Immortal Cultivation: I Evolved into a Prehistoric Beast

Others cultivate immortality to seek immortality, but I cultivate immortality and become a giant beast. Traveling through the world of immortality, Qi Bei was able to bind spiritual beasts into external incarnations and gain the ability to continuously devour and evolve. As the external incarnation evolves, the stronger the body's cultivation is, the longer its life span will be. Others have been practicing hard for decades and cannot make breakthroughs. All I have to do is let the spiritual beasts transform into the prehistoric beasts of myths and legends. The body length is hundreds of meters, kilometers, tens of thousands of meters... A hundred years as usual, a thousand years of appearance, and ten thousand years later... He looked at his giant golden-scaled claws that were comparable to mountains in the sea of clouds, and then looked up at the furious thunder calamity above the nine heavens. Until that day, the army of the cultivator world pressed forward, trying to kill the demons, but saw the shadow covering the world slowly opening its eyes - "I just lived for too long, how can I become the natural disaster that you call the world?"
