One Piece: The Magician

Sherlock's current limit is six-fold mirror fusion, and this was barely achieved after overdrafting Insomona's energy.

But the terrifying destructive power, just the aftermath of the confrontation with Blackbeard, was able to destroy most of Mogu Town.

With each additional level of mirror image fusion, its power is doubled exponentially, and at the same time, the amount of mental energy consumed is also increasing.

Sherlock couldn't imagine how powerful a person with abilities was to be able to use the nine-fold mirror fusion and allow it to exist forever.

Could it be because of the fusion of devil fruits?

Wait, it seems that besides the psychic power of the esper, there is another way to maintain mirror fusion for a long time.

An astonishing thought flashed through Sherlock's mind. With a thought in his mind, accompanied by a scarlet light, a spear full of destructive aura appeared out of thin air in front of the sorcerer.

The god-killing spear Gungnir.

Sherlock reached out and gently touched the cold body of the God's Killing Gun, his eyes gradually becoming weird.

The magician used this spear captured from the small garden to defeat powerful enemies several times, but at this moment, a certain glasses suddenly felt that this spear was so unfamiliar.

Why is there always a strange sense of dissonance every time I use mirror fusion on this god-killing gun?

Why is the God Killing Gun so much more powerful than other mirror image fusions?

Why does the six-fold fused divine killing gun awaken its thunder attribute and turn into a blood-colored thunder gun made purely of lightning?

Why can this gun absorb lightning and increase its own power?

Now, Sherlock finally got the answer:

The essence of the God Killing Gun is also an eternal mirror fusion.

The exact number of levels of mirror fusion is unknown, but it definitely exceeds the sixth level. However, due to the passage of time, its original terrifying energy has long been exhausted, otherwise it would not have been hidden from Sherlock's perception.

It's also fused with a Devil Fruit, and its abilities are definitely related to lightning.

"What's wrong Sherlock?"

Looking at the abnormal behavior of a certain glasses, Robin couldn't help asking: "What are you doing with this spear?"

"It's okay, I just suddenly figured out a few questions."

Sherlock came back to his senses, waved away the God Killing Spear, and continued to admire the murals.

The next few murals depict scenes of the prince holding the Seven-Star Holy Sword and leading the army to fight everywhere.

There are many enemies that the prince fights with.

There is a warrior whose body is covered with static electricity and whose body features resemble those of a furry animal.Under the full moon, those pairs of scarlet eyes are full of the most primitive wildness and ferocity of animals.

There are samurai with Tsukiyo haircuts and haori. Each of them has superb swordsmanship. The long sword in their hand seems to be able to kill all enemies in the world.

There are demonic troops that are as big as mountains and have sharp fangs that look like devils. Compared with these real giants, the two giants in the small garden are like children.

There is a legion of dragon knights riding huge flying dragon mounts on their crotches, flying freely in the sky. The pure white knight armor has no trace of color, and the dragon wings cover the sky and the sun.

There are fish-men who lead countless giant sea kings, those overlords from the deep sea. Even the smallest one has a terrifying size comparable to that of an island.

and also

Thousands of years ago, they were probably the most powerful combatants in the world.

But in the face of the terrifying power of the Seven Star Sword that transcends the shackles of the world, all resistance seems to be in vain.

Human dragon or Neptune?

No matter what kind of enemy he faces, there is only one thing the prince does

The sword comes out, the black flame rises, and all living beings surrender

"What a terrifying power. Why is this sword so powerful?"

Robin murmured to himself, his beautiful blue and black eyes filled with unconcealable shock.

Combined with the information he had previously obtained from the Burial Hall in Alabasta, in terms of its destructive power against the army, the Seven Star Sword was probably not far behind the legendary ancient weapon Pluto.

This talented archaeologist has been well-read since she was a child, and she can identify almost all the enemies depicted in the murals fighting against the prince.

