The Five-Color Divine Light at the Beginning: My Magical Power Comes from Prehistoric Times

[Revival of spirit + single female protagonist + no system + high burning + strong pleasure] Thousands of years ago, a heavenly book came to the world with the seeds of spiritual energy, which expanded the area of Tianyuan Continent countless times, and the spiritual energy recovered since then. The human race was overjoyed, thinking that it was a blessing from the gods, from which they could seek a way to escape. However, they did not expect that with the recovery of spiritual energy, one hundred and eight secret realms would suddenly appear on the Blue Star. Because there were many forests and miasma in them, it was difficult for mortals to survive. The world called it the "Mysterious Forest", but more people were more willing to call it the "Devil Realm". Because what emerged from that so-called secret realm was not an ancient god, but a terrifying demon clan... As the spiritual energy spreads, the demon race becomes wise, absorbs the spiritual energy and strengthens itself, while the human race is physically weak and finds it difficult to compete with the two races. The ancestors of the human race went through hardships and dangers, read the heavenly book and understood the Tao, and figured out the method to strengthen themselves, which is called cultivation. Today, on the Blue Star, humans, monsters, and demons stand in harmony among the three races. However, under the seemingly stable situation, there are terrifying waves hidden. When the real truth comes, how will the human race bear it... All this may be answered after the young man named Su Li comes to this world inexplicably...
