Chapter 728: Building Connection To An Underwater Dungeon 2
It was large enough to house over 200 people at once, with two floors and five rooms, and a large living room for each floor, along with the basement.
A large circular cut was made in the basement floor, which Damian fitted with a meters-thick ring of condensed steel. Only one spell was engraved on it—an invisible box spell with no gap between the two walls at all. The shape was circular, like the steel ring. It was meant to work as a glass-like window to see beneath the ocean.
Along with that, Damian installed a simple steel pillar of the same size as the ring, which was around 60 cm in diameter. The pillar had the wormhole spell, the distance of which was set by Damian to open directly beside the abyssal pitch-black vertical opening of the dungeon underwater. The entrance of the wormhole would take the size of the translucent window he had made with the steel ring on the basement floor.
The steel pillar had a mana liquid tank and a lever for activation—the invisible box window was always active, also with a liquid mana tank. It didn’t need a lot of mana; the tank Damian had filled now should last at least 5–6 months.
The wormhole needed a direct path to work—only a third-ranker runesmith like Damian could etch a wormhole spell that could open so far using his own transcendent eyesight. Once he used the spell, it was recorded, but still needed a clear path to work.
He also put measures in place to seal the basement with a steel airlock to protect the wooden platform against flooding on the basement floor.
It was easy enough to use. One just had to pull the lever, and a wormhole connecting to the dungeon underwater would open up. The demons just had to jump in one by one.
Using the same four chains for support, Damian also built an underwater platform where the wormhole would open up and where the people coming out of the dungeon would land. This was not made of wood, though—Damian used a large, rectangular, door-sized, pure condensed steel cube with a liquid mana tank. The only spell on this one was also an invisible box spell, just sized 50 meters on all sides.
The invisible box would form above the cube, so there would be nothing inside the invisible box other than the dungeon entrance. Damian used wormholes to empty it completely of the water. The invisible box spell was connected to the mana tank by Damian’s mana threads—it was big enough to keep the spell powered for more than 7–8 months. The tank was also fixed in the water using the four chains. If it moved up and down a little with the water, the invisible box would not move along with it.
Still, the issue of having breathable air inside would persist. Damian had already installed the same pillar that opened a wormhole in a straight path. Its setting would open the wormhole right inside the basement from this place.
