Ji Yun planned to start with the books of the Thunder Mysterious Energy, browse them one by one, arrange them in order of the old and new, and then look at the most recent ones according to the oldest. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 Of course, the so-called "recent" is also at the end of the Mysterious Demon Era!

In the meantime, Ji Yun also went back and brought Ning Feng with him, intending to scan these books into Ning Feng's database, but found that on the top floor of the library, although there was no one to guard it, the thick metal door only allowed himself to enter alone, blocking Ning Feng from the outside. And it seems to have aroused the detection of the library's intelligent system, and even the watch that Ji Yun was wearing on his wrist was left outside the door.

It's easy to say, but in fact, it makes Jiyun extremely headache. The synthesized voice continued to rise: "You have an electronic device on you, please remove it and verify your identity again." It wasn't until Jiyun removed the watch and placed it on the ground that the alarm sound was cleared and Jiyun was able to enter.

The Thunder Xuanneng manuscripts in chronological order, these precious materials lay quietly on the ground, and Ji Yun began the long process of gnawing books.

Due to the influence of the knowledge of the Xuan Energy Improvement in the powerful database of Ning Feng, Ji Yun found that the knowledge of the Thunder System Xuan Energy was not weak, and he could understand it completely. In the process of reading, I continued to confirm with what I had learned, and many of the originally ambiguous details suddenly became clear. It's just that the words and sentences of the literary atmosphere make me very unaccustomed to it.

As for the gossip that Ji Yun paid the most attention to in the Xuan Demon Era, it was also very fruitful! However, the more he knew, the more questions he had in his mind!

It is recorded in "Xuan Demon Jian": "Metaphysics refines gods, and demons refine bodies, with different directions and different powers." However, the cultivation is supreme, all laws are one, the mystic calls for wind and rain, moves mountains and reclaims the sea, and the demons can also destroy the withering and decaying, and reverse the stars. ”

"Lei Xuanzhi" recorded: "The thunderer, the power of judgment, judges all things in the world, and the strong such as Xuanzun and Demon Zun, under the power of heaven and earth, also crush bones and scatter ashes." Lei Xuan, heavy meaning, not heavy form. Between heaven and earth, does thunder and lightning have a tangible call? Lead the thunder into the body, and get under the bottom. To make thunder in the sky is superior! ”

This kind of pure theory, Ji Yun looked at it and realized something, but he was not interested in it, so he had no choice but to read a lot of books, just like the ancient story told by "Forgotten Dust Codex", but he never saw it again.

Soon, Ji Yun finally turned to another copy, "Thunder Codex"! The author is a Xuanzun again! Ji Yun wailed in his heart: "The era of the Xuan Demon really belongs to the world of the Xuan Demon!" There are so many Xuanzun! ”

The world depicted in the "Thunder Codex" subverted the impression that the demons had just been established in Ji Yun's mind in a short period of time!

"In the winter of 1411, the seventieth birthday, the snow in the city, the friend of the demon master Qin Pei, thousands of miles to step on the clouds, gave the demon classic "Jing Lei", said that I should refine the body more, in order to release the thunder and worry about the fatigue after the mystic......"

Reading this, Ji Yun's heart moved, this short line of words actually revealed two important information! Xuan Demon is not as stated in the "Forgotten Dust Codex", he is naturally hostile, as early as more than 800 years before Forget Dust Xuanzun, Xuan Demon can actually become friends, and between the lines, he does not feel that Thunder Xuanzun has any mustard for people who learn demons! It seems that during that period, the Xuan Demon could have been so friendly!

Another important piece of information is that although I don't know if Thunder was already a Xuanzun when he was seventy years old, the Xuanxing cultivators at that time also had a period of fatigue after using Xuanqi, which was the same as now!

Ji Yun continued to flip back, looking for information of interest.

