The landscape passed quickly as Archer watched the snow-covered hills end at the shore, where the rough waves crashed against the seawall he erected for safety. When the train passed, he saw the giant wall protecting the island from invasions or sea monster attacks.
'This thing will stand for thousands of years,' he thought with a smile.
It stood so high that he could barely see the top where the Titanwrath Cannons were situated to protect from incoming enemy fleets. Archer saw thousands of soldiers patrolling the walls or forts connected to the seawall.
The wall was lit up thanks to mana lights powered by Manaheart Engines and the dozens of mines found on the seafloor. Archer had used Mana Manipulation to create a vast vault under the palace.
Only he and the women could enter, thanks to the mana device he had Dellah make. This device allowed them to enter a secret metal door behind a secret room leading down to the vaults.
