Catacombs.

Before leaving, Sebastian decided to stop and go through an adaptation that he hardly paid attention to before since he bought it due to the conditions of his environment and a ton of other reasons.

[You have triggered Adaptation: Map.]

Yes, his map adaptation was one of the few add-ons that he neglected a lot in his body since transmigrating into this world.

It was not his fault, it's just that the always eventful situation of his surroundings left him with little time to pay attention to it.

As soon as he triggered the adaptation, he felt like a huge virtual map appeared in his imaginary vision.

The map currently had only 2 regions, a region represented by the normal green color of the Green Mist Sea and the other that was tainted with a deep redness that was glaring to the eyes.

These 2 regions were his previous location in the wide expanse of water and his current location in the ocean volcano.
