The Confrontation of Elbaf Arc with Egghead Arc in One Piece
The recently concluded Elbaf arc of One Piece officially competes with the Egghead arc in terms of plot density and grandeur.
The latest developments in One Piece could potentially solve a significant mystery surrounding the ancient weapon Uranus.
The Elbaf mural recently revealed contains many intricate details and elements of folklore, along with Harley’s discussions about the three world governments that can be interpreted in various ways, shedding light on the largest mysteries in One Piece. Some parts of the mural may hint at the practical use of the ancient weapon Uranus, and it is not something that people have been eagerly anticipating.

One of the most intriguing mysteries surrounding the ancient weapon Uranus is its potential to be a destructive force once activated. This phenomenon was first observed in Chapter 1089 after Lulusia was annihilated by Imu and the World Government. Vegapunk’s final communication confirmed that the weapon used on Lulusia was indeed Uranus. This revelation sparked theories about the underground capabilities of this weapon, which cannot be fully explained within the context of the Enies Lobby arc, leaving many to wonder if it is a product of using Uranus.
Now, the Elbaf mural distinctly hints that Uranus may serve a more profound purpose when utilized. The depths could represent a means to extract “fire from the earth,” as indicated in Harley’s discussions.

The Ancient Weapon Uranus Might Be Utilized for Other Purposes in One Piece
In the mural depicting the Adam tree located in Chapter 1138, part of the mural is believed to symbolize the most advanced civilization with a depiction of a human being, suggesting that these beings were granted access to Harley’s underground realm through an advanced mechanism resembling a type of conveyor belt to extract a specific type of light or fire. Harley’s discussions suggest that the most advanced civilization could have leveraged a type of “fire from the earth,” which may be the focus of the characters depicted in the mural.
The dark shadow in the mural resembles a type of cave or chamber above the surface, as the left side still features a large ship resembling Noah. Not too far above, the mural also shows a flying ship similar to Enel’s Maxim emanating lightning, implying that this flying ship could have been part of the Uranus weapon that attacked Lulusia with beams of light from above in Chapter 1060.

Therefore, it is possible that in the distant past, the ancient weapon Uranus was not used to erase entire civilizations but rather to create deep pits with the purpose of gathering this “fire.” The inner depths of the earth could have been a source of energy capable of yielding ancient secrets utilized in the advanced civilization, which even Vegapunk couldn’t replicate.
The use of Uranus as a material resource, as Vegapunk elucidated in his communications, is the primary reason the One Piece world is close to being entirely submerged in the advanced civilization. It is possible that this might not be the first time the One Piece world has faced such threats caused by uncontrolled technological advancements.
The infinite energy reservoir, however, could potentially lead to consequences for the environment, which may very well be the key to uncovering the truth behind the world’s impending annihilation in the most advanced civilization. The skyscrapers with heights depicted in the mural hint at this very idea. This detail could also be related to Vegapunk’s vision regarding the creation of a limitless energy source that could resolve various conflicts in the world.
However, with Uranus and the Mother Flame currently in the hands of the World Government, it seems that the moment the ancient weapon is reclaimed by the hidden figure will be when the answers will finally come to light.
