One Piece: True Several Thousand Hands, rampaging across Marineford!

Billy believed that this sword strike was extremely energy-consuming; regardless of whether it was actually used, simply gathering a large amount of energy would consume a great deal of mental energy.

"Kahn!"

Despite suffering a loss, Steelbone's aura intensified, his muscles contracted, and his blood slowly congealed. He roared, "You're not leaving! I haven't been completely defeated! I haven't lost to you!"

"Hahaha!"

Kahn laughed loudly, "You've already lost the moment you said that."

"Pfft~!"

Steel Bones coughed up a mouthful of blood, and the injuries he had just suppressed continued to bleed.

"I can't let you leave so easily."

Billy let out a long sigh of relief.

Logia-type Swamp-Swamp Fruit Awakening Activated!!

The sky, the ground, the sea... it's all swamp. Swamps cover this space, turning everything that can be transformed into swamps.

"The fruit awakens."

Kahn was not surprised.

The Commander-in-Chief of the Three Armies is a Devil Fruit user who has eaten a Devil Fruit, but he hasn't even awakened his Devil Fruit power yet, so he's not qualified to be one of the top figures in the sea.

"Little guy."

Billy said, "You should stay here and let Kong give you a good beating."

He got a beating from Steel Bone.

Perhaps then Steel Bones' beliefs and spirit will remain unaffected.

He had a "nothing to lose" mentality.

Kahn didn't want to stay here.

Having achieved our objectives, staying here would be unwise.

His trump card has been tested by Steel Bone Kong with his body, making it difficult to achieve such good results again. For example, the blow that struck the Hive Sea like a cataclysmic event was known to the entire ocean.

No longer a trump card.

This move, which consumes a great deal of mental energy and is concentrated in the sword, is no longer a trump card.

this day.

Kahn gathered his strength more than a dozen times, expending unimaginable mental energy, before he finally managed to get Cyborg to take the hit head-on.

He defeated Steel Bone Sky in one move.

To create an unprecedented miracle.

He felt a little dizzy. Although he had a strong will, it didn't mean he had no limits.

Every breakthrough in willpower has its limits.

A typical top-tier expert could only gather this technique a few times and unleash it a few times.

Kahn could gather dozens, even hundreds of times.

After gathering.

If you believe you can't defeat your opponent, you don't need to unleash your power, saving half of your mental energy.

"..."

Faced with Billy's awakened Devil Fruit, Kahn activated his own Devil Fruit ability, attempting to use the life elements he created to spatially transform and teleport away.

He failed, as if there was a wall, a wall imbued with life, blocking his way.

This swamp is strange.

So be it.

This commander-in-chief, who did not appear in the original work, piqued Kahn's interest. He wanted to test the waters and see how he handled things, so as to make some preparations for the great war to come.

Countless arms formed from swamps sealed off Kahn's space layer by layer, making their attack angles exceptionally tricky.

Bang!

Bang!

Bang!

Each arm attacks Kahn from various angles, forming a ball.

But Billy looked grim.

Ran!

We couldn't catch it; there was no sign of human life inside.

"Where is it?"

Billy thought to himself, "There's no way I can escape. My awakened Devil Fruit ability has sealed off the entire sky and sea. I can't break through using my special Devil Fruit ability. If I were to attack directly, I would definitely be able to sense it."

call out!

Kahn appeared above Billy, wielding a dragon's roar, and slashed at Billy.

"They didn't run away; they chose to come back and deal with this old man, you daring young man."

Billy's body transformed into a swamp, and a hand covered in Armament Haki appeared.

It stretched out.

Block this attack.

"Advanced Observation Haki".

Kahn laughed and said, "It seems that with his age and many years of life, his domineering aura is very strong no matter what."

"Not as good as you."

Billy shook his head. The ability to teleport is not something everyone has. Moreover, if the space cannot be restricted, teleportation is very difficult to deal with, especially with this young man's powerful attack.

He's simply the most terrifying assassin.

If one's Observation Haki is even slightly lacking, or if one's physical reaction is too slow, one can be taken out in one combo.

Billy also heard that this young man was immortal, his physical body was almost impossible to kill, and the only way to kill him was to exhaust his mental energy to the limit, putting him into a deep sleep, or to have a group of powerful people gang up on him and capture him alive.

He can be described as the most terrifying top-tier powerhouse on the high seas.

Kahn continued his battle with Billy.

After recovering from his serious injuries, Steelbone attacked Kahn, determined to avenge his defeat.

This time, both Billy and Steelbone Sky have become incredibly cunning.

As soon as danger is sensed.

Both of them left Cain, and Billy used his Devil Fruit ability to restrain him.

There is no danger.

The two of them went together.

"Naval Headquarters, the World Government's foundation is truly formidable."

As Kahn fought, he thought to himself, "No wonder no one can change this world. Pirates from every era can't even beat the Marine Headquarters, let alone deal with the World Government."

Kahn was in a relaxed state of mind.

This was the most relaxed he had been in recent days, and he played better and better.

It's because all the missions in Impel Down have been completed.

My only task now is to measure the specific combat strength of the commander-in-chief and whether the opponent has any hidden Devil Fruit abilities or methods. Although the commander-in-chief Billy's awakened Devil Fruit ability is already terrifying, it may not be all the methods he has.

Half a day later.

"Steel Bones Crushed!"

Steel Bone Sky unleashed a furious punch, distorting the very fabric of space.

"roll!"

Kahn unleashed a full-force attack, slashing at Steelbone.

boom!!!

Steel Bone was knocked back, and his wounds became uncontrollable again, with blood gushing out.

"Damn it!"

Steelbone Kong angrily retorted, "If it weren't for that sword strike, with your strength alone, you wouldn't be able to defeat me in a head-on confrontation!"

"hehe."

Kahn retorted with a laugh, "That sword strike was also a testament to my skill."

"..."

Steel Bones was speechless.

He can only pay the price for his carelessness.

He was severely injured and could unleash his full power for a brief moment, but that momentary power was only 80% of his normal strength.

The burst of power in the normal state of the steel skeleton.

It's going to be even more amazing.

"Caught!"

Billy yelled, clenching his fist, "Don't even think about running away!"

This time, Billy's Devil Fruit ability successfully caught up with Cain, who had just repelled Kong. He immediately transformed into an element, becoming a swamp, and plunged into a large swampy area, enveloping his opponent and extending his two hands.

Two hands wrapped in Armament Haki.

They grabbed Kahn, who was temporarily trapped.

"We've got him."
