The Dayin Dynasty is the overlord of the entire world, both in terms of population and land. The Dayin Dynasty was founded for 1,500 years, like an old lion entrenched in the center of the Central Plains continent.

In the center of the Dayin Dynasty, there is a mountain, the top of the mountain is covered with clouds and mist all the year round, this mountain is the world-famous Qianyuan Mountain, there is a academy on the Qianyuan Mountain, Lang Lang does not feel that the sound of reading floats out from the academy. Qianyuan Academy is divided into an upper courtyard and a lower courtyard. Only those who have more than one grade can go to the upper courtyard for further study, and those who are lower than one grade are in the lower courtyard. The cultivation of the dean of Qianyuan Academy is unfathomable, because of the existence of Qianyuan Academy, the Great Yin Dynasty can stand tall for so many years. Qianyuan Academy is also the only one that accepts apprentices who does not emphasize cultivation or qualifications. The rules of Qianyuan Academy for accepting apprentices are strange, maybe the dean glanced at you, and you are a child of Qianyuan Academy. People all over the world laughed and said that if you want to enter Qianyuan Academy, you just look at fate, if you have a fate to come in, you don't have a chance to get out. Qianyuan Academy accepts apprentices once every ten years, and the number of apprentices is uncertain.

It's such a weird academy with some of the best people in the world. On this day, in the upper courtyard of Qianyuan Academy, in the Astrology Pavilion, Niu Qingcao, the dean of the academy, frowned as he listened to the report of the astrologer Lu Lin.

"Lord Dean, the day has come again when the demon spirit will descend once every four hundred and forty-four years. The hexagram shows that the demon spirit has descended in the Great Zhou Dynasty this time, and the specific location has been deduced, do you want to take a look? “

Niu Qingcao took the results of the deduction and looked at it, and his brows furrowed even tighter.

"Do you have to get rid of it? Ouyang Tianci's family has a great favor to the world, it's a pity. The Dean shook his head.

"Lord Dean, a child with a demon spirit will only appear once when he is ten years old, and I have wasted a lot of energy to deduce that it is where the mansion of General Ouyang Tianci of Wind and Thunder is located. “

"Shadow, send a demon removal order to all sects in the world, and let it assist in catching demon spirits alive. “

In a dark corner, a rippled man saluted the cow grass and slowly disappeared.

A month later, Ouyang Tianci was killed, and the family was wiped out. The body of Ouyang Tianci's daughter Ouyang Yun'er has never been found, and no one is missing.

Qianyuan Academy once again invited all the major forces in the world to discuss countermeasures against the demon spirits.

Most of the people in the world have eight veins, and occasionally there are geniuses with nine veins, but above the nine veins, there is also a tenth vein, and people with demon spirits not only have the tenth spiritual vein, but the attribute of this spiritual vein is also very weird, and the attribute of this spiritual vein is devouring. So far, this is the case in the whole world. Every 444 years, demons descend. People who possess demons, because of the devouring, cultivate quickly, and can devour anything in the back, whether it is a big tree, a small grass, a person, an animal, as long as it is swallowed by him, it will become loess, and it will also increase with the increase of devouring, the realm is more profound, more evil, intelligent and cunning, which is also the most terrifying.

Therefore, it was agreed that the demon spirit would come and get rid of it at any cost. It cannot be allowed to develop, otherwise the consequences will be unimaginable.

This is also the reason why Qianyuan Academy did not hesitate to kill Ouyang Tianci to get rid of the demon spirit.
