The Ice and Fire Yin Yang Well is present in the Sunset Forest.
The hot spring isn't large, it is however split into two parts. In the oval pool, the waters of the hot spring is separately colored milky white and vermilion. Even more bizarre, even though they were in the same pool they remained clearly separated, not encroaching on each other and constantly keeping to their own sides.
It is said to be one of the three great treasure bowls, an extremely rare and valuable natural environment.
Ordinary plants are basically unable to grow in this environment since they cannot adapt to the special atmosphere, but certain valuable plants can nevertheless be cultured. The time required for cultivation of rare plants would be reduced tenfold.
The Ice and Fire Yin Yang Well isn't just for growing things. At the same time it had extremely unusual effects on the human body. If humans or maybe animals stayed at the side of the Ice and Fire Yin Yang Well, then in a very short time their bodies would be attacked by two kinds of extremely potent Heavenly spiritual influences. If they didn’t leave fast enough, their bodies were bound to burst and die.
