According to the book, after the creation of Heaven, humans and demons descended into this world at the same time and developed separately.
In the beginning, the demon race's physique was superior to the human race's, and they had the upper hand.
However, as time passed, more and more sages of the two races created various cultivation methods.
The great cultivation era had begun!
The human race was more intelligent than the demon race. They slowly reversed the decline and became the masters of this world.
The demons could only live in the shadow of the humans.
Because the records were rather vague, Su Mu didn't know how long ago the 'primordial' in the book was.
However, from this book, it could be seen that both the human race and the demon race were becoming more and more powerful as they developed.
Whether it was his overall strength or the exquisiteness of his cultivation method, he was climbing to a higher level.
