fastest, tried to turn into light and fly over, but was repeatedly interrupted by Ivankov's winks.
However, at this moment, Akainu finally recovered. Seeing the pirates about to retreat, Akainu uttered some taunts and insults towards Whitebeard. This enraged Ace, and he immediately turned back to fight Akainu.
But Ace was no match for Akainu. Ace's flames were extinguished upon contact with magma. He was completely outmatched.
Luffy, due to the residual power of their fight, accidentally dropped Ace's Vivre Card. As Luffy tried to pick it up, Akainu launched a punch.
At the critical moment, Ace shielded Luffy with his body. While he protected Luffy, his chest was pierced by Akainu, and his Vivre Card began to dissipate.
Seeing Ace take the hit for him, Luffy hugged Ace's body, only to feel scalding blood. Just as Akainu was about to finish them off, Whitebeard appeared behind Akainu and sent him flying with an enraged punch.
As Ace finally died, Luffy wailed in grief, losing consciousness almost instantly. Clearly, Luffy could not accept Ace's death.
Seeing this, Li Xing lost the urge to continue fighting Mihawk. With a casual sword strike, he sent Mihawk flying, "We'll fight another time. I've lost interest."
Mihawk, being proud, would not challenge a newcomer in front of so many people. He sheathed his sword and stood aside.
"Alas, my old bones can't bear to watch such things!"
Li Xing's heart softened after all. He secretly hid Ace's body in the initial sphere space and set up the Edo Tensei jutsu. The ritual would activate in ten years. In ten years, Luffy should also become king, which was enough.
The brotherly bond between Ace and Luffy, as well as the familial ties between Ace and Whitebeard, touched Li Xing. Family was also what Li Xing cherished most. He couldn't bring himself to be ruthless and chose to have Ace resurrected later.
"Sage Art! Wood Style! Deep Forest Emergence!"
Li Xing once again used Wood Style. This time, Li Xing exerted a tenth of his strength, binding almost everyone in Marineford in an instant. Those touched by Wood Style had their spiritual power absorbed, and they all became sluggish, wanting to sleep like pigs.
"The war is over! Let's not waste time. Lan Pang Zi, take Luffy and go!"
Jinbe, who had been holding back Aokiji, finally had free time. Without a word, he prepared to take Luffy away. However, at this moment, a dark light flashed, and Blackbeard arrived at Marineford with a group of people.
"Kid over there, let me go. I need to settle this." Whitebeard looked at Li Xing and said.
Li Xing released Whitebeard, allowing him to deal with Blackbeard himself. However, Li Xing knew very well that Whitebeard would die.
...
As expected, Whitebeard's abilities were ineffective against Blackbeard's. In the end, he fought Blackbeard with physical combat, but ultimately showed mercy and was ambushed by Blackbeard, dying on the battlefield while standing.
The Whitebeard Pirates wailed "Pops!" in grief, but Li Xing threw them all onto the ship. The marines were thrown back onto land by Li Xing.
Blackbeard, upon Whitebeard's death, finally laughed heartily. He then covered himself with a black cloth. When he reappeared, Blackbeard unleashed a punch that destroyed the entire Marineford.
Blackbeard intended to continue punching, but Li Xing exhaled, melting the ice beneath his feet. Blackbeard and his crew instantly sank into the sea. Fortunately, not all of them were Devil Fruit users, or Blackbeard would have drowned.
"I said it's over. Don't you understand human language? Or do you want to fight me?"
After being pulled to the surface, Blackbeard looked at Li Xing as if he were being stared at by a ferocious beast. He had no choice but to leave with his subordinates.
Finally, the Red-Haired Pirates, one of the Four Emperors, arrived at Marineford. Shanks' intention was to end the war, but it was too late. In the end, with Shanks' influence, he obtained the right to bury the bodies of Whitebeard and Ace. However, Ace's body was not found. He then took Whitebeard's body and left.
Finally, Li Xing withdrew the Wood Style, and the trees growing from the seabed instantly disappeared. Li Xing then pursued in the direction Jinbe had left.
Catching up with Jinbe, Li Xing asked him to take Luffy with him back to Amazon Lily. Jinbe was hesitant to trust Li Xing, but since Li Xing was the one asking him to take Luffy away, he had no choice but to follow Li Xing to Amazon Lily.
Li Xing flew into the sky, carrying two people, and quickly headed towards Amazon Lily. Along the way, he encountered Law's Heart Pirates. Li Xing informed them that the war was over and told Law to hurry back to sleep. Then he flew away without looking back.
