The soldiers of the Mars Revolutionary Army that were just arrived all screamed in exasperation while Feng Lin had already traveled far away by controlling the furnace.
The furnace was used as a boat; the lava was treated like the ocean.
The underground tunnel twisted left and right, extremely winding and complicated.
