The next day, after seeing the vast sea, everyone finished breakfast and prepared to return to the walls.
But just as the Survey Corps was packing up its equipment...
"Tooooot-"
A sudden blast of a horn broke the peace of the previously tranquil sea.
The horn was so loud that everyone present heard it at once.
"What's going on?! What was that sound?"
"Look! What's that?!"
"Is that a ship?! How can it be so big?!"
Everyone looked toward the sound and saw a twenty-meter-long vessel on the sea, fitted with numerous gun turrets they had never seen before.
Black smoke kept pouring from the vessel's smokestack.
With his sharp eyes, Arthur could clearly see numerous soldiers in unfamiliar uniforms standing aboard.
Arthur's expression immediately turned cold. He knew this had to be a vessel from Marley.
"Is that a Marleyan vessel? Have they come this soon?" Hange was a little nervous. She knew that Paradis Island's current technology and military strength were nowhere near enough to contend with Marley.
Arthur shook his head, rejecting Hange's suggestion.
"It's probably a reconnaissance vessel, or Marley has brought more Eldians to Paradis Island to exile them."
"Everyone, hide immediately! Under no circumstances can we let them spot us." Arthur made a swift decision and issued his orders.
"Yes!"
At Arthur's command, the Survey Corps soldiers immediately sought places to hide to avoid being seen by the Marleyan soldiers.
Once everyone was hidden, Arthur took out his binoculars and began observing the activity aboard the vessel. Fortunately, the Marleyan soldiers seemed very lax and had not noticed them.
"Eren, I might need you to dive beneath the sea and use your Power of the Titan in a moment." After some thought, Arthur had devised an excellent plan in his mind.
"Dive underwater?" Eren