"When I heard that King Xuan was coming, the whole city celebrated, and those who were not powerful above the Xuan Master were not allowed to meet my king! I am fortunate to bring the Xuanzun to the first level, and I can see the demeanor of my king...... On that day, the sky broke through the huge hole, and the strong suction rose from the ground, and I finally knew why I couldn't see it if I wasn't a Xuan Master! The hole is black, as if there is a hidden thunder light, a little time, like thunder and lightning shooting the sun, from the black hole, condensed into a human form, the face is unrecognizable, the green robe and robe, the hem of the clothes moves with the wind, and behind my king, the black hole gradually disappears......"

The appearance of King Xuan in the record of Thunder Xuanzun is simply too stylish, and the Jiyun who sees it has an immersive feeling. I just don't know if the black hole in the note is the same thing as the black hole in the starry sky, or if it's just the ancients' self-name for the black hole - this is unknown.

Put down the "Thunder Codex" and pick up the next one, the above content is hundreds of years away from the Thunder Xuanzun. In this book "Leaving the Dead", there is a text. This text slightly reveals the signs of the confrontation between Xuan and Demon in that era of Xuanzun.

"It has been more than 700 years since the miracle of King Xuan, but I didn't expect King Xuan to have the power of immortality, and I hope that we will also get the throne one day......"

"Why is my king so angry? I can't solve ......"

“…… Declare war on demons! We are the king's subjects, and we will fight to the death! However, Xuan and Demon are one, if there is a war, where will my wife Zhen go......"

“…… escaped with the demon wife, met the pursuers, the battle, fourteen days and nights, Lei Xuan was exhausted, Zhen fought and I slept, Zhen was lacking and I fought...... Thirty and four ...... of the enemy"

“…… Tired...... The cause of the great war cannot be understood, and the will of our king cannot be violated...... But I want to return to the mountains and forests with my demon wife, and I don't ask about the world, but heaven and earth will not allow me...... Tired...... Tired...... Cease...... Cease! ”

Ji Yun's heart was extremely heavy, it seemed that the confrontation between Xuan and Demon was not like this from the beginning, but under the order of King Xuan, he launched a siege and killing of the Demon Master, and no one knew the reason for this!

It seems to have touched the secret of the rise and fall of the Occult Demon Era, but he can't fully know it.

As the last book was finished, Ji Yun only saw one piece of useful information, from "The Last Days":

"A fire has fallen from the sky, purple light has roared, aliens are rampant, and our mystical beings have fought to the point of exhaustion, and there is no longer the strength to resist...... Is it a foregone conclusion that human civilization will be annihilated? But if the ancestors and demons will be in the same place, and the demons will work together, how can there be alien shapes! Sigh! Sigh! Sigh! ”

It has been more than half a month since Ji Yun entered the top floor of the library, and he has been dealing with these books all day long, as if he has become a historian!

After reading this "The Last Days", Ji Yun went crazy, not only rummaging through the Thunder Xuanneng books, but also turning over all the books of that era one by one! helplessly found that people at that time seemed to have completely lost the idea of life, and they all chose to accept their fate just like the last three sighs of "Doomsday".

The alien in their mouth may be some kind of monster, and it is this kind of monster that has erased the Xuan Demon Civilization. And thousands of years before the end of the Xuan Demon Era, the Xuan King seemed to have a falling out with the Demon King and launched a war for the ages, which made human society lose an important corner, and the metaphysical world also suffered heavy losses.

Judging by the information gathered, it seems so.

The soul of gossip that was burning in the clouds was finally satisfied and gradually extinguished. He finally remembered that when he came to the library, he originally had the original intention of participating in the study of the Thunder Xuanneng manuscript, but now it is good, and the cheats are used as storybooks......

However, in this process, Jiyun has obtained a huge amount of information, but the focus is reversed. He hurriedly settled down, grabbed the compressed biscuits and the like he was carrying, took a hard bite, and carefully read the experiences related to the thunder system's occult energy.

These are all the notes of Xuanshi and Xuanzun, no matter how much knowledge in the Condensing Wind database is, it can't be compared to the experience of these great energy people when they are improving and groping!

Ji Yun settled down this time and really devoted himself to learning!
