This seed is able to generate a unique island with sea ruins. You no longer need to dive into the ocean to find the treasure. The ruins are located on the surface of the island, which allows you to fully study the principle of the structure of such buildings.
Look for the island is not necessary, because spawn is located directly on it. Destroying the protective layers of sea ruins, you can find a chest in which there will be many useful items that will help you survive.
Another amazing thing is that right in the middle of the island generated a huge gap, falling into it, you will die immediately.
This island with Sea Ruins can be a great place to survive, because the set of initial items is very narrow, and the environment is very dangerous.
