Even with his Aura Domain activated, the doors still seemed to have been made up of gold.
They were five times his height.
It was only now that Shiro realize that the space inside the dungeon kept increasing.
Earlier, it was just a small passage with the ceiling being right on top of them. If Shiro had tried to jump, he would have bumped his head on the ceiling.
But now, as he raised his head, he could see the ceiling at the very distant end. He had to raise his head to the fullest and stare as if he was looking straight at the sky.
The doors had large and heavy chains attached to them, their distant end lying on the ground.
When Shiro took a look at them, he realized that the chains were made up of bronze, which was yet another important material.
The chains are large as mentioned, but not too large. They could fit in Shiro's hands.
