Passing through the long tunnel and entering deep into the bunker, a hidden story awakens. A giant spaceship moves in the darkness, and the sleeping space slowly wakes up. At that moment, the existence of the multiverse reveals itself.

Here, the secret is revealed that Wansan Bunker was a secret laboratory studying the multiverse. The laboratory was researching a stone monument engraved with the Cheonsang Yeolcha Bunyajido (Joseon's celestial map). In Joseon's astronomical map, a constellation named 'Jongdaebu' appears, which was considered a key connecting to other dimensions. As the secret of the constellation is unveiled, the multiverse world slowly emerges.

As particles of light gather, a gate connecting dimensions opens. In a space made of mirrors and light, a passage leading to another world reveals itself.

Arriving beyond dimensions, a massive crack occurs at the center of the planet. The worlds of red flames and ice collide, and different dimensions begin to mix.

The landscape is inverted. Trees from the real world grow on the ceiling, while trees from the multiverse world glow on the floor. Two worlds meet in a single forest.

Time begins to flow over the river of the multiverse world. Colors change as day and night alternate, and alien plants and creatures reveal themselves.

A giant spaceship for exploring the multiverse world reveals itself. As the spaceship moves, the voyage toward a new dimension begins.

Imaginary drawings enter the multiverse world. The drawings become new characters and start to move within the world of the video.

Beings from another dimension reveal themselves. The alien lifeforms react to movements, mimicking the same actions as if communicating with each other.

At the end of the long exploration, the final portal opens. Light connected to the solar system appears through the bunker's ventilator. Passing through the multiverse world, you return to reality.
