Ling Zhenfei directed a stream of Northern Spiritual Energy into the Phoenix Elixir Furnace, and the aura on it changed instantly. A flame leapt up, and Ling Zhenfei directly guided the flame beneath the stone slab.
It was as if the flame from the Phoenix Elixir Furnace was directly burning this stone.
The stone slab was fixed by Ling Zhenfei onto several other stones, resembling a table.
After the flame from the Phoenix Elixir Furnace, the stone slab turned red-hot, which was incredibly astonishing.
Sun Wei commented to Zhang Zhenlin on the side, "Is this thing stone or iron? If it were ordinary stone, in this situation, it would certainly have already exploded from the heat."
At this moment, Ling Zhenfei stopped the flame, then began placing wood beneath the stone to burn it directly with wood.
The stone slab gradually returned to its normal black color, but everyone could feel the heat coming from it.
