There were two places for Foundation establishment. One was the yin-attribute altar in the underground ice world, and the other was the Yang-attribute altar on the surface.
One Yin and one yang, they just happened to fit the layout of this world.
For ordinary cultivators, they only needed to find one altar to successfully establish their Foundation. However, Li Tian had to find two altars before he could complete it. Otherwise, there would be flaws and hidden dangers in his body.
Therefore, in comparison to Li Tian, the key to breaking through to the physical Foundation Stage was to find another yang attribute altar in the desert.
Otherwise, without the tempering of the Yang attribute spirit energy, Li Tian would never be able to balance his yin and yang and achieve perfection in his life.
He had to find it!
Li Tian Tian made up his mind and quickly travelled through the desert, constantly sensing the fluctuations of yang attribute spirit power.
