Rakuin no Monshou - Volume 3, Prologue

The Prea gods, who saved humanity from living as slaves to other races and established the human empire, passed down their bloodline. Those who inherited their blood were born with magical talent and could become wizards. After thousands of years, the empire fell, and the world became ruled by great masters across different regions.He was a young man who grew up with his mother, never knowing who his father was. Though he possessed tremendous magical abilities, he lived as a shepherd in a rural village. Now he ventures out into the world to discover the secrets of his bloodline.

Zhong Yansheng lived for eighteen years. After accidentally falling into the water, he dreamed and found that he was living in a book. In the book, he was a fake young master who was mistakenly adopted by the Marquis. After the real young master came back, he {real} was not taken seriously by the family and was driven to a separate courtyard in the suburbs of Beijing. His parents only doted on him {fake}, and they turned the real young master into a black hearted man, and finally his family was ruined. After waking up, Zhong Yansheng learned the news that Master Zhen returned to the house three days ago, but the whole family only revolved around him {fake} who was sick.

The formless ancient world was infested with despicable demons. They hunted and feasted on mankind, keeping the human civilization constantly in a weak and suppressed state.

During the first known year, a magical mountain descended into the world from the realm of the Gods. Carved on this enormous mountain was a message: ‘Heaven Prevails’…

After the Grand Descent, a name that was given to the descending of the mountain, the Three Great Sages made their ways to Mystic Mountain where they learned to harvest what we now call magic, establishing the Mystic Cults and eighty-one sacred shrines to help aid mankind with the cult’s mystic powers against the eternal fight to the death with demons.
