Sensing the malice from the one who summoned him (a summoner of the O’ltormea empire), he uses his martial arts to run away, killing important people of the empire during his escape. After the escape, he rescues two twin sisters from the hands of thieves. The sisters who can use magic, swear to serve him as subordinates. Thus, Ryouma begins his journey on the path of the supreme ruler.

Zong Shou woke up from a dream and realised that he had time traveled back ten thousand years, to an era before the God Emperor was had appeared in the world.

With a sound of “Boom”, a lotus fell from the sky and leveled a mountain.
Is it time travel? Is it crossing robbery? Or was Gongdou in the sky kicked down from the heaven by some fairy concubine? who knows?
Is it a fool? Is it a cannon girl? Or a magic stick? who can guess?
The imperial court set up the Ninth Gate and Eight Heavenly Dragon Guards in Da Nei to investigate supernatural events and difficult cases in various places.
Lin Tingjun, the god of Babu, came to investigate the matter of the fire falling from the sky.
However, Lian Youyou, a hot-mouthed girl, was stuck to her, her dead skin and rotten face was so sticky.
The white-haired wolf demon on the mountain, the noble son who turned into a butterfly disappeared, and the palace ladies who disappeared mysteriously…
A series of supernatural cases may seem like monsters acting as monsters, but they are actually humans acting as monsters.
The difficult and miscellaneous cases are definitely caused by people, and they are caused by demons and ghosts.
Is it someone playing tricks? Or a ghost? Is it a monster? Or be a monster? who cares?
Just as long as the people who eat melons express excitement!
After checking, why did Lin Tingjun and the other eight gods have their own goals and stories? Then who is she, Lian Youyou?
The ancient dimensional monsters are ready to move again, eyeing the earth!
Divine matters, demonic matters, monster matters, and human affairs are not as important as Lian Youyou’s protecting the earth!
