You Smell of Dragon Blood

The core concept: The world's first fully immersive VR cultivation MMORPG, marketed as the "Second World."

Realism: 99.9%, with all five senses fully simulated. Pain can be adjusted, but is enabled by default.

The secret: The game world is actually a fragment of an ancient cultivation realm, and the AI core is a dormant will from antiquity, revealed later in the story.

Time flow: 1 day in the game = 3 hours in reality.
