That was because Haku had already captured King's figure within his Observation Haki.
He knew clearly that the other man was charging straight toward this battlefield, and without a doubt, if Haku did not finish the battle quickly,
what would greet him next was the joint attack of a powerhouse at the level of the Four Emperors and a powerhouse at the quasi-Four Emperors level.
Although Haku was confident in his current strength to make a complete and safe retreat,
there was a huge possibility that he would face the risk of the system judging his mission as a failure.
Once the mission failed, it meant his strength could not be further improved!
This kind of consequence was simply not something he could accept in his heart!
"Blade Twin Emperors!"
The unknown flames on King's body suddenly erupted, and he flapped his wings rapidly, launching fire bullets from the flames on his back.
The flying quantity and speed were just like being fired from a machine gun!
Haku utilized Shunpo, his figure continuously flashing among the fire bullets.
Along with each disappearance and reappearance, Haku's body grew closer and closer to King's direction!
"Fuzhan!"
The spiritual pressure gathered on the blade's edge was released at extreme speed along with Haku's slash!
King raised the giant samurai sword in his hand, coated it with Armament Haki, and blocked forward.
The fire caused by the attacks of the two instantly ignited the entire Jinbu Port!
Haku, holding Ryujin Jakka, instantly fought King to a standstill!
The hand-to-hand combat ability bestowed upon him by the system finally revealed its edge in this battle!
"Damn it, how can this bastard's swordsmanship be so strong!"
A wave of irritation surged in King's heart, as he simply could not understand how Haku possessed such powerful swordsmanship.
Unfortunately, what Haku possessed was not just simple swordsmanship; his body rapidly underwent elementalization. Relying on the ultimate speed brought by the Rumble-Rumble Fruit, he appeared behind King!
Ghost Fire!
Haku held Ryujin Jakka and thrust forward, the spiritual pressure borne on its tip capable of instantly piercing through King the moment it touched the opponent's body.
Feeling the threat from behind, King knew it was already too late to turn around and block!
He instantly spread his wings and swept forward, barely dodging Haku's extremely dangerous attack!
Haku felt a trace of regret in his heart for the missed move. There was no help for it; he knew that those whose strength reached the quasi-Emperor tier had already applied their Observation Haki to perfection!
Haku himself was not the kind of assassin who could conceal his own aura, so he naturally could not escape the other's lock-on!
At this moment, King had already hovered in mid-air with the help of his flight ability!
How could Haku, whose own strength was in the upper hand, let the opponent off so easily? Thus, he stepped on Geppo and chased after King in mid-air!
King's gaze narrowed; Haku was not someone who could move freely in the air like him!
Now the opponent actually dared to chase him into the air! To him, this was simply a living target!
"Diao Zi Zun Huang!"
King suddenly pulled his head back like a slingshot, then released it to generate a powerful shockwave shot toward Haku!
A trace of red light flashed in Haku's eyes, and within his Observation Haki, he seemed to see something!
"Binding Arts Eighty-One, Broken Sky!"
An invisible barrier emerged in front of Haku!
The moment the barrier formed, it was immediately shattered directly by King's attack!
Haku raised the Zanpakuto in his hand, coating the blade with Armament Haki to neutralize the remaining attack power!
However, after this blow, Haku's body was finally knocked back down to the ground.
He opened his mouth and taunted King: "What? Too scared to return to the ground? A grand quasi-Emperor is afraid?"
King's face beneath his mask did not change because of Haku's taunt: "You think this kind of aggressive provocation can work on me? I ate the Zoan: Dragon-Dragon Fruit, Ancient Species, Pteranodon!"
"Above the sky, I am the king!"
"Diao Zi Zun Huang!"
King used the exact same move again. Facing such a nearly shameless and powerful move, Haku could only step on Shunpo to leave the spot!
Haku changed his position and gazed coldly into the air!
"Making it seem like you're the only one with Devil Fruit abilities! Since you like staying in the sky so much, then taste the power of the Rumble-Rumble Fruit!"
As soon as Haku finished speaking, electric arcs flickered around his body, and the sky, which had already been affected by Haku's ability, began to rumble with thunder and flash with lightning!
"Ninety Million Volts, Thunder Beast!"
Haku raised Ryujin Jakka high in his hand, and the voltage at the tip of the blade was suddenly released. An electric arc burst directly from the blade in Haku's hand!
Then it formed a beast transformed from lightning!
Under Haku's control, this Thunder Beast rushed toward King in the air at extreme speed!
"Damn it, how is this possible!"
King's pupils suddenly shrank, and until now he suddenly remembered that the opponent could also use powerful lightning abilities!
This couldn't really be blamed on King for constantly ignoring Haku's Rumble ability; it was mainly because Haku wasn't yet used to combining the Rumble-Rumble Fruit's abilities for combat!
And feeling the power contained in this lightning-transformed beast, even he probably couldn't withstand it!
At this moment, while dodging the opponent's attack, King had to fly at extreme speed in mid-air!
As a result, he was in a quite passive position!
If the opponent had no lightning ability, King could attack him recklessly, but now that the opponent possessed this ability, he didn't dare to attack easily!
"Boom!"
The Thunder Beast collided with King, and the powerful explosion instantly resounded through the entire Jinbu Port!
At this moment, King's body plummeted at extreme speed like a broken arrow!
A wave of annoyance rose in his heart, never expecting that he would be forced to this point by the opponent!
"Damn bastard!"
King roared angrily in his heart, raising the samurai sword in his hand, gathering all his strength to slash toward the ground!
"Super Guardian Fire Dragon Emperor!"
King hurled out another giant flame dragon!
"One Hundred Million Volts, Thunder Dragon!"
Haku also showed no weakness, hurling out a thunder dragon to fight it!
"Boom!"
The two collided to produce an even more violent explosion!
Using the cover of the smoke and dust generated by the explosion, King transformed back into his Pteranodon form and sprinted toward the spot where Haku stood!
It looked like he intended to rely on his beak to smash into Haku's body!
Haku, who had kept Observation Haki active, naturally saw this scene!
"Binding Arts Thirty-Seven, Hanging Star"
Haku used spiritual power to create an oversized giant net in front of him, easily and successfully stopping King's head-on charging momentum!
"Hehehe!"
A cruel smile appeared at the corner of Haku's mouth!
After being trapped by the Hanging Star, King's body struggled for a moment without being able to break free!
"One Hundred and Fifty Million Volts, Heavenly Punishment Descends!"
In the sky, thunder that had been gathering for a long time directly transformed into a thick pillar of lightning and struck the location where King was!
"Oh no!"
Looking at this destructive attack, King felt a sudden sense of dread in his heart.
With no time to think further, he could only follow his instinct to spread the wings on his back and wrap them around his body!
