Jiu Yu remembered what Di Mu Jin said, and after dinner, he came to the study of the Green Dragon Hall as promised. I have to say that the study room of the Qinglong Hall is embarrassing. Instructions on how books are categorized alone take up a piece of the wall.

Di Mu was not there, Jiu Yu and the others were really bored, so they simply flipped through the books on the shelf.

In the study, ninety percent of the shelves are books that record the immortal law. Facing one neatly arranged bookshelves after another, Jiu Yu couldn't help but sigh, how many hundred years would it take to learn these immortal arts.

A large number of immortal methods were placed in front of him, and Jiu Yu had no intention of studying them. At the end of the study, a bookshelf in a corner caught Jiuyu's attention.

On that shelf, all the books were very worn, but there was not a trace of dust on the shelf, and it was clear that someone was often flipping through it.

"General History of the Demons", "Legend of the Demons", "Demon Words", ......

Looking at the bookshelf full of books about the demon race in front of him, Jiu Ying couldn't help but take a copy of the "Demon Monarch Collection" and read it.

"Chaos opens, divides yin and yang. The gods are born, and the demons are born. The demon is nirvana, overcoming thorns and thorns, and unifying the demon race, which is the first generation of demon lords. After reading a few lines, Jiu Jue turned the book to the end and muttered, "Ninety-seven thousand five hundred and sixty-one years of creation, the eighth demon lord Niryu Xing ascended the throne......"

It is now the 101,000 years of creation, so in this way, Nirvana Yuxing has ruled the demon race for more than 3,400 years.

Seeing this, Jiu Jue suddenly became interested in Nirvana Yuxing, and just as Jiu Jue was about to continue looking down, Di Mu Jin appeared in the study at some point.

"After reading so many history books of the demon race, it is better to learn more immortal arts."

Jiu Jue turned around, and Di Mu Jin was sitting at the desk, tidying up the books on the table.

"There's no dust here, don't you see it often?"

"It's boring, just passing the time."

When he answered, he didn't even raise his head.

Jiu Jue felt more and more that Di Mu Jin was a boring person, put the book away, walked to the table, and Jiu Jue slapped his hands on the table.

"So, what do I need to do?"

"I have a list here with the names of the new Qinglong disciples written on it. After that, you will be responsible for keeping track of when everyone becomes an immortal. ”

Di Mu handed over a thick booklet, on which clearly recorded the information of each disciple.

"That's it?"

Jiu Jue stared at Di Mu Jin's eyes and questioned.

"Of course there are others"

Di Mu Jin waved his hand, and a pile of tattered booklets appeared at Jiu Jue's feet. Some of the booklets are even torn and only half a copy.

"These are the rosters of previous editions, and the other day the Brilliant Xuanwu Beast was messing around in my study and messing up the books. I want you to tidy it up for me. ”

Hearing this, Jiu Jue understood that Di Mu was looking for her, and he was simply squeezing his own labor. However, thinking that he was not only not Di Mu Jin's opponent, but also had to call him Master in name, in the face of Di Mu Jin's request, Jiu Jue couldn't refuse at all.

"In return, I can tell you the story of Nirvana."

Originally, he was still losing his head, but when he heard Di Mu about to tell him the story of the demon clan, Jiu Jue's eyes suddenly lit up.

While sorting out the books, Di Mu Jin told the story of the Demon Lord with Jiu Jue.

In the thirty-seven thousand five hundred and sixty-first years of creation, the patriarch of the Qiqi clan, Ni Yuxing, ascended to the throne and became the eighth demon lord in the history of the demon race. Niryuxing has a very good method of managing the demon clan, and during the period of his rule, the demon clan grew rapidly. In the 39,400th year of the creation of the world, Nie Yuxing married Gu Xi, a woman of the same clan who was 1,500 years younger than himself, as his demon princess. A thousand years later, Gu Xi gave birth to two princesses, and then disappeared into the history of the demon race.

"Disappear?"

Jiu Yu was very puzzled, what did it mean to disappear.

"A thousand years ago, when the Demon Princess gave birth, it was during the war between gods and demons, and the two worlds were in turmoil. At that time, the Demon Princess suddenly disappeared with her two children. And after the war, Niryuxing made a contract with the previous God Emperor that the two clans would never be disturbed again. Since then, the Protoss has completely cut off contact with the demons, and we have no way of knowing what happened after that. So the writing stops here. ”

"So in the thousand years after the Great War of Gods and Demons, we don't know anything about what happened in the territory of the Demon Race, right?"

Di Mu nodded, his hand arranging things, and paused for a moment.

"Then if the demons raise an army again, won't we be prepared at all."

Hearing Jiu Jue's question, Di Mu calmed down and patiently explained to Jiu Jue, "There is an enchantment at the junction of gods and demons, and the demon army cannot cross the boundary. ”
