He discovered that the ground beneath his feet was not ordinary, but a type of metal.
It was a dark red metal with strange patterns carved on it.
The entire ground was made of this metal.
Lu Ming walked to the side. After about six hundred meters, he saw the wall. The wall was also made of this kind of metal and there were floral patterns on it.
Buzzzzzz!
Lu Ming took out a level-four saber from a storage ring and slashed at the metal wall.
The saber shook and was bounced away. There was not even a mark on the metal wall.
"This can't be an alchemy furnace right?"
Lu Ming suddenly had a bold guess.
The deep pit and the surrounding metal walls made Lu Ming think of an alchemy furnace.
It was an alchemy furnace with a diameter of more than a thousand meters and a depth of several thousand meters.
At the thought of this, Lu Ming gasped in shock.
With such a huge alchemy furnace, what kind of elixir was he going to refine?
Buzzzzzz!
