The first thing that caught Yang Yi's eye was an actual photograph of Steam Island. It seemed to have been taken from a distance and was rather blurry.
The image showed vast stretches of abandoned factory grounds, severely rusted, with many factory buildings already collapsed and deserted.
Yet the perimeter of this island was lined with heavy weapons such as cannons, rockets, and autocannons, all covered in rust. Some were in better condition, while others even had barrels that had rusted until they bent or broke.
"This island resembles an offshore platform. It is entirely a technological construct, not a natural island, roughly circular with a diameter of about fifteen kilometers.
"A large number of heavy weapons of various specifications line its perimeter like a hedgehog's spines. Some are severely corroded, but most remain operational and possess astonishing firepower."
The information also included a photograph demonstrating their destructive power: a small mushroom cloud blasted up over the sea, with spray thrown hundreds of meters into the air.
"This is the explosive power of a small, rusted missile approximately thirty centimeters long. Its blast affected an area extending over five hundred meters. Few ships could probably survive a direct hit.
"However, these rusted missiles and shells have poor accuracy and rather erratic flight paths. They generally struggle to hit distant targets, provided not too many are fired."
Zhang Zhi had added this after the photograph. He had also tested the danger threshold: approximately twenty nautical miles.
There could be a margin of error of around one nautical mile, depending on the condition of the weapons on the corresponding side of Steam Island. But it was essentially certain that anything entering this range would be indiscriminately targeted.
At fifteen nautical miles, the sporadic missiles would turn into a hail of fire, delivering