"The top beings among the giants, the demons, the samurai of Wano Country, and the fur tribe warriors of Zou Island, it is said that they will fall into a state of madness under the full moon."

"Grant's Dragon Knights, the Nation of Knights, seems to be in

Thousands of years ago, the creature dragon did exist. "

"And those giant sea kings"

Recalling the historical text he read under the huge golden bell tower, Robin reached out and rubbed his smooth and round chin, thinking quietly.

These murals were created thousands of years ago, even long before the "800 years of blankness" 100 years ago.

This means that the ancient weapon may have existed a long time ago on Fish-Man Island.

Robin's eyes lit up instantly, and her face, which had always been cold and indifferent, showed joy from the bottom of her heart.

For an archaeologist like her who is passionate about archaeology, there is nothing more pleasurable than exploring real history to reveal the truth about the world.

After fierce battles with all forces, the content on the mural changed again.

This is a void and vast space. The prince is waving the seven-star sword in his hand and is fighting an incarnation that is almost identical to himself.

The only difference between the Avatar and the Prince is that his eyes are the same eerie crimson as the Eyes of Azathoth.

After all the hard work, the prince finally defeated the incarnation, but then a second and third one appeared.

It was really a difficult wheel battle. The prince tried his best to defeat six incarnations of himself, but he could not defeat the seventh one in any case.

Finally, the seventh incarnation pierced the prince's heart with the Seven-Star Sword in his hand, blood spurted out, and blazing black flames immediately enveloped the prince's body.

But here, the content shown in the mural also stops abruptly.

"Have you stopped painting here?" Robin couldn't help frowning.

According to what Maya described before, the next step should be for the prince to be controlled by the Seven Star Sword, stabbing his biological father to death and destroying his country.

After regaining his sanity, he chose to sacrifice himself and sealed the Seven Star Sword with his life.

The reason why the painter of the mural did not include the second half of history may be because he did not want to record the prince's guilt so clearly.

How did the prince seal the Seven Star Sword in the end? Is there really no record here?

Robin once again looked at the murals depicting the battle between the prince and his seven incarnations, and her intuition told her that these metaphorical murals hid mysteries.

By the way, there are also the seven sword monuments.

Robin looked towards the center of the underground palace, only to see that a certain glasses had already arrived in front of the seven sword monuments and was looking at them quietly.

"Did you find anything Sherlock?"

Walking to the side of the magician, Robin asked softly, and was immediately attracted by the inscriptions engraved on the sword tablet.

Fear, anger, hatred, despair, arrogance, greed, jealousy Robin frowned slightly.

"Robin, among these seven negative emotions, who do you think the prince lost to?"

Sherlock pushed up his glasses slightly and asked without looking back.

Robin pondered for a while, shook his head and said, "I don't know. I can't think of a person as powerful as him. How can he be defeated?"

The world's greatest swordsman thousands of years ago, equipped with a seven-star sword with a destructive power comparable to ancient weapons, his strength is enough to sweep the Grand Line.

In fact, he almost did it

In the opinion of a certain sinister woman, the last prince of the Kingdom of Askar can already be regarded as the strongest combat unit in history.

"Yes, he is too powerful. The only thing that can defeat him is his own heart." As he said this, Sherlock had a thought in his mind.

Mirror Entity: The Black Knight.

A huge black knight's armor appeared out of thin air. It walked with heavy steps to the sword monument with the word arrogance engraved in ancient characters, and reached out to hold the hilt of the sword.

"The more powerful a being is, the harder it is to overcome the arrogance deep in his heart."

唰

The black knight pulled out with force, and the huge cross sword was pulled out by this brute force. Then he heard the sound of Caracalla's mechanism, and the entire underground palace began to tremble violently.

Under the gaze of the two men, a hole opened out of thin air in the ground between the remaining six sword monuments.

A black sarcophagus with a simple shape slowly rose from the ground.

"The Coffin of the Last Prince" x2

Sherlock and Robin looked at each other, then walked forward together.
