The tree inside this forest were all resistant to fire. They even emitted fire! The grass...nah there weren't any grass on the ground. The ground itself was made from magma stone. Every step you placed on the ground, you will feel the heat burn through your feet.
The ground was bright red as the ground was covered with magma stone. The magma stone was very very hot. The air inside was extremely hot that people need to continuously use their cultivation energy to protect them from the heat.
This place was still hot even when it was winter right now! Bah forget snow you couldn't even feel cool breeze in this forest!
Actually this place they called hell forest was only a bit part of the true hell. This place wasn't called hell forest but hell valley instead. This forest was located in the entrance of the valley and the flower bloom deep inside the valley.
