The heat waves from the lava sea radiate throughout the entire underground world.
This is directly manifested on the stone pillars supporting the world. The rock face closer to the lava sea is more fragile and mottled; a light touch with the palm causes dry stone fragments to crumble and fall, plummeting tens of meters down into the city.
The sulfur-scented hot wind blows through his hair tips, and Lu Li gazes out over the underground world.
Below his feet, the Lost Giant City is located at the center of the underground world. On one side is the downstream lava sea, its far end distorted by the heat waves, obscuring what lies beyond. On the other side, upstream is lit by a lava river, stretching into the gray depths.
The slightly narrower ends are also over ten li wide.
The underground world is shaped like a wide river.
Lu Li stares into the depths of the underground world.
If it weren't for the conspicuous city, he might have followed upstream after emerging from the hole.
