Multiple crucial events occur in “One Piece” Chapter 1138 named “Harley” which means Sacred Text. Franky along with the Giant Ripley encounters the ancient painting in the Adam tree which was drawn during the void century.
Ancient Mural and Impending War
Franky observes a prehistoric painting alongside Ripley who stands as a huge biology educator within the Adam Tree’s interior. The painting comes from the Void Century marking a critical period in historical development. Through translation of the book received from Saul Robin discovered references to two historical wars and predicted the arrival of a forthcoming major conflict. The story becomes more complex due to new plot additions which expose character secrets and powerful abilities while revealing future conflicts that could dramatically shift world dynamics.
The translation work by Robin of the Harley Book
Robin uncovers distinct historical details which appeared in the Harley book after being provided to her by Saul from the Owl Library. The book narrates two vital wars from history while forecasting another major war yet to come. The historical discoveries follow a clear path toward revealing two past wars together with warnings about an impending conflict that will significantly affect global futures.

The fans predict Nika fought against Imu during the Void Century since both sought control of the planet. The defeat of Nika allowed Imu to establish control which led to the formation of the World Government. The contrasting representations of Nika and Imu and freedom versus control and secrecy—suggest an inherent ideological conflict. The opposing characters of Luffy and Imu seem destined to meet in what could turn into a future conflict about Nika’s role in the future. The emergence of Nika’s power within Luffy constitutes an open rebellion against Imu’s governance allowing him to potentially become the leader who will bring down Imu’s reign.

“First World”
There was fire on the land.
Humans succumbed to their desires
And touched the forbidden sun.
The Han people wished:
“The Sun God has appeared.”
The Earth God grew angry,
And together with the Serpent of Leaf and Flame,
Shrouded the world in death and darkness.
They would never meet again.
“Second World”
In the void, a demon wind blew.
The Forest God sent forth a demon.
The sun was engulfed in the flames of war,
And the god of the central sea raged.
The destruction only spread further.
The people of the half-moon dreamed.
The people of the full moon dreamed.
Humans killed the sun and became gods.
They would never meet again.
“Third World”
In chaos, there was emptiness.
The inconvenient remnants
Remembered the promised day,
And heard the voice of the broken moon.
“The Sun God dances and laughs,
Leading the world to its end.”
The sun returns.
A new morning will come.
Surely, they will meet again.

In the end of the panel, the author has placed a poetic lines that gives the detail about the three greatest world wars that happened and yet to happen. The author has hinted at the Third World War which is approaching very soon and will start from the island of Elbaph.
